Automobile headlight with combined heat and light shield

Claim 2

In an automobile headlight including a reflector, a plastic lens secured to said reflector, and a light source in the form of a capsule disposed within and substantially surrounded by said reflector, the improvement comprising: means located on or forming part of a preselected portion of said plastic lens for preventing transmission of visible light through said preselected portion of said lens to reduce glare when said headlight is in operation in an automobile and for preventing heat buildup on said lens during said operation, said means located adjacent said capsule and preventing direct light from a portion of said capsule from passing through said lens, said means including a layer of heat insulating material located on an internal surface of said lens relative to said capsule light source and means for absorbing visible light and reflecting heat upon receipt of said visible light, said light absorbing and heat reflecting means located on said layer of heat insulating material.

Claim 3

The improvement according to claim 1 further including emblem means secured to an external surface of said lens relative to said means for preventing light transmission and heat buildup.

Claim 4

The improvement according to claim 1 wherein said heat insulating material is mica and said light absorbing and heat reflecting means comprises a layer of aluminum located on said mica and having a dark coating thereon.

Claim 5

The improvement according to claim 3 wherein said dark coating is black paint.

Claim 6

In an automobile headlight including a reflector, a plastic lens secured to said reflector, and a light source in the form of a capsule disposed within and substantially surrounded by said reflector, the improvement comprising: means located on or forming part of a preselected portion of said plastic lens for preventing transmission of visible light through said preselected portion of said lens to reduce glare when said headlight is in operation in an automobile and for preventing heat buildup on said lens during said operation, said means located adjacent said capsule and preventing direct light from a portion of said capsule from passing through said lens. said means for preventing light transmission and heat buildup including a layer of heat reflecting material located on an internal surface of said lens relative to said light source, heat insulating means located adjacent said layer of heat reflecting material, and means for absorbing visible light and reflecting heat upon receipt of said visible light, said light absorbing and heat reflecting means spaced from said layer of heat reflecting material by said heat insulating means.

Claim 7

In an automobile headlight including a reflector, a plastic lens secured to said reflector, and a light source in the form of a capsule disposed within and substantially surrounded by said reflector, the improvement comprising: means located on or forming part of a preselected portion of said plastic lens for preventing transmission of visible light through said preselected portion of said lens to reduce glare when said headlight is in operation in an automobile and for preventing heat buildup on said lens during said operation, said means located adjacent said capsule and preventing direct light from a portion of said capsule from passing through said lens. said means for preventing light transmission and heat buildup including a layer of heat reflecting material located on an internal surface of said lens relative to said light source, heat insulating means located adjacent said layer of heat reflecting material, and means for absorbing visible light and reflecting heat upon receipt of said visible light, said light absorbing and heat reflecting means spaced from said layer of heat reflecting material by said heat insulating means.

Claim 8

The improvement according to claim 5 wherein said heat reflecting material includes a first layer of aluminum, said light absorbing and heat reflecting means comprises a second layer of aluminum having a dark coating thereon, and said heat insulating means includes a substantially open area through which the internal atmosphere of said headlight can pass during said headlight operation.

Claim 9

The improvement according to claim 6 wherein said dark coating is black paint.

Claim 10

The improvement according to claim 6 further including a plurality of support rods secured at one end to said first layer of aluminum in a spaced-apart relationship, said second layer of aluminum being positioned on a second, opposing end of each of said support rods, said atmosphere of said headlight passing around and between said support rods.

Claim 11

The improvement according to claim 8 wherein each of said support rods is comprised of plastic.

Claim 12

The improvement according to claim 1 wherein said capsule comprises a tungsten halogen capsule located substantially along the optical axis of said reflector in a direction toward said lens, said means for preventing light transmission and heat buildup being centrally disposed on said lens.

Claim 13

The improvement according to claim 2 wherein said emblem means passes through both said plastic lens and said means for preventing light transmission and heat buildup for securing said means on said internal surface of said lens.

Claim 14

The improvement according to claim 2 wherein said emblem means is plastic.
