Fig. 1, Fig. 2 shows a kind of light filling components 10 provided in an embodiment of the present invention, as shown in Figure 1 and Figure 2, including:
Pellicle mirror 11, pellicle mirror include reflecting surface 111 and transmission plane 112, and wherein incident ray 1 reflects to form anti-through reflecting surface 111
It penetrates light 2 and enters camera module for shooting；Supplementary lighting sources 12 are set to 112 side of transmission plane of pellicle mirror 11, light filling light
The transmitted ray 4 that the light filling light 3 in source 12 is formed through the transmission of transmission plane 112 is parallel and contrary with incident ray 1.
By pellicle mirror 11, the light of the target of shooting is enabled to pass through the reflection of reflecting surface 111, into camera mould
Group 20, meanwhile, the light filling light 3 for light filling can penetrate pellicle mirror 11 from transmission plane 112, it is radiated in the target of shooting,
Due to the setting of the light filling component 10 of the disclosure, enable to the transmitted ray 4 for light filling coaxial, parallel with incident ray 1,
So that the image that the target of shooting obtains will not generate " yin-yang " effect.And light filling light 3 is the light being parallel to each other, light
It concentrates, it can be can also reach stronger light filling effect in the shooting of the remote target of centering.
In one example, the reflecting surface 111 of pellicle mirror 11 is ellipse, and is set as in 2 side of incident ray 1 and reflection light
To projection be circle.When being shot by the light filling component 10 of the disclosure, incident ray needs to reflect, and camera
Camera lens is generally circular in cross section, and therefore, the reflecting surface 111 of pellicle mirror 11 is ellipse, and according to practical incident ray 1 and reflected light
The angle of line 2 guarantees that the projection for the light for reflecting into camera is rounded so that reflecting surface 111 is projected as circle, guarantees to clap
Take the photograph effect.

Reflectivity can be 70%, or higher, such as 80%.
In one example, the transmission plane 112 of pellicle mirror 11 is equipped with anti-reflection film, is greater than or equal to the transmissivity of transmission plane 112
70%.Anti-reflection film, which is arranged, by the transmission plane 112 in pellicle mirror 11 makes most of benefit to improve the transmissivity of transmission plane 112
Light light 3 projects photographic subjects after the transmission of pellicle mirror 11, and anti-reflection film can be arranged by way of pad pasting or plated film.Thoroughly
The rate of penetrating can be 70%, or higher, such as 80%.
Fig. 3 shows the supplementary lighting sources 12 of one embodiment of the invention offer, as shown in figure 3, in one example, supplementary lighting sources 12
Including point light source 121 and convex lens 122,5 planoconvex lens 122 of source light that point light source 121 issues form light filling light 3, mend
Light light 3 is parallel to each other.Light refraction property based on convex lens 122, the light that point light source 121 issues is reflected, shape
At parallel rays, the effect of optically focused is played, guarantees can also there be good light filling effect when shooting the target of medium and long distance.
According to actual size and light source, rectangle or circular array can also be formed using multiple light sources, to the transmission plane of pellicle mirror 11
112 send directional light.It can also be by other sources of parallel light as supplementary lighting sources 12.
In one example, wherein point light source 121 is LED light.LED light has the characteristic of highlighted low temperature low-power consumption, can be fine
Adaptation supplementary lighting sources 12 working environment.
Fig. 4 show another embodiment of the present invention provides a kind of light filling component 10, as shown in figure 4, in one example,
In, light filling component 10 further includes shell 13, and shell 13 connects pellicle mirror 11 and supplementary lighting sources 12 form cavity 131, transmission plane 112
Positioned at 131 side of cavity.13 one side of shell can play installation fixed function, guarantee between pellicle mirror 11 and supplementary lighting sources 12
Positional relationship, while also can be reduced supplementary lighting sources 12 sending light and 1 part of incident ray through pellicle mirror 11 entrance
The spilling of light in cavity 131 reduces the influence shot to camera module 20.
In one example, wherein 13 medial surface of shell uses light absorbent.Wherein, light absorbent can be the cloth of black
Or the material of other rough materials.The light being further reduced in cavity 131 overflows, and guarantees shooting effect.
Based on same design, the disclosure also provides a kind of picture shooting assembly 100, and Fig. 5 shows the embodiment of the present invention and mentions
A kind of picture shooting assembly 100 supplied, as shown in figure 5, including: camera module 20, for shooting image；Aforementioned any implementation
The light filling component 10 of example, reflection light 2 of the incident ray 1 after the reflection of light filling component 10 enter camera module 20.
The light of the target of shooting enters camera module 20 by light filling component 10, according to previous embodiment, it is specific and
Speech, is reflected into camera module 20, to shoot image, together by the reflecting surface 111 of the pellicle mirror 11 of light filling component 10
When, when environmental condition needs light filling, the pellicle mirror 11 that light filling light 3 passes through light filling component 10 forms transmitted ray 4 and is irradiated to
In target, thus to target light filling.The light filling of this kind of mode can effectively avoid shooting image from yin-yang situation occur.
In one example, incident ray 1 is vertical with reflection light 2.By the position that pellicle mirror 11 and camera module 20 is arranged
It sets, makes the lens plane of 11 plane of pellicle mirror and camera module 20 in 45 degree, this kind setting can facilitate installation and debugging, guarantee
The two angle avoids light and camera lens by reflection from generating angular deviation.
