[0027] Among them, the mounting seat 12 is integrally formed on the top of the conical base plate 2 and located outside the through hole 10, and the mounting cap 3 is screwed on the top of the mounting seat 12;

[0028] Specifically, the outer wall of the mounting seat 12 is provided with external threads 14, and the inner wall of the mounting cap 3 is provided with internal threads 15, and the external threads 14 and the internal threads 15 are engaged with each other.

[0029] Secondly, the fixed seat 5 is fixedly welded on the bottom of the base 1, and the mounting hole 6 is formed through the periphery of the fixed seat 5.

[0030] In addition, the transparent protective cover 13 is fixedly installed on the outer wall of the conical base plate 2 and located outside the lamp bead 4.

[0031] In this embodiment, the tapered substrate 2 is sleeved on the screw rod 9 through the through hole 10, and then the nut 11 is screwed above the screw rod 9, so as to fix the tapered substrate 2 on the base 1. The fixing seat 5 and the mounting hole 6 can use fasteners such as bolts to firmly install the display module on the required plane. The transparent protective cover 13 can effectively prevent the lamp beads 4 from being impacted by external force, dust and moisture, prolong the service life of the lamp beads 4. At the same time, the transparent protective cover 13 should have good light transmittance to ensure that the light of the lamp beads 4 can normally transmit out, without affecting the display effect. The rotational arrangement of the lamp beads on the tapered substrate 2 can make the LED display module can play content in all directions, mainly installed on the ground to play related content for the convenience of people's watching. The audience has the opportunity to see the complete display information from the front, side or slightly inclined angle, greatly improving the visual range.

[0032] Embodiment two

[0033] Reference Fig. 2 The LED display module with rotational arrangement includes a base 1 and a tapered substrate 2.

[0034] The base 1 is internally provided with a cavity, and a through hole 16 is formed through the top of the base 1. A heat dissipation port 17 is formed through the outer wall of the base 1.

[0035] In this embodiment, the cavity in the base 1 can play a role in heat dissipation and weight reduction. The through hole 16 at the top can make the air circulate and conduct the heat generated by the tapered substrate 2 and the lamp beads 4 to the cavity in the base 1. The heat dissipation port 17 at the outer wall can dissipate the heat to the surrounding environment, thereby effectively reducing the temperature of the display module and ensuring its normal operation. In addition, the heat dissipation port 17 can also play a role in ventilation, preventing dust and moisture from accumulating in the base 1 and affecting the performance and life of the display module. A dust screen can be arranged at the heat dissipation port 17 to prevent dust from entering the base 1. At the same time, a heat dissipation fan or other heat dissipation device can be considered to be arranged in the base 1 to further improve the heat dissipation effect.

[0036] Working principle: the LED display module arranged in rotation mainly comprises a base 1 and a conical base plate 2, the conical base plate 2 is sleeved on the screw rod 9 at the top center of the base 1 through the through hole 10, and is fixedly connected with the base 1 by screwing the nut 11 above the screw rod 9, the servo motor 7 embedded at the top center of the base 1 is the power source of the whole module, the rotating shaft 8 at the top of the servo motor 7 is welded with the screw rod 9, and provides power for the rotation of the conical base plate 2, when the servo motor 7 receives a working signal, starts to operate, the rotation of the motor drives the rotating shaft 8 to rotate, and then the screw rod 9 connected with the rotating shaft 8 rotates synchronously, since the screw rod 9 penetrates the through hole 10 at the top of the conical base plate 2 and the conical base plate 2 is fixed on the screw rod 9 through the nut 11, the rotation of the screw rod 9 will be converted into the torque of the conical base plate 2, so that the conical base plate 2 is driven to rotate around the axis of the screw rod 9, a plurality of groups of lamp beads 4 are arranged and installed on the outer wall of the conical base plate 2 in a regular manner, the lamp beads 4 are key components for realizing the display function, when the lamp beads 4 receive a display signal, they will emit light according to the preset program or control instruction, since the conical base plate 2 is in a rotating state, the position and angle of the lamp beads 4 relative to the observer change constantly in the rotating process, in daily use, the transparent protective cover 13 fixedly installed on the outer wall of the conical base plate 2 and outside the lamp beads 4 plays an important protection role, it can prevent the lamp beads 4 from being damaged by external force impact, and blocks dust and moisture from entering the area of the lamp beads 4, effectively prolongs the service life of the lamp beads 4, and moreover, the transparent protective cover 13 has good light transmittance, ensures that the light emitted by the lamp beads 4 can normally transmit out, does not affect the display effect, and when maintenance is needed, the mounting cap 3 can be rotated and removed, then the nut 11 is rotated and removed, and then the conical base plate 2 can be taken out upwards to complete the disassembly, the operation is simple, and the maintenance operation of the module in the later period is facilitated.

[0037] It can be understood that the lamp beads and the servo motor driving mode in the utility model can be driven in the mode of external power supply line, the lamp beads and the servo motor can be programmed and controlled by the main control system, and the control principle is realized by the existing control technology.
