Further, as shown in Figure 1, this dipped beam group 00 can also comprise: heat sink 007, and heat sink 007 for having the metal of high thermal conductivity, and heat sink 007 can conduct to outside this object fast by with the heat of this heat sink 007 object contacted.Optionally, this is heat sink 007 can be fixedly installed on light source base 003 away from the face of this reflective mirror 001, when the opening part on this light source base 003 is through hole, the face be positioned at away from this reflective mirror 001 on the bottom of the LED light source 002 of this opening part and this light source base 003 is coplanar, now, this is heat sink 007 bottom that can be arranged on this LED light source 002, makes heat sink 007 directly to contact with this LED light source, improves heat-conducting effect.Heat sink 007 can comprise multiple fin (not shown in figure 1), the direction arrangement that the plurality of fin flows according to air, heat sink 007 after the heat of deriving this LED light source 002, can to dispel the heat fast to make this.Further, this is heat sink 007 surface can scribble thermal dispersant coatings, to improve the radiating effect of heat sink 007, in order to alleviate the weight of this dipped beam group 00, this is heat sink 007 material can be the aluminium alloy of lighter in weight.
As shown in Figure 3, in order to meet the dipped beam light distribution requirements of automobile when driving safely, when the light that this LED light source sends reflects on this reflective mirror 001, after most light (the light U as in Fig. 3) is reflected by this reflective mirror 001, reflection ray is through the second focal point F 2 of this reflective mirror 001, arrive the inner plane 0061 of these lens 006, and refracted to outside these lens 006 by these lens 006.When the light that this LED light source sends reflects on this reflective mirror 001, a fraction of light (the light V as in Fig. 3) is reflexed in the shading surface 0051 of this shading element 005 by this reflective mirror 001, and continued the light reflection that reflected by this reflective mirror 001 inner plane 0061 to these lens 006 by this shading surface 0051, and refracted to outside these lens 006 by these lens 006.
As shown in Figure 4, if this dipped beam group 00 along this reflective mirror 001 to the direction of these lens on a photometric screen 01 is set, then most of light (the light U as in Fig. 3) of sending of this LED light source at this after the reflection of this reflective mirror 001 and lens 006 refraction, can arrive on this photometric screen 01, this photometric screen 01 is formed dipped beam district L1 (as shown in the dash area in Fig. 4).The sub-fraction light (the light V as in Fig. 3) that this LED light source sends at this after this reflective mirror 001 and the reflection of this shading surface 0015 and lens 006 refraction, can arrive this photometric screen 01 Shang Fei dipped beam district (not shown in Fig. 4), this non-dipped beam district is the region on this photometric screen 01 except dipped beam district L1.The light distributing method that the embodiment of the present invention provides meets the dipped beam light distribution requirements of automobile when driving safely.
Further, in prior art, adopt halogen light source as the light source of dipped beam group, because the light source energy consumption of halogen light source is higher, and the life-span is shorter, and often need to change the light source in dipped beam group, therefore, the use cost of dipped beam group is higher.Adopt LED light source as the light source of this dipped beam group in the dipped beam group that the embodiment of the present invention provides, example, LED light source only needs 10W (watt) just can provide required dipped beam for automobile, the energy consumption of LED light source is only 20% of halogen light source, and along with the raising of LED light source performance, LED light source also has the possibility reducing energy consumption further.Due to LED light source, to have energy consumption low, the advantage that the life-span is long, changes, so decrease the use cost of dipped beam group without the need to frequent to the light source in dipped beam group.
In sum, due in the dipped beam group that the embodiment of the present invention provides, by arranging LED light source, the reflecting surface of the reflective mirror that LED light source is corresponding is concave spherical surface, and this concave spherical surface is a part for spheroid, due to the small volume of this LED light source, and the spectral region of LED light source is narrower, make the area of the reflecting surface for reflecting the light that this LED light source sends, be less than or equal to 1/4th of this spheroid surface area, accordingly the small volume of this reflective mirror, the small volume of dipped beam group, so, reduce the space that this dipped beam group takies.
Above-mentioned all alternatives, can adopt and combine arbitrarily formation optional embodiment of the present invention, this is no longer going to repeat them.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
