Abstract
A lamp having a treated lense for reducing peripheral glare thereby making the lamp useful as a driving light, fog light or spotlight. The treated lense is provided with opaque pigment around the periphery of the lense and the center portion thereof to form elliptical shaped aperture for more acutely defining the desired beam pattern.
Claims13
A modified lamp for emitting a beam of light, the lamp having a parabolic reflector, a light emitter located near the focus of the parabolic reflector, and a lense element covering the reflector and the light emitter;
- the modification comprising the lense element having two selected areas of opaque coating for reducing peripheral glare thereby shaping the beam pattern, the first area of opaque being around the outer periphery of the lense element, the second area of opaque coating covering the center portion of the lense element leaving a light aperture area interposed between the first and second areas of opaque coating, the first and second areas of opaque coating being shaped to cooperate with the lense element structure to reduce the outer periphery of light emitted from the lamp.
A vehicle driving lamp comprising a lamp for producing a beam of light directed forward of the vehicle, the lamp having a lense element, a first area of opaque coating provided around the outer portion of the lense element leaving an elliptical uncoated area interior of said first coated area, a second elliptical shaped area of opaque coating being concentrically disposed within the elliptical uncoated area forming an aperture between said coated areas which is also elliptical in shape.
