Abstract

The utility model relates to a projective type vehicle headlight, which is composed of a lamp holder, a reflecting mirror surface, a lamp cover, a glass cover, etc., wherein, the reflecting mirror surface is arranged in the lamp holder; the lamp cover is connected with the lamp holder; the glass cover is arranged at the front of the lamp cover; the reflecting mirror surface is a multi-curved surface; a light distributing plate is arranged in the lamp cover; the glass cover is made of glass light collecting lens. Because the multi-curved surface reflecting mirror surface is composed of arc lengths with different radiuses R, the light distributing plate is arranged in the lamp cover, and the purpose-made light collecting glass lens is arranged at the front of the lamp cover, the utility model has the advantages that the light distribution performance and the focusing performance of the vehicle headlight are improved, and the vehicle headlight has good effect.

Description

The projection-type automobile headlamp

The utility model relates to auto lamp, particularly relates to automobile headlamp.

Various lamps are installed on the automobile, mainly are divided into illuminating lamp and signal lamp, automobile headlamp is most important a kind of illuminating lamp.Reflective mirror is the principal element that directly influences lighting effects in the lamp socket of headlight, and the geometry in the reflective mirror is a decisive factor.Existing automobile front reflective mirror is a parabolic shape, has defectives such as luminous intensity distribution performance difference.And anterior cloche spotlight effect is poor.

The purpose of this utility model is the defective that overcomes prior art, and particularly the structure to mirror surface and cloche makes improvements design, and a kind of luminous intensity distribution, projection-type automobile headlamp that the optically focused performance is good are provided.

The technical scheme of the utility model projection-type automobile headlamp is: by lamp socket, mirror surface in the lamp socket, the lampshade that connects lamp socket, being installed in cloche before the lampshade etc. forms, its so-called mirror surface is a curved surface more than, the luminous intensity distribution plate is installed in lampshade, and so-called cloche is a glass condenser.

Projection-type automobile headlamp of the present utility model, the many curved surfaces of its so-called speculum are distance light mirror multi-surface reflector face or dipped beam mirror multi-surface reflector face, the sweep R=20-1000 millimeter of the many curved surfaces of distance light mirror, the sweep R=5-350 millimeter of the many curved surfaces of dipped beam mirror, R is a lot of, from R ₁-R _n, the different radii of one section one section arc length is so be called many curved surfaces.

Projection-type automobile headlamp of the present utility model, its distance light mirror lamp socket and dipped beam mirror lamp socket are split or disjunctor.

The utility model is a kind of automobile headlamp, compared with the prior art, has following characteristics: the one, and the mirror surface in the lamp socket is many curved surfaces, has improved luminous intensity distribution performance; The 2nd, in lampshade, be shaped on the luminous intensity distribution plate, make the light distribution effect of mirror better; The 3rd, the anterior glass condenser of installing improves the optically focused performance; The 4th, but distance light mirror lamp socket and lamp socket split of dipped beam mirror or disjunctor use flexibility big.

Below in conjunction with Fig. 1-Figure 10 embodiment of the present utility model is done detailed explanation.

1,1 ', base plate; 2,2 ', lamp socket; 3, multi-surface reflector face; 4,4 ', glass condenser; 5, lampshade; 6, luminous intensity distribution plate; 7, connecting hole; 8,8 ', 9, connector; 10, peace bulb hole; 11, luminous intensity distribution plate; 12,12 ', fixture; 13, connector; 14, spirit level; 15, distance light mirror multi-surface reflector face; 16, dipped beam mirror multi-surface reflector face.

The utility model relates to automobile headlamp, have lamp socket 2,2 ' and lamp holder base plate 1,1 ', lamp socket 2,2 ' inwall are multi-surface reflector faces 3, each the position difference of the geometry radius R of multi-surface reflector face is bigger, as Fig. 4-shown in Figure 6 is the embodiment of a distance light mirror multi-surface reflector face 15, its minute surface sweep R minimum is 20 millimeters, and maximum is 1000 millimeters, from R ₁-R _nThe situation at a lot of places.Fig. 7-shown in Figure 9 is the embodiment of a dipped beam mirror multi-surface reflector face 16 for another example, and its minute surface curve R minimum is 5 millimeters, and maximum is the R=350 millimeter, from R ₂₁-R _2n, different everywhere, and described sweep R is maximum or minimum only is the concrete size of two embodiment, illustrates that sweep has nothing in common with each other everywhere, in production reality, perhaps lower limit is littler, and the upper limit is bigger.Lamp socket 2 connects lampshades 5, the front have glass condenser 4,4 ', be connected by fixture 12, so-called glass condenser is solid sphere, the radius SR of solid sphere is different everywhere.Be shaped on luminous intensity distribution plate 6,11 in the lampshade 5, outer wall be shaped on connector 8,8 ', 9.But distance light mirror and the split of dipped beam mirror, but also disjunctor, Fig. 3 is a conjoined structure, links to each other through connector 13, and spirit level 14 can be arranged, and is convenient to install.

Claims
