Lub hauv paus ntsiab lus ntawm LED diffuser phaj yog dab tsi? Yuav siv LED diffuser li cas?
Mar 17, 2022
LED diffuser is a chemical or physical method that uses the physical imagination of refraction, reflection and scattering when light encounters two media with different refractive indices on the way. Add inorganic or organic light diffusing agents to the base, or artificially adjust the light through the array arrangement of micro-features on the surface of the substrate, so that the light can be refracted, reflected, and scattered in different directions, and then change the travel path of the light to complete the incident light charge. The diffused color acts as an optical diffuser, and the LED diffuser plate is widely used in liquid crystal display, LED lighting and imaging display systems. The following editor will introduce the principle of LED diffusion plate and how to use LED diffusion plate?
Dab tsi yog lub hauv paus ntsiab lus ntawm LED diffuser
1. Ib txwm LED diffuser
Cov tsoos LED diffuser phaj tsuas yog siv cov khoom siv tshuaj raws li cov khoom tawg hauv cov khoom siv ntawm LED diffuser phaj, kom lub teeb tsis tu ncua refracted, reflected thiab tawg nyob rau hauv ob xov xwm nrog txawv refractive indices thaum dhau los ntawm cov txheej txheem. Lub luag haujlwm ntawm optical diffusion. Txawm li cas los xij, nyob rau hauv txoj kev no, qhov nqus ntawm lub teeb los ntawm diffused hais yuav inevitably muaj nyob, uas ua rau ib tug tsawg siv tus nqi ntawm lub teeb lub zog.
Feem ntau ntxiv cov tshuaj muaj xws li: organic teeb diffusing tus neeg saib xyuas, inorganic lub teeb diffusing tus neeg saib xyuas, sib tov uniformity
LED Diffuser
2. Microstructure LED diffuser
The micro-structured LED diffuser is an array of micro-featured structures on its surface, which makes the light refracted in different directions when passing through, changes the light's travel route, completes the filling and diffused color of the incident light, and achieves a softer and more uniform illumination. Common micro-specialty structures include the following:
AV groove array
BU-zoo li tus convex groove array
C. Pyramid Array
D. Torus array
E. Microlens Array
Microstructure LED diffuser muaj kev xa tawm siab. Los ntawm kev hloov cov duab thiab kev sib txawv ntawm lub microstructure, qhov diffusion pom, qhov chaw thiab lub zog faib ntawm lub teeb pom kev tuaj yeem hloov kho, thiab cov nyhuv ntawm qhov sib xws thiab kev xa tawm ntawm lub teeb diffuser tuaj yeem ua tiav. Yog li ntawd, microstructure LED diffuser phaj tau nyiam cov neeg tshawb fawb zoo.
Yuav ua li cas thov LED diffuser
LED diffuser yog dav siv nyob rau hauv cov kua siv lead ua kua zaub, LED teeb pom kev zoo thiab imaging zaub systems. Nws lub luag haujlwm tseem ceeb yog diffuse qhov teeb meem teeb pom kev zoo kom ua tiav lub teeb pom kev zoo dua thiab zoo dua.
A, LED diffuser yog siv nyob rau hauv cov kua siv lead ua kua zaub system
Siv rau qhov ncaj qha -lit backlight system xaiv rau LCD TVs, LED diffuser phaj muaj kev ua haujlwm zoo xws li kub tsis kam, qhov ruaj khov, lub zog txhua yam, nplaim taws, thiab lwm yam, thiab muaj lub teeb xa hluav taws xob zoo, shading zoo heev thiab durability. Txhawm rau ua kom nws lub teeb diffusion mus rau qhov zoo tshaj plaws, nws yog qhov tsim nyog tshaj plaws rau cov khoom siv hluav taws xob ncaj qha.
B. LED diffuser yog siv rau LED teeb pom kev zoo
Kev xav tau ntawm LED diffuser rau LED teeb pom kev zoo:
1. Qhov zoo tshaj plaws diffusion muaj nuj nqi: siab lub teeb softness
2. High lub teeb kis tau tus mob muaj nuj nqi: txo lub zog noj thiab txhim kho lub illumination ntawm lub teeb
3. Kev cuam tshuam ntawm lub teeb ci: ua raws li qhov sib xws ntawm cov xim kub ntawm lub teeb ci
