  • Patent number: 7976184
    Abstract: An illumination system includes an illumination source such as an array of LED's over which is provided a diffuser. The illumination source provides light which, because of light refraction, radiates generally uniformly from edge to edge of the diffuser. The diffuser may be a planar flat piece of may include a hollow, cup like structure formed by a frame with a cover. The illumination system may be scaled up to provide multiple such illumination devices side by side to provide a greater area or strength of illumination. Multiple systems may utilize multiple diffusers or a single diffuser covering multiple illumination sources. The illumination source may be mounted to a backplate or heatsink which is larger than the illumination source to facilitate the addition of further electronic circuitry and or mounting capabilities.
