Why same power LED street light brightness difference so big?

- -

with the progress of science and technology and people's energy saving consciousness to strengthen, in recent years, our country has will be given priority to with high pressure sodium lamp tradition of street lamp into the LED street light. LED street light green environmental protection, energy saving, consumption of energy under the same brightness is a third of the traditional street lamp, so was deeply loved by people. LED street light quality on the market at present, however, the same power of LED street lamp brightness is not the same would happen. Then what causes this to happen?

the LED street lamp is made of the LED chip, lens, such as power supply and drive components. Different lamps manufacturer adopts chip, lens, power supply and drive quality is different also, under the same power, choose a good quality parts of LED street lamp brightness, of course, will be more bigger. Below by lighting with insight into the factors influencing the LED street lamp brightness. A

the number of lumens, LED chip LED chip, the higher the number of lumens, so it had higher photosynthetic efficiency, overall LED street lamp brightness will be higher. Some lamps manufacturer in order to pursue benefit maximization using low lumens count LED chip, so under the same power with a high number of lumens LED chip to produce the LED street lamp brightness is bound to low a class. Our lighting generally USES the high quality of philips LED chips, single lumen for LM/W, so the whole lamp brightness is higher than other street light manufacturer.

2, LED lights, the radian of lens

the radian of the round LED lamp bead lens, it reflected the more light, the brightness of the LED street lamp will be higher. And our lighting using custom type water lens, high light transmittance, so the brightness is very considerable.

that is under the same power of LED street lamp brightness difference so big of the two main reasons, therefore everybody is when the choose and buy must pay attention to both. Lighting professional production LED lights for more than ten years, in terms of quality and brightness of performance has always been the leader of the industry, please rest assured the choose and buy,
