1. An apparatus comprising:
- a light guide including a rear portion, the rear portion including a first edge, a second edge, and a rear edge, the first edge meeting the rear edge at a first obtuse angle, and the second edge meeting the rear edge at a second obtuse angle; and
a plurality of light emitting diodes (LEDs) disposed on the first edge, the second edge, and the rear edge, the plurality of LEDs being arranged to produce an asymmetric light distribution pattern including a rear light emission and a forward light emission, the forward light emission having a greater peak intensity than the rear light emission.

Abstract
An apparatus is disclosed including a light guide and a plurality of light emitting diodes (LEDs). The light guide includes a rear portion including a first edge, a second edge, and a rear edge. The first edge meets the rear edge at a first obtuse angle, and the second edge meets the rear edge at a second obtuse angle. The plurality of light emitting diodes (LEDs) disposed on the first edge, the second edge, and the rear edge, and it is arranged to produce an asymmetric light distribution pattern including a rear light emission and a forward light emission having a greater peak intensity than the rear light emission.

8. An apparatus comprising:
-
a support structure; a housing coupled to the support structure; a light guide arranged in the housing, the light guide including a front portion comprising a uniform width throughout the front portion and a rear portion comprising a tapered width, the front portion including a front edge facing away from the support structure, and the rear portion including a rear edge facing towards the support structure; and a plurality of light emitting diodes (LEDs) mounted around a perimeter of the rear portion of the light guide to produce an asymmetric light distribution having at least a front emission that is directed away from the support structure and a rear emission that is directed towards the support structure, the front emission having a greater peak intensity than the rear emission. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
