Description

technical field

[0001] The invention relates to a deuterium lamp used as a light source for analytical test instruments, in particular to a deuterium lamp with glow resistance. Background technique

[0002] Deuterium lamp is a light source of arc discharge type in gas discharge lamp. When it works, it can radiate 160nm~400nm continuous distribution of ultraviolet spectrum from the light window, so it is an ideal ultraviolet light source for ultraviolet spectrophotometer. The lamp is filled with Deuterium gas (~10mmHg), filament voltage Vf<2~10V, AC or DC. Starting voltage Vs ~ 300V DC stabilized current power supply, working voltage Va = 70 ~ 100V after starting. Working current ~ 300mA. The luminescent mechanism of the deuterium lamp is: the thermal electrons emitted by the cathode of the filament move towards the anode under the acceleration of the electric field and are excited by the inelastic collision with the deuterium gas molecules, thereby radiating the continu...
