Patent number: 10661047Abstract: A light-irradiating apparatus which emits light for activating a body is provided. The light-irradiating apparatus includes a blue light source, a white light source, and a controller. The controller controls the white light source and the blue light source, and adjusts irradiation intensities of light emitted by the blue light source and the white light source. The controller causes the white light source to continuously maintain an on state and causes the blue light source to repeat an on state and an off state. The controller causes a sum of the irradiation intensity of the light which is emitted by the white light source and the irradiation intensity of the light which is emitted by the blue light source to be greater than or equal to a biological effect threshold at which light produces an effect of activating the body.Type: GrantFiled: November 17, 2017Date of Patent: May 26, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventor: Ayumu Sato
