zui近以來，led日光燈成為zui早進(jìn)入室內(nèi)的LED燈具之一，因?yàn)樗鄬?duì)于熒光燈來說具有很多優(yōu)點(diǎn)。一．優(yōu)點(diǎn) 相對(duì)于熒光燈來說，led日光燈具有**優(yōu)點(diǎn):1.發(fā)光效率高:熒光燈的發(fā)光效率大約是55-80 lm/W (Philips公司T8熒光燈的發(fā)光效率為72lm/W)，而LED的發(fā)光效率在100 lm/W以上，zui近Cree公司的XLampXP-G的發(fā)光效率已經(jīng)到130流明/W，而且以后還會(huì)不斷提升。二者之差現(xiàn)在已經(jīng)將近一倍。而以后有可能達(dá)到3倍以上。2.燈具效率高:燈具的效率主要是指有效光效，因?yàn)闊晒鉄羰?60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。天津飛利浦led投光燈燈具</p><p
