Patent number: 11889608Abstract: A track light wireless smart control device includes a track light adaptor including a power live-in pin, a first power live-out pin and a neutral pin, a plug-in stem, a cover, an outer case, a phase-cut dimmer module and a wireless communication module. When mounted to the lighting track, the power live-in pin is connected to the power input loop in the rail, the power live-out pin is connected to the #1 live-out conductor in the rail, and the neutral pin is connected to the neutral conductor in the rail. The wireless communication module receives the command message sent by the remote control device. The phase-cut dimmer module regulates the current to the output conductor loop according to the wireless command message, so as to enable the phase-cut dimmable track lights connected to the #1 live-out conductor to power on, power off, dimming up or dimming down.Type: GrantFiled: December 11, 2022Date of Patent: January 30, 2024Assignee: WESTPORT INTERNATIONAL CO., LTD.Inventors: Ting-Mao Lin, Dong-Jung Suen

Patent number: 9970603Abstract: The present disclosure provides an illumination device. The illumination device includes a cap structure. The cap structure is partially coated with a reflective material operable to reflect light. The illumination device includes one or more lighting-emitting devices disposed within the cap structure. The light-emitting devices may be light-emitting diode (LED) chips. The illumination device also includes a thermal dissipation structure. The thermal dissipation structure is coupled to the cap structure in a first direction. The thermal dissipation structure and the cap structure have a coupling interface. The coupling interface extends in a second direction substantially perpendicular to the first direction. The thermal dissipation structure has a portion that intersects the coupling interface at an angle. The angle is in a range from about 60 degrees to about 90 degrees according to some embodiments.Type: GrantFiled: March 7, 2014Date of Patent: May 15, 2018Assignee: Epistar CorporationInventors: Chih-Hsuan Sun, Wei-Yu Yeh, Hsueh-Hung Fu, Dong Jung Suen

Patent number: 8801228Abstract: The present disclosure provides a lighting instrument. The lighting instrument includes a recessed light fixture, for example a troffer light or a batten light. The light fixture includes a plurality of light-emitting diode (LED) devices located on a board. The light fixture also includes a diffuser cap located on the board and housing the LED devices therein. The diffuser cap includes a plurality of coating regions. Each coating region is coated by a film containing white particles. The white particles can reflect and diffuse light emitted by the LED devices. The film in each coating region has a different white particle concentration level than other coating regions.Type: GrantFiled: March 15, 2012Date of Patent: August 12, 2014Assignee: TSMC Solid State Lighting Ltd.Inventors: Dong Jung Suen, Chih-Hsun Sun, Wei-Yu Yeh, Hsueh-Hung Fu
