When LED is transforming the light source, part of the electricity would be transferred to heat, and the heat shall be dispersed in the air to keep the LED stable. Overheating temperature of LED Lights would cause accelerated light decay and shorten the lifetime of LED lights.What’s worth mentioning is with the improvement of led high bay chips technology, the transformation efficiency will be improved as well. Less electricity will be consumed to transform into heat, so heat sink can be slimmer. Thus the cost will be reduced which is good for LED promotion. However, this is only the direction of technology development yet, because heat sink is still the technology point we need to explore into.
