LED ke mofuta oa semiconductor e hlahisang leseli ha o e fa matla a itseng.Mokhoa oa eona oa tlhahiso ea leseli o batla o le lebone la fluorescent le lebone la ho ntša khase.LED ha e na filament, 'me leseli la eona ha le hlahisoe ke ho futhumatsa ha filament, ke hore, ha e hlahise leseli ka ho lumella hore hona joale ho phalle ho li-terminals tse peli.LED e ntša maqhubu a motlakase (maqhubu a phahameng haholo a ho sisinyeha), ha maqhubu ana a fihla ka holimo ho 380nm le ka tlaase ho 780nm, bolelele ba maqhubu bohareng ke leseli le bonahalang, leseli le bonahalang le ka bonoang ke mahlo a motho.

Li-diode tse ntšang khanya le tsona li ka aroloa ka li-monochrome light-emitting diode tse tloaelehileng, li-diode tse hlahisang khanya e phahameng haholo, li-ultra-highlightlight light-emitting diode, tse fetolang mebala tse ntšang khanya, li-flashing light-emitting diode, tse laoloang ke voltage. li-diode tse ntšang khanya, li-infrared light-emitting diode le li-radiode tse thibelang mabone a khanyang.

kopo:

1. Letšoao la matla a AC

Hafeela potoloho e ntse e hokahane le mohala oa motlakase oa 220V / 50Hz AC, LED e tla khantša, e bontšang hore matla a teng.Boleng ba ho hanyetsa ba mohanyetsi oa hona joale oa moeli oa R ke 220V/IF.

2. AC switjha pontshi leseli

Sebelisa LED e le potoloho bakeng sa mabone a li-switch switch mabone a incandescent.Ha sesebelisoa se khaotsoe 'me lebone la lebone le tima, hona joale ho etsa loop ka R, LED le lebone la lebone la EL, 'me lebone la LED le bonesa, e leng ntho e loketseng hore batho ba fumane sesebelisoa lefifing.Ka nako ena, hona joale ka har'a lupu e nyenyane haholo, 'me lebone la lebone le ke ke la khantša.Ha switjha e buletsoe, tleloubu ea buloa 'me LED ea tima.

3. Leseli la sokete ea matla a AC

Potoloho e sebelisang mebala e 'meli (cathode e tloaelehileng) LED e le lebone la pontšo bakeng sa phallo ea AC.Matla a motlakase ho sokete a laoloa ke switjha S. Ha LED e khubelu e le teng, sokete ha e na matla;ha LED e tala e bulehile, sokete e na le matla.
