Abstract: A luminous multiple glazing unit including: first and second flat glass elements; light-emitting diodes located in an internal space; a reflector including a part fixed to the glazing unit in the internal space; and a first luminous zone associated with the first glass element. In a first configuration, the reflector has a central reflective area for reflecting at least 30% of total flux emitted by the diodes in the group onto a first mechanism scattering light, or, in a second configuration, the reflector forms a beam splitter and has a double-image central reflective area of a first central area for reflecting first central rays onto a first mechanism scattering light and a second central area for reflecting second central rays onto a second scattering mechanism, the reflector reflecting at least 30% of total flux emitted by the diodes in the group.

Abstract: A lighting device includes light-emitting diodes as illuminating light sources and arranged on a support, and a receptacle housing the support of the diodes and closed by a glass substrate facing the diodes. The receptacle and the fastener to fasten the support to the receptacle, are made of a thermally conductive material. Furthermore, a scattering device to scatter light is arranged at least in zones located facing the diodes, and a reflector of light is arranged in the receptacle. The lighting device is thus thin, highly effective, and causes very little dazzle.

Abstract: The invention relates to vacuum insulating glazing consisting of two glass sheets held apart by spacers and a peripheral seal. The invention also relates to a process for producing such vacuum insulating glazing.
