1. High reliability: LED products are mainly composed of LED chips and power supplies, heat dissipation shells, and control circuits. led driver The quality of the LED power supply directly affects the quality of the product. Especially LED street light products, because they are installed at high altitude, maintenance is inconvenient and expensive.
2. High efficiency: LED is an energy-saving product, and the driving power supply should also meet the requirements of energy-saving. In particular, the structure of the power supply installed in the lamp is particularly important. Because the luminous efficiency of LED decreases with the increase of LED temperature. The efficiency of the power supply is high, its power loss is small, and the heat generated in the lamp is small, which reduces the temperature rise of the lamp. It is beneficial to delay the light decay of the LED.
3. Constant current drive mode: In order to match the VI characteristics of the LED, the LED power supply must use the constant current drive mode.
4. Working environment: Due to the difference in the environment of various places, it is necessary to focus on the environment of the workplace where the LED lamps work, such as temperature, humidity, installation location, etc.
