In some embodiments, the holographic LED light bar 101 extends from the center of rotation of the lamp panel 1 to the edge of the lamp panel 1.

In some embodiments, two holographic LED light bars 101 are provided; two LED lamp strips 101 for holography are arranged in a cross shape.

In some embodiments, the illumination LED beads 102 are arranged in an array.

As an example, as shown in fig. 1 (b), two hologram LED light bars 101 are arranged perpendicular to each other in a cross shape across the rotation center of the lamp panel 1, and in this case, the hologram LED light bar 101 divides the lamp panel 1 into 4 regions, and each region is provided with an LED bead 102 for illumination.

In some embodiments, a wireless power coil is further disposed on the lower lamp housing 106.

Optionally, the first wireless power supply coil 301 is disposed on the second plate surface of the lamp panel 1 through the lower lamp cover 106. When the 3D holographic drive motor 2 rotates at a high speed, the lamp panel board 1 is driven to rotate at a high speed, but the lamp panel board 1 needs to be powered at the same time, and the wireless power supply coil can be adopted for supplying power for the present disclosure. In this case, correspondingly, the 3D holographic driving motor 2 is provided with a second wireless power supply coil 302 on a side close to the lamp panel 1 to cooperate with the first wireless power supply coil 301 provided on the lamp panel 1.

Referring to fig. 5, a schematic structural diagram of a 3D holographic drive motor according to an embodiment of the present disclosure is shown.

The convex part 201 of the 3D holographic drive motor is used for being connected with the lamp panel board 1 through the lower lamp shade 106, and the concave part 202 of the 3D holographic drive motor is used for bearing the second wireless power supply coil 302 so as to cooperate with the first wireless power supply coil 301 arranged on the lamp panel board 1.

Reference is made to fig. 6, which is a schematic structural diagram of a control structure of a holographic projection apparatus provided in an embodiment of the present disclosure.

The 3D holographic drive motor side supplies power to the components and the control assembly on the lamp panel side through a coil (wireless power supply coil), and transmits control signals to the components and the control assembly on the lamp panel side through infrared signals so as to control the lamp strip and the lamp bead on the lamp panel.

The 3D holographic drive motor side comprises a power supply end, a remote control on-off unit, a motor control unit, a key detection unit and a key signal transmission unit.

The lamp panel side comprises a 3D holographic display control unit, an LED illuminating lamp control unit and an infrared remote control signal processing unit.

In the above embodiment, the components on the lamp panel 1 are powered by the wireless power supply coil, but the application is not limited to this, and for example, in one possible implementation, the components on the lamp panel 1 may be powered by an electrical rotary joint.

Refer to fig. 7, which is a schematic structural diagram of a housing according to an embodiment of the disclosure.

In some embodiments, further comprises a housing 401; the cover 401 covers the lamp panel 1 and the 3D hologram driving motor 2.

The housing 401 can play the roles of reducing noise, preventing water and dust and protecting safety. When holographic projection is performed, the lamp panel 1 rotates at a high speed, friction between the lamp panel 1 and air generates large noise, and noise of the 3D holographic driving motor 2 is relatively large, and the housing 401 is arranged to effectively reduce the noise. Meanwhile, when the lamp panel board 1 rotates at a high speed, if foreign objects fall into the rotating surface of the lamp panel board 1, the lamp panel board 1 is easily damaged, if a human body is close to the rotating surface of the lamp panel board 1, the human body is easily injured, and the housing 401 can play a role in protection to a certain extent.

In some embodiments, the housing 401 is transparent to enable clear holographic projection of the light panel 1. As an alternative embodiment, the cover 401 is made of acrylic. The acrylic plate is specially treated organic glass and is a replacement product of the organic glass, and the housing 401 made of the acrylic plate has good light transmission performance, pure color, excellent rigidity and strength and excellent chemical resistance. In this case, the front plate can play a role of protection and will not interfere with the holographic projection of the lamp panel 1.

The above embodiment has been described by taking the case 401 as an example of a cylindrical shape, but the present application is not limited thereto, for example, in one possible embodiment, the case 401 has a polygonal columnar structure including a triangular column, a square column, a pentagonal column, or a hexagonal column.

In some embodiments, a light adjusting film 402 is further disposed on the housing 401; when holographic projection is carried out, the light adjusting film is in a transparent state; when the lighting is performed, the light adjusting film 402 is in an opaque state; the light adjusting film 402 is transparent when it is powered on and opaque when it is powered off.

Optionally, the dimming film 402 is an electrically controlled dimming film. The electric control dimming film is formed by clamping a layer of liquid crystal film between two pieces of glass, and when the liquid crystal film is electrified, the glass becomes transparent. By controlling the on-off of the power supply, the electric control dimming film can be freely switched between transparency and opacity. In this case, the light adjusting film 402 is in a transparent state when it is powered on and in an opaque state when it is powered off. When holographic projection is performed, the light adjusting film 402 is powered on; when lighting is performed, the dimming film 402 is powered off.

The above embodiment has been described by taking the light adjusting film 402 as an electrically controlled light adjusting film as an example, but the application is not limited to this, and for example, in one possible implementation, the light adjusting film 402 is an optically controlled light adjusting film. The light-operated dimming film is transparent at normal temperature, can be changed into opaque ground glass from transparent glass when the temperature is increased, and can be changed back into transparent glass when the temperature is reduced. In this case, the light adjusting film 402 is transparent at normal temperature and opaque at high temperature.
