Lub dimmable coj tsav tsheb ua haujlwm li cas?

Tus neeg tsav tsheb dimmable yog ib qho khoom siv los hloov qhov ci lossis kev siv lub teeb-emitting diodes (LED) teeb pom kev zoo. Nws kho cov hluav taws xob hluav taws xob muab rau cov LEDs, tso cai rau cov neeg siv khoom kho lub teeb ci rau lawv nyiam. Dimmable tsav tsheb feem ntau yog siv los ua kom muaj qhov sib txawv ntawm qhov pom kev sib txawv thiab kev xav hauv tsev, chaw ua haujlwm, thiab lwm yam sab hauv tsev thiabsab nraum zoov teeb pom kev zoodaim ntawv thov.

Dimmable LED tsav tsheb feem ntau siv Pulse Width Modulation (PWM) lossis Analog Dimming. Nov yog ib daim ntawv qhia ceev ceev ntawm txhua txoj kev ua haujlwm li cas:

PWM: Nyob rau hauv cov txheej txheem no, tus tsav tsheb LED hloov ceev ceev ntawm LED tam sim no rau thiab tawm ntawm lub siab zaus. Lub microprocessor lossis digital circuitry tswj kev hloov pauv. Txhawm rau kom ua tau raws li qhov tsim nyog qhov ci ci, lub voj voog ua haujlwm, uas qhia txog qhov feem ntawm lub sijhawm LED tawm mus, hloov pauv. Lub voj voog ua haujlwm siab dua ua rau lub teeb ntau dua, thaum lub voj voog ua haujlwm qis qis dua qhov ci. Lub zaus hloov pauv sai heev uas tib neeg lub qhov muag pom tau lub teeb pom kev tas li txawm hais tias LED tas li tig rau thiab tawm.

Txoj hauv kev no, uas feem ntau ua haujlwm hauv cov tshuab dimming, muab kev tswj xyuas meej txog lub teeb pom kev zoo.

Analog Dimming: Txhawm rau hloov qhov ci, qhov nyiaj tam sim no ntws los ntawm LEDs raug kho. Qhov no yog ua tiav los ntawm kev kho qhov voltage thov rau tus tsav tsheb lossis los ntawm kev tswj cov tam sim no nrog lub potentiometer. Analog dimming ua rau cov nyhuv dumming du tab sis muaj qhov qis qis dua li PWM. Nws nquag nyob rau hauv cov laus dimming systems thiab retrofits qhov twg dimming compatibility yog ib qho teeb meem.

Ob txoj hauv kev tuaj yeem tswj tau los ntawm ntau yam kev cai dimming, suav nrog 0-10V, DALI, DMX, thiab kev xaiv wireless xws li Zigbee lossis Wi-Fi. Cov kev cai no cuam tshuam nrog tus neeg tsav tsheb xa cov teeb liab tswj uas kho qhov kev siv dimming hauv cov lus teb rau cov neeg siv tswv yim.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov tsav tsheb dimmable LED yuav tsum tau sib haum nrog lub dimming system nyob rau hauv kev siv, thiab tsav tsheb thiab dimmer compatibility yuav tsum tau soj ntsuam xyuas kom zoo.
