Lighting device (1), which comprises: a support body (6) which is delimited along a main extension direction (X) thereof by a first front edge (8) and by a first rear edge (9), and is provided with an outer surface (11), on which a plurality of LEDs (12) are mounted, and an inner surface (20), which defines an inner channel (7) of the support body (6) in which heat dissipation means are housed (16). The lighting device (1) also comprises: a reflecting body (25), which extends around the support body (6), having as generator a concave-shaped section turned towards the plurality of LEDs (12); a containment body (2) mounted outside the support body (6) and provided with a second front edge (30) substantially aligned with the first front edge (8) of the support body (6); a refraction plate (14) sealingly fixed in abutment against the first front edge (8) and against the second front edge (30), with the support body (6) and with the containment body (2) defining a sealed chamber (13) inside of which a plurality of LEDs (12) are mounted. In addition, the containment body (2) is provided with a second rear opening (17) and the refraction plate (14) is provided with a second front opening (18), whose openings (17) and (18) are aligned with the inner channel (7) of the support body (6) in order to allow the passage of a convective motion air flow through the inner channel (7) of the support body (6). |
