RGB Signal Light With IO-Link Interface Reference Design
TIDA-01437
Overview
This reference design implements a five-segment LED smart stack light with 20 LEDs used in factory floor and industrial process automation of greater complexity. An IO-Link interface is implemented for controlling the stack light and reading back status information. The design features low power consumption to be powered through the IO-Link interface.
This signal light reference design demonstrates how the power dissipation of the RGB LED driver can be reduced by 30% and the range of the brightness control can be extended. Automatic brightness control adapts the brightness to ambient light. The reference design uses a simple PWM to modify the output voltage of a switching regulator to implement dynamic headroom control.
Features
- Flexible and easy-to-control RGB LED tower light design
- Different implemented modes: demo, temperature, humidity, stacklight
- Fully controllable through IO-link
- Five segments consisting of 20 RGB LEDs
- Dynamic headroom control of linear RGB LED driver to reduce power consumption by 30%
- Automatic brightness control
Industrial
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
