Description

A system for controlling LED light strings or display patterns using a smartphone Technical Field

[0001] The present invention relates to light string control, and in particular to a system for controlling LED light strings or display screen patterns with a smart phone. Background Art

[0002] Existing wireless remote control technology for controlling light-emitting diode (LED) decorative light strings or displays can only transmit color change instructions corresponding to a pattern pre-programmed in a smartphone application (app) via wireless transmission, including Wi-Fi or Bluetooth, to the light string or display controller, which has memory. The microcontroller unit (MCU) in the LED light string or display controller then drives each light point to achieve a default fixed or dynamic pattern. This pattern change is limited to the graphic editing function of the smartphone app, which can only play a limited number of default fixed or dynamic pattern variations, making it difficult to increase the richness and diversity of patterns.

Modes for Carrying Out the Invention

[0039] The working process of this specific embodiment includes the following steps: 1) Connecting the controlled light string to the LED light string control device, which includes an MCU equipped with a memory for storing color data and a processor. The MCU processor includes a Wi-Fi or Bluetooth signal receiving module, a control module, and a driver module. The appropriate power supply is selected based on the power consumption of the controlled unit; 2) Scanning the QR code on an Apple smartphone to download the dedicated app. After the download is complete, ensure that a wireless connection is established with the LED light string control device of the controlled light string; 3) According to the set operating instructions, select a pattern from the preset pattern list on the Apple smartphone screen, edit it, and then store it in the Apple smartphone's flash memory. For example, select the straight stripe pattern in the second column and second row of the pattern list as shown in Figure 2. Corresponding to the Apple smartphone being placed in a vertical 90° direction, the controlled light string displays "|". If the Apple smartphone is swung to the left, its built-in sensor will transmit the change parameters of the X, Y, and Z axes relative to the ground to the controlled LED light string control device, and the pattern will be rotated accordingly according to the rotation angle in real time. As shown in Figure 3, the controlled light string displays "45° / ". Continue to rotate the Apple smartphone to the left by an angle exceeding 45°, and the controlled light string displays ">45° / " as shown in Figure 4. 4) According to the instructions of the App, use the screen touch function to gradually select the desired pattern, edit the pattern, color, light brightness, color change speed, display time and other parameters, and store them in the Apple smartphone's flash memory to achieve the target pattern. 5) Entering the screen rotation mode of the Apple smartphone, the pattern displayed on the controlled end is rotated or moved by the user holding the Apple smartphone to a set angle. The generated X, Y, and Z axis signals correspond to the changes in the display graphics playback corresponding to the angle.
