Multi-U compact integrated low-pressure sodium lamp

Abstract

The invention discloses a multi-U compact integrated low-pressure sodium lamp, and belongs to the technical field of lighting devices. The low-pressure sodium lamp mainly comprises a lamp holder, a tube and a lamp socket, wherein the tube comprises an outer tube housing and an inner tube, the inner tube is of an U shape, a flat opening is arranged on the sealing end of the outer tube housing, and the lamp socket comprises an outer lamp socket housing and a cylindrical electronic ballast. The electronic ballast is arranged in the outer lamp socket housing, one end of the electronic ballast is directly connected with the inner tube through the flat opening on the sealing end of the outer housing, and the other end of the electronic ballast is connected with the lamp holder. The multi-U compact integrated low-pressure sodium lamp employs a plurality of U-shaped inner tubes to form plasma discharge channels. The size of the tube is greatly reduced while energy-saving performance and high brightness are ensured. The production cost and installation cost are substantially reduced, the service lifetime is prolonged, and the lamp is insensitive to ambient temperature change.

Description

technical field [0001] The invention relates to a multi-U compact integrated low-pressure sodium lamp, which belongs to the technical field of lighting equipment. Background technique [0002] Low-pressure sodium lamps have been mainly used as low-power monochromatic light sources in optical instruments such as polarimeters, refractometers, and polarizers. High-power lighting lamps have not been widely used due to technical constraints such as lamp body structure, electrode loss, and high manufacturing costs of lamp tubes. [0003] Low-pressure sodium lamps are characterized by high luminous efficiency, low power consumption, energy saving and environmental protection, long service life, golden yellow light color, and strong fog penetration ability. They are suitable for monochromatic lighting in roads, airports, docks, stations, and industrial and mining enterprises. However, because low-pressure sodium lamps in the prior art have particularly high requirements on lamps an...
