Abstract: The optical body of the invention receives light given off by a light source into a conical spatial region with a central axis extending in the Z-direction. The optical body is substantially V-shaped in a section plane defined by the Z-direction and a X-direction perpendicular thereto. The limbs of the V-shape which respectively have outside and inside wall regions are arranged symmetrically relative to the central axis and converge towards a base portion of the optical body. To achieve uniform light distribution the base portion has a recess of such a depth that a light source whose light cone has an apex angle of approximately 180° extends into the recess to such a degree that substantially all its light is coupled into the optical body.

At least one light emitting diode is arranged in the housing laterally of the light cover, its main emission direction being substantially parallel to the longitudinal direction of the light cover. Light from the diode in the main emission direction is coupled into a light guide and is at least partially coupled out transversely with respect to said main emission direction towards the light cover. A reflector arrangement which extends at least on the side of the light guide in opposite relationship to the light cover reflects towards the light cover light coupled out therefrom in other directions than towards the light cover. The reflector arrangement includes a good heat-conducting material and is in good heat-conducting relationship with the diode to dissipate heat therefrom.
