Abstract (en)
[origin: EP1785667A2] An optical group with an adjustable light beam, comprising at least one lamp-holder device, at least two linear fluorescent lamps (10, 11) and a specular reflector (12); in the centre of the body (5) of the reflector (12) there are at least two curvilinear surfaces (6, 16-19), which, by varying their angular position, allow a variation in the form of the light emission of a lighting appliance, in relation to the various application requirements. Solutions such as those projected allow high efficiency levels of the lighting appliance to be maintained and obtained in particularly restricted volumes.
