A lighting device includes a heat sink, through which air can flow transversely to its longitudinal extension and a plurality of semiconductor light sources, in particular light-emitting diodes, arranged on the heat sink, wherein at least two of the semiconductor light sources are aligned in different directions.

Lighting device

A bulb for a semiconductor luminous device is provided. The bulb is three-dimensionally extended and includes at least one optically effective surface structure. A semiconductor luminous device may include at least one semiconductor light source and an optically transmissive bulb for transmitting light emitted by the at least one semiconductor light source, the bulb being three-dimensionally extended and comprising at least one optically effective surface structure, wherein the bulb encloses at least one semiconductor light source.

Bulb for semiconductor luminous device, and semiconductor luminous device

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.
