Illustratively, the light transmittance of the first light guiding body 21 is 80%, 85%, 90%, 95%, or 100%, and so on.

In order to achieve both the appearance effect and the light guiding effect of the second light guiding body 22, in an embodiment, please refer to fig. 2 to 4, the light transmittance of the second light guiding body 22 is between 20% and 50%. Illustratively, the light transmittance of the second light guiding body 22 is 20%, 25%, 30%, 40%, 45%, or 50%, and so on.

The material of the base materials of the first light guide 21 and the second light guide 22 is not limited, and in an exemplary embodiment, the base material of the first light guide 21 is plastic, and the base material of the second light guide 22 is silicon. The luminousness of silica gel is usually between 20% -30%, and the luminousness of plastics is usually more than or equal to 90%, and the luminousness of silica gel is less than the luminousness of plastics, and so, leaded light effect and outward appearance effect can be compromise to second light guide body 22, and excessive loss light filling light can be avoided to first light guide body 21 to further guarantee the light filling effect.

The specific type of plastic is not limited, and for example, in an embodiment, the first light guide 21 is made of a polycarbonate substrate or a polymethyl methacrylate substrate. Polycarbonate (PC) and Polymethyl methacrylate (PMMA) are transparent plastics, both of which have high light transmittance and good optical properties. In some embodiments, light diffusion powder may be further added to the first light guide 21. The light diffusion powder refers to a material that increases light scattering and transmission functions, and is generally in the form of microbeads or spheres in microscopic form. The light diffusion powder is added into the polycarbonate substrate or the polymethyl methacrylate substrate to further improve the uniformity of light supplement light distribution.

That is, the first light guiding body 21 and the second light guiding body 22 are formed of different base materials, and the light guiding member 20 can be manufactured by a two-color injection molding process. For example, the first light guide 21 is plastic, the second light guide 22 is silicone, and the light guide 20 is formed by two-color injection molding.

In an embodiment, referring to fig. 1 and fig. 2, the camera device includes a cover plate 30 disposed on an object side of the lens assembly 10, an end of the lens assembly 10 near the object side is disposed in the incident port 20a, and the cover plate 30 closes a top of the incident port 20 a. Specifically, one end of the lens assembly 10 near the object side thereof extends into the entrance port 20a from the bottom of the entrance port 20 a. The cover plate 30 closes the top of the entrance port 20a to protect the lens assembly 10 from damage. The one end that lens subassembly 10 is close to its thing side is located entrance 20a for the distance between lens group and the apron 30 is less, and on the one hand, through drawing the distance between lens group and the apron 30, the object plane of the lens that makes the inboard foreign matter of apron 30 can keep away from closest apron 30 more, thereby improves the tolerance of lens group to foreign matters such as white point broken filaments, reduces the harmful effects that white point broken filaments produced in the assembling process. On the other hand, the size of the camera device in the height direction is reduced, so that the electronic equipment can be thinner and lighter.

In one embodiment, referring to fig. 2 and 4, an inner peripheral wall surface of the incident port 20a is formed with a step surface 20a ', and the cover plate 30 is supported on the step surface 20 a'. In this manner, the distance between the cover plate 30 and the lens closest to the cover plate 30 can be further reduced.

In an embodiment, referring to fig. 1 to 4, the second light guiding element 22 and the cover plate 30 together close the light opening. On the one hand, the appearance effect of the second light guide body 22 is dark, the area of the cover plate 30 does not need to be increased to cover the second light guide body 22, the appearance consistency of the second light guide body 22 and the shell can still be guaranteed, the whole size of the cover plate 30 is small, the reliability is high, and the compatibility is facilitated. On the other hand, the cover plate 30 is not covered on the light-emitting surface 22a, and the light supplement light emitted from the light-emitting surface 22a does not pass through the cover plate 30, so that the loss of the cover plate 30 to the light supplement light can be avoided, and the cover plate 30 can be prevented from reflecting the light supplement light to the lens assembly 10, thereby further avoiding the crosstalk (flare) phenomenon.

The material of the cover plate 30 is not limited, and in an exemplary embodiment, the cover plate 30 is made of a glass substrate. The glass has high strength and scratch resistance, and thus can protect the lens assembly 10 better.

The specific structural shape of the first light guiding body 21 is not limited, and in an exemplary embodiment, referring to fig. 2 to 4, the first light guiding body 21 includes a light guiding portion 211 formed with a first through hole 211a and an incident light portion 212 disposed on an outer peripheral side surface of the light guiding portion 211, the first through hole 211a is a portion of the incident port 20a, the incident light portion 212 has an incident surface 212a for light supplementary light to enter, the incident surface 212a extends outward from the outer peripheral side surface of the light guiding portion 211 along a radial direction of the lens assembly 10, and the incident surface 212a connects a top surface of the incident light portion 212 and a bottom surface of the incident light portion 212. Specifically, the first through hole 211a penetrates the top and bottom surfaces of the light guide part 211.

The supplementary light ray enters the light guide portion 211 approximately along the circumferential direction of the lens assembly 10, so that the supplementary light ray can be prevented from directly entering the light guide portion 211 along the radial direction of the lens assembly 10 or directly emitting to the light emitting surface 22a, and the light emitting surface 22a is prevented from having too high brightness at the position of the light incident surface 212a, and the degree of explosion of the lamp is prevented from being reduced. The light guide part 211 and the second light guide body 22 can disperse the supplementary light, so as to prevent the supplementary light from being emitted in a concentrated manner, so that the uniformity of the supplementary light emitted from the light emitting surface 22a is better, the problem of uneven brightness of the light emitting surface 22a is avoided, and the appearance uniformity of the light emitting surface 22a and the uniformity of the supplementary light for the shooting area are improved.

