Kev soj ntsuam ntxaws ntxaws ntawm cov cuab yeej siv hauv LED vaj huam sib luag teeb
LED panel lights have many performance characteristics such as easy adjustment of the light size, very strong dimmable performance, vibration resistance, high luminous efficiency, small size and thinness, and energy saving, environmental protection, long service life, safety and reliability. Now we will Three technical details are analyzed from the technology used in LED panel lights:
Ua ntej: qhov kev tsim kho qhov muag thib ob ntawm LED vaj huam sib luag teeb pom kev zoo Cov ntsiab lus tseem ceeb ntawm kev tsim kho qhov muag yog tsim los ntawm peb yam:
1. Raws li qhov yuav tsum tau ua ntawm cov khoom siv teeb pom kev zoo thiab cov luminous flux, txiav txim siab cov duab ntawm cov khoom siv kho qhov muag, tus naj npawb ntawm LEDs thiab qhov loj ntawm lub hwj chim;
2. Combine several LED light-emitting tubes into a "secondary light source" of a point light source, a ring light source or a surface light source, and calculate the lighting optical system according to the combined secondary light source;
3. The light distribution control of each LED tube on the "secondary light source" that constitutes the design of the lighting optical system is very important.
Thib ob: Txhim kho cov xim rendering Performance index ntawm LED vaj huam sib luag teeb pom kev zoo
Tam sim no, lub teeb dawb LEDs feem ntau siv lub teeb xiav -emitting LEDs rau superimpose yellow light-emitting yttrium aluminium garnet (YAG) phosphors zoo siab los ntawm lub teeb xiav los ua kom pom lub teeb dawb. Qhov rhiab heev ntawm tib neeg lub qhov muag rau chromatic aberration yog ntau dua li qhov siv lub teeb. Rau kev teeb pom kev zoo, cov xim rendering ntawm lub teeb ci yog feem ntau tseem ceeb tshaj qhov ua tau zoo ntawm luminous. Yog li ntawd, ntxiv qhov tsim nyog ntawm cov xim liab - emitting phosphor hmoov thiab tswj lub siab luminous efficiency yog ib qho teeb meem tseem ceeb hauv LED teeb pom kev zoo.
Thib peb: kev tswj cua sov ntawm LED vaj huam sib luag teeb pom kev zoo
Feem ntau hais lus, LED yog lub teeb txias, vim tias lub teeb -emitting txoj cai ntawm LED yog txheej txheem kev uas electrons ncaj qha emit photons los ntawm recombination yam tsis muaj cua sov. Txawm li cas los xij, vim muaj Joule tshav kub, LED kuj muaj cua sov thaum nws tawm lub teeb. LED yog qhov kub thiab txias -sensitive ntaus ntawv. Thaum qhov kub nce siab, nws lub zog poob qis heev. Yog li ntawd, cov lus piav qhia txog kev tsim vaj tsev thiab kev tsim cov tshuab hluav taws xob cua sov kuj yog cov teeb meem uas yuav tsum tau ntsib hauv kev siv cov teeb ci LED.
Vim hais tias kev quab yuam cua txias feem ntau tsis xav tau hauv qhov chaw teeb pom kev zoo, cov dab dej kub thiab lwm txoj hauv kev los txhim kho lub ntuj convection txias yog ua lub luag haujlwm tseem ceeb hauv LED vaj huam sib luag teeb pom kev zoo thiab lub teeb pom kev zoo thaum lub zog hluav taws xob nce. Cov teeb pom kev zoo ntawm siab- zoo LED vaj huam sib luag teeb tsim los ntawm cov kws tshaj lij LED vaj huam sib luag teeb pom kev lag luam yooj yim dua rau kev tswj, thiab cov khoom lag luam muaj kev cuam tshuam ntau dua thiab txhim khu kev qha, yog li lawv ib txwm nyiam los ntawm cov neeg siv khoom thiab nqa cov txiaj ntsig tseem ceeb rau kev ua haujlwm. .
