Kev xaiv lub raj zoo LED yuav tsum muaj kev xav zoo los ntawm ntau yam, nrog rau kev ua haujlwm ntawm lub teeb, xim rendering, tshav kub dissipation, hom, ntawv pov thawj, thiab lwm yam. Cov hauv qab no yog cov lus qhia ntxaws ntxaws:
1. Saib ntawm lub teeb pom kev zoo (lm/W)- txuag hluav taws xob
Qhov siab dua lub teeb efficiency, lub zog txuag ntau dua. Feem ntau, qhov ua tau zoo ntawm lub teeb pom kev zoo ntawm - zoo LED raj yog siab dua 100lm / W, thiab siab - cov khoom kawg tuaj yeem ncav cuag 140-160lm / W.
Kev suav cov mis: Lub teeb efficiency (lm/W)=Luminous flux (lm) ÷ Fais fab (W)
Piv txwv li: 20W LED raj, luminous flux 2800lm, lub teeb efficiency=2800/20=140lm/W (tsim nyog)
Tsawg- cov khoom kawg tsuas muaj 70-80lm/W, siv hluav taws xob thiab qhov ci qis.
2. Saib cov xim rendering Performance index (CRI, Ra) - xim authenticity
Xim rendering Performance index (Ra) Ntau dua lossis sib npaug rau 80 (cov khw muag khoom pom zoo siab dua lossis sib npaug rau 85, cov zaub mov tshiab Loj dua lossis sib npaug rau 95),qhov siab dua cov xim, qhov tseeb nws yog.
Tsawg-kawg LEDs tsuas muaj Ra<70, and the color will be distorted when irradiating food and clothing.
3. Saib xim kub (K) - seb lub teeb sov los yog txias
3000K (sov daj lub teeb, haum rau tsev thiab tsev noj mov)
4000K (lub teeb ntuj tsim, haum rau chaw ua haujlwm thiab thaj chaw ntawm cov khw muag khoom loj)
5000K-6500K (lub teeb txias dawb, haum rau cov khoom noj tshiab thiab warehouses)
Kev pom zoo: Xaiv 4000K-5000K rau thaj chaw tseem ceeb ntawm cov khw muag khoom noj khoom haus thiab 5000K-6500K rau thaj chaw zaub mov tshiab.
4. Saib lub hom thiab nti
High -cov khoom lag luam zoo: Philips, Osram, Panasonic, NVC, Sanxiong Aurora, Sunshine Teeb pom kev zoo, thiab lwm yam.
Chip hom:
High-kawg: Cree, Osram, Lumileds
Nruab nrab - range: Epistar, Sanan
Tsawg- kawg: tsis paub hom chips (lub neej luv luv, lub teeb nrawm nrawm)
5. Saib cov qauv tsim hluav taws xob cua sov - cuam tshuam rau lub neej
Aluminium tshav kub dissipation plhaubyog zoo dua li yas plhaub (tsis zoo cua sov dissipation, ceev lub teeb lwj).
Lub teeb hlaws dai yog npaj sib npaug kom tsis txhob muaj cua sov hauv zos.
Qhov ci ntsa iab ntawm cov LEDs tsis zoo yuav poob qis tom qab 1-2 xyoos (lub teeb tawg hnyav).
6. Saib ntawm LED fais fab mov
Tsis tu ncua tam sim no LED fais fab movyog ruaj khov thiab muaj lub neej ntev dua RC tsav.
Hom fais fab mov: xws li Inventronics, Mean Well, thiab lwm yam.
Lub zog tsis zoo yog qhov yooj yim ua rau flicker thiab hlawv cov hlaws dai.
7. Saib daim ntawv pov thawj thiab kev ruaj ntseg zoo
Daim ntawv pov thawj kev nyab xeeb:CE, RoHS(EU environmental certification), UL (US certification), CCC (Tuam Tshoj Compulsory Certification).
Lub sijhawm lav: siab- cov khoom lag luam zoo feem ntau muab 3-5 xyoo lav, thaum cov npe qis dua tuaj yeem muab 1 xyoo xwb.
8. Lwm yam kev ceev faj
✅ Strobe test: siv lub koob yees duab xov tooj ntawm tes taw rau ntawm lub raj LED. Yog tias muaj kab txaij flashing, nws txhais tau hais tias tus neeg tsav tsheb tsis zoo.
✅ Tsis muaj teeb meem xiav xiav: xaivRG0 (tsis muaj kev phom sij), tshwj xeebhauv thaj chaw me nyuam yaus.
✅ Hloov T8 fluorescent teeb: xyuam xim rau kev sib raug zoo (ib zaug- xaus / ob npaug - xaus fais fab mov, seb lub tshuab hluav taws xob puas yuav tsum tau muab tshem tawm).
Cov ntsiab lus tseem ceeb rau kev yuav khoom siab - zoo LED teeb
Cov khoom siab- cov qauv zoo Tsawg- ua haujlwm kawg
Luminous efficiency Ntau dua los yog sib npaug rau 100lm / W<80lm/W
Xim rendering Performance index Ra Ntau dua los yog sib npaug rau 85 Ra<70
Xim kub 4000K-6500K (raws li xav tau) Cov xim sib txawv hnyav
Chip Cree / Osram / Lumileds Lwm hom chips
Thaum tshav kub kub dissipation Aluminium plhaub + tsim nyog qauv yas plhaub
Tsav qhov tsav tam sim no (hom fais fab mov) Resistor-capacitor tsav
Daim ntawv pov thawj CE / RoHS / CCC / UL Tsis muaj ntawv pov thawj
Warranty 3-5 xyoos 1 xyoos lossis tsis muaj
Kev yuav channel: Cov khw muag khoom lag luam tseem ceeb,cov kws tshaj lij teeb pom kev lag luam, zam cov- nqe thiab qis- cov khoom zoo.
Cov teeb ci LED xaiv nyob rau hauv txoj kev no tsis yog tsuas yog siab ci thiab ntev hauv lub neej, tab sis kuj txuag hluav taws xob thiab nyiaj txiag tiag tiag!
