Nalalka LED-ka si fiican uma soo bixi doonaan dhawaan

t hadda, heerka tayada nalalka waddooyinka LED ee suuqa waa mid aan sinnayn. Meelo badan, nalalka waddooyinka ee LED si fiican uma soo bixi doonaan dhawaan. Ka dib markii cilmi-baarista eeWaddooyinka Leed warshadeeyayaasha, Sababta asaasiga ah ee dhacdadan ayaa ah in nalka dariiqa LED uu leeyahay waxqabadka kulaylka oo liita. Marka waxqabadka kuleylka kuleylka uu liito, heerkulka gudaha ee iftiinka LED wuxuu noqon doonaa mid aad u sarreeya. Marka heerkulka LED-ku kor u kaco, iska caabinteeda isgoysyada ayaa hoos u dhacda, taasoo keentay hoos u dhac ku yimaadda korantada.

Marka la eego xaaladaha korantada ee isku midka ah, kor u kaca heerkulka gudaha ee iftiinka LED wuxuu kordhin doonaa iftiinka hadda jira. Korodhka hadda wuxuu keenaa in heerkulku uu sare u kaco, taas oo keenta in wareegga xun uu gubo chip LED. Waxaa intaa dheer, heerkulka gudaha ee iftiinka dariiqa LED waa mid aad u sarreeya, kaas oo sidoo kale keena in la kordhiyo iftiinka iftiinka ee chip LED, si ay u horseedi doonto ifafaale dhalaalaya oo aan dhalaalaya mustaqbalka dhow. Haddaba waa maxay sababta ay u liidato kulaylka liidata ee nalka waddada LED?

Marka hore, tayada nalalka waddooyinka ee LED-ka ayaa naftooda iftiiminaya.

Chip-ka LED-ka ee la isticmaalo waxa uu leeyahay kulayl-xumo liidata, heerkulka LED-ga dhintana laguma gudbiyo dusha sare (kulka gudaha iyo qabowga). Xitaa haddii weel kuleyl ah lagu daro, kulaylka gudaha si buuxda looma baabi'in karo, ka dibna iftiinka waddada LED ma aha mid kuleyl ah gudaha.

Marka labaad, kor u kaca heerkulka uu sababay laydhka wadada LED.

Tayada iftiinka dariiqa LED ma fiicna. Marka laydhku shido, laydh-la'aanta laydhka iyo is-beddelka daciifka ah ee tamarta waxay keenaysaa in hadda oo loo marayo chip LED uu kordho, taas oo keeni doonta in heerkulka gudaha uu aad u sarreeyo, taas oo saameyn doonta kulaylka. waxqabadka kala daadinta iftiinka wadada LED.

Qof kastaa wuxuu u baahan yahay inuu fiiro gaar ah u yeesho cimri dhererka nalalka waddooyinka ee LED. Markaad wax iibsaneyso, isku day inaad doorato kuwa soo saarayaasha nalalka LED-ka ee la isku halayn karo, sidoo kale fiiro gaar ah u yeelo dayactirka joogtada ah, si loo hubiyo xasilloonida nalalka waddooyinka.
