Icho chinhu chakajairika kuti mwenje ye LED inodzima zvakanyanya kana ichishandiswa.Kupfupisa, pane zvikonzero zvitatu nei mwenje we LED uchigona kudzimwa.

Drive kukundikana.

LED rambi bead zvinodiwa muDC low voltage (pazasi 20V) inoshanda, asi yedu yakajairika mains ndeye AC yakakwira voltage (AC 220V).Magetsi anodiwa kushandura magetsi emagetsi kuita bhero remwenje anoda mudziyo unonzi "LED constant current drive power supply".

Tichingotaura, sekureba maparamita emutyairi uye bead board match, anogona kuramba achiita simba, kushandiswa kwakajairika.Mukati memutyairi wakanyanya kuoma.Iko kukundikana kwechero mudziyo (senge capacitor, rectifier, nezvimwewo) zvinogona kukonzera shanduko yekubuda kwemagetsi, izvo zvinokonzeresa kudzima kwemwenje.

Kupisa kwe LED.

LED pachayo inoumbwa nekubatanidzwa kwemarambi emarambi, kana imwe kana chikamu chechiedza chisina kujeka, chinosungirwa kuita kuti mwenje wese usvibe.Marambi emarambi anowanzo kubatanidzwa munhevedzano uyezve mukuenderana - saka mwenje wemwenje wakatsva, zvinogoneka kuita kuti huwandu hwemarambi huve husina kujeka.

Pane mavara matema ari pachena pamusoro pebhedhi remwenje wakatsva.Itsvage woibatanidza newaya kumusana kuti iite short-circuit pairi.Kana kutsiva bhero remwenje idzva, rinogona kugadzirisa dambudziko.

LED dzimwe nguva yaipisa imwe, zvichida netsaona.Kana iwe uchipisa kazhinji, unofanirwa kufunga nezvematambudziko emutyairi - kumwe kuratidzwa kwekutadza kwemutyairi ndiko kupisa kwebheti.

LED inopera.

Kuora kwechiedza ndipo apo kupenya kwechiedza kunowedzera uye kushoma - mamiriro anonyanya kutaurwa mumarambi e-incandescent uye fluorescent.

Mwenje ye LED haigoni kudzivirira kuora kwechiedza, asi kukurumidza kwayo kuora kwechiedza kunononoka, kazhinji neziso rakashama rakaoma kuona shanduko.Asi hazvibatanidzi yakaderera LED, kana yakaderera chiedza bead bhodhi, kana nokuda kwakashata kupisa dissipation uye zvimwe chinangwa zvinhu, zvichikonzera LED chiedza kuderera kumhanya inova nokukurumidza.
