Description

Technical Field

[0001] This invention relates to the field of power control technology, specifically a power control scheme. Background Technology

[0002] Due to its advantages such as energy saving, environmental friendliness, long lifespan, and ease of control, LED lighting is widely used in various fields, with its application in plant lighting being particularly prominent. In existing technologies, in outdoor plant farms, LED lighting is used to increase light intensity and extend light exposure time so that plants can grow quickly and efficiently under conditions of insufficient sunlight or at night. Alternatively, in some indoor plant factories, LED lighting is used to replace other lighting methods to improve luminous efficiency. In these applications, applying LED lighting to plant growth can improve the quality of agricultural products, increase yields, and shorten production cycles. With the development of large-scale LED agriculture, increasingly higher demands are being placed on both overall and individual lighting control.

[0003] Currently, LED lighting fixtures either require unified control or can only be controlled individually, making it difficult to flexibly adjust to the needs of the planting site. When controlling the power supply, they rely on control modules for command transmission, which results in long delays in analysis and execution. They cannot achieve self-switching within the same circuit, leading to low portability and hindering the development of LED planting industry. Furthermore, they cannot provide effective control over the power supply.

[0004] To address this, we developed a new power control solution. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a power control scheme that solves the problems of current LED lighting systems, which either require unified control or can only be controlled individually, making it difficult to flexibly adjust to the needs of the planting site. Furthermore, the current power control relies on a control module for command transmission, resulting in long analysis and execution delays, the inability to automatically switch within the same circuit, low portability, and negatively impacting the development of LED planting industry, ultimately failing to provide effective power control.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a power control scheme, comprising a group control signal, two adjustable power supplies and two controllers, wherein the output terminals of the two adjustable power supplies are respectively connected to the two controllers, the two controllers control the two adjustable power supplies individually, and the two controllers control the two adjustable power supplies in a group through an external group control signal.

[0009] The controller includes a controller A terminal and a controller B terminal. The controller A terminal consists of multiple ports that connect the controller to an adjustable power supply, and the controller B terminal is the external input port of the controller.

[0010] Preferably, the voltage range of both adjustable power supplies is 0-10V.

[0011] The above technical solution enables the two adjustable power supplies to stabilize the voltage at 10V through a linear voltage regulator circuit, thereby providing a stable output voltage within 10V. This allows for stable control of the output current of the adjustable power supplies, ensuring the accuracy of the control.

[0012] Preferably, the multiple ports of the controller A end are respectively an auxiliary power supply 12V interface, a dimming control terminal positive terminal DIM+, and a dimming control terminal negative terminal DIM-, which are connected to an adjustable power supply; the multiple ports of the controller B end are respectively an auxiliary power supply 12V interface, a dimming control terminal positive terminal DIM+, and a dimming control terminal negative terminal DIM-, which are connected to an external group control signal.

[0013] The above technical solution enables the controller to switch between individual control and group control through the connection between end A and end B. When the controller is controlled through end A, it is an independent control of the adjustable power supply. When the controller is controlled through end B, it is a group control for the external group control signal. The switching is seamless, with low latency and good performance.

[0014] Preferably, the controller further includes a linear voltage regulator U1, capacitors C1 and C2, resistors RS1, RS2, and RS3. The auxiliary power supply 12V interface of the controller A terminal is connected to the first terminal of capacitor C1, and the other terminal of capacitor C1 is connected to the negative terminal DIM- of the dimming control terminal of the controller A terminal. One end of resistor RS1 is connected to capacitor C1, and the other end of resistor RS1 is connected to U1. One end of resistor RS2 is connected to U1, and the other end is connected to one end of resistor RS1. One end of resistor RS3 is connected to one end of resistor RS1, and the other end is connected to one end of resistor RS2. One end of capacitor C2 is connected to one end of resistor RS3, and the other end is connected to one end of resistor RS2.

[0015] The above technical solution enables the linear voltage regulator circuit to provide continuous and stable voltage control for the adjustable power supply, thereby enabling subsequent resistance ratio adjustment.

