High luminous efficiency: LEDs lawv tus kheej muaj luminous efficiency tshaj 130 lm / W, yog li tag nrho cov luminous efficiency ntawm LED siv lead ua qab nthab teeb muaj peev xwm ncav cuag 100 lm / W. Ntxiv mus, qhov no efficiency yog nce txhua xyoo; Nws tau kwv yees tias los ntawm 2020, qhov ua tau zoo ntawm LEDs yuav ncav cuag 240 lm / W.
High luminous efficiency txhais tau hais tias lub zog txuag. Raws li kev ntsuas tiag tiag, 8W LED tuaj yeem hloov tau 32W siv lead ua qab nthab teeb, txuag ntau tshaj plaub npaug ntawm kev siv hluav taws xob. Ntev lifespan: LEDs muaj lifespan ntawm 100,000 teev. Thaum ua rau cov teeb pom kev zoo, qhov kev lees paub dav dav dav dav yog tsawg kawg 30,000 teev, nrog siab - cov khoom siv tau zoo txog 50,000 teev. Yog li ntawd, lub neej ntev ntawm LED qab nthab teeb yog feem ntau ntawm 50,000 thiab 70,000 teev.
Mercury-dawb, tsis muaj hluav taws xob ultraviolet, tsis muaj teeb meem lub teeb: tuaj yeem muab ntau yam xim kub raws li xav tau, feem ntau 2550-3700ºK thiab 4700-7000ºK. Tsis muaj iav Cheebtsam, cuam tshuam thiab kev co resistant, yooj yim rau thauj. Tsis xav tau aluminium kub dab dej, tus nqi qis, thiab lub teeb yuag.
