LED lens khoom hom
Silicone lens a. Vim hais tias silicone yog resistant mus rau high kub (thiab muaj peev xwm yuav reflowed), nws yog feem ntau siv rau pob teeb ntawm LED chips. b. Lub lithicone general lens yog me me hauv lub ntim thiab 3-10 hli inch.
PMMA lens a. Optical qib PMMA (polymethyl methacrylate, nquag paub: acrylic). b. Cov ntaub ntawv yas, qhov zoo: cov khoom ua tau zoo heev (muaj peev xwm ua tiav ntawm kev txhaj tshuaj molding, extrusion); high transmittance (93% penetration ntawm 3mm thickness); Disadvantages: qhov kub tsis tshaj 80 ° (kub kub qhov siab kub 92 degrees).
PC lens a. Optical qib Polycarbonate (PC) polycarbonate. b. Cov ntaub ntawv yas, qhov zoo: cov khoom ua tau zoo heev (muaj peev xwm ua tiav ntawm kev txhaj tshuaj molding, extrusion); lub teeb hloov ntawm kab mob yog me ntsis qis dua (qhov nkag mus txog li 89% ntawm 3mm thickness); Disadvantage: qhov kub tsis siab tshaj 110 ° (tshav kub kub ntawm qhov ntsuas kub 135).
Iav lens Optical iav khoom, qhov zoo: siab lub teeb hloov (97%), kub ua hauj lwm, thiab lwm yam .; Disadvantages: ib hom, tsis muaj zog, tsis yooj yim kom ua tau ntau lawm, ua kom tsis muaj zog, cov nqi siab. Txawm li cas los, tam sim no, tsawg heev tuam txhab nyob rau hauv Suav teb tau pib tsim cov iav molding, thiab siv iav casting los ua iav lo ntsiab muag, uas muaj peev xwm tsim lo ntsiab muag ntau thiab cov chaw tshwj xeeb. Tsis tas li ntawd, pwm ntau lawm, cov khoom muag zoo, siab dua, thiab muaj peev xwm ua kom zoo dua qub, ua kom tsis txhob muaj cov iav lo ntsiab muag, ua ke nrog lub teeb siab loj, iav lens yog txia ua cov khoom siv hluav taws xob zoo tshaj . Txawm li cas los xij, tus nqi tam sim no ntawm cov khoom siv rau kev lag luam no siab heev thiab nws tsis yooj yim rau qhov nrov nrov nyob rau lub sij hawm luv luv.
Tsis tas li ntawd, cov kev tsis zoo ntawm cov iav piv rau PMMA thiab PC cov ntaub ntawv muaj ntau lub zog, thiab kev tshawb nrhiav thiab kev tshawb nrhiav ntxiv. Nyob rau hauv txoj kev txhim kho tam sim no uas muaj peev xwm pom tau tam sim no, cov cuab yeej tsis khov kho ntawm lub khob tsuas tuaj yeem kho kom zoo los ntawm kev kho los yog cov tshuaj tiv thaiv, tab sis tom qab cov kev kho mob Cov kab mob ntawm lub iav lens yuav raug txo kom tsawg, tab sis nws tseem yuav loj tshaj hais tias ntawm qhov dog dig optical yas lens. Yog li ntawd, lub prospect ntawm iav lo ntsiab muag yuav txawm dav dua.
