Abstract

The utility model discloses a xenon lamp, which comprises a xenon lamp tube, a lamp holder and a lamp housing. The xenon lamp tube is arranged on the lamp holder. The xenon lamp is characterized in that a coil assembly, an annular magnet, a spring and a spring seat are arranged inside the lamp housing of the xenon lamp. The coil assembly is connected with the bottom of the lamp holder and the annular magnet is fixedly arranged below the coil assembly. The spring is arranged at the annular center of the annular magnet and the upper end of the spring abuts against the bottom of the coil assembly. The lower end of the spring is supported by the spring seat. The xenon lamp can is capable of automatically expanding, which is long in service life. The xenon lamp is widely applied to lighting situations, wherein the focal length is variable, such as automobiles and motorcycle headlights.

Description

A kind of xenon lamp

[technical field]

The utility model belongs to a kind of lighting, particularly a kind of xenon lamp.

[background technology]

Xenon lamp is gained the name because of being full of xenon in the fluorescent tube, xenon lamp has advantages such as the high and low power consumption of brightness, be widely used on the headstock headlight of automobile, motorcycle, the headstock headlight of automobile, motorcycle adopts two different xenon lamps to realize far and near lamp function mostly at present, xenon lamp itself can not be realized autozoom, could realize far and near lamp function so need between two xenon lamps often to switch, the frequent xenon lamp that switches is short service life.

[summary of the invention]

At the deficiency that prior art exists, the purpose of this utility model aims to provide a kind of xenon lamp that can realize autozoom and long service life.

The utility model is implemented by the following technical programs:

A kind of xenon lamp, comprise xenon fluorescent tube, lamp socket and lamp housing, the xenon fluorescent tube is installed on the lamp socket, be provided with coil block, annular magnet, spring and spring base in the lamp housing of xenon lamp, coil block is connected the bottom of lamp socket, and annular magnet is fixed on the below of coil block, and spring is located at the annular center of annular magnet, its upper end leans the bottom at coil block, and the lower end is supported by spring base.

Can produce suction-operated between coil block energising back of the present utility model and the annular magnet, and coil block outage back energy return under spring action, the xenon fluorescent tube that can stretch has automatically just been realized the autozoom of xenon lamp like this, an xenon lamp just need not switch can realize far and near lamp function, xenon lamp long service life.

[description of drawings]

Fig. 1 is a structural representation of the present utility model

[specific embodiment]

As shown in Figure 1, a kind of xenon lamp, comprise the fluorescent tube 3 that is full of xenon, lamp socket 5 and lamp housing 10, xenon fluorescent tube 3 is installed on the lamp socket 5, lamp socket 5 activities are located in the lamp housing 10, be connected with on the lamp housing 10 the hard-wired connector 4 of xenon lamp, be provided with coil block (forming) in the lamp housing 10 by bobbin 7 and coil 8, annular magnet 12, spring 9 and spring base 11, bobbin 7 is connected the bottom of lamp socket 5 by bearing pin 6, annular magnet 12 is fixed on the below of bobbin 7, spring 9 is located at the annular center of annular magnet 12, and its upper end leans in the bottom of bobbin 7, and the lower end is supported by spring base 11, annular magnet 12 and spring base 11 are fixed in the bottom 13 of lamp housing jointly, in addition, the outside of xenon fluorescent tube 3 is provided with lampshade 2, and the top of xenon fluorescent tube 3 is provided with lampshade cap 1.

The xenon lamp of said structure, work as coil electricity, can produce suction-operated between coil and the annular magnet, so bobbin drives lamp socket and fluorescent tube moves down, xenon lamp is realized the function of distance light, and coil blackout, bobbin is return under the effect of spring, drives on lamp socket and the fluorescent tube and retracts the position, so xenon lamp recovers the function of dipped beam, because just need not switching, xenon lamp can not realize far and near lamp function, xenon lamp long service life.

Claims

1. xenon lamp, comprise xenon fluorescent tube, lamp socket and lamp housing, the xenon fluorescent tube is installed on the lamp socket, it is characterized in that: be provided with coil block, annular magnet, spring and spring base in the lamp housing of xenon lamp, coil block is connected the bottom of lamp socket, and annular magnet is fixed on the below of coil block, and spring is located at the annular center of annular magnet, its upper end leans the bottom at coil block, and the lower end is supported by spring base.
