  • Patent number: 8292445
    Abstract: An optical system with an LED light source utilizes a base with an inverted conical shape to conduct light to a phosphor layer. The phosphor layer emits light from both upper and lower surfaces. The base and a substantially mirror image cap element facilitate efficient extraction of the phosphor-generated light from the optical system so that the output of the system is omni-directional light suitable for common lighting applications. The system is very efficient in that nearly all the light generated by the LED is transmitted to the phosphor layer, and nearly all the light emitted from the phosphor layer is output from the system.

    Abstract: A light source reflector includes a structure having three or more internal reflective surfaces defining a first light entry aperture and a second light exit aperture having an area that is greater than the area of the entry aperture. A single light source, or a plurality of uniformly distributed light sources, such as one or more LEDs, located proximal the entry aperture provides illumination, which impinges on the reflective surfaces from the entry aperture and is reflected off the surfaces to provides a substantially uniform illumination pattern exiting the exit aperture. The reflector advantageously allows for the use of a source (e.g., LED(s)) that is smaller than the targeted area of illumination and also avoids creating hot-spots as the reflector does not focus the light, but rather reflects mirror images of the source off of the reflective surfaces.

    Abstract: A retrofit kit is configured for a single or multiple tubular fluorescent lamp fixture. The original fixture being retrofitted may or may not have any reflectors. The kit includes a new improved reflector with double concave wings. The winged reflector preferably has a central arched, preferably trapezoidal portion which forms the lower cover of the fixture box. This central trapezoidal portion includes an access door to permit access to the ballast without the need to remove the winged reflector once it is installed. An arched, preferably trapezoidal socket bar is installed at each end of the fixture, to lower the position of the lamp with respect to the winged reflector surfaces, to enhance the light distribution in a downward direction while permitting enhanced up-lighting. The distal ends of the trapezoidal central portion of the reflector mate with the trapezoidal socket bars at opposite ends of the fixture.
