C Philips LED Nyali Mikanda OB Packaging Kodi Amakondedwa ndi Msika?

Chifukwa chiyani ma CD a COB amakondedwa ndi msika? Phukusi la COB (CHIP-BOARD) la mikanda ya nyali ya LED lapeza zinthu zambiri pamsika pano. Kuonjezera apo, mphamvu ndi mtengo wa kupanga ndi kupanga ndizosapeweka. Kumsika, zotsalira ndi mfumu, ndipo ndi mfundo yopezera ndalama. Tiyeni tifotokozere kumtunda kwa COBLED kuchokera pakupanga ndi kupanga ndi mtengo wake. Kugwira ntchito bwino kwa ma CD a COB pakupanga ndikofunika kwambiri pankhani yomatira, kugawikana, kutulutsa, komanso kuyika. Poyerekeza ndi zinthu zachikhalidwe za SMD, zolemba zakale zopangira zinthu zopangira ndi kupanga zimatengera 10% ya mtengo wazinthu, ndipo zomalizazi sizimawerengera 15%. Pankhani ya mtengo, kutenga nyali ya dzuwa ya 1.2M monga chitsanzo, pogwiritsa ntchito gwero la kuwala kwa COBLED, mtengo wa nyali yonse ya 1600LM ukhoza kuchepetsedwa ndi 25%, 1800LM ikhoza kuchepetsedwa ndi 29%, ndipo 2000LM ikhoza kuchepetsedwa ndi 33% . Izi ndizopindulitsa kwambiri kuti kuyatsa kwa LED kufalikira posachedwa. Sizingatheke kupanga nokha. Gwero la kuwala kwa COBLED kuposa ma LED achikhalidwe a SMD, potengera kukana kwamafuta komanso mtundu wopepuka. SMD ma CD ma CD kukana matenthedwe ndi: chipsolid crystal gluesolder jointstin pastecopper foilinsulation layeraluminum, ndi COB ma CD matenthedwe kukana ndi: chipsolid crystal gluealuminium zakuthupi, kotero zitha kudziwika kuti COB Kukana kutentha kwa ma CD kumatsika kwambiri kuposa ma CD a SMD, zomwe zawonjezera moyo wautumiki wa LED. Chifukwa ma CD a SMD ndichifukwa chake, momwe chigambacho chimamangirira zida zingapo zosiyana pa bolodi la PCB kuti zipange gawo la gwero la kuwala kwa LED. Njira yamtunduwu silepheretsa vuto la kuwala, kuwala ndi mthunzi. COBLED ndi magwero ophatikizika ophatikizika. Kawonedwe ndi kuyanjana kosavuta kwachepetsedwa. Kutayika kwa refraction kuwala kumachepetsedwa. Ndi bwino ndi kuwala khalidwe. Ziribe kanthu pakuwona mtengo ndi kugwiritsa ntchito, kuyika kwa COB ndi njira yothandiza yothetsera kukana kutentha kwakukulu komanso zovuta zotsika mtengo pamapangidwe omwe alipo a SMD. Chiwerengero cha ma COB onyamula ma LED pamsika chawonjezeka pang'ono.
