Temperature Detection of LED Flashing Substrate Based on NTC Thermistor 3

4. By calculating the temperature of the LED chip based on the temperature of the heat sink, real-time monitoring of the temperature of the LED chip can be achieved.

5. If the temperature of the LED chip rises to a certain level, the temperature of the LED chip can be controlled by controlling the power of the LED or adjusting the heat dissipation capacity of the heat sink. diode

4、 Conclusion

This article introduces a temperature detection scheme for LED flash substrates based on NTC thermistors. This solution can achieve real-time monitoring of the temperature of LED chips, which helps to protect the lifespan and brightness of LED chips. In practical applications, the parameters of NTC thermistor and the design scheme of measurement circuit need to be selected according to the specific situation of LED flash substrate.diode
