Patent number: 9532414Abstract: A trigger-signal-output part sets a burst time cycle to a time period N (integer of two or more) times as long as a constant first cycle, and outputs a trigger signal M (positive integer of N or less) times during an operation period so as to synchronize it with the first cycle, and does not output the trigger signal during a stop period except the operation period of the burst time cycle. Alternatively, a trigger-signal-output part sets a burst time cycle to a time period N times as long as an output cycle of a trigger signal in an operation period, and sets the operation period to a time period M times as long as the output cycle, and sets a stop period except the operation period of the burst time cycle to a time period generated by multiplying the output cycle by a difference between N and M.Type: GrantFiled: July 8, 2014Date of Patent: December 27, 2016Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Kazuhiro Kumada, Masafumi Yamamoto, Yuji Yoshimoto

Patent number: 9320110Abstract: A lighting device includes a voltage conversion circuit having at least a switching element connected to a positive potential side of the output terminals of the DC power source unit, and a drive unit which outputs a drive signal to the switching element. The drive unit has a first impedance element with a first impedance which is determined based on a power consumed by the drive unit before a predetermined time has elapsed after a control power source is supplied. A control capacitor for use in generating the drive signal is charged when the switching element is turned off during an on/off operation of the switching element. The lighting device further includes a second impedance element with a second impedance having a resistance component, which is arranged in a path in which the control capacitor can be charged in DC when the switching element does not perform the on/off operation.Type: GrantFiled: December 18, 2012Date of Patent: April 19, 2016Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Masafumi Yamamoto, Katunobu Hamamoto, Hiroyuki Asano, Hisaya Takikita, Yuji Yoshimoto
