Patent ID: 8459833

Claim:
A solid-state lighting unit comprising: a solid-state array housing defining an internal compartment and having at least one transparent lens for sealing the internal compartment; at least a first solid-state lighting circuit card assembly disposed within the solid-state array housing, the first circuit card assembly comprising a common circuit card and a respective plurality solid-state lighting elements, each solid-state light element comprising a light emitting diode (LED) and a respective optical lens having a respective optical characteristic, wherein each respective optical lens of the first solid-state lighting circuit card assembly has substantially the same optical characteristics and combine to produce a first illumination beam width; at least a second solid-state lighting circuit card assembly disposed within the solid-state array housing, the second circuit card assembly comprising a common circuit card and a respective plurality solid-state lighting elements, each solid-state light element comprising an LED and a respective optical lens having a respective optical characteristic, wherein each respective optical lens of the second solid-state lighting circuit card assembly has substantially the same optical characteristics and combine to produce a second illumination beam width, wherein the optical characteristic of each optical lens that produces the first illumination beam width of the first solid-state lighting circuit card assembly are different than the optical characteristic of each optical lens that produces a second illumination beam width of the second solid-state lighting circuit card assembly; a controller in electrical communication with each circuit card assembly of the plurality of solid-state lighting circuit card assemblies, the controller configured to independently control each circuit card assembly of the plurality of solid-state lighting circuit card assemblies, wherein at least two circuit card assemblies are in operation at the same time to produce a single solid-state lighting unit having multiple beam widths; and wherein a portion of each circuit card assembly meets at a central point.
