introduction High-power white LEDs are a new generation of semiconductor light sources that are non-linear loads. Since the load characteristics cannot be described in a wide range and accurately, the light-emitting characteristics of the LED cannot be effectively controlled by the voltage type driver. When the load voltage has a slight fluctuation, it can cause a large change in the current, so that the brightness changes greatly. If the load voltage fluctuates too much, the LED may burn out....
Q: There is a warehouse with a length of 12 meters, a height of 6 meters and a height of 2 meters. Now it has to be raised from 0 degrees to 50 degrees. How to configure with a heat sink and a fan? A: First of all, depending on whether you are rising from 0 degrees to 50 degrees, there is no time requirement; the heat sink provides heat energy, and the fan acts as air circulation heat exchange.
