Problems solved by technology

[0002] The sodium lamp uses sodium vapor discharge to produce an electric light source of visible light. When the sodium lamp is working, the arc tube of the sodium lamp will generate high temperature, forming thermal expansion stress on the arc tube and the bracket. The traditional hard connection between the arc tube and the bracket is easy to cause the arc tube to explode.

Abstract

The invention relates to a high luminous efficiency sodium lamp with a lamp anti-explosion structure. The high luminous efficiency sodium lamp with the lamp anti-explosion structure comprises a lamp head, a lamp wick, a bulb, a big support, a small support and a sodium lamp electric arc pipe, wherein the big support, the small support and the sodium lamp electric arc pipe are arranged in the bulb, the big support and the small support are respectively connected with two lamp wick leading-out ends of the lamp wick, the big support and the small support are respectively connected with electrode leading-out ends which are arranged at two ends of the sodium lamp electric arc pipe, the big support is connected with one of the electrode leading-out ends arranged at one end of the sodium lamp electric arc pipe through an elastic connecting support, the elastic connecting support is a bucking member which is formed by a horizontal section and an inclined section, the inclined section is connected with the big support, and the horizontal section is connected with the sodium lamp electric arc pipe. The high luminous efficiency sodium lamp with the lamp anti-explosion structure has the advantages that the defect of lamp tube explosion caused by thermal expansion tension of the sodium lamp is avoided due to the elastic connecting support, and thus the service life of a product is prolonged.

Description

technical field [0001] The invention relates to a high-luminous-efficiency sodium lamp with an anti-explosion lamp structure. Background technique [0002] The sodium lamp uses sodium vapor discharge to produce an electric light source of visible light. When the sodium lamp is working, the arc tube of the sodium lamp will generate high temperature, forming thermal expansion stress on the arc tube and the bracket. The traditional hard connection between the arc tube and the bracket is easy to cause the arc tube to explode. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-luminous-efficiency sodium lamp with better reliability and anti-explosion lamp structure. [0004] The technical solution adopted by the present invention to solve its technical problems is: a high-luminous-efficiency sodium lamp with an anti-explosion lamp structure, including a lamp cap, a wick, a bulb, and a large bracket, a small bra...
