Description

Waterproof lighting module and interchangeably mounted with different light diffusers

The present invention relates to a lighting module, to a lamp comprising such a lighting module and to a lighting system comprising said lighting module and a plurality of light diffusers.

There is a need to benefit from lighting modules that are easy to move and transport, lightweight, shock-resistant and a moist outdoor environment, or even water, resistant to cold, which only energy, which are safe for use by children and provide multiple light effects.

There is also a need to allow the same module to be used interchangeably with different light diffusers, so that a plurality of lamps can be made by changing only the light diffuser.

The invention aims to meet all or part of these needs and it achieves this through a lighting module comprising: at least one light source and at least one autonomous source of electrical energy supplying the light source (s) and contained in a compartment mounted on the lighting module, characterized in that the lighting module comprises sealing means configured to isolate the light source (s) and the independent electric energy source (s) of the light source. outside the module.

The term "autonomous electric energy source" means a source of electrical energy that is not wired loosely to an electrical network when it electrically supplies the light source or sources. Due to the presence of such an autonomous source of electrical energy, the lighting module according to the invention can be used wirelessly, which can facilitate its movement, its transport, or its installation in certain locations.

The sealing means allow the module to be used both inside a room, for example to make interior decorations, toys or night lights for children, as outside the room, for example to make garden lamps or outdoor decorations. The lighting module can also float on the water or be immersed in water, for example to make lamps or pool toys or boat lights.

The module is advantageously made at least partly of a plastic material. This plastic material is advantageously resistant to shocks and wear of time, being for example acrylonitrile butadiene styrene (ABS) but the invention is not limited to a module made at least in part of ABS.

The compartment containing the autonomous source (s) of electrical energy is advantageously removably mounted on the module. This compartment is for example fixed by snapping or screwing on the module. Such a removable compartment makes it easy to replace and / or recharge the autonomous power source (s) contained in the compartment.

The compartment containing the autonomous source (s) of electrical energy is advantageously received in a housing of the module comprising a seal against which the wall of the compartment can be applied, so as to seal the compartment.

The lighting module advantageously comprises an attached cover to diffuse the light emitted by the light source or sources.

The cover is advantageously glued on the module, which makes it possible to seal the module. In a variant, the module comprises a neck on which the cover is screwed.

The bonnet is advantageously seed, for example seed directly during its manufacture by injection into a specific mold. A seed cover makes it possible, for example, to increase the power of the light emitted by the light source (s), to improve the diffusion of this light and also to mask a user inside the module. The lighting module advantageously comprises a user interface for controlling a mode of operation of the module. This user interface advantageously comprises one or more buttons operable by a user and located for example under the module. These buttons are for example made directly by injection on a part of the module and by overmolding on said part. Such a button manufacturing method advantageously makes it possible to ensure a waterproofness of the lighting module at the buttons of the user interface and to obtain buttons of great resistance.

The module can also be configured to cooperate with a remote control, independently or in addition, the presence of the user interface on the lighting module.

The autonomous electrical energy source or sources are advantageously rechargeable batteries, batteries or solar collectors comprising photovoltaic cells carried by the module or by a diffuser on which the module is fixed. When the autonomous power source or sources are rechargeable batteries, the compartment may comprise means for recharging the battery or batteries when they are arranged inside the compartment. The compartment comprises for example a lower part comprising a housing opening towards the outside of the module and receiving one end of electrical charge connectors connected at their other end to the rechargeable battery or batteries when they are arranged in the compartment, which can to avoid having to remove and then reintroduce the batteries in the compartment to recharge them. The compartment advantageously comprises a cap attached to the lower part of the compartment and configured to seal the housing receiving one end of the electrical load connectors. The cap may allow, in the absence of recharging batteries, to seal the housing formed in the lower part of the compartment.

The battery (s) may be recharged at a charging station having electrical connectors inserted into the housing in the lower portion of the compartment to contact the charging connectors of the module.

