Lamp e.g. head lamp, for e.g. motor cycle, has cooling device combined with light source units and provided at housing from interior to exterior of housing, and ribs arranged in vertical direction in distances to exterior of housing

摘要

The lamp has light source units comprising a light emitting diode and a lens that is arranged in front of the light emitting diode. A housing accommodates the light source units, and a cooling device dissipates heat generated by the light source units for cooling. The device is combined with the light source units, and is provided at the housing from interior to exterior of the housing. The device has ribs (46) arranged in a vertical direction in distances to the exterior of the housing. Rods (48) are formed in such a manner that the rods are curved along an exterior wall of the housing.
