Benwei Teeb pom kev zoo: Yuav ua li cas txiav txim qhov zoo thiab qhov tsis zoo ntawm LED kev lag luam thiab mining teeb qhov chaw?
Raws li lub teb chaws muaj kev lag luam loj, teeb pom kev siv hluav taws xob siv nyiaj rau qee qhov kev siv hluav taws xob hauv cov chaw tsim khoom. Yog li ntawd, kev siv ib yam tshiab ntawm LED teeb qhov chaw raws li lub teeb-emitting khoom-LED high bay lub teeb, uas yuav ua tau cov nyhuv ntawm lub zog txuag thiab kev tiv thaiv ib puag ncig, tau ua lub hom phiaj ntawm tib neeg' . Yog li dab tsi cuam tshuam rau qhov zoo ntawm LED kev lag luam thiab mining teeb pom kev zoo, thiab yuav ua li cas txiav txim qhov zoo thiab qhov tsis zoo ntawm LED kev lag luam thiab mining lub teeb? Hauv qab no, kuv yuav txheeb xyuas cov hauv qab no:
Yuav txiav txim qhov zoo thiab qhov tsis zoo ntawm LED kev lag luam thiab mining teeb qhov chaw:
1. Xav txog cov yam ntxwv hluav taws xob ntawm semiconductor lub teeb-emitting diodes los ntawm kev ua haujlwm hluav taws xob ntawm LED kev lag luam thiab mining lub teeb
Cov yam ntxwv hluav taws xob ntawm PN kev sib tshuam ntawm LEDs yog unidirectional nonlinear conductivity, low-voltage drive, thiab rhiab heev rau hluav taws xob zoo li qub. Sib txawv ntawm cov yam ntxwv hluav taws xob ntawm cov teeb pom kev zoo ib txwm muaj, qhov ntsuas qhov tseem ceeb suav nrog rau pem hauv ntej tsav tam sim no, rau pem hauv ntej voltage poob, thim rov qab tam sim no, rov qab tawg voltage, thiab electrostatic rhiab heev.
2. Xav txog qhov ua tau zoo ntawm cov cua kub dissipation ntawm PN hlws ris kub ntawm lub hwj chim LED
Nws yog ib qho tseem ceeb tshwj xeeb uas yuav ua rau LED siab bay teeb kom tau txais lub zog siab dua thiab kev ua haujlwm luminous, thiab daws cov teeb meem ntawm PN hlws ris kub thiab plhaub kub dissipation ntawm lub zog LEDs rau teeb pom kev zoo. Lub thermal kev ua tau zoo ntawm LED siab bay teeb feem ntau yog txiav txim los ntawm cov tsis xws li thermal resistance, case temperature, thiab junction temperature.
3. Kev ntseeg siab ntawm LED ua haujlwm thiab lub neej ntev
Tshwj xeeb, LED kev lag luam thiab cov teeb pom kev tsuas yog qhov tseem ceeb dua li ob qhov ntsuas ntawm LCD backlight thiab cov ntxaij vab tshaus loj. Qhov ntev ntawm lub neej ntawm LED peb ntsuas tsis yog hais txog lub sijhawm siv tau los ntawm kev siv kom puas, tab sis hais txog lub sijhawm ntawm LED nyob rau hauv cov nqi zog, thaum lub luminous flux decays mus rau qhov feem pua ntawm cov nqi pib. Lub sijhawm ntev dua, lub neej ntev ntawm LED.
4. Xav txog kev nyab xeeb ntawm hluav taws xob ntawm LED teeb qhov chaw rau kev lom neeg lossis tib neeg lub cev
Txij li thaum lub teeb ci ntawm LED siab bay lub teeb yog lub teeb nqaim, lub teeb ci siab lub teeb pom kev zoo, nws cov hluav taws xob yuav ua rau muaj teeb meem rau lub retina ntawm tib neeg lub qhov muag, yog li International Electrotechnical Commission IEC siv rau LED high bay teeb qhov chaw. rau lub sijhawm sib txawv. Cov kev txwv hluav taws xob muaj txiaj ntsig zoo thiab cov qauv kev sim tau teev tseg, uas tseem yog qhov tseem ceeb rau kev txiav txim siab qhov zoo ntawm LED high bay teeb. Ntawm lawv, European Union thiab Tebchaws Meskas ua qhov yuav tsum tau ua rau kev kuaj xyuas hluav taws xob LED.
