Led teeb pom kev zoo muaj lub zog loj-txuag, yuav hloov cov teeb pom kev zoo ib txwm, uas yuav ua rau lub kiv puag ncig plaub hauv keeb kwm ntawm tib neeg teeb pom kev zoo, zoo heev txhim kho lub chaw nyob ntawm tib neeg, txo qhov teeb meem loj zuj zus ntawm lub zog hauv ntiaj teb, ntawm tib lub sijhawm thaum LED teeb ci ntsa iab, coj tsav lub zog tsav hluav taws xob yog kev lav paub ntawm kev txhim kho ntawm LED kev lag luam saw. Qhov zoo ntawm LED fais fab mov ncaj qha txwv txoj kev ntseeg tau ntawm cov khoom lag luam LED.
Vim tias LED yog qhov cuab yeej hluav taws xob tsis zoo, thiab muaj cov yam ntxwv tsis zoo rau qhov kub thiab txias, yog li nyob rau hauv daim ntawv thov cov txheej txheem ntawm nws qhov kev xav tau kev ruaj khov ua haujlwm lub xeev thiab kev tiv thaiv, ua rau lub tswv yim ntawm kev tsav tsheb. Led cov khoom siv yuav luag zoo li qhov xav tau tsav lub zog, tsis zoo li cov qij qij uas tsis siv neeg, uas tuaj yeem txuas ncaj qha mus rau 220V AC hluav taws xob. Led yog qhov tsawg-voltage 2 ~ 3 volts tsav, yuav tsum tsim lub hauv paus hloov hluav taws xob, kev siv hluav taws xob sib txawv ntawm LED teeb, kom muaj cov twj siv hluav taws xob sib txawv. Hauv kev ua lag luam thoob ntiaj teb, cov neeg siv khoom txawv teb chaws muaj qhov kev xav tau ntawm kev hloov pauv hloov pauv, muaj lub zog zoo, qhov tseeb tam sim no qhov tseeb, lub neej siv hluav taws xob thiab kev siv lub tshuab hluav taws xob ntawm lub zog tsav tsheb tsav LED, vim tias lub zog tseem ceeb npaum li tib neeg lub siab hauv teeb pom kev zoo.
