  • The second cylindrical plug 14 has a planar end face 15, thus allowing the inspector to rest vertically on a horizontal support, perpendicular to the axis (X-X).
  • As will be explained later, the second cylindrical plug 14 must be inserted by deformation in the casing 1, when the assembly of the portable lamp, to allow a better waterproofness of the portable lamp.
  • The first 10 and second 14 cylindrical plugs have means for centering and / or positioning (16, 17) of the support plate 6 as well as electrical connection means (18, 19) of the cells 9 for transmitting the energy contained in the batteries 9, when the device is assembled.
  • The pushbutton 13 is connected in known manner to the diodes 7 according to an electric circuit represented by the electronic / electrical means 8.
  • The second cylindrical plug 14 may be of two types: either it has a flat surface 15 allowing a connection with a charger (not shown here but of any known type) by means of electric charging means of the accumulators, and thus the device according to the invention. invention operates exclusively from an energy source in the form of rechargeable batteries, or it is connected to an electrical wire (not shown here) for said device to operate, or on a sector from an electrical outlet via a transformer of known type per se, either on a supply of a continuous source.
  • The Figures 3 and 4 represent the housing of the figure 1 according to two different angles of view.

  • The housings (20, 21, 22) all have the same length but are all slightly shorter than the length of the housing 1.
  • In this way, the housing 1 has at its two ends a recessed portion allowing the insertion of the first 10 and second 14 cylindrical plugs therein.
  • The insertion of the first 10 and second 14 cylindrical plugs is by partial elastic deformation thereof.
  • Thus, the waterproofness of the portable lamp in the assembled state is always achieved.
  • The figure 5 represents an exploded view of the different elements that make up the portable lamp.
  • The housing 1 is covered with a sleeve 23 of flexible semi-rigid material, such as elastomer. The sleeve 23 is preferably affixed by overmolding.
  • The sleeve 23 completely covers the casing 1 excluding the parallelepipedal window 4 opposite the diodes 7 where it has a cutout.
  • The sleeve 23 is of uniform thickness except, possibly, at the opening 5, and is ideally polyurethane.
  • A perforated plate 24, of the same length as the support plate 6, fits on the plate 6 and has slots 25 allowing each of the light-emitting diodes 7 to fit into each of the slots 25.
  • The perforated plate 24 thus comprises as many lights 25 as light-emitting diodes 7.
  • Such interlocking allows the light-emitting diodes 7 to be disposed inside the volume of the housing 1 and ensures better protection of the diodes 7, for example in case of a fall.
  • In addition, the perforated plate 24 has an orifice 26 allowing the push button 13 to protrude from the plane of the perforated plate 24 when the latter and the support plate 6 are nested one on the other.
  • The support plate 6, in interlocking connection with the perforated plate 24, is inserted by translation at the end of the lighting part 3 inside the first semi-cylindrical housing 20 and rests on the rectangular flat zone. 20A of the half-cylinder 20 which is perpendicular to the axis (XX).
  • The housing 20 thus allows the establishment of the support plate 6 fitted with the perforated plate 24.
  • The support plate 6 is then held in position by the first 10 and second 14 cylindrical plugs which both have means for centering and / or positioning (16, 17) of said support plate 6.
  • According to the particular representation of the portable lamp, it operates by means of six batteries 9 of the LR6 type which can be inserted in groups of three in the second 21 and third 22 housings inside the housing 1.
  • Once the batteries 9 and the support plate 6 connected to the perforated plate 24 inserted in the housing 1, the first cylindrical plug 11 fits into the end of the lighting portion 3.
  • The second cylindrical plug 14 also fits into the end of the gripping portion 2.
  • The second cylindrical plug 14 is held in position by means of a connecting ring 27 of a type known per se.
  • The figure 6 represents the portable lamp that can be used.
  • The housing 1 is covered with the sleeve 23 which covers the opening 5 but not the parallelepipedal window 4 of the housing 1 facing the diodes 7.
  • The wiper obtained is perfectly tight because of the small number of links between the various elements, that is to say between the first cylindrical plug 11 and the housing 1 at the end of the lighting portion 3 and between the housing 1, the connecting ring 27 and the second cylindrical plug 14 at the end of the portion of the grasping 2.
  • The portable lamp thus formed has a power-on zone 28.
  • Indeed, during the engagement of the perforated plate 24 with the support plate 6, the push button 13 protrudes from the pan of the perforated plate 24 and can therefore always be activated or deactivated.
  • The insertion into the housing 1 of this set of plates (6, 24) does not prevent access to the push button 13 since the circular opening 5, located next to said push button 13, provides access to it. this.
  • The sleeve 23 of elastomer having, at the level of the push button 13 and the circular opening 5, a reduced thickness relative to the remainder of the surface of the sleeve 23, a low pressure exerted by the finger of the user at the level of the power-on zone 28 activates (or deactivates) the push-button 13 through the sleeve 23, and thus enables the device according to the invention to be energized.
  • Thus, the tightness of the device is not affected by the area of the power-on point 28.
  • According to another preferred representation of the invention in the figure 7 where the elements similar to those of the preceding figures bear the With the same reference numerals, the support plate 6 has a detachable part 29 consisting of:
    • said illuminating elements 7 in the form of light-emitting diodes;
    • a transparent protective window 30 of generally semi-cylindrical shape with a longitudinal axis parallel to the longitudinal axis of the housing 1, facing said illuminating elements 7;
    • detachable fixing means of said removable portion 29 on said housing 1, said removable fixing means being composed of first 31 and second 32 connecting means of said removable portion 29 to the housing 1, said housing 1 having first 33 and second 34 connecting means of said housing 1 to said connecting means (31, 32).
  • The removable part 29 has a parallelepipedal general shape which fits into the casing 1 by insertion of the first connection means 31 into the first connection means 33 and by fitting of the second connection means 32 with the second connection means 34.
  • According to figure 7 the first coupling means 31 are of generally parallelepipedal shape and fit into the first connection means 33 (not shown in the figure), but which have a shape complementary to the first connection means 31.
  • After insertion of the first coupling means 31 in the first connecting means 33, it is then possible to completely fit the removable portion 29 in the housing 1 by contacting the second means of connection 32 with the second connecting means 34 and a slight pressure exerted, for example, on the protection window 29.
  • The first coupling means 31 also have electrical connection means (of known type) allowing the illuminating elements 7 to be electronically connected to the electrical / electronic control means 9.
  • According to figure 7 , the second connecting means 32 are constituted by a recess in the removable portion 29 and the second connecting means 34 are constituted by a projecting element in the housing 1, the shape of the projection being complementary to the shape of the recess.
  • Preferably, the housing 1 has a receptive housing 35 of complementary shape to the shape of the removable portion 29.
  • Preferably, the illuminating elements 7 are designed to emit in the visible or ultraviolet range.
