style="text-indent:25px">比紅光波長(zhǎng)長(zhǎng)的光為紅外光。現(xiàn)在已有紅外、紅、黃、綠及藍(lán)光發(fā)光二極管，但其中藍(lán)光二極管成本、價(jià)格很高, 使用不普遍。LED的調(diào)光控制傳統(tǒng)上，LED的調(diào)光是利用一個(gè)DC信號(hào)或?yàn)V液PWM對(duì)LED中的正向電流進(jìn)行調(diào)節(jié)來(lái)完成的。減小LED電流將起到調(diào)節(jié)LED光輸出強(qiáng)度的作用，然而，正向電流的變化也會(huì)改變LED的彩色,因?yàn)長(zhǎng)ED的色度會(huì)隨著電流的變化而變化。許多應(yīng)用(例如汽車(chē)和LCD TV背光照明)都不能允許LED發(fā)生任何的色彩漂移。在這些應(yīng)用中，由于周?chē)h(huán)境中存在不同的光線(xiàn)變化，而且人眼對(duì)于光強(qiáng)的微小變化都很敏感，因此寬范圍調(diào)光是必需的。</p><p style="text-indent:25px">LED三防燈性能優(yōu)點(diǎn) 1、節(jié)能:同等功率的LED燈耗電*為白熾燈的10%，比日光燈還要節(jié)能，不發(fā)燙,防油,防塵.2、壽命長(zhǎng):LED燈珠的可以工作5萬(wàn)小時(shí)，比日光燈和白熾燈都長(zhǎng)。3、可調(diào)光:以前的調(diào)光器一直是針對(duì)白熾燈的，白熾燈調(diào)暗時(shí)光線(xiàn).發(fā)紅;很難見(jiàn)到日光燈調(diào)光器，這是調(diào)光技術(shù)很多年沒(méi)有發(fā)展的主要原因;現(xiàn)在LED又可以調(diào)光了，并且無(wú)論是亮還是暗光都是同樣的顏**溫基本不變)，這一點(diǎn)明顯優(yōu)于白熾燈的調(diào)光。4可頻繁開(kāi)關(guān): LED的壽命是按點(diǎn)亮?xí)r算的，即便每秒鐘開(kāi)關(guān)數(shù)千次也不影響LED壽命，在裝飾等需要頻繁亮滅的場(chǎng)合，LED燈有***優(yōu)勢(shì)。在點(diǎn)間距不變的前提下，LED器件尺寸增大，能夠增加顯示面積，減少顆粒感。</p><div style="width:100%;text-align: center;"><img
