Abstract
Improved apparatus for lighting, characterized by comprising truncated conical parts with a central through hole, whose frustoconical parts have their side surface toothed, between whose teeth, the end of radial arms is housed, for which, this end, ends in a way of head with the outer side in inclined form, having a cup likewise frustoconical, which is coupled to the tooth, and press the radial arms against the bottom of the recesses between the teeth, supporting the internal lateral surface of conical shape, on the inclined side of the head constituting the end of these arms, obtaining this pressure, by screwing a nut on the central chalk of the apparatus, which, resting on the channel, displacing all the radial arms, towards the center of the apparatus, so that by decreasing its theoretical diameter, all the pieces that form it fit together.
