Definitions

  • This invention relates to a light fixture for diversified lighting with a sliding lampshade and a system for diversified room lighting, particularly office or factory rooms,
  • the fundamental parameters of the lighting environment that should be taken into consideration when designing room lighting include:
  • the international patent publication WO2020057982A1 discloses a system for fastening to a suspended collector rail.
  • the collector rail extends along a longitudinal axis and has multiple snap fasteners.
  • the system has two parts of a side profile. One may easily connect the parts of the side profile to the snap fasteners of the collector rail using snap fits.
  • the object of the present invention is to propose a light fixture and a whole system comprising a light fixture according to the invention, which makes it possible to change the illumination produced by the light fixture without the necessity of replacing the lampshade (or diffusor) or the whole light fixture.
  • the subject matter of the invention is a light fixture equipped with mutually slidable elements, with a possibility of snap fits.
  • the light fixture has a body comprising a reflector fixedly built-in within it, and the body has at least two retaining-locking recesses on the internal surface of its vertical wall, with which cooperates at least one projection located on the external surface of the wall of the lampshade, the lampshade being slidable relative to the body in the direction of the body outlet or body interior.
  • the light fixture has at least three retaining-locking recesses.
  • a retaining-locking recess may be in the form of a longitudinal or circumferential groove, or it may be a spot recess with a flat bottom and with a circular or polygonal cross-section, or with a cross-section of any geometric shape.
  • the retaining-locking recess extends linearly along the longitudinal axis on the two opposite sides of the body.
  • the projection may be spot-wise or linear, with the external surface having a frustoconical shape, a spherical sector shape, a prismatic shape, or in the form of a longitudinal or peripheral double-bending.
  • projections cooperate with spot-wise retaining-locking recesses, the projections being distributed on the wall of the lampshade symmetrically relative to the spots of the retaining-locking recess.
  • projections may have the external surface having a frustoconical shape, a spherical sector shape or any frusto-pyramidal shape, or any prismatic shape.

  • the retaining-locking recesses extend linearly along the longitudinal axis on the two opposite sides of the body symmetrically or asymmetrically.
  • the lampshade may be "clicked" into the light fixture in many positions by placing the projection within a selected retaining-locking recess.
  • the light fixture may: a) shine widely, then the lampshade projects from the light fixture, or b) shine with a medium focus, then the lampshade is flush with the profile, or c) shine narrowly, then the lampshade is retracted in the light fixture.
  • the body may have any arbitrary number of retaining-locking recesses, for example, two, four, five, or more retaining-locking recesses. To obtain the selected shining effect, one moves the lampshade relative to the body toward the outlet of the body or interior of the body.
  • the retaining-locking recess may be in the form of a longitudinal or peripheral groove, for example, having a cross-section in the form of a right trapezoid, a triangular, tetragonal, or hexagonal prism.

  • the shape of the projection is matched to the shape of the retaining-locking recess.
  • the body is built similarly to the first embodiment, and it has retaining-locking recesses (for example, three) on the internal surface of the vertical wall.
  • the retaining-locking recesses on the vertical wall have a form of arbitrarily located spots.
  • the retaining-locking recesses may have a form of serially, horizontally distributed spots extending along the longitudinal axis on one or two opposite sides of the body. However, more preferably, they extend along the longitudinal axis on the two opposite sides of the body. Every retaining-locking recess is created by a line of spots.
  • the term line of spots or spot-wise distribution means an arbitrary number of spots arranged in arbitrary distances each from other creating a line (straight line, a curve, zigzags, arcs, patterns) that extends through the whole length of the body or only through a part thereof. It is also possible that every retaining-locking recess is a separate line of spots.
  • the first retaining-locking recess is a straight line of spots
  • the second retaining-locking recess is a line of spots creating a sinusoidal wave.
  • the retaining-locking recesses may be created in one line or, for example, in two parallel lines.
  • the retaining-locking recesses extend along the longitudinal axis on the two opposite sides of the body symmetrically or asymmetrically.
  • the spots also called openings in the context of the present invention, are openings of any shape, for example, in the form of circles, ellipses, squares, rectangles, triangles.
  • the projections may be inserted into every opening of the line of spots or only into selected openings - for example, every second or every third opening.
  • Openings (interchangeably called spots) in the line of spots have dimensions from 0.5 mm to 20 mm, preferably from 1mm to 10 mm, and most preferably from 1 mm to 6 mm.
  • the connection of the retaining-locking recess and the projections located on the external surface of the lampshade wall is spot-wise.
  • the shape of every single projection in this embodiment is matched to the shape of the corresponding opening in the line of spots of the retaining-locking recess.
  • the retaining-locking recesses may be spot-wise, of a round cross-section and a flat bottom or spot-wise of a polygonal cross-section and a flat bottom.
  • the projections are spot-wise, distributed on the wall of the lampshade symmetrically to the line of the spots of the retaining-locking recess and, for example, their external surface has a frustoconical shape, a spherical sector shape, or any frusto-pyramidal shape.
  • the external surface of the wall of the lampshade and the projections and/or projection placed thereon may be made from aluminum, steel, or plastic material.
  • the position of the lampshade relative to the body may be changed by manual deflecting the projection and/or projections beyond the recesses sliding the lampshade inside the body, depending on the shining effect one wants to obtain, toward the outlet or interior of the body.
  • the subject matter of the invention is a system for diversified room lighting comprising a set of at least two light fixtures according to the invention. Every light fixture in the set has its individual setting by setting the lampshade relative to the body in any retaining-locking recess. The individual setting of a given light fixture ensures the desired general shining and/or spot shining and/or combined shining for different zones of the illuminated room.
  • the set of the light fixtures consists of at least two light fixtures linearly connected with each other or separate light fixtures arbitrarily distributed in the room.
  • first, second, third as used in the specification and claims have the function of differentiating similar elements and do not define any sequential or chronological order. It is to be understood that the terms used in this way are interchangeable in corresponding circumstances and that the described embodiments of the present invention may operate in other sequences than the described or illustrated in the present document. According to the invention, a user may use only one retaining-locking recess for the whole period of using the light fixture, or he/she may change the light emission through the light fixture on his/her own.
  • the term "cooperates” means changing the position of the lampshade relative to the body by manually deflecting the projection and/or projections beyond the retaining-locking recess, sliding the lampshade inside the body, and clicking the projection and/or projections into another selected retaining-locking recess.
  • the advantage of the solution according to the invention is the possibility of changing the way the light fixture shines without the necessity of replacing the lampshade or the whole light fixture.
  • an investor/user wants to change the nature of the illumination produced by light fixtures in a given room, for example, from narrowly shining into a wide focus of the light, he/she does not have to replace the light fixtures nor components in the light fixtures, but only change the level of the lampshade from the first retaining-locking recess into the second or yet subsequent retaining-locking recess.
  • the body of the light fixture according to the invention may have any arbitrary number of retaining-locking recesses.
  • Another important feature of the present solution is that they may consider using one universal light fixture instead of several different designs and may obtain various shining nature only by changing the position of the lampshade in the light fixture, whereby they may arrange designed space in different ways.
  • Using the light fixture or the whole system according to the invention is cheaper when obtaining diversified lighting.
  • the following description presents embodiments of a system for diversified room lighting, particularly office or factory rooms, and a universal light fixture that makes it possible to change the illumination without the necessity of replacing the lampshade and/or the whole light fixture.
  • the shining may be changed by a simple movement of the lampshade relative to the lamp's body, not requiring any special skills nor changing equipment.
