¿Metallic Additives, or sodium vapor at high pressure, for public lighting in Mexico?
For Iluminet • Aug 26, 2008 • Section: Features, SustainabilityLighting in the Public roadways in Mexico have been used various kinds of lamps from the last century to the mid-twenties entered the incandescent lamps of high power at the end of the fifties were incorporated vapor lamps Mercury in high pressure and since the end of the seventies began the use of sodium vapor lamps at high pressure.
Since the beginning of the first decade of this century is beginning the incorporation of the lamps of metallic additives in the Public Lighting of roadways in Mexico, which has generated expectations in the midst of the professional lighting of our country on its proper implementation.
Eng. Gabriel Torres Aguilar, Technical Consultant of TAG Lighting presents an analysis of the incorporation of the lamps of metallic additives in the Public Lighting of roadways in Mexico, which will determine whether we really have been the best alternative for replacing the lamps of steam High pressure sodium
Public lighting
The Public Lighting is a lighting system for public areas with vehicular and pedestrian traffic which provides a comfortable during the night:
- Roadways such as streets, driveways, roads, highways, freeways, primary and secondary roads, boulevards, and runners-type tourist and shopping among others.
- Urban areas such as squares, baseboards, parks, gardens, paths, walkways and kiosks among others
Lighting in the Public roadways in Mexico since the end of the seventies of last century, have been used sodium vapor lamps, high pressure, which will progressively have been replaced since the beginning of this decade by lamps metallic additives .

An Analysis
Here is an analysis of the application that have lamps additives and metallic sodium vapor at high pressure in the Public Lighting of roadways in our country.
For public lighting of roads have been used sodium vapor lamps at high pressure into semi-optic lighting with cutoff (semicortado beam), when required high levels of illumination on streets, pavements, roads, highways, freeways, roads Primary and secondary schools, among other boulevards, where it requires a great visual acuity of vision and high contrast, without the indispensable vision of the colors.
In the case of requiring high levels of illumination for public lighting of roads as runners-type tourist and commercial, which have high inflows of people into circulation or movement and requiring an adequate vision of the colors are used lamps of metallic additives.
In public lighting of roads as high-speed boulevards, driveways, roads, highways, roads, avenues and roads primary among others, that require high levels of illumination lamps are used metallic additives within optical cutoff luminaires (beam cut), which prevents the light output is sent to the top of the lamp and a high vertical control of the light intensity, which allows to limit the luminance (brightness) to the visual angle of the drivers.
Lighting for Public roadways low-speed roads, secondary roads and others that require low levels of illumination, the use of metallic additives lamps is not adequate because it does not require a perfect view of the colors, but only for a good visual acuity of vision and high contrast.
The use of metallic additives lamps is suitable for public lighting in urban areas such as squares, baseboards, parks, gardens, paths, walkways and kiosks among others, where the vision of colors is very important.
In public lighting of roads covered steps such as tunnels or underpass, where they require high illumination values, reduced recovery time before the glare, good contrast and vision of a lower luminance (brightness) of the lamp, are used lamps sodium vapor at high pressure.
For purposes of assessing the advantages and disadvantages of using lamps metallic additives and sodium vapor at high pressure in the Public Lighting of roadways in Mexico, the following is a table comparing its main performance characteristics and operation.
Comparative
Performance characteristics and operating | Lamp metallic additives | Sodium vapor lamp in high pressure |
Luminous efficiency | 70-100 lm / W | 90-150 lm / W |
Average life | 20.000 hours | 24.000 hours |
Performance Index of color | 65 Ra | 25 Ra |
Color temperature | 4100 K | 2100 K |
Lumen depreciation | 35% | 10% |
Contrast vision | Low | High |
Visual acuity | Low | High |
Pollution astronomical | High | Low |
Luminance (brightness) | High | Low |
Control of luminous flux | High | Low |
Conclusions
From the above information can be determined that the lamps of metallic additives have more disadvantages in the luminous efficiency, average life, lumen depreciation, contrasting vision, visual acuity astronomical pollution and luminance (brightness) over those with vapor lamps high pressure sodium, which must be held to determine whether the use of lamps metallic additives has been the best choice in public lighting of roads in our country.
Regarding the above should analyze the reincorporation of the legendary sodium vapor lamp at high pressure which was used for several years in a way more efficient lighting in public roadways in Mexico.

