General Teeb Pom Kev Zoo

Sij hawm: 2020-04-09

Kab lus no yog sau rau cov neeg koom nrog hauv qhov chaw teeb pom kev zoo, suav nrog cov qauv siv teeb pom kev zoo, kws kes duab vajtse, engineers thiab cov khoom tsim teeb pom kev zoo.


Nov yog qee lo lus teeb pom kev dav dav uas cov neeg feem coob hauv kev lag luam, chaw lag luam thiab uyility yuav tsum paub.


COB (tej daim ntawm board)


COB (chips on board) yog LED ntim thev naus laus zis siv rau LED teeb pom kev ua lag luam.


Ntau cov chips LED yog ntim ua ke ntawm LED substrate cov laug cam. Muaj cov cooper boards, aluminium boards, ceramic ceramic thiab li ntawd. Ntawm cov kev xaiv no, cov nti rau ntawm lub rooj tsavxwm ceramic LED muaj kev ua tau zoo dua hauv kev hais txog kev ua haujlwm ntawm lub teeb pom kev zoo thiab lub teeb ci txo.


Qhov loj ntawm pawg thawj coj tuaj yeem yog txij li mini meters txog ob peb centimeters, uas nyob ntawm lub peev xwm ntawm kev nthuav dav hauv tuam txhab.

SMD


Tshuab deg-mount LEDs yog qhov kev txhawj xeeb tshaj plaws ntawm LED nyob hauv kev ua lag luam. Feem ntau ntsia rau hauv cov sib txawv PCB ntse kom haum rau cov teeb lossis cov khoom sib txawv.

Cov qauv SMD yooj yim yog 2828, 3535, thiab 5050. Piv txwv, 2828 qhia tias qhov dav ntawm SMD yog 2.8 hli thiab qhov siab yog 2.8 hli.


Xim Qhia Txog Qhov Ntsuas


Qee lub teeb cov wil qhia kev dag. Qhov xim ntawm cov khoom hauv qhov tawm ntawm sab nraud yog txawv ntawm sab hauv tsev. Tias vim tias lub teeb muaj qhov sib txawv hauv cov xim muaj peev xwm.


Kev Ntsuas Cov Duab Uas Txaus Ntsuas, kuj tseem hu ua CRI, yog qhov ntsuas ntawm lub peev xwm ntawm kev rov ua xim. CRI tsuas yog suav qhov siab tshaj plaws rau 100, thiab qhov siab dua qhov ntsuas, qhov ua kom zoo dua xim.


Rau cov phiaj xwm teeb pom kev zoo sab nraum zoov, sab nraum zoov CRI ntau yog RA70 txog RA80, thaum CRI sab hauv tsev yog RA85 rau RA90.Tab sis rau qhov chaw tshwj xeeb, xws li chav ua yeeb yam, chav ua haujlwm luam ntawv, lossis lwm qhov chaw uas xav tau kev hloov xim siab, CRI Performance index tuaj yeem ncav cuag RA95 rau RA98 lossis siab dua.

Xim kub


Xim kub yog qhov ntsuas qhov sov sov los yog txias lub teeb ci los ntawm lub teeb yog. Txoj hauv kev ntsuas kev ntsuas yog dhau los ntawm Kelvin Qhov ntsuas kub.


Cov xim sov li pom kev sib daj nrog daj thiab feem ntau hnov ​​mos mos thiab xis. Thiab cov xim txias tau tinged nrog xiav thiab tshwm dawb dua, ua rau lawv ntau dua 'ncaj ncees' thiab tsis zam lub teeb, uas zoo dua rau kev ua haujlwm ib puag ncig dua so.


Teeb Pom Kev Zoo


Lub Teeb Pom Kev Zoo yog qhov ntsuas siv los ntsuas qhov sib piv ntawm lub teeb tawm rau lub zog siv. Chav tsev yog lumens ib watt. Kev siv hluav taws xob ntau dua txhais tau tias txuag ntau lub zog thiab yog lub zog txuag hluav taws xob.


The lighting efficiency of normal light sources can reach 140lm/w to 160lm/w, while the lighting efficiency of some outstanding models can exceed 180lm/w, which is far away from other lighting equipment.


