This LED Driver with ZAURA Control reference design integrates Zilog’s ZAURA RF 868 MHz Wireless Module onto an LED Driver Base Power Board to create an LED Driver Demonstration Board designed to showcase the features and performance of an inductor-based light-emitting diode (LED) driver with active power factor correction (PFC) and a microcontroller (MCU). This reference design can be used as a basis for developing systems that can control fluorescent lighting installations.
On its own, without the ZAURA RF Wireless Module attached, the LED Driver Base Power Board functions as a demonstration board, providing current to power an LED string. However, the LED Driver Base Power Board cannot control LED brightness because the source of the PWM pulses required to perform this operation is generated by the Z8F2480 MCU on the RF Module.
In combination, the LED Driver Base Power Board with the Module attached, all controlled by a hand-held remote control device, enable RF communication to turn LEDs on and off, and to adjust the brightness of these LEDs within a 10%–100% range. To prevent damage to the LEDs in the event of overheating, the MCU can, for example, monitor the temperature of an LED board, decreasing the brightness of the LEDs if the temperature of the board exceeds a preset threshold.
For purposes of demonstrating RF control, a hand-held ZAURA RF Remote Control Device is also included with this reference design.
The LED Driver with ZAURA Control reference design features the following elements:
- LED Driver Base Power Board
- ZAURA RF 868 MHz Wireless Module
- Controls LED brightness from a remote source
- 90 VAC to 130 VAC input
- A thermal protection mechanism can easily be added to decrease the LED brightness as temperature exceeds user defined threshold levels
