usebenza njani umqhubi we-LED ocimayo?

Umqhubi ocimayo sisixhobo esisetyenziselwa ukuguqula ukuqaqamba okanye ubunzulu bezixhobo zokukhanyisa ezikhanyayo (LED). Ilungelelanisa amandla ombane anikezelwe kwii-LED, okuvumela abathengi ukuba benze ukukhanya okukhanyayo ngokuthanda kwabo. Abaqhubi abacimayo bahlala besetyenziselwa ukwenza ukukhanya okungafaniyo kunye neemoods kumakhaya, iiofisi, kunye nezinye izinto zangaphakathi kunye.ukukhanya kwangaphandleizicelo.

Abaqhubi be-LED abacimayo basebenzisa i-Pulse Width Modulation (PWM) okanye i-Analog Dimming. Nalu uluhlu olukhawulezayo lwendlela indlela nganye esebenza ngayo:

I-PWM: Kobu buchule, umqhubi we-LED utshintsha ngokukhawuleza i-LED yangoku kunye nokucima kwi-frequency ephezulu kakhulu. I-microprocessor okanye i-digital circuitry ilawula ukutshintsha. Ukufumana inqanaba lokukhanya elifanelekileyo, umjikelo womsebenzi, obonisa ubungakanani bexesha apho i-LED ikhanya xa ithelekiswa nokucima, iyatshintshwa. Umjikelo womsebenzi ophezulu uvelisa ukukhanya okungakumbi, ngelixa umjikelo womsebenzi ophantsi unciphisa ukukhanya. I-frequency switching frequency ikhawuleza kangangokuba iliso lomntu libona ukuphuma kokukhanya okuqhubekayo nangona i-LED ihlala ivula kwaye icima.

Le ndlela, edla ngokusetyenziswa kwiinkqubo ze-digital dimming, inika ulawulo oluchanekileyo kwimveliso yokukhanya.

I-Analog Dimming: Ukutshintsha ukukhanya, inani langoku elihambayo kwii-LEDs liyalungiswa. Oku kufezwa ngokulungelelanisa i-voltage esetyenziswe kumqhubi okanye ngokulawula okwangoku nge-potentiometer. Ubumnyama be-analog buvelisa isiphumo sobumnyama esigudileyo kodwa sinoluhlu olusezantsi lobumnyama kune-PWM. Ixhaphakile kwiisistim ezindala zokufiphaza kunye ne-retrofits apho ukuhambelana kobumnyama kungumba.

Zombini iindlela zinokulawulwa ngeendlela ezahlukeneyo zeprothokholi, kuquka i-0-10V, i-DALI, i-DMX, kunye neenketho ezingenazintambo ezifana ne-Zigbee okanye i-Wi-Fi. Ezi prothokholi zijongana nomqhubi ukuthumela isiginali yolawulo ehlengahlengisa ubunzulu bobumnyama ekuphenduleni kwigalelo lomsebenzisi.

Kubalulekile ukukhumbula ukuba abaqhubi be-LED abacimayo kufuneka bahambelane nenkqubo yobumnyama esetyenziswayo, kwaye ukuhambelana komqhubi kunye ne-dimmer kufuneka kuqinisekiswe ukusebenza ngokufanelekileyo.
