 - Figures 1 1 and 12 are sectional views that illustrate two steps of mounting the lighting system according to the invention.

 The lighting system 1 illustrated in Figures 1 to 3 is intended to equip a pool wall P, in particular a vertical wall P (shown in dashed lines).

 This lighting system 1 is intended to be disposed below the level of the surface of the pool of the pool, that is to say intended to be completely immersed in the pool water.

 For this, this lighting system 1 comprises a lighting device 2 secured by interlocking with a wall-passing member 3.

 The wall penetrating member 3 is in the form of a cylindrical sleeve of axis X provided with an outer surface 31, and an inner surface 32 having a female thread 33.

 This wall through member 3 allows delimiting a through passage 5 within said wall P (the X axis of this through passage 5 is here horizontal). It advantageously comprises a flange 34, for bearing against the face of the wall P delimiting the swimming pool.

 As illustrated in Figure 1, the wall through member 3 may be positioned in the wall P pool pool, for example made of concrete, at the time of construction of the latter. For swimming pools consisting of a prefabricated hull, this wall traversing member 3 is fixed through a suitable orifice, by means of a nut positioned on the side of the outer face of the shell and cooperating with the thread which is arranged on its outer surface 31.

 In this case, this wall feed member 3 advantageously consists of a system called "brush plug" provided with a female thread 33 of gas type one inch and a half.

The lighting device 2 comprises a lighting support 21, lighting means 22, fixing means 23 of said lighting support 21 on the wall-passing member 3, and a power supply cable 24. . the lighting support 21 is in the form of a flange, made by plastic molding, provided with a front face 21 1 (intended to be oriented towards the pool of the pool), a rear face 212 (intended to be directed towards the wall P) and a through hole 213, here central, of generally circular shape and diameter d.

 This lighting support 21 has a bulk greater than that of the wall-passing member 3, so that its rear face 212 is adapted to be pressed in front of the wall-through member 3, against the part of the pool wall P which surrounds said wall penetration member 3.

 The through orifice 213 is delimited by a tubular section 214 which protrudes from the rear face 212 (that is to say towards the wall P).

 The tubular section 214 extends coaxially with the through orifice 213; it has an inner surface 214a, an outer surface 214b and ends with a circular end edge 214c (Figures 2 and 3).

 The front face 21 1 of the lighting support 21 serves to support the lighting means 22 which consist, in a conventional manner, of a set of light-emitting diodes, or the like, controlled by an electronic management unit.

 These lighting means 22 are covered, again in a conventional manner, by an optical system or lens (s).

 The means 23 which allow the fixing of the lighting support 21 to the wall-passing member 3 comprise:

 an interlocking connection 23a integral with the lighting support 21, provided with first interlocking means 23a1 (here of the male type), and

 b / a fixing ring 23b provided with a male thread 23b1 adapted to cooperate with the female thread 33 of the wall penetration member 3; and which also comprises second interlocking means 23b2 (here of the female type) adapted to cooperate with said first interlocking means 23a1 of said interlocking fitting 23a.

 The interlocking connection 23a here consists of a plastic part made independently of the lighting support 21 and which is secured by bonding with the latter. In an alternative embodiment, the interlocking connection 23a can be made in one piece with the lighting support 21.

 This interlocking connection 23a is shown in isolation in FIGS. 4 to 6.

It is in the general form of a Y-axis tube provided with a rear end 23a2, a front end 23a3 (opposite to said rear end 23a2), an outer surface 23a4 and an inner surface 23a5.

 The first interlocking means 23a1 of this interlocking fitting 23a consist of an annular groove formed at the front end 23a3, in its outer surface 23a4. This annular groove 23a1 has a section in an arc.

The outer surface 23a4 of the interlocking fitting 23a further comprises a annular flange 23a6, which protrudes in its middle part.

 On the other hand, the front end 23a3 of the interlocking fitting 23a has an end wall 23a7 provided with an orifice 23a8 (here an axial orifice centered on the Y axis).

 The end wall 23a7 defines an internal shoulder 23a9 on the periphery of the axial orifice 23a8.

 In this case, this shoulder 23a9 is in the form of pan inclined relative to the Y axis. Here, the corresponding inclination is of the order of 45 °.

 On the side of its rear end, the inner surface 23a5 of the interlocking fitting 23a has a tapping 23a10.

 At the rear end 23a2 of the interlocking fitting 23a, the diameter of the outer surface 23a4 corresponds, with clearance, to the diameter of the inner surface 214a of the tubular section 214 of the lighting support 21.

 The rear end 23a2 of the interlocking fitting 23a is secured to the tubular section 214 of the lighting support 21 by bonding the outer surface 23a4 of said interlocking fitting 23a with said outer surface 214a of said tubular section 214.

 This bonding assembly is carried out by inserting the rear end 23a2 of the interlocking fitting 23a into the tubular section 214, until the annular flange 23a6 bears against the end edge 214c of the tubular section 214 ( see Figures 1 and 2).

