Pfungwa Yekutanga yeLens
Iyo lens inogadzirwa maererano nemutemo wechiedza refraction. Lens inhengo yemaziso yakagadzirwa nechinhu chakajeka segirazi, crystal, kana zvimwe. Iyo lens irefractor ine refractive surface ine maviri spherical surfaces (chikamu chespherical surface), kana spherical surface (chikamu chespherical surface) uye muviri wakatsetseka wakajeka. Iine mufananidzo chaiwo uye mufananidzo chaiwo. Malenzi anogona kazhinji kukamurwa kuita mapoka maviri akafara: concave lens uye convex lens. Chikamu chepakati chakakora kudarika chikamu chekumucheto, chinodaidzwa kuti convex lenzi apo chikamu chepakati chakatetepa kupfuura chikamu chekumucheto.
Malenzi e LED anowanzo silicone lenzi nekuti silicone inoshingirira kune tembiricha yakakwira uye inogona zvakare kuyerera, saka inowanzoiswa yakananga pa LED machipisi. Iyo general silicone lens idiki muhukuru, 3-10mm muhupamhi, uye iyo LED lens inowanzo shamwaridzana neiyo LED, iyo inogona kubatsira kuvandudza mwenje-emitting kushanda kweiyo LED uye optical system inoshandura mwenje munda. kugoverwa kwe LED.
Iyo yakakwirira-simba re LED lens kana ratidziro inonyanya kushandiswa kuunganidza uye kutungamira mwenje wepamusoro-simba LED inotonhora sosi zvigadzirwa. Iyo yepamusoro-simba LED lens inogadzira mwenje wekugovera curve zvinoenderana nekona yeakasiyana maLED pane kuseti aspherical optical lens, uye inowedzera kupenya kwemaziso kuderedza kurasikirwa kwechiedza uye kunatsiridza kushanda kwechiedza.
Nezve lenzi ye LED, vimba kuti tsananguro inotevera inokubatsira iwe kunzwisisa mutsauko pane imwe neimwe zvinhu zve LED lens uye zvakanakira LED lens.
I. The material classification ye LED lens
1. Silicone lenzi
1) Nekuti silicone inopesana nekupisa kwakanyanya (uye inogona zvakare kufambiswazve), inowanzoiswa yakananga pa LED chip.
2) Iyo general silicone lens idiki muhukuru uye ine dhayamita ye3-10 mm.
2.PMMA lenzi
1) Optical giredhi PMMA (polymethyl methacrylate, inowanzozivikanwa se: acrylic)
2) Zvishandiso zvepurasitiki, zvine zvakanakira kugadzirwa zvakanaka (zvinogona kupedzwa nejekiseni kuumba, extrusion) uye yakakwirira transmittance (inenge 93% yekupinda pa3mm ukobvu), asiwo tembiricha haigone kudarika 80 ° C (kupisa kunokanganisa tembiricha 92. ° C )Kukanganisa.
3.PC lenzi
1) Optical giredhi Polycarbonate (PC) polycarbonate
2) Zvigadzirwa zvepurasitiki, zvine zvakanakira kugadzirwa zvakanaka (zvinogona kupedzwa nejekiseni kuumba, extrusion) uye yakakwirira transmittance (inenge 89% yekupinda pa 3mm ukobvu), asiwo tembiricha haigone kudarika 110 ° C (kupisa kushatisa tembiricha 135 ° C))
4. Girazi lens
Optical glass material, ine mabhenefiti ehigh light transmittance (97% kupinda pa3mm ukobvu) uye yakakwira tembiricha kuramba, asi chakashata ndechekuti inorema muhukuru, isina kurongeka, isina kusimba, yakaoma kuwana kugadzirwa kwakawanda, uye yakaderera. kushanda zvakanaka kwekugadzira, kudhura kwakanyanya, nezvimwe.
II. Zvakanakira kushandisa LED lens
1. Pasinei nechekure, mwenje wemwenje (reflector cup) hauna kunyanya kusiyana nelens. Panyaya yekufanana, iyo lens inopfuura iyo reflector.
2. Mhedzisiro yekushandisa kona diki ye LED lens iri nani pane mwenje wemwenje nekuti mwenje wemwenje wakadzikiswa kuburikidza nelens (uye iyo LED pachayo inofanirwa kunge ine lens), uye yobva yaiswa nereticle, ichiita iyo yunifomu huwandu hweinovhenekera. poindi hombe uye kutambisa chiedza chakawanda. Asi neiyo LED lens, ese ari maviri chiyero uye kona yekuvhenekera kwelens inogona kubatwa zvakanaka.
