n LED
A light-emitting diode used in television sets, video recorders, CD players, calcu-
lators, measuring equipment and in some computers etc. LEDs emit light when
activated by electric current. They have many applications. A refined form of LED
has been developed in London which by means of its strong red light emitted at
exactly 680 nanometres can activate drugs which are able to get rid of bacterial
infections such as stomach ulcers. A fireman has invented a torch with 12 red LEDs
which will make it possible to see through clouds of smoke in a way the white
light of an ordinary torch cannot. This relies on the principle that red light can
be seen more easily than other colours because it is not subject to being dispersed
as much by particles in the atmosphere. The light emitted can also detect fires.

by veterinary surgeons. See LED and colour therapy.
