Zintoni iiIi-LED zeChip-on-Board ("COB")?
I-Chip-on-Board okanye "COB" ibhekiselele ekufakweni kwe-chip ye-LED engenanto ekudibaneni ngokuthe ngqo kunye ne-substrate (efana ne-silicon carbide okanye isafire) ukuvelisa uluhlu lwe-LED. Ii-LED ze-COB zinenani leenzuzo ngaphezu kobuchwepheshe be-LED obudala, njenge-Surface Mounted Device ("SMD") ii-LED okanye ii-LED ze-Dual In-line Package ("DIP"). Okona kubalulekileyo, itekhnoloji ye-COB ivumela ukupakisha okuphezulu kakhulu koluhlu lwe-LED, okanye zeziphi iinjineli zokukhanya ezibhekisa kuyo njengokuphuculwa kwe-lumen density. Ngokomzekelo, ukusebenzisa iteknoloji ye-COB ye-LED kwi-10mm x 10mm yesikwele isiphumo se-38 amaxesha amaninzi e-LED xa kuthelekiswa nobuchwepheshe be-DIP ye-LED kunye namaxesha angama-8.5 ngaphezulu kwee-LED xa kuthelekiswa no.SMD LEDiteknoloji (jonga umzobo ongezantsi). Oku kubangela ukuqina okuphezulu kunye nokufana okukhulu kokukhanya. Kungenjalo, ukusebenzisa itekhnoloji ye-COB ye-LED kunokunciphisa kakhulu unyawo kunye nokusetyenziswa kwamandla kuluhlu lwe-LED ngelixa ugcina ukukhanya okuphuma rhoqo. Umzekelo, uluhlu lwe-500 lumen COB LED lunokuba luncinci amaxesha amaninzi kwaye lusebenzise amandla angaphantsi kakhulu kune-500 lumen SMD okanye i-DIP ye-LED Array.
