Yana da hoto na gaske da hoto mai kama-da-wane. Za'a iya raba ruwan tabarau zuwa rukuni biyu da yawa: cons ruwan tabarau da ruwan tabarau na convex. Bangaren tsakiya yana da kauri fiye da ɓangaren gefen, wanda ake kira lens mai ɗaukar hoto yayin da ɓangaren tsakiya ya fi bakin ciki.
Ruwan tabarau na LED gabaɗaya ruwan tabarau na silicone ne saboda silicone yana da juriya ga yanayin zafi kuma ana iya sake kwararawa, don haka yawanci ana tattara shi kai tsaye akan kwakwalwan LED. Babban ruwan tabarau na silicone yana da ɗan ƙaramin ƙarami, 3-10mm a diamita, kuma ruwan tabarau na LED gabaɗaya yana da alaƙa da LED, wanda zai iya taimakawa haɓaka haɓakar hasken wutar lantarki na LED da tsarin gani wanda ke canza filin haske. rarraba LED.
Ana amfani da ruwan tabarau mai ƙarfi na LED ko mai nuna haske don tattarawa da jagorantar haske na samfuran tushen hasken sanyi mai ƙarfi na LED. Babban iko LED ruwan tabarau yana tsara madaidaicin rarraba haske bisa ga kusurwar LEDs daban-daban maimakon saitin ruwan tabarau na gani na aspherical, kuma yana haɓaka hangen nesa don rage hasara mai haske da haɓaka ingantaccen haske.
Game da ruwan tabarau na LED, fatan bayanin mai zuwa zai taimaka muku fahimtar bambanci akan kowane abu na ruwan tabarau na LED da fa'idodin ruwan tabarau na LED.
I. Rarraba kayan aikin ruwan tabarau na LED
1. Silicone ruwan tabarau
1) Saboda silicone yana da juriya ga yanayin zafi (kuma ana iya sake kwararawa), yawanci ana tattara shi kai tsaye akan guntun LED.
2) Babban ruwan tabarau na silicone yana da ɗan ƙaramin ƙaranci kuma yana da diamita na 3-10 mm.
2.PMMA ruwan tabarau
1) Matsayin gani PMMA (polymethyl methacrylate, wanda aka fi sani da: acrylic)
2) Filastik kayan, wanda ke da abũbuwan amfãni na samar da inganci (za a iya kammala ta allura gyare-gyare, extrusion) da kuma high transmittance (game da 93% shigar azzakari cikin farji a 3mm kauri), amma kuma yawan zafin jiki ba zai iya wuce 80 ° C (zafi murdiya zazzabi 92). ° C )Gajewa.
3. PC ruwan tabarau
1) Polycarbonate (PC) polycarbonate
2) Filastik kayan, wanda ke da abũbuwan amfãni na samar da inganci (za a iya kammala ta allura gyare-gyare, extrusion) da kuma high transmittance (game da 89% shigar azzakari cikin farji a 3mm kauri), amma kuma yawan zafin jiki ba zai iya wuce 110 ° C (zafi murdiya zazzabi 135 ° C). C))
4. Gilashin ruwan tabarau
Kayan gilashin gani, wanda ke da fa'idodin watsa haske mai girma (97% shigar a cikin kauri 3mm) da tsayin daka na zafin jiki, amma rashin amfaninsa shine cewa yana da nauyi a cikin girma, guda ɗaya a cikin sifa, mai rauni, mai wahala don cimma samar da taro, da ƙarancin ƙarfi. ingancin samarwa, tsada mai tsada, da sauransu.
II. Amfanin amfani da ruwan tabarau na LED
1. Ko da kuwa nisa, fitilar fitila (kofin nuni) bai bambanta da ruwan tabarau ba. Dangane da daidaituwa, ruwan tabarau ya fi mai haskakawa.
2. Tasirin yin amfani da ƙaramin kusurwa na LED ruwan tabarau ya fi lampshade kyau saboda an ɗora fitilun ta hanyar ruwan tabarau (kuma LED ɗin kanta dole ne ya kasance da ruwan tabarau), sannan a tattara shi ta hanyar tsintsiya, wanda ke yin daidaitaccen kewayon mai haskakawa. nuna girma da ɓata haske mai yawa. Amma tare da ruwan tabarau na LED, duka kewayon da kusurwar hasken ruwan tabarau za a iya sarrafa su da kyau.
