Patent number: 9879848Abstract: An LED illumination apparatus includes a first lighting module, a second lighting module, a lamp cup, a heat pipe, and a plurality of heat dissipation fins. The first and second lighting modules are connected with each other and emit light in opposite directions, in addition being received by the lamp cup. The lamp cup includes two reflecting surfaces arranged in symmetrical mirror fashion. The light emitting from the first and second lighting modules are directed to respective reflecting surfaces and reflected toward a same direction by the reflecting surfaces. The heat pipe is disposed in between the first and second lighting modules. The heat dissipation fins are fitted over the heat pipe. The heat generated by lighting modules would transmit to the heat pipe and be guided to the heat dissipation fins in order to accelerate cooling.Type: GrantFiled: June 9, 2016Date of Patent: January 30, 2018Assignee: NATIONAL TAIWAN UNIVERSITYInventors: Guo-Dung Su, Chih-Hao Hsu

Patent number: 9140897Abstract: An optical system, an optical module and a method of manufacture thereof are provided. The optical module includes a top membrane and a bottom electrode. The top membrane includes a supporting layer, a first metal layer and an isolating layer with an opening. The first metal layer is disposed on lower surface of the supporting layer. The isolating layer is disposed on lower surface of the first metal layer. The bottom electrode, disposed below the top membrane, includes a second metal layer and a plurality of pillars. The pillars are disposed on upper surface of the second metal layer and below the isolating layer, wherein some of the pillars support the isolating layer. Wherein the pillars are used for preventing the top membrane from being pulled down to touch the second metal layer through the opening when a voltage is applied between the first and the second metal layers.Type: GrantFiled: May 10, 2011Date of Patent: September 22, 2015Assignee: NATIONAL TAIWAN UNIVERSITYInventors: Guo-Dung Su, Hsin-Ta Hsieh

Patent number: 9030746Abstract: The present invention discloses a fabrication method of a microlens array (MLA) and an MLA fabricated using the same. The fabrication method of an MLA comprises: providing a substrate with an interface hydrophilic modified polymer layer; using light, gas or liquid with the property of converting the polymer' hydrophilicity to create a hydrophilic zone on the interface hydrophilic modified polymer layer; coating the substrate with a liquid material to condense a plurality of liquid microlenses in the hydrophilic zone; and curing the plurality of liquid microlenses to form a plurality of microlenses. Therefore, the fabrication method of an MLA has advantages of fast speed, low cost, no etch transfer and low temperature.Type: GrantFiled: November 20, 2012Date of Patent: May 12, 2015Assignee: National Taiwan UniversityInventors: Hsiang-Chun Wei, Guo-Dung Su

Patent number: 7713453Abstract: A method for fabricating micro-lenses and a method for fabricating micro-lenses by photolithography are provided. The method includes forming a plurality of micro-cavities in a substrate, filling lens material into each of the micro-cavities, and heating the lens material, thereby reflowing the lens material so as to form a plurality of micro-lenses in the substrate. The micro-cavities define a boundary of each of the micro-lenses formed by reflowing the lens material, thereby preventing adjacent micro-lenses from fusing together by reflowing when overheated. The process uses negative photoresist and positive photoresist as micro-cavities and lens material respectively, thereby streamlining the fabrication method and its steps.Type: GrantFiled: January 20, 2009Date of Patent: May 11, 2010Assignee: National Taiwan UniversityInventors: Guo-Dung Su, Hsin-Ta Hsieh
