である。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a small DC discharge lamp. [Prior Art] Conventionally, in a DC discharge lamp, for example, as shown in Fig. 2,
Generally, the anode was placed between the cathode and the stem glass. According to this structure, for example, if a plate-shaped anode plate was used as the anode, it would be very difficult to attach the anode plate by welding, etc., because there are glass stems and cathodes on both sides of the anode (No. Figure 3). Incidentally, related lamps of this type include, for example, Japanese Unexamined Patent Publication No. 58-42158, Japanese Utility Model Application No. 57-180967, and Japanese Utility Model Application No. 61-1724.
Examples include No. 58. (Problems to be Solved by the Invention) The present invention has been made for the purpose of providing a new horizontal electrode arrangement in a discharge lamp and overcoming the above-mentioned conventional difficulties in workability. ( Means for Solving illIM1] That is, in the present invention, the anode plate is not placed in the narrow space between the glass stem and the cathode, but is placed over the cathode and on the side of the light emitting device. This solves the problem.

11に電圧が印加されて放゛市灯6が点灯される。(Function) Although the distance between the anode plate and the cathode is short, there is a wide space on the opposite side of the anode, and the welding rod can be easily inserted, making the manufacturing work extremely simple. An example will be explained according to the drawings. Fig. 1 is a diagram showing the main parts of a discharge lamp according to an embodiment with a part cut out.
An anode plate 1 is connected to an anode lead wire 2 to constitute an anode 3, and a cathode 4 coated with a thermionic emitting material or the like is fixed to a three-pole lead wire 5. The discharge lamp 6 is connected to the anode lead wire 2
, a glass stem 7 for supporting and fixing the cathode lead wire 5, an outer tube glass 8, a phosphor 9, an enclosure 1. When a voltage is applied to the power source 11, the street light 6 is turned on.

2, the anode lead wire 2 was lengthened in advance and the anode plate 1 was positioned between the cathode 4 and the front light emitting surface 13 of the discharge lamp. During the welding operation, the welding electrode rod 14 shown in FIG. 5 can easily grasp both, and a highly reliable discharge lamp can be manufactured.
第2図,第3図は従来の構造による溶接作業方法であり
、溶接電極棒14と陰極4がぶつかる樋造であり、作業
がきわめて困難であった。FIGS. 2 and 3 show a welding work method using a conventional structure, in which the welding electrode rod 14 and the cathode 4 collide with each other, making the work extremely difficult.
