Description

Technical Field

[0001] The present invention relates to a lighting device, particularly a multi-channel lighting control system and a control method thereof.

Background Art

[0002] Pulse Width Modulation (PWM) dimming technology adjusts brightness by changing the on-time and off-time of light-emitting diodes (LEDs). A general lighting system usually uses two pulse width modulation control channels, one for brightness control and the other for color temperature control. Since the above control system can achieve high efficiency, it is widely used in various lighting systems. However, when multi-channel pulse width modulation dimming control is required (for example, 10 channels of pulses, 100 channels, etc.), the above control system cannot effectively control each channel. Conventional solutions mainly rely on a large number of high-speed Field Programmable Gate Arrays (FPGAs) or high-speed Central Processing Units (CPUs) to achieve multi-channel pulse width modulation dimming control, but the above solutions result in a significant increase in cost.

[0018] Figure 1 is a block diagram of a multi-channel lighting control system according to one embodiment of the present invention. As shown in the figure, the multi-channel lighting control system 1 includes a control module 11 and a plurality of dimming modules 12. Each dimming module 12 includes a data latch 121, an input pin D1, an output pin D2, and a dimming pin D3. The control module 11 is connected to one dimming module 12, and the plurality of dimming modules 12 are interconnected. The number of the plurality of dimming modules 12 may be 256. In another embodiment, the number of the plurality of dimming modules 12 may be 100 and can be adjusted as needed. In this embodiment, the control module 11 may be a central processing unit (CPU). In another embodiment, the control module 11 may be a microcontroller (MCU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other similar component. In this example, the dimming module 12 may be a microcontroller (MCU). In another embodiment, the dimming module 12 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other similar component.

[0019] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention. Equivalent modifications or changes made based on the multi-channel lighting control system 1 of this embodiment should still be included in the protection scope of the present invention.

[0020] FIG. 2 and FIG. 3 are the first explanatory diagram and the second explanatory diagram of the operating state of the multi-channel lighting control system according to an embodiment of the present invention. As shown in FIG. 2, the plurality of dimming modules 12 are respectively connected to the plurality of lighting devices LD, and each dimming module 12 corresponds to one lighting device LD. The lighting device LD may be a light emitting diode (LED) lighting device. In another embodiment, the lighting device LD may be a fluorescent lamp, an incandescent lamp, or the like.

[0021] The control module 11 generates a multi-level control signal Ms. The multi-level control signal Ms includes a plurality of control signal data arranged in a preset order. In this embodiment, since the multi-level control signal Ms is 2048 bits, each control signal data is 8 bits. In another embodiment, the multi-level control signal Ms is 1600 bits, and each control signal data is 16 bits. The above is only an example, and the multi-level control signal Ms and the control signal data can be changed according to actual needs.

[0022] The multiple dimming modules 12 described above each correspond to multiple control signal data and are arranged in the preset order described above. Each dimming module 12 receives a multilevel control signal Ms and performs signal extraction, extracting the first of the multiple control signal data of the multilevel control signal Ms. In this embodiment, the number of multiple dimming modules 12 described above may be 256, corresponding to 256 dimming channels. The multilevel control signal Ms is 2048 bits and contains 256 control signal data, each control signal data being 8 bits. That is, the first dimming module 12 receives the multilevel control signal Ms (2048 bits) via input pin D1, extracts the first control signal data (8 bits) of the multilevel control signal Ms, and transmits the multilevel control signal Ms (2040 bits) to the second dimming module 12 via output pin D2. The second dimming module 12 receives a multilevel control signal Ms (2040 bits) via input pin D1, extracts the first control signal data (8 bits) of the multilevel control signal Ms, and transmits the multilevel control signal Ms (2032 bits) to the third dimming module 12 via output pin D2. The above control signal data is the second control signal data (8 bits) of the initial multilevel control signal Ms. The third dimming module 12 receives a multilevel control signal Ms (2032 bits) via input pin D1, extracts the first control signal data (8 bits) of the multilevel control signal Ms, and transmits the multilevel control signal Ms (2048 bits) to the fourth dimming module 12 via output pin D2. The above control signal data is the third control signal data (8 bits) of the initial multilevel control signal Ms (2048 bits). Similarly, the Nth dimming module 12 receives the multilevel control signal Ms via input pin D1, extracts the first control signal data (8 bits) of the multilevel control signal Ms, and transmits the multilevel control signal Ms to the N+1th dimming module 12 via output pin D2. The above control signal data is the Nth control signal data (8 bits) of the initial multilevel control signal Ms (2048 bits).The last (256th) dimming module 12 receives the multi-level control signal Ms via the input pin D1 and extracts the first control signal data (8 bits) of the multi-level control signal Ms. The above control signal data is the last (256th) control signal data (8 bits) of the initial multi-level control signal Ms. Each dimming module 12 stores the extracted control signal data in its data latch 121.

