Patent number: 10816184Abstract: A tubular LED lighting device (10) comprising an LED, a driver (18) for driving the LED, and an electrical connector (14). The lighting device further comprises a thermally triggered switch (16) for prevention of overheating of the electrical connector. The thermally triggered switch is connected in series between the electrical connector and the driver, and the thermally triggered switch is configured to interrupt current in the event of the temperature of the electrical connector meeting a triggering condition. If a significant degree of arcing occurs the electrical connector will heat up such that the triggering condition will be met and the current flow between the electrical connector and the driver will be interrupted. There is also provided a luminaire (20) comprising the tubular LED lighting device.Type: GrantFiled: September 30, 2019Date of Patent: October 27, 2020Assignee: SIGNIFY HOLDING B.V.Inventors: Tian Xiang Wen, Robertus Leonardus Tousain, Yun Wang, Zhigang Pei

Patent number: 8696156Abstract: A LED light bulb (10, 110, 210) having at least one LED (30a-d, 230). Light output from the LED is directed toward an offset scattering optics structure (50, 150, 250) that intersects and scatters the light output. The LED may optionally be paired with a narrow beam optical piece (32a-d, 132a-d, 232) to focus and direct the light output of the LED toward the scattering optics structure. A mounting structure (40, 140, 240a, 240b) may support the scattering optics structure and offset the scattering optics structure from the LED.Type: GrantFiled: December 19, 2011Date of Patent: April 15, 2014Assignee: Koninklijke Philips N.V.Inventors: Chuan Yuan, Yun Li, Mo Shen, Zhigang Pei, Ye Liu
