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 obtain 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 cost of the above solutions increases significantly.

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 connected to each other. The number of the plurality of dimming modules 12 may be 256. In another embodiment, the number of the plurality of dimming modules 12 described above may be 100, and can be adjusted according to actual needs. 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 members. 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 members.

[0019] Of course, this embodiment is only used for illustrative explanation 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 above-mentioned plurality of dimming modules 12 respectively correspond to a plurality of control signal data and are arranged in the preset order described above. After receiving the multi-level control signal Ms, each dimming module 12 performs signal extraction and extracts the first of the plurality of control signal data of the multi-level control signal Ms. In this embodiment, the number of the above-mentioned plurality of dimming modules 12 may be 256, corresponding to 256 dimming channels. The multi-level control signal Ms is 2048 bits, includes 256 control signal data, and each control signal data is 8 bits. That is, the first dimming module 12 receives the multi-level control signal Ms (2048 bits) via the input pin D1, extracts the first control signal data (8 bits) of the multi-level control signal Ms, and transmits the multi-level control signal Ms (2040 bits) to the second dimming module 12 via the output pin D2. The second dimming module 12 receives the multi-level control signal Ms (2040 bits) via the input pin D1, extracts the first control signal data (8 bits) of the multi-level control signal Ms, and transmits the multi-level control signal Ms (2032 bits) to the third dimming module 12 via the output pin D2. The above control signal data is the second control signal data (8 bits) of the initial multi-level control signal Ms. The third dimming module 12 receives the multi-level control signal Ms (2032 bits) via the input pin D1, extracts the first control signal data (8 bits) of the multi-level control signal Ms, and transmits the multi-level control signal Ms (2048 bits) to the fourth dimming module 12 via the output pin D2. The above control signal data is the third control signal data (8 bits) of the initial multi-level control signal Ms (2048 bits). Similarly, the Nth dimming module 12 receives the multi-level control signal Ms via the input pin D1, extracts the first control signal data (8 bits) of the multi-level control signal Ms, and transmits the multi-level control signal Ms to the (N + 1)th dimming module 12 via the output pin D2. The above control signal data is the Nth control signal data (8 bits) of the initial multi-level 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 a multi-level control signal Ms and generates a reset signal Rs after a preset time. Thereafter, after each dimming module 12 receives the reset signal Rs, it converts the extracted control signal data into a dimming signal Ps and outputs the dimming signal Ps to the corresponding lighting device LD via the dimming pin D3 to perform dimming control. Thereafter, 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 a 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 a 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 of the plurality of control signal data of the multi-level control signal Ms. 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. With 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] Also, in this embodiment, each dimming module 12 stores the extracted control signal data in the data latch 121. The control module 11 generates a multi-level control signal Ms and generates 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 above-described data latch mechanism and reset mechanism, the multi-channel lighting control system 1 can achieve multi-channel pulse width modulation dimming control of 256 levels or more via the control module 11 and the above-described plurality of dimming modules 12, and there is no need to employ 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 1 can be significantly reduced. In this way, the application of the multi-channel lighting control system 1 can be made wider, and the requirements of different applications can be satisfied.

[0026] 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.

[0027] In a conventional control system, multi-channel pulse-width modulation dimming control cannot be achieved. Conventional solutions rely on a large number of high-speed field-programmable gate arrays (FPGAs) or high-speed central processing units (CPUs) to implement multi-channel pulse-width modulation dimming control, but the cost significantly increases in the above solutions. In contrast, according to an embodiment of the present invention, a multi-channel lighting control system includes a control module and a plurality of dimming modules. The control module generates a multi-level control signal including a plurality of control signal data arranged in a preset order. The plurality of dimming modules respectively correspond to the plurality of control signal data and are arranged in a preset order. After each dimming module receives the multi-level control signal, it performs signal extraction to extract the first of the multi-level control signal data of the multi-level control signal. Each dimming module converts the extracted control signal data into a dimming signal and outputs the dimming signal to the corresponding lighting device. Based on the above special preset-order-based signal extraction mechanism and circuit design, 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 requirements of actual applications.

[0028] Also, according to an embodiment of the present invention, the control signal data extracted by each dimming module is stored 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 each dimming module receives the reset signal, it 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 to wait for the next multi-level control signal. With the above data latch mechanism and reset mechanism, the multi-channel lighting control system can achieve multi-channel pulse-width modulation dimming control of 256 levels or more through the control module and the above plurality of dimming modules, and there is no need to employ 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.

[0029] Also, according to an embodiment of the present invention, the multi-channel lighting control system realizes multi-channel pulse width modulation dimming control of 256 levels or more through a signal extraction mechanism and circuit design based on a special preset order. Therefore, the application of the multi-channel lighting control system can be made wider, and the requirements of different applications can be satisfied.

[0030] Also, according to an embodiment of the present invention, the multi-channel lighting control system can be applied to a light-emitting diode lighting device that is highly efficient and suitable for environmental protection, and realizes multi-channel pulse width modulation dimming control. Therefore, the multi-channel lighting control system can realize various different intelligent applications and conform to the trend of future development.

[0031] Furthermore, according to an embodiment of the present invention, since the design of the multi-channel lighting control system is simple, the desired effect can be obtained while suppressing the cost. Therefore, the multi-channel lighting control system can realize higher practicability and satisfy the requirements of different applications. From the above, it can be seen that the multi-channel lighting control system based on the embodiment of the present invention can surely achieve excellent technical effects.
