The electric arc tube is in a shape similar to a spherical shape, an axiolitic shape or a tubular shape and is filled with ionized substances. A first end electrode 3a and a second end electrode 3b are separately arranged at both ends in the electric arc tube 1. A first seal neck 2a and a second seal neck 2b which are sealed at an angle of 180 DEG are separately arranged at both ends of the electric arc tube 1, and the diameters of the first seal neck 2a and the second seal neck 2b are contracted. The first end electrode 3a and the second end electrode 3b are separately and electrically connected with outer leads by an electric conductor in a corresponding end neck body; cylindrical casings surround the electric arc tube 1, the first seal neck 2a and the second seal neck 2b. The utility model is characterized in that the diameter of the casing 4a outside the first neck body 2a and the diameter of the casing 4b outside the second neck body 2b are smaller than the diameter of the casing 5 outside the electric arc tube 1; the casings 4a, 4b are separately connected with the casing 5 by a connecting wall surface 6 at an angle alpha, wherein 180 DEG > alpha >90 DEG. The utility model can make the temperature of the electric arc tube more uniform, and improve the thermal stability and the photoelectric properties; meanwhile, the utility model enables more light to directly emit out through the casing, and the glare of the stray light caused by the reflection of the light along the casing toward both ends.
Description
Technical field
The utility model belongs to a kind of automobile-used high strength high-pressure discharge lamp electric arc tube.
Background technology
The common structure of automobile-used high-pressure discharge lamp is: what comprise the airproof that a usefulness pure quartz glass makes and be filled with ionisable substance is spheroidal or axiolitic gaseous arc pipe, and the electric arc tube two ends are provided with that the diameters that are mutually 180 degree shrink and the neck body part of sealing.In order to guarantee the stability of electric arc tube work, electric arc tube and neck body also are provided with case outward, and case is made with the quartz material that can absorb ultraviolet light, can be airproof, also can be non-airproof.The lead that is connected with the electric arc tube pair of electrodes passes the corresponding end neck body respectively and stretches out electric arc tube and case, first end lead-in wire is electrically connected with power connector end on being located at this end lamp holder, and the other end goes between then and to be folded to lamp holder outside the case and to be electrically connected with another power connector end on the lamp holder.The case of the automobile-used high-pressure discharge lamp of existing both-end is straight-cylindrical, and electric arc tube is spheroidal or axiolitic, and and the distance between the tubulose case is very little, make that distance is very inhomogeneous between electric arc tube and the case, can cause the inhomogeneous of electric arc tube temperature so on the one hand, influence thermal stability, because of having radiation meeting greatly repeatedly to reflect between encloser inner wall and electric arc tube outer wall greatly, incidence angle looses in the time of can causing the radiation of electric arc tube to arrive tubular cover shell inwall on the other hand to two ends, this not only can reduce light utilization efficiency, also can make the spotlight effect of light distribution curve and light fixture become bad, increase dazzle.
Summary of the invention
The purpose of this utility model provide a kind of in light weight, anti-seismic performance good, have high thermal stability can automobile-used high strength high-pressure discharge lamp electric arc tube.
The technical scheme that addresses the above problem is (referring to an accompanying drawing 1): the utility model is provided with an electric arc tube 1 that slightly is pancake spheroidal or ellipsoid shape and is filled with ionisable substance, first end in the electric arc tube 1, be respectively equipped with the first termination electrode 3a, the second termination electrode 3b, electric arc tube 1 two ends are respectively equipped with diameter contraction that is mutually 180 degree angles and the first sealing-in neck 2a, the second sealing-in neck 2b that seals, and the first termination electrode 3a, the second termination electrode 3b are electrically connected with outer lead by the electric conductor in the corresponding end neck body respectively.The first neck body 2a, the second neck body 2b are respectively equipped with the cylindrical electric arc tube first sealing-in neck case 4a, the electric arc tube second sealing-in neck case 4b that surrounds it outward, be provided with cylindrical electric arc tube case 5 outside the electric arc tube 1, the diameter of the cylindrical electric arc tube first sealing-in neck case 4a, the electric arc tube second sealing-in neck case 4b is less than cylindrical electric arc tube case 5, if but that the cylindrical electric arc tube first sealing-in neck case 4a is connected with the electric arc tube second sealing-in neck case 4b is in alignment, then the cell-shell edge of electric arc tube 1 can not exceed this straight line.The cylindrical electric arc tube first sealing-in neck case 4a, the electric arc tube second sealing-in neck case 4b are connected 180 °＞α＞90 ° by connecting wall 6 respectively with cylindrical electric arc tube case 5 with the α angle.
Distance between case of the present utility model and the electric arc tube outside wall surface is more even, so can make the electric arc tube temperature more even, the thermal stability of lamp is improved, thereby make the photoelectric parameter of lamp more stable, also can prolong the useful life of lamp, simultaneously because case is bordering on parallel with the tube wall of electric arc tube corresponding position, the light that is sent when electric arc tube is lighted is in the incident of encloser inner wall face near vertical, so can make more light directly see through case radiate, reduced and between encloser inner wall and electric arc tube outer wall, repeatedly reflected and diffusing stray light to two ends, improved light utilization efficiency, reduced dazzle, in addition, on the utility model case, down around inwardly withdrawing at the position of electric arc tube neck body, so alleviated the weight and volume of case, improved whole anti-seismic performance.The utility model is specially adapted to do vehicle head lamp, also can be used for the vehicles such as locomotive, aircraft illumination or as special projection source be used under water, mine, kitchen window and other places of being used for illumination is had relatively high expectations.
