Description

Security lighting device

The present invention relates to a safety lighting device comprising a housing housing at least one lighting means adapted to be electrically connected on the one hand to an electrical network and on the other hand to an electric accumulator adapted to supply in case of failure of the electrical network, said lighting means being movable between a retracted position and a deployed position relative to a face of said housing and being able to rotate 360 ° about an axis perpendicular to said face of the housing .

Conventionally, safety lighting devices are intended to continue to broadcast a light signal in case of accidental interruption of normal lighting. Current regulations require that they be placed in public places to allow the movement of people and, if necessary, to evacuate them by limiting any risk of panic. They must also allow, if necessary, the rapid arrival and consequently an effective intervention of the helpers.

Thus, such devices play the role of light beacons materializing a path to an emergency exit or to an incident site. The lighting generated should preferably be uniform, and especially as it also allows the public to identify possible obstacles and changes of direction.

Depending on the case, it is possible to use enclosures incorporating backlighting means of a signage that has their front face. Such boxes may also include additional lighting means, external to the housing, and diffusing light to a given area.

Various devices of this type are known from the state of the art.

Publication US 7,520,072, for example, describes a security block in the form of a housing whose front face includes cutouts forming the word "exit", backlit by a plurality of LED lamps. Furthermore, the underside is equipped with LED spots that can adopt a retracted position and an extended position in which they can also be oriented in a given direction by rotation about an axis.

The publication US 2011/0103037 describes for its part a safety lighting unit comprising two spots each fixed in a recess of a housing by means of a hinge. In fact, each spot is movable between a rest position in which it is retracted into its recess and illuminates nothing, and an active position, in which it is extracted from its recess, by pivoting about the axis of the hinge . Adjusting the spot's pivot angle around the hinge axis allows you to select the desired illumination angle.

The present invention is intended to propose a new safety lighting device comprising at least one moving lighting means between a retracted position and an extended position, in which the said lighting means is advantageously totally erased at the same time. inside the device housing in its retracted position. Moreover, the object of the invention is also to provide such a device in which the possibilities of orientation of the lighting means, placed in its deployed position, are reduced compared to known devices of the prior art.

Furthermore, the device according to the invention is further characterized in that said LED lamp is connected to said annular cradle by a second hinge comprising at least one rod whose first and second ends are provided with respectively male and female connecting means. and / or females adapted to cooperate, according to an elastic assembly, respectively, for the first end, with complementary female and / or male assembly means formed on a transversely extending spacer in the vicinity of the lower edge of the annular cradle and, for the second end, with means female and / or male complementary assemblies included in the LED lamp.

In this case, said second articulation preferably comprises two identical rods, and said annular cradle comprises two spacers extending transversely to the bottom of the annular cradle symmetrically with respect to a plane perpendicular to the bottom of said housing while said LED lamp comprises a pair of female and / or male coaxial assembly means. This advantageously makes it possible to improve the mechanical strength of the assembly making it possible to extract the lighting means from the annular cradle.

According to a preferred embodiment, said male and female assembly means are respectively defined by a lug and an orifice.

The safety lighting device according to the invention is further characterized in that said through opening that comprises said face of said housing is lined internally by a ring extending on the inner side of said face, said ring being able to accommodate said annular cradle according to a free fit and one of its edges forming at least one shoulder extending around the inner wall of said through opening, on which shoulder is adapted to rest a flange extending around the upper edge of the annular cradle.

Advantageously, said ring and said annular cradle can also comprise means for indexing and locking in position of their relative position.

In this case, said ring may comprise a toothed zone extending over at least a portion of its circumference, on its internal face, while said annular cradle has a toothed zone formed in a complementary manner on its external face.

10A, 10B, and Figure 12 shows a view of an assembly comprising three associated safety lighting devices of Figure 1, fixed against a vertical wall, and in which each respective LED lamp is in a deployed position and oriented in a given direction.

With reference to the figures, the safety lighting device 1 according to the invention comprises a housing 2, for example of parallelepipedal shape, having a bottom delimited by a peripheral wall 4 and separated by means of a transverse partition 40, in first and second compartments 30, 31 (see Fig. 2). The bottom 3 is provided capable of being clipped onto a base 5, itself intended to be fixed on any support, such as in particular a vertical partition, a ceiling, a beam, etc., by appropriate assembly means. The housing 2 also comprises a front face 7 covering the bottom 3 and having a first and a second portion 70, 71 for closing respectively the compartments 30, 31 of the bottom 3.

In the illustrated embodiment, the safety lighting device 1 comprises an LED lamp 6, having a base 60 of substantially annular shape, for example aluminum, on which can be connected one or more LEDs (not shown). The base 60 is provided with a radiator 61, allowing a dissipation of the heat generated by said LEDs during their operation, and is covered by a window 62 behind which extend said LEDs and able to diffuse their lighting. The LED lamp 6 also comprises a tab 65 integral with its window 62 and allowing its gripping and thus easy handling by an operator.

Conventionally, the LED lamp 6 is adapted to be connected via a junction box 12 disposed in the base 5, to a home electrical network or to an accumulator of electric batteries (not shown) that can be received in the compartment 31 the bottom 3 of the housing 2. An electronic card 13 makes it possible in particular to manage the supply of the LED lamp 6, and to switch it between the electrical network and said battery accumulator. The electronic card 13 also makes it possible to test the state of charge of the accumulator and to emit a light signal 14, representative of said state of charge, displayed on the portion 71 of the front face 7 of the case 2 and therefore immediately visible by an operator.

