A lighting device having a semiconductor light emitting device using a semiconductor light emitting element, which stably synthesizes output light, suppresses light separation, changes color tone, and makes control for driving the light emitting device as simple as possible. A light emitting device comprising a semiconductor light emitting device and a fluorescent material, and emitting light from the semiconductor light emitting device, and light emitted from the fluorescent material excited by the light emission from the semiconductor light emitting device or excited by light emission from the semiconductor light emitting device; The light emitting color of each semiconductor light emitting device is a lighting device having a semiconductor light emitting device that emits light to the outside, and a light emitting unit in which a plurality of types of light emitting colors are different and integrated are arranged. In the uv chromaticity diagram, the deviation duv from the blackbody radiation trajectory is -0.02. duv It falls in the range of 0.02, and each output light from the light emitting part in which the some kind of semiconductor light emitting device was integratedly arrange | positioned is mixed, and it exits outside. |
