Description of the new type: [Technical field to which the new type belongs] This creation relates to a high-intensity discharge lamp for a vehicle with a lamp cap. [Previous technology] Existing high-intensity discharge lamps with caps are usually structured as ... containing a gas-tight, ellipsoidal gas discharge arc tube made of 咼 pure quartz glass and filled with ionizable substances The two ends of the arc tube are provided with a necked-down and sealed neck body portion at an angle of 180 degrees to each other. In order to ensure the stability of the arc tube, the arc tube and the neck body are also provided with a cover. The cover is made of quartz material that absorbs ultraviolet light. The cover can be air-tight or non-air-tight. The conductors connected to the pair of electrodes of the arc tube respectively extend through the corresponding end neck body to extend out of the arc tube and the casing. The lead near the lamp cap is electrically connected to the power connection terminal provided on the lamp cap, and the other end leads from the shell. The outside is folded towards the lamp cap and electrically connected with another power connection terminal on the lamp cap. '' The housings of existing high-intensity discharge lamps for vehicles are straight, and the arc tube is similar to a sphere or ellipsoid, and the distance from the tubular casing is small, so that the distance between the arc tube and the casing It is very uneven. On the one hand, it will cause uneven temperature of the arc tube and affect the thermal stability. On the other hand, it will cause the light radiated by the electric solitary tube to reach the inner wall of the tubular casing. Out of the enclosure, and another part of the light will be reflected to the ends of the surroundings after repeated reflections between the inner wall of the straight tube enclosure and the outer wall of the arc tube (see M275354 see Figure 3), which not only reduces the light utilization rate5 but also The light distribution curve and the light-gathering effect of the lamp are deteriorated, and a large glare is generated. Most of the products of the existing structure insert the arc tube cover deeply into the lamp holder and fix it with glue. The disadvantage is that it is not strong enough and it is easy to break into the lower part of the bulb, and some are provided with a metal fixing part on the lamp holder. The metal fixing part is welded and connected to the metal ring of the tight-closing shell. The structure of this connection method is relatively complicated, the installation is complicated, and the price is high. [Technical content] The purpose of this creation is to provide a high-intensity discharge lamp for vehicles with a lamp head, which has a simple and firm structure, convenient installation, light utilization efficiency, good thermal stability, and low glare, and can further improve its shock resistance. For the above purpose, the following technical solutions are adopted in this creation: A high-efficiency, low-glare vehicle high-intensity discharge lamp, comprising: an arc / electric tube provided with a spherical or ellipsoidal airtight type and filled with an ionizable object f The end is provided with two sections of the first neck body and the second neck body which are contracted and sealed at an angle of 80 degrees. The first electrode and the second electrode in the arc tube pass through the conductor inside the corresponding end neck and the first electrode lead outside the tube: the electrode lead is electrically connected, and the first electrical wire is connected to the lamp cap provided at the same end. Electrical connection, the second electrode lead is folded back to the direction of the lamp head, and the second power connection terminal is electrically connected in the head direction. The arc tube and the neck body have a cover surrounding the same. The position of the cover and the arc tube is the same. Spherical bulbs or ellipsoids that bulge outward and are similar to arc tubes, both of them M275354 are approximately parallel spherical bulbs. ---- The minus g cb on the second neck body, and the rim of the clamshell octagonal conical surface that is concave in the center, is connected to the shell by sealing. —The lamp holder is an integral structure formed by injection molding of insulating material. The arc tube cap-long and the outer cover of the cover are buried in the front end surface of the lamp holder and fixed to the lamp head by an adhesive. There are no less than three embedded anchor pins on the surface. The embedded ends of each support pin are also distributed at equal distances from the circumference of the concentric circle with the lamp housing. The corresponding welding wings on the metal clamping ring on the cover are fixedly connected. The distance between the cover of this creation and the wall of the spherical arc tube is relatively uniform, so the temperature distribution of the arc tube can be evened, and the thermal stability of the lamp is improved, so that the photoelectric parameters of the lamp are more stable, and Extend lamp life. At the same time, since the wall of the corresponding part of the casing and the arc tube is nearly parallel to the arc tube-like spherical tube wall, the light emitted when the arc tube is ignited is nearly perpendicularly incident on the inner wall surface of the casing, so that more light can be directly directed. Radiation is emitted through the enclosure (see Figure 2), reducing stray light that is reflected multiple times between the inner wall of the enclosure and the outer wall of the arc tube and scattered around and at both ends, improving light utilization and reducing glare. In addition, the diameter of the straight portions at the two ends of the bulb of the shell is reduced, and the weight is reduced to improve the overall seismic performance. The lamp cap created by this invention can be cast and molded with high temperature and high pressure resistant insulating materials. The root of the supporting pin has been embedded and fixed in the lamp mold during molding. The socket of the arc tube neck and the cover should be reserved at the front end of the lamp cap. When assembling, insert the extension of the first neck of the 7 M275354 f arc tube and the cover into the socket of the front surface of the lamp cap, and fix it with high temperature resistant inorganic glue. Then, the support pin rod embedded in the lamp base and the metal clamping ring welding wing sheathed outside the cover are welded and fixed. The arc tube, the cover and the lamp cap are double-fixed with glue and a support frame consisting of a clamping ring and a support pin, which can significantly improve the vibration and shock resistance of the lamp and have a simple structure. , Easy assembly, low cost and so on. In this creation, the upper end of the arc tube is made into a t-shaped shape and then connected with a single bite seal, which can reduce the glare from the upper end, and also shorten the overall body of the lamp = mouth reduction: the weight of the lamp tube 'improves shock resistance' and is easy to pass the traditional F口 口 a production and processing. This creation is particularly suitable as a front light for vehicles. It can be used for locomotives, flying vehicles, or as a special source and used underwater, mines, and other places.

A lamp holder 15 is provided with a stepped plug post with a reduced diameter at the rear. The first electrode lead 6 is located at the center of the cylindrical groove in the front of the lamp holder. The body 51 passes through the lamp holder 15 and the rear of the coffee 15 is provided. In the insertion, the central insertion hole 17 of the insertion rod on the central axis of the wide inner cavity is extended, and is electrically connected to the first power connection terminal 13 outside the vertical rod of 2b.
