Abstract: Thin panel illuminator includes a solid transparent panel member having one or more deformed output regions which cause light entering the panel along an input edge thereof to be emitted along the length of the panel. Light may be transmitted to one or more panel input edges from one or more light sources utilizing transition devices which convert easily focused light generally to the shape of the panel input surfaces.

Abstract: The invention relates to an improvement in light fixtures of the type having a base, a socket receiving a bulb, and a primary reflector defined on the base located in relatively close proximity to the bulb. The improvement consists of a secondary reflector located between the primary reflector and the bulb. The secondary reflector is closely spaced from the primary reflector defining an air gap therebetween. The secondary reflector provides dispersion of concentrated heat produced by the bulb to maintain the primary reflector at a lower temperature whereby the air gap reduces heat transfer between the reflectors, and the secondary reflector is formed of a reflective material to provide improved light reflectance qualities.

Abstract: Structure for the all-around display of a flat image over an angle of 360.degree.. The image should be visible with a continuous luminous intensity, regardless of the rotary speed. According to the invention, the maximum variation of the luminous flux from the light source--as a function of the rotary speed--must not reach a degree which is detectable by the human visual apparatus. Advantage is taken of the sluggishness of the human visual apparatus if, during each complete revolution of the image carrier through 360.degree., the total time of all bright phases is at least 30%, preferably at least 50%, in particular at least 70%, of the time of a revolution of the image carrier, and/or if the frequency of the bright phases is at least 200 Hz, the bright phases preferably emitting at least 75%, in particular at least 90%, of the maximum luminous intensity.

Abstract: An attachment for a flashlight for changing a narrow beam light output into a wide beam output. A hollow three dimensional reflector intercepts light rays coming from the flashlight, and redirects such rays into a series of fan-shaped patterns measured in radial planes containing the flashlight axis. A small central opening in the reflector transmits some rays in the forward (axial) direction. The attachment is useful during camping trips for illuminating the space within a tent enclosure.

Abstract: A self-balanced multiposition holder (10), particularly for a lamp (16) comprises a circular sector-like base (12) and an arm (14) attached to the base. At its end opposite to the lamp, the arm is attached to a counterweight (20), which in assembled state of the unit is hidden inside the base. The center of gravity of the entire unit is located at the center of the circle of the above-mentioned sector which forms the base, and the weight of the base, together with the counterweight is balanced by the weight of the arm with the lamp shade and lamp. Thus, when the holder is inclined at any position by rolling it on the circular bottom surface of the base, it remains at equilibrium in any position within its range of rotation.

Abstract: The flashing light apparatus is an improved technique of advertising and of gaining the public's attention for the purpose of increasing the sale of newpapers. The flashing light is a single or dual light mounted on the front of a venting machine where it will easily catch the eye of the passing public. A timer push button switch is mounted on the inner partition wall, just inside the door, for easy access and activation of the light. Once the timer switch is manually activated, the light/lights will flash two and one half (21/2) hours to alert the public that the late edition of the newspaper has arrived. The source of power for operation of the flashing light apparatus is a 6 volt lattern battery and is enclosed in a metal or plastic container which is mounted on the inside left wall as depicted in FIG. 1. The electrical circuit can be installed aft of the flashing light or it may be placed in the battery container.

Abstract: A decorative trim lighting system comprises an elongated, extruded plastic retaining strip which is formed in a laterally folded configuration and is adhesively securable along an exterior edge portion of a building. A series of support tab members are insertable between the folded side portions of the retaining strip, at longitudinally spaced intervals along the strip, and are frictionally gripped and retained by the facing side portions of the strip. The tabs have outer end portions which support the light elements of a decorative light string along the building portion edge. The retaining strip may be left in place on the building when the light string and associated support tabs are removed, and permits rapid and easy reinstallation of the light string. Additionally, the spacing between the individual light elements may be easily adjusted simply by sliding their support tabs along the length of the retaining strip.
