A lamp comprising a base ( 10 ) having separate parts ( 11, 12 ) which may be brought together around, and to make contact with, an electrical supply cable ( 13 ). In the base ( 10 ) there is provided one or more LEDs and electrical circuitry, and a solid acrylic rod ( 18 ) is mounted in the base to receive light from the or each LED. The total internal reflection within the rod, and the lensing effect of a domed upper end ( 19 ) produce a beam of light equivalent to a standard incandescent light bulb but with low power input and increased durability when compared with an incandescent bulb. Several such lamps may be grouped together to form a downlighter, or spaced apart along the supply cable ( 13 ) and mounted externally on a building for decoration and display purposes. |
