Description

LIGHTING DEVICE

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a lighting device. It applies, in particular, remote monitoring of a room through a communicating portable terminal in connection with the lighting device.

STATE OF THE ART

Video surveillance of a room requires, in current systems, the addition of image capture devices in the room.

These systems have the disadvantage of not being discrete and, even in the case of their miniaturization, to require specific power and wiring. This wiring generates an additional installation cost and the implementation of skilled labor.

On the other hand, some of these surveillance systems are called "babycam" (abbreviated to "baby camera", translated into French as "camera for baby") and can monitor a young child when this child is, for example, alone in a room. Current systems have the same disadvantages as stated above.

Thus, current systems do not satisfactorily meet the conditions of:

- discretion and

- Low installation cost, both in terms of time and financial.

OBJECT OF THE INVENTION

The present invention aims to remedy all or part of these disadvantages. For this purpose, according to a first aspect, the present invention relates to a lighting device, which comprises:

a cover comprising:

a fixing means at the base and

- A cache, positioned on the path traveled by the emitted light, having a transparent portion positioned opposite the path traveled by the image sensor during a movement along the rail.

Thanks to these arrangements, the device can be attached to a bulb socket so as to be supplied with electrical energy without requiring additional wiring of the room in which this device is installed. On the other hand, this device can be made discrete depending on the chosen shape may in particular be similar to that of a traditional bulb.

In addition, the rail implemented allows optical isolation of the image sensor, which limits the impact of optical noise generated by each light source.

In embodiments, the cover comprises a second rail comprising at least one opaque wall obstructing the passage of light emitted by each light source forming a guide in displacement of the image sensor in a race complementary to the race guided by the first rail.

The advantage of these embodiments is to further limit the optical noise generated by the light sources on the image capture performed by the image sensor of the device.

In embodiments, at least a portion of a wall of the first rail and at least a portion of a wall of the second rail are positioned opposite one another.

The advantage of these embodiments is to further limit the optical noise generated by the light sources on the image capture performed by the image sensor of the device by extending the optical path between each light source and the image sensor.

In embodiments, the device that is the subject of the present invention comprises an opaque mobile cover, attached to at least one mechanical element, obstructing the passage of light, from each light source towards the image sensor, close to the element mechanical.

The advantage of these embodiments is to further limit the optical noise generated by the light sources on the image capture performed by the image sensor of the device,

In embodiments, the image sensor is positioned facing at least one mechanical element attached to a moving cache.

In embodiments, the device that is the subject of the present invention comprises an additional cache, at least partially surrounding the image sensor, positioned facing the transparent part of the lid cover.

In embodiments, the first and second rails form a curved interstice, the displacement of the image sensor being at least partly rotated according to the curvature of the gap.

Furthermore, each parameter of an exemplary embodiment can be implemented independently of other parameters of said exemplary embodiment.

Note that the term "one" is used in the sense of "at least one". The term "path traversed by the image sensor 225" is the set of positions that the image sensor 225 may have along the rail 215.

It is already noted that the figures are not to scale.

FIG. 1, which is not to scale, shows a sectional view of one embodiment of the illumination device 10 of the present invention. This device 10 comprises:

a base 20 comprising:

a means 205 for fixing to a socket holder for a light bulb,

at least one light source 210,

a first rail 215, comprising at least one opaque wall 220 obstructing the passage of light emitted by each light source 210, forming a moving guide of an image sensor 225,

the image sensor 225 comprising at least one mechanical element 230 guided by the rail 215 and

a lid 30 comprising:

a means 305 for fastening to the base 20 and

a cover 310, positioned on the path traversed by the emitted light, comprising a transparent portion 315 positioned facing the path traveled by the image sensor 225 during a movement along the rail 215.

The base 20 is, for example, a housing having a housing for electronic components forming a control system (not shown) mechanical and electronic means implemented by the device 10.

The fixing means 205 to a lighting bulb socket holder is, for example, a screw or bayonet base having as function both the holding in position of the device 10 and the power supply of this device 10 .

In variants, any other type of base usually implemented by a light bulb is implemented.

An internal power supply circuit (not shown) feeds each means of the device 10 requiring electrical energy to operate, such as a motor (not shown) for moving the image sensor 225, for example.

At least one light source 210 is, for example, a monochromatic or polychromatic electroluminescent diode powered by the circuit internal power supply. Preferably, this light-emitting diode is positioned to produce a light beam oriented in a direction generally opposite to the fixing means 205.

