Abstract:
A variety of light-emitting devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, a light-emitting device includes one or more light-emitting elements (LEEs) disposed on a base surface that are configured to emit light, a first optical element having a first surface spaced apart from the LEEs and positioned to receive light from the LEEs, a transparent second optical coupled to the first optical element, and a reflector element adjacent the second optical element arranged to reflect a portion of light output from the second optical element.
