Patent number: 9635729Abstract: An illumination device includes a first light source and a second light source, a sensor, and a controller. The controller repeats a plurality of operation cycles, one operation cycle being a set of a first period in which only a detection target light source is caused to emit light and a second period in which the first light source and the second light source are caused to emit light. The sensor outputs detection values of detected light amounts in the first period. The controller controls the light source such that light amount of the light source fall in a target range, based on a detection result that corresponds to a value corresponding to the detection values of the light amount detected a predetermined number of times.Type: GrantFiled: September 8, 2016Date of Patent: April 25, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Nobuyuki Matsui, Youji Tachino

Patent number: 9227727Abstract: A lighting system includes a lighting apparatus provided along one side of an aisle and a specular reflection plate provided along the other side of the aisle to reflect the light emitted from the lighting apparatus toward a region where the lighting apparatus is provided. According to the above configuration, the lighting apparatus can illuminate the region where the lighting apparatus is provided. Therefore, it is possible to effectively illuminate a cabin of an aircraft with less lighting apparatuses as compared to conventional lighting apparatuses which are provided along both sides of the aisle. Moreover, since the number of the lighting apparatuses can be reduced, it is possible to improve fuel efficiency of the aircraft by reducing the total weight of the aircraft.Type: GrantFiled: April 11, 2014Date of Patent: January 5, 2016Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Tadasi Nisimura, Youji Tachino, Atsushi Motoya, Takashi Ohta, Hiroshi Kido, Junichi Hasegawa, Shigeo Gotoh, Nobuyuki Matsui, Tadashi Murakami

Patent number: 9127815Abstract: This lighting apparatus includes three or more LEDs arranged in a row. Each of the LEDs emits light of a color different from that of an LED adjacent to itself, and the LEDs include an LED having a relatively wide light distribution angle and others of the three or more LEDs each having a relatively narrow light distribution angle. The one LED is arranged in an inner portion in the row of the other LEDs. In this configuration, light emitted from the one LED is mixed well with lights emitted from the respective other LEDs adjacent to the one LED, and thus, color unevenness of illuminating light can be reduced.Type: GrantFiled: April 11, 2014Date of Patent: September 8, 2015Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Youji Tachino, Atsushi Motoya, Takashi Ohta, Hiroshi Kido, Junichi Hasegawa, Shigeo Gotoh, Nobuyuki Matsui, Tadashi Murakami, Tadasi Nisimura
