Publication number: 20140218968Abstract: A planar lighting device includes a light guide plate and a side-emitting lighting module. The light guide plate includes a light emission surface, a back light surface, and at least one side surface. The back light surface is opposite to the light emission surface, and the side surface extends between the light emission surface and the back light surface. The side-emitting lighting module is embedded into the light guide plate, such that the side-emitting lighting module emits light toward the side surface of the light guide plate. The light is then guided by the light guide plate and emerges from the light emission surface of the light guide plate.Type: ApplicationFiled: July 31, 2013Publication date: August 7, 2014Applicant: NATIONAL CENTRAL UNIVERSITYInventors: Ching-Cherng SUN, Chi-Shou WU

Publication number: 20140218969Abstract: The present invention relates to an illumination device where a number of light sources are arranged on a heat sink and adapted to emit light in substantially the same direction. The heat sink comprises a first cooling plate and a second cooling plate and a first part of the light sources are arrange on the first cooling plate and a second part of the light sources are arranged on the second cooling plate. The first and second cooling plates are further separated by a distance and a flow channel is defined there between. The flow channel allows cooling fluid to flow between the first cooling plate and the second cooling plate whereby the light sources can be cooled by the cooling fluid. The heat sink comprises further a number of light passages allowing light to propagate from the second cooling plate, towards the first cooling plate and through the first cooling plate. The present invention relates also to a method of cooling light sources emitting light in substantially the same direction.Type: ApplicationFiled: June 8, 2012Publication date: August 7, 2014Applicant: Martin Professional A/SInventors: Jens Søren Kjaer, Dennis Jørgensen

Publication number: 20140218970Abstract: A light guide plate used for an LED backlight source. The LED backlight source comprises a plurality of LED lamps. The light guide plate comprises a light guide plate body (24). The light guide plate body (24) is provided thereon with a plurality of dots (242), and there is a light guide region in the light guide plate body (24). In the light guide region, the diameters of the dots in the same dot row progressively increase from the middle to either side, and diameters of the dots in the same dot column progressively increase in the direction away from the LED lamps.Type: ApplicationFiled: March 15, 2013Publication date: August 7, 2014Applicant: BEIJING BOE OPTOELECTRONICS TECHNOLOGY CO, LTD.Inventors: Yanping Wu, Fei Shang, Daekeun Yoon, Guanghui Xiao

Publication number: 20140218974Abstract: A USB power adapter for AC and DC power has a circuit board, a base and a top cover. The base and the top cover receive the circuit board therein. The circuit board has an AC conversion module, a DC conversion module, and a USB connection port. The base has a cigarette lighter electrically connected to the DC conversion module. The top cover has a pair of blades electrically connected to the AC conversion module. The AC power inputted through the pair of blades is converted by the AC conversion and the DC conversion module into the power outputted through the USB connection port. Accordingly, it is unnecessary to prepare a dedicated AC or DC charger depending upon the type of power source or to prepare a charger requiring many replaceable plugs. The inconvenience caused by carrying and operating those chargers or plugs can be resolved.Type: ApplicationFiled: February 1, 2013Publication date: August 7, 2014Applicant: QUIETEK CORPORATIONInventor: Kao-Chun Chang
