Comparison of LED garden lights and traditional street lights (high pressure sodium lights)

With the widespread use of high-power LEDs in lighting decoration and lighting, power-type LED drivers are becoming more and more important. It will be possible to use high-power LED lighting for road lighting. Road lighting is the lamp with the longest use time and the most power consumption. The use of LED lamps in street lamps will greatly reduce the shortage of electricity in cities and save national energy. There are many domestic manufacturers of LED street lights, and the performance of their products varies greatly. Here only take the LED street lamp produced by our company as an example. Compare with the traditional street lamp (high pressure sodium lamp).

Ci-dessous, nous commenterons les performances et l'économie des lampadaires à LED et des lampadaires traditionnels.

Comparaison des performances des startups

Le projecteur LED démarre instantanément, tandis qu'il faut plus de 10 minutes à la lampe au sodium haute pression pour commencer à atteindre une luminosité normale. Pendant ce temps, la lampe au sodium haute pression consomme beaucoup d'énergie, tandis que le projecteur LED consomme une énergie normale.

Through the control circuit (such as Hangzhou Zhonggang Digital), the input voltage of the LED flood light can be between 90 volts and 265 volts without affecting the LED lights. The high-pressure sodium lamp cannot start when the input voltage is less than 185V, and the power increases by 12% when the input voltage exceeds 245V. In this way, high-pressure sodium lamps have higher requirements for power supply lines. The LED has no effect.

Comparison of color rendering

The color rendering of high-pressure sodium lamps can only reach 20 to 30, while LED floodlights can reach more than 85. Compared with traditional lamp lighting, the driver can better recognize obstacles in the road and the surrounding environment of the road, and reduce the occurrence of traffic accidents.

The level of color rendering directly reflects the scotopic difference (S/P) of human eyes to light. Therefore, the luminous flux emitted by the high pressure sodium lamp must be multiplied by a correction value (0.64) to be the light perceived by the human eye strength. The luminous flux emitted by the LED lamp must be multiplied by a correction value (1.60) to be the intensity perceived by the human eye.

Color temperature range

The color temperature range of high-pressure sodium lamps is 2000 to 2500, while the color temperature range of LED street lamps is 2700k to 9000k. If the color temperature is low, it gives people a warm feeling in winter, but it gives people a hot feeling in summer. If the color temperature is high, it will give people a cold feeling in winter and a cool feeling in summer.

Generally, people spend more time in the evening in the summer, but less time in the evening in winter. There is more hot weather than cold weather in the year. Therefore, it is better to use white light with a high color temperature for road lighting.

 Luminous decay

The luminous decay of LED floodlights has a lot to do with the radiators of LED lamps. Some manufacturers do better. For example, our company adopts the technology of "Multilayer Compound Heat Dissipation System" independently developed and obtained the national invention patent. The radiator is independently developed and molded, and the developed radiator makes it fit well with the lamp piece to achieve the best heat dissipation effect.

According to the current data, its light decay is less than 3% in 10,000 hours! The light decay of the high-pressure sodium lamp is generally greater than 25% in 2000 hours.

Comparison of lamp efficiency

L'efficacité énergétique des projecteurs LED de notre entreprise peut atteindre 88 %. Alors que le rendement des lampes au sodium haute pression ne peut atteindre que 70 %. Par exemple, la consommation électrique d’un projecteur LED de 120 watts est de 138 watts, tandis que celle d’une lampe au sodium haute pression de 120 watts est de 156 watts.

Comparaison de la protection de l'environnement

Le projecteur LED ne contient pas de mercure, pas de rayonnement ultraviolet et sa basse température de fonctionnement réduit efficacement les émissions de chaleur.

Puisqu’il économise de l’électricité, il économise du charbon pour la production d’électricité et utilise moins de charbon pour la production d’électricité. Ainsi, des économies d’émissions de dioxyde de carbone ! La lampe au sodium haute pression contient du mercure et des rayons ultraviolets. De plus, il émet beaucoup de chaleur, consomme de l'électricité, gaspille du charbon et émet beaucoup de dioxyde de carbone lorsqu'il travaille !

De plus, le facteur de puissance de la LED est supérieur à 0,99 et celui de la lampe au sodium haute pression est d'environ 0,44. De cette façon, la pollution de la LED sur le réseau électrique est très faible, et la pollution de la lampe au sodium haute pression sur le réseau électrique est grande ! Les lampes LED n'ont pas de pollution stroboscopique et lumineuse, tandis que les lampes au sodium haute pression ont une pollution stroboscopique et lumineuse évidente.

Utilisation efficace de la lumière

Effective light utilization Rate Due to the characteristics of LED light source similar to point light source, it emits directional light to the illuminated object. There is basically no waste of light, so it has a very high light utilization rate, which can reach more than 92%. However, because the high-pressure sodium lamp emits on all sides, the light is source blocks part of the light itself and has a large luminous point. It is difficult to make optical design, and the efficiency of the lamp is not high, and the output.

