specific Embodiment approach 1

[0049] Specific implementation mode one: see Figure 1 to Figure 4 , the manufacturing method of the multi-U sodium lamp inner tube of the present embodiment, the specific steps are:

[0050]Step 1. Bending tube: According to the power of the light source to be produced, select the anti-sodium glass tube (the length of the anti-sodium glass tube required by different specifications of sodium light source lamps is different), and place the anti-sodium glass tube on the U-shaped bend On the tube machine, manually operate the button on the U-shaped tube bending machine, the anti-sodium glass tube rotates, and the flame heats the soda-resistant glass tube from the bottom. Shaped sodium-resistant glass tube 1 (see figure 1 ), manually take out the U-shaped sodium-resistant glass tube and send it to the annealing furnace for annealing, and then connect the exhaust rod 2 to the U-shaped sodium-resistant glass tube 1 (see figure 2 );

[0051] Step 2, sealing: preparation work, con...

specific Embodiment approach 2

[0057] Specific implementation mode two: see Figure 5 with Image 6 In this embodiment, this embodiment is realized based on the inner tube of the multi-U sodium lamp prepared by the method described in Embodiment 1, specifically:

[0058] The compact plasma sodium lamp of this embodiment includes a glass outer tube body 7, a lamp cap 8 and a sodium lamp inner tube 9, the number of the sodium lamp inner tubes 9 is multiple, the glass outer tube body 7 is set on the sodium lamp inner tube 9, and the lamp cap 8 It is arranged at the outer end of the tail of the glass outer tube body 7, and the lamp cap 8 is electrically connected with the sodium lamp inner tube 9; the inner wall of the glass outer tube body 7 is sprayed with tin oxide far-infrared reflective film by plasma spraying method.

[0059] The tin oxide far-infrared reflective film sprayed on the inner wall of the glass outer tube body 7 has the advantages of no pollution and high density, and the tin oxide far-infrar...

Abstract

The invention relates to a manufacturing method of a multi-U sodium lamp inner tube and a compact-type plasma sodium lamp adopting the same, belonging to the technical field of illumination and aiming at solving the problems that an existing low-voltage sodium lamp is low in surface brightness, low in luminous efficiency and longer in overall length. The manufacturing method comprises the following steps of bending a pipe and connecting the bent pipe to an exhaust rod; sealing an opening; exhausting internal gas; filling metallic sodium in the exhaust rod of a U-shaped sodium resistant glass tube with the sealed opening; connecting to a vacuum system; introducing an electric current to a connected conductor so as to generate joule heat, so that alkaline earth metal oxide on an electrode is decomposed; after the decomposition is finished, filling argon gas so that voltage breaks through the gas to generate glow discharge to finish activation; heating the exhaust rod for storing the metallic sodium, wherein the sodium flows into the U-shaped sodium resistant glass tube; filling gas to the U-shaped sodium resistant glass tube and removing the exhaust rod so as to manufacture the multi-U sodium lamp inner tube. A lamp holder of a sodium light source lamp is electrically connected with the sodium lamp inner tube; a tin oxide infrared external reflecting film is sprayed onto the inner wall of an external glass tube body in a plasma spraying manner. The manufacturing method disclosed by the invention is used for manufacturing the multi-U sodium lamp inner tube, wherein the sodium light source is used for illuminating.

Description

technical field [0001] The invention relates to a method for manufacturing a discharge tube of a sodium lamp and a sodium light source lamp thereof, in particular to a method for manufacturing an inner tube of a multi-U sodium lamp and a compact plasma sodium lamp using the tube, belonging to the technical field of lighting equipment. Background technique [0002] Street lamps are devices used to provide illumination for pedestrians and vehicles at night, and the degree of illumination of street lamps directly affects people's visibility of the road. Existing street lamps generally use high-pressure sodium lamps, and low-pressure sodium lamps are replacement products of high-pressure sodium lamps; however, the existing low-pressure sodium lamps have particularly high requirements for lamps and levelness, and the angle is ≥ 15°, so the sodium metal in the lamp will be more attached after vaporization. On the filament, it directly affects the life of the low-pressure sodium la...
