PURPOSE:To reduce the strain of glass members which touch struts by providing the inner walls of opposed plates of a plate-like electric lamp with a proper number of projections with suitable shapes, and forming each pair of projections into the strut. CONSTITUTION:The symbols 1 and 1' represent the upper and the lower plates of the tubular body of a plate-like electric lamp, and the symbols 2 and 2' represent the inner walls of the plates 1 and 1', respectively. The symbols 3, 3'-8, 8' represent struts protruding from the plates 1 and 1'; the symbol 9, an adhesive; and the symbols 10 and 10', cylindrical struts protruding from the plates 1 and 1'. Here, etch pair of struts are simply made in contact with one another, simply made in contact with one another with a phosphor interposed between them, stuck with an adhesive, unified together with an adhesive consisting of a phosphor and an adhesive, or fused together into a strut. The symbols 11 and 11' represent electrodes. The symbol 12 represents a device which supports the electrodes 11 and 11'. The symbol 13 represents a part at which the peripheries 14 and 14' of the upper and the lower plates 1 and 1' are fused together. Owing to its structure illustrated in the figure, a thin-type electric lamp having an almost flat curved surface with a wide area can be made easily. Besides, since each pair of projections are formed into a strut by making them in contact with one another, the lamp resists atmospheric pressure satisfactorily, and hardly breaks. |
