ABSTRACT:
A lighting device, comprising a light engine housing, a light engine comprising one or more solid state light emitters, a diffuser and an energy forwarding element which receives AC voltage and supplies power to the light engine. The light engine housing comprises an electrical connection region which is engageable with an electricity supply device. The light engine housing comprises a first compartment, in which the light engine is positioned and a second compartment. The light engine housing comprises a flange region. The first compartment has an opening which is covered by the diffuser. The lighting device can be mounted such the only elements which are visible from a room are the flange region, a front side of the diffuser and any portion of the first compartment which is between the opening and the open end of the light engine housing. The light engine housing can comprise heat-dissipating fins.
