The present invention is achieved through the following technical solutions above-mentioned technical purpose:
A reflector for electrocar lamp module, described reflector comprises reflector; Described reflector is ellipsoid planar; The bottom of described reflector is opening; The arc rim of a cup of the described reflector light path port of export is provided with the shirt rim to turning up; One end that described reflector is relative with the described light path port of export extend horizontally away the second fixed head to the ejecting end away from light; Described second fixed head thickness direction is provided with screw.
Preferably, described reflector is 1/4 ellipsoid.
Preferably, the both sides of described reflector are vertical sidewall.
Preferably, described reflector inner wall smooth.
Preferably, described shirt rim is vertical with described second fixed head.
Prior art of the present invention is compared, and has the following advantages:
Namely the reflector of ellipsoid planar, also the reflecting surface of reflector is made up of single ellipsoid, and the reflector adopting single curved surface to make is easy to machine-shaping, is reflected and the light type that presents is even simultaneously, improve the light-out effect of car light by ellipsoid.

Detailed description of the invention
For making to have a better understanding and awareness architectural feature of the present invention and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As shown in Figure 1, a kind of reflector of electrocar lamp module, it is applied to electrocar lamp pattern, and this electrocar lamp module comprises lens subassembly, radiator 2, reflector 3, keyset 4, dipped headlights pearl plate 5, high beam pearl plate 6, lamp pearl 7.
As shown in Figure 2, lens subassembly is sleeve lens 1; Sleeve lens 1 comprise planoconvex spotlight 11 and sleeve 12 integrated with planoconvex spotlight 11.Planoconvex spotlight 11 one side is the plane of incidence of plane light, and another side is the convex surface for light injection.Sleeve 12 extends to the side away from planoconvex spotlight 11 from the plane of planoconvex spotlight 11.Sleeve 12 is provided with outside flange 13 away from one end of plane, and flange 13 is parallel with plane.The contour shape of flange 13 can design according to actual needs.A pair symmetry is extended and the first parallel fixed head 14 along sleeve 12 axis direction in the both sides of flange 13; First fixed head 14; First fixed head 14 is vertical with flange 13; First fixed head 14 thickness direction is provided with screw 141.
In order to make translucent effect better, sleeve lens 1 provided by the invention are of a size of: sleeve 12 external diameter is 26mm, convex surface summit to the vertical range of plane is 7.72mm, plane to flange 13 away from the sidewalls orthogonal distance of the side of planoconvex spotlight 11 be 15.08mm, land edges to the vertical range of flange near the side of plane be 13.09mm, flange 13 thickness is 2mm.So little size, if lens and sleeve separation design, is easy to cause installation deviation, and situation unstable after installation occurs.
Flange 13 profile of sleeve lens 1 provided by the invention is rectangle substantially, also according to actual needs, can be designed to other contour shape.Also according to external structure situation, flange 13 can design the positioning convex that some coordinate with external structure, 131 as shown in Figure 1, Figure 2.
As shown in Figure 3, reflector 3 comprises reflector 31; Reflector 31 is ellipsoid planar.The bottom of reflector is opening; The arc rim of a cup of the reflector 31 light path port of export is provided with the shirt rim 32 to turning up; The other end of reflector 31 extend horizontally away the second fixed head 33 to the ejecting end away from light; Second fixed head 33 thickness direction is provided with screw 331.
Reflector 31 provided by the invention is 1/4 ellipsoid of ellipsoid, its inner wall smooth, and shirt rim 32 is vertical with the second fixed head 33.
As shown in Figure 4, Figure 5, electrocar lamp module also comprises radiator 2; Radiator 2 comprises upper bed-plate 21, fixes splintery fin 22 below upper bed-plate 21, has gap, with increasing heat radiation area between adjacent two fin 22.Upper bed-plate 21 relevant position of radiator 2 is provided with the first screw 211.Reflector 31 is fixed on the top of radiator 2 successively through screw 331, first screw 211 on the second fixed head 33 by screw.Reflector 31 shirt rim 32 after fixing is in same plane with the end face of radiator 2.The both sides, one end of radiator 2 are provided with the second screw 212, and the inwall spacing between two piece of first fixed head 14 of sleeve lens 1 is equal with the width of radiator 2.Sleeve lens 1 are fixed on one end of radiator 2 successively through screw 141, second screw 212 on the first fixed head 14 by screw.The flange 13 of the sleeve lens 1 after fixing is fitted with shirt rim 32, the section of radiator 2 near one end of sleeve lens 1 respectively.Radiator 2, reflector 3, sleeve lens 1 three form a cavity.
The size dimension of reflector 31 is different according to the actual needs difference of car light.Reflector both sides provided by the invention are part cup by vertical cut, and the cavity that radiator 2, reflector 3, sleeve lens 1 three are formed not is closed.Because the part cup be cut is reflector space edge, so on the whole, this change for cup does not affect actual illumination effect.
Radiator 2 provided by the invention is aluminum alloy material.Certainly, the material of other good heat dissipation effect also can be adopted to make radiator 2 of the present invention.
Certainly, LED module can't do without keyset 4.Keyset 4 is fixed on the one end away from sleeve lens 1 on radiator 2 top and is in outside cavity.Keyset 4 is fixed by screws on the upper bed-plate 21 of radiator 2.
That carries out being electrically connected with keyset 5 has lamp pearl plate.Lamp pearl is arranged on lamp pearl plate.Dipped headlights pearl plate 5 and high beam pearl plate 6 are arranged in same sleeve lens 1 by the present invention.The upper bed-plate 21 that dipped headlights pearl plate 5 is fixed on radiator 2 is in cavity.High beam pearl plate 6 is fixed on radiator 2 and is on the end face of one end in cavity.Dipped headlights pearl plate 5 provided by the invention and high beam pearl plate 6 are all be fixed by screws on radiator 2.Certainly, the additive method that can realize fixing object is also contained in the present invention.
In specific works, if connect the power supply of dipped headlights pearl plate 5; Dipped headlights pearl is luminous, and the reflector 31 of dipped headlights pearl reflects the rear planoconvex spotlight 11 that passes and penetrates.Due to the design of planoconvex spotlight 11 special size, yes, the light of injection is more even.If connected the power supply of high beam pearl plate 6, high beam is luminous, and the light of high beam directly penetrates through planoconvex spotlight 11, same reason, and due to the planoconvex spotlight 11 of special size provided by the invention, make the distance light of injection more even, driving is experienced better.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
