The shading frame group 20 includes a top frame body 21 , four pillars 22 and a bottom frame body 23 . The top frame body 21 of the first embodiment is a square frame, but its shape is not limited to this. The four pillars 22 are opaque pillars, which are arranged above the base 10 and support the top frame body 21 , but the number of the pillars 22 is not limited to four, and can be changed to more than one according to design requirements. The bottom frame body 23 is a square frame which connects the base 10 and the bottoms of the four pillars 22 .

The four light display lines 40 are wires, which are used to simulate light and display the traveling direction of the light. One end is connected to the shadow display group 30; however, the number of the light display lines 40 is not limited to four. Can be changed according to design requirements. The shadow display group 30 is a plane structure with obvious colors, such as lines or patterns, and is disposed on the base 10 . The shape of the shadow display group 30 corresponds to the projection of the shading frame group 20 along the light display line 40 .

The light direction indicator 50 is used to indicate the traveling direction of the light simulated by the light display line 40 , and the light direction indicator 50 is connected to the base 10 . The light direction indicator 50 includes a rod body 51 and a light direction extension line 52 . The rod body 51 is a wood, plastic or acrylic rod, which is connected to the base 10 . The rod body 51 further includes a top end 511 of the rod body. The light direction extension line 52 is a wire, one end of the light direction extension line 52 is connected to the top end 511 of the rod body, and the other end of the light direction extension line 52 is connected to the top frame body 21 of the shading frame group 20 .
