The specific embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.Same reference marks in description refers to same member.
Below in conjunction with the explanation accompanying drawing of the automobile lamp of the embodiment of the present invention, the present invention is described in detail.
Fig. 1 is the automobile lamp structure chart of one embodiment of the invention, and Fig. 2 is the part amplification assumption diagram of illustrated automobile lamp in Fig. 1.
The automobile lamp of one embodiment of the invention comprises aspherical lens 110, be disposed at the light source 120 of the distance more farther than the focal length of aspherical lens 110 from aspherical lens 110, be disposed between aspherical lens 110 and light source 120 and the light generating from light source 120 reflexed to the reflector 140 of aspherical lens focal length.
Aspherical lens 110 adopts the material of printing opacity to form.The shape of aspherical lens 110 does not limit, and according to luminous intensity distributions such as the centrality of light or dispersivenesses, can have various shape.Aspherical lens 110 generates from light source 120, and the light of launching from reflector 140 is distributed to automobile external.In the present embodiment, aspherical lens 110 can make the light of launching from reflector 140 directly enter.
Light source 120 is the machines that generate light.Light source 120 in the present embodiment is formed by multiple light emitting diodes (Light Emitting Diode).Multiple light sources 120 are accepted power supply from substrate 130.The configuration of being separated by substrate 130 of multiple light sources 120.Multiple light sources 120 in the plane vertical with the luminous intensity distribution direction of eyeglass, be separated by be configured to suitable.The light generating from light source 120 is all accommodated by reflector 140.
Multiple light sources 120 are disposed at than the farther distance of the focal length of aspherical lens 110 (L_f).Distance (L_r) from aspherical lens 110 to multiple light sources 120 is longer than focal length (L_f).
Reflector 140 reflexes to the light generating from light source 120 focal length (L_f) of aspherical lens.Reflector 140 is equipped with multiple, corresponding with multiple light sources 120.In other words, a light source 120 configures a reflector 140.
According to Fig. 2, reflector 140 is the variable drums of both-side opening internal diameter.One side of reflector 140 forms the first peristome 140a, and opposite side forms the second peristome 140b.The upper configuration of the first peristome 140a light source 120 of reflector 140, the second peristome 140b of reflector 140 and the focal length (L_f) of aspherical lens 110 arrange accordingly.
Reflector 140 is all accommodated the light generating from light source 120, is transmitted into the second peristome 140b.Light source 120 is that the light for generating is all accommodated by reflector 140, and the first peristome 140a that should insert reflector 140 is advisable.
Reflector 140 is the light total reflection generating from light source 120.The inner face forming curves of reflector 140 and the light that generates from light source 120 are reflected towards the second peristome 140b.Reflector 140 is inner face forming curves, and the drum variable by internal diameter forms.
The second peristome 140b of reflector 140 and the focal length (L_f) of aspherical lens 110 configure accordingly, therefore from reflector 140 reflect or light by reflector 140 all towards aspherical lens 110.
According to embodiment, the upper configuration of the focal length of aspherical lens (L_f) LGP 150.LGP 150 configures accordingly with multiple second peristome 140b of multiple reflectors 140.A LGP 150 forms and configures to cover the mode of multiple the second peristome 140b.
LGP 150 is all guided to aspherical lens 110 the light of launching from the second peristome 140b of multiple reflectors 140.LGP 150 can all gather the light of launching from the second peristome 140b of multiple reflectors 140 focus of aspherical lens 110.
According to embodiment, LGP 150 is guided to the light of launching from the second peristome 140b of multiple reflectors 140 bottom of aspherical lens 110, light is distributed in bottom by aspherical lens 110.
Below in conjunction with Fig. 3 and Fig. 4, the effect that the automobile lamp of one embodiment of the invention is brought into play is described.
Fig. 3 is the part running figure of illustrated automobile lamp in Fig. 1, and Fig. 3 is the running figure of illustrated automobile lamp in Fig. 1.
According to Fig. 3, the light generating from light source 120 is all accommodated by reflector 140, towards the inner face of reflector 140, or towards the second peristome 140b.Towards the light of reflector 140 inner faces in inner face reflection and towards the second peristome 140b.
Reflect or all accommodated by LGP 150 by the light of multiple reflectors 140 from multiple reflectors 140.In other words the light of launching from the second peristome 140b of multiple reflectors 140, is all accommodated by LGP 150.
According to Fig. 4, the light of being accommodated by LGP 150 is all introduced to aspherical lens 110.What be introduced to aspherical lens 110 is only directly entered distribution.According to embodiment, the light of being accommodated by LGP 150 is introduced to the bottom of aspherical lens 110, is distributed directly in the bottom of aspherical lens 110.
Above preferred embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in aforementioned each embodiment, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of technical scheme described in various embodiments of the present invention.
