Cree Wolfspeed Semi-Conductor Technology – A Breakthrough in Lighting Efficiency
In the history of lighting, we’ve gone from burning whale oil and fats, to gas, to incandescent bulbs and finally to LEDs. Now there is a new step in lighting efficiency: Solid-state lighting (SSL) using gallium nitride semiconductor technology. Innovation continues in LED lighting technology for buildings and industrial applications. To meet market demand for smaller, smarter and more efficient light fixtures with higher luminous efficiency meaning they produce more light per watt. Manufacturers are increasing the amount of red and blue LEDs in new designs, but this creates challenges for manufacturers because the green spectrum cannot be produced efficiently by combining red and blue LEDs.
To meet these challenges, Cree Wolfspeed Semi-Conductor Technology, a breakthrough in lighting efficiency, is enabling increased luminous output from single LED devices as well as enabling double-ended LED chips that combine red, green and blue in one device. Read on to find out how!
What is Cree’s Wolfspeed Semi-Conductor Technology?
Cree Wolfspeed Semi-Conductor Technology is a breakthrough in lighting efficiency that increases light output from single LEDs as well as enabling double-ended LED chips that combine red, green and blue in one device. It is based on a new material technology that produces green light (530 nm wavelength) that is in high demand for indoor lighting and outdoor environment and traffic control applications. Wolfspeed Semi-Conductor Technology is a gallium nitride (GaN) semiconductor used to produce green light (530 nm) on a single chip. These are more efficient in delivering light than the current silicon-based semiconductors used in LEDs. Wolfspeed semiconductor technology is the only commercially viable solution for SSL with a pure GaN semiconductor. This will enable its technology to be the premier semiconductor material for SSL.
How Does Wolfspeed Semi-Conductor Technology Improve LED Lighting?
Wolfspeed GaN LEDs are more efficient in delivering light than the current silicon-based semiconductors used in LEDs. When using 10-watt GaN semiconductor technology, manufacturers can increase the amount of red and blue LEDs in new designs while still achieving the desired amount of green light needed for efficient lighting. This increases luminous efficiency, or the amount of light produced per watt of electrical power consumed, in the new design. This enables Cree’s Wolfspeed GaN technology to be the premier semiconductor material for SSL. When coupled with Cree’s leading edge single-die LED technology, Wolfspeed GaN semiconductor technology can help Cree lead the way in SSL. Learn more about downloads folder software
What are the Benefits of Wolfspeed Semi-Conductor Technology?
– Increased luminous efficiency – When using 10-watt GaN semiconductor technology, manufacturers can increase the amount of red and blue LEDs in new designs while still achieving the desired amount of green light needed for efficient lighting. This increases luminous efficiency, or the amount of light produced per watt of electrical power consumed, in the new design. – Reduction in heat – The increased amount of light produced by the new design is due to the cooling effect of the GaN semiconductor material. The higher thermal conductivity of GaN semiconductors and the absence of dielectric materials between GaN and the heat sink allow the Wolfspeed GaN LEDs to run cooler than existing silicon-based LEDs. – Single-ended LED chips – Wolfspeed GaN semiconductor technology can also enable double-ended LED chips that combine red, green and blue in one device. – Increased lifespan – Wolfspeed GaN LEDs have a projected lifespan of 50,000 hours, more than 15 times longer than silicon-based LEDs.
How does Wolfspeed Semi-Conductor Technology work?
Wolfspeed GaN semiconductor technology creates green light by passing electricity through it. When electricity passes through a material known as a semiconductor, it creates heat. When the semiconductor is heated to a certain temperature, crystalline defects form and cause the semiconductor to stop conducting electricity. The intensity of the light is related to the amount of current that passes through the semiconductor and the length of time it is on. When manufacturers use Wolfspeed GaN semiconductor technology to create green light, they can produce more light because the GaN semiconductor material has a higher thermal conductivity than silicon-based materials. Cree’s Wolfspeed GaN technology is a breakthrough in lighting efficiency that can help Cree lead the way in SSL.
