Patent

CA 2494689

The invention relates to a flat lamp (1) consisting of at least two parallel glass substrates (2, 3) defining an inner gas-filled space (10) therebetween and two electrodes (4, 5) which are disposed outside the aforementioned inner space (10) and which are associated with the glass substrates. According to the invention, the inner surface (22, 32) of at least one substrate (2, 3) is coated with a phosphor material (6, 7), said surface facing the above-mentioned inner space (10). The invention is characterised in that at least one of the electrodes (4, 5) is covered with at least one preferably-transparent electrical insulator (2, 3; 14, 16; 15, 17) which can comprise at least one of the glass substrates (2, 3) or be connected to at least one of said glass substrates (2, 3).

Lampe plane (1) comprenant au moins deux substrats verriers (2, 3) maintenus parallèles entre eux délimitant un espace interne (10) rempli de gaz, comprenant deux éléctrodes (4, 5) associés aux substrats verriers et en dehors de l'espace interne (10), dans laquelle la face interne (22, 32) d'au moins un substrat (2, 3) tournée vers ledit espace interne (10) est revêtue d'un matériau luminophore (6, 7), caractérisée en ce qu' au moins une des électrodes (4, 5) est recouverte d'au moins un isolant électrique (2, 3; 14, 16; 15, 17), de préférence transparent, qui peut être constitué par au moins un des substrats verriers (2, 3) ou être associé à au moins un des substrats verriers (2, 3).
