Abstract: The LED used in machine vision for recognition and TC7W08F datasheet and other special occasions, this paper presents a control based on high dynamic range ZibBee LED analog dimming device, provides a different from the high-frequency PWM dimming method. Linear power supply on the original design improvements, an increase of variable step-down circuit improves the efficiency of their work and TC7W08F price and achieve a 500: 1, high dynamic range analog dimming. Using both circuit current control CC2430 chip and TC7W08F suppliers and wireless remote control functions, can be combined with the ZigBee wireless gateway for remote dimming control. 1 Introduction The light emitting diode (LED) technology continues to evolve, LED because of its high light efficiency, fast response, wide range of brightness adjustment, is gradually applied to...
