Definitions
- the present invention relates to a luminaire that can at least partially recessed in a drywall.
- the light fixtures known are of substantially parallelepiped shape with edges possibly rounded so as to present an elongated front face and rounded at the ends.
- a shaped hole corresponding is cut in the partition and the luminaire is introduced by translation in the opening made.
- the shape of the opening corresponds substantially to the shape of the section of the luminaire.
- the main technical problem encountered with luminaires recessed luminaires of the prior art is a problem of heating of the luminaire at inside the partition. Indeed, the interior space of the partition not being ventilated, the luminaire tends to heat up.
- the object of the present invention is therefore to provide a luminaire capable of be built-in for which the heating inside the partition is limited, even when the space to house the luminaire is limited.
- a luminaire intended to be at least partially embedded in a drywall with a front side intended to be at the level of the external surface of the partition as well as a housing intended to be embedded in the partition by an opening made previously in it.
- the recessed housing of the luminaire in its position installed in the partition, has a projecting part which is housed facing the partition, inside thereof and on one side of the opening, and the projecting part has, on the side opposite the front face of the luminaire, a profiled face rounded.
- This projecting part increases the exchange surface between the luminaire and its environment.
- the heat given off by the during operation it drains better, thus limiting overheating of the luminaire.
- the shape of the projection allows the introduction of the housing in a partition even in the case of a limited space (especially in depth) to accommodate this case.
- the projecting part presented by example, on the side of the front face of the luminaire, a substantially flat face and substantially parallel to this front face.
- the edge of the recessed box opposite the front face of the luminaire and opposite the projecting part is preferably rounded.
- the projecting part is advantageously perforated on at least part of its area.
- Access to the interior of the luminaire, and in particular of its housing, is allowed for example thanks to an opening made on the projecting part.
- provision can be made for the face of the projecting part opposite to the front face of the luminaire is constituted by a removable cover.
- the front face of the luminaire is substantially rectangular and the projecting part extends over a long side of this front face, over more than half the length of this long side.
- the height of the projecting part corresponds for example substantially at the height of the front face of the luminaire to obtain good heat exchange in the partition between the luminaire and its environment.
- Figure 1 shows a luminaire 2 intended to be recessed in a partition 4.
- the latter can be a vertical or horizontal partition in the case where it is a ceiling.
- the invention is however more particularly oriented towards luminaires recessed in a vertical partition, or wall, because it is in this case that the problems of heating of the luminaire appear usually. Indeed, the ventilation at the level of the ceilings is better than in vertical partitions. In this case, it is a dry wall 4 vertical.
- the luminaire 2 has a front face 6, a housing 8, closed by the front face 6, and a projecting part 10.
- the front face 6 is of substantially rectangular shape. On the Figures 2 to 6, we only see a small side of this rectangle. This front face 6 includes in particular a transparent or translucent zone surrounded by an edge opaque. This front face 6 is the part of the luminaire which will remain visible once this one recessed. Its shape depends on the aesthetics that one wishes to give to the lamp.
- the housing 8 is disposed behind the front face 6. It contains preferably all the various electrical components necessary for operation of luminaire 2. These components, connections, bulbs, etc. are known from skilled in the art and are not further described here. They depend including the type of bulb used.
- This box 8 is substantially rectangular and its size is adapted the dimensions of the front panel and the depth available for installation of the luminaire.
- the length and width of this case are slightly less than length and width of the front panel.
- the front face forms a rim 12 on at least two sides of the housing.
- the protruding part 10 extends from one face of the housing 8 corresponding to a large side of the front face 6. This projecting part extends parallel to the front face 6 and over almost the entire length of the face corresponding to the housing 8. So, looking at the luminaire from the front, the front 6 hides the housing 8 and we see the protruding part 10 beyond the outline of the front face.
- the height of the projecting part which protrudes from the face before 6 corresponds for example substantially to the width of the rectangle forming this front face.
- This projecting part 10 is preferably substantially empty. As indicated above, the components necessary for the operation of the luminaire are located in box 8. Only possibly cables supply (not shown) pass inside the protruding part 10.
- the rear face of the luminaire, as opposed to the front face 6, is convex.
- the two edges of the assembly formed by the housing 8 and the projecting part 10, extending parallel to the long sides of the rectangle of the front face 6 are in fact rounded to facilitate mounting of the luminaire 2 in the partition 4.
- the front back of the luminaire is perforated at the level of the projecting part 10. Air can thus circulate inside this projection.
- the rear side of this projecting part 10, that is to say the rounded face opposite the front face 6, consists of a removable cover 14.
- the latter is for example fixed on the one hand by two claws cooperating with an edge of the housing 8 and on the other hand by two nipples coming snap onto the front face of the protruding part 10. Any other fixing of the hood may be considered.
- This cover 14 is provided to allow access to the inside of the housing 8 for making connections for example inside this before mounting. This access is facilitated by the absence of components in the projection level 10.
- the mounting of the luminaire 2 in the partition 4 is then carried out by example according to the operating mode described below with reference to FIGS. 2 to 6.
- a first step consists in carrying out an opening 16 in one of the two walls 18 of the partition 4.
- the drywall in which the luminaire 2 is placed has two walls 18 parallel connected together by various means, for example a honeycomb cardboard.
- the walls 18 are for example made of plaster.
- the walls 18 have for example a thickness of 13 or 15 mm while the free space between these two walls 18 is 48 mm.
- the opening 16 made is of a size corresponding to that of the housing 8.
- the size of this opening is less than that of the front face 6. Indeed, once the luminaire in place, the edge of the opening 16 should no longer be visible but hidden by the edge 12.
- the luminaire 2 To introduce the luminaire 2 into the partition 4 passing through opening 16, the luminaire is presented in the position shown on the Figure 2.
- the front face 6 is then substantially perpendicular to the partition 4 and the projecting part 10 is introduced into the opening 16.
- the introduction of the luminaire into the partition 4 then results from a helical movement which is the combination of a translation of the luminaire 2 towards inside the partition 4 and a pivoting of the whole light fixture around an axis perpendicular to the drawing plane in a clockwise direction shows. It is recalled here that the drawing plane corresponds to a plane perpendicular to the front face 6 of the luminaire 2.
- Figure 3 shows the luminaire when the front face 6 is tilted about 45 ° relative to the partition 4.
- the front face of the protruding part 10 is in contact with or almost in contact with the upper edge of the opening 16.
- partition 4 is a vertical partition and that the luminaire must be mounted so that the long sides of the rectangle of the front face 6 are, in the mounted position, substantially horizontal.
- the projecting part 10 is located above the housing 8.
- the rounded rear edge of the protruding part 10 approaches the wall 18 having no opening 16.
- the rear rounded edge of the housing 8 is is located at the lower edge of the opening 16. The presence of these rounded edges facilitate the passage of the luminaire 2 through the opening 16 and allows the installation of a luminaire of larger dimensions than with edges at right angles for an opening of the same dimensions.
- the convex rounded shape of the rear side of the luminaire allows, during the movement of introduction of the luminaire in partition 4, to maintain this rear face substantially tangent on the one hand to the wall 18 not provided with the opening 16 at the level of the part protruding 10 and on the other hand at the edge of the opening 16 at the housing 8.
