Various embodiments may relate to a semiconductor retrofit bulb, in particular a retrofit festoon bulb, having connecting elements that are arranged on two sides. The semiconductor retrofit bulb may include at least a tubular cooling body having at least one outer face support surface, wherein there is arranged on the support surface at least one semiconductor light source, in particular a light diode, a driver housing that is introduced into a hollow space of the tubular cooling body. At least one flow channel is provided between the driver housing and the cooling body.

Semiconductor retrofit lamp having connecting elements arranged on two sides

A semiconductor lamp includes a reflector having a lower side and an upper side, wherein the lower side widens laterally and wherein the lower side and the upper side are separated from one another by an upper rim, and having a first light source group having at least one semiconductor light source and a second light source group having at least one semiconductor light source, wherein the reflector is provided as a cooling body for the first light source group and for the second light source group; wherein at least a part of a light that can be emitted by the first light source group can be reflected by means of the lower side of the reflector at least into a spatial angle range that cannot be directly illuminated by the first light source group.
