Heat Dissipation Issues in LED Lights


Many decorations have accepted costly LED light for their buildings. See LED Ceiling Down Light Bulb is gradually into a mature stage. Nearly two or three years ago, few people want to try using it because of knowing nothing in these expensive bulbs. After using LED lights for several months longer, the fact is that overall the transition has been good. Therefore, LED lights become more and more reliable on building industry.

However, compared with other lights, you may feel curious about what it is on the back side of LED bulbs. Most people now just know the LED (light-emitting diode), which is a small piece of diode. Think if just a small diode emitting light, why the bulbs are often larger than our imagination? All of these are the result of heat dissipation.

Like the other electrical equipment, when you are running fans or an air conditioner this summer, having burning-hot incandescent bulbs just makes it harder to manage the heat. LEDs run much cooler than incandescent bulbs and significantly cooler than CFLs. Heat dissipation is a key factor that limits the lumen output of an LED light. Generally, LED lights are available that energy efficient as 80% higher than traditional lights, but LED components and driver electronics still create a considerable amount of heat. Actually, LED light with a radiator just increases its using life. If this heat dissipated properly, the LED’s life would be decrease seriously.

Heat sinks solve thermal management problems for low-lumen LED lights such 6w LED bulbs lamps. Nevertheless, it is when you get into the high lumen counts that thermal management becomes a challenge. But this problem has been broken through the new technology. Moreover, the normal uses totally not need very high lumen lights because of the brightness itself.

As the mature technology, LEDs have been also used in various areas, we can see LEDs are applied to Strip light, 600Lm LED Headlamp and many others. So Heat Sink is a very vital part of LED lights.
