Abstract
The present invention discloses a vehicle high intensity discharge lamp with a lamp holder, which comprises an electrical arc tube filled with ionizable substances and a lamp holder, both ends of the electric arc tube are respectively provided with a first neck body and a second neck body which present a 180 DEG angle and are sealed, wherein the diameters of the first neck body and the second neck body are shrunk. A cover casing surrounding the electrical arc tube and the neck bodies are respectively arranged outside the electrical arc tube and the neck bodies. Two pairs of electrodes are arranged in the electrical arc tube and are externally connected with a conducting wire, wherein one electrode couple is positioned on an extension line of the axial line of the lamp holder, and the other electrode couple deviates from the axial line of the lamp holder. Two groups of discharging electrodes are arranged in the same electrical arc tube by the present invention. Replacing the discharge electrode couple can replace the electrical arc (light source) position, and thereby, the shape and the illumination distribution of outgoing beams can be adjusted, and the main beam and the dipped beam switching function of an automobile can be nicely realized. The function of the present invention is the same with that of a common double-lamp filament tungsten halogen lamp (9007) and can be directly replaced to be used to increase the illumination efficiency.
Description
Technical field
The invention belongs to a kind of automobile-used high-intensity discharge lamp with lamp holder.
Background technology
The common structure of the high-intensity discharge lamp of single-ended band lamp holder is: comprise the airproof that a usefulness pure quartz glass makes and be filled with spherical or axiolitic gas discharge electric arc tube of being of ionisable substance, electric arc tube comprises pair of electrodes, the electric arc tube two ends are provided with diameter contraction that is mutually 180 degree angles and the neck body part that seals, two neck bodies support an electrode respectively, and contact conductor passes through from neck body central authorities.This electric arc tube can directly be used as light source.In order to guarantee the stability of electric arc tube work, electric arc tube and neck body be outer can be provided with by can absorbing the case that ultraviolet quartz material is made, and case is airproof normally, and its two ends are connected with electric arc tube neck body part banding by closing up.Pass on this end lamp holder aperture near the lead-in wire of first electrode of lamp holder and draw, then be folded to the aperture that lamp holder passes on the lamp holder away from second contact conductor of lamp holder and draw from the outside of case.This use for discharge lamp can provide a kind of fixing illuminating bundle---distance light or passing beam when automobile headlamp throws light on.Switch and must adopt two to overlap the independently illuminator cooperation that comprises discharge lamp, ballast and other accessory, annex and carry out for carrying out distance light, dipped beam.System complex, cost height have certain dark time zone to exist, and will produce the high pressure trigger impulse during switching.
Summary of the invention
The purpose of this invention is to provide a kind of electric arc that can produce two diverse locations in same discharge lamp, and can switch mutually easily being applicable to the high-intensity discharge light source of the car headlamp that has dipped beam, distance light concurrently and can conveniently switch, this charging source can be with the automobile-used high-intensity discharge lamp that is the band lamp holder.
Addressing the above problem at first is theoretic breakthrough, it has been generally acknowledged that in same container to produce two independently electric arcs, and therefore, never the someone imagines two discharge lamps of manufacturing in same cell-shell.We have negated this viewpoint, have invented the discharge lamp of the two pairs of electrodes of appropriate position placement in same cell-shell, can produce electric arcs two appropriate positions and also can switch mutually.Its technical scheme is: the present invention is provided with an axial symmetry or slightly is pancake spheroidal or ellipsoid shape and be filled with the electric arc tube of ionisable substance, electric arc tube two ends are respectively equipped with diameter contraction that is mutually 180 degree angles and first neck body, second neck body that seals, be provided with two electrodes of first end and two electrodes of second end in the electric arc tube, two electrodes of first end and two electrodes of second end are electrically connected with the corresponding outer lead that passes lamp holder by the electric conductor in the corresponding end neck body respectively.Wherein pair of electrodes is on the line stretcher that is in the lamp holder axis, and another departs from the lamp holder axis to electrode pair.This electric arc tube can directly be used as light source, also can be provided with outer casing 7 outside electric arc tube and neck body.This electric arc tube can directly be fixed on the lamp holder, also can utilize holding ring to fix, and holding ring 8 is enclosed within the case bottom on the outer wall of the suitable height of lamp holder.Be no less than in three the end recessed luminaire end surface of support pin rod 9 and fix with lamp holder, the other end respectively with the fixing welding of holding ring respective airfoil.Second neck body 2b upper end is the tubaeform taper seat 2c under the central fovea, and tubaeform taper seat outer rim is sealed with case 7 and is connected, and perhaps the case upper port is shunk the 7b and the second neck body sealing-in.
Be provided with two couples of electrode 3a in the electric arc tube of the present invention, 4a and 3b, 4b.When energized forms electric arc between pair of electrodes therein, then between this is to electrode, form an arcuation bright light source.When with power supply transfer to another to electrode between the time then electric arc transfer to immediately this to electrode between, rapidly realization almost is that the bright spot of zero transit time is switched.The present invention can realize distance light, the dipped beam handoff functionality of automobile well.Its function is identical with two filament tungsten halogen lamps (9007) commonly used, and can directly replace use.Owing to collect dipped beam, distance light light source in a lamp, and can in same light fixture, power, control and switch same lamp with same electric ballast, thereby improved dipped beam, distance light switch speed and beam quality, and the generation of high pressure when having avoided switching, cost also reduced simultaneously.
