    摘要： Various techniques are described herein for combining two or more LEDs in a single reflective cavity for a rear lamp in an automobile. The LEDs may be two or more different colors for performing different functions, such as a stop light, a turn signal, and a tail light. In one embodiment, the LEDs have side emitting lenses and are coaxially aligned in a parabolic reflector. The LEDs may be mounted facing each other or mounted in the same direction, or a combination of both. The LEDs may share a common heat sink. A second reflector may be positioned inside a larger reflector, where a first LED is mounted near the focal point of the larger reflector, and a second LED is mounted near the focal point of the inner reflector. Additional LEDs may also be mounted in either reflector and separately controlled.

    摘要： Lenses for LEDs are described that efficiently create a substantially uniform light emission across a surface of a backlight box. The backlight may illuminate an LCD. A wide-emitting lens refracts light emitted by an LED die to cause a peak intensity to occur within 35-65 degrees off the die's center axis, normal to the die's top surface, and an intensity along the center axis to be between 40% and 90% of the peak intensity. The lens is concave over the die and has smooth edges that transition into the lens sidewalls. The direct emissions of the lenses from a plurality of LEDs arranged on a base surface in a backlight box combine together to uniformly illuminate a light output surface of the backlight box.
