The Little Blue LED that can Help Save the Planet

The Little Blue LED that can Help Save the Planet

During October half-term (24th October – 1st November), we have a sparkling week full of activities to celebrate the International Year of Light 2015, and on Wednesday 28th October we have a special talk on the little blue LED that can help save the planet. With guest speakers, Professor Gareth Parry (a Museum volunteer) and Ivor Corkell (from ShelterBox).

Did you know?… More than a billion people across the globe do not have access to electric lighting. The invention of LED lighting is helping to change this whilst reducing our need for electricity.

Before the advent of LED lighting at least 20% of electricity generated in industrial economies was used for lighting. Widespread use of LEDs will reduce this to 4% and consequently reduce our need for power stations with consequential beneficial reductions in greenhouse gas emissions. The component that makes this possible is the extremely efficient blue light emitting diode. The blue light from the diode is converted to white light (daylight) using materials called phosphors in a compact housing that is used in today’s lights.
Around 2010 a US company, LuminAID, came up with the idea of using LED lights in disaster zones created by earthquakes or typhoons. Not only could they be powered using solar energy but they could be packed densely to minimise transport costs. In November 2013 ShelterBox distributed more than 30,000 LuminAID lights to victims of Typhoon Haiyan in south-east Asia.

Join Professor Gareth Parry, and Ivor Corkell to explore LED lights use in disaster zones.

The talk is free with Museum admission, and there will be two talks starting at 2pm and 3pm. Head to the demonstration area of museum.
