The invention relates to a starry
sky top
scintillation machine, which comprises
LED lamp beads, a
control circuit, a blocking piece, a stepping motor and an
optical fiber bundling
pipe, the blocking piece is positioned between the
LED lamp beads and the
optical fiber bundling
pipe, and the
scintillation machine is characterized in that the blocking piece is mounted on a driving shaft of the stepping motor, the
LED lamp beads are arranged around the driving shaft of the stepping motor, a central avoidance area is arranged on the
optical fiber bundling
pipe, and the central avoidance area corresponds to the driving shaft in the center of the blocking piece and the invalid area around the driving shaft. The
machine has the advantages of being small in size, reliable in operation and the like, and can be used for automotive interior starry
sky roofs.
