[0035] In order to further explain the technical solution of the present invention, it will be described in detail below with reference to the accompanying drawings.
[0036] figure 1 with figure 2 The lens shown is a wide-angle optical lens with uniform near-field illumination of the present invention, which is made of a transparent material with a refractive index of 1.45-1.6 through an injection molding process. The material is not limited to polycarbonate (PC), polymethyl methacrylate (PMMA).
[0037] Such as figure 2 As shown, in this example, the wide-angle lens is rotationally symmetric about the Z axis. The optical lens includes an inner concave surface 2, an outer convex surface 3, a bottom surface 4, a positioning bracket 5 and a microstructure 7. The light emitting diode 1 is placed directly below the central axis of the bottom of the lens, and the light emitting surface of the light source is flush with the bottom surface. The inner concave surface 2 is the incident...
