It is appreciated that when it is plane mirror to turn optical element 22, the reflection of generation incident light is realized that incident light turns to by plane mirror.

In one example, Fig. 6 and Figure 12 are please referred to, turns optical element 22 with incidence surface 222, shady face 224, reflective surface 226 and light-emitting surface 228.Incidence surface 222 close to and towards light inlet 211.Shady face 224 is far from light inlet 211 and and incidence surface 222 is opposite.Reflective surface 226 connects incidence surface 222 and shady face 224.Light-emitting surface 228 connects incidence surface 222 and shady face 224. Reflective surface 226 is obliquely installed relative to incidence surface 222, and light-emitting surface 228 is disposed opposite to each other with reflective surface 226.

Specifically, in the transfer process of light, light, which passes through light inlet 211 and entered by incidence surface 222, turns optical element 22 In, then via the reflection of reflective surface 226, finally reflected from light-emitting surface 228 and turn optical element 22, the process of light conversion is completed, and Shady face 224 is fixedly installed with mounting base 23, is keeping stablizing so as to turn optical element 22.

Fig. 6, Figure 13 and Figure 14 are please referred to, in another example, it includes reflective surface 226, reflective surface 226 to turn optical element 22 For will be turned to from the incident incident light of light inlet 211, the incident light after steering reaches first after the first Lens assembly 24 Imaging sensor 26.First Lens assembly 24 includes eyeglass light inlet 242, projection of the eyeglass light inlet 242 on reflective surface 226 243 contour shape is identical as the contour shape of reflective surface 226.

It note that " projection " herein refers to entering light from eyeglass with the light parallel with the optical axis of the first Lens assembly 24 Mouth 242 is projected to reflective surface 226 and the shades of formation.Eyeglass light inlet 242 is that the first Lens assembly 24 enters first for light Opening in Lens assembly 24.

In fig. 14, the contour area of reflective surface 226 is equal to the contour area of projection 243.In some other embodiment party In formula, the contour area of reflective surface 226 is more than the contour area of projection 243, as shown in figure 15.

Specifically, the profile of reflective surface 226 can be oval, and the profile of eyeglass light inlet 242 can be rounded.It can manage Solution, since reflective surface 226 is obliquely installed relative to light-emitting surface 228, the rounded eyeglass light inlet 242 of profile is in reflective surface 226 On projection 243 contour shape it is oval, the contour shape of projection 243 of the eyeglass light inlet 242 on reflective surface 226 with The contour shape of reflective surface 226 is identical, and therefore, the profile of reflective surface 226 is oval.

In this way, the wheel of the contour shape and reflective surface 226 of projection 243 due to eyeglass light inlet 242 on reflective surface 226 Profile shape is identical, while ensure that turning optical element 22 works normally, can to turn the volume of optical element 22 as much as possible It is small, be conducive to the miniaturization of the first camera module 20, CCD camera assembly 100 and electronic device 1000.

It is appreciated that region of the reflective surface 226 in addition to projection 243 of the eyeglass light inlet 242 on reflective surface 226, compared with It less or can not reflection light.Therefore, on turning optical element 22, projection 243 of the eyeglass light inlet 242 on reflective surface 226 is removed The eliminating of region in addition will not cause to turn optical element 22 and can not work normally.Moreover, can so to turn 22 body of optical element Long-pending diminution, so that the volume smaller of the first camera module 20.

As shown in figure 16, in the related art, due to the needs of reflection incident ray, turn the reflective surface of optical element 22a 226a is tilted relative to horizontal direction, and it is unsymmetric structure to turn optical element 22a on the reflection direction of light, thus turns light member The opposite practical optical area turned above optical element 22a in the lower section of part 22a is smaller, it can be understood as, the part far from light inlet Reflective surface 226a is less or can not reflection light.

Therefore, please join Figure 17, the application embodiment turn optical element 22 relative in the related technology turn optical element 22a The corner angle far from light inlet have been cut off, has not only also reduced and turns without the effect for the reflection light for influencing to turn optical element 22 in this way The integral thickness of optical element 22.

In some embodiments, reflective surface 226 is tilted relative to the angle [alpha] of incidence surface 222 in 45 degree.

In this way, making incident light preferably reflection and conversion, has preferable light conversion effect.

Turn optical element 22 the relatively good material of the translucency such as glass, plastics may be used to be made.In one embodiment, It can turn the reflectorized materials such as one of optical element 22 surface silver coating to reflect incident light.

In some embodiments, incidence surface 222 is arranged in parallel with shady face 224.Specifically, entering along light inlet 211 Light direction, the section for turning optical element 22 is substantially trapezoidal, in other words, turns the substantially trapezoidal body of optical element 22.

In some embodiments, incidence surface 222 and shady face 224 are each perpendicular to light-emitting surface 228.

In this way, can be formed it is more regular turn optical element 22, keep the light path of incident ray more straight, improve turning for light Change efficiency.

In some embodiments, the distance range of incidence surface 222 and shady face 224 is 4.8-5.0mm.

Specifically, the distance between incidence surface 222 and shady face 224 can be 4.85mm, 4.9mm, 4.95mm etc..Or It says, the distance range of incidence surface 222 and shady face 224 is it is to be understood that the height for turning optical element 22 is 4.8-5.0mm.More than The incidence surface 222 of distance range is formed by that turn 22 volume of optical element moderate with shady face 224, can preferably suit and be taken the photograph into first As in head mould group 20, forming the first camera module 20, CCD camera assembly 100 and the electronic device of more compact property and miniaturization 1000, meet the more demands of consumer.
