Embodiment Construction

[0019] Now in conjunction with the accompanying drawings, the structure and process of the present invention will be further described.

[0020] The high-efficiency and long-life sodium lamp is composed of a glass lamp housing 14, an arc tube 1, a lamp cap 12 and corresponding conductive brackets. The two ends of the arc tube are connected to the storage electrode 3 through the niobium-zirconium tube 4, and the starting wire 2 is also connected to the outer wall of the arc tube. . The niobium zirconium tube and the reserve electrode are welded by laser. When the niobium-zirconium tube is sealed with the arc tube, a glassy sealing ring 5 is used, and the glassy sealing ring is alkaline solder. Before the two ends of the arc tube are sealed, sodium amalgam 7 and xenon gas 6 are firstly filled into the arc tube so that the buffer gas xenon inside the arc tube reaches 40Kpa. One end of the arc tube is welded to the stainless steel E-shaped connecting piece 9 through the niobium-...

Abstract

The invention relates to a sodium lamp with high lighting effect and long service life and a process method, belonging to the technical field of energy-saving electric light sources. The sodium lamp comprises a glass lamp shell, a lamp head, an electric arc tube and a corresponding conductive support, wherein the electric arc tube consists of storage-type electrodes and a niobium-zirconium tube; sodium amalgam and xenon are filled in the electric arc tube; and the conductive support is divided into a big support and a small support, the big support and the small support are respectively connected with two ends of the electric arc tube and a glass lamp wick. The design essential is that the outer surface of the electric arc tube is wound with two coils along the axial direction; the two coils are respectively adjacent to the storage-type electrodes at the two ends of the electric arc tube; and the coils are conductively connected with each other through starting wires. The invention has reasonable structure, feasible method, luminous flux and prolonged service life, realizes a simpler and more effective way on assisting to start so that the operation of the sodium lamp is more reliable and stable, and the structure is suitable to be used as illumination equipment in occasions, such as roadways, airport terminals, ports, bus stations, plazas and the like and the sodium lamps in the same kinds.

Description

technical field [0001] The invention relates to the technical field of energy-saving electric light sources, in particular to high-efficiency and long-life sodium lamps for lighting and a process method. Background technique [0002] Sodium lamps use sodium vapor discharge to produce visible electric light sources. Sodium lamps are further divided into low-pressure sodium lamps and high-pressure sodium lamps. The working vapor pressure of low-pressure sodium lamps does not exceed a few Pa. The discharge radiation of low-pressure sodium lamps is concentrated on two double-D spectral lines at 589.0 nanometers and 589.6 nanometers. They are very close to the highest value of the human eye's visual curve (555 nanometers), so their luminous efficiency is extremely high, and it has reached 200 currents per watt. (lm / W), becoming the energy-saving light source with the highest luminous efficiency among various electric light sources. The working vapor pressure of high-pressure s...