According to the invention, the LED lamp 6 is connected to an annular cradle 8 housed in the compartment 30, by means of a first and a second articulation 9, 10 allowing it to be movable between a retracted position ( Fig. 1) and an extended position (Fig. 12). The annular cradle 8 comprises a peripheral wall 82 having an upper edge 84 and a lower edge 85 and internally defines a housing 86 of substantially complementary shape to the base 60 of the LED lamp 6. In its retracted position, the LED lamp 6 is housed in the housing 86, while its window 62 advantageously extends flush with the front face 7 of the housing 2, in a through opening 72 that includes the portion 70 of said front face 7.

In fact, the first hinge 9 comprises a stirrup (FIG 4), preferably made of an elastic material, having two symmetrical arms 90, interconnected by a junction zone 91. The free ends 92 of the two arms 90 each comprise a orifice 93 for the passage of a screw 94 allowing their fixing on either side of the radiator 61 of the LED lamp 6, which comprises for this purpose two coaxial holes 63. Furthermore, the stirrup 9 comprises, on its external face 95, a pair of coaxial lugs 96, extending on either side of the junction zone 91. The two lugs 96 are provided capable of being clipped into coaxial orifices 80 that includes the peripheral wall 82 of the annular cradle 8.

The second articulation 10 (see FIG 5) comprises a pair of identical rods 11, preferably made of an elastic material, the first and second ends 110, 111 of which are each provided with a lug 112, 113 extending into opposite directions and defining planned clip heads capable of cooperating, according to an elastic assembly, respectively with the annular cradle 8 and with the LED lamp 6. For this purpose, the annular cradle 8 comprises two spacers 83 extending transversely inside the annular cradle 8, near its lower edge 85. The two spacers 83 are symmetrical with respect to a plane perpendicular to the edge 85 and each comprise an orifice 81 adapted to receive the lug 112 of a rod 11. Furthermore, the radiator 61 of the LED lamp 6 has two coaxial orifices 64 (see FIG 7, a visible hole 64) adapted to receive each other lug 113 of a connecting rod 11.

With such a configuration, the LED lamp 6 when connected, by means of the first and second hinges 9, 10, the annular cradle 8, itself placed in the compartment 30 at the rear of the front face 7 of the housing, is pivotable about four axes XI, X2, X3, X4 parallel to the front face 7 of the housing 2.

Furthermore, in accordance with the invention, the through opening 72 that includes the portion 70 of the front face 7 of the housing 2 is internally lined by a ring 73 (see FIG 10B), extending on the inner side 74 of said portion 70, and adapted to accommodate the annular cradle 8 in a free fit. In fact, the annular cradle 8, in which the LED lamp 6 has been previously fixed by means of the articulations 9, 10, is able to be inserted in the ring 73, passing through the through opening 72 from the front face. 7 When the annular cradle 8 is suitably inserted into the ring 73, a flange 87, extending around its upper edge 84, abuts a first shoulder 75 (see Fig. 10B) extending around the inner wall 76 of the through opening 72. With such a configuration, the annular cradle is rotatably mounted about an axis X5, perpendicular to the front face 7 of the housing 2, relative to the ring 73. and therefore with respect to said front face 7.

According to another characteristic of the device 1 according to the invention, the inner wall 76 of the through opening 72 comprises a second shoulder 77 (see FIG 10B) extending between the first shoulder 75 and the outer side 78 of the face before 7 of the housing 2 on which is able to rest the base 60 of the LED lamp 6 covered with the pane 62 when it is housed in the housing 86 defined by the annular cradle 8.

In the illustrated embodiment, the ring 73 further comprises a toothed zone 79 extending over its entire circumference, on its inner face 730, while the annular cradle 8 comprises a toothed zone 88 formed in a complementary manner on its outer face 89 (see Figs 3A, 10A, 10B). The toothed zones 79, 88 define indexing and locking means in position of the relative position of the annular cradle 8 with respect to the ring 73, and consequently allow fine adjustment of the angular position of the annular cradle 8 and therefore of the LED lamp 6 with respect to a plane perpendicular to the front face 7 of the housing 2.

In fact, the first and second joints 9, 10 allow the extraction of the LED lamp 6 from its housing 86, to place it by means of the tab 65, in the extended position outside the housing 2, after which it has passed through the through opening 72. In the fully extended position, the inclination of the LED lamp 6 can be changed at will by pivoting said LED lamp 6 about the axes X3, X4. In addition, its orientation can be changed by rotating the annular cradle 8 relative to the front face 7 of the housing 2 in the ring 73, so as to diffuse its lighting to the desired direction.

In the example illustrated in FIG. 12, three devices 1 according to the invention have been associated to form an assembly 100 in which the respective LED lamps 6 of each housing 2 can be oriented independently of one another towards a given direction which advantageously allows to diffuse lighting towards a larger surface.

Of course, the LED lamp 6 once deployed can be replaced in its retracted position by soliciting the joints 9, 10 that is rotated in the opposite direction. It should also be noted that many modifications can be made to the examples described above without departing from the scope of the present invention.
