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.

Abstract: A lamp comprising a light supported on a structure defining a path for the current supplying the bulb. The light comprises a housing and a support located between the structure and housing. The support consists of two arms hinged at the ends to the structure for enabling the housing to rotate about a first axis; and a pin perpendicular to the arms and supported in rotary manner inside the housing for enabling the housing to rotate in relation to the structure about a second axis perpendicular to the first. The support consists of two electrically insulated parts made of electrically conductive material.

Abstract: This articulated arm lamp comprises a base for supporting first and second mutually articulated arms; the second arm furthermore supports, at one end, a paraboloid which contains a light source; first and second arms are supported by a flexible element which is also simultaneously adapted to conduct electric current from the base to the light source.
