Abstract (en)
[origin: EP2314912A1] The bulb has a lens plate (4) provided with multiple fresnel lens. The lens plate is guided in a distance to a carrier plate (8) using vertical guidance units (7). The lens plate is arranged in a retaining ring (1), where an outer contour of the retainer ring intervenes into a guide winding of a guiding ring (2). The retaining ring with the lens plate is secured against rotation motion of the guiding ring by the guidance units, during rotation of the guiding ring. The retaining ring is moved on the carrier plate or moved away from the carrier plate depending upon a rotation direction.
