Abstract: Disclosed is a system for the support and rotation of a reflector onto a body of a fluorescent luminary. The luminary body has first and second longitudinal ends along an axis. The rotatable reflector support system comprises an elongated reflector having first and second longitudinal ends. The reflector has first and second arch-shaped fittings proximate to the first and second reflector ends, respectively. First and second bases are mounted on the luminary body and are proximate to the first and second ends of the body, respectively. The side of each base faces the lamp, when the lamp is mounted in the luminary, and is shaped to engage a plurality of serial portions of an associated arch-shaped fitting in a manner allowing serial portions of the fitting, when manipulated, to slide along an arch-shaped path transverse to said axis and to hold the fitting in place when the fitting is not manipulated.

Abstract: Reflector (1) for light concentration and direction in fluorescent lamps with parabolic shape made of thin synthetic film with reflective surface and vertically positioned louvres (4) made of thin flexible and synthetic film through which the reflector (1) is fitted on the fluorescent lamps (3). In the centre of the louvres (4) there is an especially shaped opening (6) which adjusts to the diameter of the lamp (3), so that the lamp (3) can pass through the openings (6) of the louvres (4), retain the reflector (1) on the fluorescent lamp (3) and rotate some degrees in relation to the lamp (3) in order to concentrate the light towards the desired direction.
