Claim:
1. An illumination apparatus, comprising: a first light guide plate comprising a first light-emitting surface, a first side surface connected to the first light-emitting surface, a first micro structure pattern, a first circuit layer integrated with the first side surface, and at least one first color light source disposed on the first side surface and electrically connected to the first circuit layer, wherein light emitted by the first color light source enters the first light guide plate and is induced by the first micro structure pattern to orthogonally emit from a first region of the first light-emitting surface; a second light guide plate comprising a second light-emitting surface, a second side surface connected to the second light-emitting surface, a second micro structure pattern and a second circuit layer integrated with the second side surface, and at least one second color light source disposed on the second side surface and electrically connected to the second circuit layer, wherein light emitted by the second color light source enters the second light guide plate and is induced by the second micro structure pattern to orthogonally emit from a second region of the second light-emitting surface, and a projection area where the second region orthogonally projected onto the first light-emitting surface is not overlapped with the first region; and a base comprising a cavity for at least accommodating the first side surface of the first light guide plate and the second side surface of the second light guide plate, and electrically connected to the first circuit layer and the second circuit layer.
