Abstract
A low dazzle vehicle high gas pressure discharge lamp with holder of the utility model is provided with a gas-tight electric arc pipe (3) similar to a sphericity or an ellipsoid. Two ends of the electric arc pipe are respectively provided with neck bodies which are contract in diameters. A first electrode and a second electrode in the electric arc pipe are respectively and electrically connected with a first contact conductor (7) and a second contact conductor (14) which extend out of a bulb. The first contact conductor is electrically connected with a first power supply tab (11) on a lamp holder (10) provided at the same end. Then the second contact conductor folds toward the lamp holder and is electrically connected with a second power supply tab (12) on the lamp holder. The outside of the electric arc pipe is provided with a housing (5) encompassing them. The discharge lamp is characterized in that : on the corresponding position of the electric arc pipe the housing is provided with a spheroidal bulb (5a) which bloats outward, has a spherical or axiolitic wall similar to the electric arc pipe and is close to be parallel. The utility model can make the temperature of the electric arc pipe more homogeneous and the heat endurance and the photoelectric properties be improved. Simultaneously the utility model can make more energy of light directly cross through the housing and radiate out, and the model also reduces glare of the stray light caused by reflecting toward both sides along the housing.
Description
Technical field
The utility model belongs to a kind of automobile-used high-pressure discharge lamp of low dazzle of single-ended band lamp holder.
Background technology
The common structure of the high-pressure discharge lamp of single-ended band lamp holder 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 (referring to Fig. 2), 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 technical problems to be solved in the utility model provides a kind of automobile-used high-pressure discharge lamp with single-ended band lamp holder of high thermal stability energy, low dazzle.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with spheroidal or ellipsoid shape and is filled with the electric arc tube (3) of ionisable substance, electric arc tube two ends are respectively equipped with diameter contraction that is mutually 180 degree angles and the neck body (3a) that seals, (3b), first electrode (4) in the electric arc tube, second electrode (2) is respectively by electric conductor in the corresponding end neck body and outer first contact conductor (7) of protruded tube, second contact conductor (14) is electrically connected, first contact conductor (7) is electrically connected with first power connector end (11) on the lamp holder that is located at same end (10), second contact conductor (14) then is folded to lamp holder and is electrically connected with second source link (12) on the lamp holder, electric arc tube and neck body are provided with the case (5) that surrounds it outward, it is characterized in that: described case (5) is bordering on the spherical cell-shell (5a) of parallel class being provided with outwards to bloat and be with electric arc tube spheroidal or ellipsoid shape wall with the corresponding position of electric arc tube.
Distance between the spherical electric arc tube outside wall surface of case of the present utility model and class 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 with electric arc tubing bulb tube wall, 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 can inwardly withdrawing at the position of electric arc tube neck body, so can alleviate the weight and volume of case, improve 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.
