Patent number: 8807794Abstract: An illumination device includes a base, a flexible circuit board disposed on the base, and a plurality of illumination units. The flexible circuit board has a plurality of first branches and at least one second branch which are connected together. Each of the first branches has a radius of curvature, and the radii of curvature of the first branches are different from or identical to one another, so that the first branches are assembled to form a curved surface. The second branch extends from one of the first branches. After the first branches are assembled, the second branch is overlapped with another first branch. The illumination units are packaged onto the first branches of the flexible circuit board. Here, the illumination units located on one of the first branches is electrically connected to the illumination units located on another of the first branches through the second branch.Type: GrantFiled: April 5, 2012Date of Patent: August 19, 2014Assignee: Industrial Technology Research InstituteInventors: Tien-Fu Huang, Sheng-Chiang Peng, Shih-Hao Hua, Chi-Hua Yu

Patent number: 8664675Abstract: A multichip light-emitting diode (LED) includes a reflective cup, a plurality of light-emitting chips and a package. The light-emitting chips are disposed in the reflective cup and emit light when driven. The package is disposed in the reflective cup and covers the light-emitting chips. The package further has a plurality of lenses corresponding to the light-emitting chips one by one. The lenses refract light emitted by the corresponding light-emitting chips, respectively. An extrinsic light efficiency of the multichip is increased through the design of the multichip LED.Type: GrantFiled: March 27, 2009Date of Patent: March 4, 2014Assignee: Industrial Technology Research InstituteInventors: Tien-Fu Huang, Shih-Hao Hua

Patent number: 8178892Abstract: A light-emitting diode (LED) chip having a micro-lens structure includes a light-emitting structure and a light guide lens. The light-emitting structure emits a light from a light-emitting surface upon being applied with a current, and the light guide lens is stacked on the light-emitting surface and used for emitting the light from a light guide surface of the light guide lens. The light guide surface has an annular ridge portion and a scatter region, such that the lights close to the central optical axis of the light-emitting surface (the region having the maximum light-emitting intensity) are deflected in a direction away from the central optical axis, and the lights far away from the central optical axis are deflected towards the central optical axis, so as to obtain a light with a uniform overall optical intensity.Type: GrantFiled: July 16, 2007Date of Patent: May 15, 2012Assignee: Industrial Technology Research InstituteInventors: Tien-Fu Huang, Shih-Hao Hua, Kuo-Chang Hu, Che-wei Su

Patent number: 8016460Abstract: A converging element for an LED is described, which is used for converging light rays emitted from a light-emitting chip to enable the light rays to form approximately parallel light rays after passing through the converging element. The converging element for LED includes a cylinder and a first lens. The cylinder is disposed on the light-emitting chip. The first lens is disposed on the other end of the cylinder opposite to the light-emitting chip. The first lens has a first plane and a first curved surface opposite to each other. The first plane of the first lens is attached to the cylinder.Type: GrantFiled: February 20, 2009Date of Patent: September 13, 2011Assignee: Industrial Technology Research InstituteInventors: Tien-Fu Huang, Shih-Hao Hua, Chen-Dao Shaio