Dear Ing. Gabriel Torres Aguilar,
Lighting consultant.
I congratulate him because up until now had not been made public, that few people know:
The lamps of metallic additives, are a mindless spending for public lighting in general and especially for Mexico City. The most striking proof, Av. Reform night.
Some manufacturers, with profit motive and without scruples, have exploited the inability of government officials, to also make them believe they are the great innovators of street lighting.
Good for her participation a abrazo.

Dear Ing Villa:
I appreciate your comments and I agree with you. That the implementation of the lamps, metal additives in the Public Lighting Mexico City, was not one of the best decisions we took at the time the Director of Public Lighting of the Federal District government, Eng. Antonio Gershenson Tavelov.
In fact all this from the beginning of Urban Services Directorate General of the Federal District government, by its then owner of the Arch. Francisco Gonzalez, who in February 1998, conducted a survey technique with the leading manufacturers of lamps, lighting fixtures and balastros for street lighting, on the advantages and disadvantages of technical application of the lamps, metal additives in the lighting of the City of Mexico, which had as its results from 2000 onwards will begin to replace the legendary sodium vapor lamps at high pressure.
Since my early days as an engineer photometric and mechanical tests at the Laboratory of Public Lighting, is convinced that the best uses for lamp lighting the lamp is sodium vapor at high pressure, during my passage through Lumisistemas defended the position that the lamp, metal additive was not the best option and I am not convinced of its use in the lighting of our city (except in some exceptions).
Today I realize that in some vialiadades of Mexico City, mainly those that are in the delegation Venustiano Carranza (Circunvalacion and Axis 3 South to name a few), the sodium vapor lamp at high pressure is being implemented in lights again Canadian high-specification, with a degree of protection to the entry of solid and liquid particles-Ingress Protection IP66, in power of 150 W.
Even in the Churubusco bridge that crosses the Axis 3 East, has built-in lights that were initially sodium vapor at high pressure, were replaced by metal additives and finally won again the sodium vapor lamp at high pressure inside the latest generation of luminaries.
I believe that the sodium vapor lamp at high pressure even has a respectable application in the lighting of our city and country.

Dear Jorge Castle:
In regard to the information you. requires respect to making curves photometric distribution of its luminaries to the public and alumbado type projector lamps using induction of 40W, I would infrormarle that these are obtained in a laboratory test photometric, where he conducted studies on the photometric behavior and performance of a luminaire.
Studies on comportamieto and performance of a photometric lighting, basically are integrated on a report of photometric tests and their respective distribution curves (isolux, curves coefficient, classification nema, curves isocandela among others).
To obtain the reports and test curves photometric distribution of its lighting fixtures for road GPLI-12-40 and type projector GPLGL-12-40, both with circular lamps induction of 40 W, may be directed to Lab Public lighting of the Government of the Federal District, where you can evaluate your lighting, in terms of features mechanical, electrical and light.
He sent the contact details:
Public Lighting Laboratory of the Government of the Federal District
Lebrija not. 196 Col. Cerro de la Estrella, PO Box 09860, Iztapalapa, Mexico DF
Tel: 5426 2804, 5426 2759
Fax: 5426 2758
The luminaries of road lighting lamps with the induction inside, I had the opportunity to see them installed and operating in Toluca, State of Mexico and Lagos de Moreno, Jalisco, which are very similar characteristic to its luminaries GPLI-12-40 .
I believe that the technology of induction lamps can be a good alternative lighting inside the vial.

