<p>In order to achieve the safety class II in accordance with the VDE specifications, an emitter which has a halogen lamp 4 capped at both ends and a metal reflector 2, which surrounds the lamp, is of approximately parabolic cross-section and in which the electric installations are accommodated in a totally insulated manner, is characterised in that a heat-proof, electrically insulating protecting glass 3 which extends approximately over the length of the lamp 4 is arranged between the halogen lamp 4 and the metal reflector 2. This protecting glass 3 renders it impossible for the lamp filament (coil) 42 to touch the metal reflector 2 should the lamp bulb melt through. <IMAGE></p> |
