Zusammenfassung: | By a reflector (1), which consists of a polymeric material, essential improvement of thermal condition in the interior thereof is achieved, so that despite to long-term operation the wall (10) thereof, which cosists of a polymeric material, cannot be over-heated in the hotest zone in the upper area (11) above the bulb (4), and moreover the negative effects, which result from the presence of an essentially cooler zone in the lower area (12) below the bulb (4), may also be avoided. According to the invention is the thickness (D) of the wall (10), which consists of a thermo-insulating polymeric material, in the upper area (11) above the portion (100) of inserting the bulb (4) smaller than the thickness (D2) of the wall (10) in the lower area (12) of the shell (3), below the portion (100) of insertion the bulb (4). As one of further possible measures, an opening (22) may be foreseen in the top area of a carrying ring (2), which is positioned at the maximum distance from the equatorial plane (30), or adjacent to this area. |
