The present invention provides for a lamp assembly which can be utilized in overhead signaling or lighting applications such as in traffic signal lamps or illuminated overhead road signs. The assembly includes a lens that optimizes and redirects light in a desirable direction in order to meet certain regulations. The lens of the present invention is designed to power portions of light emitted from an LED while allowing other portions to pass through the lens unaided. The lens of the present invention works in combination with specific LEDs to efficiently redirect light emitted from the LEDs. The assembly includes a circuit board including a plurality of rows of LEDs and the lens, which has an exterior surface and an interior surface. The interior surface of the lens comprises a plurality of rows of horizontal bands with a single band being associated with a row of the LEDs. Each of the bands has an upper region and a lower region used to redirect some light rays downward, allow some rays to travel uninterrupted and redirect some light horizontally.

Led illuminated lamp assembly

A surface mounted LED package according to the invention includes a housing having a generally rectangular parallelepipedal shape. A lens is received in a passageway in the housing and has a radiating surface extending beyond the surface of the housing, a rear light collecting surface, and a cavity to receive an LED. An LED is received in the lens cavity. Conductive spring clips engage the housing and make electrical contact with the LED.
