Multi-wing shaped deuterium lamp UV light source

Abstract

The invention discloses a multi-wing shaped deuterium lamp UV light source which comprises a deuterium lamp (1), a multi-wing shaped housing (2), a temperature control fan (3), a diaphragm (4), a photoelectric probe (5) and a coupling lens (6). Deuterium lamps are widely used in a plurality of high-precision analyzing apparatuses and equipment, the consumables are short in service lifetime, and have strict requirements on temperature during working. The multi-wing shaped deuterium lamp UV light source utilizes the heat transfer mode of diffusion in cooperation with conduction to realize the heat dissipation of the deuterium lamp by forced air cooling. The multi-wing shaped housing and the temperature control fan are used to control the working temperature of the deuterium lamp to the optimum temperature range, thereby prolonging the service lifetime of the deuterium lamp and improving the light source stability. The multi-wing shaped deuterium lamp UV light source is especially suitable for environmental temperature changes. Stable and reliable mechanical interface and electronic interface facilitate use of a deuterium lamp, the deuterium lamp is simple and fast for replacement, and adjustment is not needed. The coupling lens, the diaphragm and the photoelectric probe can improve the integration level and expansibility of the deuterium lamp light source.

Description

technical field [0001] The invention relates to the technical field of deuterium lamp ultraviolet light source design, in particular to a multi-fin deuterium lamp ultraviolet light source. Background technique [0002] In recent years, with the development of science and technology and industry, ultraviolet radiation has been widely used in material science, energy science, space science, environmental science, medical and health and many other scientific production fields. As an ideal ultraviolet light source, deuterium lamp is widely used in a variety of high-precision analytical instruments and equipment, such as trace gas analyzers, ultraviolet spectrophotometers, high performance liquid chromatography, capillary electrophoresis, flue gas analyzers, medical instruments, Densitometer and colorimeter, etc. When the deuterium lamp is working, that is, after the filament is energized and heated, free electrons are emitted, and at the same time the anode is applied with volt...

AI Technical Summary

Problems solved by technology

Therefore, the temperature of the glass shell needs to be maintained at 245°C to 280°C, and the maximum temperature should not exceed 290°C. If the temperature is too high or too low, the gas in the lamp will be consumed faster, the energy will be reduced, and the life will be shortened.

The traditional method uses natural diffusion or convection to dissipate heat, which is greatly affected by the ambient temperature and cannot guarantee the optimal working temperature of the deuterium lamp, and external temperature changes will cause output drift and reduce the stability of the deuterium lamp source
