I am on design state of a product using 6 power LEDs (1W). Unfortunately, the LEDs at 100% of luminocity produse high temperature level. There is no problem for us to drive them at 80%, but not less.
The Led strip pcb will be double sided, using the bottom side just for heat transfering.
kindly advice, what is prefered:
1. The bottom pcb layer as a heatsink to be cover by a mask layer or
2. to be free to be soldered via the wave process
Please tell me your suggestions based on your experience on issues like this.
Any other idea is acceptable.
Thanks for your time,