The uniformity of the appearance of the light-emitting surface 22a refers to the brightness uniformity of the light-emitting surface 22a after the light guide 20 is illuminated.

In an embodiment, referring to fig. 2 to 4, the light guiding portion 211 includes a light guiding post 2111 formed with a first through hole 211a and an annular light guiding ring 2112 surrounding the light guiding post 2111, and the light entering portion 212 is disposed on the side surface of the outer periphery of the annular light guiding ring 2112. After the light supplementing light enters the annular light guide ring 2112 from the light inlet portion 212, the annular light guide ring 2112 is used for further dispersing the light supplementing light, and the light supplementing light uniformly distributed in the annular light guide ring 2112 enters the light guide column 2111, so that the uniformity of the light supplementing light emitted from the light emitting surface 22a is better, the problem of uneven brightness of the light emitting surface 22a is further avoided, and the appearance uniformity of the light emitting surface 22a and the uniformity of the light supplementing light to a shooting area are further improved. Specifically, the top surface of the light guide post 2111 is higher than the top surface of the annular light guide ring 2112 in the height direction of the light guide member 20. The first through hole 211a penetrates the top and bottom surfaces of the light guide 2111.

In one embodiment, referring to fig. 2 and 4, the second light guide 22 is stacked on top of the light guide post 2111, the second light guide 22 is formed with a second through hole 22b communicated with the first through hole 211a, and the second through hole 22b is a part of the incident port 20a; that is, the imaging light enters the lens assembly 10 sequentially through the second through hole 22b and the first through hole 211 a. The outer contour of the projection of the second light guide 22 coincides with the outer contour of the projection of the light guide 2111, with a plane perpendicular to the optical axis of the lens assembly 10 being a projection plane. Specifically, the second through hole 22b penetrates the top surface and the bottom surface of the second light guide 22. Thus, the fill light emitted from the light guide post 2111 is incident on the second light guide 22.

The specific structural shapes of the light guide post 2111 and the second light guide 22 are not limited, and in an embodiment, referring to fig. 3, a plane perpendicular to the optical axis of the lens assembly 10 is taken as a projection plane, a projection outline of the light guide post 2111 is circular, and a projection outline of the second light guide 22 is circular, that is, the light guide post 2111 and the second light guide 22 are both substantially cylindrical.

In an embodiment, referring to fig. 2, fig. 3 and fig. 5, a portion of the annular light guiding ring 2112 expands outward along the circumferential direction to form the light incident portion 212, and an end surface of the end of the light incident portion 212 is a light incident surface 212a. Thus, the area of the light incident surface 212a is larger, so that the fill-in light enters the light incident portion 212 from the light incident surface 212a.

In order to reduce the loss of the fill-in light on the light incident portion 212, in an embodiment, referring to fig. 2, 3 and 5, the peripheral side surface 212b of the light incident portion is a convex arc surface, and the peripheral side surface 212b of the light incident portion and the peripheral side surface of the annular light guide ring 2112 are in smooth transition. Specifically, the outer edge of the outer peripheral side surface 212b of the light incident portion is connected to the top surface of the light incident portion 212, the bottom surface of the light incident portion 212, and the light incident surface 212a, respectively. Thus, a sharp corner formed on the incident portion 212 is avoided, and loss in the light supplement light propagation process is reduced.

In an exemplary embodiment, referring to fig. 3 and 5, a plane perpendicular to the optical axis of the lens assembly 10 is taken as a projection plane, the light incident portion 212 is substantially shaped like a fish fin, and the contour line of the outer peripheral side surface 212b of the light incident portion is an outward convex arc line.

In one embodiment, referring to fig. 2 and 4, the annular light guide ring 2112 surrounds the bottom of the light guide post 2111. Thus, in the height direction of the light guide 20, the distance between the light incident surface 212a and the light emitting surface 22a is further long, thereby further reducing the degree of lamp explosion.

In an embodiment, referring to fig. 3, a plane perpendicular to the optical axis of the lens assembly 10 is taken as a projection plane, a circle of a projection outer contour of the annular light guide ring 2112 is substantially inscribed with a circle of a projection contour of the outer peripheral side surface 212b of the light incident portion, and a tangent point between the two is located at an end of the light incident portion 212 far away from the light incident surface 212a. Thus, the light entering portion 212 can further guide the fill light into the annular light guide ring 2112.

For example, in an embodiment, referring to fig. 3, the number of the light-entering portions 212 is multiple, so that more supplementary light rays can enter the light-guiding portion 211, thereby improving the overall supplementary light brightness. The plurality of light incident portions 212 are uniformly distributed at intervals along the circumferential direction of the lens assembly 10. Therefore, the light supplement uniformity is improved. Illustratively, the number of the light incident portions 212 is two, and the two light incident portions 212 are uniformly distributed along the circumferential direction of the lens assembly 10. In another embodiment, the number of the light incident portion 212 is one.

In the embodiments of the present application, the plurality means two or more. For example, the number of the light incident portions 212 is 2 to 20. Therefore, the uniformity and the intensity of the light supplement can be considered.

In one embodiment, referring to fig. 3, the camera device includes a side light-emitting lamp 40 located at an outer peripheral side of the first light guide 21, the side light-emitting lamp 40 has a light-emitting surface 40a for emitting light for supplementing light, the light-emitting surface 40a connects a bottom surface of the side light-emitting lamp 40 and a top surface of the side light-emitting lamp 40, and the light-emitting surface 40a faces the light-incident surface 212a.
