Kev ua haujlwm kub thiab qhov tseem ceeb ntawm LED teeb yog raws li hauv qab no:
1. Kev ua haujlwm kub ntau
Pas LED teeb pom kev zoo fixtures:
Environmental kub: Nws feem ntau yog tsim los ua haujlwm ruaj khov ntawm-20℃~ +40 degree, thiab qee cov khoom lag luam qib tuaj yeem txuas ntxiv mus-40℃~ +60℃.
Chip hlws ris kub (qhov tseem ceeb parameter):
Qhov sib txuas kub (Tj) ntawm kev lag luam dav dav LEDs yuav tsum tau tswj ntawm<85 ℃ (such as in home lighting).
Lub zog LEDs siab (xws li tsheb thiab teeb pom kev zoo sab nraum zoov) tuaj yeem tso cai tsawg dua lossis sib npaug li 120 degree, tab sis lawv lub neej yuav txo qis nrog qhov kub thiab txias.
Ib puag ncig huab cua:
Tsis tshua muaj kub ib puag ncig (xws li -30 degree): qhov pib yuav qeeb, tab sis nws feem ntau ua haujlwm.
High temperature environment (>50 degree): yuav tsum muaj kev txhawb nqa kev tsim hluav taws xob, txwv tsis pub qhov ci yuav txo qis thiab lub neej yuav luv.
2. Qhov cuam tshuam ntawm qhov kub thiab txias ntawm LED
Lifespan: Rau txhua txhua 10℃nce nyob rau hauv junction kub, lub lifespan yuav txo los ntawm 30% mus rau 50% (xws li los ntawm 25℃mus rau 85 degree, lub lifespan yuav txo los ntawm 50000 teev mus rau 20000 teev).
Lub teeb pom kev zoo: Lub teeb tso zis txo qis ntawm qhov kub thiab txias (xws li ci ci tuaj yeem txo los ntawm 15% mus rau 20% ntawm 85℃piv rau 25 degree).
Xim kub: kub kub yuav ua rau xim kub hloov (xws li sov txias dawb lub teeb).
3. Cov qauv tsim qauv kub dissipation
Kub dab dej kub: feem ntau yog 20℃~ 30℃siab tshaj qhov kub ntawm qhov chaw (xws li thaum lub ambient kub yog 25 degree, qhov kub dab dej kub yog li 50 degree).
Kev nyab xeeb kov kub: Qhov kub thiab txias ntawm cov khoom siv hauv tsev yog feem ntau tswj ntawm<60 ℃ (to avoid burns).
4. Qhov kub thiab txias yuav tsum muaj rau cov xwm txheej sib txawv
Daim ntawv thov hom Kev ua haujlwm kub ntau yam tshwj xeeb yuav tsum tau ua
Lub teeb pom kev hauv tsev 0℃~ 40℃Tsawg suab nrov, qis kub nce
Sab nraum zoov teeb pom kev zoo -30℃~ 50℃Waterproof, dustproof, siab kub dissipation
Lub teeb lub tsheb -40℃~ 80 degree, tiv taus kev co thiab ceev cua sov dissipation
Muaj teeb pom kev zoo -20℃~ 60℃anti-corrosion, siab stability
5. Cov neeg siv ceev faj
Tsis txhob siab - qhov kub thiab txias ib puag ncig: embedding LED teeb nyob rau hauv cov ntaub ntawv rwb thaiv tsev yuav ua rau overheating.
Tsis tu ncua ntxuav lub tshuab hluav taws xob: Cov plua plav pov tseg tuaj yeem txo cov cua sov kom zoo.
Xaiv lub siab- zoo tsav fais fab mov: overheating ntawm lub hwj huam mov yog ib qho ua rau LED malfunction.
Rau cov ntaub ntawv meej, nws raug nquahu kom xa mus rau cov ntaub ntawv ntawm cov khoom tshwj xeeb, nrog rau kev tsom mus rau qhov tsis xws li qhov kub thiab txias (Tj) thiab thermal kuj (R θ j-a). rausiab ua haujlwm kub 60 degree, koj tuaj yeem sab laj rauhttp://www.benweilight.com
