Light-emitting apparatus
First Claim
1. A light-emitting apparatus which emits light for activating a body, the light-emitting apparatus comprising:
- a blue light source;
a white light source; and
a controller which controls the white light source and the blue light source and which adjusts an irradiation intensity of light emitted by the blue light source and an irradiation intensity of light emitted by the white light source, whereinthe 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, andthe controller divides a duty cycle of the blue light source by a first irradiation time for activating the body to calculate a second irradiation time, and causes the blue light source and the white light source to emit light for the second irradiation time by controlling the blue light source and the white light source.

Abstract
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.

13. A light-emitting apparatus which emits light for activating a body, the light-emitting apparatus comprising:
-
a blue light source; a white light source; a controller which controls the white light source and the blue light source and which adjusts an irradiation intensity of light emitted by the blue light source and an irradiation intensity of light emitted by the white light source, wherein 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; a first light-emitting module; a second light-emitting module; a casing which houses the first light-emitting module and the second light-emitting module, and which includes an opening; and a light-transmissive plate which covers the opening in the casing, wherein the first light-emitting module and the second light-emitting module are approximately orthogonal to the opening, and disposed in the casing such that the first light-emitting module and the second light-emitting module emit light toward each other. - View Dependent Claims (14, 15)