Le spot lumineux ne chevauchera pas la surface éclairante efficace requise et ne gaspillera pas une partie de la source lumineuse. Par conséquent, elle est projetée sur la surface de l’objet éclairé à travers le réflecteur de la lampe, et une partie de la lumière sera perdue au milieu. Par conséquent, le taux d’utilisation efficace de la lumière des lampes traditionnelles est de 55 à 60 %.

Source and development:

Road lighting is an important part of urban lighting. Traditional street lamps are often used. High-pressure sodium lamps emit 360 degrees, and the shortcomings of large light loss have caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. So, with the rapid growth of the national economy, the contradiction between my country's energy supply and demand has become increasingly prominent, and there has been a serious shortage of power supply. Energy conservation is an urgent problem to be solved. Therefore, the development of a new type of high-efficiency, energy-saving, long-life, high color rendering index, environmentally friendly LED street lamps is of great significance to the energy saving of urban lighting.

Road lighting is closely related to people’s production and life. With the acceleration of my country’s urbanization process, LED street lights have gradually adopted advantages such as directional lighting, low power consumption, good driving characteristics, fast response speed, high earthquake resistance, long service life, and environmental protection. Into people’s vision, it has become the world's most energy-saving light source of a new generation with the advantage of replacing traditional light sources. Therefore, LED street lights will become the best choice for road lighting energy-saving transformation.

LED street lights refer to street lights made with LED light sources, which have the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. They are of great significance to energy saving in urban lighting.

3. The LED has reached 110-130lm/W, and there is still a lot of room for development, the theoretical value reaches 360lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall luminous efficiency of LED street lamps is stronger than that of high-pressure sodium lamps; (The overall luminous efficiency is theoretical, in fact, the luminous efficiency of high-pressure sodium lamps above 250W is higher than that of LED lamps. ).
4. The light color rendering of LED street lamps is much higher than that of high pressure sodium lamps. The color rendering index of high pressure sodium lamps is only about 23, while the color rendering index of LED street lamps is above 75. From the perspective of visual psychology, you can achieve the same brightness. It is more than 20% lower than high pressure sodium lamp.
5. La décroissance de la lumière est faible, la décroissance de la lumière en un an est inférieure à 3 % et elle répond toujours aux exigences routières après 10 ans d'utilisation, tandis que la lampe au sodium à haute pression a une décroissance importante, qui a diminué de plus de 30 %. % dans environ un an. Par conséquent, la conception de la puissance du lampadaire LED peut être inférieure à celle des lampes au sodium haute pression.

Avantages supplémentaires

1. 1. The LED street lamp has an automatic control energy-saving device, which can achieve the greatest possible reduction in power and energy-saving under the condition of meeting the lighting requirements at different times. It can realize computer dimming, time period control, light control, temperature control, automatic inspection, and other humanized functions.

   5. Excellent contrôle de la dissipation thermique : la température en été est contrôlée en dessous de 45 degrés, et la dissipation thermique passive est adoptée, et la dissipation thermique en été est insuffisante.
   6. Qualité fiable : toutes les alimentations de circuit utilisent des composants de haute qualité et chaque LED dispose d'une protection individuelle contre les surintensités, vous n'avez donc pas besoin de vous soucier des dommages.
   7. Couleur de la lumière uniforme : vous n'avez pas besoin d'ajouter de lentille. Et il n'y a aucun compromis sur la couleur de lumière uniforme afin d'améliorer la luminosité, afin de garantir une couleur de lumière uniforme sans ouverture.
   8. La LED ne contient pas de mercure métallique nocif et ne nuira pas à l'environnement lorsqu'elle est mise au rebut.

Combining the above principles, the energy-saving effect is remarkable, and it can save more than 60% of electricity instead of high-pressure sodium lamps.

Faible coût de maintenance : par rapport aux lampadaires traditionnels, le coût de maintenance des lampadaires à LED est extrêmement faible. Après comparaison, tous les coûts des intrants peuvent être récupérés en moins de 6 ans.

