  • Patent number: 9163802
    Abstract: The present subject matter utilizes solid state sources to pump remote phosphors positioned within lighting fixtures to facilitate visible light illumination application in a region or area to be inhabited by a person. One or more phosphors are remotely positioned in a chamber of a lightguide element, which in some examples, substantially fills an optical volume of the fixture. The chamber includes a solid liquid or gas material for bearing the one or more phosphors. Multiple phosphors, for example, may together produce light in the fixture output that is at least substantially white and has a color rendering index (CRI) of 75 or higher.

  • Patent number: 9109769
    Abstract: Systems and methods for lighting body panels of automobiles to facilitate repair of the body panels, where one embodiment is a portable lighting apparatus that includes a light board, a base and an extension member that connects the light board to the base. The light board is supported by the extension member, which is supported by the base. A battery in the base provides power through conductors in the extension member to light sources in the light board. A slip ring in the extension member couples the conductors together so that they can rotate, thereby allowing the light board to rotate with respect to the base, without twisting the conductors. A suction cup mount on the base enables the base to be secured to an automobile body panel, and the extension member allows the light board to be positioned as desired.

  • Patent number: 8939623
    Abstract: Disclosed is a projection lens that is disposed in front of a first semiconductor light emitting device and configured to irradiate light incident from the rear side to the front side. A first reflector reflects a part of the light emitted from the first semiconductor light emitting device to converge on the rear side of the projection lens. A light guide member is disposed across the front side of the projection lens and configured to emit the light incident from the second semiconductor light emitting device to a predetermined direction. A second reflector reflects a part of the light reflected by the first reflector toward the projection lens. The light reflected by the second reflector to be incident on the projection lens is emitted from the projection to avoid the light guide member.

  • Patent number: 7874712
    Abstract: A suspended light fixture includes a housing having first and second members configured to engage one another in a closed position and disengage from one another in an open position. For example, one member can include a cover, and the other member can include a housing body. The housing contains at least one internal component coupled to one of the members. The first member is configured to receive at least one cable. At least one cable gripper is coupled to the first member. Each cable gripper is slidable along a corresponding cable in a first direction and configured to only allow movement of the cable gripper in a second, opposite direction, upon operation of a mechanism. Movement of the cable grippers in the first direction causes corresponding movement of the first member, towards the open position. In the open position, the internal components are accessible for maintenance or another activity.
