Problems solved by technology

[0005] 2. Low mechanical strength
[0006] 3. Too much reliance on the technical level of melting personnel
[0007] There is also a sealing process that uses lead solder to seal between glass and metal. This type of sealing has not been widely used due to slow air leakage and low connection strength.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0023] see first figure 1 , figure 1 It is a structural diagram of glass lamp tube and metal sealing, the sealing method of glass lamp tube and metal electrode of the present invention, comprises the following steps:

[0024] ① Clean the glass lamp tube 1, cover the part that does not need to be injected, place it in the ion implanter, and inject the active metal ion layer 2 on the surface of the glass lamp tube 1;

[0025] ②Plating a layer of metal film 3 outside the metal ion layer 2 of the glass lamp tube 1;

[0026] ③ The solder material 4 , the glass lamp tube 1 and the metal electrode assembly 5 are sealed together by a high-temperature brazing process.

[0027] Below is an embodiment, and concrete implementation method is as follows:

[0028] This embodiment is t...

Abstract

The invention discloses a method for sealing a glass lamp tube and a metal electrode. The method includes the following steps that firstly, a metal ionic layer is implanted on the surface of the glass lamp tube; secondly, a layer of metal film is plated; thirdly, the glass lamp tube and the metal electrode are combined into a whole in a sealing mode through the high-temperature brazing technology with soldering flux. A lamp manufactured with the method has good mechanical strength and air tightness and is suitable for standard batch production.

Description

technical field [0001] The invention relates to an electric light source, in particular to a method for sealing a glass lamp tube and a metal. Background technique [0002] At present, the methods of glass tube and metal sealing for electric light source lamp mainly include: transition glass sealing method and lead solder connection method. [0003] The transition glass connection method is a method of connecting and sealing the metal electrode and the glass lamp tube through one or more glasses with different expansion coefficients. This method solves the connection problem between glass and metal through the step-by-step transition of expansion coefficient. This sealing technology has good airtightness and long product life. But there are following deficiencies: [0004] 1. The manufacturing process is complicated and the efficiency is low. First solve the sealing of glass and metal, and then connect with quartz glass through transition glass. Between the glass connecte...
