Public lighting device with high energetic efficiency, including a casing (10, 12) for containing light sources, suitable to be connected with a support element, wherein the casing (10, 12) comprises a emitting device (13) of LEDs (24) light radiation; in particular, the emitting device (13) of light radiation comprises a base plate (17), made of conductive material, onto which a printed circuit board (20) of control and management of a series of power-emitting LEDs (24), a series of longitudinal mirrors or reflectors (21), which develop on planes parallel each other and substantially orthogonal to the plane towards which the light radiation is directed, and a series of transverse mirrors or reflectors (22), which develop on planes parallel each other and substantially orthogonal to the development plans of the longitudinal mirrors or reflectors (21), are mounted. In addition, finned heat dissipators (19), which are contained inside the containment casing (10, 12) and to which respective slits or cracks (11) made in the aforesaid containment casing (10, 12) correspond, are connected with the base plate (17).
