Kev nkag siab yuam kev hauv kev siv cov infrared LEDs hauv cov koob yees duab kev ruaj ntseg
1. Qhov tseem ceeb ntawm cov cua kub dissipation yog qhov tsis saib xyuas: peb feem ntau siv cov dab dej kub me me dhau los yog tsis muaj dab tsi ua kom sov. Nws yog ib qho tseem ceeb kom paub: Tsis zoo cua sov dissipation yuav ua rau siab khiav hauj lwm kub ntawm nti, uas ua rau infrared wavelength drift thiab txo photoelectric conversion efficiency. Qhov siab wavelength, tshaj 850nm, ua rau lub koob yees duab CCD muaj lub teeb pom kev tsis zoo, uas yog, qhov pom kev hmo ntuj ua rau tsis zoo. Tsawg photoelectric conversion efficiency txhais tau tias tsis txaus brightness. Feem ntau ob peb xees ntawm lub dab dej kub yuav ua rau muaj txiaj ntsig loj ntawm cov tub rog me uas ua rau muaj txiaj ntsig zoo.
2. Tsis yog tes kov los ntsuas qhov ntsuas kub: tib neeg feem ntau xav tsis thoob los ntawm lawv tus kheej, vim tias lawv tsis tuaj yeem tiv taus tsawg dua 2-3 vib nas this thaum lawv muab lawv txhais tes rau ntawm lub plhaub (los yog lub dab dej kub) tshaj 44 degrees Celsius, yog li Kuv xav tias "kub dhau", qhov tseeb, qhov kub tsis siab thiab yuav tsis ua mob rau lub cev ua haujlwm ntawm cov khoom siv hluav taws xob txhua. Tsis tas li ntawd, qhov kub ntawm lub tsev nyob (los yog lub dab dej kub), qhov zoo dua qhov cua sov dissipation. "Lub zog yog indestructible"---Xav txog: Lub plhaub (los yog lub dab dej kub) tsis kub. Qhov no "kub" mus qhov twg? Lub tshav kub nyob twj ywm ntawm cov nti thiab tsis tuaj yeem coj tawm, uas ua rau cov nti ua haujlwm nyob rau hauv qhov kub thiab txias, thiab qhov pom kev hmo ntuj tsis zoo, lub teeb tawg loj, thiab lub neej luv luv.
3. Xav tias lub nti loj yuav tsum "ci" dua li cov nti me: Yog li ntawd, LEDs uas yuav tsum tau loj - cov chips loj yog feem ntau tsis pom kev. Koj paub: qhov ci ntsa iab nyob ntawm qhov tam sim no, siv tau npaum li cas tam sim no? Nws nyob ntawm kev ua cov cua kub dissipation, uas yog: tshav kub dissipation txiav txim qhov tam sim no thiab yog li qhov ci, tsis yog qhov loj ntawm cov nti txiav txim siab qhov ci. Nyob rau hauv txoj kev xav, tsis hais qhov loj ntawm tib hom chips, yog tias tam sim no thiab voltage yog tib yam (tib lub zog), lub tshav kub generated yuav zoo ib yam. Lo lus nug yog: Ntau npaum li cas cheeb tsam yog tib lub tshav kub kis? Tshaj tawm ntawm lub qhov pinhole- qhov loj me thiab lub xib teg- qhov loj me, qhov nyuaj ntawm cov cua kub dissipation txawv heev. Nyob rau hauv cov nqe lus ntawm tshav kub dissipation, txhua lub tuam txhab muaj ntau yam technologies, khoom siv, thiab cov ntaub ntawv kub dissipation. Yog li ntawd, txhua lub tuam txhab muaj peev xwm sib txawv nrog tib "kub" nyob rau hauv ntau npaum li cas.
Piv txwv li: yog tias koj muab 1.2A tam sim no ntawm Epistar 28mil nti thiab 42mil nti, qhov hluav taws xob yog me ntsis tib yam (li 1.7V), yog li lub zog me ntsis zoo ib yam (txog 2W), thiab tau kawg cov cua sov tsim tau zoo ib yam. Qhov teeb meem yog: Nws yooj yim dua rau dissipate 2W cua sov ntawm thaj tsam ntawm 42mil nti, tab sis nws nyuaj dua rau disperse nws ntawm 28mil nti. Siv cov nplaum nplaum rau "bond die" txoj kev ntim khoom, nws cov thermal kuj feem ntau yog 20 degree -30 degree / W, thiab siv eutectic technology ntim, nws cov thermal kuj feem ntau yog 6 degree -10 degree / W. Nws qhia tau hais tias cov nyhuv thermal dissipation yog txawv kiag li. Cov tsav tsheb tam sim no tuaj yeem siv los ntawm ob qho tib si saum toj no txawv heev, thiab qhov ci ntsa iab kuj txawv heev.
Tau kawg, kev siv cov thev naus laus zis thev naus laus zis los xaiv cov ntim ntim me me thiab kev tsav tsheb siab tam sim no kuj txwv. Yog hais tias qhov saum toj no 2W cua sov tso rau ntawm thaj tsam ntawm 10mil nti, txawm tias nws tau ntim nrog cov txheej txheem eutectic, nws yog tam sim no nyuaj rau smoothly thiab tag nrho cov Export. Saib rau yav tom ntej, nrog cov cuab yeej siv hluav taws xob zoo dua thiab cov khoom siv, nws tuaj yeem ua tiav ntau dua infrared LEDs nrog cov chips me me thiab cov nqi qis dua, tab sis nrog tib lub teeb pom kev zoo hmo ntuj.
To sum up: the night vision effect of a large-size chip may not be stronger than that of a small-size chip, depending on the quality of the heat dissipation process. Therefore, the packaging technology of the eutectic process is one of the important means for the improvement of cost performance at present, and it should be the future trend.
