As shown in fig. 3, taking the at least two lenses 21 including three lenses as an example, the fixing bracket 22 may be a plate-shaped bracket, the plate-shaped bracket may include three right-angle sides and three circular-arc sides, and the three circular-arc sides may be respectively matched with outer edges of the three lenses, so that the three lenses 21 may be fixed on the plate-shaped bracket.

In this embodiment, the driving assembly 3 is connected to each of the lenses 21 through the fixing bracket 22, so that the assembly and disassembly are convenient, and the structure is simple.

Alternatively, as shown in fig. 1 and 2, the driving assembly 3 has a driving shaft 31, and the driving shaft 31 is connected to the middle portion of the fixing bracket 22.

Wherein, the driving shaft 31 can drive the lens 21 to rotate via the fixing bracket 22. The driving shaft 31 may be driven by a motor 32, and one end of the driving shaft 31 may be connected to the fixing bracket 22 and the other end may be connected to the motor 32.

In this embodiment, the electronic device is provided with three lenses with different refractive indexes, so that the functions of short-distance flashing, long-distance flashing and ultra-long-distance flashlight can be realized, and the flexibility of the flashlight is further improved.

Optionally, each of the lenses 21 is a fresnel lens.

Wherein, when viewed from the cross section of the Fresnel lens, the surface of the Fresnel lens can be a series of sawtooth-shaped grooves, and the center part of the Fresnel lens is an elliptic arc. Each groove can have different angles with adjacent grooves, and each groove concentrates light rays at one position to form a central focus which is used as the focus of the Fresnel lens. Each groove may correspond to a separate lenslet that collimates or concentrates light. By changing the angle of the serrations of the fresnel lens, the angle of scattering of the light source 1 can be adjusted.

The distance of the light emitted by the light source 1 projected through the first lens is less than that of the light projected through the second lens, and the distance of the light emitted by the light source 1 projected through the second lens is less than that of the light projected through the third lens. Taking an electronic device as an example of a mobile phone, the first lens is taken as a currently used lens, and functions of a short-distance flash lamp and a short-distance flashlight of the mobile phone can be realized; the second lens is used as the currently used lens by rotating the lampshade 2, and can be used when a long-distance object is shot at night, so that the long-distance flashlight function is realized; the third lens is used as the currently used lens by rotating the lampshade 2, so that the functions of the ultra-long distance flash lamp and the ultra-long distance flashlight of the mobile phone can be realized.
