Abstract

A SMD type Fresnel LED micro flash light structure, which is adapted to a camera of a mobile phone, includes a housing, an array-type light source and a micro-cylindrical Fresnel lens. The housing has a bottom wall and a plurality of side walls, and defines a longitudinal direction and a width direction. The array-type light source is disposed on the bottom wall along the longitudinal direction. The micro-cylindrical Fresnel lens covers the housing, and includes a cylindrical plano-convex lens, and two teeth-shaped lens sections respectively arranged at two sides of the cylindrical plano-convex lens. Each teeth-shaped lens section has a plurality of bar teeth-shaped lenses. The cylindrical plano-convex lens and the bar teeth-shaped lenses are parallel to each other along the width direction. A central axis of the cylindrical plano-convex lens is corresponding to a central position of the array-type light source.
