Ultra-high pressure mercury lamp light source system
When ignited, the vapor pressure of mercury reaches more than 10 atmospheres. It has the characteristics of small volume, high brightness, strong radiation of visible light and ultraviolet energy, and can be used as a strong light source for fluorescence microscopes, optical instruments and lithography. The ultra-high pressure mercury lamp parallel light source system utilizes an electric light source that generates mercury vapor when mercury is discharged to obtain visible light. Mercury lamps are divided into high pressure mercury lamps and ultra high pressure mercury lamps. The working mercury vapor pressure of the high pressure mercury lamp is 0.2 to 1 MPa. Its luminous efficiency can reach 35 ~ 50 streams / watt (lm / W), widely used in streets, squares, tall buildings, transportation sites with ambient temperature of -20 ~ 40 °C as indoor and outdoor lighting sources. The ultra-high pressure mercury lamp has a working mercury vapor pressure of 1 MPa or more. The lamp has strong radiation from long-wave ultraviolet to visible light, and the arc brightness is extremely high. The higher the vapor pressure of mercury, the richer the visible light portion and the higher the arc brightness. Ultra-high pressure mercury lamps are available in short-arc ultra-high pressure mercury lamps and capillary ultra-high pressure mercury lamps. The short-arc ultra-high pressure mercury lamp is a point source that emits extremely long-wave ultraviolet light and visible light. It is widely used in optical instruments such as fluorescence microscopy, ultraviolet spectrometer, and holography, and is also used in integrated circuit lithography. Capillary ultra-high pressure mercury lamps are mainly used in photoengraving and color picture tube coating fluorescent screen making processes. If the starting gas of the ultra-high pressure mercury lamp is changed to helium, the starting performance can be improved to make it suitable for locomotive headlights.
