The light guide post 122 includes a light guiding part 1221 and a light emitting part 1222 at its end. The light guide 12 cooperates with the light guiding part 1221 to guide all or part of the light emitted by the LED bead 11 to the light emitting part. Part 1222; Each flexible circuit board 1 is connected to a wire 15, adjacent flexible circuit boards 1 are electrically connected to each other through the wire 15, and at least one flexible circuit board 1 has a controller 16 electrically connected to the end of the wire 15. The controller 16 can control the opening and closing of multiple lamp beads 11 on the flexible circuit board 1 through the corresponding wire 15, so that the driver can control the starlight roof to form different starlight patterns as needed; In this embodiment, the light guide column 122 is pre-embedded in the interlayer of the roof during assembly, and the bottom of the interlayer has a light-transmitting hole corresponding to the light guide column 122.
[0038] like Figures 5-9As shown, the outer walls of the light guide 12 and the light guide section 1221 are coated with a light-shielding layer 123.
