The light bulb

When Mickey Mouse gets an idea a light bulb pops up above his head. It has become a symbol of inventions and ideas. The American, Thomas Edison, who was afraid of the dark, first succeeded in constructing light bulbs in 1879 in collaboration with Joseph Swan. With electric lighting people´s lifestyles changed. Suddenly people could read and work long into the evenings. Homes were furnished in new ways as there was no longer the risk of falling over things in the dark and towns and cities were lit up by advertising signs.

A light bulb converts just 5 % of the energy it uses into light, the rest turns into heat. To save energy, the EU has decided that the light bulb will be phased out. In 2013 it will be replaced by halogen, fluorescent and LED lighting.
