The present invention belongs to the technical field of optical devices that imitate the light and shadow effects of skylights under natural light, and discloses a sunlight reflection device for simulating skylights on the roof of a house, including a light box outer frame, a skylight light outlet plate fixedly installed on the top of the light box outer frame, three adjustable LED light strips fixedly installed on the inner cavity wall of the light box outer frame, and a first transparent plate and a second transparent plate fixedly installed on the bottom of the inner cavity of the light box outer frame. The present invention installs a shading memory foam close to the position between the adjustable LED light strip and the light homogenizing plate on the light path between the adjustable LED light strip and the light homogenizing plate. When the adjustable LED light strip is irradiated onto the shading memory foam, the light blocked by the shading memory foam can produce a shadow with a clear boundary on the light homogenizing plate, so that it can simulate the projection effect of the skylight frame under the incident angle of sunlight, so that the irradiation effect has a high degree of simulation and the user experience is better.
