How do LED lamp realize the lighting function? It mainly exerts its light effect by converting electrical energy into luminous energy. During this conversion process, part of the electrical energy will also be converted into heat energy, and when the power of the LED lamp is greater, the heat energy generated will also increase. In order to extend the service life of LED lamp and reduce safety hazards, NTC thermistor is required as temperature control and temperature monitoring component to ensure that operating temperature of LED lamps is within the specified range.
NTC thermistor fully demonstrates its extreme sensitivity to temperature in the operation process and heat dissipation process of LED lamp. In the working process of LED lamp, NTC thermistor, as a temperature monitoring module, with the assistance of the temperature processing module, compares the temperature data obtained in real time with the preset upper and lower limit values of the operating temperature of the LED lamp to ensure that the LED lamp works within the conventional temperature range. In the process of heat dissipation of LED lamp, NTC thermistor, as a temperature control module, helps heat dissipation circuit of LED lamp to control the working temperature in real time, thereby improving the heat dissipation performance of LED lamp, avoiding light decay problem caused by poor heat dissipation, and even causing damage to the lamp body.
In summary, NTC thermistor plays its excellent over-temperature protection during the working process of LED lamp. Considering that most of the internal circuit module structure of LED lamp on the market is developing towards miniaturization, the selection of NTC thermistor is generally the CT series SMD type NTC thermistor of EXSENSE Electronics Technology Co., Ltd., because of its small size and leadless structure, which can save installation space. Moreover, the SMD type NTC thermistor produced by EXSENSE Electronics also achieves long-term high reliability due to the improvement of the slicing process, which is able to help LED lamp reduce their own failure rate effectively.
