Abstract
An automotive headlamp is housed within a rotatable spherical shield so that light-diminishing road debris such as slush accumulates on the shield and not the headlamp. Wipers are mounted in wiping relation to the shield so that the debris is removed when the shield is rotated. A switch in the passenger compartment of a vehicle allows the driver to rotate the spherical shield as needed, and cleaning fluid is housed within a reservoir to enable operation of the mechanism over extended periods of time.
Claims8
A device for protecting a light source, comprising:
- a transparent, spherical in configuration shield member;
- a hollow axle member disposed in diametrically extending relation to said shield member, said axle member having opposite ends fixedly secured to said shield member so that rotation of said axle member effects simultaneous and corresponding rotation of said shield member, and said axle member being discontinuous along its middle part;
- motor means for selectively activating rotation of said axle member;
- a hollow, non-rotatable tube that is received within said hollow axle member;
- said light source being mounted to said non-rotatable tube;
- said non-rotatable tube having opposite ends that penetrate and extend outwardly of said shield member;
- said light source being conductively coupled to a source of power by electrical conductors that extend from said source of power to said light source through said hollow, non-rotatable tube;
- whereby said light source is completely surrounded by said spherical shield member and protected thereby.