 Then, the interlocking fitting 23a extends from the rear face 212 of the lighting support 21, coaxially with the through hole 213 of this lighting support 21, with its front end 23a3 (provided with the throat annular 23a1) which projects.

 The power supply cable 24 passes through the orifice 23a8 formed in the end wall 23a7, and through the through hole 213 of the lighting support 21, to supply electricity to the lighting system 22. (ie the electronic management unit and the light-emitting diodes).

 A gland type seal system is provided at this level to seal around the power cable.

 For this, an annular seal 25 is tightened / compressed around the supply cable 24, against the internal shoulder 23a9 of the interlocking fitting 23a, by means of a clamping nut 26.

 This clamping nut 26 has a central orifice 26a for the passage of the power cable 24, and a peripheral thread 26b adapted to cooperate with the thread 23a10 of the interlocking fitting 23a.

 After passage of the end of the power cable 24 in the central hole 26a of the clamping nut 26, the latter inserted through the through hole 213 of the lighting support 21 and the rear end 23a2 of the fitting nipple 23a, is screwed on the tapping 23a10 so as to compress the seal 25 of the gland system.

This screwing is carried out by means of indentations 26c formed in the rear end of the nut 26 (Figure 1 and 3).

 Preferably, a washer 28 is interposed between the seal 25 of the glanding system and the clamping nut 26 to constitute a translational pressure member by virtue of the sliding washer 28 / nut 26 and the joint adhesion 25 / washer 28.

 The fixing ring 23b consists of a piece of plastic material shown in isolation in FIGS. 7 to 10.

 This fixing ring 23b has a generally annular or tubular shape, Z axis, having a rear end 23b3, intended to be oriented on the side of the lighting support 21, a front end 23b4, opposite said rear end 23b3, a outer surface 23b5 and inner surface 23b6.

 The outer surface 23b5 of the ring 23b comprises the aforementioned male thread 23b1, adapted to cooperate with the female thread 33 of the wall penetration member 3;

and the inner surface 23b6 of the ring 23b comprises the aforementioned second female engagement means 23b2, adapted to cooperate with the first interlocking means 23a1 of the interlocking fitting 23a.

 These second female-type engagement means 23b2 are constituted by a plurality of tongues 23b21 which extend the rear end 23b3 of the fixing ring 23b, and which comprise a radial deformation capacity.

 These tongues 23b21 are at least two in number, preferably at least four in number, and here six in number, evenly distributed around the inner surface 23b6 of the fixing ring 23b.

 Each tongue 23b21 extends integrally from the rear end 23b3 and towards the front end 23b4, parallel to the axis Z, and their free end comprises a nesting pin 23b22 oriented towards the axis Z.

 The connection of the tongues 23b21 with the rear end 23b3 is in the form of a half circle and constitutes a hinge conferring the aforementioned radial deformation capacity.

 The tabs 23b21 extend from the rear end 23b3 to the front end 23b4 of the fastener ring 23b, i.e. all or substantially all the width / thickness of said ring 23b.

 The various interlocking lugs 23b22 are regularly distributed over a locking ring which extends in the thickness of the fixing ring 23b.

 The tabs 23b21 with the interlocking lugs 23b22 constitute the second interlocking means 23b2, arranged to cooperate with the first interlocking means 23a1 constituted by the end of the connecting tube 23a provided with the annular groove 23a1.

The desired interlocking is achieved by engagement of the engagement lugs 23b22 of the fixing ring 23b in this annular groove 23a1 of the connecting tube 23a. Lighting system assembly

 The lighting device 2 is prepared before assembly, equipped with the power cable 24 which extends from the lighting system 22 through the through hole 213 of the lighting support 21 and the 23a8 orifice of the fitting fitting 23a, sealed by the glanding system 25, 26.

 As illustrated in Figure 1 1, the fixing ring 23b is prepared and presented opposite the wall through member 3 fixed in the wall of the pool to be equipped.

 Then, as illustrated in Figure 1 1, the fixing ring 23 is screwed into the wall-through member 3, on the female thread 33, to a suitable depth level; and the supply cable 24 is threaded through said fixing ring 23 and thus through the wall-passing member 3.

 Finally, the lighting device 2 is fixed against the wall P of the swimming pool, as illustrated in FIG. 1, by fitting of the nesting tube 23a into the fixing ring 23b, by cooperation with the interlocking lugs 23b22 of the tongues. flexible 23b21 with the annular groove 23a1.

 The corresponding interlock is adjusted so that the rear face 212 of the lighting support 21 comes to be pressed against or virtually pressed against the part of the pool wall P which surrounds the wall penetration member 3.

 This provides a quick and easy attachment. This attachment is dismountable by disengagement, by inserting a tool for levering between the wall P and the periphery of the lighting support 21 (this by means of adapted openings provided at the peripheral edge of the lighting support 21).
