A light emitting device having high color rendering properties and capable of realizing an arbitrary light projecting pattern is provided. A light emitting device includes a light emitting unit, a lens, and an operation control unit. The operation control unit changes a relative position of the lens with respect to the light emitting unit, thereby changing the light emitting unit. The irradiation position and spot size of the laser beam are changed. [Selection] Figure 1 |