[0016] Preferably, the controller further includes resistors R1-R10 for forming the upper and lower arms. Resistors R6-R10 are connected in parallel with capacitor C2. Resistor R1 is connected to resistor R6, resistor R2 is connected to resistor R7, resistor R3 is connected to resistor R8, resistor R4 is connected to resistor R9, and resistor R5 is connected to resistor R10.

[0017] The above technical solution enables multiple sets of corresponding upper and lower arms to be switched by adjusting the resistance value. It can be adjusted according to the actual lighting conditions required for planting to obtain the required proportional relationship, thereby achieving different lighting effects. The multi-level adjustment is simple to operate, has low delay, good portability, and a wide range of applications.

[0018] Preferably, the controller further includes switches SW0-SW6 for controlling R1-R10. One end of switch SW0 is connected to the positive terminal DIM+ of the dimming control terminal at controller A, and the other end is connected to the negative terminal DIM- of the dimming control terminal. Switch SW1 is connected to resistor R6, switch SW2 is connected to resistor R7, switch SW3 is connected to resistor R8, switch SW4 is connected to resistor R9, and switch SW5 is connected to resistor R10. One end of switch SW6 is connected to the positive terminal DIM+ of the dimming control terminal at controller A, and the other end of switch SW6 is connected to the negative terminal DIM- of the dimming control terminal at controller B.

[0019] Through the above technical solution, in the SW0 position, there are no upper and lower arm resistors, so DIM+ and DIM- are directly short-circuited, making their voltage 0V. At this time, the power output is 0, the LED is not lit, and the lamp enters the standby state. In the SW6 position, there are no upper and lower arm resistors, so the DIM+ terminal of A is directly connected to the DIM+ terminal of B. At this time, the A terminal of the power control terminal (12V port, DIM+ port, DIM- port) and the B terminal of the controller (12V port, DIM+ port, DIM- port) are short-circuited one-to-one. The power control port is transferred from the A terminal to the B terminal of the controller and receives the control of the signal input to the B terminal. When the toggle switch is moved away from SW6, the signal input to the B terminal is disconnected, and the power supply is once again controlled by the controller toggle switch. Different control effects are achieved by adjusting the position.

[0020] Preferably, each of SW1-SW5 is an individual adjustable switch, and different upper and lower arm resistances can be obtained by controlling different switches.

[0021] By adjusting the SW1-SW5 settings, different ratios of the upper and lower arms can be switched, thereby obtaining different lighting effects.

[0022] Preferably, U1 is located near the controller A.

[0023] Through the above technical solution, U1 enables the controller A terminal to perform independent and stable control of the adjustable power supply, achieving a better control effect. The linear voltage regulator circuit can provide a stable output voltage to the adjustable power supply, thereby facilitating the control of the output current of the adjustable power supply.

[0024] (III) Beneficial Effects

[0025] This invention provides a power control scheme. It has the following beneficial effects:

[0026] 1. This power control solution enables the control of individual lamps and groups of lamps under the same wiring. The switching control can be achieved simply by controlling and adjusting the switch at different levels, which improves the portability of use, achieves precise control of the adjustable power supply, and also achieves the effect of low delay when dimming at multiple levels through the knob.

[0027] 2. This power control scheme, through the setting of controllers and group control signals, enables individual control of adjustable power supplies via the controller, achieving precise control. It also allows for seamless switching and group control using external group control signals, ensuring effective performance and meeting the high-efficiency requirements of the LED planting industry.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example:

