  • Patent number: 7448770
    Abstract: Disclosed is a method and apparatus for providing a solid state light emitter and driving circuitry integrated into a component module that will retrofit common incandescent light bulb applications. The disclosed embodiment is directed to the retrofitting of small flashlights using miniature bulbs, such as the Mini MagliteĀ®. Because the emitter and driving circuitry cannot readily fit within the envelope of the bulb being replaced, the volume occupied by the module needs to be acquired from within the flashlight's interior, such as from part of the volume occupied by the reflector. In that case, the invention includes a replacement reflector supplied with the module. The invention provides that no original functionality of the flashlight is sacrificed. Consideration is also given to the conduction of heat from the light emitter and module.

  • Patent number: 7441916
    Abstract: A reflecting plate in form of dual half-ellipses comprises a first ellipse having a first focal point and a second focal point, and a second ellipse having a first focal point and a second focal point. The first ellipse and the second ellipse commonly share the first focal point. A cross-section of the reflecting plate is designed in such a form that the dual half-ellipses are aligned with each other, and that contours of the first ellipse and the second ellipse are divided by a straight line, which includes the commonly shared first focal point and the other focal points. The reflecting plate encloses the line light source by the dual half-ellipses and reflects a light from the line light source toward the diffusion plate arranged above by specular reflection and by diffused reflection. As a result, uneven brightness is eliminated at the boundary of the reflecting plate designed in form of dual half-ellipses.
