Title:
MATRIX OPTICAL SYSTEM, LIGHT CONCENTRATING SYSTEM, AND COMPOUND EYE LENS
Document Type and Number:
WIPO Patent Application WO/2020/140764
Kind Code:
A1
Abstract:
A matrix optical system (100), a light concentrating system, and a compound eye lens (700), the matrix optical system (100) comprising: a first lens (110) and a second lens (120); the first lens (110) comprises a plurality of first lens units (111); the focal length of the plurality of first lens units (111) is different; the second lens (120) comprises a plurality of second lens units (121); the focal length of the plurality of second lens units (121) is different; the spacing of the plurality of first lens units (111) and the spacing of the plurality of second lens units (121) is different; and the first lens (110) and the second lens (120) are spaced apart and arranged in parallel. By means of setting the spacing and the focal length of the non-coaxial lens units, light rays can be made to implement a light concentration or light scattering effect after entering the matrix optical system (100), enhancing the light emission strength of the matrix optical system (100) and improving the light emission efficiency of the system.
