Patent number: 9104089Abstract: An electronic device includes a lens assembly, a lens focusing rod, a power switch and a lens protective cover. When the lens protective cover is located in the first position, the lens assembly is shielded by the lens protective cover, the power switch is turned off, and the lens protective cover is separated from the lens focusing rod. When the lens protective cover is located in the second position, the power switch is turned on, and the lens protective cover is contacted with the lens focusing rod. When the lens protective cover is moved between the second position and the third position, the power switch is turned on, and the lens assembly is driven by the lens protective cover through the lens focusing rod for focusing operation.Type: GrantFiled: August 5, 2013Date of Patent: August 11, 2015Assignees: SINTAI OPTICAL (SHENZHEN) CO., LTD., ASIA OPTICAL INTERNATIONAL LTD.Inventors: Chen-Ren Yu, Yi-Chung Hung, Wei-Ming Tseng

Publication number: 20120182532Abstract: An automatic focus system of a projector includes a projecting module, an image catching module, a memory, a micro processor, and a focusing module. The projecting module has an image light source to provide image light, and a projecting lens to project the image light on a screen. The image catching module senses an image on the screen. The microprocessor calculates the sensed image to have a definition value of the image and save the definition value in the memory. The focusing module may move the projecting lens is moved along an optical axis under a control of microprocessor. The microprocessor compares the definition values to control the focusing module to move the cam to a position where the projector may project a clear image on the screen.Type: ApplicationFiled: June 23, 2011Publication date: July 19, 2012Applicant: AISA OPTICALCO., INCInventors: Sen-Yung Liu, Chien-chih Hsiung, Chen-Ren Yu, Kuo-Liang Wen, Yi-Chung Hung, Chiao-Sen Hsu, Chao-Yang Ke, Keng-Hui Lin, Fu-Shan Wu

Patent number: 8011791Abstract: A light-filtering module includes a light-source module, a dichroic mirror and a first image unit. The light-source module outputs a light beam. The dichroic mirror divides the light beam into a first colored light and a dual colored light. The first image unit provides the first colored light with image information. The light-filtering module includes a light-filtering unit and a driving unit. The light-filtering unit is located between the dichroic mirror and the first image unit is located at a light path of the first colored light. The driving unit includes a coupling element coupled to the light-filtering unit and a driving element utilized to drive the coupling element. The driving element drives the light-filtering unit, switching between a first status and a second status by the coupling element. A wide-wavelength spectrum and a narrow-wavelength spectrum are provided when the light-filtering unit is in the first and second statuses, respectively.Type: GrantFiled: October 1, 2008Date of Patent: September 6, 2011Assignee: Asia Optical Co., Inc.Inventors: Chien-Chih Hsiung, Tzu-Lung Wu, Keng-Hui Lin, Wen-Lang Hung, Wei-Hsiang Peng, Chao-Yang Ke, Yi-Chung Hung

Patent number: 7771084Abstract: A light emitting system is disclosed, including a light generator, a complex lens and an activating unit. The light generator provides a light beam emitted in a first direction in parallel to an optic axis. The complex lens, disposed on a path of the light beam, includes a plurality of micro structures for refracting the light beam. The activating unit includes an activating member coupled to the complex lens. The activating member activates the complex lens with an activation frequency to reciprocally move in a second direction alternate to the first direction. By the disposition of the complex lens, the energy of the light beam is uniformly distributed. Additionally, speckle produced by the light beam is reciprocally moved within an area by the activating unit, creating a photogene reaction, to successfully eliminate existence of the speckle.Type: GrantFiled: June 26, 2008Date of Patent: August 10, 2010Assignee: Asia Optical Co., Inc.Inventors: Chien-Chin Hsiung, Keng-Hui Lin, Wen-Lang Hung, Wei-Hsiang Peng, Chao-Yang Ke, Yi-Chung Hung
