Metsotso e meraro ea ho bala ka "high-tech" lebone la LED

I: Li-LED ke eng?
Mohloli o khanyang ka mor'a mabone a khanyang, mabone a fluorescent, ho nts'etsopele ea LED, LED e na le tšebeliso e tlaase ea matla, khanya e phahameng, mercury e se nang chefo e se nang chefo, bophelo bo bolelele, ho qala hang-hang, polasetiki le melemo e meng, e nkile sebaka sa mohloli oa leseli oa setso. sehloohong sena ha e etse ho hongata haholo mohloling oa leseli oa setso ho hlahloba.

Ho thoeng ke LED ke Light Emitting diode khutsufatso, ke hore, khanya-emitting diode, ke semiconductor khanya-emitting thepa, ha lipheletsong tse peli hammoho le pele gagamalo, semiconductor bajari ka motsoako bakoang ke photon tlhahiso le hlahisa leseli.LED e ka hlahisa ka ho toba bofubelu, bo mosehla, boputsoa, ​​​​botala, boputsoa, ​​​​orange, pherese, leseli le lesoeu.

II: Sebopeho sa lifaha tse khanyang tsa LED
1, mohloli o khanyang oa LED ka bracket, chip, glue, phosphor, sebopeho sa terata
2, LED bracket hangata e entsoe ka koporo (ho boetse ho na le tšepe, aluminium le ceramic, joalo-joalo), hobane conductivity ea koporo e ntle haholo, e tla ba le lead ka hare, ho hokahanya li-electrode ka har'a lifaha tse etelletsoeng pele.
3, terata ea mohloli o phahameng oa pheletso e sebelisoa 0.999 terata e hloekileng ea khauta, bophara bo fetang: 0.8mil, 1.0mil.ba bang ba lelekisa bahlahisi theko e tlaase le koporo motsoako doped terata ho etsa.
4, phosphor e bapala karolo ea ho lokisa mocheso oa 'mala oa mohloli oa leseli.
5, li-chips tse tloaelehileng tse phahameng ke: United States CREE (Core), Bridgelux (Bridgelux);Japane Nichia (Nichia), Jeremane Osram Osram;Taiwan: Epistar.

III: Mehloli e tloaelehileng ea leseli la LED
'Maraka o atisa ho ajoa mehlala ea LED ke 2835, 5050, 5730, 5630, 3030, 4040, 7030 le COB e kopantsoeng le lifaha tse matla, ho khetholla mohlala oa mohloli o khanyang o bitsoa ka bolelele le bophara ba SMD SMD, mohlala. , palo e latelang ea 2835 SMD, ke hore, bophara ba 2.8 bolelele ba 3.5, mehloli e joalo ea leseli e atisa ho sebelisoa ka mabone a LED, mabone a tlaase, mabone, mabone a siling, lihlopha tse khanyang Mehloli ena ea leseli e sebelisoa hangata ka mabone a LED, mabone a tlaase, mabone, mabone a siling, mabone a hlobolisa, li-tubes joalo-joalo.Matla a mang le a mang a fetang 0.1W-1W.
Lifaha tsa matla a phahameng li sebelisoa hangata bakeng sa 1W, 2W, 3W e ​​'ngoe le e' ngoe, e sebelisoang hangata ho mabone le mabone a kantle.
Mehloli e kopantsoeng ea COB e atisa ho sebelisoa ka mabone a matla a phahameng a kang mabone, mabone a pina le mabone a likhohola, e 'ngoe le e' ngoe e na le matla a 5-50W.
