Energy-Efficient Gallium Nitride LED Lighting

This video shows Prof. Sir Colin Humphreys explaining the benefits of using gallium nitride in LED lighting. The research on gallium nitride has led to some key developments in LED technology. Colin Humphreys, along with his team, has been growing gallium nitride LEDs on silicon, instead of on sapphire, to make LEDs more affordable and energy efficient for homes and offices. These gallium nitride LED chips on silicon are being produced in the UK for use in microscopy.
