Abstract
An optical device may include a 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. 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 light turning element may be reflected by the end reflector and/or reflected from the second surface towards the first surface.
