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 into the outer surface of the bulb. The lamp comprising 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 as a surface of a halve prolate or halve oblate ellipse. Thus a desired double beam or homogeneous, omni-directional light distribution is obtainable. |
