Tus tsav tsheb dimmable ua haujlwm li cas?

Tus tsav tsheb dimmable yog ib lub cuab yeej siv los hloov qhov ci lossis qhov muaj zog ntawm cov teeb pom kev zoo (LED). Nws kho lub zog hluav taws xob uas muab rau cov LEDs, tso cai rau cov neeg siv khoom kho qhov ci ntawm lub teeb raws li lawv nyiam. Cov tsav tsheb dimmable feem ntau siv los tsim cov teeb pom kev zoo sib txawv thiab cov cwj pwm hauv tsev, chaw ua haujlwm, thiab lwm yam sab hauv tsev thiabteeb pom kev zoo sab nraum zoovcov ntawv thov.

Cov tsav tsheb LED uas dimmable feem ntau siv Pulse Width Modulation (PWM) lossis Analog Dimming. Nov yog kev piav qhia luv luv txog txhua txoj kev ua haujlwm li cas:

PWM: Hauv cov txheej txheem no, tus tsav tsheb LED hloov pauv sai sai ntawm LED tam sim no rau thiab tawm ntawm qhov zaus siab heev. Lub microprocessor lossis digital circuitry tswj qhov kev hloov pauv. Txhawm rau kom tau txais qib ci ntsa iab tsim nyog, lub voj voog ua haujlwm, uas qhia txog qhov sib piv ntawm lub sijhawm uas LED qhib thiab kaw, raug hloov pauv. Lub voj voog ua haujlwm siab dua tsim ntau lub teeb, thaum lub voj voog ua haujlwm qis dua txo qhov ci ntsa iab. Lub zaus hloov pauv yog sai heev uas lub qhov muag tib neeg pom qhov tso zis teeb pom kev tas mus li txawm tias LED tig thiab tawm tas li.

Txoj hauv kev no, uas feem ntau siv rau hauv cov tshuab digital dimming, muab kev tswj hwm qhov tseeb ntawm lub teeb tso zis.

Kev Tiv Thaiv Teeb Meem Analog: Txhawm rau hloov qhov ci ntsa iab, qhov ntau ntawm cov hluav taws xob ntws los ntawm cov LEDs raug kho. Qhov no ua tiav los ntawm kev kho qhov voltage siv rau tus tsav tsheb lossis los ntawm kev tswj cov hluav taws xob nrog lub potentiometer. Kev tiv thaiv teeb meem analog tsim cov nyhuv dimming du tab sis muaj qhov dimming qis dua li PWM. Nws feem ntau nyob rau hauv cov kab ke dimming qub thiab cov khoom siv kho dua tshiab uas qhov kev sib raug zoo ntawm kev tiv thaiv teeb meem yog qhov teeb meem.

Ob txoj kev no tuaj yeem tswj tau los ntawm ntau yam kev tswj hwm dimming, suav nrog 0-10V, DALI, DMX, thiab cov kev xaiv wireless xws li Zigbee lossis Wi-Fi. Cov kev tswj hwm no sib txuas nrog tus tsav tsheb kom xa cov teeb liab tswj uas kho qhov muaj zog dimming raws li cov lus qhia ntawm tus neeg siv.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov tsav tsheb LED dimmable yuav tsum sib xws nrog lub kaw lus dimming uas siv, thiab kev sib xws ntawm tus tsav tsheb thiab dimmer yuav tsum tau txheeb xyuas kom ua haujlwm tau zoo.
