The first light emitting assembly 30 is disposed in the mounting cavity, the light emitting portion of the first light emitting assembly 30 is disposed toward the diffusion plate 20, and the first light emitting assembly 30 is configured to emit blue light. The second light emitting assembly 40 is disposed in the mounting cavity, the light emitting portion of the first light emitting assembly 30 is disposed in an inclined manner, the light emitting portion of the second light emitting assembly 40 is disposed toward the parallel light transmitting area of the housing 10, the parallel light transmitting area of the housing 10 is located on the side plate 13 or the bottom light emitting plate 12, and the second light emitting assembly 40 is configured to emit parallel light and emit the parallel light from the parallel light transmitting area of the housing 10.

By adopting the lighting fixture provided by the embodiment, the blue light emitted by the first light emitting assembly 30 is diffused by the diffusion plate 20 and then emitted from the bottom light emitting plate 12, so as to simulate the effect of a blue sky. The second light-emitting assembly 40 emits parallel light, and the side plate 13 can also be arranged as a side light-emitting surface, so that the parallel light is obliquely emitted to the ground or the wall of a room from the side light-emitting surface or the bottom light-emitting plate 12 to simulate the effect of generating light spots when outdoor light is emitted into the room, and the irradiation characteristics of the sunlight can be conveniently and well simulated on the whole. The thickness of the housing 10 required for the first light emitting assembly 30 to emit blue light through the diffusion plate 20 in this embodiment is small, and the second light emitting assembly 40 can further reduce the overall thickness of the housing 10 by emitting parallel light from the side surface, so that the overall thickness of the lighting fixture is small, and the installation and the use are convenient.

Specifically, the first light emitting module 30 may be disposed between the top mounting plate 11 and the diffusion plate 20 so that the light emitting portion of the first light emitting module 30 is disposed toward the diffusion plate 20. Alternatively, the first light emitting module 30 is disposed at a side portion of the diffusion plate 20, and the light emitting portion of the first light emitting module 30 is disposed toward the diffusion plate 20, so that the thickness of the whole housing 10 can be reduced, the compactness of the structural arrangement can be improved, and the installation and the use can be facilitated better.
