NTC thermistor for smart temperature sensing LED lights

　　LED lighting systems have the characteristics of low power consumption and long life, so LED lights are lighting electronics that can be seen everywhere in our lives, and intelligent temperature-sensing LEDs are more convenient for people's lives.

　　The semiconductor PN junction, which is the light-emitting layer in the LED device, generates heat. This temperature is called the bonding temperature. As the current flowing through the LED increases, the brightness will increase, and the heat generation will also increase, so that the junction temperature will increase, and the life will be shortened. In addition, when the junction temperature is too low, the luminous efficiency will decrease, and the brightness will decrease. For this reason, in order to maximize the efficiency of the LED, it is necessary to operate at an optimal temperature.

　　The NTC thermistor suitable for intelligent temperature-sensing LED lamps produced by Minchuang Electronics is the following MF52 epoxy head temperature-measuring NTC thermistor

　　By embedding the NTC thermistor into the circuit and thermally coupling it with the LED, it can work as a simple temperature protection circuit. If there is a deviation from the optimum operating temperature, it will be manifested in the form of the resistance change of the NTC thermistor, and the current flowing through the LED will be compensated at this time. Ultimately, the LED power consumption will be reduced and the lifespan will be extended.