The first rail 215 is, for example, a structure comprising an opaque wall 220, a part of the wall 220, distal from the base 20, forming a moving guide for a mechanical element 230. The wall 220 is, for example, a surface an opaque material positioned generally parallel to the main radiation angle of each light source 210. The material used may be of organic, metallic or plastic material,

This wall 220 delimits two zones:

the first zone comprises at least one light source 210 and is intended to illuminate a room in which the device 10 is positioned and

the second zone has no light source 210 and aims at limiting the exposure of the image sensor 225 to the optical noise generated by the light sources 210 of the first zone.

The first rail 215 may have a rectilinear or curved shape depending on the set of desired image sensor positions 225. Preferably, this first rail 215 has a shape of an arc having the base of origin points 20, the point of maximum distance from the rail relative to the base 20 being reached in the middle of this arc.

The image sensor 225 is, for example, a camera or a photographic sensor. This image sensor 225 is oriented towards the outside of the device 10, preferably in a direction generally opposite to the fixing means 205. This image sensor 225 is configured to capture an image in the visible or infrared light spectrum, for example.

This image sensor 225 comprises a mechanical element 230 guided by the rail 215. This mechanical element 230 is, for example, a support rod of the image sensor 225 on the rail 215.

In variants, the image sensor 225 is set in motion by a motor (not shown) controlled automatically according to the captured image or by a communicating portable terminal of a user.

In other variants, the image sensor 225 is initially oriented manually and then remains motionless without further action of a user. The automatically controlled movement, electronic or manual, is thus performed along the path defined by the first rail 215.

The cover 310 is, for example, a hemispherical surface made of a material diffusing the light rays emitted by each light source 210. Preferably, the transparency of the material used in the cover 310 is selected so that the components under the cover 310 do not not visible to the naked eye.

This cover 310 has a transparent portion 315 positioned facing the path traveled by the image sensor 225 during a movement along the rail 215. This transparent portion 315 is, for example, a slot, made in the cover 310 , covered with a transparent material for the wavelengths captured by the image sensor 225.

In variants, this transparent part corresponds to an uncovered orifice made in the cover 310 facing the path traveled by the image sensor 225.

In variants, a transparent part of the cover 310 does not cover part of the path traveled by the image sensor 225. In these variants, the image sensor 225 can be concealed during a period of non-use .

This cover 310 defines the cover 30, this cover 30 being fixed to the base 20 by the fastening means 305. This fixing means 305 is, for example, a threading complementary to a thread of the base, the cover 30 being fixed by screwing at the base 20.

In variants, this fastening means 305 is a set of clips and stops for fixing the cover 30 by pressing the cover 30 towards the base 20.

In variants, the lid 30 is fixed to the base 20 so that it can be moved in rotation relative to an axis perpendicular to a plane formed by the fasteners. This movement can be mechanical, automatic or manual, depending on an internal or external control device 10 or a manual support performed by a user.

In preferred embodiments, as shown in FIG. 1, the cover 30 comprises a second 320 rail comprising at least one opaque wall 325 obstructing the passage of light emitted by each light source 210. forming a guide in displacement of the image sensor 225 in a race complementary to the race guided by the first rail 215.

215.

The wall 325 of the second rail 320 is positioned, for example, in the plane formed by the wall 220 of the first rail 215 so as to form a displacement gap of the mechanical element 230.

In preferred variants, the wall 325 of the second rail 320 is positioned parallel to the plane formed by the wall 220 of the first rail 215 without being positioned on this plane.

The geometry of the mechanical element 230 is adapted as a function of the positioning of the walls 325 and 220 so that the mechanical element 230 bears on the rails 215 and 320.

In variants, the mechanical element 230 is not initially supported on the rails 215 and 320. In these variants, the mechanical element 230 flies over the rails 215 and 320, near these rails 215 and 320 During the wear of the device 10, the mechanical element 230 can be made to rest on one or the other of the rails, 215 or 320, so that the travel of the sensor is maintained. picture 225.

This additional cache 235 is made of an opaque material and simultaneously aims to limit the exposure of image sensor 225 to the light noise and to hide the components forming the interior of the device 10.

The dimensions of this additional cache 235 are, for example, chosen so that, in an extreme position of the displacement path of the image sensor 225, the transparent part 315 of the cover 30 makes it possible to see only the image sensor 225 and the cache additional 235.

In preferred embodiments, as shown in FIG. 1, the first and second rails, 215 and 320, form a curved interstice, the displacement of the image sensor 225 being at least partially rotated according to the curvature of the 'gap.
