Definitions
- the invention relates to a device for illuminating a surface. translucent; it also relates to a luminous sign highlighting works such a device.
- the invention will be more particularly applied to the lighting of a lambrequin.
- awnings Many storefronts are fitted with roll-up fabrics called “awnings", presenting at their free end a bar of load to which is fixed a vertical piece of fabric, called “lambrequin”.
- the lambrequin is more precisely a strip of fabric often scalloped by the bottom, attached to the load bar of a canvas or awning. This piece has no not only aesthetic, but also technical, since it can act as a sign and allow the flow of rainwater.
- neon lights necessarily work under tension relatively high, particularly in the electricity supply sector, i.e. two hundred and twenty volts (220 V), so that the system thus designed does not present not all the security required.
- neon lights are marketed according to determined and standardized lengths, and are in fact non-fragmentable, this which requires the use of standard width fabrics, therefore not suitable for the range of banner blind lengths on the market.
- the neon lights have different lighting, and the scattered light is not uniform.
- Another major disadvantage of neon lights is that they are sensitive to temperature. Indeed, at a temperature below 4 ° C, the ionization is bad and the neon lights very hard, which makes it almost unusable type of lighting during the winter period. Finally, installation is expensive from makes required wiring.
- the problem to be solved is therefore to modify the lighting system of these lambrequins while improving the safety of the device.
- the invention provides a device for lighting a translucent surface by means of a plurality of bulbs, comprising means for fixing said surface, overcoming these drawbacks.
- This device further comprises a support forming a protective cover, consisting of one or more elements end-to-end mounted profiles, made of a dielectric material, each of said profiles elements defining two wings, diverging from the upper end of the elements, and each intended to receive a conductive profiled element of concave internal face electricity, so as to also constitute light reflector, and whose folded upper end abuts against a projection from the junction zone of said wings, each of said elements conductors being brought to a different polarity, thus constituting at the level of said projection the two poles of an electrical supply, these two poles being continuous over the entire length of the support, and intended to allow the setting place in any desired place the two electrodes of one or more bulbs.
- the invention consists in proposing a support offering the continuity of the power source, so the light bulbs can be placed anywhere within the support, thus avoiding sockets required until now, and therefore the discreet positioning of the sources of illumination.
- the bulbs can thus on the one hand, be easily changed, and on the other hand, being mobile, can be moved over the entire length of support. The user therefore has the choice of the number of bulbs and their respective positions.
- conductive profiled elements constitute a continuous socket for the lamps, so that they can be positioned in any place of said conductors, in almost unlimited number.
- these bulbs for example of the halogen type, are advantageously supplied with very low voltages (TBT), so that it thus becomes possible to go from a voltage of 220 Volts to a voltage of twelve volts (12 V) or twenty four volts (24 V).
- TBT very low voltages
- the structure as well described gives the device optimum security.
- the metal profiled elements are fixed on the inner face of the wings by clipping or snapping, the end lower of the wings having a clip member, intended to cooperate with a clip-on member of complementary shape formed at the lower end said metallic profiled elements.
- These elements are made of aluminum, for example, and also provide electrical conduction, also the function of light reflector, specific to reflect the light emitted by the bulbs towards the translucent surface and distributed at the same level.
- the profiled elements have a parabolic profile, the characteristics of this parabola being such, that the burner of the lamps is located at the focus thereof. In addition to optimizing the light output inherent in this positioning, we This also directs the light flux towards the surfaces to be illuminated.
- the lower end respective of each of the wings and of the conductive elements is shaped so that when said elements are clipped onto the wings, they define with them a groove, within which is likely to slide the translucent surface, and in particular a rod mounted on an edge of said surface.
- said leaf spring adopts at level of its upper end a profile identical or similar to that of the curved area of the conductive element. In doing so, this leaf spring gives a certain mechanical rigidity to said metallic element.
- a blade is positioned spring, possibly wider, optimizing the conductivity electric between two consecutive elements, and starting from the poles.
- the translucent surface can be fixed by only one of its borders at the level of the throat defined by the cooperation dielectric wing - metallic profiled element.
- each border of the surface translucent is fixed respectively at the level of the grooves defined at the end free from each of the two constituent wings of the support in cooperation with the metallic profiled elements, the translucent surface then taking the form of a U.
- the upper projection provided at the junction zone of the two constituent wings of the support is extended by a branch, the end of which free is intended to cooperate with said supporting structure.
- the supporting structure is a bar load of an unfoldable or unrollable awning.
- the constituent elements of the support are in one piece and are made of PVC, in particular by extrusion.
- the metal profiled elements are made of aluminum, and are identical regardless of where they are clipped. Indeed, the support being symmetrical, the elements set up within it are as well. In this case, the electrical conduction corresponding to an intensity of a few tens of amps is optimal.
