the first light-emitting part comprises a first lamp panel for emitting main illumination light;

the second light-emitting part is arranged at one light-emitting side of the first light-emitting part and comprises a cylindrical light guide part and a second lamp panel, the second lamp panel is used for emitting simulated sunlight, and the light guide part is used for guiding the simulated sunlight to one side of the light guide part close to the annular center for emitting; and

the third light-emitting part is arranged on the inner side of the light guide part and comprises a third lamp panel for emitting the imitated blue light.

2. The luminaire of claim 1, wherein the first light emitting portion further comprises:

the first lamp panel is arranged on the first substrate;

the first diffusion plate is arranged on one side, far away from the first substrate, of the first lamp panel and is used for diffusing the illumination light; and

the light transmission cover is arranged on one side, far away from the first lamp panel, of the first diffusion plate and is used for homogenizing the illumination light emitted from the first diffusion plate.

3. The lamp as claimed in claim 1, wherein the first lamp panel is ring-shaped, and the first lamp panel is disposed on one side of an outer sidewall of the light guide portion.

4. The lamp of claim 1, wherein the second light emitting portion further comprises a second substrate, the second substrate is disposed on a side of the first light emitting portion from which light is emitted, and the second light panel is disposed on a side of the second substrate away from the first light emitting portion.

5. The lamp as claimed in claim 4, wherein the light guide portion includes an annular bottom edge and a side wall perpendicular to the bottom edge, and the bottom edge of the light guide portion is configured to receive the pseudo sunlight emitted from the second lamp panel, and emit the pseudo sunlight along a side of the side wall near the annular center of the light guide portion after homogenizing the light.

6. The lamp as claimed in claim 5, wherein the light guide part comprises a cylindrical light guide plate and a cylindrical second diffusion plate, the second diffusion plate is sleeved on the inner side of the light guide plate, the light guide plate is used for guiding the simulated sunlight, and the second diffusion plate is used for diffusing the simulated sunlight emitted from the light guide plate.

7. The luminaire of claim 6, wherein the light guide further comprises a light shielding plate disposed between the light guide plate and the second diffusion plate, for partially shielding the second diffusion plate for controlling the light emitting position of the simulated sunlight on the second diffusion plate, and an included angle between a boundary line of the projection of the edge position of the light shielding plate on the second diffusion plate and the bottom edge is 45 ° ± 2 °.

8. The lamp as claimed in claim 1, wherein the third light panel is disposed along an annular inner sidewall of the light guide portion, and the third light emitting portion further includes a third diffusion plate surrounded by the third light panel, and the third diffusion plate is configured to diffuse and emit the blue sky-like light emitted from the third light panel.

9. The lamp as claimed in claim 8, wherein the third diffusion plate includes a reflective layer, a light guiding layer, and a diffusion layer sequentially stacked, the reflective layer being located at a side close to the first light emitting portion, for emitting the blue sky-light-imitating direction toward a side far from the first light emitting portion.

10. The lamp as claimed in claim 1, further comprising a fourth light emitting portion disposed on a side of the light guiding portion away from the first light emitting portion, for emitting the simulated spot light, wherein the fourth light emitting portion includes a plurality of spot lamps, each of the spot lamps being configured to project one of the simulated spot light.
