Description

Technical Field

[0001] This utility model relates to the field of decorative arts, specifically a compact LED decorative structure. Background Technology

[0002] LED ornaments are widely used in the decoration field, but existing products are mostly static lights or simple flashing modes, lacking realistic dynamic fluid light effects, and cannot meet consumers' demand for highly interactive and realistic decorative effects.

[0003] To achieve fluid simulation display, an LED array with a resolution of at least 16×16 (256 LEDs) is required. However, existing driving solutions have obvious drawbacks: either a bulky dedicated LED controller is used, or more than 32 current-limiting resistors are required. Both result in a large product size and high power consumption, making it difficult to integrate into the jewelry casing. Furthermore, excessive power consumption can shorten battery life and affect wearing comfort. Utility Model Content

[0004] The purpose of this invention is to provide a compact LED jewelry structure to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A compact LED jewelry structure, comprising:

[0007] The outer shell has through slots on the periphery and an open structure at the top.

[0008] The battery is installed in the casing;

[0009] The control circuit board installed in the housing integrates an LED array, an MCU, an accelerometer, a step-down chip, and a USB interface aligned with the slot. The step-down chip is electrically connected to the battery to provide power. The positive and negative terminals of each LED in the LED array are directly wired to the IO port of the MCU.

[0010] And a window piece that is fixedly installed at the opening of the outer casing.

[0011] Furthermore, the MCU controls the switching on and off of the LEDs in the LED array via a high-speed switching method to prevent them from burning out due to overcurrent.

[0012] Furthermore, the accelerometer is used to collect XYZ three-axis acceleration signals of the jewelry and transmit them to the MCU. The MCU controls the LED array to light up or turn off based on the acceleration signals using a grid calculation method to generate fluid light effects.

[0013] Furthermore, the control circuit board is a single PCB board, with the MCU, accelerometer and buck chip integrated on the same surface of the PCB board, and the LED array integrated on another surface.

[0014] Furthermore, the edge of the window panel is fixed to the inner wall of the outer casing by snap-fit ​​or adhesive.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model adopts a design that directly connects the LED array to the MCU's I / O port with wires, eliminating the need for additional current-limiting resistors and dedicated controllers; at the same time, it integrates the LED array, MCU, accelerometer, and step-down chip onto the control circuit board, significantly reducing the overall structural volume and achieving compact integration of the jewelry; furthermore, the direct connection design between the LED and the MCU avoids the energy loss caused by resistive voltage division; and the high-speed switching mode of the MCU controls the LED, making the average current of a single LED much lower than the rated power consumption, thereby achieving the effect of low average power consumption under typical system operating mode and effectively extending the battery life.

[0017] 2. This utility model collects the XYZ three-axis acceleration signals of the jewelry through an accelerometer, and combines them with the grid calculation method of the MCU to drive the LED array to generate a flowing light effect that is close to that of real liquid. Moreover, the light effect can be adjusted in real time according to the wearer's movements, which significantly enhances the visual realism and interactivity of the jewelry and meets consumers' demand for high-quality decorative effects.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-4 In this embodiment of the invention, a compact LED jewelry structure includes:

[0027] The outer shell 4 has a through slot on the outside and an open structure at the top;

[0028] Battery 3 is installed in casing 4;

[0029] The control circuit board 2, installed in the housing 4, integrates an LED array 7, an MCU 6, an accelerometer 5, a step-down chip, and a USB interface aligned with the slot. The step-down chip is electrically connected to the battery 3 for power supply. The positive and negative terminals of each LED in the LED array 7 are directly connected to the I / O ports of the MCU 6. This connection method allows the MCU 6 to control N*(N-1) LEDs with N pins (for example, up to 272 LEDs can be controlled with 17 pins, meeting the control requirement of 256 LEDs at a 16x16 resolution), without the need for additional resistors or dedicated controllers. Since there are no additional chips or resistors in the circuit, the energy consumed by directly connecting the LEDs is significantly reduced compared to conventional resistor current limiting.

[0030] And a window piece 1 that is fixedly installed at the opening position of the outer casing 4.

[0031] The MCU6 controls the LEDs in the LED array 7 to turn on and off using a high-speed switching method to prevent them from burning out due to overcurrent. Specifically, taking advantage of the high-speed switching capability of LEDs, each LED is cyclically turned on for 100µs and turned off for 21.5ms. Although the current on the LED is 25mA each time it is turned on, the average current is only 0.116mA, which is far below the rated power consumption of the LED.

[0032] Among them, the control circuit board 2 is a single PCB board, the MCU6, accelerometer 5 and buck chip are integrated on the same surface of the PCB board, and the LED array 7 is integrated on another surface.

[0033] The edge of the window piece 1 is fixed to the inner wall of the outer shell 4 by snap-fit ​​or adhesive.

[0034] Therefore, compared with existing LED driving solutions, this utility model adopts a design that directly connects the LED array 7 and the IO port of the MCU6 with wires, eliminating the need for additional current limiting resistors and dedicated controllers; at the same time, the MCU6, accelerometer 5, and step-down chip are integrated on the same surface of the control circuit board 2, and the LED array 7 is integrated on another surface. Combined with the slot structure of the outer shell 4 and the fixing method of the window piece 1, the overall structural volume is greatly reduced, achieving compact integration of the jewelry.

[0035] Furthermore, the direct connection design between the LED and MCU6 avoids the energy loss caused by resistor voltage division; at the same time, the high-speed switching mode of MCU6 controls the LED, making the average current of a single LED much lower than the rated power consumption, thereby achieving the effect of low average power consumption in the typical operating mode of the system and effectively extending the battery life.

[0036] Example 2: Based on Example 1, accelerometer 5 is used to collect the XYZ three-axis acceleration signals of the jewelry and transmit them to MCU6. MCU6 controls the LED array 7 to light up or turn off based on the acceleration signals through grid calculation method to generate fluid light effect.

[0037] Specifically, the MCU6 employs a grid-based computing method, dividing the computational grid according to the LEDs (for example, a 16x16 LED array is divided into 16x16 computational grids). Simultaneously, 256 particles are introduced as a liquid simulation carrier. In each calculation cycle, acceleration signals are directly applied to the particles to calculate their velocity and displacement, while simultaneously solving for physical states such as particle collisions. Finally, the number of particles in the grid is analyzed. When the number of particles in the grid is not zero, the corresponding LED is marked as lit; otherwise, it is marked as off. The LED control function sequentially lights the corresponding LEDs according to the calculated markings.

[0038] Therefore, compared with existing LED jewelry, this utility model uses an accelerometer 5 to collect the XYZ three-axis acceleration signals of the jewelry, and combines the grid calculation method of the MCU 6 to drive the LED array 7 to generate a flowing light effect that is close to that of real liquid. Moreover, the light effect can be adjusted in real time according to the wearer's movements, which significantly enhances the visual realism and interactivity of the jewelry and meets consumers' demand for high-quality decorative effects.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