Alternatively, the battery or batteries are recharged via a charging station configured to perform an electromagnetic induction charging, which avoids having to accurately position the lighting module on the station to ensure that their respective connectors come into contact and, avoiding any physical contact between the lighting module and the charging station, can be particularly suitable for cases where the lighting module is wet. Alternatively, the self-contained electrical energy source (s) are received in a housing of the compartment opening outwards and closed by a retractable lid, which can make it possible to extract the autonomous electrical energy source (s) of the compartment so as to replace or recharge them in an external device to the lighting module.

The retractable lid is for example snapped or screwed on the compartment. The lighting module may comprise a seal against which the cover is applied when it closes the housing of the compartment receiving the autonomous energy source or sources. The light sources are advantageously light emitting diodes

(LEDs).

The lighting module comprises for example a printed circuit at which a first subset of light sources is arranged and a second subset of light sources, whose cardinal is for example between one and six, is for example worn. by rods protruding above the printed circuit board. When the light sources of this second subset generate light, the lighting module can look like a candle, which can have a playful effect.

The stems can be slid, so that a user can adjust their height. In a variant, the module comprises only a single light source carried by a rod projecting from the top of the printed circuit.

At least two of the light sources advantageously differ in the color of the light they generate, in their shape, in their angle of aperture and / or in their power, which can make it possible to obtain different light effects from the light. module help.

The module advantageously comprises at least one electronic card for varying the intensity of illumination of the light source or sources, their duration of ignition and / or a sequence of ignition of the light sources, for example, according to several modes of operation. of the lighting module. Another subject of the invention, according to another of its aspects, is a lamp, also called a "lighting assembly", comprising a lighting module as defined above and one or more diffusers, the lighting module being at least partially received in the diffuser or in one of the diffusers and the lighting module being fixed on said diffuser removably.

Instead, we will speak of a "lamp" when the lighting assembly has only one diffuser and a lighting module and rather "lighting assembly" when there are several diffusers and a lighting module. within the set.

The lighting module is advantageously fixed on the diffuser by snapping or screwing, which can allow easy attachment by a user.

The lamp advantageously comprises at least one sealing ring interposed between the module and the diffuser when the module is fixed on the diffuser, which makes it possible to obtain a lamp having a satisfactory seal.

The lighting module is for example entirely disposed inside the diffuser when it is fixed on the diffuser, so that the module is not in contact with the ground, if the lamp thus produced is placed on the ground.

The invention further relates, in another of its aspects, to a lighting assembly comprising a lighting module as defined above and a plurality of diffusers adapted to receive said module interchangeably. A lighting assembly according to the invention is modular, which allows for example a user to obtain different lamps using a same lighting module by fixing this module to one of the diffusers of the set of lighting. Other advantages and properties of the invention will appear on reading the following description of nonlimiting exemplary embodiments with reference to the appended drawing in which: FIG. 1 represents an example of an assembled lighting module, FIG. 2 is a diagrammatic representation of the module of FIG. 1; FIG. 3 schematically represents the operation of the electronic card of the module according to an exemplary implementation of the invention; FIGS. 4 to 9 represent a module of FIG. lighting according to a first example of implementation of the invention, Figure 10 shows a lighting module according to Figures 4 to 9 and a charging station, Figures 11 and 12 show a lighting module according to a second example implementation of the invention, FIGS. 13 and 14 show an illumination module according to a third example of implementation of the invention, FIG. 15 represents a lighting module according to a fourth example of implementation of the invention, FIGS. 19 show examples of lamps obtained by fixing a module as described above on a diffuser and, Figure 20 shows a charging station according to another embodiment of the invention.

FIGS. 1 and 2 show a lighting module 1 according to the invention. This lighting module 1 comprises in the example described a hood 2 and a base

3, the cover 2 being for example fixed on the base 3 by gluing. Alternatively, the base 3 comprises a neck on which the cover 2 is screwed.

The lighting module 1 also comprises one or more autonomous electrical energy sources 4 which are, for example, rechargeable batteries or batteries and which are received in the base 3.

The cover 2 is advantageously seeded and can be made by injection of different colors. The cover 2 covers a plurality of light sources 5 not shown in Figure 1. In the example described, these light sources are light emitting diodes (LEDs) which are arranged at a printed circuit board 6. The lighting module for example comprises between one and sixty LEDs each having a power between 0.3 and 4W. Each LED is for example chosen to have a lifetime of between 50,000 and 70,000 hours.

