Abstract: A photocosmetic device includes a first light source unit, a second light source units, a housing, and a light exit surface. The first light source unit includes a light source. The second light source unit includes a light source. The first light source unit and the second light source unit are housed in the housing. Light of the light source of each of the first light source unit and the second light source unit is emitted from the light exit surface to an outside of the housing. An optical axis of the first light source unit and an optical axis of the second light source unit are non-parallel to each other and cross each other on an outside of the housing.

Abstract: Light-emitting depilation device includes light source, skin cooling unit that cools skin, and push switch including pressing unit that surrounds an outer periphery of light source and skin cooling unit. When pressing unit is not pressed, pressing unit is protruding from a surface of skin cooling unit, the surface being a surface that is to be brought into contact with the skin, toward an opposite side of light source with respect to skin cooling unit. Upon being pressed, a surface of pressing unit pressed by the skin moves closer to light source with respect to skin cooling unit. Push switch switches to cause light source to emit and not to emit light in such a manner that light is emitted from light source at least for a part of the time while pressing unit is pressed, and light is not emitted from light source while pressing unit is not pressed.

Abstract: A hair cutting device according to the present disclosure comprises an optical waveguide. The optical waveguide comprises a light irradiator. The light irradiator irradiates hair protruding from the skin with light to cut the hair. The refractive index of the light irradiator is smaller than the refractive index of the surface of the skin. As a result, options such as the material of the optical waveguide and the like can be increased. Furthermore, for example, when the skin is appropriately irradiated with light from the light irradiator, an action on the skin such as sterilization or activation can also be expected.

Abstract: A hair cutting device according to the present disclosure comprises an optical waveguide. The optical waveguide comprises a light irradiator for irradiating hair protruding from a skin with light to cut the hair. At least at a time of cutting the hair, a power density of light passing through the optical waveguide is more than or equal to 50 kW/cm2. This makes it easy to efficiently cut hair with light with which the light irradiator irradiates the hair. That is, it is possible to apply sufficient light energy for cutting the hair from the optical waveguide to the hair, and it is possible to cut the hair in a relatively short time. Therefore, for example, a width increases such as a thickness or hardness of hair that can be cut.

Abstract: A light source device includes: a semiconductor light-emitting element; a converging optical system which converges the excitation light emitted from the semiconductor light-emitting element; and a wavelength conversion element to which the excitation light is emitted. The wavelength conversion element includes: a first wavelength conversion region where main light enters; and a second wavelength conversion region which is disposed in the surrounding region of the first wavelength conversion region and where the excitation light excluding the main light enters. The wavelength conversion efficiency in the second wavelength conversion region is lower than the wavelength conversion efficiency in the first wavelength conversion region.
