Abstract
A kind of motorcycle headlamp optical system, comprise LED light source, light-guiding pillar and reflector, light-guiding pillar is cylindrical, its plane of incidence is corresponding with LED light source, its exit facet center is recessed to form curved reflecting surface to plane of incidence direction, be provided with through hole in the middle of reflector, reflector is enclosed within outside light-guiding pillar by described through hole.Utility model works principle: the light major part that LED light source sends enters in light-guiding pillar by the plane of incidence, and reflect at light-guiding pillar medial surface, make light reflection on curved reflecting surface, curved reflection face can by light reflection on reflector, and light is forwards reflected away formation hot spot by last reflector.The utility model adds light-guiding pillar in headlamp optical system, light-guiding pillar can guide the path of light, make it concentrate on to penetrate somewhere, so, contribute to the design of optical system, improve the utilization rate of light, conveniently can adjust the reflection angle of light on reflector, make its bright dipping evenly.
Description
Technical field
The utility model relates to field of LED illumination, especially a kind of motorcycle headlamp optical system.
Background technology
Current motorcycle headlamp optical system is fairly simple, generally only includes reflector and LED light source, and the light that LED light source sends is reflected away by reflector and forms front illumination spot.Although this kind of optical system is simple, its light efficiency is poor, and the utilization rate of light is low.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of motorcycle headlamp optical system, and light efficiency is good, and the utilization rate of light is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of motorcycle headlamp optical system, comprise LED light source, light-guiding pillar and reflector, described light-guiding pillar is cylindrical, its plane of incidence is corresponding with LED light source, its exit facet center is recessed to form curved reflecting surface to plane of incidence direction, and be provided with through hole in the middle of described reflector, described reflector is enclosed within outside described light-guiding pillar by described through hole.Utility model works principle: the light major part that LED light source sends enters in light-guiding pillar by the plane of incidence, and reflect at light-guiding pillar medial surface, make light reflection on curved reflecting surface, curved reflection face can by light reflection on reflector, and light is forwards reflected away formation hot spot by last reflector.The utility model adds light-guiding pillar in headlamp optical system, light-guiding pillar can guide the path of light, make it concentrate on to penetrate somewhere, so, contribute to the design of optical system, improve the utilization rate of light, conveniently can adjust the reflection angle of light on reflector, make its bright dipping evenly; In addition, because light-guiding pillar is simple with coordinating of reflector, arbitrarily can change reflector as required, then can be realized the adjustment of light efficiency by the position of adjustment light-guiding pillar, convenient and swift.
As improvement, the plane of incidence of described light-guiding pillar is provided with the groove for accommodating described LED light source.
As improvement, described reflecting surface is positioned at reflector focus place.
As improvement, described LED light source, light-guiding pillar and reflector are fixed on mount pad.
The beneficial effect that the utility model is compared with prior art brought is:
The utility model adds light-guiding pillar in headlamp optical system, light-guiding pillar can guide the path of light, make it concentrate on to penetrate somewhere, so, contribute to the design of optical system, improve the utilization rate of light, conveniently can adjust the reflection angle of light on reflector, make its bright dipping evenly; In addition, because light-guiding pillar is simple with coordinating of reflector, arbitrarily can change reflector as required, then can be realized the adjustment of light efficiency by the position of adjustment light-guiding pillar, convenient and swift.

Fig. 1 is the schematic diagram that light-guiding pillar coordinates with reflector.
Fig. 2 is light-guiding pillar and reflector sectional view.
Fig. 3 is the decomposition view of light-guiding pillar and reflector.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figures 1 to 3, a kind of motorcycle headlamp optical system, comprises LED light source, light-guiding pillar 2 and reflector 1.Described light-guiding pillar 2 is cylindrical, comprises the plane of incidence 6 being positioned at light-guiding pillar 2 one end and the exit facet being positioned at light-guiding pillar 2 other end; Light-guiding pillar 2 plane of incidence 6 is corresponding with LED light source, and the plane of incidence 6 of described light-guiding pillar 2 is provided with the groove 3 for accommodating described LED light source, and the light that LED light source can emit by this groove 3 is collected in light-guiding pillar 2 as much as possible; Light-guiding pillar 2 exit facet center forms curved reflecting surface 5 to the plane of incidence 6 direction depression 4, and described reflecting surface 5 is positioned at reflector 1 focus place, and the light in light-guiding pillar 2 can not directly penetrate through reflecting surface 5, can only be reflected by light by this reflecting surface 5.Be provided with through hole 7 in the middle of described reflector 1, described reflector 1 is enclosed within outside described light-guiding pillar 2 by described through hole 7, and described LED light source, light-guiding pillar 2 and reflector 1 are fixed on mount pad, and reflector 1 can arbitrarily be changed.
Utility model works principle: the light major part that LED light source sends enters in light-guiding pillar 2 by the plane of incidence 6, and reflect at light-guiding pillar 2 medial surface, make light reflection on curved reflecting surface 5, curved reflection face can by light reflection on reflector 1, and light is forwards reflected away formation hot spot by last reflector.The utility model adds light-guiding pillar 2 in headlamp optical system, light-guiding pillar 2 can guide the path of light, make it concentrate on to penetrate somewhere, so, contribute to the design of optical system, improve the utilization rate of light, conveniently can adjust the reflection angle of light on reflector 1, make its bright dipping evenly; In addition, because light-guiding pillar 2 is simple with coordinating of reflector 1, can arbitrarily change reflector 1 as required, then can be realized the adjustment of light efficiency by the position of adjustment light-guiding pillar 2, convenient and swift.
