Abstract

The present invention provides for a lamp assembly that includes a lens (1) that optimizes and redirects light in a desirable direction in order to meet certain regulations. The lens of the present invention works in combination with specific LEDs (11) to efficiently redirect light emitted from the LEDs (11). The assembly includes a circuit board (9) including a plurality of rows of LEDs (11) and a lens (1), which has an exterior surface (7) and an interior surface (5). The interior surface (5) of the lens (1) comprises a plurality of rows of horizontal bands (3) with a single band being associated with a row of LEDs (11). Each of the bands (3) has an upper region (3a) and a lower region (3b) used to redirect some light rays downward, allow some rays to travel uninterrupted and redirect some light horizontally.
