As the preferred technical scheme of this embodiment, LED unit module includes the PCB board, and the LED lamp pearl of having arranged on the PCB board in array still has the through-hole between LED lamp pearl and the LED lamp pearl, can play sound transmission and radiating effect. The stereo set can be hung on the main steel structure 1, and sound can immerse the sense for spectator through the through-hole on the LED unit module. The luminous surface of the LED unit module faces the center of the sphere and is used for playing display pictures, and sound emitted by audiences can be reflected by the concave dome, so that a plurality of through holes are formed in each LED display module to avoid sound reflection. When the sound equipment is arranged on the back (periphery) of the LED unit module, the through hole can also play a sound transmission role, and the picture and the sound are ensured to be synchronous.

As the preferred technical scheme of this embodiment, still be provided with and hang ladder 6, it is circular-arc to hang ladder 6, and the top of hanging ladder 6 is formed with two at least couples 61, hangs 6 accessible couples 61 of ladder and hangs on main steel constructs 1's surface, and maintainer can climb and hang ladder 6 and overhaul the vault curtain, and is very convenient.

The dome of this embodiment adopts the mounting means of console mode, and its back occupation space is little, is suitable for the less place in space, and its steel construction can be dismantled into less unit to conveniently adjust and carry. The pole of the assembled dome is located at the top end, so that the LED display layer 5 is not prone to dust falling, and cannot be damaged due to falling objects in high altitude.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
