- the box thus produced by assembling the two shells 2 and 3 encloses the plate 4 for supporting the diodes, and the block 6 for holding the accumulators, as well as one of the end blocks 8 or 9.
- the assembled housing 1 constitutes the portable lamp as shown in perspective in FIGS. 3, 4 and 6.

- the terminal blocks 8 and 9 are capable of being mounted on the housing 1, alternatively, that is to say that either one or the other is disposed inside the housing.
- Each terminal block 8, 9 is of external dimension (diameter and length / height along the longitudinal axis XX) such that it can be housed in the internal volume formed by the housings 2A and 2B at the proximal end of the housing formed by the two shells 2 and 3 assembled together.
- the first terminal block 8 has a substantially flat distal transverse face (towards the hook 7) while the proximal transverse face (opposite the hook) has a conical shape (more precisely in the form of a funnel, the tip of the cone being turned towards the inside the housing).
- a hole (not shown) is provided centrally in the terminal block 8 so as to communicate the inside of the housing 1 with the outside, and more particularly to allow passage to an electric wire (not shown).
- the wire is connected at one end to the electrical / electronic control circuit provided on the support plate 4, and by the other end to a direct current source or to a transformer, itself capable of being connected to the 'power supply.
- the first terminal block 8 is used in the embodiment of the portable lamp with electrical supply on a source of direct current or on sector via a transformer.

- Figure 5 shows in detail the proximal end (opposite the hook) of the housing 1.
- an electrical wire 30, in a direction substantially in the axis XX.
- the electric wire forms, just after its exit from the terminal block 8, a loop 31 of annular shape.
- the electric wire 30 after substantially three quarter turns at the outlet of the terminal block 8, is held and blocked on the housing 1, and more precisely on the upper shell 2, by means of a notch 32 (FIGS. 2 and 5 ), of generally circular shape (of substantially equal diameter, or even very slightly smaller than that of the electric wire 30), to allow the pinching of the latter.
- a slightly narrowed opening 33 and forming pinch lips are provided between the notch and the transverse end edge of the housing 2.
- the wire is shown in the locked position in FIG. 5. This embodiment makes it possible to prevent accidental traction on the wire, even a slight one, from damaging the lamp at the level of the connection of the electric wire inside the housing.
- this embodiment allows to hang the lamp by the wire.
- the strand 34 of the electric wire 30, after passing through the notch 32 can be hooked to any means of suspension or attachment.
- the portable lamp can be brought as close as possible to the operating area, regardless of the position or the distance of the suspension means.
- the portable lamp of the invention has the advantageous characteristic of being able to rest, in the operational position (FIG. 6) on a horizontal plane.
- the portable lamp has a planar proximal end face (opposite the hook), formed by the end or the end edges of the two shells 2 and 3, then forming an elliptical ring.
- the notch 32 for blocking the wire described above is advantageous (FIG. 6).
- the electric wire then leaves tangentially to a transverse plane, which avoids any curvature or breakage of the wire. This especially makes it possible to produce, at the proximal terminal end of the housing 1, a plane bearing face without the wire projecting from this plane.
- the wire is located above said support plane on which the lamp rests.
- Figure 7 an exploded view of another embodiment of the portable lamp of the invention, where the elements identical or similar to those of Figure 1 have the same references.
- the housing has two straight sections, in particular elliptical, of different radial dimensions, separated by a connection zone.
- Each upper 2 and lower 3 shell is shown in two parts.
- each shell consists of a metal shell coated with a skin.
- the upper shell 2 comprises a rigid metal shell 35, on which a skin or coating 36 of elastomer is attached.
- the lower shell 3 consists of a metal shell 37, coated with a skin or coating 38 as described above.
- the upper shell 2 comprises a window 24 arranged opposite the diodes arranged in a matrix. Said window 24 is able to be covered by the transparent protection plate 25.
- the most important difference between FIG. 1 and FIG. 7, as regards the upper shell 2, relates to the presence in the form of FIG. 7, of an openwork plate 39 made of rigid material.
- the perforated plate 39 can be attached to the shell 2. It can be made of moldable plastic or metal such as aluminum.
- the perforated plate 39 is an integral part of the shell 2. In this case, it is obtained by molding in the same material as the shell 2, namely for example aluminum.
- Lights 40 are provided on said plate 39 and capable of being traversed by the terminal active part of the diodes 5, so that the diodes protrude at least in part with respect to the lights 40 of the plate 39.
- FIG. 8 shows in perspective the metal shell 35 of the upper shell 2.
- the shell 35 has a hole 41 located on the proximal side of the window 24 corresponding to the diodes, for passage and access to the push button 26, through the push button 27 ( Figure 1).
- the perforated plate 39 comprises a series of lights 40 according to a matrix corresponding to the matrix of diodes 5.
- the plate 39 also has ribs in the transverse, that is to say radial, direction which project relative to the upper plane of the perforated plate 39.
- the ribs 42 have the advantage of not altering the optical beams of each set of diodes (here by three) while allowing the plate 39 to be stiffened. Finally, the radial or transverse ribs 42 are at a level such that they protrude radially or transversely with respect to the diodes so as to protect the latter from the mechanical point of view.
- the ribs 42 came directly from molding of the protective plate 25. It is advantageous that the ribs 42, if they came from molding of the perforated plate 39, bear against or are located very close to said transparent protective plate 25.
- the device comprises a housing 1 consisting of two shells 2 and 3.
- Each shell is of generally frustoconical shape with a curved surface.

- the upper shell 2 is made of transparent material, while the shell
- the shells 2 and 3 are made of opaque material.
- the shells 2 and 3 are made of rigid material.
- a plate 4 supporting the circuit and diodes 5 is secured to the housing
- the housing 1 has on its outer face a coating or sheath of elastomeric material, provided with projecting elements 45. These protect the housing 1 in the event of a fall.
- the suspension hook 7 is secured to the housing 1 by elastic interlocking.
- the whole is sealed by elastic fitting, or by gluing, or by welding the shells 2 and 3 and by deformable grommet. 47 at the outlet of the power cable 46.
- the seal between the hook 7 and the shell 2 is produced by compression and elastic deformation of the sheath or elastomer coating. This compression has the additional role of slowing the rotation of the hook to impose a direction on the suspended device.
- the face of the shell facing the diodes comprises lights 48 coinciding with the LEDs 5 and able to be crossed by the terminal part of the latter.
- the housing 1 combines, by bi-injection for example, a rigid material which can be opaque and a sheath, skin or coating 49 of elastomeric material allowing sealing by elastic deformation with the LEDs 5.
- the shells are made of a rigid material, thermoplastic for example.
- the diode support plate 4 5 is fixed to the housing by screwing or bolting.
- the projecting elements made of elastomeric material constitute a partial sheathing of the device housing.
- FIG. 11 shows the electronic supply circuit for the diodes, which includes a PWM (Puise Width Modulation) regulator with pulse width modulation making it possible to deliver to the LEDs a control and lighting current controlled and controlled at the voltage values. nominal and nominal current of the LEDs.
