Patent number: 12001129Abstract: A light mixing module is provided. The light mixing module includes a first laser array, a second laser array, and one or more laser polarized fold mirrors. The first laser array is configured for emitting a plurality of polarized light beams having a first polarization state. The second array is configured for emitting a plurality of polarized light beams having the first polarization state. The second laser array is disposed opposite to the first laser array. The one or more laser polarized fold mirrors are disposed between the first laser array and the second laser array. The one or more laser polarized fold mirrors reflect the polarized light beams emitted by the first laser array and the polarized light beams emitted by the second laser array. Each one of the one or more laser polarized fold mirrors is configured to direct light beams from at least two different directions.Type: GrantFiled: November 22, 2022Date of Patent: June 4, 2024Assignee: BenQ CorporationInventors: Kai-Jiun Wang, Hung-Chi Tsai, Shuang-Xi Lin
