LED yog ib tug semiconductor diode nrog lub neej ntev heev. Thaum lub luminous flux lwj mus rau 30 feem pua, nws lub neej ncua mus txog 30 000h. Lub neej ntawm hlau halide teeb yog 6000-12000h, thiab lub neej ntawm high-pressure sodium teeb yog 12000h.
Lub hauv paus qauv ntawm lub teeb ci LED teeb yog tias ib daim ntawm cov khoom siv hluav taws xob hluav taws xob semiconductor tau muab tso rau ntawm lub txee coj, thiab tom qab ntawd kaw nrog epoxy resin los tiv thaiv cov tub ntxhais hauv cov hlau, thiab muaj kev ua haujlwm zoo seismic.
Cov xim rendering Performance index ntawm dawb LED vaj teeb yog zoo dua li ntawm high pressure sodium teeb. Nyob rau theem nruab nrab tsis pom kev, tib neeg lub qhov muag tuaj yeem paub qhov txawv ntawm qhov yooj yim dua nyob rau hauv ib puag ncig xim kub ntau dua li qhov kub thiab txias ib puag ncig. Cov xim rendering ntawm dawb LED vaj teeb kuj tseem zoo dua li ntawm high-pressure sodium teeb. Cov xim rendering Performance index ntawm lub siab siab sodium teeb yog tsuas yog hais txog 20, thaum lub teeb dawb LED teeb lub teeb tuaj yeem ncav cuag 70 txog 90.
LED vaj huam sib luag teeb tuaj yeem ua tiav txoj haujlwm dimming zoo meej. Vim muaj kev ua haujlwm loj, nws lub teeb tso zis yog proportional rau qhov ua haujlwm tam sim no, yog li nws tuaj yeem txo qhov tam sim no kom dimming. Tsis tas li ntawd, txij li kev hloov pauv tsis tu ncua tsis ua rau muaj kev puas tsuaj ntau rau nws, qhov dimming ntawm LED vaj teeb kuj tuaj yeem ua tiav los ntawm kev hloov pauv ntawm pulse dav, uas yog, qhov siv zog ntawm LED tuaj yeem kho tau zoo los ntawm kev kho lub luag haujlwm ntawm lub voj voog. voltage thiab kev khiav hauj lwm zaus.
Nyob rau hauv lub optical system ntawm lub teeb, lub luminous flux poob ntawm LED lub teeb qhov chaw yog me me. Qhov sib txawv ntawm cov teeb pom kev zoo ib txwm muaj, LED qhov chaw teeb pom kev yog ib nrab ntawm qhov chaw teeb pom kev zoo: cov teeb hluav taws xob sodium siab lossis hlau halide teeb yog lub teeb ci uas tawm hauv txhua qhov chaw. Lub teeb tawm ntawm ib nrab ntawm qhov chaw yuav tsum tau hloov pauv 180 "mus rau lwm qhov ib nrab ntawm qhov chaw. Thaum tso siab rau cov reflectors Thaum nws los txog rau kev ua tiav, qhov nqus ntawm lub teeb los ntawm lub reflector thiab qhov thaiv ntawm lub teeb qhov chaw nws tus kheej yog inevitable. Txawm li cas los xij, nrog kev siv cov teeb pom kev zoo ntawm LED, yuav tsis muaj qhov poob ntawm qhov no, thiab qhov kev siv lub teeb yog siab dua.
Lub teeb ci LED tsis muaj cov hlau tsis zoo mercury thiab yuav tsis ua mob rau ib puag ncig tom qab muab pov tseg.
Hnub ci LED vaj teeb muaj ntau yam ntxwv ntawm ob lub hnub ci thiab semiconductor LEDs. Nws yog tsim los ntawm cov teeb pom kev zoo ntawm LED, lub hnub ci vaj huam sib luag, cov roj teeb hnub ci, cov roj teeb ntsuab tsis muaj kev saib xyuas, cov tswj hwm, lub teeb ncej thiab teeb ntxoov ntxoo. Kev ywj pheej fais fab mov thaum lub sij hawm installation, yog li tsis tas yuav embed cables ua ntej, yog li txuag peev hauv transformers, fais fab faib khoom thiab cables. Thiab nws yog ib puag ncig tus phooj ywg, zoo nkauj, yooj yim rau nruab thiab nyab xeeb.
