Abstract

A light source arranged to be illuminated automatically upon failure of the normal electricity supply to a room, building or the like. The light source comprises a lamp housing 12 containing a bulb 18, batteries 30,32 and switch, and a base 14 on which the lamp housing can be mounted. One part 42 of an electromagnet including an energising winding 44 is mounted in the base and the other part 28 is mounted in the torch housing such that when the housing is mounted on the base and an a.c. supply is connected to the base the two parts of the electromagnet are mutually attracted and the housing is held securely on the base. If the a.c. supply is interrupted the electromagnet is de-energised, allowing the housing to be removed from the base and, at the same time, the switch is operated to connect the batteries to supply current to the bulb. <IMAGE>