The LEDs 5 can be placed on the printed circuit board 6 so as to illuminate upwards when the lighting module 1 rests with its base 3 on a flat horizontal surface.

The LEDs 5 may alternatively be placed under the printed circuit, so as to illuminate downwards, which may make it possible to avoid the presence of shadow areas in the scattered light. The LEDs can have two subgroups that differ from each other in the shape of the LEDs, their angle of aperture, the color of the light generated or the intensity of the lighting. The lighting module 1 comprises for example between ten and thirty white LEDs and between five and twenty RGB LEDs (RGB). Module 1 can generate white light with white LEDs or RGB LEDs.

The lighting module 1 comprises for example an electronic card 7 for controlling the module according to different modes of operation, so as to obtain a large number of light effects.

The electronic card 7 can control the LEDs 5 so that they produce a light according to predefined colors during the manufacture of lighting module 1.

The electronic card 7 can also control the LEDs so that the light generated by them mixes randomly, to obtain a large number of different colors.

The electronic card 7 can also control the LEDs 5 so that the light produced by the lighting module 1 varies randomly.

Alternatively, the user may have previously stored in a memory of the lighting module 1 one or more of its preferred hues and the electronic card 7 is arranged to control the LEDs 5 so that this or these hues are obtained.

The electronic board can also be configured to control the LEDs 5 so as to generate a dimmer effect, i.e. to raise and lower the light. The electronic card 7 can also be configured to generate with the aid of the lighting module 1 a strobe effect or a flashing and flickering effect.

FIG. 3 shows an example of operation of the electronic card 7. In the example described, the lighting module 1 is controllable via a user interface which comprises two actuable buttons, one of the function buttons sequentially represented by the "color key" table of Figure 3 and the other button operating in a sequence corresponding to the "white key" table

In the example described, eight shades were predefined during the manufacture of the lighting module 1 and the user has recorded a preferred shade in the memory of the module 1 but the invention is not limited to a particular number of preset hues and favorite hues recorded. When the user first presses the button associated with the "color key" table, he can define a color. When pressed again, the module illuminates in one of eight preset tones. At the tenth press of the button, the light is generated by the module randomly. At the eleventh support, the module illuminates according to the favorite shade of the user stored in the memory. At the twelfth support, the lighting module 1 produces a particular lighting, for example similar to that of a candle. Finally, by pressing a thirteenth time, the user turns off the lighting module 1.

When it first presses the button associated with the "white key" board, the module illuminates in white light with maximum intensity. When the user presses the button a second time, the illumination intensity is, for example, halved. By pressing a third time, the intensity of illumination is further reduced, being for example equal to 30% of the maximum intensity. Finally, by pressing the key a fourth time, the user turns off the lighting module.

The lighting module 1 may also comprise at least one of the following sensors 8: a sensor sensitive to external light, which may allow to trigger, interrupt or vary the lighting by the module according to the external brightness, a tilt sensor, which can detect the tilt of the lighting module 1, a sensor sensitive to shocks, which can allow to illuminate or interrupt lighting by the module 1 by typing on the latter, a presence sensor perceiving a movement near the lighting module 1, - a sensor detecting a music near the module, which can allow to change the lighting in time with the music, a noise sensor detecting the simulation of a blowing generated by the user, which can make it possible to turn on or off the lighting source or sources according to this blowing. This or these sensors 8 communicate for example with the electronic card 7. A first example of a lighting module 1 will now be described with reference to FIGS. 4 to 9. In FIGS. 4 to 9, the cover 2 of the lighting module 1 is not shown.

As can be seen in Figure 4, the base 3 may comprise rods 10 distributed angularly around its periphery, these rods supporting the printed circuit 6. The base 3 may also include a housing 12 whose role will be described later.

The LEDs 5 are in the example of FIG. 4 positioned on the printed circuit board 6.

In the example of FIG. 5, metal rods 14 protrude from a distance of between 2 and 10 cm, for example 4 cm, above the printed circuit 6 and carry, at their upper end, LEDs 5. The rods 14 may be arranged so that their height is adjustable. In the illustrated example, between one and six LEDs are thus raised relative to the printed circuit board 6.

