While I am working on the PCB of my Smart Headlight circuit design, I got the sparkling idea about thermal protection for Würth Elektronik's LEDs. Würth Elektronik's LEDs has thermal pad contact on their high bright LEDs to control heat dissipation, I have seen some post from other Road testers too, but, my idea is to use single mid sized heatsink for all the LEDs. More or less 76 LEDs in total. I can't provide numerous heatsinks for that much volume of LEDs and in small size of circuit board...
So here is my approach...
It's not finished or the actual full circuit design, It's just the experiment deign to show you guys how I am going to use single heatsink for my LEDs. The curved or swirled traces will be on the centre of my circuit board, the outer most edges of the swirl trace will be connected to thermal pad of LEDs as I shown in the example PCB design. All the LED thermal pad traces will be well layered and connected to swirl traces, the centre most of swirl trace will be connected to single heatsink, either on the trace layer side of the circuit board or the backside. In this way I can reduce heat of numerous LEDs and connected to single heatsink, as well save space in circuit board...
So I am asking Würth Elektronik and other experts here to comment on this approach... As I am doing this as experiment with my little idea. Awaiting for your inputs
FYI: This is not actual PCB design with resistors,LEDS, etc, etc, it's just an example to show my idea, hope you people get my point here...
