An improved LED signaling device employing a number of LEDs (5) arranged in a specific pattern. At least some of the LEDs (5) are received in a corresponding reflective cavity with an associated output angle. The LED signaling device also employs first (8) and second (9) lenses. The first lens (8) collects the light emitted by the LEDs (5) and disperses the light such that the second lens (9) is flooded. The second lens (9) collects the light dispersed by the first lens (8) and collimates the light. The type of LEDs (5) used, their specific pattern, the specific output angles of their corresponding reflective cavities, and the combination of the first and second lenses insure that the LED signaling device meets or exceeds the minimum luminous output intensity requirements and uniformity requirements. |
