Abstract: A light fixture having a base coupled to a housing by means of a coupling of the ball and socket type. The light housing may be fixed in any angular orientation over a range of azimuth angles well in excess of two hundred and seventy degrees and any angle of elevation from completely horizontal to completely vertical. The coupling can do so while accommodating the passage of electrical conductors from the base of the fixture extending toward the lamp and while also protecting the fixture against misuse in the form of repeated rotation tending to disconnect those conductors internally of the fixture. Altering the relative positions of a lamp and reflector changes the width of the beam cast by the apparatus. With the reflector and front lens fixed, a lamp holder is mounted for sliding motion with respect to the rear of the housing and is moved by manual actuation of a mechanism accessible from the rear of the fixture.

Abstract: In a slant type headlamp unit for motor vehicles, the reflector has an inner reflecting surface a reflecting area taking the form of a part of a paraboloid of revolution and a light-diverging reflecting area which diverges in the horizontal plane, and a reflects in the vertical plane the rays of light incident from a lamp bulb in directions substantially parallel with the optical axis. The center of the filament of the lamp bulb is disposed nearly parallelly with the optical axis of the reflector and as spaced slightly frontwardly from the focus of the paraboloid of revolution. A front lens is disposed as slanted with respect to said optical axis, covering the front opening of said reflector and having provided on the inner surface by a plurality of prism areas which refract the rays of light emitted from said lamp bulb and reflected at said reflector, thereby forming horizontally elongated illumination patterns and slant illumination patterns frontwardly.

Abstract: A mechanism for adjusting the orientation of vehicle headlamps or the like includes a molded gear housing having a gear journaling bore for rotation of an adjusting gear journaled therein, and an adjusting member movably coupled to the adjusting gear such that rotation of the adjusting gear imparts linear movement to the adjusting member for the headlamp adjustment. The housing also includes aperture means through which the adjustment member slidably extends, and the aperture means cooperates to prevent rotation of the adjusting member during the linear movement thereof. Additional features of the preferred adjusting mechanism provide a drive shaft and drive gear meshed to drive rotation of the adjusting gear. The drive shaft extends through a cap portion of the housing for manual access to the shaft, and the cap bears against an annular retainer portion on the drive shaft in order to prevent retraction of the shaft from the drive gear and the housing.

Abstract: A glare control lamp and reflector assembly and method for glare control which includes a conventional lamp and symmetrical reflector for providing a controlled light beam to a target area. A reflector shield can be positioned on the reflector below the lamp and has the properties of diverging incident light downwardly towards the target area and thus controls reflection upwardly which would produce glare. A glare shield can be positioned on the top of the reflector and extends outwardly from the outer edge of the reflector to block both direct light and reflected light from traveling upwardly and outwardly which would produce glare. In a further combination, a lamp shield can be positioned over a portion of the outermost extending end of the lamp to prevent unreflected light from directly causing glare.
