Patent number: 10907774Abstract: [Object] Collection efficiency of a reflector that reflects a converted beam, which is converted from a pump beam by a phosphor, and projects the resultant as a projection beam is increased. [Solution] An optical member (4) of a light source unit (1) deflects a pump beam (PB) so that a first angle of incidence (?1) of a pump beam (PBX) relative to a surface of a phosphor (3) is larger than a second angle of incidence (?2) of the pump beam (PB), which is incident on the optical member (4), relative to the surface of the phosphor (3).Type: GrantFiled: November 19, 2019Date of Patent: February 2, 2021Assignee: Sharp Kabushiki KaishaInventors: Karl Peter Welna, Mattia Signoretto, Valerie Berryman-Bousquet

Patent number: 10840223Abstract: Emissive display devices having LED sources with super-lambertian radiation patterns. An exemplary emission source may have a half-emission-cone-angle of less than 40°. A system, such as an augmented reality display system, employing such an emissive display device may display a reduction in power of up to three times relative to LED sources with a lambertian radiation pattern. In some systems, such as augmented reality display systems, the optical path down stream of such an emissive display device may be simplified and/or dimensionally scaled, and/or manufactured to lower tolerances. For example, a discrete collimating lens may be eliminated from the optical path of such an emissive display device.Type: GrantFiled: March 23, 2017Date of Patent: November 17, 2020Assignee: Intel CorporationInventors: Khaled Ahmed, Kunjal Parikh

Patent number: 10824065Abstract: This light source apparatus includes a wheel, a motor, a rotation member, and a contact member. The wheel includes a light emitter that is excited by excitation light and emits visible light, and a base that includes a first surface and a second surface opposite thereto, supports the light emitter on either one of the first and second surfaces, and has a first linear expansion coefficient. The motor generates rotational force for rotating the base. The rotation member is connected to the first surface of the base, rotates integrally with the base due to the rotational force of the motor, and has a second linear expansion coefficient different from the first linear expansion coefficient. The contact member is connected to the second surface of the base and has a third linear expansion coefficient whose magnitude relationship to the first linear expansion coefficient is equal to a magnitude relationship of the second linear expansion coefficient to the first linear expansion coefficient.Type: GrantFiled: September 11, 2015Date of Patent: November 3, 2020Assignee: SONY CORPORATIONInventor: Takashi Takamatsu