Good evening,
I have found a very interesting article. I am writing from Spain, where, fortunately, most of the lighting is developed in sodium. However, in medium and large cities, it is noted increasing proliferation of mercury lighting. This is due solely to their performance color. Despite being obviously a higher consumption of lighting and in an era where the premium savings and energy efficiency, lighting mercury is imposed where there is considered more important than the safety savings, and I talk about security in general: for pedestrians, drivers and for carrying out the work of the police themselves.
But I have a doubt that I would like to ask, should they decide to replace mercury by sodium, is the assistant of a team working for the other?, Is it enough just to change the lamp and no auxiliary equipment for power?
A greeting and wonderful article.
DEAR ING. GABRIEL TORRES ..
I HAVE READ WITH ATTENTION IS THE DOCUMENTARY OF LIGHTING, AND THE TRUTH I AGREE WITH YOUR ANALYSIS ON THE USE OF THAT IS A MUST GIVE THE LAMPS OF METAL AS ADDITIVES also ratified the steam high pressure sodium REMAINS IN TODAY THE APPROPRIATE FOR LIGHTING THE PUBLIC .. HOWEVER ARISING ME A PAIR OF QUESTIONS THAT Quies who supported me:
1 .- THERE IS A LAW OR REGULATION FOR THE MUNICIPALITIES THAT COULD BE WELL AND SUPPORT standardize DEBARAN TYPE OF LIGHTING THAT POST IN THE SERVICE OF PUBLIC LIGHTING AND NO Seceda what's happening OF POST FOR LAMPS I believe is the most beautiful, THE MOST ECONOMIC OR THAT BEAUTIFUL talked to me?
2 .- THE LAMP OF INDUCTION FOR PUBLIC LIGHTING AHI I BELIEVE THAT THE TRUTH IS NOT APPROPRIATE, It would LABORATORY CERTIFIED AS AN ENDORSEMENT TO THEIR RESPECTIVE TESTS, BUT ALSO YO VI TOLUCA IN THE LAMP POST ON THE AV. TEGNOLOGICO THE TRUTH AND I BELIEVE THAT WAS A Place on a HERROR AV. IMPORTANT AND practicing AV. THIS IS DARK AND LITTLE Fog EXISTERA the problem gets worse ... QUIZAS THESE LAMPS COULD BE USEFUL IN RURAL AREAS.
HELLO ING. LOOKS LIKE ME YOUR ARTICLE VERY INTERESTING, BUT ME COMENTANQUE magnetic induction lamps are more efficient and savings. NO COMPARISON BETWEEN ANY TABLE OF CONTACTS FOR THESE LAST? THANKS
Dear Antonio:
In most parts of the road lighting in Europe, it is estimated that there are at least about 35 million lights that use mercury vapor lamps at high pressure, that is about 1 / 3 part of the luminaries that exist throughout the European continent .
The technology used in these luminaries of mercury vapor at high pressure is at least about 25 years overdue. This ancient technology of mercury vapor lamps at high pressure has a low efficiency (35-60 lm / W) and half rate of return of color (40-50) and are installed in lighting fixtures in poor distribution of the light output utlizacion low rates, low efficiency and low protection against the entry of solid and liquid particles (IP 54).
As in some South American countries like Argentina, where the prevalent use of mercury vapor lamps at high pressure, its use in Europe is even contemplating this massive and make their replacement by high-efficiency lighting with lamps IP66 Steam high pressure sodium.
In Mexico as supplementary information to stop using the mercury vapor lamps at high pressure, since the end of the decade of the sixties (1969), was actually introduced in 1958 in power from 400 to 1000 W. Early in the decade of the seventies (1973) began to replace lighting fixtures with sodium vapor lamps on the high pressure power of 400W and then at the end of that decade began to use powers of 250W (1979).
Regarding the replacement of mercury vapor lamps in by high pressure sodium vapor lamps of high pressure, the change of system which involves having to operate the latter lamps, with their respective ballast.
A ballast mercury vapor at high pressure can not operate a sodium vapor lamp at high pressure, because the design and construction between this type of lamp is different.
A sodium vapor lamp at high pressure has a discharge tube on a cylindrical ceramic factory with aluminum oxide which requires to start downloading from a peak of the high voltage that it can only provide a Ignitor a ballast to operate lamps sodium vapor at high pressure. A mercury vapor lamp at high pressure has a discharge tube is made of quartz and for which no ignition requires no high-peak tension.

Torres Ing.Gabriel a greeting and in turn I want to point out that I agree with you about the continuity of lighting with VSAP here in my town since the last administration implemented illuminate avenues with metallic additives and practically without its downsides just got current increase in the CFE payment did go through a great discovery to citizenship but in reality they now face the problem of not grow so much in aumbrado in communities and new settlements because the turnover is too high, we are now returning to VSAP to reduce energy costs without sacrificing illumination.
I would appreciate if you send me a comparison between VSAP and LED with the current cost and VSAP and pockets of savers, since arriving in the town hall vendors offer their products to talk to people unless specified and convince unnecessary purchases.

