Umbono osisiseko weLens
I-lens yenziwe ngokomthetho wokukhanyela ukukhanya. Ilensi licandelo elibonakalayo elenziwe ngento ecacileyo njengeglasi, ikristale, okanye ezinye. Ilensi sisiqhankqalazi esinomphezulu ophinda-phindayo uyimiphezulu emibini engqukuva (inxalenye yomphezulu ongqukuva), okanye umphezulu ongqukuva (inxalenye yomphezulu ongqukuva) kunye nomzimba othe tyaba obonakalayo. Inomfanekiso wokwenyani kunye nomfanekiso wenyani. Iilensi zinokwahlulwa ngokubanzi zibe ziindidi ezimbini ezibanzi: ilens concave kunye neconvex lens. Indawo esembindini ijiyile kunendawo esekupheleni, ebizwa ngokuba yi-convex lens ngelixa indawo esembindini ibhityile kunendawo esekupheleni.
Iilensi ze-LED ngokubanzi ziilensi ze-silicone kuba i-silicone iyaxhathisa kubushushu obuphezulu kwaye inokuphinda iqhutyelwe, ke ihlala ipakishwe ngokuthe ngqo kwiitshiphusi ze-LED. I-lens ye-silicone ngokubanzi incinci ngomthamo, i-3-10mm ububanzi, kwaye i-lens ye-LED ihambelana ngokusondeleyo ne-LED, enokunceda ekuphuculeni ukukhanya okukhupha ukukhanya kwe-LED kunye nenkqubo yokukhanya etshintsha indawo yokukhanya. ukuhanjiswa kwe-LED.
I-lens ye-LED enamandla amakhulu okanye isibonisi sisetyenziselwa ukuqokelela kunye nokukhokela ukukhanya kwemveliso yomthombo wokukhanya obandayo we-LED. I-lens ye-LED ephezulu yamandla idiza ijika lokusabalalisa ukukhanya ngokuhambelana ne-angle yee-LED ezahlukeneyo kunokuba i-lens ye-aspherical optical iseti, kwaye ikhulise ukubonakaliswa kwe-optical ukunciphisa ilahleko yokukhanya kunye nokuphucula ukukhanya.
Malunga nelensi ye-LED, ndiyathemba ukuba le ngcaciso ilandelayo inokukunceda uqonde umahluko kwisixhobo ngasinye se-lens ye-LED kunye neenzuzo zelensi ye-LED.
I. Ukuhlelwa kwezinto eziphathekayo zelensi ye-LED
1. Ilensi yeSilicone
1) Ngenxa yokuba i-silicone iyamelana nokushisa okuphezulu (kwaye ingaphinda ifakwe kwakhona), idla ngokupakishwa ngokuthe ngqo kwi-chip ye-LED.
2) I-lens ye-silicone ngokubanzi incinci kumthamo kwaye inobubanzi be-3-10 mm.
2.PMMA ilensi
1) Ibakala le-Optical PMMA (i-polymethyl methacrylate, eyaziwa ngokuba yi: acrylic)
2) Izinto zePlastiki, ezinenzuzo yokusebenza kakuhle kwemveliso (zinokugqityezelwa ngokubunjwa kwenaliti, i-extrusion) kunye nokuhanjiswa okuphezulu (malunga ne-93% yokungena kwi-3mm ubukhulu), kodwa kwakhona ubushushu abunakudlula i-80 ° C (iqondo lokushisa lokuguqula ubushushu 92 ° C )Iintsilelo.
3.PC ilensi
1) I-polycarbonate yebakala le-Optical (PC) i-polycarbonate
2) Izixhobo zePlastiki, ezinenzuzo yokusebenza kakuhle kwemveliso (zinokugqityezelwa ngokubunjwa kwenaliti, i-extrusion) kunye nokuhanjiswa okuphezulu (malunga ne-89% yokungena kwi-3mm ubukhulu), kodwa kwakhona iqondo lobushushu alikwazi ukudlula i-110 ° C (iqondo lokushisa lokufudumala kwe-135 ° C))
4. Ilensi yeglasi
Izinto zeglasi ye-Optical, enezibonelelo zokuhanjiswa kokukhanya okuphezulu (ukungena kwe-97% kwi-3mm ubukhulu) kunye nokumelana nobushushu obuphezulu, kodwa ukusilela kwayo kukuba inobunzima bomthamo, ubume obunye, bubuthathaka, kunzima ukufikelela kwimveliso yobuninzi, kwaye iphantsi. ukusebenza kakuhle kwemveliso, ixabiso eliphezulu, njl.
II. Inzuzo yokusebenzisa i-lens ye-LED
1. Kungakhathaliseki ukuba umgama, i-lampshade (indebe ye-reflector) ayihluke kakhulu kwi-lens. Ngokuphathelele ukufana, i-lens iphezulu kune-reflector.
2. Isiphumo sokusebenzisa i-lens encinci ye-lens ye-LED ingcono kune-lampshade kuba isibane sesibane sigxininiswe nge-lens (kwaye i-LED ngokwayo kufuneka ibe ne-lens), kwaye emva koko igxininiswe yi-reticle, yenza uluhlu olufanayo lokukhanyisa. indawo enkulu kwaye ichitha ukukhanya okuninzi. Kodwa nge-lens ye-LED, zombini uluhlu kunye ne-angle yokukhanya kwe-lens inokuphathwa kakuhle.
