Abstract: A glass panel includes a first glass substrate, a second glass substrate, a spacer profile at the periphery of the glass panel between the first and the second glass substrate. There is an intermediate substrate in the intermediate space between the first and the second glass substrates, the substrate having a first coefficient of thermal expansion, and means to maintain the intermediate substrate within the intermediate space. The panel also includes a second profile, having a second coefficient of thermal expansion, positioned facing the inner face of the spacer profile within the intermediate space between the first and second glass substrates of the glass panel. The second profile carries the means to maintain the intermediate substrate within the intermediate space. A difference between the first coefficient of thermal expansion and the second coefficient of thermal expansion is less than or equal to 20%.

Abstract: A glass lighting panel (1), comprising: a first glass substrate (101), a second glass substrate (102), a spacer profile (103) at the periphery of the glass panel (1) between the first and the second glass substrate, the spacer being used to maintain an intermediate space (104) between the first and second glass substrates, According to the invention, the panel comprises: an intermediate organic glass substrate (105), at least one light source (106). According to the invention, the spacer profile (103) comprises: means (107) to maintain the intermediate organic glass substrate (105) in the intermediate space (104) between the first and the second glass substrates, means (108) to lodge the at least one light source (106) so as the at least one light source emits light into the intermediate organic glass substrate (105) predominantly along a plane of the panel.
