Description
Technical field
The present invention is new to be related to a kind of lighting device.
Background technology
Vehicle light illumination device is one of essential auto parts machinery, and car light is typically by by main light source and secondary light source
It is arranged at main anti-and secondary mirror back focus position, although can be by light closer to optical axis, but optical fiber is equal
Evenness and saturation degree will be not enough because light cannot be concentrated, and have impact on the accuracy of light, and with the electricity of LED
Energy conversion ratio, only percent 15-20 is converted into luminous energy, and percent 80-85 is converted to heat energy, and LED
Temperature rises will be caused to light and can fail, wherein it is again most notable with gold-tinted recession level, if being taken the photograph with yellow light LED
25 degree of family name is promoted to 100 degree, and its fading rate is up to percent 75, the property that this will be significantly influence LED luminous
Energy and stability, if maintaining the luminous efficacy of LED, certainly will provide good radiating efficiency to reduce thermal balance.
Therefore those skilled in the art are devoted to a kind of photograph that can improve automobile main light source extremely secondary light source of exploitation
Bright lamp has.
Invent new content
In view of the drawbacks described above of prior art, the new technical problem to be solved of the present invention is to provide one kind
The illuminator of automobile main light source extremely secondary light source can be improved.
To achieve the above object, the present invention is new there is provided a kind of lighting device, including the first lamp socket, second
Lamp socket, lens and reflective mirror, are provided with the first speculum on lamp socket, the first speculum is in false ellipse shape,
First focus and the second focus are formed with optical axis, and the first light source is provided with the first focus, with reflective mirror
Correspondence sets only the second speculum, and the second speculum ovalize shape, the second speculum forms the 3rd focus,
3rd focus and lens homonymy, secondary light source is provided with the second lamp socket.
Lighting device as claimed in claim 1, the first light source is diode LED.
The new beneficial effect of the present invention is：The present invention is new can to improve illumination intensity and extension illumination life-span,
With simple structure, the low beneficial effect of cost.
Brief description of the drawings
Fig. 1 is the structural representation of the new specific embodiment of the present invention.
Specific embodiment
It is new to the present invention with reference to the accompanying drawings and examples to be described further：
As shown in figure 1, a kind of lighting device, including the first lamp socket 22, the second lamp socket 42, lens 1 and anti-
Light microscopic 3, is provided with the first speculum 2 on lamp socket 22, the first speculum 2 is in false ellipse shape, with optical axis
AX forms the first focus FP1 and the second focus FP2, and the first light source 21 is provided with the first focus FP1,
It is corresponding with reflective mirror 3 to set only the second speculum 4, the ovalize shape of the second speculum 4, the second speculum
4 form the 3rd focus FP3, the 3rd focus FP3 and the homonymy of lens 1, and second is provided with the second lamp socket 42
Light source 41.First light source 21 is diode LED.
Optical axis AX sides set the first speculum 2, and the arc-shaped of the first speculum 2 is formed with optical axis AX
First focus FP1 and the second focus FP2, and the first light source 21 is provided with the first focus FP1,
Lens 1 are projected to after the light L1 of first light source 21 is closed at into the second focus FP2, first light source 21 is hair
Two grades of bodies of light, the another sides of optical axis AX are obliquely installed correspondence reflective mirror 3 by optical axis AX, and the reflective mirror 3 is correspondingly arranged
Second speculum 4, second speculum is in oval arcuation, and the second speculum 4 forms two focuses, Jiao
Point is the 3rd focus FP3, and another focus is concurrent with the second focus FP2, and it is saturating that the 3rd focus FP3 is located at this
The homonymy of mirror 1, the 3rd focus FP3 is provided with secondary light source 41, and drop drop youngster light source 41 is light-emittingdiode, instead
Light microscopic 3 projects lens 1 after the light L2 of secondary light source 41 is closed at into the second focus FP2.
Set towards the first focus FP1 directions along optical axis AX by the second focus FP2, to cover the first light source 21
Lens 1 cannot be projected to.Present apparatus dipped headlight state, is focus light extraction by the optical property of ellipse, through ellipse
After reflection, light will be by another focus, so as to the first speculum 2 in the present apparatus is arranged into ellipse
Shape, and in the first focus FP1 and the second focus FP2 of optical axis AX the first speculums 2 of formation, and the first light
Source 21 be located at the first focus FP1, after light source L1 is through the first speculum 2, the second focus is closed at shoulder to shoulder
FP2, and be located at optical axis AX, therefore the reflection source L1 of the first speculum 2 by the second focus FP2, will be with
Optical axis AX lower sections are projected to the light extraction of lens 1, and then form the state of high beam, and the reflective mirror 3 is by the
Two focus FP2 are extended, and the light L2 of the second speculum 4 are closed at into the second focus FP2, by reflective
Mirror 3 is by light L2 towards the best optically focused corner reflection of lens 1, so that the luminance of the present apparatus is improved, it is reflective
Mirror 3 is extended by shadow shield 5, can save the manufacturing cost of shadow shield 5 and its reflective mirror 3.
First light source 21 and secondary light source 41 are light-emittingdiode, to avoid the first light source 21 and secondary light source
41 are mutually heated and influence its luminance, Gu and the first lamp socket 22 is to set to be located at relative lens along optical axis AX
1 one end, and the side of the second lamp socket 42 is located at the homonymy of lens 1, extends the first lamp socket 22 and the second lamp socket
42 spacing, and then the first light source 21 and the luminous produced heat energy of secondary light source 41 are reduced with heat transfer or spoke
Penetrate and influence each other, so as to effectively maintain the luminous efficiency of the first light source 21 and secondary light source 41.
The new preferred embodiment of the present invention described in detail above.It should be appreciated that this area is common
Technical staff just can make many modifications and variations without creative work according to the new design of the present invention.
Therefore, all technical staff in the art pass through on the basis of existing technology according to the new design of the present invention
The available technical scheme of logical analysis, reasoning, or a limited experiment, all should be by claims institute
In the protection domain of determination.
