Patent number: 11914277Abstract: An illumination system for providing an illumination beam includes red, blue, and green light source modules, a first light combining element, and a light uniforming element. The red light source module includes a first red light emitting element emitting first red light and a second red light emitting element emitting second red light. A peak wavelength of the second red light is greater than a peak wavelength of the first red light. The blue light source module includes a first blue light emitting element emitting first blue light and a second blue light emitting element emitting second blue light. A peak wavelength of the second blue light is less than a peak wavelength of the first blue light. The green light source module generates green light. The first light combining element guides these lights into the light uniforming element, so that the illumination system outputs the illumination beam.Type: GrantFiled: January 18, 2022Date of Patent: February 27, 2024Assignee: Coretronic CorporationInventors: Hung-Yu Lin, Chi-Fu Liu, Chun-Hsin Lu, Chun-Li Chen

Patent number: 8450544Abstract: A method for preparing the low carbon number petrochemical products along with the high energy fuels from pyrolysis gasoline is provided. In this method, the pyrolysis gasoline is used as feedstock, and the reactive non-aromatic, unsaturated moieties, and the sulfur impurity contained in the pyrolysis gasoline are removed. Then the stabilized feedstock is used to produce C5 olefins, C6-C9 aromatic hydrocarbons as petrochemical products, and C10+ hydrocarbons as precursors of high energy fuels. Upon acid catalytic isomerization, or upon crystallization followed by acid catalytic isomerization, the C10+ hydrocarbons as precursors of high energy fuels are converted to exo-isomers as high energy fuels.Type: GrantFiled: April 9, 2007Date of Patent: May 28, 2013Assignee: CPC Corporation, TaiwanInventors: Ying-Yen Tsao, Chyuan-Neng Liao, Chi-Yu Chen, Chin-Ming Lin, Kuo-Min Wei
