Optical lens, method for manufacturing the optical lens and light source module incorporating the optical lens |
摘要 |
A method for manufacturing an optical lens includes providing an uncured light diffusion body, the light diffusion body comprising a first optical surface located at a bottom thereof, and a second optical surface located at a top thereof and arranged oppositely to the first optical surface, the light diffusion body defining a receiving cavity recessed from a central portion of the second optical surface toward the first optical surface; introducing a light transmissive material doped with diffusion particles into the receiving cavity to a desired thickness; and solidifying the light transmissive material and the light diffusion body. An optical lens manufactured by the method and a light source module incorporating the optical lens are also provided. |

1. A method for manufacturing an optical lens configured to diffuse light emitted from a light emitting diode (LED) light source, the method comprising:
providing a uncured light diffusion body, the light diffusion body comprising a first optical surface located at a bottom thereof, and a second optical surface located at a top thereof and arranged oppositely to the first optical surface, the light diffusion body defining a receiving cavity recessed from a central portion of the second optical surface toward the first optical surface; introducing a light transmissive material doped with diffusion particles into the receiving cavity to a desired thickness; and solidifying the light transmissive material and the light diffusion body. |
