First Claim
1. A lighting device, comprising:
- a light engine housing;
means for generating light;
a diffuser; and
means for forwarding energy,said light engine housing comprising means for receiving AC voltage,said light engine housing comprising a first compartment and a second compartment,said light engine housing comprising a flange region which surrounds an open end of the light engine housing,said means for generating light within said first compartment of said light engine housing,said means for generating light comprising at least a first solid state light emitter,said means for forwarding energy within said second compartment of said light engine housing, said means for forwarding energy electrically connected to said means for receiving AC voltage, said means for forwarding energy electrically connected to said means for generating light, said means for forwarding energy comprising means for converting power of an AC voltage to DC current which, if supplied to said means for generating light, will cause said means for generating light to emit light,said first compartment having an opening which is covered by said diffuser, whereby at least a portion of light emitted by said first solid state light emitter which travels toward said opening will pass through said diffuser and then through said open end of said light engine housing to exit from said light engine housing,whereby if said lighting device is mounted in a hole in a structure such that at least a portion of a back side of said flange region is in contact with a region of said first side of said structure which surrounds said hole, and a remainder of said light engine housing is on an opposite side of said hole relative to said flange region, the only elements which would be visible within a field defined by an outer periphery of said flange region of said light engine housing from a vantage point which is in a region which is to said first side of said structure would be a front side of said flange region, a front side of said diffuser and any portion of said first compartment which is between said opening and said open end.

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.
