Abstract
A lighting device comprises a support plate having first and second sides and a current supply attached to the first side; a structure for supporting the support plate at a distance from a surface of a room is provided, defining a laterally open space between the support plate and the surface; a leg having first and second ends, the first end penetrating the plate and protruding from the second side; a first socket is attached to the second end for attaching and electrically connecting a light bulb, and a second socket is disposed on the first side in the space for attaching and electrically connecting a further light bulb for indirectly lighting the room. The plate may be spaced from the surface by a cast resin body into which the current supply is embedded, or by a holder in the form of a multi-legged holder star.