[0023] As shown in FIG. 3, the control module 11 generates the multi-level control signal Ms and generates the reset signal Rs after a preset time. Then, after each dimming module 12 receives the reset signal Rs, it converts the extracted control signal data into the dimming signal Ps and outputs the dimming signal Ps to the corresponding lighting device LD via the dimming pin D3 to perform dimming control. Then, the dimming module 12 transmits the reset signal Rs to the next dimming module 12. Finally, after receiving the reset signal, each dimming module 12 receives the reset program and waits for the next multi-level control signal Ms.

[0024] As can be seen from the above, in this embodiment, the multi-channel lighting control system 1 includes a control module 11 and a plurality of dimming modules 12. The control module 11 generates the multi-level control signal Ms. The multi-level control signal Ms includes a plurality of control signal data arranged in a preset order. The plurality of dimming modules 12 respectively correspond to the plurality of control signal data and are arranged in the above preset order. After each dimming module 12 receives the multi-level control signal Ms, it performs signal extraction and extracts the first one of the above plurality of control signal data of the multi-level control signal Ms. Each dimming module 12 converts the extracted control signal data into the dimming signal Ps and outputs the dimming signal Ps to the corresponding lighting device LD. Due to the signal extraction mechanism and circuit design based on the above special preset order, the multi-channel lighting control system 1 realizes multi-channel pulse width modulation dimming control of 256 levels or more. Therefore, the multi-channel lighting control system 1 can meet the requirements of actual applications.

[0025] In this embodiment, each dimming module 12 stores the extracted control signal data in a data latch 121. The control module 11 generates a multi-level control signal Ms and a reset signal Rs after a preset time. After receiving the reset signal, each dimming module 12 converts the extracted control signal data into a dimming signal Ps and outputs the dimming signal Ps to the corresponding lighting device LD. Next, the dimming module 12 executes a reset program and waits for the next multi-level control signal Ms. With the data latch mechanism and reset mechanism described above, the multi-channel lighting control system 1 can achieve 256-level or more multi-channel pulse width modulation dimming control via the control module 11 and the multiple dimming modules 12 described above, without requiring the use of numerous high-speed field-programmable gate arrays (FPGAs) or high-speed central processing units (CPUs). Therefore, the cost of the multi-channel lighting control system 1 can be significantly reduced. In this way, the applications of the multi-channel lighting control system 1 can be broadened and the requirements of different applications can be met.

[0026] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the multi-channel lighting control system 1 of this embodiment should still be within the scope of protection of the present invention.

After receiving the multi-level control signal, each dimming module performs signal extraction to extract the first of the multi-level control signal data. Each dimming module converts the extracted control signal data into a dimming signal and outputs the dimming signal to the corresponding lighting device. Through the signal extraction mechanism and circuit design based on the above special preset order, the multi-channel lighting control system can achieve multi-channel pulse-width modulation dimming control of 256 levels or more. Therefore, the multi-channel lighting control system can meet the needs of actual applications.

[0028] Furthermore, according to an embodiment of the present invention, each dimming module stores the extracted control signal data in a data latch. The control module generates a multi-level control signal and generates a reset signal after a preset time has elapsed. After receiving the reset signal, each dimming module converts the extracted control signal data into a dimming signal and outputs it to the corresponding lighting device. Next, the dimming module executes a reset program and waits for the next multi-level control signal. With the above data latch mechanism and reset mechanism, the multi-channel lighting control system can achieve 256-level or more multi-channel pulse width modulation dimming control via the control module and the above-mentioned multiple dimming modules, and does not require the use of a large number of high-speed field-programmable gate arrays (FPGAs) or high-speed central processing units (CPUs). Therefore, the cost of the multi-channel lighting control system can be significantly reduced.
