Lub ntsiab lus ntawm COB encapsulation
Lub COB yog hu ua Chips on Board (COB), uas yog ib qho cuab yeej siv los daws qhov teeb meem ntawm LED kub dissipation. Piv nrog rau hauv-kab thev naus laus zis thiab SMD, nws muaj ntau yam ntawm qhov chaw txuag, yooj yim ntim, thiab kev tswj xyuas thermal zoo heev.
Lub COB encapsulation, uas yog, nti On board, yog ua raws li cov nti liab qab mus rau kev sib tshuam substrate nrog conductive los yog tsis-conductive kua nplaum, thiab tom qab ntawd ua cov hlau sib txuas kom paub txog kev sib txuas hluav taws xob. Yog tias cov nti liab qab raug ncaj qha rau saum huab cua, nws raug cuam tshuam los ntawm kev sib kis los yog kev puas tsuaj rau tib neeg, cuam tshuam los yog rhuav tshem cov haujlwm ntawm cov nti, yog li cov nti thiab cov hlua khi yog encapsulated los ntawm cov kua nplaum. Cov pob no kuj tseem hu ua soft encapsulation.
Qhov zoo ntawm COB ntim
1. Ultra-nyias: Raws li qhov xav tau tiag tiag ntawm cov neeg siv khoom, PCB board nrog tuab ntawm 0.4-1.2mm tuaj yeem siv los txo qhov hnyav rau 1/3 ntawm cov khoom qub qub, uas tuaj yeem txo cov qauv, kev thauj mus los thiab engineering. cov nqi rau cov neeg siv khoom.
2. Anti-kev sib tsoo thiab compression: Cov khoom COB ncaj qha encapsulates LED nti nyob rau hauv lub concave teeb txoj hauj lwm ntawm lub PCB board, thiab ces yog kho los ntawm epoxy resin. Qhov saum npoo ntawm lub teeb taw tes yog convex rau hauv ib qho chaw kheej kheej, uas yog du thiab tawv, thiab tiv taus kev sib tsoo thiab hnav.
3. Loj saib lub kaum ntse ntse: COB pob siv ntiav zoo kheej kheej illumination, lub kaum sab xis saib yog ntau tshaj 175 degrees, ze rau 180 degrees, thiab muaj ib tug zoo optical diffuse xim dimming nyhuv.
4. Khoov tau: Khoov muaj peev xwm yog qhov tshwj xeeb ntawm COB sib dhos. PCB dabtsi yog khoov tsis ua kev puas tsuaj rau encapsulated LED chips. Yog li ntawd, LED arc cov ntxaij vab tshaus, cov ntxaij vab tshaus, thiab cov ntxaij vab tshaus tuaj yeem tsim tau yooj yim siv COB modules. Nws yog ib qho zoo tagnrho substrate rau tus kheej cov ntxaij vab tshaus nyob rau hauv tuav thiab nightclubs. Nws tuaj yeem ua seamlessly spliced, cov qauv tsim tau yooj yim, thiab tus nqi qis dua li LED zoo li lub vijtsam ua los ntawm lub rooj tsav xwm hloov tau yooj yim thiab cov khoom siv ib txwm siv.
5. Muaj zog cua sov dissipation: COB cov khoom tau ntim rau ntawm lub rooj tsavxwm PCB, thiab cov cua sov ntawm cov wick tau xa mus sai heev los ntawm cov ntawv ci tooj liab ntawm lub rooj tsavxwm PCB. Lub thickness ntawm cov ntawv ci tooj liab ntawm PCB lub rooj tsavxwm muaj cov kev cai nruj heev, thiab vim yog cov txheej txheem kub immersion, nws tsis tshua muaj teeb meem loj. Yog li ntawd, muaj tsawg heev LED kev puas tsuaj thiab cov khoom COB zoo heev rau lub neej.
6, hnav-tiv taus, yooj yim los ntxuav: qhov chaw ntawm lub teeb taw tes yog convex rau hauv ib qho chaw spherical, du thiab tawv, kev sib tsoo-resistant thiab hnav-resistant; Yog tias muaj qhov chaw tuag, koj tuaj yeem kho qhov taw tes ntawm taw tes; tsis muaj daim npog qhov ncauj, plua plav tuaj yeem ntxuav nrog dej lossis ntaub.
7, Cov yam ntxwv zoo tagnrho huab cua: nws triple tiv thaiv kev kho mob, tsis muaj dej, pov thawj noo noo, tiv thaiv corrosion, tiv thaiv plua plav, tiv thaiv zoo li qub, tiv thaiv oxidation, UV tiv thaiv zoo heev. Yog li nws muaj peev xwm ua tau raws li tag nrho cov huab cua ua haujlwm, qhov kub sib txawv ntawm rho tawm 30 degrees rau xoom 80 degrees tseem tuaj yeem siv tau ib txwm.
