Definitions

  • the present invention refers to a lighting lamp according to the preamble of claim 1.
  • lamps are known in various embodiments. Besides the tubular lighting lamps, lamps with incandescence or halogen bulbs have the common characteristic of comprising a diffuser body, lighting means housed in said diffuser body, hanging means or a supporting base, as well as the required circuital components.
  • the diffuser body may be provided transparent, or opaque, for example bell-shaped, delimiting the outgoing light beam, wherein the lamp is freely visible.
  • Such lamps may have hanging means, for example in form of a chain or tube which can be hooked to a hook fixed onto the ceiling or, for example in case of floor lamps or desk lamps they may have a base, wherein interposed between said base and diffuser body are supporting elements, for example in form of a tube, for example curved (in case of floor lamps or desk lamps) or several rods or tubes articulated to each other like arms, with springs or counterweights interposed, for the desired positioning of the diffuser body (for example in the case of desk lamps).
  • hanging means for example in form of a chain or tube which can be hooked to a hook fixed onto the ceiling or, for example in case of floor lamps or desk lamps they may have a base, wherein interposed between said base and diffuser body are supporting elements, for example in form of a tube, for example curved (in case of floor lamps or desk lamps) or several rods or tubes articulated to each other like arms, with springs or counterweights interposed, for the desired positioning of the diffuser body (for example in the case of desk lamps
  • a variation of the intensity of the luminous flux may occur, with halogen lamps, generally with two different voltages, for example of 25 and 50 W, using a transformer, generally housed in the base.
  • the intensity of the light flux may also be varied through a converter or trimmer.
  • lamps, headlights and downlights with lighting means in form of incandescence, halogen, fluorescent and low consumption lamps reveal practical limits.
  • lamps with a light dimmer practically absorb the same amount of power regardless of the set variation.
  • a variation of the position of the emitted light beam requires an articulated support for the diffuser body and, as a consequence, higher reproduction costs with respect to a fixed diffuser body.
  • the diffuser body generally has only one large opening for the outgoing of the light. Furthermore, providing for a plurality of exposed lamps arranged spaced on a strip-like support - such solution being definitely suitable for industrial lighting, shops, shop-windows and the like, but less suitable for household lighting where less strong and preferably more diffused lighting is required - for the diffusion of light along a relevant length is also known.
  • the production of the openings for the outgoing of the light may be provided in a simple, controlled and quick manner through laser beam cutting.
  • the lamps may be assembled in a simple, automatable and quick manner given that the lamp is made up of a limited number of components.
  • advantageously used as lighting means are LEDs, which currently have good lighting performance, occupy little space and are easily available, for example, on a tape-like support, for example a fabric, which in turn can be easily fixed on a stiff strip-like support, for example made of metal or synthetic material, which can be easily inserted or fixed in the tubular diffuser body.
  • Said stiff support may divide, for example diametrically, the tubular body into two chambers, in which the LEDs are arranged towards the chamber with the openings for the outgoing of the light.
  • LEDs emitting light of respectively different colours.
  • the use of LEDs also allows eliminating the prior art transformers and allows power supply by means of conventional AC adapters which can be inserted directly into the power supply sockets.
  • the diffuser body may be fixed directly to a base, in which intermediate supports - for floor lamps - and articulated arms, springs and so and so forth - for desk lamps - may be eliminated.
  • the provided screening diaphragm protects the diffuser body against penetration of dust, insects and dirt and facilitates the cleaning of the diffuser body. It may also be tubular, for example made of synthetic and transparent material, with a longitudinal slot which allows, when closed, an easy insertion thereof into the diffuser body and, when released, a self-locking positioning thereof into the diffuser body. This also facilitates the assembly of the lamp.
  • the lighting lamp according to the invention is indicated in its entirety with 1 and, according to a first aspect of the proposed disclosure, it has a tubular diffuser body 2 which does not require any supporting element but it can be directly fixed to a base 3, shaped at will.
  • the opening for the outgoing of the light is not provided for solely at the opening 4 of the diffuser body opposite to the base 3, such opening 4 possibly being provided for closable by a cover element, for example removable, not illustrated, but it may be divided into a plurality of openings 5, shaped at will, for example rectangular, circular, and so on and so forth, which are distributed along the diffuser body 2 at will.
  • said openings 5 are provided for on and along half of the surface of the diffuser body 2, which may have a circular or polygonal cross section at will. This allows obtaining a stabilised light emission at will, depending on the desired lighting results and effects.
  • the openings 5 are easily obtainable through laser cutting in the diffuser body 2, preferably made of metal, for example steel, light alloy and so on and so forth.
  • LEDs - monochrome or coloured at which are provided for in a number suitable for the geometric dimensions of the diffuser body 2 and the light to be emitted - are preferably provided for as lighting means 6.
  • Said LEDs 6 may, for example, be fixed to a flexible tape-like support 7, for example consisting of a fabric, in turn fixed to a stiff strip-like supporting element 8 inserted into the diffuser body 2, for example as a diametral diaphragm and forming two internal chambers 9 and 10, as illustrated in figure 2 , the chamber 10 in the illustrated example representing a blind chamber.
  • the LEDs 6 are arranged in the chamber 9, in whose semi-surface of the diffuser body 2 the openings 5 are provided.
  • Said diaphragm 11 may be made of stiff transparent synthetic material, for straight diffusers, figure 1 , or flexible synthetic material, for curved diffusers, figure 3 .
  • the LEDs 6 may be divided - in terms of circuit - into two or more groups, inserted through known connection means, like switches or the like, not illustrated, supported in the base 3, or controllable by a remote control, also not illustrated.
