摘要： 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.

摘要： The present invention relates to a light emitting device comprising one or more LED light sources and one or more diffusely transmissive covers. The one or more diffusely transmissive covers extend over the one or more LED light sources to form one or more combinations of an LED light source and a diffusely transmissive cover. For each combination of an LED light source and a diffusely transmissive cover (i) the diffusely transmissive cover is dome-shaped with a vertical cross-section having a closed convex shape and a horizontal cross-section having a polygonal shape, (ii) the diffusely transmissive cover has a width (w) projected in a horizontal plane parallel to a bottom of the diffusely transmissive cover, (iii) the LED light source has a distance (d) to any neighboring LED light source. The width (w) and the distance (d) are perpendicular to each other, and the ratio of the width (w) and the distance (d) is constant.