In the example shown in FIG. 6, the lighting module 1 has only one white or RGB LED mounted on a rod 14.

Figure 7 is a bottom view of the lighting module 1 shown in Figure 4.

As shown, the housing 12 opens on a bottom wall 13 of the base 3 on which the lighting module 1 rests, when it is placed on a horizontal flat surface. One or more buttons 15 constituting a user interface are formed on this bottom wall 13. This or these buttons 15 are for example made by direct injection on the base 3 and are overmolded on the base 3 and act on the electronic card 7, as described with reference to FIG.

In the example shown in Figure 7, the bottom wall 13 further comprises two cavities 16 for receiving magnets. These magnets can easily fix the lighting module 1 directly on equipment, such as garden equipment such as a barbecue, or on any metal wall, to use the lighting module 1 as a lamp. extra. The magnet or magnets may also allow to fix the lighting module to an articulated arm also provided with magnets and itself attached to a device. When the light module is used in water, the magnets can cooperate with a magnetized cable, so as to hold the light module within a certain area.

The housing 12 is in the example described formed substantially in a middle portion of the bottom wall 13 but the invention is not limited to a precise positioning of the housing 12 relative to the bottom wall 13. The housing 12 comprises, as can be seen in the example illustrated, a first portion 18 having in section two right lateral faces and two rounded end faces and opens outwardly of the housing 12. The housing 12 further comprises a second portion 19 formed in the bottom of the first part 18 and opening on the latter. The second part 19 presents in the example described a rectangular section. The first and second portions are separated by a groove 20 extending around the entire periphery of the second portion 19, which groove is configured to receive a seal. FIG. 8 shows an example of a compartment 22 intended to be received in the housing 12. This compartment 22 comprises in the example described an upper part 23, in the form of a rectangular box, intended to be received in the second portion 19 of the housing 12, and a lower portion 24 to be received in the first portion 18 of the housing 12. Stand-alone electrical energy sources to be loaded without being extracted from the compartment 22, for example lithium-ion batteries -polymers, for example, are housed in the upper part 23 of the compartment 22. The set of batteries allows for example to have a power between 250 mAh and 6000 mAh, in particular between 850 mAh and 4000 mAh. The compartment 22 is for example made of ABS and may include fire protection means to protect the battery from heat sources, moisture and any contact with the outside.

As can be seen in FIG. 8, the compartment 22 may comprise load connectors 25 extending between the upper part 23 and the lower part 24 of the compartment 22. These load connectors 25 comprise, for example, a first end that is not shown and connected to the rechargeable battery (s). FIG. 9 shows an example of a base on which the compartment 22 is fixed. The compartment 22 is in the illustrated example snapped into the housing 12, which can be removed from the housing 12 if necessary.

When the compartment 22 is received in the housing 12, it is applied against the seal received in the groove 20, making it possible to seal inside the second part 19 of the housing receiving the source or sources electrical energy of the upper portion 23 of the compartment 22.

Complementary fastening means of the compartment 22 in the housing 12 may be provided. Holes are for example formed at the four corners of the first portion 18 of the housing 12 and the lower portion 24 of the compartment 22 can be screwed to the base 3 by means of screws, which are in particular screws made of stainless steel, received in each hole. Alternatively, the holes in the first part of the housing can allow the passage of cables for the suspension of the lighting module 1 to a support. As can be seen in Figure 9, two housings 28 and 29 may be formed in the wall of the lower portion 24 of the compartment 22. The housing 28 for example receives the second end of the load connectors 25 which are for example copper gold-plated so that it can withstand a humid environment. In the example shown, the housing 28 is closed by a cap 30. This cap 30 is for example made of silicone and fixed on the wall of the lower part 24 of the compartment via a screw 31. The attachment of the cap 30 on the part lower 24 compartment 22 allows the latter to be moved in rotation about an axis, so as to selectively close the housing 28 or the housing 29.

