LED Teeb Test Standard thiab IP Qib Test

LED (Lub Teeb Emitting Diode), lub teeb -emitting diode, yog ib qho khoom siv -state semiconductor ntaus ntawv uas tuaj yeem hloov hluav taws xob rau hauv lub teeb pom kev. Nws tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub teeb. Lub plawv ntawm LED yog semiconductor wafer. Ib qho kawg ntawm lub wafer txuas nrog lub bracket, ib qho kawg yog qhov tsis zoo electrode, thiab lwm qhov kawg yog txuas nrog qhov zoo electrode ntawm lub hwj chim mov, kom tag nrho cov nti yog encapsulated los ntawm epoxy resin. Lub semiconductor wafer yog tsim los ntawm ob qhov chaw, ib qho yog P-hom semiconductor, nyob rau hauv uas lub qhov yog, thiab lwm yam yog N-hom semiconductor, uas yog feem ntau electrons. Tab sis thaum ob lub semiconductors txuas nrog, P-N kev sib tshuam yog tsim los ntawm lawv. Thaum ib tug tam sim no siv rau lub nti los ntawm ib tug hlau, cov electrons raug thawb mus rau thaj tsam P, qhov twg cov electrons thiab qhov recombine, thiab ces lub zog yog emissions nyob rau hauv daim ntawv ntawm photons. Qhov no yog lub hauv paus ntsiab lus ntawm LED teeb emission. Lub wavelength ntawm lub teeb, uas yog xim ntawm lub teeb, yog txiav txim los ntawm cov khoom uas ua rau P-N junction.

LIBIPX7 / IPX8 Dej Immersion Chamber muab qhov tseeb thiab txhim khu kev qha kev ntsuas dej tsis zoo rau cov teeb ci LED, tso cai rau cov tuam txhab tsim khoom siv cov khoom lag luam hauv kev simulated sib sib zog nqus- dej thaum ua kom muaj kev nyab xeeb, rov ua dua, thiab cov qauv- kev sim ua raws.

Nws yog vim cov qauv no uas LED teeb muaj kev poob siab zoo thiab siab lumen. Lawv tau hloov cov roj teeb fluorescent ib txwm muaj nyob hauv ntau qhov chaw ua qhov chaw teeb pom kev zoo. Dab tsi yog cov qauv kev sim rau LED?

1. EN 55015: 2013
