Abstract

A headlamp having minimal glare, composed of a housing having preferably a non-reflective interior, an electric bulb located within the housing and a simple convex lens mounted to the housing and through which external illumination is provided. For purposes of incrementing the illumination output, a flat mirror is placed rearwardly of the electric bulb. According to this structural configuration, no concentrated beams of light are created, and illumination is pleasingly uniform and of minimal glare.

Claims

1. An electric light having minimal glare characteristics, said electric light being interconnected with a source of electricity, said electric light comprising:

a housing having an aperture, said housing having an interior wall surface, said interior wall surface being non-reflective;

an electric light bulb located within said housing, said electric light bulb being mounted with respect to said housing; and

a lens mounted with respect to said housing at said aperture, said lens being a simple convex lens, said lens having an optical axis, said electric light bulb being located with respect to said lens along said optical axis such that light emitted from said electric light bulb is focused by said lens;

wherein all surfaces located within said housing are non-reflective;

wherein said electric light bulb emits light when the source of electricity is activated with respect to the electric light bulb, and further wherein illumination is provided by said light exiting from said lens.

2. The electric light of claim 1, wherein said lens is located with respect to said electric light bulb such that light emitted from said electric light bulb is optimally focused by said lens to provide illumination.

3. The electric light of claim 1, further comprising electrical socket means for connecting said electric light bulb to said housing.

4. The electric light of claim 3, wherein said electrical socket means is mounted with respect to said housing so that said electric light bulb mounts to said electrical socket means in a direction parallel with respect to said optical axis of said lens;

further wherein said electric light bulb is a standard socket mount electric light bulb.

5. An electric light having minimal glare characteristics, said electric light being interconnected with a source of electricity, said electric light comprising:

a housing having an aperture, said housing having an interior wall surface, said interior wall surface being non-reflective;

an electric light bulb located within said housing, said electric light bulb being mounted with respect to said housing;

a lens mounted with respect to said housing at said aperture, said lens being a simple convex lens, said lens having an optical axis, said electric light bulb being located with respect to said lens along said optical axis such that light emitted from said electric light bulb is focused by said lens; and

a flat reflector mounted to said housing adjacent said electric light bulb opposite said lens at a location along said optical axis;

wherein all surfaces located within said housing are non-reflective except with respect to said flat reflector;

wherein said electric light bulb emits light when the source of electricity is activated with respect to the electric light bulb, further wherein illumination is provided by said light exiting from said lens.

6. The electric light of claim 5, wherein said lens is located with respect to said electric light bulb and said flat reflector such that light emitted from said electric light bulb and reflected by said flat reflector is optimally focused by said lens.

7. The electric light of claim 6, further comprising electrical socket means for connecting said electric light bulb to said housing.

8. The electric light of claim 7, wherein said electrical socket means is mounted with respect to said housing so that said electric light bulb mounts to said electrical socket means in a direction perpendicular with respect to said optical axis of said lens;

further wherein said electric light is a standard socket mount electric light bulb.