Dear engineer, I disagree with his comparison of the use of sodium vapor lights of high pressure and metallic additives, and I assure you that the lights of AM is not suitable for street lighting. In times of rain that you see yourself on the pavement, for nothing, with no distinction AM or the lines that separate lanes, no potholes and on the other hand the use of refractors what is sometimes illuminate the nests of birds, and you Forget the street and sidewalk, in what is now called light pollution, Mexico has the best skies lit up with the lights and OV liminarias of this type, by the use of refractors, another observation in Mexico City is where it is used almost a 84% AM, by political and economic reasons, if your salts to the states 99% is not VSAP and throughout Mexico as it exposes you, I recommend that you do not see the economic side of your comments absurd if it is for Parent sales for you but you forget the security of the true user of the streets that is the pedestrian and the motorist.
carefully
Ing. Jaime Lugo Farfan
Dear Ing. Jaime Lugo Farfan:
I respect your point of view for your kind remarks and I would ask first of all, with all due respect I can tell that refers to the comments indicated that absurd, as it did not interpret its purpose and even seems a little aggressive approach to their comments.
On the other hand, just using their personal data, but it might be nice to show that company or institution in connection with the lighting belongs and what type of activities carried out, so wise for his comments.
Ing. Gabriel Torres Aguilar
Technical Consultant
I think we generalize the use of either technology is not the most appropriate, we could define them in a few words as follows; metallic additives are nice and the option The High Pressure Sodium is the most efficient or effective. Regardless of which type of lighting is used believe that the most appropriate should be able to generate more ambitious and comprehensive schemes for cities and roads and maintain efficient light where the order is more pure visual (contrast) and economy of operation and placing the most beautiful white light in areas where we have more attractive places such as resorts or symbolic buildings.
Of course that is set in a city, the hierarchy of emblematic buildings and / or roadways or transit intense ride is not easy and nothing less as in the case of this city that works in the midst of two states that obviously have ideas different and for example has the same peripheral white light (AM) in the area of Naucalpan Edo Mexico and seconds later VSAP in the district have also been seen with the naked eye with different levels of illuminance only to move in with some bridges Additives and return to the avenue with Sodium, the effect is clearly confused.
In my view both technologies have their good points and weak points and what should be important to find ways to extract maximum advantage to each of them at once and provide better lighting in cities and usually points to capture our attention which succeed attention in particular.
DISTINGUISHED ING. GABRIEL appreciate SHARE INFORMATION IS SO FULL, ALSO IF YOU HAVE ANY REQUEST luminaries of VSAP COMPARISON BETWEEN THE RELATIONSHIP WITH LED lighting.
CONGRATULATIONS FOR YOUR ARTICLE.

