Txheej txheem cej luam
Txawm hais tias LED (lub teeb-emitting diode) thev naus laus zis tau muaj txij li xyoo 1960, nws cov koob meej tau nce tsis ntev los no. LED teeb pom kev zoo tau loj hlob nyob rau hauv qhov chaw vim nws cov txiaj ntsig ntau, nrog rau cov nqi kho mob pheej yig, lub neej ntev, thiab kev lag luam hluav taws xob. LED illumination tuaj nyob rau hauv ob ntau yam, tab sis: flickering thiab tsis-flickering. Qhov sib txawv ntawm ob hom LED teeb pom kev zoo yuav tau tham hauv kab lus no.
Flicker LED yog dab tsi?
Thaum qhov tam sim no dhau los ntawm LED hloov pauv, qhov tshwm sim hu ua LED flicker tshwm sim. Ntau yam, zoo li tus tsav tsheb LED tsim lossis lub zog hluav taws xob zoo, tuaj yeem ua rau qhov no. Ib qho LED uas flickers yuav hloov nws lub ci ci sai sai, tejzaum nws ntau txhiab zaus hauv ib ob.
Teeb meem dab tsi ua LED Flickers ua rau?
LED flicker tuaj yeem ua rau muaj ntau yam teeb meem, nrog rau mob taub hau, qhov muag, thiab nkees, txawm tias nws yuav tsis pom qhov muag liab qab. Qhov no yog vim tias cov tsos mob no tuaj yeem tshwm sim los ntawm flicker qhov cuam tshuam ntawm tib neeg lub hlwb kev ua haujlwm tsis tu ncua.
Tsis tas li ntawd, ntau yam khoom siv hluav taws xob, xws li khoos phis tawj, TV, thiab koob yees duab, yuav ntsib teeb meem kev ua haujlwm vim LED flicker. Qhov no yog vim qhov flicker yuav cuam tshuam rau cov duab hauv ntau txoj hauv kev, xws li tsim cov nyhuv banding.
Hauv qab no yog flicker test daim duab qhia:
Tsis-Flickering LED Teeb pom kev zoo: Nws yog dab tsi?
Cias muab, LED teeb pom kev zoo uas tsis flicker yog hu ua non-flickering LED teeb pom kev zoo. Hom LED teeb pom kev zoo no yog qhov zoo tshaj plaws rau ntau yam kev siv vim nws yog tsim los tsim lub teeb pom kev ruaj khov thiab txhim khu kev qha.
Dab tsi zoo Ua Tsis-Flickering LED teeb pom kev zoo xaiv?
Tsis-flickering LED teeb pom kev zoo muaj ntau qhov zoo. Ua ntej tshaj plaws, nws yog qhov tsawg dua taxing ntawm lub qhov muag thiab tuaj yeem txo qhov hnyav thiab qhov muag. Rau cov neeg uas siv sijhawm ntau nyob rau pem hauv ntej ntawm lub computer lossis lwm yam khoom siv hluav taws xob, qhov no yog qhov tseem ceeb heev.
Tsis tas li ntawd, cov teeb pom kev tsis zoo ntawm LED ua haujlwm zoo nrog lwm yam khoom siv hluav taws xob xws li TV thiab koob yees duab. Raws li qhov tshwm sim, koj tuaj yeem siv tsis-flickering LED teeb yam tsis muaj kev txhawj xeeb txog kev cuam tshuam lossis cuam tshuam.
Hauv qab no yog daim duab qhia tsis-flicker test diagram:
Hauv kev xaus
Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb ntawm LED teeb pom kev zoo uas flickers thiab tsis-flickering LED teeb pom kev zoo. Tsis-flickering LED teeb pom kev zoo yog npaj los tsim kom muaj lub teeb pom kev ruaj khov thiab tsis sib xws, thaum LED flicker tuaj yeem ua rau muaj ntau yam teeb meem, suav nrog qhov muag pom thiab cuam tshuam nrog cov khoom siv hluav taws xob. Xaiv qhov tsim nyog LED teeb pom kev zoo rau koj cov kev xav tau yog qhov tseem ceeb vim tias LED teeb pom kev zoo txuas ntxiv kom muaj koob meej. Koj tuaj yeem siv tag nrho cov txiaj ntsig ntawm LED teeb pom kev zoo yam tsis muaj qhov tsis zoo los ntawm kev xaiv cov teeb pom kev tsis zoo ntawm LED.
