Title:
OPTICAL DIFFUSION SHEET AND LIGHT EMISSION MODULE
Document Type and Number:
WIPO Patent Application WO/2023/035500
Kind Code:
A1
Abstract:
The present application relates to the technical field of optical imaging, and discloses an optical diffusion sheet and a light emission module. The optical diffusion sheet of the present application comprises a base layer and a structural layer provided on the base layer; the structural layer comprises microlens groups; each microlens group comprises a plurality of interconnected microlenses; the plurality of microlenses can deflect and modulate a beam direction. The optical diffusion sheet provided by the present application can deflect a light beam irradiated thereon, and under the irradiation of a vertically incident light beam, the optical diffusion sheet can cause divergent light to emerge obliquely, so as to achieve a more flexible beam shaping effect.
