Patent Images
1. A lamp assembly comprising:
- a housing;
a printed circuit board;
a flexible support operatively connected to said printed circuit board;
at least one light emitting diode operatively connected to said flexible support; and
, a lens for transmitting light from said at least one light emitting diode, said lens having, a first optical element to scatter said light;
a second optical element to spread said light at an angle substantially 45°
to the left and right of the longitudinal axis of said at least one light emitting diode; and
, a third optical element to scatter said light.

Abstract
A tail/stop lamp assembly is disclosed that uses as a light source light emitting diodes, specifically SnapLEDs™. The tail/stop lamp assembly is composed of housing, a lens, and a SnapLED™ array. The lens is composed of six different optical units surrounded by Fresnel rings. The housing is of a very slim design. The combination of optics and housing is a stylish, sturdy and efficient tail/stop lamp assembly that complies with Society of Automotive Engineers (SAE) standards.
