Abstract:
1. A high intensity light emitting diode floodlight, the floodlight having a designed direction of output, comprising: a plurality of light emitting diodes; a plurality of optical elements; a plurality of blades comprising opposing sides having normal vectors perpendicular to the designed direction of output and the normal vectors are approximately parallel to each other, each of the blades having a free end and a fixed end; and a heat sink thermally coupled to the fixed end of each of the blades, configured to dissipate heat away from the light emitting diodes, wherein each of the sides receives a plurality of the light emitting diodes and optical elements, wherein a single optical element is mounted adjacent to a single light emitting diode in order to reflect light produced by the light emitting diode in the designed direction of output.
