We have a driver chip product, SN3352, which has applied for a global patent and has temperature compensation function. The peripheral components are very simple. You only need to connect a thermistor to one pin of the IC to detect the LED temperature and control it. Current, and the curve of the control current is adjustable, which can be adjusted down quickly or slowly. When the temperature returns to the normal level, the current will automatically rise. It can also be connected to a photosensitizer, and the LED will automatically adjust as the ambient brightness changes. Brightness. As mentioned above, LEDs will still generate heat after limiting the current. Anything will also generate heat after limiting the current. As long as its efficiency is not 100%, heating is inevitable, but when the current is reduced, the amount of heat will be reduced. This is what we The desired effect. Moreover, the reduced current will not be too much, and will decrease slowly. The human eye has a logarithmic curve relationship with light. If the current decreases by such a small amount, the human eye will not be able to detect it.
