Umqondo Oyisisekelo Welensi
I-lens yenziwe ngokomthetho wokukhanyela ukukhanya. Ilensi isakhi esibonakalayo esenziwe ngento esobala njengengilazi, ikristalu, noma ezinye. Ilensi iyirefractor indawo yayo ecwebezelayo iyiziyingi ezimbili (ingxenye yendawo eyindilinga), noma eyindilinga (ingxenye yendawo eyindilinga) kanye nomzimba okhanyayo oyisicaba. Inesithombe sangempela kanye nesithombe esibonakalayo. Amalensi ngokuvamile angahlukaniswa abe izigaba ezimbili ezibanzi: ilensi eyi-concave ne-convex lens. Ingxenye emaphakathi ijiyile kunengxenye esemaphethelweni, ebizwa ngokuthi i-convex lens kuyilapho ingxenye emaphakathi izacile kunengxenye esemaphethelweni.
Amalensi e-LED ngokuvamile ama-silicone lens ngenxa yokuthi i-silicone imelana nezinga lokushisa eliphezulu futhi ingaphinda igeleze, ngakho ivamise ukupakishwa ngokuqondile kuma-chips e-LED. Ilensi evamile ye-silicone incane ngomthamo, 3-10mm ububanzi, futhi ilensi ye-LED ngokuvamile ihlotshaniswa eduze ne-LED, engasiza ekuthuthukiseni ukusebenza kahle kokukhishwa kokukhanya kwe-LED kanye nesistimu yokubona eshintsha inkambu yokukhanya. ukusatshalaliswa kwe-LED.
Ilensi ye-LED enamandla amakhulu noma isibonisi sisetshenziswa kakhulu ukuqoqa nokuqondisa ukukhanya kwemikhiqizo yomthombo wokukhanya obandayo we-LED yamandla amakhulu. Ilensi ye-LED enamandla amakhulu idizayina ijika lokusabalalisa ukukhanya ngokuya nge-engeli yama-LED ahlukene kunesethi yelensi ye-aspherical optical, futhi ikhuphula ukukhanya ukuze kuncishiswe ukulahlekelwa ukukhanya nokuthuthukisa ukusebenza kahle kokukhanya.
Mayelana nelensi ye-LED, sethemba ukuthi le ncazelo elandelayo izokusiza uqonde umehluko wento ngayinye yelensi ye-LED kanye nezinzuzo zamalensi e-LED.
I. Ukuhlukaniswa kwezinto ezibonakalayo zelensi ye-LED
1. Ilensi ye-Silicone
I-1) Ngenxa yokuthi i-silicone imelana nokushisa okuphezulu (futhi ingaphinda igeleze kabusha), ivame ukupakishwa ngokuqondile ku-chip ye-LED.
2) Ilensi ye-silicone evamile incane ngevolumu futhi inobubanzi obungu-3-10 mm.
2.PMMA ilensi
1) Ibanga le-Optical PMMA (i-polymethyl methacrylate, eyaziwa ngokuthi: i-acrylic)
2) Izinto zePlastiki, ezinezinzuzo zokusebenza kahle kokukhiqiza (zingagcwaliswa ngokubunjwa komjovo, ukukhishwa) kanye nokudluliswa okuphezulu (cishe ukungena okungu-93% ku-3mm ukushuba), kodwa futhi izinga lokushisa alikwazi ukudlula ama-80 ° C (ukushisa okuhlanekezela ukushisa 92 ° C )Amaphutha.
3.PC ilensi
1) I-Polycarbonate (PC) ye-Optical grade polycarbonate
2) Izinto zePlastiki, ezinezinzuzo zokusebenza kahle kokukhiqiza (zingagcwaliswa ngokubunjwa komjovo, ukukhishwa kwe-extrusion) kanye nokudluliswa okuphezulu (cishe ukungena okungu-89% ku-3mm ukushuba), kodwa futhi izinga lokushisa alikwazi ukudlula i-110 ° C (izinga lokushisa lokuhlanekezelwa kokushisa 135 ° C))
4. Ilensi yengilazi
I-Optical glass material, enezinzuzo zokudluliswa kokukhanya okuphezulu (ukungena okungu-97% ku-3mm ukushuba) kanye nokumelana nokushisa okuphezulu, kodwa okubi kwayo ukuthi isindayo ngevolumu, isesimweni esisodwa, intekenteke, kunzima ukufeza ukukhiqizwa ngobuningi, futhi iphansi. ukusebenza kahle kokukhiqiza, izindleko eziphezulu, njll.
II. Inzuzo yokusebenzisa lens LED
1. Kungakhathaliseki ukuthi ibanga lingakanani, i-lampshade (inkomishi ye-reflector) ayihluke kakhulu ku-lens. Ngokuphathelene nokufana, ilensi iphakeme kunesibonisi.
2. Umphumela wokusebenzisa i-lens encane ye-LED ingcono kune-lampshade ngoba isibani sesibani sifingqiwe nge-lens (futhi i-LED ngokwayo kufanele ibe ne-lens), bese igxiliswa nge-reticle, okwenza ububanzi obufanayo bokukhanyisa. iphuzu elikhudlwana futhi lichitha ukukhanya okuningi. Kodwa nge-lens ye-LED, kokubili ububanzi kanye ne-engeli yokukhanya yelensi kungaphathwa kahle.
