Ubakaki we-LED, isisekelo esiphansi seUbuhlalu besibani se-LEDngaphambi kokupakisha.Ngesisekelo sobakaki we-LED, i-chip igxilile, ama-electrode amahle futhi angalungile ashiselwe, bese i-adhesive yokupakisha isetshenziselwa ukwakha iphakheji.

Ubakaki we-LED ngokuvamile wenziwa ngethusi (futhi insimbi, i-aluminium, i-ceramics, njll.).Ngenxa ye-conductivity enhle yethusi, kuzoba nomkhondo ngaphakathi kuwo ukuxhuma ama-electrode ngaphakathi kobuhlalu besibani se-LED.Ngemuva kokuthi ubuhlalu besibani se-LED bupakishwe futhi bukhiwe, ubuhlalu besibani bungasuswa kubakaki.Izinyawo zethusi emikhawulweni yomibili yobuhlalu besibani ziba ama-electrode aqondile futhi angemuhle wobuhlalu besibani, asetshenziselwa ukushisela izibani ze-LED noma eminye imikhiqizo eqediwe ye-LED.

Imodeli kanye nokucaciswa

Ngokuvamile, abakaki be-LED bafakwa ngokuqondile kubakaki be-LED, kubakaki be-piranha be-LED, abakaki be-LED be-patch kanye nabakaki be-LED bamandla aphezulu:

Ngokuvamile, kukhona okufakwayo okuningi okuqondile, okuhlanganisa i-02 enemilenze emifushane, i-03 ene-angle enkulu ebomvu ephuzi, i-04LD enokukhanya okuluhlaza okwesibhakabhaka okumhlophe, i-A5, i-A6 enokukhanya okumhlophe, i-A7, i-A8 enenkomishi enkulu ngezansi, i-06 enekhanda eliyisicaba, 09 ngemibala emibili nemithathu, njll;

Ubukhulu bobakaki be-LED bunomthelela othile ekukhanyeni okukhanyayo noma i-engeli ekhanyayo, futhi ukukhishwa kwayo kokushisa kunobudlelwane obuqondile nezici zokukhanya nempilo yesevisi ye-LED.

I-chip ye-LEDimakethe yokusekela UKUBONA USIDE 335 008 020 010, AMANDLA APHAKEME TO220 LUXEON 1-7W, njll., ngoba imininingwane yabo ayihlanganisiwe, kunezincazelo eziningi ezikhethekile.

Ukwahlukanisa

Ngokusho kwalesi simiso, kunezinhlobo ezimbili: uhlobo lokugxila (oluphethe inkomishi) kanye ne-angle enkulu yohlobo lwe-astigmatic Isibani (isibambi sekhanda eliyisicaba).Isibonelo: A. 2002 inkomishi/ikhanda eliyisicaba: lolu hlobo lokusekela ngokuvamile lwenziwa ngezinto ezine-engeli ephansi nezimfuneko, futhi ubude balo bephinikhodi bufushane ngo-10mm kunezinye izisekelo.Isikhala samaphini singu-2.28mm.B. 2003 inkomishi/ikhanda eliyisicaba: ngokuvamile lisetshenziselwa φ Elambuni elingaphezu kuka-5, ubude bephinikhodi obuveziwe bungu+29mm futhi – 27mm.Isikhala samaphini singu-2.54mm.C. 2004 inkomishi/ikhanda eliyisicaba: elisetshenziselwa ukwenza φ 3 Lamp.Ubude bephinikhodi nesikhala ziyefana nalezo zikabakaki ka-2003.D. Isetshenziselwa ukwenza izibani eziluhlaza okwesibhakabhaka, ezimhlophe, eziluhlaza okumsulwa kanye nezinsomi, ezingashiselwa ngemigqa ekabili futhi zibe nezinkomishi ezijulile.E. 2006: Zombili izigxobo ziwuhlobo lwekhanda eliyisicaba, elisetshenziselwa isibani esikhanyayo, ukulungisa i-IC nokushisela imigqa eminingi.F: 2009: Isetshenziselwa ukwenza isibani esinemibala emibili.Okubili kungalungiswa enkomishini, futhi izikhonkwane ezintathu zilawula i-polarity.G: 2009-8/3009: Isetshenziselwa ukwenza ilambu le-tricolor.Ama-chips amathathu namaphinikhodi amane angalungiswa enkomishini.H: 724-B/724-C: isetshenziswa njengosekelo lwepiranha.
