A lighting device comprises a carrier having a radially outwardly facing mounting surface and an inner cavity radially within the outer mounting surface. Solid state lighting devices are mounted on the outer mounting surface and a driver is housed in the inner cavity. A ring shaped optical unit defines a light output region of the lighting device and is mounted around the carrier. An outer housing reflects light from the arrangement of solid state lighting devices to the ring shaped optical unit. This provides a compact arrangement, in which the driver, the heat sink (implemented by the carrier), and the solid state lighting arrangement are essentially in a plane. This is possible by providing a ring of light sources facing radially outwardly, with the driver mounted radially inside the ring. The radial light output is converted to a light output with a desired direction and beam shape by the optical unit.