In the example shown in Figure 9, the battery or batteries are not recharged, so that the cap closes the housing 28 receiving the end of the load connectors 25 so that this end is protected from any scratches, the ambient humidity, or even water, especially seawater, or chemicals such as chlorine when the lighting module 1 is used in a swimming pool.

When it is desired to recharge the battery or batteries, the cap 30 is moved in rotation until it closes the housing 29, thus freeing access to the charging connectors 25. The attachment via a screw 31 of the cap 30 avoids the loss of the cap 30 during use of the lighting module 1. FIG. 10 shows an example of recharging station 33 intended to collaborate with the lighting module 1 described with reference to FIGS. 4 to 9.

When the cap 30 closes the housing 29, the lighting module 1 is for example placed on the charging station 33 so that a lug 34 carrying electrical connectors is received in the housing 28. These electrical connectors can then come into contact with the second end of the charging connectors 25, so as to recharge the rechargeable battery or batteries.

According to this first embodiment, the invention makes it possible to recharge the battery or batteries without having to extract them from the compartment 22. The charging station 33 comprises, for example, means for interrupting the charging of the battery or batteries automatically, to detect the presence of a defective rechargeable battery, detecting the presence of charge faults, measuring the voltage of the rechargeable batteries, detecting any overheating in the lighting module 1, switching off the lighting module 1 or generating mini electric pulses so as to power the rechargeable battery (s) once they have been charged.

In a variant, the charging station 33 is arranged to recharge the battery or batteries by electromagnetic induction.

Independently or in combination with what has just been described, the charging station 33 can serve as a base for the lighting module 1.

The recharging station 33 may also comprise, as shown in FIG.

20, a plurality of arms 32, which are for example distributed around the periphery of the charging station 33. These arms can facilitate centering on the charging station

33 of the lamp obtained, as described below, by fixing the lighting module 1 on a diffuser 50, especially when the diffuser 50 is bulky.

We will now describe, with reference to FIGS. 11 and 12, a lighting module 1 according to a second embodiment of the invention.

In this example, the base 3 on which the cover 2 is glued also defines a compartment comprising a housing 35 inside which several autonomous electrical energy sources 36 are received, these sources of autonomous electrical energy being in the example describes alkaline AA batteries or nickel-hydride batteries (Nimh) to be recharged outside the lighting module 1 via an external charging station not shown.

Two buttons 15 similar to those described with reference to Figure 7 are in the example described formed on the bottom wall 13 of the base 3. The lighting module 1 shown in Figures 11 and 12 further comprises in the example described a retractable lid 37, which is intended to seal the lower end of the housing 35. This lid is for example snapped onto the bottom wall 9 of the base 3 with the interposition of a seal, and can also be maintained via stainless steel screws on the bottom wall 9 of the base 3, similarly to what has been described with reference to FIG. 9

A cavity 38 may also be formed in the cover 37, for example in the center of the latter, so as to cooperate with the pin 34 of the charging station 33, which allows to use this charging station 33 as a base when the stand-alone electrical energy sources of the lighting module 1 are not rechargeable or must be extracted from the lighting module 1 to be recharged.

Unrepresented magnets may be housed inside the lighting module 1 which has just been described.

FIGS. 13 and 14 show a lighting module 1 according to a third embodiment of the invention. In this example, the lighting module 1 has a reduced size and a flattened shape compared to the modules described with reference to FIGS. 4 to 12.

The at least one stand-alone source of electrical energy is for example AAA alkaline batteries or Nimh batteries recharged via an external charging station and they are received in a compartment 40 supported by the base 41. The compartment 40 comprises in the example described an upper part receiving the sources of autonomous electrical energy and a lower part screwed on the upper part with the interposition of a seal.

One or more magnets not shown can be arranged in the lighting module 1. The lighting module 1 comprises for example between one and ten white or colored LEDs having a power between 0.3 W and IW. As can be seen in FIG. 14, a semi-circular housing 43 may be formed in the wall of the cover 41, this housing 43 receiving a retractable arm 44 which, when it is deployed out of the housing 43, can be entered by a user or may allow the light module to be suspended. Two diametrically opposite holes 46 may further be formed on a side wall of the cover 41, so as to allow the passage of a cable for suspending the lighting module 1.

