Definitions

• the invention relates to lighting systems and linear light decoration of small section whose light sources are small incandescent lamps.
• Each consists of a series of lamps, which can be supplied directly from the mains, connected in parallel to two conductors arranged in the axis thereof, the whole being coated with a transparent or translucent resin so that the conductors are flush with the ends of the module in an arrangement which allows the embedding of two adjacent ends in a connection which provides the electrical connection.
• This system suffers from a drawback, the confinement of the lamps which thus see their life shortened. It suffers, with those who 'use a sheath, a second drawback, a loss of luraine flow when used for lighting, luminance when used in lighting decoration. Finally this. system has a drawback deny specific; when you replace an out-of-use module, you also replace the supply conductors, which is a waste.
• Each consists of a series of lamps, the supply voltage of which is that of the sector.
• Each terminal in the series is connected to a contact element, plate or copper pin.
• the whole is coated with a transparent resin (translucent to obtain certain lu ⁇ sinous effects) so that the contact elements are flush or emerge from the block which constitutes the coating and that the lamps are flush where they are partially uncovered.
• the coating block has the shape of a rectangular parallelepiped.
• the modules are inserted "by force" into a "U" support, straight or not, which contains two conductors, stripped at least at the contact elements of the modules, connected to the sector at the end of the support.
• the U-shaped support will have its conductors arranged on the internal face of each wing.
• the conductors will be arranged on an elastomer or foam profile (it is therefore the compressibility of these profiles which will ensure that the modules are held in place and the quality of the contact electric); if the coating resin is compressible after polymerization (elastomer), the conductors will be placed directly on the internal face of the wings of the support which will be adequately profiled to receive the conductor (in this case, it is the compressibility of the resin coating which keeps the modules in place and the quality of the electrical contact).
• the conductors will be arranged at the bottom of the support embedded in an elastomer profile; this will include two longitudinal slots along the entire length of the support, plumb with the conductors, in order to allow the passage of the contact pins (in this case, the pins which enter "forcefully” into the slots of the profile elastomer which contains the conductors and it is the pressure on these pins which keeps the module in place).
• This system has several advantages over existing systems. It works without transformer since each series of lamps can receive the current of the sector. The replacement of an off-module sçrvice requires no technical knowledge, no tools, no know-how; it's as simple as that of a standard incandescent lamp in a home fixture.
• FIGS. I, 2 and 3 An embodiment of the system described (FIGS. I, 2 and 3) consisted in coating ten small la-spes (i) with incandescent 24 volts of unit tensi ("luciol” from MAZDA), connected in series, the terminals of the series having been soldered to two small copper plates (2). The whole was coated in a colorless transparent epoxy resin (3) ("In Epox" sold by the company ADAM) so that the two copper plates are flush and the lamps are partially uncovered.
• luciol unit tensi
• the support ( Figure 3) was made by molding two profiles (4) in silicone elas tomera ("RTV 589" from RHONE POULENC) on which was glued a copper strip (5) of 0.5 X 2 mm section, each connected to the sector at the end of the support, each profile having been glued to one of the wings of an aluminum profile (6) in a "U" shape.
• the realization of a module poses the problem of the mold. Indeed, to obtain that after demolding the light elements are flush or are partially uncovered, while preserving the possibility of carrying out the coating in a single casting or injection, it is necessary to arrange the mold in a particular way.
• the molding-coating system designed consists of placing on two internal faces of the mold in opposition an elastomer or foam lining covered with a plastic film allowing easy demolding, that is to say having in the mold two compressible opposing faces.
• the light elements can be positioned in the mold by lowering them "in force", the electrical connection between them having been made before.
• FIG. 4 An embodiment of the system ( Figures 4 and 5) consisted of a rectangular parallelepiped mold open in three parts J a bottom (l) of metal inserted between two faces each consisting of a metal flat (2) on which has been stuck a strip of adhesive foam (3) covered with an adhesive film of polytetrafluoroethylene (sold by "3M") (4); two silicone elastomer plugs (5) were placed at the ends and the whole was sufficiently compressed by clamps to ensure the seal.
• the casting was carried out by gravity after positioning the series of lamps (6) and copper plates (7) serving as terminals. For positioning in the mold, the plates were glued to two small studs (8) of the same resin as that used for the coating.
