What is the relationship between silicone resin and LED?

Dec 27, 2019

Around us, the application of light-emitting diodes (LEDs) is becoming more and more widespread. They can provide backlighting for communication keyboards ... and they are becoming more and more popular in large flat-panel displays ... helping improve safety when used in car brake lights and turn signals. LEDs are "instant light" devices. When you are traveling at a speed of 96 km / h (60 mph), if the car in front of you is equipped with LED brake lights, you will get an additional 4.6 meters (15 feet) of braking time.

The LED industry is seeking to improve the light output, reliability and lifetime of LEDs and devices using LED technology. Silicone encapsulants can provide these benefits while minimizing their environmental impact.

LED semiconductor "chips" are packaged in a variety of structures that emit specific colors of light. The chip must be packaged to increase direct light output and protect the chip from dust, moisture, and mechanical damage. Traditional encapsulation materials such as epoxy are easy to discolor, and there are restrictions on the soldering temperature, so the application of LED technology has been limited. Customers' favorite high-brightness LEDs will generate too much heat on the chip surface, which will have a more adverse effect on the surrounding potting compound.

However, silicone resins can absorb heat. At present, high-brightness LEDs packaged in silicone are increasingly used in mobile phones, televisions, computer screens, traffic lights, automotive interior and exterior lighting and other applications.
