3D hologram involves a technique known as optical holography. A hologram is created by superimposing a reference beam of light onto the wavefront of the object being recorded. This creates an interference pattern that is captured on a physical medium (like a photographic plate or film). When the amplitude and phase of the light waves reflected from the object, the derived pattern makes the hologram unique, and the light diffract and recreat the original wavefront of the object, which appears three-dimensional to the viewer, so the hologram display a 3D image that can be viewed from different angles.
What parts do a 3D hologram includes?
A 3D hologram fan typically includes several key components that work together to create the illusion of a three-dimensional image.
LED Lights
These are used to project images. The fan usually has multiple LED lights that can change colors and brightness to enhance the visual effect. The main LED lamps we use is SMD lamps, with the technics of the SMT manufacture into fan blades.
Fan Blades
The fan blades rotate rapidly to create a surface on which the images are displayed. As the blades spin, they create a persistent image due to the persistence of vision effect.
Motor
motor is a critical component that enables the creation of captivating and dynamic holographic displays in a 3D hologram fan. The motor drives the rotation of the fan blades at high speeds. This rapid movement is crucial for creating the illusion of a continuous 3D image through the persistence of vision effect. The motor's operation is synchronized with the LED lights that project images. This synchronization ensures that the images are displayed correctly and appear coherent to the viewer. By controlling the speed and direction of the motor, the hologram fan can produce dynamic visuals, allowing for animations and interactive displays that enhance the overall experience. A well-functioning motor ensures smooth and stable rotation of the fan blades, which is important for maintaining the quality of the holographic image. Irregularities in rotation can lead to flickering or distortion.
Control System
This includes a microcontroller or processor that manages the operation of the fan, including the speed of rotation and the timing of the LED lights to create the desired images. For the jointed 3D hologram fans, a router is also neccessary to help the wireless device to control the whole unit screen.
Software
The software is used to design and upload the images or animations that will be displayed. It allows users to customize the content shown by the hologram fan. Now with the strengthening of software capabilities, more and more functions are presented in software, and the operation is easier and easier. Some model of 3D hologram device reaches one-button-play.
Housing/Frame
The structure that holds all the components together, providing stability and support for the fan and the LED system. There are two parts of frame structure. One is used to fix the 3D hologram fans into the frame structure, and the other is to fix the fans together into on unit. The solo hologram fans has a simple and easy handed frame bracket. There are two installation method of the frames, one is hanging up on the wall or ceiling, and the other is standing up on the floor.
Power Supply
This provides the necessary electrical power to operate the fan and the LED lights. To assemble a 3D hologram wall, quantities of power suppliers are needed. And some of the desktop 3D hologram fans needs to battery to reach the funtion of wireless application.
Cover (Optional)
As with any electrical device, it's important to ensure that the hologram fan is used according to the manufacturer's instructions. This includes using the correct power supply and avoiding exposure to water or moisture. And the rotating blades of the fan can pose a risk of injury if touched while in operation. It's advisable to keep hands and objects away from the spinning blades to prevent accidents. So a cover to the surface of a 3D hologram fan is neccessory if the device is installed too close to human. Customer can use acrylic covers or glass covers in the local place. And the manufacturer may supply covers for solo fans or small size fans.
These components work together to create a dynamic 3D visual effect that can be viewed from different angles, making it appear as if the images are floating in mid-air.
What is the parameters of 3D hologram fan?
The parameters of a 3D hologram fan
can vary depending on the specific model and manufacturer, but here are some common parameters to consider:
-
Size: The dimensions of the fan, including the diameter of the blades and the overall height of the unit.
- Weight: The total weight of the hologram fan, which can affect portability and installation.
- Power Supply: The voltage and wattage requirements for the fan, typically specified in volts (V) and watts (W).
- LED Specifications: The type and number of LEDs used, including their brightness (measured in lumens) and color capabilities (RGB or single color).
- Rotation Speed: The speed at which the fan blades rotate, usually measured in revolutions per minute (RPM).
- Image Resolution: The quality of the images displayed, often measured in pixels (e.g., 640x480, 800x600).
- Viewing Angle: The angle from which the holographic image can be viewed clearly, which can affect the overall experience.
- Control Interface: The type of control system used, such as remote control, app-based control, or manual buttons.
- Operating Temperature: The range of temperatures within which the fan can operate safely.
- Material: The materials used in the construction of the fan, which can affect durability and aesthetics.
These parameters can help users assess the suitability of a 3D hologram fan for their specific needs and applications.
The most important parameter of a 3D hologram fan
can vary depending on the intended use and specific requirements of the user, but generally, the following parameters are often considered the most critical:
Image Resolution: This is crucial because it determines the clarity and quality of the holographic images displayed. Higher resolution allows for more detailed and visually appealing images.
Rotation Speed: The speed at which the fan blades rotate is essential for creating a smooth and stable holographic effect. If the rotation speed is too slow, the images may appear flickering or unstable.
LED Brightness: The brightness of the LEDs affects how well the holographic images can be seen in different lighting conditions. Higher brightness is typically better for visibility.
Viewing Angle: A wider viewing angle allows more people to see the holographic display clearly from different positions, which is particularly important in public displays or presentations.
Control Interface: The ease of use of the control system can significantly impact user experience, especially if the fan is used in dynamic or interactive settings.
While all parameters are important, focusing on image resolution, rotation speed, and LED brightness is often key to achieving a high-quality holographic display.
How to distinguish the product good or not from the parameter?
To distinguish whether a 3D hologram fan is a good product based on its parameters, consider the following guidelines:
Image Resolution:
Look for higher resolution specifications (e.g., 800x600 pixels or better). Higher resolution typically means clearer and more detailed images.
Check for sample images or videos from the manufacturer to assess image quality.
Rotation Speed:
A higher RPM (revolutions per minute) is generally better, as it contributes to smoother image display. Look for fans with speeds around 600 RPM or higher.
Read reviews to see if users report any flickering or instability in the images.
