I'm wondering if there are any thermal management issues to anticipate, especially if you wanna build a safe commercial product. It's quite known that the limit to LED brightness rapidly becomes heat management, either of the power supply or the LED itself.
- orbital-decay 5y agoIn LED lighting space, insufficient heat dissipation is commonly used for planned obsolescence. LED lifetime directly depends on temperature, and most light sources are way too powerful for their heat dissipation capabilities.