Regarding the comparison between luminaires for street lighting using sodium vapor lamps at high pressure and those who operate high-power LEDs, let me share the following
As an alternative energy and functional for public lighting of roadways, this is considering the gradual incorporation of the Solid State Lighting. Solid State Lighting uses electronic components directly semiconductors that convert electrical energy into light energy, which are known as LEDs (Light Emitting Diodes) - light-emitting diodes.
The LED's High Intensity Light, is being incorporated into new designs and leading-edge lighting luminaire for Public roadways, which have the following characteristics:
- Shell sink with higher temperature, constructed of cast aluminum injected at high pressure.
- Finishing the carcass of polyester powder paint applied by electrostatic process.
- Refractor plane termotemplado of clear glass.
- Joint Optical type Full Cutoff, sealed and waterproof design with the entry of solid particles and liquid (IP 65).
- Operation at ambient temperatures of - 40 to + 50 º C and Relative Humidity 0 - 95%
- 120 LED `s High Intensity Bright with unitary power of 1 Watt.
- Power Line 159 W.
- Color temperature according to the color of LED's: 2700K (White and Amber), 3500K (White) and 4000K (White and Blue).
- Performance Index of Color 80-Ra (2700K), 75 Ra (3500K) and 70 Ra (4000K).
- Initial Flow Shining 3000 lm.
- Luminous intensity of 1500 Cd.
- Input voltage of 100-240 V AC
- Operating voltage of 24 V CD
- Efficiency of 98%.
- A pole mount adapter, through entry for tube diameter from 32 to 60 mm.
- Altitude to 9 meters.
- Complies with the minimum requirements of Standard ANSI-IES RP8 "Roadway Lighting."
Currently in the Public Lighting of roadways, the Luminaires with 120 LED's High Intensity Bright, have the operational capacity to replace lamps for lighting luminaires Discharge in Gas by Low Pressure (sodium vapor) and High Pressure (Vapor Metallic sodium and additives), which are used in building height to 9 feet.
Below is a comparison between the main parameters of operation and performance of existing luminaires for street lighting of roadways sodium vapor at high pressure and a luminaire with 120 LED's High Intensity Light of 1 W each for a building height of 9 meters.
Luminaires for street lighting of roadways with a sodium vapor lamp at 250 W high pressure
1 .- Power Line: 295 W
2 .- luminaire efficiency: 85%
3 .- Color Temperature: 2100 K
4 .- Performance Index of color: 25 Ra
5 .- Average Life: 24.000 hrs
6 .- Effectiveness: 108 lm / W
7 .- Maintaining the luminous flux: 90%
8 .- Initial Luminous flux: 27,000 lm
Luminaria lighting for public roadways with 120 high power LEDs of 1 W each, 120 W
1 .- Power Line: 159 W
2 .- luminaire efficiency: 98%
3 .- Color Temperature: 2700 K
4 .- Performance Index of color: 80 Ra
5 .- Average Life: 50,000 hrs
6 .- Effectiveness: 25 lm / W
7 .- Maintaining the luminous flux: 75%
8 .- Initial Luminous flux: 3,000 lm
So additional costs should be considered initial investment, prospectación deployment in new projects, technical and economic analysis, software upgrade and replacement, financing programs, periods of recovery in investment, among others, which allow for a proper selection and implementation of the Solid State Lighting for street lighting of roadways, through the introduction of luminaires with 120 LED's High Intensity Light.

Dear Andres Trespalacios:
Regarding your wise comment on the lighting that has been in the ring peripheral part of the municipality of Naucalpan, in effect Colombians are luminaries of the mark Royalpha model Calima with additives, metal lamp 400W, which leads to an even Excessive levels of illumination in this part of the peripheral.
As regards the lighting of the ring PERIPHERAL north of the city of Naucalpan, which is itself the City of Sydney, there is a differentiation of levels of lighting fixtures with lamps using sodium vapor at high pressure into several power. It is worth mentioning that there is an interesting mix of luminaries type of head charged by various manufacturers (General Electric-M250A, Crouse Hinds LMOs, American Electric Lighting-Series 113, Holophane HOV, Lumisistemas-Cromalite among others), which even with some tranches within the City of Mexico, make the Periferico ring is a veritable museum of luminaries type head by TECHNOlOgY becomes inefficient systems that use non-cutoff.
Clearly, we must also recognize that there are sections of the ring peripherals in the City, which already have modern type of lighting system charged with cut-off lamps with steam at high pressure sodium fixtures that use American Electric Ligthing-Series 125, which meet with the levels of illumination.
In South roadways such as Pillar 3, 1 North Main Line, Circunvalacion among others, have built-head type of luminaries charged, full cutoff, IP66 model of the Canadian company Helios Lumec with sodium vapor lamps on the high pressure of 150 W and use is becoming more noticeable in Mexico City, where Leon and Guadalajara have also increased usage.

