The halogen bulb holder (3) of the light is held by a support that consists of two U-shaped profile parts (6, 7) at a distance behind the reflector (1) that can be selected by moving the second U-shaped profile part (7). The reflector (1) incorporates an opening (2), through which the halogen bulb (4) extends into the reflector space (20). The cross-section of the opening (2) is a multiple of the cross-section of the halogen bulb, so that a broad annular gap (21) for air circulation is left unobstructed between the halogen bulb (4) and the opening edge (9) of the reflector (1). The support (6, 7) is completely open to the rear and in addition on two opposing sides so as to form an air circulation space (22). The halogen bulb holder (3) is freely supported by the support (6, 7) in the air circulation space (22) that is adjacent to the annular gap (21), so that the air that flows through the annular gap (21) passes around the holder (3) and the base (foot) of the halogen bulb is cooled thereby. This increases the service life of the halogen lights to a considerable extent. Figure 2. |
