[0027] Next, a discharge lamp according to an embodiment of the present invention will be described with reference to the drawings. figure 1 It is a figure for demonstrating the discharge lamp which concerns on 1st Embodiment of this invention.

[0028] The main part of the discharge lamp of this embodiment is comprised by the glass envelope 1 which consists of hard glass, such as borosilicate glass. A discharge space 11 is formed inside the glass envelope 1 , and a rare gas composed of a mixed gas of neon Ne and argon Ar and mercury Hg are sealed in the discharge space 11 . In addition, on the inner surface of the glass envelope 1, a phosphor layer 2 made of, for example, RGB three-wavelength phosphors is formed.

[0029] Metal terminals 3 are formed at both ends of the glass bulb 1 as power supply terminals for supplying power to the lamp. The metal terminal 3 is composed of a metal body 31 and a solder layer 32 .

[0030] The metal body 31 is a cylindrical metal with do...

Abstract

The invention provides a discharge lamp with uneasily damaged glass shell and a manufacturing method thereof. The discharge lamp comprises a glass shell (1), a metal body (31) covered on the glass shell (1) and a solder layer (32) between the metal body (31) and the glass shell (1). The glass shell (1) and the solder layer (32) are not fixedly connected. Compressing deformation alpha caused by the metal body (31) is formed in the circumferential direction of the glass shell (1). Stress value of the compressing deformation alpha is 6kgf / cm<2>, ideally less than 40kgf / cm<2>.

Description

technical field [0001] The present invention relates to a discharge lamp used as a backlight light source of a liquid crystal television or a personal computer, and the like. Background technique [0002] In recent years, as a light source used in a liquid crystal television or the like, an external electrode fluorescent lamp as disclosed in Japanese Patent Application Laid-Open No. 2004-146351 (hereinafter referred to as Patent Document 1) has been used. This is because these lamps can be connected mechanically and electrically only by embedding external electrodes in the fixed unit on the backlight side. Conventionally, a solder layer formed by methods such as solder dipping has been used for external electrodes. [0003] However, solder-only electrodes have problems such as low heat dissipation and easy peeling. Therefore, the invention of the discharge lamp shown in Japanese Patent Laid-Open No. 2006-40857 (hereinafter referred to as Patent Document 2) or Japanese Pate...
