The lamp socket of high-pressure discharge lamp

Technical field

The utility model relates to a kind of holder structure that is used to install the high-pressure discharge lamp bulb, particularly a kind of lamp socket that can change installation direction according to the different size reflector.

Background technology

The illuminating lamp (being commonly called as " head lamp " or " headlight ") of general vehicle front all has the function of switching high beam or dipped headlights, so that meet different driving road-condition requirements.

Adopt far away, the low beam switching construction of high-pressure discharge lamp (or title " xenon head lamp ") to have two kinds substantially at present, wherein a kind of is that a lamp socket that is used for making up bulb is set in a lampshade, lamp socket is connected in an electromagnetically operated valve, start during by electromagnetically operated valve energising or outage is can the interlock lamp socket movable in lampshade, change the distance between this bulb and the lampshade internal reflection surface according to this, utilize the just effect of far away, the low beam switching of may command of a bulb to reach.Yet, because the distance between bulb and the reflector is not simultaneously, the light focal length that is reflected is also inequality, and can cause high beam or dipped headlights because of the shining shortcoming of loosing of reverberation that poor focusing produces, allow the night motorist can't correctly judge the actual distance that subtend is sent a car, therefore have an accident easily.For example, when dipped headlights correct focal length if car light is correction during fabrication, then move to when nearer when bulb apart from reflecting surface, can cause that reverberation is fuzzy, shining to loose because lose burnt; Otherwise, when high beam correct focal length if car light is correction during fabrication, then move to when farther when bulb apart from reflecting surface, also can cause fuzzy, the shining problem of loosing of reverberation because losing burnt.

Another kind is far away, the low beam switching construction then is used for improving aforesaid problem, and its technological means is that bulb is arranged at lamp socket, and lamp socket then is installed on reflector, makes bulb be positioned at the position that focuses of reflector; Lamp socket is also established other setting and is positioned at downside and can movable screening penetrates sheet, and this screening is penetrated sheet and is controlled mechanism controls and can folds or open; When screening is penetrated sheet and opened, can allow the light of bulb project reflector and reflex to place far away more comprehensively to form high beam; And, then penetrate the below that sheet covers bulb by screening when hiding when penetrating sheet and folding, and allow light only project reflector from the top, reflex to nearer place to form dipped headlights by reflector again.

Present high-pressure discharge lamp is a kind of form of fluorescent tube, one end of fluorescent tube is combined in tube face, and the other end then extends plain conductor, plain conductor is extended in the tube face be electrically connected with electronic building brick, the tube face recombinant is combined in lamp socket the center of reflector again in lamp socket; The described plain conductor that exposes must sheathed insulated tube (being generally ceramic material makes).

Fig. 6 shows the lamp socket of known high-pressure discharge, and its structure is to be provided with a through hole A1 who is used to install tube face at lamp socket body A, and the edge of lamp socket body is provided with an alar part A2 who is used for being positioned at the location hole of reflector; When lamp socket A and reflector combination, directly the lamp socket body is inserted in the centre bore of reflector, and makes alar part A2 be inserted in fixing again the getting final product of location hole of reflector.The automobile of different labels, the reflector specification of its illuminating lamp may be inequality, therefore described location hole be located at the position of reflector also may be inequality; Some is located at the top at reflector centre bore edge with location hole, and some then is located at below, centre bore edge.Therefore, when known lamp socket was combined in the reflector of different size, meeting cause insulated tube to be positioned at the top or be positioned at the situation of below because of the difference of the position of positioning hole that alar part cooperated.Yet, because must projecting light reflector internal diameter top, the formation dipped headlights just can reflex to nearer place, so block the projection of light for fear of insulated tube, after bulb and lamp socket are installed on reflector, must make insulated tube towards the below (as shown in Figure 5), use making light be projected to reflector from the top fully, the shade that reflector produced (shown in Fig. 5 chamfered region) of bulb below can't influence the projection of light.Otherwise after if bulb and lamp socket are installed on reflector, insulated tube is (as shown in Figure 4) towards the top, then will be subjected to insulated tube toward the light of top projection and block and produce shade (shown in Fig. 4 chamfered region), causes the brightness that influences dipped headlights.

The utility model content

The main purpose of the utility model is to provide a kind of lamp socket of the high-pressure discharge lamp that can install according to the specification of the automotive lighting lamp reflector of different labels, get so that after bulb is installed on the reflector of any specification by this lamp socket, the insulated tube of guaranteeing to be connected in bulb is positioned at the below of bulb, avoids influencing the brightness of dipped headlights because of insulated tube stops the projection of light.

Technological means of the present utility model, it is the alar part that is positioned at symmetric position in the setting of the edge of lamp socket body, and be provided with at the through hole edge of lamp socket should both wing portions and be positioned at two insulation pores of symmetric position, can make lamp socket be applicable to the reflector installation of any specification by this symmetrical alar part, and tube face can be installed on lamp socket at 180 degree both directions, and then guarantee that insulated tube is positioned at the below of bulb, avoid insulated tube to shut out the light and invest the reflector top and the irradiation brightness of reduction dipped headlights.
