How to choose the right LED driver wisely
梦幻岛
How to choose a suitable led driver wisely is the concern of every engineer. Here are some ideas for your reference.
According to the power consumption characteristics of the power grid, the requirements of LED characteristics and related LED products, three general principles should be followed when considering the selection of LED driving power:
1. According to the characteristics of LED current and voltage, it is ideal to use constant current drive. It can avoid the current fluctuation caused by the change of LED forward voltage, and at the same time, the constant current can stabilize the brightness of the LED.
2. In addition, the LED luminous flux is inversely proportional to the temperature, so the heating of the power supply should be minimized and a well-designed cooling system should be used. Thereby reducing the working temperature of the LED.
3. In order to ensure the overall life of the LED, the temperature of the LED must be controlled within a certain range.
