Beschreibung
Zusammenfassung:	A lighting apparatus (1) with a variable light beam emission angle comprises a base body (4) extending along an axis (A) and a plurality of optical groups (5) mounted on the base body (4); each optical group (5) comprises a light source (6) and a dedicated optical system (7) associated with the light source (6); the optical groups (5) are provided with optical systems (7) configured so as to generate respective light beams having at least two different emission angles; a control system (20) acts on the light sources (6) to selectively turn on/turn off the light sources (6).
