Abstract: A lighting apparatus to be installed in an area adjacent to land is provided. The lighting apparatus includes a plurality of light sources disposed on a board and further includes a light shield. The light shield blocks a portion of light emitted from the light sources. The portion of light has a predetermined wavelength. The light shield is disposed on the board closer to the land than at least a light source disposed closest to the land among the light sources. The light shield has a shape which sends, to the land, first emission light included in the light emitted from the light sources. The shape avoids sending, to the land, second emission light included in the light emitted from the light sources. The first emission light passes through the light shield. The second emission light does not pass through the light shield.

Abstract: A lighting apparatus includes first light emitting elements and second light emitting elements having chromaticity values in a same chromaticity range. A ratio of a greatest value of a spectral distribution of combined light in a range of 500 nm to 560 nm inclusive to a smallest value of the spectral distribution of the combined light in a range of 500 nm to 650 nm inclusive is 0.85 or less. The combined light is a combination of light emitted by the first light emitting elements and light emitted by the second light emitting elements.

Abstract: A lighting apparatus is provided. The lighting apparatus includes a first light distributor which illuminates a predetermined region, and a second light distributor which illuminates a periphery of the predetermined region. The first light distributor includes a first light emitting element having a spectral emission characteristic defined by a correlated color temperature of light being at least 5400 K and at most 7000 K, Duv being in a range of −6 to 5 inclusive, a chroma value calculated using a calculation method specified by the CIE 1997 Interim Color Appearance Model (Simple Version) being 2.7 or less, and a general color rendering index Ra being 80 or more. The second light distributor includes a second light emitting element having a spectral emission characteristic defined by a correlated color temperature of light being lower than the correlated color temperature of the light emitted by the first light emitting element.

Abstract: Provided is a vehicle front lamp for use in a vehicle, including: a first white light source that emits first white light; a second white light source that emits second white light having a feeling of contrast index different from that of the first white light by at least 10; and a controller that controls light intensity of the first white light and light intensity of the second white light, in which chromaticity of the first white light and chromaticity of the second white light are each within a 5-step MacAdam ellipse, the first white light source and the second white light source are disposed in the vehicle front lamp so that the first white light and the second white light overlap each other on a certain illuminated surface, and the controller temporally changes a light intensity ratio between the first white light and the second white light.

Abstract: An illumination apparatus includes a first LED, a second LED, and a control unit. The first LED emits white light. The second LED emits white light having a correlated color temperature lower than that of the white light emitted from the first LED and a chromaticity deviation Duv higher than that of the white light emitted from the first LED. The control unit changes a light output ratio of the first LED and the second LED. The first LED emits the white light of the correlated color temperature ranging from 1563K to 4500K and the chromaticity deviation Duv ranging from −1.6 to −12. The second LED emits the white light of the correlated color temperature ranging from 1563K to 4500K and the chromaticity deviation Duv ranging from +10 to −1.6.
