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.

La lentille de la présente invention coopère avec des DELs spécifiques (11) pour réorienter efficacement la lumière qu'elles (11) émettent. L'ensemble comprend une plaquette à circuit imprimé (9), comprenant une pluralité de rangées de DELs (11) et une lentille (1) présentant une surface externe (7) et une surface interne (5). La surface interne (5) de la lentille (1) comprend une pluralité de rangées de bandes horizontales (3) avec une seule bande associée à une rangée de DELs (11). Chacune des bandes (3) présente une région supérieure (3a) et une région inférieure (3b) servant à réorienter certains rayons lumineux vers le bas, pour permettre à certains rayons de passer sans interruption et de réorienter une partie de la lumière horizontalement.
