Chida cha LED ndi chipangizo cha semiconductor kuti chizimitsa utoto wopepuka. Ndi mosiyana kwambiri ndi magwero achikhalidwe, monga nyali zam'madzi, nyali zofunda, nyali zoyatsira fluorescent ndi nyali zonyansa kwambiri. Kodi amakonzekera bwanji?
Chithunzi: Verbatim.
Palibe ulusi wamafuta ndi mpweya mu LED, ilibe galasi lofooka komanso magawo omwe angakhale osalimbikitsa. Kuwala kwa kuwalako kumachitika chifukwa cha kubwezeretsa ma elekitoni ndi mabowo pansi pazomwe zimachitika mu semictroctron mu Sevonductor, chifukwa cha mapulogalamu osakhalitsa amatulutsidwa . Ndi chiyani?
Kumasankhidwa mophweka izi kumatha kulingalira za semiconductor pamene ma halves awiri olekanitsidwa ndi intergyer yochepa kwambiri. Mu theka limodzi pali zochulukirapo zolipiritsa (ma electrons). Kudera lina, kuchuluka kwa tinthu tating'onoting'ono (mabowo). Mothandizidwa ndi tinthu tating'onoting'ono timapeza mwayi woti ubweretse dielectric wosanjikiza. Msonkhano wa tinthu yabwino komanso yolakwika yomwe imayendetsedwa ndi kutulutsa kwa mphamvu mu mawonekedwe a zithunzi zomwe zimafotokozedwa mokhazikika. Itha kukhala zithunzi zonse ndi mawonekedwe owoneka bwino (ofiira, obiriwira, abuluu, abuluu) gawo losaoneka la mawonekedwe, mwachitsanzo, ultraviolet kapena infrared.
Poyamba (mu makumi asanu ndi limodzi), matikiti adawonekera ndi kuwala kofiyira, ndiye kuti ndi wobiriwira, koma mu 1993 kokha mu 1993 mawebusayiti owoneka bwino kwambiri. Kuyambira nthawi imeneyo, chitukuko cha zida zowunikira malinga ndi ma LED, omwe amatha kupatsa mawonekedwe aliwonse owala, kuphatikizapo zoyera.
Chithunzi: mafili.
Mawebusayiti onse owunikira ali ndi kapangidwe koyambirira. Amaphatikizapo chip seanduct chip (kapena galasi), gawo lapansi lomwe limayikidwa, kulumikizana kwa kulumikizana kwamagetsi, kulumikizana kolumikiza kulumikizana ndi kristalo, kumira, nyumba ndi nyumba.

Chifukwa chiyani ma ads abuluu anali ofunika kwambiri? Chowonadi ndi chakuti ndi thandizo lawo lomwe mungapeze mitundu ya mithunzi ina. Pachifukwa ichi, Mzere wotsogozedwayo umakutidwa ndi luminophore, wonyezimira ndi kuunika kwa kamvekedwe ka kamveke. Maukadaulo a Luminofor popanga kuwala koyera kumaphatikizapo kugwiritsa ntchito ma radiation radiation imodzi yapamwamba kwambiri, mtundu wa buluu kapena ultraviolet, kuphatikiza ndi zokutira wachikasu wa luminoophope. Photons wopangidwa ndi kutsogozedwa, kapena kudutsa mu luminopbore wosanjikiza wosasinthika, amasinthidwa kukhala a zithunzi za kuwala kwachikasu. Kuphatikiza kwa zithunzi za buluu ndi chikasu mtundu kumapanga kuwala koyera.
Njira yosakanikirana ndi matope atatu a mthunzi wosiyana (wofiyira, wobiriwira komanso wabuluu) amatchedwa njira ya RGB. Zimapangitsa kuti zitheke kupanga kuwala koyera kwa mthunzi wolondola wokhala ndi kuthekera kutsindika mitundu. Komabe, kuti apange RGB yoyera, zida zovuta kwambiri zimafunikira, chifukwa madandaulo atatu akuyenera kugwiritsidwa ntchito mwanjira ina. Pankhaniyi, mawonekedwe ake osakhala okhanu amagawika mitundu ya pastel, yomwe ndi zotsatira zazikulu za choyera choyera choyera chomwe chimaperekedwa ndi njira yoyera yopezeredwa ndi RGB, motero, njirayi siyigwiritsidwa ntchito mu nyali (koma imagwiritsidwa ntchito pone riboni wopepuka).

Zigawo zikuluzikulu za chida cha LED zimaphatikizapo:
- Kwenikweni, ma LED ndi maderalo omwewo, muwonetse ntchito yawo.
- Magetsi opezeka ndi microproctor kuwongolera, magetsi otembenuka ndikuwongolera madera.
- Zida zochotsa kutentha (mabowo oyenda bwino ndi ma radiators).
- Magalasi ndi zida zomangira kulowera, kusakaniza ndikubalalitsa kuwala.
