  • Patent number: 11131449
    Abstract: The present invention relates to a lighting device including a light transmittable shell, a conductive unit and a light source. The light transmittable shell has an inner space and a mounting opening connected to the inner space. The light source is mounted around the mounting opening such that the LEDs in the light source are arranged along the edge of the mounting opening. The light from the light source transmits through the light transmittable shell from the edge of the mounting opening, leading to a glowing effect of the light transmittable shell, improving the lighting efficiency of the lighting device. Furthermore, the LEDs are distributed along the edge of the mounting opening and have direct contact with the flowing air in open space, so the heat-dissipation of the LEDs is effective enough without extra cooling components.

  • Patent number: 9520071
    Abstract: A display system employs an active image-generating screen (102) that presents a video image. The screen contains a plurality of block facets (112), each containing a plurality of light-emissive modules (114) preferably implemented with LEDs. Each light-emissive module is configured so that the maximum intensity of that module's light emission occurs along a direction (138) materially non-perpendicular to the back surface (136) of the module's supporting body (130). The modules are arranged so that their maximum light-intensity directions are largely the same. The block facets are configured to approximate a convex curved surface. The maximum light-intensity directions (158) of the block facets are thereby materially slanted relative to one another. Arranging the display system in this manner enables the light-processing efficiency to be very high. A motion simulator, such as a flight simulator, is formed by combining the screen with a reflective collimator (104).

  • Patent number: 9512984
    Abstract: A replacement lamp for an airport runway sign. Light is produced by a linear array of white-light LEDs. A cylindrical lens is mounted longitudinally adjacent to the LEDs, and collects a central portion of the light emitted from the LEDs. A pair of inclined surfaces extend from the lateral edges of the LEDs to respective lateral edges of the cylindrical lens. The inclined surfaces have a rough surface texture and reflect light diffusely. The inclined surfaces collect a peripheral portion of the light emitted from the LEDs, and direct the reflected light toward the cylindrical lens. The LEDs, cylindrical lens and inclined surfaces are all mechanically supported by a heat sink. The replacement lamp is placed into a runway sign near its top or bottom edge, and illuminates both viewing surfaces of the runway sign simultaneously without a diffuser.
