Shading rack for telescopic xenon lamp and telescopic xenon lamp for vehicle

Abstract

The invention discloses a shading rack and a telescopic xenon lamp for a vehicle. The shading rack comprises a bracket and a shading cap positioned on the top of the bracket, wherein the bracket comprises a connecting part connected with the shading cap, a semicircular shading part extending from the bottom end of the connecting part, a first supporting part arranged at the bottom of the shading part, a first fixing part arranged at the bottom end of the first supporting part, a rod-shaped second supporting part extending from part of the bottom end of the connecting part, and a second fixing part which is arranged at the bottom end of the second supporting part and is used for being fixedly connected with a mounting base. The telescopic xenon lamp comprises a mounting base, a telescopic xenon bulb component and the shading rack, wherein the mounting base is provided with an accommodating cavity; one end of the telescopic xenon bulb component is arranged in the accommodating cavity; the shading rack is arranged on the mounting base; and the telescopic xenon bulb component comprises a lamp holder bulb base, a lamp holder bulb in which a luminous bulb source is arranged, an electrode wire positioned outside the lamp holder bulb, a porcelain tube sleeved on the electrode wire and a shading piece fixed on the lamp holder base. The shading rack has a reasonable and compact structure, and the illuminating brightness can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of lighting lamps, and in particular relates to a shading frame for a xenon telescopic lamp and a vehicle xenon telescopic lamp made of the shading frame. Background technique [0002] The front headlights of automobiles are divided into low beam lighting and high beam lighting. According to traffic law regulations, when vehicles are driving at night and encounter vehicles and pedestrians, the lights should be converted into low beam lighting so that the other party will not be dazzled and avoid avoid traffic accidents. [0003] In the past, there was a lighting method in which an ordinary halogen lamp was installed on the HID bulb to change the light of the far and near lights. Because the brightness and life of the halogen lamp could not be compared with the HID lamp, the low beam of the headlight was dim and did not work. The light and light are inaccurate, and there is no astigmatism and light leakage a...

AI Technical Summary

Problems solved by technology

This structure has an unreasonable design in terms of lighting, because the original car headlight assembly includes a shading shield covering the outside of the xenon telescopic lamp. The support of the shading shield is an up and down vertical structure perpendicular to the horizontal plane. And the existing xenon telescopic lamp shade support structure adopts the left and right balance design parallel to the horizontal plane. Part of the light is also blocked by the support of the shading shield in the headlight assembly, which will block more part of the light emitted by the telescopic bulb. In addition, the shading area of ​​this kind of shading plate is too large, making the light More than 20% of the brightness was wasted in vain, and the light concentration of the high beam is not accurate, the light and dark cut-off line of the low beam is not clear, and the phenomenon of light leakage and astigmatism; at the same time, the volume is large, which leads to some models that cannot be installed, which brings many problems to maintenance and installation. inconvenient
