Patent ID: 10222007

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.
