Abstract
Official abstract text for this publication.
An electric lamp ( 1 ) comprising a socket ( 2 ), a lamp bulb ( 4 ) mounted on the socket, in which bulb at least one semiconductor light source ( 5 ) is arranged. Cooling means ( 6 ) comprise at least two facing cooling fins ( 7,8 ) which are separated by at least one spacing ( 9 ). Said spacing being open to the environment and extending from the heart of the lamp bulb to the outer surface of the bulb. The lamp comprises a light redistributing, light transmittable wall ( 13 ) for redistributing light; optionally said light redistributing wall comprises separate, discernable wall parts ( 14,15 ). For example, each discernable bulb part is shaped like a surface of a half prolate or half oblate ellipse. Thus, a desired double beam or homogeneous, omni-directional light distribution is obtainable.
