Patent number: 8933645Abstract: A lighting control system includes a central control apparatus and plural luminaires. A light color of each of the plural luminaires can be changed and each of them is assigned to one of plural groups to which different light colors are assigned or is duplicately assigned to the plural groups. The central control apparatus includes a control part and an output part. The control part generates control signals for controlling the light colors of the plural luminaires and causes a light color of a luminaire overlapping with the plural groups or an adjacent luminaire to become an intermediate light color between the assigned light colors for the respective plural groups when the plural luminaires assigned to the plural groups are lit and controlled. The output part outputs the control signals generated by the control part to the plural luminaires.Type: GrantFiled: February 28, 2013Date of Patent: January 13, 2015Assignee: Toshiba Lighting & Technology CorporationInventor: Hidenori Nishigaki

Patent number: 8878439Abstract: According to one embodiment, a lighting control system includes a plurality of luminaire, a sensor device, a luminance sensor, and a lighting control unit. The luminaires are set in a lighting space. The sensor device detects presence of a person in the lighting space. The luminance sensor detects indirect luminance in a predetermined position in the lighting space by the luminaire. The lighting control unit subjects the luminaire to lighting control such that the indirect luminance detected by the luminance sensor does not fall below a predetermined value in a position where the sensor device detects presence of the person.Type: GrantFiled: November 29, 2012Date of Patent: November 4, 2014Assignee: Toshiba Lighting & Technology CorporationInventors: Yoko Noguchi, Tomoko Ishiwata, Makoto Kawagoe, Takayuki Ono, Kenji Takahashi, Hidenori Nishigaki, Junko Takahashi, Shigehisa Kawatsuru, Hitoshi Kawano, Fumie Iwata

Publication number: 20140300277Abstract: Plural luminaires are installed in a lighting space surrounded by a wall part. A sensor equipment detects existence or nonexistence of a person in the lighting space. If existence of a person in the lighting space is detected, the sensor equipment detects a direction of the person. The sensor equipment detects a distance between the wall part positioned in front of the direction of the person and the person. A lighting control unit selectively switches between a first control for performing lighting control of the luminaires to illuminate the wall part positioned in front of the direction of the person if the detected distance is a specified distance or less, and a second control for performing lighting control of the luminaires to reduce brightness at a place as the place becomes farther from a position of the person if the detected distance is larger than the specified distance.Type: ApplicationFiled: April 1, 2014Publication date: October 9, 2014Applicant: TOSHIBA LIGHTING AND TECHNOLOGY CORPORATIONInventors: Takayuki ONO, Tomoko ISHIWATA, Yoko NOGUCHI, Makoto KAWAGOE, Kenji TAKAHASHI, Hidenori NISHIGAKI, Junko TAKAHASHI, Shigehisa KAWATSURU, Hitoshi KAWANO, Fumie IWATA, Katsusuke UCHINO

Publication number: 20140042914Abstract: According to one embodiment, a lighting control unit turns on luminaires corresponding to a presence area among four detection areas adjacent to one another in a predetermined direction and a crossing direction. If there is one presence area among the four detection areas, the lighting control unit relatively reduces the brightness of the luminaires corresponding to remaining three absence areas. If there are two presence areas among the four detection areas, the lighting control unit relatively reduces the brightness of the luminaires on a side adjacent to the presence areas among the luminaires corresponding to the remaining two absence areas and turns off the remaining other luminaires. If there are three presence areas among the four detection areas, the lighting control unit turns off the luminaires corresponding to the remaining one absence area.Type: ApplicationFiled: October 30, 2012Publication date: February 13, 2014Applicant: Toshiba Lighting & Technology CorporationInventors: Yoko NOGUCHI, Tomoko ISHIWATA, Makoto KAWAGOE, Takayuki ONO, Kenji TAKAHASHI, Hidenori NISHIGAKI, Junko TAKAHASHI, Fumie IWATA, Shigehisa KAWATSURU, Hitoshi KAWANO, Katsusuke UCHINO