- the invention also relates to a luminous sign of the type with lambrequin consisting of a load bar to which is attached, the entire device described above.
- Figure 1 is a schematic representation of a light sign of the "lambrequin" type according to the invention.
- Figure 2 is a schematic representation in section of the device according to the invention.
- Figure 3 is a sectional view of the cover of the device according to the invention.
- Figure 4 is a sectional view of a conductive profiled element of the electricity of the device according to the invention.
- the installation comprises a shutter (32), capable of being rolled up in a box (33), which is fixed to a wall (30).
- the awning is articulated by a arm (31), at the free end of which is attached a load bar (36).
- the device according to the invention firstly comprises a support (1), acting as a protective cover, in particular for lighting.
- this cover is made up of several elements mounted end to end, fixed to the load bar (36) by means of a branch (6) from said elements, the free end (13) of which cooperates with said bar load (36).
- the device of the invention is connected to a power source electric (35) by cables (34) running at arm level (31).
- the support (1) is made of a dielectric material, typically PVC, and adopts a symmetrical profile, as we can well report on figure 2. It is advantageously obtained by extrusion. It is in fact made up of a plurality of elements of standardized lengths, by example of 1 meter, 1.5 meters, even 2 meters, assembled together up to lead to the desired length. Non-multiple lengths of values standard are made by adding to the standard length profile (s) a profile cut to complementary length.
- These symmetrical elements (1) have two wings (2, 3), extending to from a junction zone (4), and adopting a curved profile.
- the free end (11, 12) of each of the wings (3, 4) first of all has a clip lug (7, 8) from extrusion, then a projection (9, 10), extending substantially perpendicular to the said end.
- junction zone (4) From the junction zone (4), extends in a parallel direction at said ends, on the one hand a projection (5), and on the other hand, the branch (6), intended, as already mentioned, to allow the attachment of the support (1) on the load bar (36).
- the assembly thus formed is in one piece.
- the elements (1) receive at each of their two wings (2, 3) a metallic element (15), for example made of aluminum by wiring, intended to fulfill, in addition to the electrical conduction function, also that of light reflector. It also allows evacuation very efficient heat generated by lamps.
- a metallic element for example made of aluminum by wiring, intended to fulfill, in addition to the electrical conduction function, also that of light reflector. It also allows evacuation very efficient heat generated by lamps.
- This metallic element (15) adopts a substantially corresponding profile with the curved profile of the wings (2, 3), and in particular a parabolic profile. he has at its lower end, on the one hand, a clip lug (16), complementary to the clip lug (7, 8) of said wings (2, 3), and on the other hand, a curved end (17), intended to define with the projection (9, 10) of the wing (2, 3), when the metal element is in place at this level, a groove (38), suitable for receiving the translucent surface (37) to be lit, and in particular, a rod made at one edge or both edges thereof.
- the metallic element (15) has at its other end, a curved portion (18), intended to come into abutment against the projection (5) coming from the junction zone of the element dielectric (1).
- the metallic element is thus dimensioned, so as to be blocked between the projection (5) and the clip lug (8), when it is placed at the level of the corresponding wing.
- the metallic profiled element (15) is identical for the two wings.
- the length of the curved zone (18) of said element substantially corresponds to that of the projection (5).
- it is provided on its two lateral faces of two metallic conductive elements, constituting the two poles of an electrical supply.
- the elements conductors (15) are electrically supplied by cables (34) by the power supply (35), those on the same side of the projection (5) according to a polarity, the others according to the opposite polarity.
- the two poles are therefore separated by the insulating projection (5).
- a continuous socket is produced, capable of receiving directly the lamps, and in particular their electrodes, without requiring any any intermediate element of conduction or fixation.
- this leaf spring imparts a certain mechanical rigidity to said element metallic.
- the electrodes (20) of the bulbs which are inserted between the curved area (18) of the conductive element (15) and the leaf spring (21), said bulbs are firmly held at this level.
- This arrangement optimizes the attachment of the bulbs, and proves to be quite advantageous, taking into account atmospheric conditions, in particular of wind, to which the signs receiving such a device.
- such a leaf spring is positioned, possibly of greater width, optimizing the electrical conductivity between two consecutive elements, and therefore poles, while imparting mechanical rigidity in these areas of junction.
- the unitary elements constituting the support acting cover are mounted end to end, the metal profile elements clipped to the level of their inner side are mounted so that they protrude slightly of said elements on one side, and are slightly set back on the other. This promotes the nesting of a PVC element on the next.
- a terminal cover side of complementary shape, coming to be fixed on PVC elements.
- this device offers optimal security, the bulbs used being low voltage bulbs which can be subjected to cold and humid temperature conditions and therefore perfectly usable during the winter period.
- this device is inexpensive and the bulbs used have a longer lifespan than that of neon lights.
- This system also allows for animated lighting, especially by sequencing, which was previously impossible.
