A luminaire (10) has first light source (30) which provides light into a light mixing chamber (20) such that un-collimated light reaches the light output face (26) of the light mixing chamber (20), and a second light source (32) which provides collimated light to the light output face (26). The luminaire (10) can thus produce a diffuse flat light output and/or a directed partially collimated light output for example for task lighting.

A light source device includes: a light source having an upper surface including a light-emitting surface, the light source comprising a plurality of light-emitting parts arranged in a two-dimensional array; a lens located above and spaced apart from the light-emitting surface of the light source, wherein the lens comprises an optically functional part, and a flange part located along an outer periphery of the optically functional part; and a support part formed of a light-shielding material and configured to support at least the flange part of the lens. A surface area of a first surface of the optically functional part is greater than a surface area of a second surface of the optically functional part. The flange part defines at least one first recess in a surface located at a same side as the second surface.

A variety of light-emitting devices for general illumination utilizing solid state light sources (e.g., light emitting diodes) are disclosed. In general, the devices include a scattering element in combination with an extractor element. The scattering element, which may include elastic and/or inelastic scattering centers, is spaced apart from the light source element. Opposite sides of the scattering element have asymmetric optical interfaces, there being a larger refractive index mismatch at the interface facing the light emitting element than the interface between the scattering element and the extractor element. Such a structure favors forward scattering of light from the scattering element. In other words, the system favors scattering out of the scattering element into the extractor element over backscattering light towards the light source element. The extractor element, in turn, is sized and shaped to reduce reflection of light exiting the light-emitting device at the devices interface with the ambient environment.
