He aha ke ʻano o ka Luminous Diode

Hoʻohana nui ʻia ka diode kukui a loaʻa ke kumukūʻai kūʻai kiʻekiʻe. Hiki ke hoʻohana ʻia ma nā huahana uila, kukui, kalena, kalena, nā kukui alanui, nā mea lapaʻau, etc. ʻO kaʻu mea e makemake ai e wehewehe i kēia lā, ʻo ia kekahi o nā waiwai kumu o ke kukui emitting diode. 1. Power LED knot wela a me ka wela wela ma na au like ole noiʻi noiʻi. Ana e nā waihoʻoluʻu like ʻole o ke kala LED ka wela a me ke kūpaʻa wela ma lalo o nā au hoʻokele like ʻole. (1) Ua ʻoi aku ka nui o nā kumu kūʻai wela o nā kala like ʻole o nā LED me ka piʻi ʻana o ke au hoʻokele. 2. Ma waena o lākou, i ka wā o ka Blu -ray a me ke kukui keʻokeʻo LED e pili ana i nā mea Ingan, ke piʻi wikiwiki nei ke kū'ē wela i ka wā i emi iho ai ka helu i kēia manawa; ʻAʻole hoʻololi ʻia nā kala ʻē aʻe LED thermal resistance e like me ka hoʻololi ʻana o kēia manawa. 3. Piʻi pū ka wela o ka knot me ka piʻi ʻana o ke au hoʻokele. 4. Hoʻonui ʻia ka hoʻokele wela o kēia manawa; 1. Manaʻo ka ʻikepili e like me ka piʻi ʻana o ke kaʻa o kēia manawa, ʻo ka hopena squeezing o kēia manawa o ke au o loko o nā pahu kukui LED e hoʻemi i ka pono o ka puka kukui (hōʻemi i ka pūhui radiation), e alakaʻi ai i nā knots. ʻO ka piʻi ʻana o ka mahana, a ʻo ka piʻi ʻana o ka mahana e hoʻololi i ka pae alakaʻi wela o nā pahu kukui LED. Ua aʻo kekahi mau pūʻulu i ka GAN thermal conductivity mai 2.05W/(CM ·K) Hāʻule i 1.75W/(CM ·K); ua aʻo ʻia nā mea ʻē aʻe i ka mahana o ka conduction wela GAN mai 2.0W/(CM ·k) Hāʻule i 1.6W/(CM ·K). ʻO ka mea ʻē aʻe, ʻo ka emi ʻana o ka coefficient mehana o ka mea e kaohi ai i ka conductivity thermal o nā kukui kukui LED, a hoʻomaikaʻi hou i ka mahana o nā kukui kukui LED. Ma kēia ʻano, e hana ʻo ia i kahi pōʻai ʻino. Eia kekahi, ʻo ka nui o nā au e hoʻololi i ka nalowale ma waena o nā papa hoʻopili o nā kukui kukui LED a me ka degeneration o nā welds welded, kahi e piʻi ai ka mahana o nā kukui kukui LED. ʻO ka mea i luna ke ʻano kumu o ka diode luminous.
