Kugereranya ubuzima bw'itara rya LED hamwe na LM-80 na TM-21
LED Ubuzima hamwe niterambere ryubu
Ubuzima bwa LED nyayo itanga urumuri igice cyagenwe nubushyuhe bwo gukora bwa LED (ubushyuhe bwa LED ihuza) kuburyo iyo ubushyuhe buke burigihe ubuzima bwa LED. Ibindi bintu nyamukuru bigira ingaruka kumibereho ya LED bifitanye isano numuyoboro wimbere nkuko byavuzwe ugereranije nubucyo bwa LED. Mubisanzwe, imbere yimbere ntabwo arikibazo gikomeye kuko abakora LED bazagaragaza urwego rukora neza, nubwo urwego rwo hejuru rusaba gushushanya neza. Niba LED ikora cyane ishyushye yo hepfo yimbere irashobora kongera ubuzima bwa chip ya LED, nubwo mubisanzwe niba chip ya LED ikomeza kuba nziza ugereranije nigishushanyo mbonera cyiza (munsi ya 85 ° C), igihe cyubuzima ntikizahinduka cyane.
L70 Icyizere cyo kubaho
Amatara ya LED ntakunze gutsindwa bikabije nkaho hari abayibanjirije. Iyo ababikora bagaragaje ubuzima bwa LED cyangwa ubuzima bwamatara yose ya LED mumasaha baba berekeje kumakuru ya L70 yerekana igereranya ryukuri ryerekana igihe cyafashwe kugirango LED itakaza 30% yumucyo cyangwa igabanuke kugeza kuri 70% yumucyo wumwimerere, L70. Ibi mubisanzwe byerekanwe mumasaha 30.000 kugeza 40.000 kandi bakunze kwita Lumen kubungabunga cyangwa guta agaciro kwa Lumen.
Nyamara, urumuri rwa LED ntiruzabura gutungurwa ahubwo ruzakomeza gutanga urumuri neza kurenza ubuzima bwa L70, nubwo rumuri ruto kugeza igihe urumuri ruzaba rucye kuburyo budashobora gukoreshwa. Ikigereranyo cyerekana ko urumuri rwa LED ruzamara amasaha 100.000 cyangwa arenga mbere yuko ruzimya. Mubikorwa byinshi "urumuri rwubuzima"! Kubwibyo, ubuzima bwa LED mubusanzwe ni burebure bihagije kandi ntabwo bihinduka ikibazo usibye mugihe cyamasaha menshi yo gukora cyangwa ubushyuhe bwo hejuru bwo gukora, nkuko byavuzwe bishobora guturuka kubishushanyo mbonera.
Kubara L70 Icyizere cyo kubaho ukoresheje LM-80 yamakuru yikizamini na TM-21 Extrapolation
Kubara L70 LED yubuzima ni ibintu byoroshye ariko bitwara igihe ukoresheje amakuru yikizamini cya LM-80 bisaba umucyo cyangwa lumens kwipimisha ingero nyinshi za LED kubushyuhe butatu butandukanye, 55 ° C, 85 ° C hamwe nundi, kandi kumenya igihombo mumucyo mwinshi kumwanya munini hejuru yamasaha 6000 kugeza 8000. Ikizamini gishobora gufata hafi umwaka umwe wo gukora.
Nkuko byaganiriweho, iyo tumaze kugira amakuru yikizamini cya LM-80 kuri chip ya LED dushobora noneho gutandukana dukoresheje uburyo bwa TM-21 aribwo buryo bukoreshwa cyane na formula yo kumenya ubuzima bwa L70 mumasaha ya chip ya LED mugihe igabanutse kugera kuri 70 % y'ibisohoka.
