Why are the brightness of LED street lights of the same power so different?

With the advancement of science and technology and the strengthening of people's awareness of energy conservation, in recent years, my country has transformed the traditional street lamps mainly based on high pressure sodium lamps into LED street lamps. LED street lights are green and environmentally friendly, save energy, consume one-third of the energy of traditional street lights under the same brightness, so they are deeply loved by people. However, the quality of LED street lamps on the market is uneven, and LED street lamps of the same power will have different brightness. So what caused this situation?
LED street lights are composed of LED chips, lenses, power supplies and drivers. The quality of chips, lenses, power supplies and drivers used by different street lamp manufacturers is different. Under the same power, the brightness of LED street lamps with high-quality components will of course be greater. Let's take the lighting to understand the factors that affect the brightness of LED street lights.


1. Lumens of the LED chip
The higher the lumens of the LED chip, the higher its luminous efficiency, and the overall brightness of the LED street light will be higher. Some street lamp manufacturers use LED chips with low lumens in order to maximize their benefits, so the brightness of LED street lamps produced by using LED chips with high lumens under the same power will definitely be lower by a grade. Our lighting generally uses high-quality Philips LED chips, with a single lumen of LM/W, so the brightness of the whole lamp is higher than that of other street lamp manufacturers.
Two, the curvature of the LED lamp bead lens
The more round the arc of the LED lamp bead lens, the more light it reflects, and the higher the brightness of the LED street lamp. And our lighting uses custom-made drop-shaped lens with high light transmittance, so the brightness is very impressive.


The above are the two main reasons why the brightness of LED street lights under the same power is so different, so everyone must pay attention to these two points when purchasing. Lighting specializes in the production of LED street lights for more than ten years, and its performance in terms of quality and brightness has always been the industry leader.
