DOB yog dab tsi?

MANUFACTURING PRINCIPLE OF DOB LAMP BOARD:

Nws combines ib tug optical engine nrog ib tug integrated on-board tsav tsheb. DOB yog lub npe luv rau "tus tsav tsheb". Hauv tsoosLED teeb pom kev zoosystems, tsav tsheb feem ntau yog cais los ntawm LED Cheebtsam thiab tsim nyob rau hauv lub FR4 luam Circuit Court board (PCB). Qhov kev teeb tsa no yog ua raws li kev xav tias LED tsav tsheb yog tsim los ntawm kev hloov hom fais fab mov. Cov neeg tsav tsheb SMPS feem ntau siv cov khoom loj, kim thiab tsis muaj kev ntseeg siab, xws li inductors thiab capacitors. Kev siv cov khoom siv reactive yuav tsum muaj FR4 pawg thawj coj saib, uas tuaj yeem muab cov khaubncaws sab nraud povtseg txaus rau cov khoom sib txuas. Nyob rau hauv ib qho kev sib xyaw teeb pom kev zoo, qhov ntim loj ntawm tus neeg tsav tsheb SMPS yuav tsum muaj qhov chaw txaus hauv lub teeb pom kev zoo kom haum rau cov tsav tsheb. Tsis tas li ntawd, reactance Cheebtsam xws li electrolytic capacitors yog rhiab heev rau qhov kub thiab txias. Kev teeb tsa chaw taws teeb tuaj yeem txo cov thermal stress Cheebtsam los ntawm LEDs.

DOB technology yog dab tsi?

Kev cob qhia LED teeb pom kev zoo - tshwj xeeb tshaj yog cov uas tuaj yeem tswj lub teeb - ua kom lub teeb pom kev zoo thaum txo kev siv hluav taws xob. Yog li ntawd, txhawm rau tswj cov teeb pom kev zoo thiab kev ntseeg siab ntawm lub teeb, peb siv cov khoom siv fais fab raws li tus tsav tsheb (DOB) thev naus laus zis.

DOB teeb pom kev zoo tsav hom yog ib hom tshiab LED tsav tsheb raws li ib txwm hloov pauv fais fab mov hom, uas ncaj qha hloov AC lub zog hluav taws xob mus rau DC, thiab tom qab ntawd tswj cov LED tam sim no los ntawm IC, kom cov LED tuaj yeem tso tawm tam sim no tsis tu ncua nyob rau hauv qee yam. ntau yam tsav tsheb LED teeb hlaws kom emit teeb.

MATERIAL DESCRIPTION NTAWM DOB LED Txoj Kev Teeb(LineAR LED Txoj Kev Teeb):

1. Lub teeb lub cev yog ua los ntawm txhuas tuag-casting, nrog ib tug filigree + kauv cua sov dissipation tsim, uas yuav ua tau zoo dissipate tshav kub thiab xyuas kom meej lub neej kev pab cuam ntawm lub teeb;

2. Qhov saum npoo ntawm lub teeb lub cev yog kho nrog cov hmoov sab nraum zoov, thiab cov tsos zoo nkauj thiab dav;

3. Nrog nanometer reflector, lub reflection efficiency ncav cuag ntau tshaj 90%;

4. High zog tempered iav yog saws, muaj zog compression kuj, siab transmittance thiab teeb pom kev zoo;

5. 360 degree adjustable lub kaum sab xis mounting bracket, yooj yim rau siv thiab ruaj;

6. Cov ntaub thaiv npog yog ua los ntawm cov hlau tsis muaj steel kom ntseeg tau tias siv sab nraum zoov thiab kav ntev;

DOB LED Txoj Kev Teeb (LINEAR LED Txoj Kev Teeb) APPLICATION SITE:

Chaw ntau pob square teeb pom kev zoo, hla lub teeb pom kev zoo, teeb pom kev hauv tsev, vaj toj roob hauv pes, qhov teeb pom kev zoo, teeb pom kev sab nraum zoov, thiab lwm yam;

Qhov zoo ntawm DOB projection teeb (linear projection teeb):

1) Nws tuaj yeem ua rau cov khoom siv ultralight thiab ultrathin, uas zoo nkauj thiab txuag nqi tsheb thauj mus los;

2) Nws yog qhov yooj yim rau kev tsim khoom thiab tuaj yeem ua tiav kom txuag tau tus nqi zog;

3) Tsawg qhov tsis xws luag ntawm cov khoom siv kho tshuab tag nrho;

4) Raws li cov IC nti thiab LED nyob rau tib lub txhuas substrate, lub nti muaj qhov kub thiab txias tiv thaiv taw tes, uas yuav tiv thaiv thaum qhov kub thiab txias siab dhau, ua haujlwm zoo rau kev pab cuam lub neej ntawm LED;

5) Tsis muaj electrolytic capacitor, kev ua haujlwm ruaj khov, tus nqi qis thiab lub neej ua haujlwm ntev;

6) Nrog lub zog loj, nws tuaj yeem txuag hluav taws xob thiab hluav taws xob hauv kev txiav txim siab tiag tiag hauv kev siv tswv yim;

7) Nws pib tam sim ntawd thaum lub teeb qhib, tsis tas yuav tos, thiab sai dua li ib txwm LED.

Qhov zoo ntawm kev siv DOB tsav tsheb?

Ultra nyias thiab lub teeb, txuag nqi tsheb thauj mus los.

Tsis siv neeg puv SMT txuag nqi zog thiab txo tus nqi ntawm cov khoom puas.

Kev tiv thaiv kub dhau, IC nti thiab LED nyob rau tib lub PCB, txuas ntxiv lub neej ntawm LED.

Yuav luag tsis muaj electrolytic capacitor caij, ruaj khov thiab tus nqi qis dua.

Tam sim no, sai dua li cov teeb pom kev zoo.
