Abstract:
1. An LED signaling device, comprising: a back plate; a circuit board coupled to said back plate, said circuit board having a first surface with a number of LEDs arranged in a pattern thereon; a reflector coupled to at least one of said back plate and said circuit board, said reflector having a number of reflective cavities each with an associated output angle, wherein at least some of said reflective cavities are arranged in said pattern and are structured to receive at least one of said LEDs therein; a first lens coupled to at least one of said back plate, said circuit board, and said reflector, said first lens structured to disperse light rays emitted by at least some of said LEDs, said first lens being located a first distance from said first surface; and a second lens, coupled to at least one of said back plate, said circuit board, said reflector, and said first lens, said second lens structured to receive said light rays dispersed by said first lens and to collimate said light rays dispersed by said first lens, said second lens being located a second distance from said first surface; wherein said pattern is arranged according to an x, y, z, coordinate system relative to a central axis of said LED signaling device and wherein said pattern includes: a first LED having an x-coordinate of about 16 mm, a y-coordinate of about 8 mm, and a z-coordinate of about 0 mm, said first LED being received within a first one of said reflective cavities with an associated output angle of about 12 degrees; a second LED having an x-coordinate of about −16 mm, a y-coordinate of about 8 mm, and a z-coordinate of about 0 mm, said second LED being received within a second one of said reflective cavities with an associated output angle of about 12 degrees; a third LED having an x-coordinate of about 42 mm, a y-coordinate of about 7 mm, and a z-coordinate of about 0 mm, said third LED being received within a third one of said reflective cavities with an associated output angle of about 15.5 degrees; a fourth LED having an x-coordinate of about −42 mm, a y-coordinate of about 7 mm, and a z-coordinate of about 0 mm, said fourth LED being received within a fourth one of said reflective cavities with an associated output angle of about 15.5 degrees; a fifth LED having an x-coordinate of about 25 mm, a y-coordinate of about 30 mm, and a z-coordinate of about 0 mm, said fifth LED being received within a fifth one of said reflective cavities with an associated output angle of about 30 degrees; a sixth LED having an x-coordinate of about −25 mm, a y-coordinate of about 30 mm, and a z-coordinate of about 0 mm, said sixth LED being received within a sixth one of said reflective cavities with an associated output angle of about 30 degrees; a seventh LED having an x-coordinate of about 30 mm, a y-coordinate of about −30 mm, and a z-coordinate of about 0 mm, said seventh LED being received within a seventh one of said reflective cavities with an associated output angle of about 50 degrees; and an eighth LED having an x-coordinate of about −30 mm, a y-coordinate of about −30 mm, and a z-coordinate of about 0 mm, said eighth LED being received within an eighth one of said reflective cavities with an associated output angle of about 50 degrees.
