  • Patent number: 5077648
    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.

  • Patent number: 4970627
    Abstract: A beacon lamp comprising a base, a support member fixed in relation to the base and a reflector carrier rotatably mounted on said support member for rotation relative thereto about a first axis. A drive motor carrier is resiliently supported by said support member such that in a rest position the principal axis of the motor carrier is disposed at a small angle to said first axis. An electric motor is supported by said drive motor carrier, and has its output member engaging a cylindrical wall of said reflector carrier, said motor carrier being deflected during positioning of said motor such that said principal axis is rendered substantially parallel with said first axis and said carrier resiliently biases the motor output member against said cylindrical wall of said reflector carrier.

  • Patent number: 4623959
    Abstract: For carrying out work during darkness by means of transloading vehicles on military field transloading posts, the apparatus for apron illumination while not making the post visible to undesired observers, comprises an apparatus casing with a light source arranged in its interior having an upstream-connected condenser lens and with a front lens, to which are connected two plane mirrors deflecting the optical path twice by 90.degree. with interposed inwardly and outwardly pivotable diaphragms and/or filters, an exit optics being arranged in the light beam passing out of the lower plane mirror.

  • Patent number: 4620267
    Abstract: The corrector device comprises at least one illumination sensor (10, a, b, c) integrated in a headlamp and fixed to move with the headlamp reflector (12), the sensor-reflector assembly normally pointing in such a direction as to detect the luminance of the road in at least one angular direction at a predetermined angle (o+.phi.+.theta.) with the horizontal (OY), with processing means being provided that are suitable for generating a corrector signal which is a function of the luminance of the road in said direction, whenever the trim of the vehicle changes, the device further including at least one actuator controlled by said corrector signal in order correct the direction in which the reflector-sensor assembly is pointing.

  • Patent number: 4616294
    Abstract: Disclosed is a reflector for an electronic flash device capable of changing the illuminating angle. The reflector is nearly of elliptical shape as in the case of the conventional one, wherein the ratio of the longer diameter of the ellipse to the shorter one and the shorter diameter itself are set at special values. Thus, the reflector can be designed small, while the same illuminating angle as in a case where a wide angle adapter is mounted on the flash device can be obtained.

  • Patent number: 4611266
    Abstract: The invention features a reflector for an electric bulb wall unit that diffuses and spreads the light over a wider area. The body of the reflector has a light diffusing semi-cylindrical center surface containing many diamond-studded projections. Surrounding the center surface are quarterly-spherical surfaces having saw-toothed striations that diffuse and spread the light in arcuate pathways.

  • Patent number: 4602320
    Abstract: Adjustable safety lamps for mounting upon a vehicle window, for example, the rear window of an automobile. Particularly, a "high set" brake lamp, including a frame together with adhesive means for securing the frame upon an automobile rear window; an outer housing having an open side secured at its perimeter to the frame and an inner housing, enclosing an energizable lamp. The inner housing is rotatably supported within the outer housing, such that the lamp is directed towards the open side of the outer housing and through the frame at eye level with respect to the driver of a vehicle approaching from the rear.
