Patent number: 11994695Abstract: The present disclosure provides a fly-eye lens module, a lighting device, and a DLP optical engine. The fly-eye lens module includes a first plastic fly-eye lens, a second plastic fly-eye lens, and a glass triangular prism structure. The first plastic fly-eye lens is provided on a surface thereof with a first circular region, and the second plastic fly-eye lens is provided on a surface thereof with a second circular region. The first and the second circular regions are both configured as a fly-eye structure having a concave-convex structure, and are respectively fixed to two sides of the cuboid glass structure by a bonding agent. The second and the first plastic fly-eye lenses are disposed such that the light spot emitted from the point light source is incident to the fly-eye lens module via the first plastic fly-eye lens, and is emitted from the second plastic fly-eye lens.Type: GrantFiled: May 4, 2023Date of Patent: May 28, 2024Assignee: IVIEW DISPLAYS (SHENZHEN) COMPANY LTD.Inventors: Yexin Xia, Liang Mei, Mingnei Ding, Steve Yeung, Zhiqiang Gao
