  • Patent number: 8511849
    Abstract: A method for bending a perimeter light and a perimeter light for illuminating curved surfaces. One embodiment of a bending method according to the present invention comprises heating a perimeter light to make it pliable. A radius tool is then provided having a curved surface with a shape and radius for the desired bend in the perimeter light. The heated perimeter light is mounted to the radius tool curved surface. The perimeter light is then cooled and removed from the radius tool. One embodiment of a bent elongated perimeter light according to the present invention comprises an array of light sources and an elongated tube bent to match a curve or shape. The array of light sources is disposed within the tube and the tube transmits and disperses the light from the array to give the appearance that said array of light sources is a continuous light source. The array of light sources is cuttable at intervals to shorten the array while allowing the remaining light sources in the array to emit light.

  • Patent number: 8388180
    Abstract: In a variable shaped lamp shade of an LED lamp, the lamp shade is made of a translucent material matched with an LED lamp strip and a lamp holder and includes at least one strip-shaped optical refraction unit having an external refractive surface, an internal refractive surface corresponding to the external refractive surface, and an assembling structure for matching the lamp holder. The external refractive surface or internal refractive surface is a curved surface without an inflection point and the curved surface has a constant or gradually changing curvature; and a non-curved surface is formed on the other side. The variable shaped lamp overcomes the problems of conventional LED lamp strips having a low illumination and a non-uniform illumination caused by a direct projection or an installation of a conventional lamp shade, and a low light utility caused by a too-large illumination range.

  • Patent number: 8297794
    Abstract: The method is for directing light in a fluorescent piece. Sequentially placed wedge-shaped pieces form a multiple-piece arrangement. Each piece has a base surface and a sloping top surface so that there is a first pointed end at one end and a short end surface at a second opposite end thereof. The pieces are exposed to light beams that hit fluorescent particles disposed inside the pieces. As a result, the particles emit a fluorescent light that are reflected off the inner surfaces of each piece as long as the light beams do not hit the surface at a perpendicular angle. The light beams are directed to penetrate the short end of each piece to form a continuous illuminated surface.
