DETAILED DESCRIPTION OF THE INVENTION

[0023] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0024] Broadly, embodiments of the present invention provides a headlight housing for customizing a motor vehicle with projection type lamps. As previously indicated, prior to the present invention the only way to mount a projector in a 7 vehicle headlight was to cut away a stock housing of the vehicle and epoxy the projector to the remaining housing piece. This invention eliminates the need to use a stock housing and reduces the amount of work needed to properly mount a projector and furthermore virtually eliminates the possibility of mounting the projector incorrectly.

[0025] The invention described here eliminates the need to cut the housing and align the projector, thereby eliminating any dust or debris. The result is a properly aligned projector, mounted securely with no mess created. The design results in a professional looking product using stronger materials for a longer expected life.

[0026] A headlight housing assembly of the present invention may be seen in reference to FIGS. 1, 11 and 12. The headlight housing assembly includes a headlight housing 10, shown in FIGS. 2-7, and a housing end cap 40, shown in reference to FIGS. 8-10. A projector or bulb 14may be mounted into the headlight housing assembly. The headlight wires 16 may be routed through the headlight housing 10 and through the housing end cap 40.

[0027] As seen in reference to FIG. 2, the headlight housing 10 has a substantially circular shape configured to be received in a motor vehicle headlight mount equipped with conventional round headlights. The headlight housing 10 has forward divergent end portion 18 and an aft cylindrical portion 20 extending from an aft surface of the divergent end portion 18. An annular rim 22 is defined at a front end of the divergent end portion 18. An annular frusto-conical beam reflector 24 portion is positioned inboard from and coaxial with the annular rim 22 opening. The beam reflector portion 24 has diverging sidewalls, which assist in focusing the light on a roadway.

[0028] A shoulder 25 is defined adjacent to the annular rim 22. The shoulder 25 is configured to support an optional halo lamp that may be carried in the headlight housing 10 anteriorly of and surrounding the projection lamp 14. Wiring 16 for the halo light may be carried through a bore 38 and the slotted opening 48 of the housing end cap 40.

[0029] Inboard from the reflector portion 24 is a mounting portion 26 having an annular sidewall generally aligned with a longitudinal axis the headlight housing 10. The annular sidewall of the mounting portion 26 is substantially coaxial with the annular rim 20 and beam reflector portion 24. An aft surface of the mounting portion 26 has a plurality of mounting holes 28 to receive fasteners for securing the headlight assembly to the motor vehicle.

[0030] The aft cylindrical portion 20 extends from an aft surface of the mounting portion 26 and has a substantially reduced radius from that of the forward divergent end 18. A back end of the cylindrical portion 20 has a projector mount 30. As best seen in reference to FIGS. 3-4, the projector mount 30 includes an annular depression 32 formed on an aft face of the cylindrical portion 20. The annular depression 32 is dimensioned to receive a forward annular face 42 of the housing end cap 40. The annular depression 32 circumscribes an interior projector depression 34 shaped to accept a base of a projector lamp 14. The projector depression 34 may have a keyed sidewall region for orienting the projector lamp 14 within the headlight housing 10.

[0031] A projection lamp aperture 36 is defined through a central region of the projector mount 30 and is dimensioned to receive a lamp portion of the projection lamp 14 there through. The projector mount 30 also has a plurality of bores 38 defined in a spaced apart relation around the periphery of the annular depression 32.

[0032] An endcap 40 is illustrated in reference to FIGS. 8-10 having a front surface with an annular depression 44 formed within the forward annular face 42 to receive a back surface of a base of a projector lamp 14. A center opening 46 is defined in the annular depression 44 to receive a terminal end of the projector lamp 14. A slotted opening 48 is defined at the periphery of the depression and is configured to receive wiring for connection of the projector lamp 14. A plurality of flanges 50 extend from the periphery of the endcap 40 and are disposed so that a fastener opening 52 is aligned with the plurality of bores 54 at the back of the headlight housing 10.

[0033] The housing end cap 40 is then pressed into place and secured with screws completing the seal, protecting the wires 16. The slotted opening 48 permits the wiring 16 to be carried through the endcap 40 and twisting of the endcap 40 to secure it within the aft end of the projector mount 30, thereby and preventing water intrusion, ensuring a proper fitment into the headlight bucket, and resulting in a professional looking installation. A rubber gasket may be applied between the headlight housing 10 and the end cap 40 to improve the seal of the projection lamp 14 mounted within the headlight housing 10.

[0034] The housing 10 should be installed into the vehicle's headlight bucket using the markings on the housing, ensuring the arrow pointing UP is set at the 12 oclock position. The housing will then fit into the bucket allowing for horizontal adjustments and vertical adjustments to ensure a proper beam pattern.

[0035] While the invention has been described in relation to an adaptation for motor vehicles, the housing can also be adapted to be used for home lighting as well. Such uses include custom made automotive themed lighting (i.e. using an old Jeep Grill to mount incandescent light bulbs).

[0036] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
