Technical Field
[0001] This utility model relates to LED lighting fixtures, and specifically discloses a high-voltage color LED light strip with multi-mode control. Background Technology
[0002] High-voltage colored LED light strips refer to light strips that connect directly to AC mains power by connecting multiple LED beads in series to form a 220V operating module. Early colored LED light strips could only change the color of the light as a whole, not in segments, resulting in a limited lighting effect. In recent years, the industry has developed high-voltage colored LED light strips that can change the color in segments, also known as high-voltage RGB LED light strips. However, these use an external controller to directly control the current of each light module, resulting in numerous electronic components, complex circuitry, high cost, and inconvenience in use. Utility Model Content
[0003] Therefore, it is necessary to address the existing technical problems by providing a high-voltage color LED light strip with fewer electronic components, simpler circuitry, lower manufacturing costs, and easier use, featuring multi-mode control.
[0004] To address the problems of existing technologies, this utility model discloses a multi-mode controlled high-voltage color LED light strip, including a circuit board. The circuit board has multiple light-emitting modules, each with a working voltage equal to that of the mains power, connected in series by LED beads of different colors. The circuit includes a neutral wire circuit, a live wire circuit, and multiple control units connected in parallel to the neutral and live wire circuits. Each control unit includes a rectifier module, a first control module, and a second control module.

The control output terminal of the first control module is connected to the signal input terminal of the second control module. The output terminal of the second control module controls the multiple light-emitting modules respectively. The signal output terminals and signal input terminals of the multiple control units are connected in series sequentially, wherein the signal input terminal of the first control unit is used to connect to an external controller.

Furthermore, the light-emitting modules between multiple control units can be independently controlled and interact with each other to achieve flowing water, color-changing, and other lighting effects. Also, since the working voltage of the light-emitting modules is the same as that of the mains power, they can be directly connected to the mains power, making them convenient to use.

[0015] refer to Figure 2 The circuit of the multi-mode controlled high-voltage colored LED light strip includes a neutral wire circuit N, a live wire circuit L, and multiple control units connected in parallel to the neutral wire circuit N and the live wire circuit L. The multiple control units are arranged along the length of the LED light strip. Each control unit includes a rectifier module 60, a first control module 61, a second control module 62, a red light module R, a green light module G, and a blue light module B. The first control module 61 stores the control program, sends control commands, and detects signals from an external controller. The second control module 62 receives, transmits, and executes control commands, directly controlling the three light-emitting modules. The red light module R, the green light module G, and the blue light module B are each composed of multiple LED beads of the corresponding light-emitting color connected in series, and the operating voltage of each light-emitting module is 220V, the same as the mains voltage.
[0016] The rectifier module 60 includes a surface-mount bridge rectifier DB. The input terminal of the surface-mount bridge rectifier DB is connected to the neutral wire circuit N and the live wire circuit L. Its output terminal includes a positive power supply terminal V+ and a negative power supply terminal V-. A first resistor R1, which acts as a voltage divider, is connected to the positive power supply terminal V+. The positive power supply terminal V+ outputs a 220V voltage equal to the mains voltage. After being divided by the first resistor R1, a 5V voltage is output after the first resistor R1.
[0017] The first control module 61 includes a microcontroller U1, which has a positive terminal VCC, a negative terminal GND, a zero-crossing detection terminal ID4, and control signal output terminals ID1 to ID3. The positive terminal VCC is connected to the first resistor R1 and, through a parallel connection of a second resistor R2, a first capacitor C1, and a first diode D1, is connected to the negative terminal V- of the power supply. The negative terminal GND is also connected to the negative terminal V-. The zero-crossing detection terminal ID4 is connected to the negative terminal V- through a parallel connection of a third resistor R3 and a second capacitor C2, and, through a fourth resistor R4, is connected to one input terminal of the surface-mount bridge rectifier DB. The zero-crossing detection terminal ID4 synchronizes multiple control units by detecting the charging and discharging of the second capacitor C2. The control signal output terminals ID1 to ID3 are used to output control signals and detect whether external control commands have been received.
[0018] The second control module 62 includes a control chip U2, which includes a positive terminal VDD, a negative terminal GND, a red light control pin OUTR, a green light control pin OUTG, a blue light control pin OUTB, a signal input pin DI, and a signal output pin DO. The positive terminal VDD is connected to the first resistor R1, and the negative terminal GND is connected to the negative power supply V-. The red light control pin OUTR, green light control pin OUTG, and blue light control pin OUTB are connected to the emitters of the first transistor Q1, the second transistor Q2, and the third transistor Q3, respectively. The bases of the first transistor Q1, the second transistor Q2, and the third transistor Q3 are connected to the rear end of the first resistor R1 through the fifth resistor R5, the sixth resistor R6, and the seventh resistor R7, respectively. The collectors of the first transistor Q1, the second transistor Q2, and the third transistor Q3 are connected to the negative terminals of the red light module R, the green light module G, and the blue light module B, respectively. The positive terminals of the red light module R, the green light module G, and the blue light module B are connected to the positive terminal V+ of the power supply. The signal input pin DI is connected to the control signal output pins ID1 to ID3 of the microcontroller 1. The signal output pin DO is connected to the signal input / output pin DI of the next control unit. A clamping circuit PN composed of two diodes is provided on the signal input pin DI and the signal output pin DO. The clamping circuit PN can provide clamping protection for the signal output voltage. The signal output and signal input pins of the control chip U2, which controls multiple control units on the LED light strip, are connected in series. That is, the signal output pin DO of the control chip U2 of the previous control unit is connected to the signal input pin DI of the control chip of the next control unit. The signal input pin of the control chip U2 of the control unit at the beginning of the LED light strip, i.e. the first control unit, is used to connect to an external controller.
[0019] The working principle of this utility model is as follows: The rectifier module converts AC mains power into 220V high-voltage DC power to power the three light-emitting modules. After voltage division by the first resistor R1, it outputs 5V voltage to power the microcontroller U1 and the control chip U2. When the first control module 61 of the first control unit at the beginning of the LED strip, i.e., the control signal output terminals D1 to D3 of the first microcontroller U1, detects a control command from an external controller, it stops working and enters external control mode. The external controller transmits the command to the control chip U2 in the control unit, and then sequentially to the control chip U2 of the last control unit. When the microcontroller U1 at the beginning of the LED strip does not detect an external controller, it enters internal control mode. The microcontroller U1 calls the internal control program, which transmits the command to the control chip U2 in that control unit, and then sequentially to the control chip U2 of the last control unit. Alternatively, the microcontroller U1 in each control unit individually controls its control chip U2. The microcontrollers U1 of each control unit work synchronously through the zero-crossing detection pin.
[0020] This invention comprises multiple control units, each including a first control module and a second control module. The first control module stores control commands, while the second control module controls multiple light-emitting modules within that control unit. The second control module can receive control commands from the first control module to enter an internal control mode, eliminating the need for an external controller, thus offering convenience and low operating costs. Alternatively, it can receive control commands from an external controller to enter an external control mode, enabling more complex and diverse lighting effects. Therefore, this invention offers advantages such as diverse control modes, fewer electronic components in the circuit, and simple wiring. Furthermore, the light-emitting modules within the multiple control units can be independently controlled and interact with each other to achieve lighting effects such as flowing water and color-changing effects. Additionally, since the operating voltage of the light-emitting modules is the same as that of mains power, they can be directly connected to mains power, making them convenient to use.
[0021] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
