Yintoni i-LED Dimmer Driver?

Ekubeni ii-LED zifuna ukusebenza ngokuthe ngqo kwangoku kunye ne-low voltage, umqhubi we-LED kufuneka ahlengahlengiswe ukulawula ubungakanani bombane ongena kwi-LED.
Umqhubi we-LED yicandelo lombane elilawula i-voltage kunye ne-current kumandla ombane ukuze ii-LED zisebenze ngokukhuselekileyo nangempumelelo. Umqhubi we-LED utshintsha i-alternating current (AC) unikezelo ukusuka kwi-mains ukuya ngqo ngoku (DC) kuba uninzi lwamandla ombane lusebenza kwiinqununu.
I-LED ingenziwa i-dimable ngokuguqula umqhubi we-LED, ojongene nokulawula inani langoku elingena kwi-LED. Lo mqhubi we-LED owenziwe ngokwezifiso, ngamanye amaxesha ubizwa ngokuba ngumqhubi we-LED dimmer, uguqula ukukhanya kwe-LED.
Kubalulekile ukuqwalasela ngokulula ukusetyenziswa komqhubi we-LED ngelixa uthengela enye. Umqhubi we-LED we-dimmer one-double in-line package (DIP) etshintshela ngaphambili yenza kube lula kubasebenzisi ukuguqula imveliso yangoku, ethi yona iguqule ukukhanya kwe-LED.
Ukuhambelana komqhubi we-LED dimmer kunye ne-Triode ye-Alternating Current (TRIAC) iipleyiti zodonga kunye nokubonelela ngombane yenye into onokuyijonga. Oku kuqinisekisa ukuba unokulawula umbane ohamba ngesantya esiphezulu oqukuqela kwi-LED kwaye i-dimmer yakho iya kusebenza kuyo nayiphi na iprojekthi onayo engqondweni.

Iindlela ezimbini okanye ulungelelwaniso lusetyenziswa ngabaqhubi be-LED dimmer ukulawula umbane okhoyo ongena kwi-LED: i-amplitude modulation kunye ne-pulse width modulation.

Ukunciphisa inani elihamba phambili ngoku elidlulayo kwi-LED yinjongo ye-pulse wide modulation, okanye i-PWM.
Umqhubi ngamaxesha athile ujikela i-current and off and back on again to control the amount of current powering LED, even if the current ingene kwi-LED ihlala ingaguquki. Ngenxa yolu tshintshiselwano lufutshane kakhulu, ukukhanya kuya kuba luzizi kwaye kudanyaza ngokukhawuleza kakhulu ukuba kungabonwa ngumntu.

Ukunciphisa umthamo wombane oya kwi-LED kwaziwa ngokuba yi-amplitude modulation, okanye i-AM. Ukukhanya kokukhanya kubangelwa kukusebenzisa amandla amancinci. Ngendlela efanayo, ukunciphisa iziphumo zangoku kumaqondo okushisa aphantsi kunye nokwandisa ukusebenza kwe-LED. I-Flicker iyapheliswa ngesi sicwangciso.
Nangona kunjalo, hlala ukhumbula ukuba ukusebenzisa le ndlela yokuncipha kuthwala ingozi yokutshintsha umbala we-LED, ngakumbi kumanqanaba asezantsi.

Ukufumana abaqhubi abacimayo be-LED kuya kukuvumela ukuba ufumane okuninzi kwisibane sakho se-LED. Thatha ithuba lenkululeko yokutshintsha amanqanaba okuqaqamba kwee-LED zakho ukonga amandla kwaye ube nesona sibane sikhululekileyo endlwini yakho.
Qhagamshelana nathiNgaba ufuna izibane ze-LED ezine-dimmer / dimmer dirver okanye ezinye izincedisi.
