Xariijimaha LED aad iyo aad ayey caan u yihiin waxayna door fiican u yihiin ganacsiga, deegaanka, iyo iftiinka warshadaha. Waa kuwo hufan, fududahay in la rakibo waxayna u baahan yihiin dayactir aad u yar. Waxaad u habeyn kartaa xargaha LED-yada qaabab iyo cabbirro kala duwan, si aad u isticmaasho si aad u iftiimiso meel kasta.
Qaybaha ugu muhiimsan ee xariijimaha LED-yada waa SMD LEDs, FPCB Xarigga LED-ka waxaa lagu soo saaray iyadoo la adeegsanayo habka loo yaqaan 'Surface Mount Technology' (SMT) Habka Golaha si loogu dhejiyo LED-yada, iska caabiyeyaasha iyo qaybaha kale ee FPCB.
Diode iftiin leh (LED) waa il iftiin semiconductor ah oo iftiimiya iftiinka marka uu hadda dhex socdo. Electron-yada ku jira semiconductor-ku waxay dib ula midoobaan godadka elektarooniga ah, iyagoo siidaaya tamarta qaab sawiro ah. Midabka iftiinka (oo u dhiganta tamarta photon-yada) waxaa lagu go'aamiyaa tamarta looga baahan yahay elektarooniga si ay uga gudbaan farqiga band ee semiconductor. Iftiinka cad waxaa lagu helaa iyadoo la isticmaalo semiconductors badan ama lakabka fosfoorka iftiinka soo baxaya ee qalabka semiconductor.
Inta badan awooda ay isticmaalaan xariijinta LED-yada waxay ka timaadaa tamarta ay isticmaalaan LED-yada SMD.
LED-yadu waxay isticmaalaan koronto yar oo si gaar ah uma kululaan. Waxaa si buuxda u iftiimiyay dhaqdhaqaaqa elektarooniga ah ee walxaha semiconductor, waxayna leeyihiin cimri dherer ilaa inta transistor-ka caadiga ah uu ka badan yahay 50,000 saacadood. LED-yadu waxay leeyihiin faa'iidooyin dhowr ah marka loo eego nalalka caadiga ah, laakiin faa'iidadooda ugu weyn waa waxtarka. Nalalka shidan, habka wax soo saarka iftiinka wuxuu ku lug leeyahay soo saarista kulayl badan (filaha waa in la kululeeyaa si loo iftiimiyo). Haddii aanad u isticmaalin nalka shidan sidii kuleyliyaha, tamartani gabi ahaanba waa ay luminaysaa, maadaama qayb badan oo ka mid ah korontada la heli karo aan loo isticmaalin in ay soo saarto iftiin muuqda. Marka la eego, LED-yadu waxay soo saaraan kuleyl aad u yar. Boqolkiiba sare ee tamarta korantada ayaa si toos ah loo isticmaalaa si loo soo saaro iftiinka, taas oo si weyn u yaraynaysa baahida korontada.
Nalalka LED-yadu waxay soo saaraan lumen ka badan (ama cadadka iftiinka muuqda) halkii watt marka loo eego nalalka caadiga ah ee shidan. Diodeyaasha iftiimiya waxay leeyihiin hufnaan iftiin sare leh (wax ku oolnimada ay korontadu u beddesho iftiin muuqda) marka loo eego nalalka ifaya. Laydhka 60-watt wuxuu soo saari karaa 750-900 lumen, laakiin waxaad ka heli kartaa isla wax soo saarka nalka LED-ka oo isticmaala 6-8 watts oo keliya.
Sideen u xisaabiyaa isticmaalka tamarta laydhka LED?
Kahor intaadan xisaabin isticmaalka laydhka laydhka, waxaad u baahan tahay inaad ogaatid awooda mitirkii ee fiilada LED-ka iyo inta mitir ee fiilada LED-ka ee jira.
Xarigga LED-yada caadiga ah ayaa lagu heli karaa 2.4W/m (0.73W/cag), 4.8W/m (1.46W/cag), 7.2W/m (2.19W/cag), 9.6W/m (2.93W/cag), 14.4W/m (4.39W/cag), 19.2W/m (5.85W/cag), 24W/m (7.32W/cag) iwm.
Tusaale ahaan, haddii uu jiro xariijin 5m LED ah oo awooddeedu tahay 14.4W/m (1.46W/cag) oo ay shaqeyso 12 saacadood maalintii, 365 maalmood sannadkii, imisa koronto ayaa la isticmaalaa sannadkii?
Xisaabinta waa 14.4*5*12*365=315.360 KW.h
Ugu Dambeyn
Xariijimaha LED-ku aad bay u hufan yihiin waxayna isticmaalaan koronto ka yar kuwa shidan, halogen, iyo nalalka fluorescent.
LEDYi waxay soo saartaa tayo sare leh Xarigga LED-yada iyo dabacsanaanta neon-ka LED. Dhammaan alaabooyinkayagu waxay maraan shaybaarro teknoolojiyad sare ah si loo hubiyo tayada ugu sarreysa. Ka sokow, waxaan ku siin fursado la beddeli karo on our strips LED iyo dabacsanaan neon. Marka, xariijinta LED-ka qaaliga ah iyo dabacsanaanta neon-ka LED, la xiriir LEDYi DHAQSO BADAN!
