ChiiChip-on-Board ("COB") LEDs?
Chip-on-Board kana kuti "COB" inoreva kukwidziridzwa kweiyo isina mwenje LED chip yakanangana neiyo substrate (yakadai sesilicon carbide kana safiro) kugadzira LED arrays. Ma COB LED ane akati wandei mabhenefiti pamusoro pechikuru che LED tekinoroji, senge Surface Mounted Device ("SMD") LEDs kana Dual In-line Package ("DIP") LEDs. Kunyanya kukosha, tekinoroji yeCOB inobvumira kuwanda kwepamusoro-soro kweiyo LED array, kana izvo mainjiniya emwenje anoreva seyakagadziridzwa "lumen density". Semuyenzaniso, kushandisa COB LED tekinoroji pa10mm x 10mm square array zvinoguma ne38 times more LEDs zvichienzaniswa neDIP LED tekinoroji uye ka8.5 maLED akawanda zvichienzaniswa ne.SMD LEDtekinoroji (ona mufananidzo pazasi). Izvi zvinokonzera kusimba kwepamusoro uye kufanana kukuru kwechiedza. Neimwe nzira, kushandisa COB LED tekinoroji inogona kudzikisa zvakanyanya tsoka uye kushandiswa kwesimba kweiyo LED array uchichengeta kubuda kwemwenje nguva dzose. Semuyenzaniso, 500 lumen COB LED array inogona kuva diki kakawanda uye ichipedza simba shoma pane mazana mashanu lumen SMD kana DIP LED Array.
