AI Technical Summary
Technical Problem
Existing flash unit structures are complex, bulky, costly, and slow when switching between normal flash, wide-angle mode, and telephoto mode.
Method used
The lens features a convex incident surface on its incident surface and a diffused Fresnel pattern on its exit surface. Light emitted from the light source is focused by the convex incident surface and then emitted through the diffused Fresnel pattern. Combined with the prominent diffused Fresnel pattern around the convex incident surface, it enables telephoto and wide-angle fill light.
Benefits of technology
It achieves miniaturization of the flash structure, reduces costs, and improves mode switching speed, especially the switching speed between normal flash, wide-angle mode, and telephoto mode.

Abstract
This invention provides a flash unit structure. The flash unit structure includes a light source and a lens. The light source emits light, which is configured to enter the incident surface of the lens and exit through the exit surface of the lens. The incident surface of the lens has an incident convex surface, and the exit surface has a diffused Fresnel pattern. The periphery of the diffused Fresnel pattern at least partially protrudes from the periphery of the incident convex surface. This flash unit structure is simple in structure, small in size, low in cost, and achieves fast switching between normal flashing, wide-angle mode, and telephoto mode.
