  • Patent number: 6719442
    Abstract: The present invention provides an illumination device having a curved reflector for use with a light-emitting device. The illumination device includes conical or funnel shaped lens having a top section, a bottom section, an outer surface and an inner surface. The bottom section is enlarged and contains a hollow interior formed by the lens inner surface to receive a curved reflector. The top section contains a cavity adaptable to receive a light-emitting device so that when the light is illuminated, light is transmitted through the reflector lens. As light travels towards the bottom section, the curved reflector deflects light in the horizontal direction through the lens to prevent light from being absorbed by the base. The reflector lens outer and inner surfaces contain ridges to form a grid-like pattern to disperse light. This configuration provides an efficient means to transmit light to illuminate a surrounding area.
