Researchers Taste Success In Developing Next-generation LED?

Researchers at the SLERC (Smart Lighting Engineering Research Center) at the Rensselaer Polytechnic Institute have tasted success integrating an LED on a gallium nitride (GaN) chip. Market analysts predict that this breakthrough in technology could lead to a new-generation of LED technology which is not so expensive to manufacture and is also comparatively more efficient than the others. These next generation LEDs are capable of enabling new functionalities as well as applications that are far beyond lighting.

The main focus of present day’s light-emitting diode lighting systems is the chips that are made from a semiconductor material known as GaN. It should be understood that in order for the LED lighting systems to function, there are numerous external components that need to be integrated into the chip, and these include the capacitors, inductors, silicon interconnects, and wires.

LED lighting systems get simpler design?

Thus, the size of the chip gets really large and it is difficult to manage with so many components that further complicate the design and impact the performance of LED products .  Besides that, there’s the process of assembling all these intricate LED lighting systems that can further make the process time consuming, manually intensive, and also quite expensive.

In a recent study that was led by T. Paul Chow, the eminent professor at Rensselaer from the Department of Electrical, Computer, and Systems Engineering, the researchers discovered that this challenge could be resolved by developing an innovative chip that comprises of components made from GaN. This monolithically integrated chip aids in simplifying the entire process as there are less assembly steps, thus less automation.

New LED devices will have fewer malfunctions?

Chow also said that the LED devices that will be made using the innovative new integrated chips will have fewer parts to malfunction, thus the efficiency will be high and the products will also be very cost effectiveness with improved flexibility of lighting design. The team comprising of Chow and the research team developed a GaN LED structure that grew on a sapphire substrate.

Chow said that this is just the beginning and hopefully the future will see more improvements like this that will make the LED devices easily available at affordable prices.
