Fluorescent tube sets and high-power fluorescent lamps with high light output in high-temperature environments

Abstract

The invention belongs to the field of lighting, and specifically relates to a fluorescent lamp group with high light output in a high-temperature environment, which includes a discharge tube, and the discharge tube is formed by connecting at least three fluorescent lamp tubes. One end of the body is provided with an electrode, and at least one fluorescent tube is provided with a mercury insert for placing amalgam, and the discharge tube is filled with a mixed inert gas, wherein the amalgam is placed in at least one of the mercury tubes. In the intubation tube, the amalgam is placed outside the fluorescent tube monomer, and the distance between the bottom end of the amalgam and the sealing end surface of the fluorescent tube monomer is -5 mm to 20 mm; the mixed inert gas composition includes neon or helium and argon , Krypton gas at least one, the inflation pressure is 2-5 Torr. The fluorescent tube set provided by the invention and the fluorescent lamp produced by the tube set have the characteristic of high light output even in high temperature environment.

Description

technical field [0001] The invention belongs to the field of lighting, and in particular relates to a fluorescent tube group with high light output in high temperature environment and a high-power fluorescent lamp with high light output in high temperature environment composed of it. Background technique [0002] At present, the conventional technology of tri-color high-power fluorescent lamps is filled with inert gas by krypton gas, argon gas or argon-krypton mixed gas. This technology tri-color energy-saving lamps, especially high-power or super-high-power energy-saving lamps, from the perspective of lampshade matching, has a long Defects that are too long or have a large lamp volume. Due to outdoor lighting shades such as street lamp shades, tunnel lamp shades, floodlight shades, etc., the internal volume of the sealed reflector is limited by the length or volume, and various types of lighting have different standard requirements. The energy-saving lamps cannot be instal...

Problems solved by technology

Due to outdoor lighting shades such as street lamp shades, tunnel lamp shades, floodlight shades, etc., the internal volume of the sealed reflector is limited by the length or volume, and various types of lighting have different standard requirements. The energy-saving lamps cannot be installed in the lampshade or can be installed, but the utilization factor of the lamps is very low, and the brightness effect is poor. Therefore, it is necessary to reduce the number or length of the discharge tube while maintaining the power, and reduce the volume of the lamp in order to match the existing lamps.

However, if the high-power fluorescent lamps of conventional technology reduce the number or length of discharge tubes while maintaining the power, the temperature of the discharge tubes will rise and the light efficiency will decrease, and it will not even reach the size and volume that can be applied to outdoor lighting.

An invention patent applied by the inventor, the invention name is: high-power miniaturized fluorescent lamp, and the application number is: CN200810060685.3. The high-power fluorescent lamp of this invention can achieve high light output at room temperature, but the fluorescent lamp works equally Does not maintain lamp power or lamp brightness well
