Beschreibung
Zusammenfassung:	The invention concerns a lighting device (100,100′), wherein the light source comprises a plurality of LEDs (110) and a reflecting body (120) for the housing of the source and the conveying of the light according to a pre-defined exit angle of the light beam, characterised in that: the internal surface (125) of said reflecting body (120) has a cross-section, with respect to its principal extension direction, that comprises at least two portions (121, 121′) of a parabola which are symmetrical with respect to the axis of the same parabola; substantially in the focus of said cross-section is housed a plurality of LED (110); the LEDs (110) of said plurality of LEDs being connected to a first side of a laminar strip (130), on the second side (132) of the laminar strip, side facing in the direction opposite to said reflecting body, being connected a dissipative band (140) for dissipating heat generated by the LED (110).