As can be seen, a button 15 can project on the wall of the lid 41 to allow a user to obtain one of the light effects described above, for example with reference to FIG.

FIG. 15 shows a lighting module 1 according to a fourth embodiment of the invention.

In the example described, the lighting module 1 is even more flattened than that shown in FIGS. 13 and 14. Such a module 1 does not have a cover and is particularly suitable for use in advertising objects, coasters. or to be encrusted in a coffee table for example. This lighting module comprises for example AAA batteries.

The invention is not limited to the presence of a user interface provided on the lighting module 1. In all the examples described above, the lighting module could be controlled remotely by a user with the aid of a remote control, for example operating at a frequency of 2.4 GHz and having a range of 25 to 50 meters.

We will now describe with reference to Figures 16 to 19 different examples of attachment of a module 1 as described above to a diffuser 50 to produce a lamp.

The diffuser 50 may have any shape, for example a spherical, cylindrical, ellipsoid, ovoid, pyramidal, cubic, or flying saucer, this list not being limiting

The diffuser 50 is for example hollow, defining an inner housing 51 intended to receive at least part of the lighting module 1 when the latter is fixed on the diffuser 50 and communicating with the outside of the diffuser through an opening 52. The diffuser 50 may be made of glass, polyethylene, polypropylene, polycarbonate, EVA, PVC, silicone, paper or inflatable plastic.

The diffuser 50 can be treated to resist UV and / or chlorinated waters.

The diffuser 50 may include a pigment capturing daylight and can restore it later, which can provide a phosphorescent diffuser in the dark.

In the example illustrated in FIG. 16, the lighting module 1 comprises a fixing ring 53 intended to be mounted on the base 3. The fixing ring comprises reliefs 54 projecting outwards from the ring 53. The diffuser 50 shown in FIG. 17 comprises a ring 55 having reliefs 56 complementary to those of the ring 53 and projecting towards the inside of the ring 55. This ring 55 is for example received in the opening 52.

When the lighting module 1 is introduced into the diffuser 50, the cooperation of the complementary reliefs 54 and 56 of the rings 53 and 55 allows the lighting module 1 to be removably attached to the diffuser 50.

In the example shown in FIG. 18, the fixing of the lighting module 1 on the diffuser 50 also implements two sealing rings 57 and 58, the ring 58 being for example made of ABS and the ring 57 being example made of silicone. The lighting module 1 is for example previously screwed with stainless steel screws on the rings 57 and 58.

In the example of FIG. 19, the lighting module 1, which is for example as described with reference to FIGS. 13 and 14, is received inside a ring 60, itself secured to the diffuser 50 and arranged so that the lighting module 1 can be held inside this ring 60 by snapping. The invention is not limited to the examples which have just been described, it is possible, for example, to combine characteristics described with respect to different embodiments.

The lighting module 1 described with reference to FIGS. 4 to 10 may comprise instead of the stand-alone electric power sources described rechargeable batteries on an external recharging station or batteries, as described with reference to FIGS. In variants not shown, the lighting module comprises photovoltaic cells for charging the autonomous source or sources of electrical energy.

The diffuser or diffusers 50 may be covered with an electroluminescent paper.

The lighting module 1 may include an optical system for better light distribution, such an optical system comprising for example lenses covering the light sources or reflectors.

The illumination module as described in any one of the above embodiments may be mounted by screwing, latching or by any other means within a silicone ring, floating in the water. The resulting assembly can then float hood down into the water, for example to illuminate the bottom of a pool.

The lighting module 1 may include a thermometer measuring the ambient temperature and / or an integrated mini-weather station. As a variant, this mini weather station is integrated into a remote control of the module.

The lighting module 1 may also include a load indicator of the one or more autonomous sources of electrical energy.

The invention makes it possible to fix the lighting module 1 interchangeably in a plurality of diffusers 50, making it possible to produce lamps for multiple applications such as garden lamps, Christmas decorations, lamps for the decoration of indoor or outdoor, lamps for swimming pool or even for boats. In the claims, the expression "comprising a" must be understood as "comprising at least one" unless the opposite is specified.
