at least one adjustable arm (9) having a first end (11) pivoted on said perimetral edge (5) to move by means of its rotation about said first end (11) from a lowered rested position wherein it is parallel to said worktop (2) to an operative position raised with respect of said worktop (2) and a second end (12) provided with a light source (10) suitable for directing a light beam towards said top working surface (4) when said adjustable arm (9) is in said raised position; wherein said at least one adjustable arm (9) is adapted to be brought into a plurality of raised operative positions to vary the direction of origin of the light beam emitted by said light source (10); wherein two adjustable arms (9) are provided with respective light sources (10) and hinged on said perimetral edge (5) in symmetrical positions with respect to a middle vertical plane of symmetry of said worktop (2). ### Claim 2 (depends on 1) Desk as claimed in claim 1, characterized in that said at least one adjustable arm (9) is designed to be flush with said top working surface (4) when it is in said lowered position. ### Claim 3 (depends on 1) Desk as claimed in claim 1, characterized in that said at least one adjustable arm (9) is complementarily shaped with respect to a portion of said perimetral edge (5). ### Claim 4 (depends on 3) Desk as claimed in claim 3, characterized in that said perimetral edge (5) comprises a front edge (6) provided with an opening for access to a drawer or compartment (7) and at least one side edge, said at least one adjustable arm (9) being hinged at said first end (11) to said side edge to keep said front edge (6) always accessible both in said lowered position and in any of said raised positions. ### Claim 5 (depends on 1) Desk as claimed in claim 1, characterized in that said light sources (10) comprise a plurality of light spots suitable for emitting respective light beams to illuminate said top working surface (4) substantially in a complete manner. ### Claim 6 (depends on 1) Desk as claimed in claim 1, characterized in that the desk comprises a motor unit (13) associated with said adjustable arms (9) to promote the controlled passage thereof between the respective lowered and raised positions, in a manner independent or synchronized with each other. ### Claim 7 (depends on 6) Desk as claimed in claim 6, characterized in that said motor unit comprises for each of said adjustable arms (9) an electric motor arranged at the lower face (14) of said worktop (2). ### Claim 8 (depends on 1) Desk as claimed in claim 1, characterized in that it comprises an electric power unit (15) of said one or more light sources (10). ### Claim 9 (depends on 8) Desk as claimed in claim 8, characterized in that said electrical power unit (15) comprises one or more batteries or accumulators (16) arranged on the lower face (14) of said worktop (2), and/or a cable (17) for connection to an electrical network.
