Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1, Figure 3, the present invention provides a kind of automobile LED headlamp, including the first inner cover 1 and the second inner cover 2；The
One inner cover 1 and the second inner cover 2 are concave structure, specifically, may each be circular concave inward structure, circular concave inward structure herein
Refer to similar to bowl structure, but it should be noted that circle of the present invention etc. description be only that inventor surrounds shape to it
A kind of description of approximate shapes, be not the absolute geometric figure on mathematics geometric meaning, do not answer and narrow be interpreted as constituting
It is the shape of closing；Wherein, the one end of the first inner cover 1 is directly arranged in vehicle body, and its other end is fixedly connected with the second inner cover 2；
Because the second inner cover 2 is more than the first inner cover 1 so that the first inner cover 1 can be arranged in the second inner cover 2；Specifically, it is possible to understand that
It is concave structure of the whole concave structure of the second inner cover 2 more than the first inner cover 1；So allow in the first inner cover 1 and second
2 direct transition connections are covered, and forms different reflector spaces, while the main cause for so setting is that the second inner cover 2 is mainly used in
Headlamp outer shroud light source is provided, the first inner cover 1 is mainly used in providing the effect for strengthening outer shroud light source；Further, in improve
The intensity of outer shroud light source, as shown in figure 1, this automobile LED headlamp also includes interior wick；Wherein, interior wick includes the interior He of smooth core 3
Outer smooth core 4；Interior one end of smooth core 3 is fixed in the first inner cover 1, and its other end stretches out and without departing from the first inner cover 1；Further
Ground, interior wick 3 is cylindrical wick, and it can be distributed by the effect of the first inner cover 1, due to the indent knot of the first inner cover 1
The small easy reflection of structure, spotlight effect is preferable, it is possible to improve the utilization of light source, and outer smooth core 4 is spherical wick or elliposoidal lamp
Core；It should be further stated that interior light core 3 stretches out and without departing from the first inner cover 1, so can mainly make interior smooth core 3
Reflected using the first inner cover 1, at the same can make outer smooth core 4 just it is outwardly be arranged at one end that interior smooth core 3 stretches out, enter
The position of light core 4 belongs in the second inner cover 2 just outside one step ground, can so cause that outer light core 4 is anti-by light source by the second inner cover 2
It is shot out, and outer light core 4 sets globulate LED lamp core or elliposoidal LED lamp core and can improve the scattering of wick light source, so that
Improve brightness；The brightness of automobile headlamp light source can be effectively improved by using such scheme, simple structure, reliability, and
Do not hinder to install in limited streamline space.
Preferably, with reference to such scheme, as shown in Figure 1, Figure 3, automobile LED headlamp of the present invention also includes reflection unit,
Reflection unit is arranged in the second inner cover 2 by outer wick supporting rack 8, and reflection unit side is provided with reflecting surface, and opposite side is provided with recessed
Shape lampshade 6；Specifically, reflecting surface is convex reflecting surface 5 in the present embodiment, and convex reflecting surface 5 sets towards the first inner cover
Put；The back side of reflecting surface is provided with spill lampshade 6；Outer wick 7 is provided with spill lampshade 6, outer wick 7 can be spherical LED lamp core
Or elliposoidal LED lamp core；Its central light source for being mainly used in providing headlamp inner ring.Further, in order to reflection unit can
Play the light source that the first inner cover 1 of reflection is reflected back, it is to avoid the scattering light source of the outer light core 4 of interference；Convex reflecting surface 5 should be not more than
First inner cover 1, can so allow that convex reflecting surface 5 plays the reflection incoming light source of the first inner cover 1 just；Such as Fig. 3
It is shown, it is necessary to be explained further, convex reflecting surface 5 should be not more than the first inner cover 1 and can be understood as convex reflecting surface 5 herein
The area of whole reflecting surface should be not more than the cross section of the whole axial direction of first inner cover 1；It is anti-by what is be provided with using such scheme
Injection device, effectively can reflex to the second inner cover, so as to increase the light source of the second inner cover, it is to avoid preceding by the light source in the first inner cover
The not enough problem of illuminator outer shroud light-source brightness.
Preferably, with reference to such scheme, as shown in Figure 1, Figure 3, in the present embodiment, automobile LED headlamp of the present invention is also wrapped
Include outer wick supporting rack 8；One end of outer wick supporting rack 8 can be fixedly connected with the second inner cover 2, and its other end connects with reflection unit
Connect, so as to play being used as support reflection unit；And to avoid the jamming light source of outer wick supporting rack 8, the material of outer wick supporting rack 8
It is typically chosen as transparent material or trnaslucent materials is made, for example, can is made of makrolon；By using the such scheme can be with
Play a part of to support reflection unit, by the inner ring light source for keeping car headlamp.
Preferably, with reference to such scheme, in the present embodiment, the interior light core of automobile LED headlamp is cylindrical wick, its to
Outer to extend to concordant with the first inner cover, the light source on so cylindrical wick can be just scattered directly into the first inner cover so that instead
It is shot out, light source utilization rate is higher；Further, outer smooth core is spherical wick or elliposoidal wick, can so improve scattering
Effect.
Preferably, with reference to such scheme, as shown in Fig. 2 in the present embodiment, interior wick includes lamp socket 11, the one of lamp socket 11
End is arranged in the first inner cover 1, and the other end of lamp socket 11 stretches out and without departing from the first inner cover 1, it can be understood as lamp socket 11
Length in the first inner cover 1；And lamp socket 11 circumferentially on be uniformly provided with multiple small wicks 12, small wick 12 is uniformly in row
Shape or column-shaped install with lamp socket 11；Big wick 13 is provided with the end of lamp socket 11, in the same manner, big wick 13 is chosen as spherical lamp
Core or ellipsoid wick, such light source is larger and easily scatters；In the present embodiment, multiple small wicks are provided with by lamp socket,
The intensity of light source in the first inner cover can be effectively improved, it is to avoid the not enough problem of car headlamp outer shroud light source.
With reference to such scheme, correspondingly, the present invention also provides a kind of automobile；Wherein, the headlamp of automobile is described above
Automobile LED headlamp；This can improve the uniformity of automobile headlamp light source, improve automobile at night light lamp security, it is to avoid
Because light source deficiency causes safety problem.
By using above technical scheme, the uniformity of car headlamp inner and outer ring light source can be kept, it is to avoid outer shroud light
Source brightness not enough produces aberration, so as to be driven a vehicle between influenceing night dealing, improves security；There is provided by using the present invention simultaneously
Scheme, directly designed in automobile lampshade, structure is relatively simple, reliable, be easily installed；The streamline of automobile appearance is not influenceed to set
Meter.
The above, only presently preferred embodiments of the present invention not does any formal limitation to the present invention.It is any ripe
Those skilled in the art is known, in the case where technical solution of the present invention ambit is not departed from, all using technology contents described above
