Light-emitting diodes, or LEDs, are an energy-efficient source of light. They have several advantages over incandescent and fluorescent lights: they are more energy-efficient and last longer. But LEDs are not perfect, and they could be better.
Problems with current LEDs
One problem with current LEDs is that they generate heat, albeit not nearly as much as incandescent bulbs. If you have an LED light and have ever held your hand close to it, you will know that it doesn’t get very hot. However, according to EurekAlert, in situations that require intense lighting, such as vehicle headlights and stadium lighting, LEDs can become excessively hot, which can cause problems.
LEDs get hot because the portion of energy that isn’t used to produce light is converted into heat instead. This causes the LED to become hot, which changes its properties. It may become less energy efficient or change color slightly.
Using computers to search for better LEDs
A chemistry professor at the University of Houston has been awarded a $656,000 NSF grant to investigate this problem. Professor Jakoah Brgoch utilizes computers to gain a deeper understanding of chemistry. What do computers have to do with chemistry? By creating simulations, chemists can explore various models of how specific chemicals interact with one another. Or, as in this case, they can explore how different materials would behave at various temperatures.
This research aims to identify LEDs that perform well at low temperatures and remain functional at high temperatures. In a few years, this technology may come to market and could be beneficial for various situations that require intense light. If that does happen, Relumination will be there to help you choose the best option for your business. Please contact us if you have any questions about LED lighting.
