Description

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
