As the preheating and softly-starting component of the electronic ballasts and energy-saving lamps, the intelligent PTCR without power consumption can greatly increase the light switching time and operating time. Meanwhile, it can overcome the disadvantage of temperature-rising after preheating and starting of the electronic ballasts and energy-saving lamps, therefore improve the amount of the flowing light and the lighting efficiency of the lamps. It can be considered as another breakthrough revolution of green illumination electric applianc.

工作原理：

智能型功率PTC熱敏電阻器是由電壓開關(guān)元件與PTC熱敏電阻器組合而成的具有復(fù)合功能的智能型元件，在燈、電子鎮(zhèn)流器上起啟動作用。利用燈管啟輝電壓高、工作電壓低的特點，選用工作電壓高于燈管工作電壓、低于燈管啟輝電壓的電壓開關(guān)元件，在燈管啟輝時電壓開關(guān)元件導(dǎo)通，電流通過PTC元件使其阻值產(chǎn)生劇烈變化而使燈管點亮，燈管點亮后電壓回落到正常工作電壓，此時電壓開關(guān)元件關(guān)斷有電流通過，該智能型元件消耗電能，功率的目的。

優(yōu)點：

智能型功率PTC熱敏電阻器的優(yōu)點是在燈正常工作時，不消耗電能使燈、電子鎮(zhèn)流器的效率更高；

由于在工作中PTC元件無電流通過因此不會產(chǎn)生熱量，有利于燈、電子鎮(zhèn)流器的穩(wěn)定工作，壽命更長。
