  • Patent number: 9016902
    Abstract: An illuminating building block with high light transmission includes a base, a top cover, a circuit board and at least one illuminating member. The illuminating building block uses electric connection members connected with the circuit board to electrically connect with the adjacent illuminating building block. Because the electric connection members are disposed by the top cover and a side wall, the electric connection members do not block the light emitted from the illuminating member. Thus, the illuminating building block is provided with the characteristic of high light transmission. Moreover, due to elasticity of the electric connection members, the electric connection members are pressed against the circuit board of the adjacent illuminating building block. Therefore, the electric connection between connected illuminating building blocks is more secure.

  • Patent number: 8430530
    Abstract: A luminaire, such as a lamp assembly or a floor lamp, umbrella, or planar or sheet-like like light emitting surface includes a conforming mechanism for selectively curving the light emitting surface. A convex profile will diffuse light while a concave profile will concentrate light, it being intended that the surface can be conformable up to a five inch (5?) radius of curvature in either direction. The light panel portions may be of the same color, or may be different colors that will result in different mixing of the light when made from different colors.

  • Publication number: 20130058091
    Abstract: Lighting module mounted onto a C-shaped rail having a bottom wall and electrical lines extending along the rail includes a light source board having a first face carrying one or more light radiation sources and a second face carrying electrical contacts. A channel-shaped housing envelops the board and has a web wall for emitting the light radiation and two opposed side walls each facing one of the longitudinal edges of the board. Each of a pair of opposed guide members extends along one of the longitudinal edges of the board facing a corresponding side wall of the housing. Each of the guide members and the corresponding side wall of the housing have complementary, mutually cooperating, ramp-like surfaces to retain the light source board within the housing. Elastic members urge the board away from the web wall of the housing, whereby the complementary ramp-like surfaces are elastically urged against each other.

  • Publication number: 20120224376
    Abstract: A structure and method for three-dimensional lighting using light active technology. The structure has one or more non-rigid, flexible, foldable double-faced sheet of light active material formed of two opposedly facing sheets of light active material arranged back-to-back and configured to emit light from front and back sides of the at least one double-faced sheet of light active material. A collapsible three-dimensional lighting structure is formed of the double-faced sheet(s) of light active material and a folding element. A power supply element provides power to the circuitry and is coupled to the plurality of lighting elements of the two opposedly facing sheets of light active material. A fastening element coupled to the double-faced sheets of light active material at a fastening point removably retains the three-dimensional form.

  • Publication number: 20120218761
    Abstract: A structure and method for three-dimensional lighting using light active technology. The structure has one or more sheets of light active material, with each sheet having lighting elements. The structure additionally has one or more folding elements along which the sheets of light active material are foldable to create a three-dimensional lighting structure having a center element located at a back side of the three-dimensional lighting structure. A power supply element can then be used to provide power to the lighting elements. A fastening element fastens together the sheets of light active material at fastening points to retain the three-dimensional lighting structure created by folding the one or more sheets of light active material. The three-dimensional lighting structure may be attached to a surface by attaching the center element directly to the surface or by attaching the center element to a substantially rigid backing that attaches to the surface.
