Lub zog hluav taws xob loj ntawm cov teeb ci hluav taws xob muaj teeb meem tseem yog vim li cas ib qho ntawm LED ntim cov khoom lag luam, uas yog qhov tseem ceeb tshaj plaws hauv kev xa cov hluav taws xob semiconductor mus rau hauv cov hluav taws xob dav dav. Vim tias tam sim no cov kev txwv ntawm semiconductor lub teeb hluav taws xob diode nti thev naus laus zis, photoelectric hloov dua siab zog ntawm lamppost teeb moos LED xav tau kev txhim kho, tshwj xeeb tshaj yog LED yas teeb lub zog hluav taws xob LEDs. Vim tias lawv lub zog siab dua, kwv yees li 60% ntawm hluav taws xob lub zog yuav dhau los ua thermal lub zog tso tawm (Nrog txoj kev tsim khoom ntawm cov khoom siv hluav taws xob, qhov kev hloov pauv hluav taws xob yuav maj mam nce ntxiv), uas yuav tsum kom cov neeg siv thov cov hluav taws xob ntau ntawm cov teeb ci LED, ua ib qho txoj haujlwm zoo ntawm kev ua kom sov siab txhawm rau kom paub tseeb tias kev ua haujlwm zoo ntawm lub zog hluav taws xob teeb lub teeb roj LED cov khoom lag luam.
LED yas teeb taws teeb taws kub dab dej pom.
Cov tsos thiab cov ntaub ntawv raw: Yog tias qhov yuav tsum tau khi ntawm cov khoom tsis tau siab, kev sib txuam yuav tshwm sim ncaj qha nrog huab cua huab cua sab nraud. Nws raug nquahu kom siv cov finned aluminium lossis tooj liab fins.
Txog LED teeb moos 1W siab zog LED lub teeb dawb (lwm yam xim yog qhov zoo ib yam) cov dab dej tso cua sov feem ntau pab tau thiab tag nrho thaj tsam ntawm cov cua sov ua kom sov yog ≥50 square centimeters. Hais txog 3W cov khoom lag luam, nws raug pom zoo tias tag nrho cov txheej txheem zoo hauv thaj chaw ntawm lub dab dej kub yog ≥150 square centimeters. Lub zog siab dua tau ntxiv nyob ntawm qhov xwm txheej thiab qhov sim ua tau zoo. Sim ua kom ntseeg tau tias qhov ntsuas kub ntawm lub dab dej kub tsis dhau 60 ° C.
3. LED yas teeb lub teeb ci LED high-power txuas hom:
Thaum sib txuas ntawm LED yas teeb lub zog siab LED lub zog tso rau hauv lub dab dej, thov kom paub meej tias qhov chaw kov ntawm ob sab yog tiaj tus kom ua rau kev sib txuas ntawm ob lub ntsej muag kov kom ntau dua. Nws raug nquahu kom thov txheej txheej ntawm cov roj ua hluav taws xob nyob hauv qab ntawm LED teeb moos soos los yog nplaim hluav taws kub. Lub hau roj ua kom sov yuav tsum thov kom zoo thiab kom raug, thiab tom qab ntawd tsau nrog ntsia hlau.
