1. A modular LED system comprising:
a frame comprising a first end, a second end, two sides, an upper portion, and a lower portion comprising a bottom, the frame defining a longitudinal axis extending from the first end to the second end; a plurality of light emitting diodes (LEDs) of at least two different colors for generating light within a color spectrum, said plurality of LEDs being mounted on or adjacent to a plate attached to the frame at the lower portion parallel to the longitudinal axis of the frame, wherein the plurality of LEDs is disposed in a grid on the plate and oriented to emit light in a direction perpendicular to the plate; one or more cooling ribs mounted onto the frame and positioned on a side of the plate opposite of the direction of light for cooling the LEDs with cooling medium; a processor for controlling an amount of electrical current supplied to the plurality of LEDs, so that a particular amount of current supplied thereto determines a color of light generated by the plurality of LEDs; and a flat translucent member having a plurality of translucent lenses, wherein the flat translucent member is positioned adjacent and parallel to the plate, each translucent lens corresponding to one LED of the plurality of LEDs, wherein the translucent lenses are constructed to control the diffusion angle of the light emitted from the LEDs to provide substantially uniform illumination of a surface; wherein the frame is provided with a tunnel for receiving a tube carrying power and optionally cooling medium for the LED system, and wherein all LEDs of the modular LED system are mounted at the bottom of the frame. |
