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.

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.

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.
