Abstract
An improved electric mirror lamp comprising a concave mirror on the focus of which a light source, for example an incandescent filament is fixed, and the lamp also includes locating means by which its position in a lamp holder is determined and support means holding the mirror at a fixed position relative to the locating means. A support mirror is an integral moulded body having portions adapted to position the locating of the mirror. The locating means may be constituted by a locating ring secured to an end cap and the support means may include indentations which engage and retain the end cap. The electric light source or bulb may be replaceable and the mirror may be formed directly on an appropriate concave surface of the support means.
