Do you know how to choose high quality lamp?
- Choose high luminous efficient lamp
LED lighting technology becoming mature, high power LED light source has can meet the general street lamp luminous flux as needed. Commonly used high power LED is 80 to 120 lm/W, with the best LED chip and lens can reach 180lm/W, the higher luminous efficiency, energy saving effect means the better, which is to choose one of the most important indicator of LED street light. Leds, however, does not have explicitly stipulated in the standard, so must be carefully confirmed when purchasing LED street light.
- Choose high power led chips
Now some businessmen in order to reduce costs, with hundreds of small power LED 0.5 W. However, this kind of small power LED light failure is very serious, its light failure and 80% of life is only 1000 hours. As the need for long-term use, so the LED street light is absolutely not allowed the use of this kind of small power LED, high power leds,(generally refers to more than 30 w), the light failure will be much better.
- Choose lighter lamp
LED street light due to the complexity of high technical content, composition and so on reasons, some high power lamp holder will weigh far more than ordinary high pressure sodium lamp, so the support for the corresponding material requirements are higher. However, some LED street light manufacturer has as much as possible to reduce the weight of the LED lamp holder, from the original single lamp holder about 10 kilograms, dropped more than 50 kilograms, weight loss and the trend of decline further.
- Choose good Heat dissipation street lamp
LED for semiconductor components, the wafer is affected by temperature and reduced to 30% of the initial luminous flux, will lose the meaning of lighting, or put an end to the life, the life of the high powerLED street light in theory 3-50000 hours, but the premise is have good heat resistance. It is worth mentioning that domestic has adopted the world’s leading manufacturer of acicular heat dissipation technology.
According to the above conditions, we recommend to you our patented lamps,it is a perfect lamp.
