Abstract

The lamp lights automatically on mains failure, and has batteries, low voltage bulbs and relay mounted in a housing of which the front part forms the projector. The rear part has a connecting plug screwing into a socket connected to the mains - or alternatively a bayonet-type connection can be used. The relay assures that as soon as mains failure occurs the batteries are switched to light the bulbs.
