Mavalidwe Okhazikika a LED Ndiosiyana Ndi Ma LED Otembenuzidwa

Kusiyana pakati pa mtundu wa LED ndi LED inverted (1). Solid crystal: Kachip kakang'ono ka kuyika kovomerezeka kumatengera guluu wotenthetsera mkati mwa dontho lamkati la bulaketi lolowetsedwa kuti likonze chip. Njira ya kristalo imagwirizanitsidwa ndi maziko a bracket, ndipo maziko a bracket palokha nthawi zambiri ndi zinthu zamkuwa zomwe zimakhala ndi matenthedwe apamwamba; (2). Mzere wowotcherera: Mawonekedwe a tchipisi tating'ono nthawi zambiri amakhala ang'onoang'ono ndipo kutentha kumakhala kochepa, kotero kutentha kumakhala kochepa, kotero kumakhala kochepa, kotero kumakhala kochepa. Choncho Gwiritsani maelekitirodi zabwino ndi zoipa kuti welded mmodzi φ0.8 φWaya wagolide wa 0.9mil wolumikizidwa ndi ma elekitirodi abwino ndi oyipa a bulaketi; Kuyendetsa kwa chip chamagetsi nthawi zambiri kumakhala pamwamba pa 350mA, ndipo kukula kwa chip kumakhala kwakukulu. Choncho, pofuna kutsimikizira kufanana ndi kukhazikika kwamakono mu jakisoni wa chip, nthawi zambiri zimakhala pamutu komanso zoipa za chip. Awiri amawotcherera pakati pa mlingo ndi mzati wolimba mtima wa bulaketi ndi bulaketi φ1.0 φMzere wagolide wa 1.25mil; (3). Kusankha ufa wa fluorescent: tchipisi tating'onoting'ono nthawi zambiri timayendetsa mafunde pafupifupi 20mA, pomwe tchipisi tamagetsi olowera nthawi zambiri chimakhala pafupifupi 350mA. Chifukwa chake ufa wotchuka wa fulorosenti pamsika ndi WAG. YAG yokha ndi pafupifupi 127 C ndi kukana kutentha kwambiri. Chip chikayatsidwa, kutentha (TJ) kudzakhala kokwera kwambiri kuposa kutentha uku. Choncho, pamene kutentha kwa kutentha sikuli bwino, ufa wa fulorosenti ndi wautali. Kuchepetsa nthawi yokalamba kumakhala koopsa, kotero tikulimbikitsidwa kugwiritsa ntchito silicate fulorosenti ufa ndi bwino kutentha kukana pa ma CD ma CD; (4). Kusankha kwa collagen: tchipisi tating'onoting'ono tokhala ndi tchipisi tating'ono Imatha kukwaniritsa zosowa zamapaketi; ndipo chipangizo chamagetsi cholowera chimakhala ndi kutentha kwakukulu ndipo chiyenera kutsekedwa ndi silikoni; kuti mufanane ndi refractive index of the sapphire substrate posankha silikoni, tikulimbikitsidwa kusankha cholozera chapamwamba kwambiri ( > 1.51). Pofuna kupewa refractive index kuti asachepetse mbali yovuta ya chiwonetsero chonse, kuwala kwakukulu kumatayika mkati mwa colloid yonyamula; panthawi imodzimodziyo, kusungunuka kwa silicone ndi kwakukulu, ndipo kupsinjika kwa kutentha kumakhala kochepa kwambiri kuposa utomoni wa epoxy poyerekeza ndi epoxy resin kuposa epoxy resin. Pogwiritsa ntchito, amatha kugwira ntchito yabwino yotetezera mu chip ndi mzere wa golide, womwe umathandizira kupititsa patsogolo kudalirika kwa mankhwala onse; The njira encapsulation, ndi pa inverted mphamvu Chip ma CD ndondomeko, chifukwa ntchito m`mabulaketi lathyathyathya mutu, pofuna kuonetsetsa yunifolomu lonse fulorosenti ufa, tikulimbikitsidwa kugwiritsa ntchito ndondomeko conformal ❖ kuyanika; (6). Mapangidwe a pulasitiki: Positive chip nthawi zambiri amagwiritsidwa ntchito mu nkhungu kudzaza utomoni wa epoxy ndikuyika bulaketi mu njira yolimbitsa kutentha kwambiri; pamene chipangizo champhamvu cholowera chimafunika kuthiriridwa pang'onopang'ono kuchokera kumodzi mwa ma pores olowa kuchokera ku mandala. Njira yodzaza, panthawi yodzaza, ntchitoyo iyenera kukonzedwa bwino kuti ipewe kuphika, ming'alu, zosanjikiza ndi zochitika zina mutatha kuphika; (7). Mapangidwe a kutentha: Tchipisi zabwino nthawi zambiri zimakhala zopanda kuzizira kowonjezera; ndi mphamvu yolowera mphamvu Chip nthawi zambiri chimafunika kuwonjezera mbale yoziziritsira kutentha pansi pa bulaketi. Muzochitika zapadera, kuwonjezera chowotcha pambuyo pa gawo lapansi la kutentha kwa kutentha kwa kutentha; popangira mawotchi opangira ma aluminium substrates, tikulimbikitsidwa kugwiritsa ntchito kutentha kwa chitsulo chotenthetsera ndi mphamvu ya mphamvu ya mphamvu.