Dear Ing. Torres ..
Any comment on Section 8?
Hi Ing, Torres
Really I congratulate him for his extensive knowledge, but above all because of the ease with which shows the difference existing equipment currently used in the lighting of the entire national territory, however, for us it is somewhat alarming la introducción de los equios de Inducción Magnetica, simplemente por el echo de que la estan haciendo pasar como la gran solución a las diferentes alternativas existententes, sin considerar en ningun momento, el pesimo resultado a corto plazo (despues de su instalación), muy amablemnete lo invito a que vemos juntos la Av. Tecnoligico y podamos mutuamente comprobar como a desminuido la intensidad de los lumens de estos equipos en esta imprtante Av del municipio de Metepec Edo de México.
Como un comentario al margen, le comento que la empresa donde laboro es promotora del “Convenio de Colaboración para el Desarrollo de Proyectos de Ahorro de Energia Electrica ” convenio contemplado dentro del plan de desarrolo 2001 - 2006 y firmado el día 17 - 07 2001 por “CFE”. “CONAE”, “BANOBRAS” y “FIDE” sobre los lineamientos claros y especificos que se enmarcan en este convenio, nuestra empresa a ejecutado este proyecto en 9 estados de la Republica, y los reconocimientos por escrito que a obtenido por parte de CFE nos han servido para consolidar una imagen ante los suministradores incluyendo a Cía de Luz y Fuerza del Centro y las diferentes autoridades municipales, como una empresa seria y reposnable sobre este tema, y mas aun, porque nos hemos pegado estrictamente a las normas mexicanas, legisladas y vigentes, dentro de las cuales no se contempla los equipos de Inducción Magnetica, o al menos nosotros no ltenemos conocimientos de que alguna norma avale estos equipos.
Apreciable Ing. Torres seria usted tan amable de enviarnos o publicar algo sobre las normas mexicnas que avalen estos equipos de alumbrado publico. Sin mas por el momento y sabedor de que recibiremos todo su apoyo. Quedo de usted para cualquier duda o comentario al respecto.

En los ultimos dos anos se han desarrollado muchas necesidades para contraresta el calentamiento global y la ecologia, sin dejar atras el aumento de los derivados del petroleo.
En este momento entran las muchas ideas e inquietudes, preguntas y desconocimientos en el verdadero accionar que debemos asumir en las industrias, el gobierno y nosotros los usuarios (la gente).
EL ahorro de energia es un deber y una responsabilidad de todo el mundo para estender la vida de nuestro unica nave (Planeta Tierra) donde nos traslada ya la vez rotamos todo el mundo a la vez.
Aemas nos han permitido nacer-crecer y vivir por generacion, eso para muchos ignorante creen que existe otro planeta igual, yo se que habran en el universo algo parecido pero nunca igual que este.
LO QUE REALMENTE ME HA MOTIVADO ESCRIBIRLE ES TODOS LOS COMENTARIOS QUE HE PODIDO LEER EN ESTA PAGINA, SON DE MUCHA IMPORTANCIA PORQUE AYUDAN A ORIENTAR CON CRITERIO LAS BONDADES (BUENAS Y MALAS) DE LAS TECNOLOGIA ACTUAL Y NUEVAS QUE ESTA EN EL MERCADO EN EL AREA DE ILUMINACION.
LO IMPORTANTE DE ESTOS COMENTARIO ES PODER LOGRAR OBTENER UN PRODUCTO DE ALTA CONFIABILIDAD Y RENDIMIENTO PARA REDUCCION EL CONSUMO ENERGICO DEL MUNDO, LE FELICITO COMO HAN EXPRESADO SUS CRITERIOS SOBRE LAS LUMINARIAS Y LAS EXPERENCIAS QUE HAN VIVIDO.
YO ESTOY TRABAJANDO EN LA IMPLEMENTACION DE LA TECNOLOGIA LED Y LA DE INDUCCION MAGNETICA OBTENIENDO DIFERENTES RESULTADOS PRELIMINARES ENTRE LOS CLIENTES QUE ESTAMOS REALIZANDO PRUEBA DE AMBAS TECNOLOGIA.

Hola a todos.
Los invito a todos a consultar la página web http://www.luminnova.com , somos una empresa preocupada por el calentamiento global y pocos saben de la tecnología de focos ahorradores a 220V para apliaciones de Alumbrado Público en municipios pequeños y medianos e Industria. Hemos tenido una excelente aceptación y por supuesto también estamos incursionando en LED’s. Sin embargo, el costo de estos es aún muy alto. Mientras tanto seguiremos ofreciendo Focos Ahorradores a 220V con una solución muy buena en conjunto con una luminaria (tipo “cut off”) que aprovecha muy bien la luz del foco y también inducción magnética que es una excelente opción aunque más cara que los ahorradores.

