[0015] Through the above technical solution, the above first reflective component reflects the light into the exhibition cavity, thereby ensuring that the light passing through the first reflective component can be irradiated into the exhibition cavity, thereby achieving light irradiation of the exhibition cavity.

[0016] The present invention is further configured as follows: the reflective device further comprises a second reflective component for receiving the light reflected by the first reflective component to the outside of the exhibition cavity, and the second reflective component is used to reflect the received light into the exhibition cavity.

[0017] Through the above technical solution, it is possible to ensure that the light that overflows from the first reflective component is received and reflected into the exhibition cavity, thereby ensuring that as much outdoor light as possible can be introduced into the room.

[0018] The present invention is further configured such that: a light splitting element for dispersing light onto the exhibits is also provided in the exhibition cavity.

[0019] Through the above technical solution, the arrangement of the light splitter can disperse the light irradiated into the exhibition cavity to every corner of the exhibition cavity, ensuring that there are no dead angles for the light, and ensuring a better exhibition effect of the exhibits.

[0020] In summary, the present invention has the following beneficial effects: it can guide outdoor light into indoors, and irradiate the light into the exhibition cavity respectively, and achieve the purpose of irradiating the exhibits in the exhibition cavity from multiple angles by dispersing the light. This setting can directly illuminate the exhibits with natural light, restore the original colors of the exhibits, make the display of the exhibits more beautiful, and enhance the experience of visitors.
