Abstract: An optical device comprising may include a wedge-shaped light turning element. The optical device can include a first surface that is parallel to a horizontal axis and a second surface opposite to the first surface that is inclined with respect to the horizontal axis by a wedge angle. The optical device may include a light module that includes a plurality of light emitters. The light module can be configured to combine light for the plurality of emitters. The optical device can further include a light input surface that is between the first and the second surfaces and is disposed with respect to the light module to receive light emitted from the plurality of emitters. The optical device may include an end reflector that is disposed on a side opposite the light input surface. The second surface may be inclined such that a height of the light input surface is less than a height of the side opposite the light input surface. The light coupled into the wedge-shaped light turning element may be reflected by the end reflector and/or reflected from the second surface towards the first surface.

Abstract: An optical device may include a wedge-shaped light turning element, a first surface that is parallel to a horizontal axis, a second surface opposite to the first surface that is inclined with respect to the horizontal axis by a wedge angle, and a light module including light emitters. The light module can be configured to combine light emitted by the emitters. The optical device can further include a light input surface that is between the first and the second surfaces and disposed with respect to the light module to receive light emitted from the emitters. The optical device may include an end reflector disposed on a side opposite the light input surface. Light coupled into the light turning element may be reflected by the end reflector and/or reflected from the second surface towards the first surface.
