Problems solved by technology

In addition, when the coil size of the triple coil is too large, the electrodes cannot be installed in the luminous tube. Therefore, the number of turns of the third winding of the double coil 205 wound on the third core wire 206 is usually limited to about 1 turn.
Therefore, as shown in FIG. 10(c), the three-time winding hollow portion 206′ where the three-time core wire 206 has existed has a short dimension in the direction of the winding axis, and the electron-emitting material cannot be contained in the three-time winding hollow portion 206′. remain stable, so it is difficult to fill the three times wound hollow portion 206' with electron emission material

Embodiment Construction

[0044] Next, an electrode for a discharge lamp and a discharge lamp according to an embodiment of the present invention will be described with reference to the drawings.

[0045] 1st embodiment

[0046] Use the following Figure 1~6 The electrode for a discharge lamp and the discharge lamp according to the first embodiment will be described.

[0047] figure 1 It is a sectional view showing the discharge lamp of the first embodiment. The discharge lamp (hereinafter referred to as lamp) of the first embodiment is a bulb-shaped fluorescent lamp (12W) for replacing a general bulb (60W), and its basic structure is based on that of an existing lamp.

[0048] Such as figure 1 As shown, the lamp 1 includes an arc tube 10, a supporting resin member 30 supporting the arc tube 10, an eggplant-shaped glass outer tube bulb 31 including the arc tube 10, and a lamp integrally assembled on the supporting resin member 30. An electronic stabilizer 32 of a so-called series inverter type f...

Abstract

An electrode for a discharge lamp includes a quadruple coil (50) made by winding a filament (41) to form a single coil (44), secondarily winding the single coil (44) to form a double coil (46), tertiarily winding the double coil (46) to form a triple coil (48), and quarternarily winding the triple coil (48). An electron emitting substance is filled in at least the tertiarily wound hollow portion (47') of the quadruple coil (50). Thereby, electrodes (15, 16) for the discharge lamp having a small size and a large capacity for filling the electronic emitting substance can be obtained.

Description

field of invention [0001] The present invention relates to an electrode for a discharge lamp and a discharge lamp, and more particularly, to an electrode for a discharge lamp filled with an electron-emitting material for emitting electrons, and a discharge lamp provided with the electrode. Background technique [0002] In recent years, power saving and life extension of discharge lamps have been pursued. As one of the methods for realizing power saving, it is considered to make the light-emitting tube thinner and improve the luminous efficiency. When the light-emitting tube is thinned, the current loss and electrode loss during discharge are reduced, so the luminous efficiency is improved. [0003] On the other hand, as one of the methods for achieving a longer life, it is conceivable to increase the amount of the electron-emitting material filled in the filament coil of the electrode. Figure 9 It is a photograph showing the triple coil of the conventional example. For ex...
