Abstract: A lighting apparatus includes an LED chip that emits primary light, and phosphor particles that emit secondary light by being excited with the primary light. The lighting apparatus emits light including the primary light and the secondary light. The light has an emission spectrum having a first peak in a wavelength ranging from 420 nm to 460 nm, a second peak in the wavelength ranging from 530 nm to 580 nm, a third peak in the wavelength ranging from 605 nm to 655 nm, a first trough in the wavelength ranging from 440 nm to 480 nm, and a second trough in the wavelength ranging from 555 nm to 605 nm.

Abstract: A light-emitting device includes a light emission controller which causes first and second light-emitting element groups to emit light, by supplying undulating voltage to the first and second light-emitting element groups. The light emission controller supplies the undulating voltage to the first light-emitting element group, during a first period in which a magnitude of the undulating voltage is greater than a first predetermined value and at most a second predetermined value. The second predetermined value is less than a maximum value of the undulating voltage. The light emission controller supplies the undulating voltage to the first and second light-emitting element groups during a second period in which the magnitude of the undulating voltage is greater than the second predetermined value. The first light-emitting element group surrounds the second light-emitting element group.

Abstract: A light-emitting device includes: a substrate having a principal surface which includes a resist film; a first light-emitting element line mounted above the principal surface; a second light-emitting element line mounted above the principal surface; a first sealing member which is provided on the resist film and seals the first light-emitting element line; and a second sealing member which is provided on the resist film and seals the second light-emitting element line. In the light-emitting device, a color of light which the first sealing member emits as a result of light emission of the first light-emitting element line is different from a color of light which the second sealing member emits as a result of light emission of the second light-emitting element line, and the principal surface includes a region between the first sealing member and the second sealing member in which the resist film is not formed.

Abstract: A light emitting module includes a first light emitter that emits light having a first color temperature and a second light emitter that emits light having a second color temperature higher than the first color temperature. The first light emitter includes a first light emitting element and a first sealant. The first sealant seals the first light emitting element and includes a first wavelength converter that converts a wavelength of light emitted by the first light emitting element. The second light emitter includes a second light emitting element and a second sealant. The second sealant seals the second light emitting element and includes a second wavelength converter that converts a wavelength of light emitted by the second light emitting element. In a plan view, the first light emitting element has a surface area greater than a surface area of the second light emitting element.
