Description

Two optical lens projection lamps

Technical field

The utility model relates to a kind of auto parts machinery, is specifically related to a kind of automobile front that is used for automotive lighting.

Background technology

During the nighttime driving vehicle, when with another car meeting or when following in another car back, should use dipped headlights that suitable road lighting is provided, and the driver is dazzle the eyes, so dipped headlights should enlarge light district scope, high beam should make light concentrate.The reflector of existing automobile front is a single semiellipsoid, as makes dipped beam time district's wide ranges, and then spotlight effect will be poor during distance light; As spotlight effect is good when making distance light, and then dipped beam time district's scope is just wide inadequately, thereby all good requirements of effect can not satisfy distance light and dipped beam time of existing automobile front.

The utility model content

In order to overcome existing automobile front when the dipped beam, the deficiency of throw light effectively, the purpose of this utility model is: a kind of pair of optical lens projection lamp is provided, this lamp can be concentrated by light when distance light, effective light district expanded range during dipped beam can not cause the driver to dazzle the eyes, and guarantees driving safety, and can reequip existing automobile front, it is installed on the existing automobile Lamp cup, not only saves investment and simple installation, can carry out normalizing operation, convenient and swift.

The technical scheme that its technical problem that solves the utility model adopts is as follows:

A kind of pair of optical lens projection lamp, it comprises Lamp cup, reflector, light shield and convex lens.Described reflector comprises two 1/4 ellipsoids that differ in size, and these two ellipsoidal major axis are put relatively, and is integral molding structure by semi-circular brace butt joint; Opening part at reflector is equipped with a lens carrier, and convex lens are contained on this lens carrier; Light shield is sleeved on outside convex lens and the lens carrier; The bottom of reflector has lamp hole; The reflector that links together after the assembling, light shield, lens carrier and convex lens are fastenedly connected by be located by connecting mechanism and Lamp cup.

The described mechanism that is located by connecting that is fastenedly connected with Lamp cup comprises a centring ring, a retainer plate and an after-poppet, and be fixedly connected with a clamping ring in the bottom of reflector, on the cylindrical of this clamping ring, be provided with three raised lines, spacing between the raised line has nothing in common with each other, and respectively has a screw hole II in three raised lines; Be provided with three axial projection on described centring ring, the size and the spacing of these three projections have nothing in common with each other, the size of these three projections and position all with the interior circle of Lamp cup bottom outlet on the groove I that opened suitable; Also have three groove II on the interior circle of centring ring, three raised lines on the clamping ring cylindrical of these three groove II and reflector bottom are suitable; Described after-poppet is contained in the back of centring ring, has the screw hole I that three spacings do not wait on after-poppet, also has the through hole I that three spacings do not wait in the inboard of screw hole I, and the aperture of through hole I is less than the aperture of screw hole I; The size and the position of the screw hole II of being opened in three raised lines on the size of these three through hole I and position and the clamping ring cylindrical are identical; Between after-poppet and centring ring retainer plate is housed, has three through hole II on this retainer plate, size and the position of three through hole I on these three through hole II and the after-poppet are identical; Also have three blind holes on centring ring, the size and the position of three screw hole I on the size of these three blind holes and position and the after-poppet are identical.

Compared with prior art, the beneficial effects of the utility model are:

1, light is concentrated in the time of can making distance light, effective light district expanded range during dipped beam

Because the reflector in the utility model is to be combined by two ellipses that differ in size, and with little oval part, makes reflection ray more concentrated during distance light; With big oval part, make the light district scope of reflection wideer during dipped beam, wideer by 30% than existing single ellipsoid, make light fully project the effective visible sensation scope, can not produce the vision blind area, guarantee driving safety.

2, can on existing automobile front, reequip, convenient and swift

The utility model has designed with existing automobile front Lamp cup and has positioned the mechanism that is connected, make it to utilize existing Lamp cup to be reequiped, needn't all change, not only save investment, and according to the designed mechanism that is located by connecting of structure that has Lamp cup now, the position of the two relation and annexation all are unique, make simple installation, can carry out normalizing operation, convenient and swift.