Désavantage

1. 1. Une seule LED a une faible puissance. Vous avez besoin de plusieurs connexions parallèles pour obtenir une puissance élevée,
   2. Faible rendu des couleurs. La couleur affichée sous l'éclairage LED n'est pas aussi vraie que celle d'une lampe à incandescence. Ceci doit être analysé à partir de la distribution spectrale, ce qui constitue un problème technique.
   3. Zone de lumière. En raison des défauts dans le processus de fabrication de la LED blanche elle-même et de l'erreur de correspondance avec la coupelle ou la lentille réfléchissante, il est facile de provoquer le problème du « cercle jaune ».
   4. Problème d’uniformité de l’éclairage des LED. Si la conception optique secondaire n’est pas réalisée. L'éclairage de la LED est relativement concentré. La conception optique secondaire doit donc être réalisée pour que la carte de répartition de l'intensité lumineuse ressemble à une chauve-souris.
   5. The light decay of LED. Compared with low-power LEDs, high-power LED street lights to have much better light decay. However, low-power LEDs emit very little heat. Heat dissipation cannot solve the high-power LED. Thus, the brightness significantly decreases after heating, so you cannot increase power. The largest Spark LED street light sold in the market is 360W.

Shopping points:

Luminous efficiency

Technology is becoming more and more mature, thus the high-power LED light sources already meet the needs of general street lights.  In addition, the luminous efficiency of the general high-pressure sodium lamp is 100LM/W, and the high-power LED is 50-60LM/W. It can reach 80LM/W with foreign LED chips. The higher the luminous efficiency, the better the energy-saving effect. In addition, this is also the choice One of the most important indicators of LED street lights. However, there is no clear stipulation in the LED standard, so you must carefully confirm when purchasing LED street lights.

Light decay

And some businesses, in order to reduce costs, use hundreds of low-power LEDs of 0.5W. However, the light decay of this low-power LED is very serious, and its light decay to 80% has a life span of only 1000 hours. Therefore, as a street lamp that needs to be used for a long time, it is absolutely not allowed to use such low-power LEDs. Using high-power LEDs (generally more than 30W) will have a much better light decay.

Self-respect

Due to the high technical content and complex composition of LED street lamps, the weight of some high-power lamp holders will far exceed that of ordinary high-pressure sodium lamps, so the requirements for corresponding supporting materials are higher.

However, some LED street lamp manufacturers have tried their best to reduce the self-weight of the LED lamp holder, from about 30 kg per lamp holder to more than 10 kg, and the weight reduction has a further downward trend.

Heat dissipation

Because LED is a semiconductor component, so the temperature has an impact on it and reduces to 30% of the initial luminous flux, it will lose its illumination meaning, that is, the end of life.

In theory, the life of high-power LED street lights is 30,000 to 50,000 hours, but The important premise is good heat dissipation. It is worth mentioning that domestic manufacturers have adopted the world's leading needle-shaped heat dissipation technology.

Exigence de compétences :

The technology is becoming more and more mature, therefore the efficiency of the light source has reached more than 100lm/W, which makes the energy-saving transformation of urban street lighting possible. LED street lamps, especially high-power LED street lamps, are impacting the traditional street lamp market at a rapid pace.

As the name implies, high-power LED street lights are street lights with a power greater than 30 watts and using a new type of LED semiconductor light source. Therefore, The standard is generally the uniformity of road illuminance, in line with road illuminance. (The actual 1/2 center spot reaches 25LUX, the 1/4 center light intensity reaches 15LUX, the lowest light intensity at 16 meters is 4LUX, and the overlap light intensity is about 6LUX. It refers to the LED street light that uses solar silicon panels as the power supply.

Standard

1. Le taux de conversion de la lumière est de 17 % (l'énergie solaire par mètre carré est de 1 000 W et l'efficacité d'utilisation réelle est de 170 W).
2. Also, the street lamp lens material in the market is an improved optical material, with a transmittance of ≥93%, a temperature resistance of -38 to +90 degrees, and an anti-UV and yellowing rate of 30,000 hours without change.
3. LED street lamp, in addition, mainly used for the lens of LED street lamp, the spot is rectangular, the material is PMMA optical material, the transmittance is ≥93%, the temperature resistance is -38-+90 degrees, and the anti-UV yellowing rate is unchanged for 30,000 hours. Wait,
4. L'éclairement moyen d'uniformité de l'éclairement de la surface routière est de 0,48 et le rapport des spots est de 1:2.
5. Rencontrez l'éclairage routier. (Le point central réel 1/2 atteint 25LUX, l'intensité lumineuse 1/4 centrale atteint 15LUX, l'intensité lumineuse la plus faible à 16 mètres est de 4LUX et l'intensité lumineuse qui se chevauche est d'environ 6LUX.
6. It also has very good application prospects in new urban lighting. Dimming depth, and color and other characteristics will not change due to dimming.
7. S'adapter à l'humidité : ≤95.

Despite the rapid development of LED street lights, the standard of LED street lights is relatively lagging behind. Globally, there are not all LED street lamp standards, such as European standards for LED street lamps. In fact, the standards for LED street lamps in various regions are not the same in terms of indicators.

LED street lamps must meet the requirements of the sales area in terms of standards. Therefore, bidding for LED street lamp projects requires in-depth study of local LED street lamp standards. Only in this way will it be fierce. Occupy a place in the market competition.
