An spherical lighting

The invention relates to a lighting device comprising: - a light source (3), capable of emitting light in a cone of light; - an electronic circuit (5) for controlling the light source, - a wall whose shape defines an enclosure (1) surrounding said light source (3) and the electronic circuit (5), said wall comprising at least one scattering material light, the surface of which comprises a first zone, corresponding to the intersection with the light cone, and a second region complementary to the first region; - the electronic circuit (5) being disposed in a first portion, said top, of the chamber, the cone of light being emitted from the light source (3) to a second part, said bottom of the enclosure (1) and - a diffuser (9), comprising a light scattering material disposed within the enclosure, between the light source and said first zone, the diffuser being adapted to direct a portion of light, backscatter, to said second region of the chamber surface.
