Waa maxay Farqiga u dhexeeya Awood-sare ee LED-ka iyo Awoodda Yar?

Awoodda keli ah ee laydhka sare ee LED-ku wuu sarreeyaa, dhalaalku wuu sii ifayaa, qiimuhuna wuu sarreeyaa. Hadda la qiimeeyay ee nalalka yar yar ee LED waa 20mA, hadda la qiimeeyayna waxa loo tirin karaa awood sare oo hadda la qiimeeyay ka sarraysa 20mA. Nambarka korantada guud waa: 0.25W, 0.5W, 1W, 3W, 5W, 8W, 10W, iwm. Unugga iftiinka ugu weyn waa LM (lumen), unugga dhalaalka ee awoodda yarna guud ahaan waa MCD. Labadan cutub lama beddeli karo. Waqtigan xaadirka ah, sida cagaar soo baxaya, ilaalinta deegaanka, tamarta-badbaadinta isha iftiinka ayaa si weyn loogu isticmaalaa nalalka baabuurta, tooshashka, nalalka iyo meelo kale. Sababta nalalka LED-ka ee awoodda sare leh loogu yeero tan waxaa badanaa loogu talagalay nalalka LED-yada yar yar. Waxaa jira saddex nooc oo heerarka kala soocidda: kan ugu horreeya waa in loo qaybiyaa 0.5W, 1W, 3W, 5W, 10W. .100W way ka duwan tahay, marka loo eego wadarta awoodda wax-soo-saarka ka dib baakooyinka. Nooca labaad waxaa loo qaybin karaa: baakadaha resin epoxy-sized weyn, ku dayashada baakadaha resin epoxy mermaid, baakadaha aluminium, aluminium, aluminium, iyo aluminium. Nooca saddexaad ee substrate (MPCB) koofiyadaha, Si baakadaha, baakad-nooca SMD, xirmo isku dhafan ee MCPCB, iwm. Nooca saddexaad waxaa loo qaybin karaa alaabada tamarta gabowga ee iftiinka hoose iyo kuwa aan iftiinka gabow-hoosayn iyadoo loo eegayo heerka da'da iftiinka. Dabcan, sababtoo ah waxaa jira meelo badan oo ka mid ah iftiinka sare ee LED-ka laftiisa, waxaa jiri doona heerar kala duwanaansho oo kala duwan iyadoo loo eegayo cabbirro kala duwan. Nalalka LED-ka ee awoodda sare leh ayaa weli iska leh mid ka mid ah alaabada baakadaha LED-ka, taas oo ah qaybta ugu muhiimsan ee nalka semiconductor ee dhinaca nalka caadiga ah. Markaad isticmaalayso nalalka LED-ka ee awoodda sare leh, waa inaad fahantaa qaybinta iftiinka qaybinta iftiinka, qaybinta heerkulka midabka, caabbinta kulaylka iyo samaynta midabka si aad u maareyso khariidadda qaybinta iftiinka ee heerka sare ee iftiinka LED-ka. Waa lagama maarmaan in si sax ah loo isticmaalo iftiinka LED-ka ee awoodda sare leh. Wax-soo-saarayaashu waa inay macaamiisha siiyaan tilmaameyaal kala duwan oo ah aaladaha LED-ka haddii qaybinta heerkulka midabka ee nalalka LED-ka ee awoodda sare si siman loo qaybiyo, taas oo si toos ah u saameyn doonta saameynta iftiinka; iyo heerkulka midabka iyo tusaha samaynta midabku waa isku xidhan yihiin, isbeddelka heerkulka midabkuna wuxuu keeni doonaa isbeddel ku yimaada tusmada samaynta midabka. Iska caabbinta kulaylka ee iftiinka tamarta sare ee LED wuxuu si toos ah u saameeyaa kulaylka qalabka LED. Iska caabbinta kulaylka hooseeya, way ka sii fiican tahay kala-baxa kulaylka; caabbinta kulaylku waa mid liidata, si heerkulka qalabku kor u kaco, taas oo saameyn doonta mowjadda dhererka iftiinka. Marka loo eego waayo-aragnimada, heerkulku hal mar ayuu kor u kacaa, dhererka hirarka iftiinka waa in uu ku wareego 0.2 0.3nm, taas oo si toos ah u saameyn doonta tayada iftiinka ee qalabka. Heerkulka xad-dhaafka ah ayaa sidoo kale si toos ah u saameeya nolosha adeegga ee heerka sare ee tamarta LED-nalalka kaydinta. Midabaynta waa tilmaame muhiim ah oo nalka cad ee LED. Midabka iftiinka cad ee LED ee nalka waa inuu ka sarreeyaa 80 ama ka badan.
