Chii chinonzi LED light attenuation?
LED mwenje attenuation inoreva kusimba kwechiedza che LED ichave yakaderera pane yepakutanga mwenje kusimba mushure memwenje, uye chikamu chezasi ndiko kudzikamisa kwechiedza che LED. Kazhinji, vagadziri vepakeji ye LED vanoedza pasi pemamiriro emurabhoritari (panguva yakajairwa tembiricha ye25 ° C), uye vachiramba vachivhenekera iyo LED neDC simba re20MA kwemaawa 1000 kuenzanisa kusimba kwechiedza pamberi uye mushure mekunge mwenje wabatidzwa. .
Kuverengera nzira yekudzikisira chiedza
N-awa chiedza attenuation = 1- (N-awa chiedza flux / 0-awa chiedza flux)
Chiedza chekudzivirira ma LEDs anogadzirwa nemakambani akasiyana-siyana akasiyana, uye ma LED ane simba-akakwirira achavawo nekuderedza chiedza, uye ane hukama hwakananga nekushisa, izvo zvinonyanya kuenderana nechip, phosphor uye teknolojia yekuisa. Iyo inopenya inopenya ye LEDs (kusanganisira luminous flux attenuation, kushanduka kwemavara, nezvimwewo) chiyero chemhando ye LED, uye zvakare inyaya yekunetseka kukuru kune vazhinji vanogadzira LED uye vashandisi ve LED.
Zvinoenderana netsanangudzo yehupenyu hwezvigadzirwa zve LED muindasitiri ye LED, hupenyu hwe LED inguva yekuwedzera yekushanda kubva pakukosha kwekutanga kusvika pakunyangarika kwechiedza kusvika ku50% yekukosha kwepakutanga. Zvinoreva kuti kana iyo LED inosvika pahupenyu hwayo hunobatsira, iyo LED icharamba iripo. Zvisinei, pasi pechiedza, kana chiedza chinobuda chakaderedzwa ne50%, hapana chiedza chinobvumirwa. Kazhinji, kudzoreredzwa kwechiedza chemukati memba hakugone kudarika 20%, uye mwenje wekudzivirira wemwenje wekunze haugone kuve wakakura kupfuura 30%.
