Publication number: 20160270189Abstract: An illumination system includes a light projection device, an illuminance measurement unit, a lighting device, and a control device. The light projection device projects an image to a space. The illuminance measurement unit measures an illuminance value of a location where the illuminance measurement unit is placed in the space. The lighting device has a dimming function for illuminating the location in the space with a brightness. The control device includes an illuminance setting unit, a difference calculation unit, and an illumination light adjusting unit. The illuminance setting unit sets an illuminance value of the location. The difference calculation unit calculates a difference between the illuminance value set by the illuminance setting unit and the illuminance value measured by the illuminance measurement unit. The illumination light adjusting unit adjusts a brightness of the lighting device such that the difference calculated by the difference calculation unit is reduced.Type: ApplicationFiled: March 8, 2016Publication date: September 15, 2016Applicant: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Ryo KAWAMURA, Kentaro YAMAUCHI, Kohji HIRAMATSU, Akihiro KISHIMOTO, Tatsumi SETOMOTO

Patent number: 7432670Abstract: Even if a DC output voltage of a step-down chopper circuit (3) is lowered from a value in a non-lighted state or a no-load state due to a discharge occurring between conductors (105a) in a cable (104), the turn on detection circuit (26a) can discriminates between lighted and non-lighted states without erroneously determining such a discharge as a discharge in a discharge lamp (4). This allows an operation of the timer (29) to be continued, so that high-voltage pulses are intermittently applied to prevent continuous discharge between the conductors (105) and abnormal heat generation in the cable (104). Further, even if a discharge occurs in an outer tube of the discharge lamp (4), the turn on detection circuit (26a) never erroneously discriminates this discharge as the lighted state. Thus, the lighting device of the present invention can suppress abnormal heat generations in the components and a socket (102).Type: GrantFiled: November 24, 2004Date of Patent: October 7, 2008Assignee: Matsushita Electric Works, Ltd.Inventors: Koji Yamashita, Akihiro Kishimoto, Koji Noro, Toshiaki Sasaki, Noriyuki Fukumori

Patent number: 7141937Abstract: A full bridge circuit including four switching elements (Q1 to Q4) is alternated with a high switching frequency and a series-connected resonance circuit (5) including an inductor (L2) and a capacitor (C2) is made to resonate at a switching frequency of the full bridge circuit multiplied by an integer (for example, frequency multiplied by three), thereby generating a high voltage pulse for start up. After a high-pressure discharge lamp (DL) is started up, the full bridge circuit is alternated with a low switching frequency so as to operate as a step-down chopper for inverting the output polarity, thereby stably supplying rectangular wave voltage of low frequency to the high-pressure discharge lamp (DL) via a filter circuit including an inductor (L1) and a capacitor (C1).Type: GrantFiled: September 26, 2003Date of Patent: November 28, 2006Assignee: Matsushita Electric Works, Ltd.Inventors: Jun Kumagai, Akihiro Kishimoto, Hirofumi Konishi
