1W 3W 5W siab zog LED lens khoom hom kev taw qhia
Cov khoom siv ntawm high-power LED teeb hlaws lo ntsiab muag
1. High-power LED teeb hlaws silicone lens
(1) Vim tias qhov kub thiab txias tsis kam ntawm silica gel (nws tseem tuaj yeem rov ua dua), nws feem ntau siv los ncaj qha pob ntawm LED teeb hlaws nti.
(2) Feem ntau, lub lens silicone yog me me, nrog txoj kab uas hla ntawm 3=10mm.
2. High-power LED teeb hlaws PMMA lens
(1) Optical qib PMMA (polymethyl methacrylate, feem ntau hu ua: acrylic).
(2) Cov ntaub ntawv yas, qhov zoo: kev ua haujlwm siab (tuaj yeem ua tiav los ntawm kev txhaj tshuaj molding thiab extrusion); siab transmittance (li 93% thaum lub thickness yog 3 hli); Qhov tsis zoo: qhov kub tsis tuaj yeem siab tshaj 80 ° (qhov kub ntawm thermal deformation yog 92 Siv).
High-power LED teeb hlaws dai
3. High-power LED teeb hlaws PC lens
(1) Optical qib khoom Polycarbonate (hu ua PC) polycarbonate.
(2) Cov ntaub ntawv yas, qhov zoo: kev ua haujlwm siab (tuaj yeem ua tiav los ntawm kev txhaj tshuaj molding thiab extrusion); me ntsis txo lub teeb transmittance (li 89% thaum lub thickness yog 3 hli); Qhov tsis zoo: qhov kub tsis tuaj yeem tshaj 110 ° (thermal deformation kub 135 degrees).
4. High-power LED teeb hlaws iav lens
Optical iav khoom
Qhov zoo: lub teeb xa hluav taws xob siab (97%), kub tsis kam;
Disadvantages: ib leeg zoo, tsis yooj yim, tsis yooj yim mus cuag loj ntau lawm, tsis muaj ntau lawm efficiency, siab nqi. Txawm li cas los xij, tam sim no, cov tuam txhab lag luam hauv tsev tsawg tsawg tau pib tsim cov txheej txheem iav molding, siv cov pwm los yaj thiab cam khwb cia iav lo ntsiab muag, uas tuaj yeem tsim cov lo ntsiab muag ntawm ntau yam duab thiab qhov chaw tshwj xeeb.
Moulded ntau lawm, cov khoom zoo sib xws, siab precision, thiab tuaj yeem txhim kho kev tsim khoom, txo tus nqi ntawm cov iav lo ntsiab muag, ua ke nrog cov yam ntxwv ntawm lub teeb pom kev zoo, iav lo ntsiab muag tau khi los ua qhov hloov pauv ntawm cov khoom siv kho qhov muag muaj zog LED teeb hlaws. lo ntsiab muag khoom siv deev. Txawm li cas los xij, tus nqi ntawm cov khoom siv ntau lawm tam sim no siab, thiab nws yog qhov nyuaj rau kev nyiam nyob rau lub sijhawm luv.
Tsis tas li ntawd, iav yog qhov yooj yim dua li PMMA thiab PC cov ntaub ntawv, thiab xav tau kev tshawb fawb thiab kev tshawb nrhiav ntau dua. Rau cov txheej txheem kev txhim kho uas tuaj yeem ua tiav tam sim no, cov khoom tsis yooj yim ntawm cov iav tuaj yeem tsuas yog txhim kho los ntawm txheej txheej lossis tempering kho. , lub teeb transmittance ntawm iav lo ntsiab muag yuav raug txo, tab sis nws tseem yuav nyob deb ntau dua li lub teeb transmittance ntawm zoo tib yam optical yas lo ntsiab muag. Yog li ntawd, lub zeem muag ntawm iav lens yuav dav dua.
