Kev piav qhia
Chip on Board, uas yog COB sawv cev rau, txhais tau tias "chip on board" lossis "integrated surface light source" hauv Suav. Nws yog kev txiav ntug LED ntim txheej txheem.
Tsoos LED hlaws dai (xws li SMD):Txhua tus neeg LED nti yog cais cais rau hauv ib lub hlaws me me, thiab tom qab ntawd cov hlaws me me no tau muab qhwv rau hauv lub rooj tsavxwm.
COB Technology:Nws suav nrog kev sib koom ua ke ncaj qha thiab ntim ntau lub chips LED ntawm tib lub substrate los tsim lub teeb ntom ntom thiab ua tiav lub teeb -emitting nto.

Daim ntawv thov
Cov nram qab no ua rau COB downlights sawv tawm:
High light output thiab brightness:theem ntawm kev sib koom ua ke ntawm cov chips yog siab, thiab muaj ntau lub teeb nyob rau hauv ib cheeb tsam. Vim li no, COB downlights feem ntau ci heev thiab muaj lub teeb pom kev zoo.
Uniform thiab zoo meej lub teeb pom kev:Ib qho zoo tshaj plaws ntawm COB downlights yog tias lawv muab tawm txawm, lub teeb zoo meej. Lub teeb nws muab tawm yog mos heev thiab txawm tias nws los ntawm qhov chaw. Nws ua kom zoo nkauj heev, ib txwm hloov lub teeb me ntsis yam tsis muaj duab ntxoov ntxoo thaum nws ci rau ntawm phab ntsa lossis khoom, uas yog qhov pom kev zoo. Qhov no tseem ceeb heev rau cov xwm txheej uas xav tau tsom teeb pom kev zoo thiab tsim kom muaj lub siab xav.
High xim rendering:Lub siab xim rendering Performance index (CRI> 90 lossis txawm Ra> 95) yog ib qho yooj yim kom tau nrog COB chips zoo. Qhov no txhais tau hais tias nws tuaj yeem pom cov xim tiag tiag ntawm cov khoom zoo dua, uas ua rau nws zoo meej rau cov chaw uas xav tau cov xim kom raug, xws li cov tsev khaws puav pheej, cov duab kos duab, cov khw muag khoom kim heev, khw muag khaub ncaws, tsev so, thiab tsev.
Qhov zoo tshaj plaws kom tshem tawm cov cua sov:COB nti yog txuas ncaj qha mus rau lub substrate, thiab lub substrate yog nyob ze koom rau lub downlight lub cua sov dab dej. Qhov no ua rau nws yooj yim dua rau cua sov kom khiav tawm sai dua thiab ncaj qha, uas yuav pab tau lub teeb kom ntev dua.
Me me, yooj yim los tswj lub teeb faib:Lub teeb ci yog ib chav tsev, yog li nws tuaj yeem ua tib zoo ua ke nrog lub khob iav lossis lub lens tswj lub kaum sab xis ntawm lub teeb emission. Qhov no ua rau lub teeb concentration zoo dua thiab pov tseg lub teeb tsawg dua.
