Definitions

• the present invention is in the field of lighting and relates more particularly to a light bar.
• European patent application EP-0.375.623 which relates to a lighting ramp having a succession of pairs of electrical contacts comprising at least two superimposed conductive strips having at predetermined distances plates arranged at 90 ° to supply series of bulbs arranged between two adjacent contacts.
• the conductive strips are each covered by a continuous insulating body over their entire surface, so as to form a stack in which the conductive strips are completely isolated from each other and towards the outside, excluding the contact plates.
• European patent application EP-516.578 the applicant proposes that the conductive strips be slid into a profile having a central clearance for the conductive strips and an opening allowing the contact pads to pass freely.
• the present invention relates to an improvement intended more particularly for lighting when, for practical reasons, the ramp must be located so that the beam is oriented upwards without the ramp having any possibility of being under protection and being therefore subject to bad weather.
• waterproof ramps must be provided, an advantage offered by this invention.
• the ramp according to the invention comprises a base profile having two lateral wings, an electrical supply ramp being placed inside the base profile. It is characterized by a transparent plastic profile cut to a dimension slightly higher than that of the base profile, in the longitudinal direction and comprising two edges which collaborate with the lateral wings of the base profile so as to completely cover them by surrounding them, two aluminum covers, able to collaborate with the profile base and the transparent profile being placed at the ends of the ramp and so as to surround the transparent profile and the ends of the wings of the base profile.
• the transparent plastic profile a polycarbonate or an acrylic material on occasion, is an extruded plastic.
• the two aluminum profiles are also extruded. This embodiment makes it possible to design ramps of modular length in different dimensions which can go up to 300 cm.
• the ramp may advantageously have orifices in its lower part so as to be able to evacuate from its interior the water produced by condensation.
• Figure 1 is a general perspective view of a light bar.
• Figure 2 is a cross section of the light bar of Figure 1, along the line II-II.
• Figure 3 is a detailed representation of the closure tip to be placed at the end of the ramp, just inside the aluminum cover.
• the light bar 1 is composed of a base profile 2, of a plastic profile 3, of an aluminum cover 4 placed at each end of the light bar 1 and of two aluminum profiles 5.
• FIG. 2 is represented one of the orifices 6, which will allow the evacuation of the water produced by condensation inside the ramp.
• FIG. 3 is shown a closing end piece 7 with the orifice 11 for a conductive wire 12 as well as the orifices 9 for the fixing screws 10.
• the electrical supply ramp and the parabolic reflector are not shown for simplification of the drawing.
• the aluminum cover 4 has an upper part which exceeds the length of the base profile 2, as well as the aluminum profiles 5, this to allow the transparent plastic profile 3 to expand during temperature variations when the light bar 1 is on.
• the transparent plastic profile 3 in an advantageous embodiment is produced by extrusion in transparent polycarbonate, such as macrolon or plexiglass; this allows the dimensions of the ramp to be adjusted, so that one can go from very small lengths to lengths of 300 cm. It includes a central part with edges 31, which collaborate with the upper ends 21a, 21b of the base profile 2, to finish with two wings 32 which partially surround said ends 21a, 21b.
• the outer face of the wings has grooves to better adapt to other surfaces when the transparent profile undergoes the effects of expansion and shrinkage.
• the aluminum profiles 5 can also be manufactured by extrusion and can be adapted to the same dimensions as the transparent plastic profile 3. These aluminum profiles 5 end with rounded slides 13 which collaborate with the rounded slots 12 of the base profile 2 , so as to slip into their interiors and remain fixed throughout the ramp. The aluminum profiles 5 press the plastic profile 3 against the edges of the base profile 2 and hold it laterally. As a result, the aluminum profiles 5 prevent any deformation of the plastic profile 3.
• the base section 2 allows the introduction of an electrical supply ramp inside and for this has in its lower part an enlargement 14 to receive said ramp which is not shown in the drawing.
• the grooves 15 serve to slide a parabolic reflector, not shown, in order to transmit a beam of light concentrated on a precise direction.
• the grooves 16 are used to advantageously place one or more diffusion grids, not shown, in order to prevent the light from being reflected in an undesired way.
• One of the 2lb wings of the base profile will have an outer edge inclined to facilitate mounting of the transparent plastic profile 3.
• a lug 17 and a special groove in the part 18 allow the ramp 1 to be fixed on a support, not shown, of a fixing piece, by a simple clipping operation.
• Each fixing piece can be used with a screw to adjust the orientation of the assembly in a specific direction.
• the ramp can thus be easily disconnected for maintenance work, in particular for changing lamps.
• the orifices 8 collaborate with the corresponding orifices 9 of the closure end piece 7, so that the assembly, base profile 2, end piece 7 and covers 4, is fixed by the screws 10.
• the holes 20 will collaborate with the studs 19 of the closing end piece 7.
• This end piece which includes the studs 19 and the orifices 9, has a perimeter adapted to the base profile 2 and remains integral between the latter and the aluminum covers 4
• the orifice 11 will be used for the passage of the electric wire 12.
• the upper part of the covers 4 allows the plastic profile 3 and the aluminum profiles 5 to have a length slightly greater than the rest of the elements of the ramp. This takes into account the phenomenon of expansion and shrinking which in the case of a ramp of 300 cm in length can reach up to 15 mm for a polycarbonate or an acrylic material.
• the ramp which has just been described is thus presented as a waterproof lighting ramp, practically undeformable with variations in temperature, with the possibility of being adjustable to reach a maximum dimension of 300 cm, without problems of condensation at its interior, easy to assemble and very simple to disassemble from its support.
