Abstract

The utility model relates to a xenon long-arc lamp, comprising a lamp tube, a lamp cap and an electrode which are arranged at two ends of the lamp tube; glass partitions with holes are respectively arranged at the two ends of the tube lamp; the glass partition divides an inner chamber of the lamp tube into a middle sectional luminous zone and two protecting zones at the two ends, the protecting zone comprises the lamp cap; in the xenon long-arc lamp, most scattered metal steam is blocked in the protecting zones at the two sides of a lamp shell by the glass partitions, so as not to be easily diffused in the luminous zone; decaying rate of luminous flux is slowed down, thus prolonging the service life.

Description

A kind of xenon long-arc lamp

Technical field

The utility model relates to xenon long-arc lamp.

Background technology

Xenon long-arc lamp belongs to arc discharge type gaseous discharge lamp, is sealed with the quartz glass lamp vessel of electrode by two ends and forms with two lamp holders that link to each other with two electrodes respectively, is filled with the xenon of nearly 100Kpa pressure in the fluorescent tube, structure such as Fig. 1.This lamp can give off the spectrum very similar to sunlight, be commonly called as and be " Sunny ", therefore can be used as the lighting source of square, station, harbour, the first-class large tracts of land occasion of train, in addition, it also can be used for printing the special source of occasions such as photomechanical process, the check of cloth color, ageing of rubber test, artificial climate plant culture photochemical reaction, camera technique and infrared heating, and is of many uses.Yet, the tradition xenon long-arc lamp is the through type fluorescent tube, growth along with the operating time, two end electrodes loss, scattering increase, the metallic vapour of black is diffused into the luminous zone between two electrodes, and the light transmittance of lamp housing is reduced, and luminous flux is sharply decayed, quickened the termination in life-span, so useful life is shorter.

Summary of the invention

The purpose of this utility model is that traditional xenon long-arc lamp is improved, and a kind of xenon long-arc lamp of long service life is provided.

The utility model xenon long-arc lamp; the lamp holder and the electrode that comprise fluorescent tube, lamp tube ends; lamp tube ends is equipped with a glass partition with holes respectively, and this glass partition is separated into two protection zones in luminous zone, stage casing and two ends with the fluorescent tube inner chamber, and said lamp holder is included in the protection zone.

The utility model further improves the spherical structure of protection zone for enlarging that is lamp tube ends.

When xenon long-arc lamp of the present utility model is worked, the metallic vapour of most of scattering is stoped in the protection zone of lamp housing both sides by glass partition and is not easy to be diffused into the luminous zone, therefore thereby the rate of decay of the luminous flux that slowed down greatly can prolong useful life of xenon lamp; In addition, lamp tube ends is made the spherical structure of expansion, can improve the volume of protection zone, further improve the useful life of lamp.

Description of drawings

Fig. 1 is traditional xenon long-arc lamp structural representation.

Fig. 2 is the utility model xenon long-arc lamp structural representation.

Among the figure: 1,1-1 is a lamp holder, 2,2-1 is electrode tip, and 3 is fluorescent tube, 4,4-1 is glass partition with holes, 5,5-1 is the protection zone, 6 is the luminous zone.

As shown in Figure 1: it is made up of quartz burner 3, receiving electrode 2,2-1 and lamp holder 1, a 1-1 for existing xenon long-arc lamp structural representation, is filled with the xenon of nearly 100Kpa pressure in the fluorescent tube 3.

As shown in Figure 2, the utility model xenon long-arc lamp is provided with fluorescent tube 3, electrode tip 2,2-1 and lamp holder 1,1-1, and electrode tip 2,2-1 link to each other respectively with lamp holder 1,1-1, and the inner chamber of fluorescent tube is filled with the xenon of nearly 100Kpa pressure.Spherical protection zone 5, the 5-1 of the two ends of fluorescent tube 3 for enlarging, the stage casing is luminous zone 6, is separated by with the glass partition 4, the 4-1 that have centre bore respectively between protection zone 5,5-1 and the luminous zone 6, two glass partitions are equal.Lamp holder 1,1-1 lay respectively in two protection zones.

Claims
