Abstract
A light projecting device for selectively providing a light beam in at least two shapes. The light projecting device includes a light projecting source contained within a housing including a first end through which the light projecting source transmits a light beam. The device further includes a lens switch secured to the first end of the housing permitting the light beam to pass through a primary opening in the lens switch, while the lens switch controls the shape of the light beam projected from the light projecting device. The lens switch includes a first opening through which the light beam passes when the lens switch is in a first position to produce a first shaped light beam, a second opening through which the light beam passes when the lens switch is in a second position to produce a second shaped light beam, and a switching structure for selectively moving the first opening and the second opening between the first position and the second position to align the first opening and the second opening with the primary opening.