Txawm li cas los xij, thaum lub teeb pom kev raug teeb tsa ntawm lub teeb coj, lub teeb pom kev zoo yuav tsawg dua vim tias thaum lub teeb pom kev dhau los ntawm lub teeb, lub teeb pom kev zoo yuav raug noj thiab nqus los ntawm lub cev hlau.Qhov no yog vim li cas cov teeb txoj kev ib txwm siv LED teeb pom kev zoo Cov.

Lumen


Lumen, the unit of light flow. The lumen rating of a lamp is a measure of the total light output of the lamp. It is used to describe the ability of the light source radiation to produce a strong or weak visual response per unit time. The unit is lumen, also called brightness.


Kwv yees lumens ntawm cov teeb (lumens / watt):


* Incandescent teeb, 15

* Dawb LED, 80-200

* Lub teeb fluorescent, 50

* Tshav ntuj ci, 94

* Cov roj ntsha tsis huv, 120

* Zog txuag hluav taws teeb, 60-80

* LED, 80-130


* Thov nco ntsoov tias cov lumens kwv yees thiab tej zaum yuav txawv vim yog cov tuam txhab tsim khoom sib txawv.




Lux


Lux yog chav ntsuas ntawm teeb pom kev zoo, uas qhia tau hais tias ntau npaum li cas ntawm lub teeb muaj teeb meem saum npoo. Ib qho lux yog txhais tau tias lub teeb pom kev tsim tawm thaum muaj ib lumen qhov xwm txheej ntawm ib qhov xwm fab xwm meem, yog li ib qho Lux yog ib qho Lumen ib cheeb tsam square xwm.


Lub teeb ci ntsa iab ntawm hnub ci yog 100,000 lux. Cov ncaws pob tso tawm xov tooj cua hauv TV yuav tsum muaj qhov pom kev zoo ntawm 16,000 lux. Lub chav ua noj xav tau txog 500 lux. Pej xeem kev thaum tsaus ntuj yuav tsum muaj txog 30 lux.




Kev pom kev


The degree of illumination required by the surface depends mainly on the type or nature of the cov hauj lwm lossis tib neeg kev ua ub no ntawm lub ntsej muag ci ntsa iab.


Yog li ntawd, kauj ruam 1 yog txhawm rau txiav txim siab ntau npaum li cas ntxiv xav tau. Hom haujlwm, lub sijhawm siv, hnub nyoog thiab pes tsawg tus neeg ua haujlwm hauv thaj chaw, kev ua haujlwm siab, thiab muaj lub teeb ua haujlwm yog txhua yam uas txiav txim siab txog qhov tsis pom kev.


Kauj Ruam 2 yog txiav txim siab tus naj npawb thiab hom ntawm cov khoom siv hluav taws xob xav tau los tsim ua lub teeb ci zoo li cas. Peb lub ntsiab tseem ceeb yuav tsum raug txiav txim siab.


* Cov hom ntawm cov Light source: cost, color and life of the light source are the main determinants of the light source type.


* Qhov teeb meem hluav taws xob muaj teeb meem li kev cai lij choj. Lub teeb pom kev zoo nyob rau saum npoo yog sib npaug rau cov square ntawm qhov kev ncua deb, uas ua rau qhov kev ncua deb ntawm lub teeb ci yog qhov tseem ceeb.


*Qhov sib koom ua ke ntawm kev siv tseem yog qhov tseem ceeb uas txiav txim siab ntau npaum li cas ntawm lub luminous flux tau dhau los ntawm lub teeb ci ntawm qhov xav tau ntawm nto. Reflectors, teeb lub teeb thiab lub teeb ci tuaj yeem ntxiv lossis txo qis siv. Kev siv ntawm cov roj teeb kev lag luam zoo tuaj yeem ncav cuag 90%.



LED Array lossis Module


In the assembly of LED package (components) or dies on a printed circuit or substrate, the optical element may have additional thermal, mechanical, and used to connect an electrical load to the LED drive interface side. The device has no power supply and standard lamps. The device cannot be directly connected to the branch circuit.


It may carry optical components and other thermal, mechanical, and electrical interfaces that are intended to connect to the load side of the LED driver.
