With the advancement of technology, there are more and more rear elements such as a rear camera of a terminal device in the related art, for example, a housing in the related art is generally provided with: matrix camera, flash lamp, TOF (time of flight range) subassembly, anti-flicker sensor etc.. Each camera comprises a corresponding photosensitive element, the number of the cameras is increased, and the number of the photosensitive elements is also gradually increased.

The positions reserved for the rear camera assembly and the flash lamp assembly by the terminal equipment are limited, the number of the cameras is increased, and the distances between the adjacent rear cameras and between the rear cameras and the flash lamp assembly are reduced. Under the condition, when the flash lamp component works, the emitted light inevitably interferes with the photosensitive element of the camera, so that the normal work of the photosensitive element is influenced. In addition, in the related art, the casing portion in which the image pickup assembly and the flash assembly are disposed is generally made of transparent glass, and since the transparent glass is more transparent, light from the flash assembly is more likely to interfere with the photosensitive element of the camera.

For solving above-mentioned technical problem, this embodiment of the present disclosure provides an optical module, is applied to terminal equipment, and optical module includes camera assembly and light filling subassembly, and optical module still includes: the isolation structure is arranged between the light supplementing assembly and the camera shooting assembly and corresponds to the light supplementing assembly; the isolation structure is used for shielding light rays of the light supplementing assembly between the light supplementing assembly and the camera shooting assembly. This light that the light filling subassembly sent can be sheltered from to isolation structure through setting up to this disclosure prevents that the photosignal of light filling subassembly from disturbing the photosensitive element of the subassembly of making a video recording, guarantees to make a video recording that the photosensitive element of subassembly normally accomplishes light collection work.

In an exemplary embodiment, the optical module of this embodiment is applied to a terminal device, the optical module includes a camera module and a light supplement module, and a positional relationship between the light supplement module 20 and the camera module 30 on the housing 10 of the terminal device can be shown in fig. 1. The terminal device may be, for example, an electronic device such as a mobile phone, a notebook computer, a tablet computer, and a smart watch. In this embodiment, the optical module further includes: and the isolation structure 40 is arranged between the light supplement assembly 20 and the camera assembly 30, and the isolation structure 40 corresponds to the light supplement assembly 20.

As shown in fig. 1, in the present embodiment, the isolation structure 40 corresponds to the light supplement component 20, and may be, for example: the size of the isolation structure 40 corresponds to the size of the light supplement assembly 20, for example, in the length direction of the terminal device, the length of the isolation structure 40 is the same as the length of the light supplement assembly 20.
