Patent number: 10416545Abstract: A laser projector includes a light-mixing module and a light-splitting module. The light-mixing module provides a laser beam which includes first polarized light and second polarized light. The light-splitting module includes a dichroic mirror, a half-wave plate, a phosphor wheel module, and a light-guiding rod. The dichroic mirror allows the first polarized light to pass and reflects the second polarized light. The half-wave plate receives the first polarized light which passes the dichroic mirror and converts the first polarized light into third polarized light. The phosphor wheel module receives the second polarized light reflected by the dichroic mirror, and provides a stimulated light which passes the dichroic mirror. The light-guiding rod receives the stimulated light and the third polarized light, thereby providing an illumination beam.Type: GrantFiled: January 11, 2018Date of Patent: September 17, 2019Inventors: Kai-Jing Wang, Huan-Yu Lin, Chun-Hao Hu

Patent number: 9638991Abstract: A projection device includes a light source module and a light splitter module. The light source module includes a first light source, a second light source, a reflection module and a polarizing module. The first light source emits a first light beam with a first polarization direction. The second light source emits a second light beam with a second polarization direction. The reflection module is disposed corresponding to the first light source along the first axis, and is used to reflect the first light beam to a second axis. The polarization module is disposed corresponding to the second light source along the first axis and corresponding to the reflection module along the second axis. The polarization module is used to direct the first light beam to pass through the polarization module along the second axis and reflect the second light beam to the second axis through the light splitter module.Type: GrantFiled: October 22, 2015Date of Patent: May 2, 2017Assignees: Qisda Optronics (Suzhou) Co., Ltd., Qisda CorporationInventor: Kai-Jing Wang

Patent number: 9261638Abstract: A flexible light guide film having a light-adjusting structure in the form of a lenticular-like microstructure on the bottom side of the light guide film. The light guide film has a substrate layer supporting a layer light-adjusting structure, which is in the form of an array of longitudinal lenticular lenses laterally arranged in parallel. A prismatic-like microstructure may be provided on the top light emitting side of the light guide film. The light guide film is fabricated by a process involving coating/embossing of a roll of sheet material, in a roll-to-roll continuous process. Advantages includes significantly reducing the thickness of the light guide film, and the roll-to-roll fabrication process provides for more precise replication of the microstructures on the master mold or drum onto the surface of the light guide film, which in turn reduces the failure rate and manufacturing cost.Type: GrantFiled: June 7, 2011Date of Patent: February 16, 2016Assignee: UBRIGHT OPTRONICS CorporationInventors: Kong-Hua Wang, Kai-Jing Wang, Fang-Chun Yeh, Ching-An Yang, Yi-Chun Huang

Patent number: 9075178Abstract: An optical substrate having a structured light output surface that comprises rows of laterally arranged snaking, wavy or meandering longitudinal prism structures. The prism structures at the light output surface may be viewed as comprising rows of laterally meandering longitudinal prisms and/or sections of curved segments coupled end-to-end to form the overall meandering longitudinal prism structures. The laterally meandering rows of longitudinal prism structures are arranged in parallel laterally (side-by-side), defining parallel peaks and valleys (a facet is defined between each adjacent peak and valley). In one embodiment, the lateral waviness is regular with a constant or variable wavelength and/or wave amplitude (or extent of lateral deformation). The lateral waviness may generally follow a sinusoidal profile, or other curved profile.Type: GrantFiled: February 3, 2014Date of Patent: July 7, 2015Assignee: UBright Optronics CorporationInventors: Kong-Hua Wang, Kai-Jing Wang, Fang-Chun Yeh

Publication number: 20150185598Abstract: A laser projection apparatus includes a light mixing module and a light splitting module. The light mixing module includes a first laser set, a quarter-wave plate, a first dichroic mirror and a reflector. The first laser set includes first and second laser sources for emitting first and second light with the same polarization, respectively. The first dichroic mirror reflects the first light along a first path and reflects the second light to pass through the quarter-wave plate. The reflector reflects the second light back to the quarter-wave plate, then the second light passes through the quarter-wave plate and the first dichroic mirror and then is mixed with the first light along the first path thereby forming a laser beam. The light splitting module receives the laser beam and splits the laser beam into a plurality of color lights.Type: ApplicationFiled: December 25, 2014Publication date: July 2, 2015Inventor: KAI-JING WANG

Patent number: 8638408Abstract: An optical substrate having a structured prismatic surface and an opposing structured lenticular surface. The structured lenticular surface includes shallow-curved lens structures. Adjacent shallow-curved lens structure may be continuous or contiguous, or separated by a constant or variable spacing. The lens structure may have a longitudinal structure with a uniform or varying cross section. The lenticular lenses may have a laterally meandering structure. Sections of adjacent straight or meandering lenticular lenses may intersect or partially or completely overlap each other. The lenticular lenses may be in the form of discontinuous lenticular segments. The lenticular segments may have regular, symmetrical shapes, or irregular, asymmetrical shapes, which may be intersecting or overlapping, and may be textured. The lens structure may be provided with isolated ripples, in the form of a single knot, or a series of knots.Type: GrantFiled: March 28, 2011Date of Patent: January 28, 2014Assignee: Ubright Optronics CorporationInventors: Kong-Hua Wang, Kai-Jing Wang, Fang-Chun Yeh, Ching-An Yang, Yi-Chun Huang
