a first light emitter, which is a first light emitting region having a predetermined shape, having a first light beam angle determined by a first light emitted from the first light emitter;

a second light emitter, which is a second light emitting region having a predetermined shape, having a second light beam angle determined by a second light emitted from the second light emitter;

a wavelength converter comprising a first wavelength converter disposed on the first light emitter and a second wavelength converter disposed on the second light emitter; and

an isolation trench disposed between the first light emitting region and the second light emitting region,

wherein

the second light emitter is spaced apart from the first light emitter by the isolation trench, shares a same center as the first light emitter, and surrounds the first light emitter,

the isolation trench comprising a first isolation trench and a second isolation trench disposed between the first wavelength converter and the second wavelength converter, the second isolation trench has a region overlapped with a region of the first isolation trench, and the first wavelength converter and the second wavelength converter are spaced apart from each other by the second isolation trench, and

the first light beam angle is different and is narrower than the second light beam angle,

the second isolation trench comprising materials for spreading and mixing light emitted from the first wavelength converter and the second wavelength converter.
