It is worth noting that in the present embodiment, the lens 3 are a planoconvex spotlight, in other changes of the present embodiment
Change in aspect, the lens 3 can also be that other refractive index are positive lens, such as：Biconvex lens.
The lens carrier 4 is used to support and fixes the lens 3.
The radiating piece 5 connects the lens carrier 4, and for radiating.
The reflecting element 6 is set on the radiating piece 5, and includes first focus far from the rear focus 33
61 and one it is neighbouring it is described after focus 33 and for the light of reflected ray by the second focus 62.
The reflecting element 6 relatively of the illuminating part 7 is set on the radiating piece 5, and the first of the neighbouring reflecting element 6 is burnt
Point 61, and emit light towards the reflecting element 6.
It is worth noting that the illuminating part 7 is the light emitting diode being made of at least one semiconductor wafer.
The setting of the raster unit 8 includes one and is hubbed on the lens between the lens 3 and the rear focus 33
On holder 4 and the lenticular lenses 81 that can be rotated.
Refering to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the lenticular lenses 81 are inverted U shape, and to visible wavelength 400nm~700nm's
Penetrance≤80%, and there are one the top surface 811 of the neighbouring optical axis X and two sides for being hubbed at the lens carrier 4 for tool
812.The top surface 811 and optical axis X is in an angle theta, and the angle theta can correspond to different dark space light shape designs, and adjust
Whole position and angle.
It is worth noting that in the present embodiment, the top surface 811 is plane, in other variation aspects of the present embodiment
In, the top surface 811 can also be as shown in figure 4, be the curved surface of a fovea superior, or as shown in figure 5, is a recessed curved surface.

The matte 9 is adjacent to the second focus 62 of the reflecting element 6, and for covering the light from the reflecting element 6
Line, for making the light projected by the lens 3 form "cut-off"line.
Refering to Fig. 3 and Fig. 6, the illuminating part 7 sends out multiple light, clear to describe, and light L1, light are only drawn out in figure
Line L2, light L3, light L4, light L5 and the representative light of light L6 six.
The light L1, the light L2, the light L3 and light L4 pass through institute after the reflection of the reflecting element 6
It states matte 9 towards the incidence surface 31 to advance, the light L1 is not through the lenticular lenses 81, so directly entering light described in incidence
Face 31, and projected by light-emitting surface 32 after the refraction of the lens 3.The light L2, the light L3 and the light L4 then enter
Penetrate the lenticular lenses 81.
At this point, the light L2 and light L3 represents the light that part is reflected by the lenticular lenses 81, the light
L2 via incidence surface 31 the portions incident positioned at the optical axis X or more, through the lens 3 refraction after, by the light-emitting surface 32
It projects.The light L3 is located at the optical axis X portions incidents below by incidence surface 31, after the refraction of the lens 3, by institute
State the injection of light-emitting surface 32.
It should be noted that the light L3 ' for indicate in the case of the raster unit 8 is not set, by it is described go out
The light that smooth surface 32 projects, it will be appreciated from fig. 6 that the light L3 and light L3 ' is although be equally anti-through the reflecting element 6
It penetrates, advances towards the matte 9, however, the separate optical axis X of the light L3 and light L3 ', the light L3 ',
The light L3 is projected because being reflected by the lenticular lenses 81, by light-emitting surface 32 close to the optical axis X, relative to described
For light L3 ', caused by dispersion situation it is smaller.
The light L4 represents the light not reflected by the lenticular lenses 81, and the light L4 is reflected through the lenticular lenses 81
Afterwards, it by being projected by the light-emitting surface 32 after the incident lens of the incidence surface 31 3, for the light L3, causes
Dispersion situation it is larger.
The light L5 then after the reflection of the reflecting element 6, advances, and covered by the matte 9 towards the matte 9.
The light L6 advances towards the radiating piece 5 and is reflected by the radiating piece 5, and by the screening after the reflection of the reflecting element 6
Piece 9 covers.The light L5 is covered with the light L6 by the matte 9, forms "cut-off"line (refering to Fig. 8).
The light shape gradient map of general car light is as shown in Figure 7, it can be seen that above "cut-off"line or near, light more divides
It dissipates, by the light shape gradient map of Fig. 8 the embodiments of the present invention, then can be clear that, due to setting for the raster unit 8
Set, make part by light reflected by the raster unit 8, reach reduce "cut-off"line near stray light and dispersion phenomenon
The effect of.Moreover, due to the light L2, the first half through the light-emitting surface 32 projects, and causes on "cut-off"line
The light shape of square dark space so that be easier to see the road sign (not shown) of upper pavement surface in driving, and meet and advise ECE in Europe
In R112 systems, the light distribution point in dark space (Zone III) complies with standard.
It is worth noting that the adjustment of the angle theta, can only influence the light shape of dark space, without influencing "cut-off"line
Neighbouring light shape.
Expansion details can be deduced from the description above due to having usually intellectual in this field, do not added
It is bright.
Via above explanation, the advantages of previous embodiment, can be summarized as follows：Pass through the lenticular lenses 81, reflective portion
The light reflected from the reflecting element 6 reaches and reduces stray light near "cut-off"line and the effect of dispersion phenomenon.More
Further, can be by adjusting the angle theta of the top surface 811 and the optical axis X of the lenticular lenses 81, to increase dark space
Brightness, make clearly see road sign in driving.
As described above, only the embodiments of the present invention, when the utility model implementation cannot be limited with this
Range, i.e., it is all according to simple equivalent changes and modifications made by the utility model claims book and description, all still belong to
The scope of the utility model.
