RGBW Strobe Tester

For TwinleWork’s new line of RGBW LED strobes, we needed a new testing assembly. This unit automatically tests each of the LEDs’ colors as well as the strobe fixture’s temperature sensing circuitry.

The unit is based off of several Meanwell LED drivers, a variety of analog sensing circuitry, a light sensor, and an Arduino Pro Mini.

The pogo sticks stick out of a 3D printed assembly for lining up the strobe PCBAs, which also protects the user from 1000s of lumens of light output.

The fixture can test PCBs in a matter of seconds. Terminal blocks (which will be connected to test clips) will also allow for completed strobes to be connected to the tester and tested once assembled.

A work in progress datasheet for the RGBW strobe can be found here, for reference only.
