Yam twg yuav cuam tshuam rau lub teeb pom kev zoo ntawm LED teeb qhov chaw Module

Cov ntaub ntawv tshawb pom los ntawm ib lub teeb dawb LED ntawm lub rooj tsav tsheb laus, thiab cov ntaub ntawv tshawb pom thaum sib sau ua ke LED teeb dawb rau hauv lub teeb aging yog twv yuav raug hu me ntsis. Qhov loj ntawm qhov sib txawv no nyob ntawm qhov ntsuas hluav taws xob thiab qhov tsim ntawm lub teeb thaum lub teeb ci LED module, nrog rau ib puag ncig siv los ntawm cov teeb. Ua ntej ntawm tag nrho cov, hom LED teeb hlaws xaiv dab tsi. Tsis tas li ntawd xwb. Qhov zoo ntawm LED teeb hlaws tuaj yeem hais tias yog qhov tseem ceeb heev. Piv txwv li, tib yam yog sawv cev los ntawm cov nti ntawm cov nti ntawm cov nti 14mil, thiab LED teeb hlaws dai ntawm cov pos hniav hauv qab thiab cov kua nplaum dawb thiab cov kua nplaum ua los ntawm cov epoxy resin zoo tib yam, uas ci ib qho ib puag ncig ntawm 30. qib. Tom qab ntau txhiab teev, cov ntaub ntawv attenuated yog 70% ntawm qhov muag pom; Yog tias D hom D qis-decaying kua nplaum yog encapsulated, nyob rau hauv tib lub aging ib puag ncig, lub 1,000-teev lub teeb lwj yog 45%; , 1,000-teev lub teeb lwj yog 12%; yog tias qeb B yog encapsulated nyob rau hauv cov kua nplaum uas tsis tshua muaj, nyob rau hauv tib lub aging ib puag ncig, phav phav teev ntawm lub teeb lwj ntawm -3%; Yog hais tias Class A yog cov kua nplaum qis qis, nyob rau tib lub sijhawm laus, ntau txhiab teev ntawm lub teeb nyob rau hauv tib qhov kev laus, ntau txhiab teev ntawm lub teeb nyob rau hauv tib qhov chaw laus, ntau txhiab teev ntawm lub teeb nyob rau hauv tib lub hnub nyoog ib puag ncig, ntau txhiab teev. teev ntawm lub teeb nyob rau hauv tib lub aging ib puag ncig, ntau txhiab teev ntawm lub teeb rau ntau txhiab teev ntawm lub teeb. Dab tsi yog qhov txawv ntawm kev ntim khoom sib txawv? Qhov laj thawj tseem ceeb yog vim li cas LED teeb qhov chaw module nti ntshai ntawm tshav kub. Qee zaus rhuab ntau tshaj 100 degrees hauv lub sijhawm luv luv, nws tsis nruj, kuv ntshai tias nws yuav kub hnyiab tau ntev, uas yog kev puas tsuaj loj rau LED nti. Feem ntau hais lus, thermal conductivity ntawm epoxy resins zoo tib yam yog me me. Yog li ntawd, thaum LED chips yog teeb, LED chips yuav tsum emit kub, thiab zoo tib yam epoxy resin thermal conductivity yog txwv. Thaum qhov kub ntawm LED bracket yog 45 degrees, qhov nruab nrab kub ntawm nti chaw nyob rau hauv lub teeb dawb LED yuav tshaj 80 degrees. Qhov kub ntawm lub LED yog tiag tiag 80 degrees, yog li thaum LED nti ua haujlwm ntawm qhov kub thiab txias, nws raug kev txom nyem heev, uas ua rau cov laus ntawm cov teeb pom kev zoo ntawm LED. Thaum LED nti ua haujlwm, qhov nruab nrab qhov kub thiab txias ua rau kub siab ntawm 100 degrees. Nws tuaj yeem siv tam sim ntawd tus pin sawv rau lub tshav kub kom txo tau cov cua sov, yog li txo qhov kev puas tsuaj rau nws. Yog li ntawd, thaum qhov kub ntawm LED teeb hlaws dai yog 60 degrees, qhov kub ntawm nws qhov chaw nti yuav tsuas yog 61 degrees. Raws li tuaj yeem pom los ntawm cov ntaub ntawv saum toj no, LED teeb hlaws hlaws uas xaiv cov txheej txheem ntim dab tsi yog xaiv, thiab kev txiav txim siab lub teeb ntawm LED teeb ncaj qha txiav txim siab lub teeb kev txiav txim siab ntawm LED teeb. Qhov thib ob, qhov chaw ua haujlwm kub ntawm LED teeb qhov chaw module. Raws li cov ntaub ntawv ntawm ib lub teeb ci LED, yog tias lub teeb ci LED tsuas muaj ib qho teeb pom kev ua haujlwm, thiab tib lub sijhawm, qhov kub thiab txias nws nyob ntawm 30 degrees, ces qhov ntsuas kub ntawm ib lub teeb ci LED tsis tshaj. 45 degrees thaum ua haujlwm ntawm 45 degrees. Lub sijhawm no, lub neej ntawm LED no yuav zoo tagnrho. Yog hais tias muaj 100 LED teeb qhov chaw ntawm kev ua hauj lwm tib lub sij hawm, lub ncua sij hawm ntawm lawv tsuas yog 11.4 hli, ces lub bracket kub ntawm LED teeb qhov chaw nyob ib ncig ntawm lub teeb pawg yuav tsis pub tshaj 45 degrees, tab sis cov LEDs nyob rau hauv nruab nrab ntawm. lub teeb pawg yuav tsis Lub teeb qhov chaw yuav ncav cuag 65 degrees kub. Lub sijhawm no, lub teeb ci LED yog qhov kev sim. Tom qab ntawd, cov teeb pom kev zoo ntawm LED uas tau sib sau ua ke hauv nruab nrab yuav theoretically sai dua, thiab LED teeb qhov chaw nyob ib ncig ntawm lub teeb pawg yuav qeeb dua. Tab sis yog tias LED teeb hlaws hlaws ntau tshaj 25 hli sib nrug, ces cov calories lawv hloov mus yuav tsis sib sau ntau heev. Nyob rau lub sijhawm no, qhov kub ntawm txhua LED teeb hlaws yuav tsum tsawg dua 50 degrees, uas yog qhov zoo dua rau kev ua haujlwm ntawm LED. Yog hais tias ib puag ncig ntawm lub teeb ci LED module nyob rau hauv qhov chaw txias, qhov nruab nrab kub ntawm tag nrho lub xyoo yuav tsuas yog hais txog 15 degrees los yog me dua, uas yog ntev dua rau LEDs.
