The invention provides a luminaire comprising an optical element configured to spread light uniformly across a full visible face of the luminaire. The optical element comprises a central region and an outer peripheral region, each configured to receive light emitted by a light source arrangement and to direct this light out through a respective region of the light exit area of the luminaire. The central region receives light through a central transmissive surface portion which partially bounds it across its top. A further reflective tapered portion of the central region acts to reflect light incident at either of its two opposing sides, and provides a mixing function both within the central region of the optical element and within an inner compartment of the luminaire which extends between the optical element and the housing.

A directional illumination apparatus comprises an array of micro-LEDs that may be organic LEDs (OLEDs) or inorganic LEDs and an aligned solid catadioptric micro-optic array arranged to provide a water vapour and oxygen barrier for the micro-LEDs as well as reduced sensitivity to thermal and pressure variations. The shape of the interfaces of the solid catadioptric micro-optic array is arranged to provide total internal reflection for light from the aligned micro-LEDs using known transparent materials. A thin and efficient illumination apparatus may be used for collimated illumination in environmental lighting, display backlighting or direct display.
