Yuav ua li cas LED Ceiling Lub teeb ua kom sov Dissipation

Teeb hlaws
Feem ntau, rau lub zog loj dua 30W, 1W LED hlaws feem ntau yog siv, thaum lub zog tsawg dua 30W, qis zog LED hlaws (xws li 302030143528, thiab lwm yam) feem ntau yog siv. Nws raug nquahu kom siv thaj chaw uas tsis muaj zog LEDs rau cov cua sov dissipation thiab txhawm rau txhim kho qhov sib xws ntawm lub teeb emission. Teeb hlaws tuaj yeem npaj raws li lawv cov duab. Piv txwv li, yog hais tias cov duab yog ncig, cov hlaws dai yuav muab teem rau hauv ib ncig. Hloov pauv, yog tias cov duab yog square, cov hlaws yuav raug teeb tsa hauv cov duab square.
Muaj ob lub voj voog ntawm LED hlaws rau ntawm lub voj voog luam tawm, uas siv 23 0.4W 5730 hom LED hlaws nrog tag nrho lub zog ntawm 18W. Cov duab plaub nyob rau hauv nruab nrab yog nws cov khoom siv hluav taws xob tas li tam sim no, thiab lub kaum sab xis ntawm lub thawv square yog photodiode ntawm cov chaw taws teeb tswj receiver, uas tau txais cov teeb liab infrared tswj ntawm cov chaw taws teeb tswj brightness.
Nws yuav tsum tau muab sau tseg tias tseem muaj ntau tus nqi qis LED qab nthab teeb uas siv lub teeb qis qis straw kaus mom teeb. Txawm li cas los xij, vim muaj kev kub ntxhov siab ntawm straw kaus mom teeb (450 degree / W), nws nyuaj rau dissipate tshav kub, ua rau lub teeb tawg loj thiab luv lifespan.
Lampshade
Lub teeb lub teeb feem ntau yog ua los ntawm PC board, thiab nws cov kev ua tau zoo yog raws li hauv qab no:
(1) Transmittance: Qhov siab tshaj plaws kev xa tawm ntawm PC board tuaj yeem ncav cuag 89%, uas yog piv rau iav. UV coated boards yuav tsis ua yellowing, fogging, los yog tsis zoo lub teeb kis tau tus mob thaum raug tshav ntuj. Tom qab kaum xyoo, qhov poob ntawm lub teeb xa mus tsuas yog 6%, thaum qhov poob ntawm PVC yog siab li 15% -20%, thiab cov iav fiber ntau yog 12% -20%.
(2) Impact resistance: Qhov cuam tshuam lub zog ntawm PC board yog 250-300 npaug ntawm cov iav zoo tib yam, 30 npaug ntawm acrylic board nrog tib tuab tuab, thiab 2-20 zaus ntawm tempered iav. Nws tuaj yeem poob qis dua ob metres nrog 3kg rauj yam tsis muaj qhov tawg thiab hu ua "unbreakable iav" thiab "suab hlau".
(3) Kev tiv thaiv UV: Ib sab ntawm PC board yog coated nrog UV resistant txheej, thiab lwm sab yog kho nrog anti condensation, combining UV tsis kam, rwb thaiv tsev kub, thiab anti drip functions. Nws tuaj yeem thaiv UV rays los ntawm kev hla thiab tsim nyog rau kev tiv thaiv cov khoom muaj txiaj ntsig thiab cov khoom pov thawj los ntawm UV puas.
(4) Lub teeb yuag: Nrog rau lub ntiajteb txawj nqus tsuas yog ib nrab ntawm cov iav, nws txuag ntawm kev thauj mus los, tshem tawm, teeb tsa, thiab txhawb nqa tus nqi.
(5) Nplaim hluav taws xob: Raws li lub teb chaws tus qauv GB50222-95, PC boards raug cais raws li Class B1 nplaim taws retardant. Lub ignition point ntawm lub PC board nws tus kheej yog 580 degrees Celsius, thiab nws yuav tua tus kheej tom qab tawm hauv hluav taws. Thaum hlawv, nws yuav tsis tsim cov pa phem thiab yuav tsis txhawb kev sib kis ntawm hluav taws.
(6) Flexibility: Raws li cov qauv tsim, kev khoov txias tuaj yeem siv rau ntawm qhov chaw tsim kho los nruab rau hauv koov, lub ru tsev semi-circular, thiab cov duab qhov rais. Qhov tsawg kawg nkaus dabtsi yog khoov vojvoog yog 175 npaug ntawm lub thickness ntawm lub rooj tsavxwm, thiab nws kuj yuav kub khoov.
(7) Kev hloov pauv kub: Lub rooj tsav xwm PC tsis dhau qhov txias txias ntawm -100 degree, tsis soften ntawm 135 degree, thiab nws cov khoom siv kho tshuab tsis qhia cov kev hloov pauv tseem ceeb hauv ib puag ncig hnyav.
(8) Huab cua tsis kam: PC boards tuaj yeem tswj tau qhov kev ruaj ntseg ntawm ntau yam ntsuas lub cev nyob rau hauv thaj tsam ntawm -40 degree txog 120 degree . Tom qab 4000 teev ntawm kev kuaj kev nyab xeeb kev laus, qhov yellowing degree yog 2 thiab qhov txo qis hauv kev xa tawm tsuas yog 0.6%.
