Abstract: An LED lighting lamp comprises an essentially annular perimetric frame positioned about an axis; a plurality of LEDs arranged along a radially inner perimetric edge of the frame and angularly spaced apart from one another about the axis; and a substantially flat and completely transparent light-guide plate, having two opposite faces substantially perpendicular to the axis and a radially outer perimetric edge facing the LEDs; at least one face of the light-guide plate is provided with an engraving pattern, formed by a plurality of notches shaped so as to extract light from the light-guide plate through said at least one face.

Abstract: A lighting device, in particular a standard lamp, having a stand, an upright, a shade, and lamp-holder means located inside the shade; the upright supporting the lamp-holder means and the shade; the shade having a through opening defined by opposite facing lateral walls, and through which the upright is inserted; and the lamp-holder means including a sleeve, to which the shade is connected integrally, and which is fitted to the upright to rotate about an axis of rotation perpendicular to the facing lateral walls of the opening in the shade, so that the shade may selectively assume at least three positions forming different angles with the upright.

Abstract: A polychrome lighting device, including at least one light source for each one of the three primary colors and elements for adjusting the light sources, the adjustment elements being adapted to independently control the adjustment of the luminous intensity of the light sources in order to combine the light beams emitted by the sources into a light beam having the desired shade of color, remote control elements being also provided for setting, storing, and retrieving desired luminous intensity values of the light sources and therefore desired light colors.
