LEDs are more efficient than light bulbs, transforming roughly 30% of supplied electric power into light, yet 70% of this energy is cast off as heat. This lost heat needs to be dissipated because high temperatures affect the semiconductor’s properties and, ultimately, its lifespan. The following article takes a closer look at the thermal aspects of LEDs, comparing a range of different heat conducting materials.
