Abstract

THE PRESENT INVENTION CONCERNS AN IMPROVED LAMP. THE LAMP IS CHARACTERIZED IN THAT IT CONSISTS OF A CORE 4 CONSTITUTED BY A TUBULAR ELEMENT CARRYING INSIDE A CAP 3 AXIALLY MOVABLE AND CARRIING IN ITS FIREPLACE OF A LIGHT GENERATING ELEMENT 1, THE EMISSION OF WHICH IS CONCENTRATED ON A ADJUSTABLE SENSOR 5 ACTING AS THE PLUG AND CONTAINING ONE OF THE ENDS OF THE TUBULAR CORE. THE PRESENT INVENTION FINDS AN APPLICATION IN THE FIELD OF LIGHTING.

Description

The present invention relates to a new lamp

  perfected, of the type ceiling lamp comprising a

  central core of o branch off multiple arms and by-

  which a single light generating element using fiber optic transmission allows the distribution of the light waves generated in the single focus of

  light to all dividing elements or arms.

  For this purpose, the lamp is characterized in that the core is constituted by a tubular element

  inside a cap that can be dismounted axially and

  in its focus of a light-generating element, whose emission is concentrated on an adjustable sensor

  acting as a stopper and closing one of the ex-

  tremities of the tubular core, one end of the

  a plurality of light-conducting optical fibers converging at one point of the sensor and the second end of said optical fibers traveling multiple arms of irregular configuration being the emission point of the

corresponding arm.

  The actual character of the lamp according to

  vention makes it perform well and is eco-friendly.

  The invention will be better understood, and other purposes,

  characteristics, details and advantages of it

  will become clearer in the course of the description
