Web28 de feb. de 2024 · Slicing inside an LED bulb to see the phosphor cap (left) and the LEDs themselves (right). On the bottom of these bulbs, there’s a lump of metal to act as a heat sink. LEDs don’t produce much heat but it is bad for them, so the heat sink is needed to remove it. This also means more efficient LEDs are cheaper to make as a smaller heat … WebThe difference between needing 100% and 80% heat sinking =. 10W / 8W = 25% more. so insignificant in practice. For longest life you want lowest heat sink rise. So say 30C heatsink rise and the less the better. 30C rise for 10W = 3 C/W. Without a fan this is a very substantial heatsink. With a fan this is doable.
