ABSTRACT:
Disclosed is a light fixture assembly which includes a standard socket for receiving an electric light bulb and a sleeve with a cylindrical opening, the sleeve being rigidly mounted around the socket in order to conceal and protect it while at the same time supporting a lamp shade. The shade comprises a fixation collar sized to facilitate its insertion into the cylindrical opening of the sleeve. This basic structure which is known per se is improved in that the shade is rigidly fixed to the sleeve via the fixation collar by force-fitting male and female elements disposed respectively on the interior surface of the sleeve and the exterior surface of the fixation collar in order that the female elements receive the male elements when the lamp shade connection ring is forceably inserted into the cylindrical opening. Each female element is preferably disposed at the end of a circumferential groove opening at the leading edge of the ring to receive and guide the corresponding male element. This assembly is particularly advantageous because it is at once extremely simple and very efficient in resisting vibrations, thereby allowing the assembly to be used on a fixture encountering small movements such as for example, a ceiling ventilator. In addition, this assembly allows the lamp shade to be quickly and easily replaced by another which attunes better with the surrounding decor.
