Comparaison du projecteur LED et du lampadaire traditionnel (lampe sodium haute pression)

*La consommation énergétique des projecteurs LED et la consommation énergétique des lampadaires LED sont les mêmes à même puissance. Ce qui suit cite les données de comparaison de la consommation d'énergie des lampadaires à LED.

With the widespread use of high-power LEDs in lighting decoration and lighting, power-type LED drivers become more and more important. Thus, it is 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. Also, 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 LED lamp manufacturers, and the performance of their products varies greatly. Here only take the LED flood light produced by our company as an example. Contrast with traditional flood light (high pressure sodium lamp).

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

Comparison of performance comparison

Comparison of service life The traditional high-pressure sodium lamps with flood light sources currently circulating in the market have a shorter lifespan due to quality and technical problems, generally less than 6000 hours. The LED street lamp of Hangzhou Zhonggang Digital Technology Co., Ltd. The service life is more than 50,000 hours, which is equivalent to more than 8 times the life of the best high-pressure sodium lamps in circulation today.

That is to say, the high-pressure sodium lamp is replaced more than 8 times. On the contrary, you will have to replace the LED flood light only once.  Thus, the cost of replacing the light source will not survive. The maintenance cost and the many inconveniences caused by it are the most obvious contrast. (Because of the special purpose of the street lamp, it is difficult to replace, it takes a certain amount of manpower and machine resources to complete the operation). LED flood light has no effect on the number of switches, no However, the high-pressure sodium lamp has a certain limit on the number of switching times.

Generally, it can only be switched on and off for 4000 to 5000 times, and the service life is over. The LED street lamp can be switched on and off for any number of times and at the end of its service life. There is no blackening phenomenon. The high-pressure sodium lamp is switched on and off for 1000 times or after 1000 hours of use, the lamp tube is obviously black, and the light efficiency is reduced by 16%. Our company adopts imported luminous body packaged by Nichia chip in Japan, and the quality is undoubtedly the top product on the market.

Comparison of start-up performance.

The LED flood light starts instantly, while it takes more than 10 minutes for the high-pressure sodium lamp to start to reach normal brightness. During this time, the high-pressure sodium lamp consumes a lot of power, while the LED flood light consumes normal power. 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 20-30, while LED floodlights can reach more than 85. Compared with traditional lighting fixtures, the driver can better identify obstacles in the road and the surrounding environment of the road, and reduce the occurrence of traffic accidents. Also, 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 feel cold in winter and cool in summer. Generally, people spend more time in the evening in summer, but less time in the evening in winter, and there are 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! In general, the light decay of the high-pressure sodium lamp is more than 25% in 2000 hours.

Comparison of lamp efficiency

The power efficiency of our company's LED floodlights can reach 88%, while the efficiency of high-pressure sodium lamps can only reach 70%. For example, the entire lamp power consumption of a 120 watt LED flood light is 138 watts, while the entire lamp power consumption of a 120 watt high pressure sodium lamp is 156 watts.

Comparaison de la protection de l'environnement

LED flood light does not contain mercury, no ultraviolet radiation, and its low working temperature effectively reduces heat emission. Because it saves electricity, it saves coal for power generation and uses less coal for power generation, thereby saving carbon dioxide emissions! The high-pressure sodium lamp contains mercury and ultraviolet radiation, so it emits a lot of heat, consumes electricity, wastes coal, and emits a lot of carbon dioxide!

The LED power factor is greater than 0.99, and the power factor of the high-pressure sodium lamp is about 0.44. So, in this way, the LED pollutes the power grid very little, while the high-pressure sodium lamp pollutes the power grid very much! LED lamps have no stroboscopic and light pollution, while high-pressure sodium lamps have obvious stroboscopic and light pollution.

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, part of the light is blocked by the light source 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 The light spot will not reconcile with the required effective irradiation surface and waste part of the light source. Therefore, it is projected to the surface of the illuminated object through the reflector of the lamp, and part of the light will be lost in the middle. Therefore, the effective light utilization rate of traditional lamps is 55~60%

 Présentation détaillée :

avantage

  1. Ses propres caractéristiques : lumière unidirectionnelle, pas de diffusion de la lumière, assurant l'efficacité lumineuse.
  2. The LED street lamp has a unique secondary optical design, which irradiates the light of the LED street lamp to the area that needs to be illuminated, and further improves the light efficiency to achieve the purpose of energy saving.
  3. The LED has reached 130-170lm/W, and there is still a lot of room for development, with a theoretical value of 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;
  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, the same brightness can be achieved. 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.
  6. Le lampadaire LED dispose d'un dispositif d'économie d'énergie à contrôle automatique, qui peut obtenir la plus grande réduction possible de puissance et d'économie d'énergie à condition de répondre aux exigences d'éclairage à différents moments. Il peut réaliser une gradation par ordinateur, un contrôle de période, un contrôle de la lumière, un contrôle de la température, une inspection automatique et d'autres fonctions humanisées.
Avantages supplémentaires
  1. Longue durée de vie : il peut être utilisé pendant plus de 50 000 heures et offre une assurance qualité de trois ans. L'inconvénient est que la durée de vie de l'alimentation électrique ne peut être garantie.
  2. Efficacité lumineuse élevée : en utilisant des puces ≥100LM, il peut économiser plus de 75 % d'énergie par rapport aux lampes au sodium haute pression traditionnelles.
  3. Installation facile : pas besoin d'ajouter des câbles enterrés, pas de redresseurs, etc., connectez-vous directement au poteau de la lampe ou emboîtez la source de lumière dans le boîtier de la lampe d'origine.
  4. 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.
  5. 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.
  6. Uniform light color: No lens is added, and uniform light color is not sacrificed to improve brightness, so as to ensure uniform light color without aperture.
  7. La LED ne contient pas de mercure métallique nocif et ne nuira pas à l'environnement lorsqu'elle est mise au rebut.

En combinant les principes ci-dessus, l'effet d'économie d'énergie est remarquable et permet d'économiser plus de 60 % d'électricité au lieu des lampes au sodium haute pression.

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. A single LED has low power. In order to obtain high power, multiple parallel connections are required.
  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. LED illumination uniformity problem. If the secondary optical design is not carried out, the illumination of the LED is relatively concentrated, so the secondary optical design must be carried out to make the light intensity distribution map look like a bat.
  5. The light decay of LED. Compared with low-power LEDs, high-power LED street lights have much better light decay. However, low-power LEDs emit very little heat. The high-power LED has a problem that cannot be solved by heat dissipation, and the brightness will be significantly reduced after heating, so the power cannot be increased.

  6. Il présente de très bonnes perspectives d’application dans le nouvel éclairage urbain. La profondeur de gradation, la couleur et les autres caractéristiques ne changeront pas en raison de la gradation.
  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.
