Abstract
The utility model provides a 55W xenon lamp tube which serves as the headlamp of a train. A gas discharge lamp tube for the train comprises an inner tube body and an outer sleeve; a closed discharge cavity is arranged on the inner tube body; the discharge cavity is in an ellipsoidal shape; a first electrode and a second electrode are respectively inserted into the discharge cavity from both ends of the length of the discharge cavity, and a distance D between the first electrode and the second electrode is 4.2mm; the height H of the discharge cavity is 4+/-0.5mm, and the length L of the discharge cavity is 8+/-1mm; and the inner tube body is protected by the outer sleeve. The gas discharge lamp tube for the train is used as the headlamp of the train, has the characteristics of high light-emitting intensity, concentrated focal point and the like, and is more energy-saving, environment-friendly and durable than a halogen lamp.
Description
Technical field
The utility model relates to a kind of gas-discharge lamp of train.
Background technology
Matching used headlamp is generally the halogen tungsten bulb of 110V on the existing train, but there are shortcomings such as life-span weak point, power is big, heating is big in such light source.Gas-discharge lamp is compared with halogen tungsten bulb, has longer service life, more energy-conservation, advantage such as environmental protection more.The advantage of the xenon lamp in the gas-discharge lamp is more outstanding.Yet the current special not supporting xenon lamp that uses aboard and relevant ballast product make xenon lamp application aboard be very restricted.
For overcoming the above problems, need improve the specification of existing xenon lamp.
The utility model content
The utility model provides the supporting xenon lamp fluorescent tube as the train headlamp of a kind of 55W.
By the following technical solutions:
Train gas-discharge lamp fluorescent tube comprises interior tube body, and interior tube body is provided with airtight discharging chamber, and discharging chamber is elliposoidal, and first electrode and second electrode are inserted in the discharging chamber from the two ends of the length of discharging chamber respectively; First electrode and the second distance between electrodes D are 4.2mm; The height H of discharging chamber is 4 ± 0.5mm, and length L is that length is 8 ± 1mm; Also be provided with outer tube, described interior tube body is among the protection of outer tube.
The diameter of the diameter of above-described first electrode and second electrode is preferably in 0.3～0.5mm, is thorium tungsten electrode.
As preferred version, first electrode preferably by first molybdenum sheet and with the first electrode leads to client conducting; Second electrode preferably by second molybdenum sheet and with the second electrode leads to client conducting.
The gas-discharge lamp fluorescent tube of above specification is applicable to the situation of xenon lamp.The fluorescent tube of this structure is the ballast of 55W when using with supporting rated output power, can provide the effect of points of proximity light source, and service life is the longest, compatible best with existing light fixture on the train.But and the ultraviolet radiation that outer tube filtering discharging chamber produces, and protection internal discharge cavity.
Characteristics such as the usefulness that gas-discharge lamp fluorescent tube of the present utility model is used for shining before the train has the luminous intensity height, and focus is concentrated are than more energy-saving and environmental protection of Halogen lamp LED, durable.
