- the radius of curvature of the portion 9b is preferably lower than that of the portion 9a.
- the portion 9c of the diffuser 9, forming a convergent lens, is intended to capture and focus the light rays. Part 9c converges a portion of the light rays to the upper part of the globe to illuminate this area of the globe.
- the diffuser 9 makes it possible to direct part of the light of the cone of light emitted by the light source towards the second zone of the surface of the globe (complementary to the first zone of intersection of the cone of light and the globe).
- the Globe material 1 itself makes it possible to homogenize the illumination of the globe over its entire surface, in the first and second zones.
- the support of the light source may be covered at least in part with a white coating, for example a white varnish.
- a white coating for example a white varnish.
- the part 9a corresponding to a diverging lens, has for example a radius of curvature of the order of 55 mm;

- the diffuser 9 may comprise the parts 9a and 9b, but not the parts 9c and 9d.
- the different parts of the diffuser 9 may be provided with facets in order to better redistribute the light rays to the different areas of the globe.
- FIG. 6 represents a calculated light energy distribution in a plane of symmetry of the globe parallel to the z axis (corresponding to the section plane of FIG. 2).
- the calculations were made for a lighting device comprising a globe 101, an electronic card disposed inside the globe, serving as a support for an LED, and a diffuser 109 of the type illustrated in FIG. 3, surrounding the LED. and the electronic card.
- the main direction of the light emission of the LED corresponds to the z axis. The LED emits light downwards.
- the globe itself thanks to the choice of a material diffusing the light, makes it possible to homogenize the lighting of the globe (the material specifically chosen for the globe has not been taken into account in the modeling).
- Another advantage of such a lighting device is related to the fact that the diffuser constitutes a resonance cage for the light rays. This maximizes the light energy emitted by the lighting device.
- Another advantage of such a lighting device is related to the fact that the diffuser makes it possible to position and hold in place the constituent elements of the control circuit in the globe.
- FIG. 1 Another advantage of a lighting device of the type described in connection with FIG. 1 is that the use of a diffuser inside the globe makes it possible to use only one source of light. This makes it easier to control the light intensity and the color of the globe lighting.
- the inventor further proposes to produce a lighting system comprising a set of lighting devices (or globes or luminous spheres) such as that described with reference to FIG.
- a lighting system comprises for example at least 1000 globes or light spheres, for example arranged in a matrix of 32 lines and 32 columns.
- the luminous spheres can be connected by wires to a ceiling lamp.
- Such a lighting system makes it possible to control the movement (for example vertical), the luminous intensity and / or the color of each luminous sphere (or "pixel") independently of the other luminous spheres.
