Abstract

The opening in the bowl-shaped plastic reflector is surrounded by a collar. Inserted into the collar is an incandescent lamp with a flange that surrounds its base and rests against the face of the collar. The lamp is secured to the reflector with a wire spring that is bent along the optical axis into the shape of a U at the rear of the reflector. The two legs of the spring are tensioned against opposite sides of the collar. The free ends of the legs rotate in a mount. Another mount is positioned on the other side of the collar and has a projection that extends out more or less radially in relation to the optical axis of the reflector and creates an undercut. The web that connects the legs automatically snaps into the undercut. The web has a lever in the form of a bent-in eye that rotates when forced down along the optical axis around a section of the second mount that parallels the web of the spring.
