Publication number: 20180010768Abstract: A method for fabricating a solid-state lighting body, which differs from a conventional solid-state lighting body doping lighting powder in a filling material during a high-temperature calcining process, and mixes lighting powder with either organic powder or inorganic powder to form liquid mixture, thereby fabricating the solid-state lighting body in pour molding. The method is performed at a lower temperature without the high energy consumption and high equipment cost. The solid-state lighting body is easily molded at a low temperature without damaging the structure properties of the lighting powder and decreasing the lighting efficiency. As a result, the solid-state lighting body of the present invention has very good heat-resistant abilities and efficiently prevents lighting elements from high-temperature cracking resulted from long-term illumination, so as to increase use life and reliability.Type: ApplicationFiled: July 6, 2016Publication date: January 11, 2018Inventor: Rong-Seng CHANG

Publication number: 20160323998Abstract: The present invention proposes substrate material favoring via hole electroplating to overcome the conventional problem that the polymer-based printed circuit board is hard to conduct electricity and likely to have poor electroplating quality. The present invention adds a conductive material to a polymeric material and controls the proportions and structure thereof to form a substrate material so as to improve the affinity of the substrate material to the metal electroplated inside the via hole with the resistance of the substrate material remaining in an allowable range. Thereby is increased yield and efficiency and saved time and cost in fabricating printed circuit boards. Further, the present invention reduces the proportion of the polymeric material with the mechanical strength remaining in an allowable range so as to decrease the overall expansion rate and obtain a fire-proof effect. Therefore, the substrate material can be used to fabricate precision products.Type: ApplicationFiled: April 28, 2015Publication date: November 3, 2016Inventor: Rong-Seng CHANG

Publication number: 20130139809Abstract: A linear solar energy concentrator includes a fastening rack, a concentrating lens, and a line-shaped solar panel. The concentrating lens is fastened on the fastening rack. When sunlight irradiates on and penetrates through the concentrating lens, the light is concentrated onto a focal line parallel to a direction of the linear geometric structure of the concentrating lens. The solar panel is installed under the concentrating lens and located at the focal line, wherein when an incident angle of sunlight constantly changes, the light irradiating on and penetrating through the concentrating lens still is able to be concentrated onto a same location or onto locations slightly shifted each other along the focal line on the solar panel, so as to perform an energy conversion from solar energy to electricity at a substantially same amount of light without being affected by the incident angle of sunlight.Type: ApplicationFiled: December 1, 2011Publication date: June 6, 2013Inventors: Kung Chieh Chang, Rong Seng Chang

Publication number: 20040132005Abstract: A method of forming a biochip in which a micro-carrier having a bar code or a number code thereon is provided. A surface-modifying step is performed for modifying a surface of the micro-carrier to an aminated surface. A solid-phase peptide synthesis step is then conducted to synthesize a peptide having a specific amino acid sequence on the aminated surface of the micro-carrier or immobilizing an antibody or an antigen on the aminated surface of the micro-carrier. The micro-carrier can be applied on a biological activity analysis or an antibody-antigen interaction analysis, and the results can be read out directly from the bar code or the number code on the micro-carrier.Type: ApplicationFiled: September 10, 2003Publication date: July 8, 2004Inventors: Jing-Hsiang Hsu, Wen-Yih Chen, Rong-Seng Chang, Rong-Nan Huang, Wen-Ren Li

Patent number: 6278558Abstract: A zoom lens set with a fixed distance between lenses comprises at least one gradually changed curvature lens. The surface with a gradually changed curvature surfaces is locally limited by a suitable size pupil along an optical axis. In assembling, gradually changed curvature lenses are installed within a system so that the two lenses are retained within a fixed distance. Thereby, the or more gradually changed curvature lenses are adjusted and chosen by a local pupil to have a desired local curvature pairs or sets by relative transverse movement or rotation of the two or more lenses. Therefore, the focus of the system is changed to achieve the zooming purposed. By a simple design, the system can be completely matched with the zoom lens set with a fixed distance between the lenses so that the manufacturing cost of the system can be reduced effectively.Type: GrantFiled: September 17, 1999Date of Patent: August 21, 2001Inventor: Rong-Seng Chang
