12-ntsis kev koom ua ke PWM RGB LED tsav tsheb
Daim ntawv thov: toj roob hauv pes teeb pom kev zoo
Thaum Lub Kaum Ob Hlis 2018, Texas Instruments qhia txog LP5018, LP5024, LP5030 thiab LP5036 LED series cov tsav tsheb uas suav nrog kev sib xyaw xim ywj pheej, tswj kev ci thiab txuag lub zog. Cov khoom siv no txhawb nqa cov xim du, zoo ib yam, thiab tseem tuaj yeem pab cov khoom lag luam teeb pom kev zoo txo qis kev siv hluav taws xob.
Plaub tus neeg tsav tsheb tuaj yeem muab 29-kHz dimming zaus ntau dua li kev hnov lus ntawm tib neeg pob ntseg, pab tsim qauv tsim cov khoom siv hluav taws xob nqa mus los, tsim kho lub tshuab thiab khoom siv thiab lwm yam ntawv thov uas siv tib neeg-tshuab sib tham, tshem tawm lub pob ntseg dab tsi feem ntau hnov thaum lub teeb suab nrov.
Ib qho ntxiv, piv nrog cov txheej txheem ntsuas ntsuas dav dav (PWM), cov tsim qauv siv 12-ntsis PWM lub tshuab hluav taws xob sib xyaw ua ke hauv plaub tus neeg tsav tsheb no txhawm rau kho cov xim thiab qib ci ntsa iab, ntxiv ntau lub teeb pom kev zoo rau lub teeb pom kev zoo.
Xinyuanhui lub teeb dej hauv qab yog lub chaw tsim khoom tshaj lij ntawm cov dej hauv qab coj lub teeb. Txog kev tsav tsheb thiab xaiv cov khoom tsim khoom, koj tuaj yeem siv peb cov khoom lag luam nrog lub siab.
