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. According to the invention, at least part of the intermediate organic glass substrate (105) is arranged to deflect the light out of the plane of the panel and through at least one of the first and second glass substrates to provide a diffused light output.
