Mu 2016, gulu la kafukufuku wa sayansi ndi ukadaulo ndi chitukuko lidapeza zotsatira zabwino pakutsika mtengo kwa gwero la kuwala kwa COB. Kutengera momwe amapangira, mabatani omwe amagwiritsidwa ntchito ndi gwero la kuwala kwa COB amakhala ndi makulidwe ambiri. Mabulaketi ambiri, zida zawo ndi aluminiyamu, ndipo pali mabatani amkuwa ndi ceramic. Nthawi zambiri, palibe mbali. Mabokosi omwe amagwiritsidwa ntchito mumikanda yophatikizika ya nyali ya LED ndi 10W, 100W, 500W ndi mabulaketi ena akulu. Zidazo zimakhala zamkuwa, ndipo mabataniwo amakhala ndi mapazi awiri ambali. LED ndi chipangizo cholimba cha semiconductor, chomwe chimatha kusintha magetsi kukhala kuwala. LED ndi ukadaulo wachitatu wowunikira pambuyo pa nyali za incandescent ndi nyali za fulorosenti. Lili ndi makhalidwe opulumutsa mphamvu, kuteteza chilengedwe, otetezeka komanso odalirika. Mikanda yofiirira imazindikira mtundu wa nyali wamsewu wa COB wopindika. Mtengo CRI > Kuwala kwa 80 kumaposa 190LM/W, ndipo kumatha kupangidwa m'magulu. Ili patsogolo pamakampani. Izi ndiye chisankho chabwino kwambiri chopangira zinthu zapamwamba kwambiri. Pakalipano, malo ake akuluakulu ogwiritsira ntchito mwina ndi awa: Popeza LED ndi thupi lowala lathyathyathya, kuwala kwake kumakhala kokwera kwambiri kuposa 120LM/W, yomwe ili yokwera kwambiri kuposa 100LM/W ya 70LM/W ya nyali wamba wa fulorosenti ndi T5. nyale. Kuwala kwapamwamba. Monga tonse tikudziwa, mtundu wa tchipisi ta LED umakhudza kwambiri mtundu wa ma CD otsika kapena zinthu zomaliza. Makasitomala ali ndi zofunikira zapamwamba pakukhazikika, kukhazikika, komanso kuwola kowala kwa tchipisi ta LED. Hua Chan nthawi zonse amakhalabe ndi luso komanso kukhathamiritsa kwaukadaulo wazinthu, kufika pamlingo waukadaulo wapadziko lonse lapansi, ndipo adalandira kuzindikira kwamakasitomala ambiri pamakampani. Purple kuwala mkanda monoma zomangamanga, mbiri yomanga gulu kunja khoma kuyatsa, kuwala ndi akunja kumuika nyumba, kuunikira m'nyumba m'deralo, zobiriwira malo kuyatsa, malonda khadi kuyatsa, chikhalidwe chachipatala ndi zina zapadera kuyatsa, mipiringidzo, ballroom ndi zosangalatsa malo m'mlengalenga kuyatsa. , ndi zina. Chip chamagetsi chamagetsi cholumikizidwa ndi kugwirizana kwa gawo lapansi kudzera pa chingwe chagolide choyang'ana mmwamba, ndipo gawo lamagetsi la chipangizocho choyang'ana pansi ndi lofanana ndi kutembenuza choyambirira, motero chimatchedwa “Chip chopindika ”The lolingana ma CD ndondomeko amatchedwa “Inverted ndondomeko ”. Pali njira ziwiri zopezera kuyatsa kwamphamvu kwa LED: imodzi ndikuyika chipangizo chimodzi champhamvu champhamvu cha LED, ndipo ina ndikugwiritsa ntchito zophatikizira zamitundu yambiri. Zakale, ndi chitukuko cha teknoloji ya chip, kukula kumawonjezeka ndipo khalidwe limakhala bwino, ma LED amphamvu kwambiri amatha kutheka kupyolera mu madalaivala akuluakulu amakono, koma nthawi yomweyo, adzakhala ochepa ndi kukula kwa chip. Chotsatiracho chimakhala ndi kusinthasintha kwakukulu komanso kuthekera kwachitukuko. Chiwerengero cha tchipisi chingasinthidwe molingana ndi zowunikira zosiyanasiyana. Nthawi yomweyo, imakhala ndi magwiridwe antchito okwera mtengo, kupangitsa kuyika kwa kuphatikiza kwa LED kukhala imodzi mwamagawo ofunikira pakuyika kwa LED. Kuyambira 2009, kuti athyole mu ulamuliro wa opanga akunja kwa munda uwu, Xiong Daxi anatsogolera gulu ndi thandizo lamphamvu la Chinese Academy of Sciences, Jiangsu, Suzhou, ndi madera apamwamba -chatekinoloje, moganizira kafukufuku ndi chitukuko ndi mafakitale a magwero apadera a kuwala kwa LED. M'malo mwa R & D kupanga ndi kupanga matekinoloje, tayang'ana kwambiri kafukufuku ndi chitukuko ndi njira zosiyana, ndipo tapindula kwambiri. Mikanda yofiirira ya LED inverted gold -wire chip -level ma CD. Kutengera umisiri wopindika wa chip, kutengera kachitidwe kamtundu wa chip, ukadaulo wa waya wagolide wowotcherera wachepetsedwa, ndikungotsala tchipisi ndi kuwala ndi ufa wa fulorosenti ndi ntchito zina.
