First of all, let’s understand the multi-chip combination light source used by China Flood Light Manufacturers. According to the current situation of China Flood Light Factory, the power of a single LED chip on the market is generally between 1 and 5W, and the luminous flux output is only a few hundred lumens. In order for LEDs to be used in general lighting on a large scale, the luminous flux of LED street light sources must reach thousands or even tens of thousands of lumens. Such a high light output cannot be achieved by a single chip. In order to meet such a high light output requirement, a combined light source with multiple LED chips (usually 1W) is currently used at home and abroad.

1. The production process of LED street lamps is cumbersome, with low production efficiency and low reliability.

2. The design of lamps is limited by the number and arrangement of single LEDs, so it is difficult to balance the aesthetic appearance and guaranteed performance of the produced lamps.

3. The secondary light distribution design of the lamp is complicated, it is difficult to meet the requirements of various lighting designs, and it will reduce the light efficiency of the lamp.

4. When dozens of single-chip LEDs are arranged in the same lamp, the photoelectric performance parameters of each LED chip must be consistent, otherwise the photoelectric performance and usability of the lamp will be greatly reduced.

5. Blind spots and dark spots are prone to occur due to local failures during use, which increases maintenance costs.