Su valiosa opinion sobre la conveniencia de sustituir exclusivamente làmparas de VSAP de 70 y 100 wats por làmparas fluorescentes de alta potencia de 220 volts, de 65 y 85 wats respectivamente. Aun a sabiendas de que el alumbrado flourescente por norma esta prohibido en el alumbrado pùblico.
Trabajo con Gobiernos Municipales.
Tambien le agradecere Ing. un cuadro comparativo entre VSAP de 250wats con los leds correspondientes. y si la luminaria de VSAP se puede usar con leds
Atentamente
Ing. Francisco C. Flores
estimado Ing. Gabriel Torres Aguilar yo yambíen me uno a la petición de Alberto Ayala Payán por el cuadro comparativo entre vapor de sodio y las luminarias LED, tambien para alumbrado público
Estimado Ing. Francisco Cesar Flores:
Antes que otra cosa una disculpa por el retraso en poder responder a su amable inquietud.
A continuación se presenta un comparativo entre los principales parámetros de operación y desempeño de los existentes Luminarios para Alumbrado Publico de Vialidades de vapor de sodio en alta presion y un Luminario con 120 LED´s de Alta Intensidad Luminosa de 1 W cada uno ,para una altura de montaje de 9 metros.
Luminario para alumbrado publico de vialidades con una lampara de Vapor de sodio en alta presion de 250 W con reflector de aluminio y refractor prismatico de borosilicato.
1.- Potencia de linea : 295 W
2.- Eficiencia del luminario : 85%
3.- Temperatura de color: 2100 K
4.- Indice de rendimiento de color: 25 Ra
5.- Vida promedio: 24,000 hrs
6.- Eficacia :108 lm/W
7.- Mantenimiento del flujo luminoso: 90%
8.- Flujo luminoso inicial : 27,000 lm
Luminario de alumbrado publico para vialidades con 120 leds de alta potencia de 1 W cada uno,120 W sin reflector de aluminio y con refractor plano templado de vidrio
1.- Potencia de linea : 159 W
2.- Eficiencia del luminario : 98%
3.- Temperatura de color: 2700 K
4.- Indice de rendimiento de color: 80 Ra
5.- Vida promedio: 50,000 hrs
6.- Eficacia : 25 lm/W
7.- Mantenimiento del flujo luminoso: 75%
8.- Flujo luminoso inicial : 3,000 lm
En cuanto los luminarios del tipo cabeza de cobra (cobrahead); que se utilizan en el Alumbrado Publico de Vialidades , estos tienen su reflector de aluminio de alta reflectancia para eficientar el flujo luminoso que se emite por una lampara de vapor de sodio en alta presion,de hecho estos reflectores que se fabrican mediante proceso de hidroformado ,tienen un diseño especial para que el flujo luminoso sea emitido a lo largo de la vialidad,para obtener altos coeficientes de utilizacion en el lado de la calle.
Al utilizar los anteriores luminarios con diodos emisores de luz con este tipo de reflector no se aprovecha al maximo el flujo luminoso emitido total,por lo que se opta por retirar el reflector y montar los diodos emisores de luz ,con sus repectivas opticas concentradoras independientes que en conjunto permiten obtener un alto flujo luminoso hacia la vialidad,por lo que el uso de algun tipo de refractor prismatico incluso no tiene utilidad alguna,por lo cual se utilizan refractores planos transparentes de vidrio templado.

mi comentario es para conocer su opinón sobre qué tipo de lámparas son más recomendables para iluminar una carcha de basquetbol.
ing. gabriel leo con mucho interes sus comentarios tengo una duda respecto al uso de las lamparas fluorecentes en alumbrado publico pues tengo el conocimiento que por norma esta proihibido que me puede comentar al repecto
gracias

Estimado Alberto:
Tienes razon de hecho la NOM-001 de instalaciones electricas ,en su capitulo de Alumbrado Publico hace mencion que el uso de lamparas fluorescentes para tal aplicacion no se permite en Mexico.
Sin embargo como lo hice mencion en el Municipio de San Vicente Chicoloapan,Estado de Mexico; por alguna razon la oficina de Alumbrado Publico ,hizo la seleccion de lamparas fluorescentes compactas de 65 W para usos en su calles cercanas al Palacio Municipal.
Convendria conocer la posicion del fabricante Luminnova al haber especificado este tipo de lamparas fluorescentes compactas con el entendido de que por parte de la NOM-001 de instalaciones electricas su uso no esta permitido para aplicacion en Alumbrado Publico.
