  • Patent number: 8757840
    Abstract: A solid state directional lamp is disclosed. The lamp may include reflector defining a geometric curve, a reflective surface that is separable from the reflector defining the geometric curve, and a solid state light emitter. The solid state light emitter is positioned to direct light rays towards the reflector defining the geometric curve and to direct light rays towards the reflective surface. The reflective surface is configured to direct light rays from the solid state light emitter into the geometric curve. The geometric curve is configured to reflect light rays received from the solid state light emitter away from the lamp and is configured to reflect light rays received form the reflective surface away from the lamp.

  • Publication number: 20140078727
    Abstract: Light fixtures having light bar elements therein. In order to mimic the size and appearance of fluorescent bulbs in existing troffer-style and surface-mount fixtures, LEDs are may be arranged on light bars with integrated lenses to both diffuse the light and shape the output beam. One or more LEDs can be mounted, sometimes in clusters, along the length of a base of the light bar which can then be inserted into a fixture. An elongated lens is mounted to the base over the LEDs so that light emitted from the LEDs interacts with the lens before it escapes the fixture. These elongated lenses may be extruded from a diffusive material, for example, and can be shaped in various ways. For example, the lenses may be shaped to disperse more light to the sides, i.e., in a direction away from a normal axis that is perpendicular to the base.

  • Publication number: 20130176721
    Abstract: A light fixture with a textured reflector is disclosed. Embodiments of the present invention provide for a lighting system in which LEDs face, and the majority of light form the LED light source is incident on, a textured back reflector while producing minimal glare and minimal imaging of the light source. Such a reflector may be referred to as a retro-reflector. The reflector for the light fixture can be made from a relatively inexpensive material such as polycarbonate, which without texturing has a specular or semi-specular surface. Further, a diffuse white layer to provide color mixing or prevent glare and reflections is not needed. The textured reflector can be textured by way of an imprinted pattern or by roughening, and can be extruded. A prismatic texture may be used. The texturing can also be spatially varied.
