Definitions

  • the present invention relates to a device for receiving at least one light source.
  • the invention relates more particularly to a device for receiving at least one light tube, in particular a fluorescent tube.
  • Fluorescent tubes are generally cylindrical objects, elongated and hollow for example glass. These tubes contain one or more gases such as helium, carbon dioxide, neon, argon, mercury ... Moreover, these tubes comprise, on the one hand, on their internal walls a powder fluorescent and, on the other hand, at each of their longitudinal ends a pin base comprising for example two pins. Fluorescent powders are generally composed of silicates, aluminates and / or halophosphates, etc. The pins are capable of allowing an electric current to enter the interior of the tube so as to electronically excite the gas atoms contained in the tube. Indeed, when the gas atoms de-energize electronically, they emit ultraviolet (UV) radiation. The fluorescent powder then absorbs ultraviolet radiation and re-emits light radiation in the visible spectrum, i.e. in a wavelength range of about 380 nm to 780 nm.
  • UV ultraviolet
  • Fluorescent tubes need to be installed with electronic and / or electrical control components that allow the ignition of the tube (for example a choke) and / or the regulation of the voltage, the current (for example a ballast), the frequency of the current ...
  • These tubes are generally installed in a support element comprising, on the one hand, sockets for connecting the tube to the electric circuit and, on the other hand, electronic and / or electrical current control components and / or the electric tension.
  • the light tube can be installed in a protective body to limit the risk of damage to the tube for example by water, shocks ...
  • Document is known DE3204644 a device for receiving a monobloc light tube which, however, has a relatively complicated form to manufacture. Moreover, this device is intended to be fixed to a ceiling and is therefore not flexible in its installation possibilities.
  • the invention relates to a device for receiving at least one light tube according to claim 1.
  • the protective body is made in one piece (or monoblock) allows a simpler design and manufacture. In addition, this allows the protective body to be sealed over its entire length.
  • the separating means makes it possible to physically separate the electronic and / or electrical component or components of the control system from the light source. Indeed, it is preferable to prevent the electronic and / or electrical control and power supply system (ballast %) from coming into contact with the light source during installation, handling, transport and / or the operation of the device to limit any risk of deterioration of the aforementioned elements.
  • portion able to let the light pass may be more or less extended depending on the shape of the desired light emission cone.
  • end caps each fixed on a base makes it possible to install the device on any type of support (ex: wall).
  • the ability to rotate the tips about the longitudinal axis of the protective body allows to vary the orientation of the device (thus the direction of light emitted) compared to the bases that remain in a fixed position on the support of installation (wall .%) and thus to adapt it to its installation environment (ex: constraints of size).
  • the symmetrical configuration of the protective body and its end pieces is advantageous in terms of manufacture.
  • substantially elongated shape for the protective body, a shape that is longer than wide and is particularly suitable for receiving light sources having a tube shape.
  • the protective body is made by extrusion (or by coextrusion).
  • This method facilitates the design and manufacture of the protective body, because the part does not require additional machining operations.
  • it is inexpensive and offers great versatility, on the one hand, in the materials used for the manufacture of the protective body and, on the other hand, in the possible forms of said body.
  • the protective body may be made of a material based on polymers, in particular polycarbonate.
  • the separation means comprises at least one partition.
  • the separation means is part of an envelope which is adapted to be inserted into said at least one cavity of said protective body and which delimits (internally) the second compartment.
  • the casing makes it possible to stiffen the protective body and to give the protective body better mechanical strength with respect to the stresses that could be applied to it.
  • the envelope takes for example the form of a cross-sectional conduit (for example square, rectangular, circular, oval ...) adapted to that of the protective body and / or its or its cavities.
  • the envelope is made by extrusion (or by coextrusion).
  • the casing may be made of a material based on polymers, in particular polycarbonate.
  • the envelope (example: internal conduit to the cavity or cavities) is opaque.
  • the opacity of the envelope makes it possible to conceal the components of the electronic and / or electrical control system of the light tube (electrical cables, power supply, etc.) which is housed in the protective body (when the protective body is transparent or translucent).
  • the receiving device comprises a light reflecting means interposed between the separating means and the first compartment.
  • This arrangement makes it possible to maximize, in a desired direction, the light power emitted by the light source. This therefore reduces the power of the light source needed to illuminate the desired location. In addition, this reduces the energy consumption of the light source.
  • the separating means integrates the light reflector means.
  • the protective body comprises at least one holding element in the (static) position of the separating means.
  • the holding or immobilizing element prevents the separation means from coming into contact with the light tube and damaging it.
  • said at least one holding element comprises, inside said at least one cavity, at least two projections substantially opposite one another which are arranged on either side of the means of separation between the latter and the protective body.
  • the portion of the protective body capable of allowing the light to pass comprises at least one means for diffusing the light.
  • Said at least one light diffusion means makes it possible to diffuse the light emitted by the light source contained in the body of protection. More particularly, this makes it possible to homogenize the distribution in space of the light power emitted by the light source.
  • said at least one light scattering means is a set of striations, for example parallel to each other.
  • Streaks for example obtained by extrusion, improve the rigidity of the protective body.
  • the protective body has a cross section substantially shaped rectangle.
  • the cross section of the protective body has four corners including two rounded corners disposed in the body portion surrounding the first compartment, the two rounded corners being interconnected by a wall set back from the rounded corners so as to define a concave outer face.
  • the cross section of the protective body has two other rounded corners or bevelled disposed in the body part surrounding the second compartment.
  • the protective body is pivotally mounted on support members (pedestals) via end caps, the rounded or bevelled conformation of the corners enables the guard to be pivoted with respect to the support members. This makes it possible, among other things, to facilitate the installation of the support elements on the support (eg wall).
  • the device comprises at least one peripheral seal which is disposed at the interface between each of the open ends of the protective body and the corresponding endpiece.
  • the seals or seals allow the light source to be mounted in a device that limits the risk of water infiltration to electronic and / or electrical components. This therefore limits the damage and / or short circuits caused by water and the infiltration of dust.
  • the base comprises at least one fixing means for fixing the base to a support (eg wall), in particular to simplify the installation of the device on a support.
  • a support eg wall
  • the fixing means is offset relative to the longitudinal axis L of the protective body. This arrangement makes it possible to fix easily to a support the entire device provided with the two ends mounted on their bases without the need to disassemble the end caps of the protective body.

  • Each nozzle also comprises, connected to the recessed portion 5a and extending away from it, a projecting portion 5b which is for example substantially cylindrical.
  • the protruding portion 5b is a connecting portion which cooperates with the base to ensure the rotation of the tip relative to its base. This arrangement makes it possible to turn the endpiece in a plane perpendicular to the axis L, around the projection which is held in position by snapping on the base.
  • the protruding portion 5b is offset from the center of the cover portion 5a towards the end thereof which is closest to the base, to allow rotation of the end piece (and therefore the choice its geometric orientation in space) in a small footprint (height taken perpendicular to the plane of the base).
