of gas or vapour at a low pressure. In these lamps light is obtained by applying an electric potential difference to a gas or vapour contained by the lamp under a suitable pressure. Due to application of electric potential difference gas gets ionised and an electric current flows; the tube is filled with a luminous discharge. The light spectrum obtained is however discontinuous (i.e. it consists of one or more coloured line). The colour of the light obtained depends upon the nature of the gas or vapour

Glazing is a way of changed the glass so that the light reflects off the window or absorbs the light and brings it into the building. Photo-chromic is the best product for glazing‚ as it can be switched so that it both reflects the light and absorbs it. Photo-chromic is a product called a switchable glazing.

With only 3 employees and himself he produced and sold the light bulbs from his home in Osaka. Matsushita’s idea was so highly regarded he had to rent his neighbour’s house to keep up with demand.
