- a straight edge of the support comprises along its outer face an elongate housing sized to receive said elongate body of the lighting system so as to integrate the lighting system in the support in a rest position of the device.
- the lighting system when it is out of the housing, is arranged to illuminate an article placed anywhere in said space on the bottom, in a direction of illumination variable according to the orientation of the movable arm and the angle of inclination of the elongated body relative to the arm.
- the light sources are controlled by a switch mounted on a rim of the support.
- the control can be remote and controlled by a transmitter such as a remote control or a mobile phone.
- the autonomous lighting system is recharged by a power source that can be arranged in a rim of the support.
- a connector disposed on a rim of the support makes it possible to connect the power source to the electrical network, in particular to recharge batteries.
- the power source disposed in a rim of the support is a battery with a range of between 5 and 10h.
- the power source can for example be provided by simple batteries. In this case, if the batteries are not rechargeable, the presence of the connector is no longer essential.
- all the light sources give a light between 3000 and 6000 Kelvin.
- the totality of the light sources gives a light of the order of 4500 Kelvin.
- the light sources are controlled by a dimmer, giving a light of between 3000 and 6000 Kelvin. From the composition of the sources of light, results a light of 4500 Kelvin which corresponds to a neutral light or light of the north, outside looking towards the north to avoid the vision of the sun, or light of the day. The possibility of changing the color temperature makes it possible to magnify the color of certain colored gems.
- the intensity of the lighting system is ideally between 1300 and 2200 Lux.
- the lighting system comprises two hot light sources between 2500 and 3500 Kelvin and two cold light sources between 5500 and 6500 Kelvin to give a light of the order of 4500 Kelvin.
- the lighting system may comprise between 6 and 8 hot and cold light sources, for example 6, to give a light varying from 3000 to 6000 Kelvin.
- the support can be declined in several formats, such as for example a small and a large model.
- the tray may also include light sources with fixed or variable color temperature.
- the support can be made in the form of a rectangular tray whose dimensions vary according to the desired use.
- the external dimensions of the tray will be between 10 and 45 centimeters for the length, between 10 and 40 centimeters for the width, between 1 and 6 centimeters for the height of the edges and between 1 and 6 centimeters for the depth of the edges.
- the height of the flanges is at least twice and preferably at least four times smaller than the width and length of the tray.
- the support may be in the form of a polygonal plate, such as a hexagonal plate or an octagonal plate.
- the support may be in the form of a rounded plate having on a portion of its circumference a straight edge.
- FIG. perspective of a support in the form of a tray comprising, at rest, a lighting system integrated into a housing disposed in a rim;
- FIG. 2 shows a perspective view of a device comprising a tray and a lighting system extracted from a housing disposed in a flange, the lighting system being mounted on a movable and steerable arm;
- FIG. 3 represents a perspective view of a device in the form of a tray and a lighting system extracted from a housing disposed in a rim, the lighting system being mounted on a movable and steerable arm and controlled by a dimmer; and
- FIG. 4 represents a perspective view of a device in the form of a tray and a lighting system extracted from a housing arranged in a rim, the lighting system, comprising six LEDs, being mounted on an arm mobile and steerable and controlled by a dimmer.
- the portable device in the form of a square plate 1 has four flanges 3 defining a space 4 in which an article 9 is capable of being placed.
- One of the flanges 3 comprises a housing 7 ( Figure 2) for integrating a lighting system 2 when the device is not in use.
- the lighting system 2 comprises a plurality of light sources of which at least one of the light sources is a warm white light-emitting diode (LED) and at least one of the light sources is a cold white light-emitting diode.
- LED white light-emitting diode
- the elongate body 2 'housing the light sources is mounted on one end of a movable and steerable arm 10 whose other end is articulated, in this example, on an inner wall of the housing 7.
- the light sources illuminate an article 9, a precious stone in this example, placed in the space 4 delimited by the four edges 3.
- the lighting system is arranged to illuminate an article 9 placed anywhere in said space on the bottom 4, in a variable illumination orientation according to the orientation of the movable arm 10 and the angle of inclination of the elongated body 2 'relative to the arm 10.
- FIG. 1 the example illustrated in FIG.
- the arm 10 is flexible, and it can be stretchable and retractable.
- the cold white LEDs emit a cool white color of 6000 Kelvin and the warm white LEDs 6c emit a warm color that tends towards the yellow of 3000 Kelvin. It has been found that the use of these two types of LEDs and their positions relative to each other on the lighting system 2 can improve the phenomenon of scintillation and recreate a natural light of about 4500 Kelvin.
- a rectangular "large format" plate uses a larger number of light sources to illuminate the space defined by the flanges 3.
- the sources The lights are controlled by a dimmer 8, giving a light between 3000 and 6000 Kelvin.
- the external dimensions of this plate are 44 centimeters for the length, 32 centimeters for the width, 5 centimeters for the height of the edges and 4 centimeters for the depth of the edges.
