Hello,
How do you cool the LEDs and the switch mode LED driver which are present inside a LED beacon like this.?
https://www.lightbar-shop.co.uk/Britax-LED-Beacon-80.html
The power dissipation is 10W, and there is no internal fan, and no ventilation holes whatsoever.
The diffusor is perspex, so unfortuately is thermally insulating.
Also, this product is used out in the sunlight, so suns rays will get trapped inside and make it super hot.
Even if you put a big aluminium heatsink in there, where is it going to conduct the heat away to?
And do you agree that putting the LED Driver PCB on the same heatsink that the LEDs are on is bad practice, since the LED driver will simply run too hot?
