5 cov lus qhia tshwj xeeb rau LED vaj huam sib luag teeb
Peb feem ntau tau txais kev nug los ntawm cov neeg siv khoom rau LED vaj huam sib luag teeb, tab sis vim peb tsis paub txog cov lus qhia tshwj xeeb thiab cov ntsiab lus ntawm LED vaj huam sib luag teeb, peb feem ntau yuav tsum tau piav qhia rau cov neeg siv khoom ntev ua ntej lawv tuaj yeem nkag siab. Hauv kev teb rau qhov tshwm sim no, cov hauv qab no yog ib qho kev piav qhia thiab kev sib koom ntawm 5 feem ntau siv cov lus qhia thiab cov ntsiab lus ntawm LED vaj huam sib luag teeb, uas kuj yog rau kev siv ntawm kev yuav cov phooj ywg:
LED loj:
1. 0603, 0805, 1210, 5050 xa mus rau lub teeb -emitting element siv nyob rau hauv LED vaj huam sib luag teeb---- qhov loj ntawm LED (imperial / metric), cov hauv qab no yog cov ncauj lus kom ntxaws qhia txog cov no specifications:
ib. 0603: Hloov mus rau metric, nws yog 1005, uas txhais tau hais tias qhov ntev ntawm LED lub ntsiab yog 1.0 hli thiab qhov dav yog 0.5 hli. Kev lag luam luv luv yog 1005, thiab lub npe imperial yog 0603.
b. 0805: Hloov mus rau metric system, nws yog 2125, uas txhais tau hais tias qhov ntev ntawm lub teeb LED yog 2.0mm thiab qhov dav yog 1.25mm. Kev lag luam luv luv yog 2125, thiab lub npe imperial yog 0805.
c. 1210: Hloov mus rau metric, nws yog 3528, uas txhais tau hais tias qhov ntev ntawm cov khoom siv LED yog 3.5 hli thiab qhov dav yog 2.8 hli. Kev lag luam luv luv yog 3528, thiab lub npe imperial yog 1210.
d. 5050: Qhov no yog lub npe metric, uas txhais tau hais tias qhov ntev ntawm cov khoom siv LED yog 5.0mm thiab qhov dav yog 5.0mm. Kev lag luam raug xa mus rau 5050.
Number of LED teeb:
15 teeb, 30 teeb, thiab 60 teeb xa mus rau ntau npaum li cas LED Cheebtsam yog welded ib meter ntev ntawm LED vaj huam sib luag teeb. Feem ntau hais lus, 1210 specification lub teeb sawb yog 60 LEDs ib 'meter', thiab 5050 specification lub teeb sawb yog 30 LEDs ib 'meter'. ntawm 60 LEDs ib meter. Tus nqi ntawm LED vaj huam sib luag teeb nrog cov lej sib txawv ntawm LEDs yog qhov sib txawv, uas kuj yog ib qho tseem ceeb kom paub qhov txawv ntawm tus nqi ntawm LED vaj huam sib luag teeb.
Xim kub:
1. Xim kub yog hais txog cua sov lub cev dub. Thaum kub nce mus rau ib theem, cov xim pib hloov ntawm tsaus liab - lub teeb liab - txiv kab ntxwv daj - dawb - xiav, thiab maj mam hloov. Qhov kub thiab txias yog hu ua xim kub ntawm lub teeb ci. Feem ntau hais lus, xim kub tsis yog qhov taw qhia rau kev ntsuam xyuas LED vaj huam sib luag teeb, tab sis ntau tus neeg siv khoom txawv teb chaws yuav thov tshwj xeeb vim qhov chaw siv.
2. Cov xim kub ntawm lub teeb ci txawv, thiab xim ntawm lub teeb kuj txawv:
ib. Cov xim kub yog qis dua 3300K, thiab lub teeb xim yog reddish los muab qhov sov so; muaj qhov chaw ruaj khov thiab sov so. Feem ntau hu ua sov xim kub.
b. The color temperature is in the middle of 3000--6000K, people have no obvious visual psychological effect under this color tone, and have a refreshing feeling; so it is called "neutral" color temperature
c. Cov xim kub yog tshaj 6000K, thiab lub teeb xim yog xiav, ua rau tib neeg lub siab txias, feem ntau hu ua txias xim kub.
Brightness: cd (candela)
Lub hauv paus chav tsev ntawm luminous siv, candela yog ib qho ntawm cov theem pib ntawm International System of Units. Feem ntau, cov xim sib txawv ntawm LED vaj huam sib luag teeb yuav muaj qhov sib txawv luminous siv. Chav tsev yog mcd, uas yog, millicandela. Qhov siab dua tus nqi, qhov ntau dua qhov luminous siv, uas yog, qhov ci dua. Qhov no yog qhov taw qhia tseem ceeb rau kev ntsuas qhov ci ntawm LED vaj huam sib luag teeb. Qhov siab dua qhov yuav tsum tau muaj qhov ci ci, qhov kim dua lub teeb strips yog. Qhov no yog vim qhov siab -brightness LED chips kim, thiab qhov siab dua qhov ci, qhov nyuaj dua rau pob.
Beam angle:
Qhov no yog hais txog lub teeb -emitting kaum sab xis ntawm LED Cheebtsam ntawm LED vaj huam sib luag teeb. Feem ntau, qhov dav -lub hom phiaj SMD LED, uas yog, lub teeb -emitting lub kaum sab xis ntawm SMD Cheebtsam, yog 120 degrees. Lub teeb loj dua -emitting lub kaum sab xis, qhov zoo dua qhov astigmatism nyhuv, tab sis qhov ci ntawm lub teeb raug txo qis. Thaum lub teeb -emitting lub kaum sab xis me me, qhov kev siv ntawm lub teeb yuav nce, tab sis qhov ntau ntawm illumination yuav raug txo. Yog li ntawd, lwm qhov taw qhia tseem ceeb rau kev ntsuam xyuas LED vaj huam sib luag teeb yog lub luminous lub kaum ntse ntse. Muaj qee tus neeg tsim khoom phem nyob hauv khw. Txhawm rau kom qhov ci ci ntawm lub teeb kom tau txais txiaj ntsig ntau dua, lawv txhob txwm ua kom lub teeb pom kev zoo -emitting lub kaum sab xis. Yog tias koj tsis ceev faj, koj yuav yuav cov khoom tsis zoo li no.
Voltage:
Qhov no yog hais txog qhov input voltage ntawm LED vaj huam sib luag teeb. Feem ntau siv tshwj xeeb yog DC 12V, thiab qee qhov yog 24V.
