Icho chinhu chakajairika kuti mwenje ye LED inosviba sezvaanoshandiswa. Pane zvikonzero zvitatu zvinoita kuti mwenje we LED udzike:.
Drive wakuvadzwa
Machipisi e LED anodiwa kuti ashande pane yakaderera DC voltage (pazasi 20V), asi yedu yakajairika mains simba ikakwira AC voltage (220V AC). Kushandura simba rema mains mumagetsi anodiwa kune machipisi e LED, mudziyo unonzi "LED inogara iripo yekutyaira magetsi" inodiwa.
Mune dzidziso, sekureba ma paramita emutyairi achienderana neiyo LED bhodhi, inogona kuramba ichigoneswa uye kushandiswa zvakajairwa. Chimiro chemukati chemutyairi chakanyanya kuoma, uye chero mudziyo (senge capacitor, rectifier, etc.) iyo malfunctions inogona kukonzera shanduko mukubuda kwemagetsi, izvo zvinogona kuita kuti chigadziriso chemwenje chidzike.
Kukuvadzwa kwemutyairi ndiyo yakajairika mhando yekusashanda mumagetsi emwenje e LED, ayo anogona kazhinji kugadziriswa nekutsiva mutyairi.
LED yakatsva
LED pachayo inoumbwa nemusanganiswa wemarangi akareruka, uye kana imwe kana chikamu chawo dzikasavheneka, ichaita kuti mwenje wese udzime. Marambi emarambi anowanzo kubatanidzwa munhevedzano uyezve achifambirana - saka kana bhiza rimwe rikatsva, rinogona kukonzera bhechi remabheti kuti risavheneke.
Pane mavara matema ari pachena pamusoro pebhedhi remwenje wakatsva. Tsvaga uye ubatanidze waya kumusana wayo kune pfupi-circuit iyo; Neimwe nzira, kutsiva girobhu neritsva kunogona kugadzirisa dambudziko.
Dzimwe nguva, imwe LED inopisa kunze, inogona kunge iri masanga. Kana iyo inowanzopisa kunze, saka nyaya dzekutyaira dzinofanirwa kutariswa - imwe ratidziro yekutadza kwekutyaira ndeyekutsva kwe LED machipisi.
Kuora kwechiedza che LED
Izvo zvinonzi kuora kwechiedza kunoreva kuderera kupenya kwemuviri unopenya, uyo unonyanya kutaurwa mune incandescent uye fluorescent mwenje.
Magetsi e LED zvakare haakwanise kudzivirira kuora kwechiedza, asi iwo mwero wekuora kwemwenje unononoka, uye kazhinji zvakaoma kuona shanduko neziso rakashama. Asi hazvigone kutongerwa kuti ma LED emhando yakaderera, kana mabhodhi emhando yakaderera, kana zvinhu zvine chinangwa senge kushata kwekupisa kupisa zvinogona kuita kuti chiyero chekuora kwe LED chiwedzere.
