LPR恆溫技術(shù)是一種無(wú)外置開(kāi)關(guān)驅動(dòng)的新型的led驅動(dòng)技術(shù)。 該技術(shù)主要採用三種可靠性元素構(gòu )成：led光源、PPTC熱敏電阻、R門(mén)限電阻。該技術(shù)直接把驅動(dòng)及控制作為電路的一部分，有效地結(jié)合，實(shí)現(xiàn)了對(duì)led工作環(huán)境溫度的調(diào)控。保障了可靠地運(yùn)行、長(zhǎng)壽命。減小產(chǎn)品體積的同時(shí)也大大降低了成本。
LPR constant temperature technology is a new type of led driver technology without external switch driver, which mainly usesthree high reliable elements: led light source, the PPTC thermistor and R threshold resistance. It directly makes the drive and control system be part of the circuit, and combines effectively to control temperature of working environment. This technologyensures reliable operation and long service life. Reducing products volume, at the same time it also declines the cost greatly.
