The outer edge of the reflector has a plurality of recesses or openings in which the springs are mounted, which engage behind the front of the cover with a projection. The free legs of the U-shaped springs are pushed through the opening in the reflector edge to the front of the luminaire and locked so that they carry themselves.

From the DE 197 57 055 A1 is a lamp with a cylindrical housing, a reflector and a arranged on the front of the housing glass holder with at least one circular glass sheet known. The glass holder consists of two diametrically attached to the front side of the housing glass retaining springs, which have a formed from spring plate spring body with an arcuately curved front and U-shaped adjoining the front leg, whose ends are formed into eyelets. The arcuately curved front side of the glass retaining springs has in the circumferential direction of the housing longitudinal slots which define resilient strips which are curved to form a Glasscheibeneinfassung arcuately outwardly in an arcuate outward to the spring body outside and inwards to the back of the spring body, so that the glass sheet in the thus formed Recesses of the glass retaining springs can be used radially. At the periphery of the housing, a sliding ring is additionally arranged as a glare shield, which is spring-loaded relative to the housing of the lamp and displaceable over the glass retaining springs.

The spring elements are arranged distributed on the circumference of the headlamp device, designed to be resilient in the radial direction of the headlight housing and connected via fastening straps or fastening arms with the headlight housing. With the elastic strips and two adjacent to the side edge of the headlamp device spring arms are angled.
