The LED module is the most important component of the LED lamp. The biggest shortcoming of the existing LED module is that it cannot be changed. Once the product is formed, the shape and power cannot be adjusted. The brightness can only be adjusted by the brightness adjustment module provided in the circuit, that is, the brightness cannot be greatly increased. The need to increase the brightness can only be achieved by increasing the number of LED lights. Multiple LED lights are not connected separately, or are electrically connected together by exposed wires, and cannot be used as a unified whole. In addition, most of the LED market currently uses low-voltage LEDs. With the maturity of AC LED and DC high-voltage LED technology, AC LED and DC high-voltage LED technology will be widely used. Different types of LEDs have different driving voltage modes and LED rows. Different cloth methods, if you make a different PCB board and different lens cover for each type of LED, it is not only troublesome, but also will cause waste of materials.
