With the advancement of science and technology and the awareness of people saving energy, in recent years, China has transformed traditional street lamps with high-pressure sodium lamps into LED street lamps. LED street lights are green and energy-saving, and the energy consumed under the same brightness is one-third of that of traditional street lamps, so it is very popular among people. However, the quality of LED street lights on the market is currently uneven, and LED street lights of the same power may have different brightness. So what is the reason for this happening?
LED street lights are made up of LED chips, lenses, power supplies and drives. The quality of chips, lenses, power supplies and drives used by different streetlight manufacturers is also different. Under the same power, the brightness of LED street lights with high quality components will certainly be greater. Below, we will have a deep understanding of the factors affecting the brightness of LED street lights.
First, the lumen count of the LED chip
The higher the lumen count of the LED chip, the higher its light efficiency and the higher the brightness of the overall LED street light. Some street lamp manufacturers use LED chips with low lumens in order to maximize profits. Then the brightness of LED street lights produced by LED chips with high lumens will be lower than the same level. Our thousand-degree lighting generally uses high-quality Philips LED chips, and the single lumen is 130LM/W, so the brightness of the whole lamp is higher than other street lamp manufacturers.
Second, the arc of the LED lamp lens
The rounder the arc of the LED lamp bead, the more light it reflects, and the brightness of the LED street light will be higher. And our thousand-degree lighting uses a custom-made drop-type lens, which has a high light transmittance, so the brightness is very impressive.