[0032] like Figures 1-2As shown, this embodiment of the invention provides a power control scheme, including a group control signal, two adjustable power supplies, and two controllers. The output terminals of the two adjustable power supplies are respectively connected to the two controllers. The two controllers control the two adjustable power supplies individually, and the two controllers also control the two adjustable power supplies as a group through an external group control signal. Each controller includes a controller A terminal and a controller B terminal. Controller A terminal has multiple ports for connecting the controller to the adjustable power supplies, and controller B terminal is an external input port for the controller. The voltage range of both adjustable power supplies is 0-10V. This allows the two adjustable power supplies to stabilize their voltage at 10V through a linear voltage regulator circuit, thereby providing a stable output voltage within 10V, thus controlling the power supply. The output current of the adjustable power supply forms a stable control, ensuring the accuracy of the control. Multiple ports on controller A are connected to the adjustable power supply (12V auxiliary power interface, dimming control positive DIM+, dimming control negative DIM-). Similarly, multiple ports on controller B are connected to external group control signals (12V auxiliary power interface, dimming control positive DIM+, dimming control negative DIM-). This allows the controller to switch between individual and group control via the connection between A and B. When the controller is controlled via A, it independently controls the adjustable power supply; when controlled via B, it performs group control using an external group control signal. This seamless switching results in low latency and excellent performance.

[0033] like Figure 2As shown, the controller also includes a linear voltage regulator U1, capacitors C1 and C2, resistors RS1, RS2, and RS3. U1 is positioned near terminal A of the controller, enabling terminal A to independently and stably control the adjustable power supply, achieving better control performance. The linear voltage regulator circuit provides a stable output voltage to the adjustable power supply, facilitating control of the output current. The auxiliary 12V power supply interface of terminal A is connected to the first terminal of capacitor C1, and the other terminal of capacitor C1 is connected to the negative DIM- port of the dimming control terminal of terminal A. One end of resistor RS1 is connected to capacitor C1, and the other end of resistor RS1 is connected to U1. One end of resistor RS2 is connected to U1, and the other end is connected to one end of resistor RS1. One end of resistor RS3 is connected to one end of resistor RS1, and the other end is connected to one end of resistor RS2. One end of capacitor C2 is connected to one end of resistor RS3, and the other end is connected to one end of resistor RS2. This allows the linear voltage regulator circuit to provide continuous and stable voltage control to the adjustable power supply, thereby enabling subsequent resistor ratio adjustment. The controller also includes resistors R1-R10 to form the upper and lower arms. Resistors R6-R10 are connected in parallel with capacitor C2. Resistor R1 is connected to resistor R6, resistor R2 is connected to resistor R7, resistor R3 is connected to resistor R8, and resistor R9 is connected to... A resistor R4 is connected, and a resistor R5 is connected to resistor R10; this allows multiple sets of corresponding upper and lower arms to be switched by adjusting the resistance value. This allows for adjustment based on the actual lighting requirements of the planting area, achieving the desired proportional relationship and thus obtaining different lighting effects. The multi-level adjustment is simple to operate, has low latency, good portability, and a wide range of applications. The controller also includes switches SW0-SW6 for controlling R1-R10. SW1-SW5 are all individually adjustable switches, allowing for different upper and lower arm resistances by controlling different switches. Adjusting SW1-SW5 allows switching between different upper and lower arm ratios, thereby obtaining different lighting effects. Switch SW0... One end of switch SW6 is connected to the positive terminal DIM+ of the dimming control terminal on controller A, and the other end is connected to the negative terminal DIM- of the dimming control terminal on controller B. Switch SW1 is connected to resistor R6, switch SW2 is connected to resistor R7, switch SW3 is connected to resistor R8, switch SW4 is connected to resistor R9, switch SW5 is connected to resistor R10, one end of switch SW6 is connected to the positive terminal DIM+ of the dimming control terminal on controller A, and the other end of switch SW6 is connected to the negative terminal DIM- of the dimming control terminal on controller B. In the SW0 position, there are no upper and lower arm resistors, so DIM+ and DIM- are directly short-circuited, making their voltage 0V. At this time, the power output is 0, the LED is not lit, and the lamp enters the standby state.In SW6 position, without upper and lower arm resistors, the DIM+ terminal of A is directly connected to the DIM+ terminal of B. At this time, the A terminals (12V port, DIM+ port, DIM- port) of the power control terminal and the B terminals (12V port, DIM+ port, DIM- port) of the controller are shorted one-to-one. The power supply control port shifts from A terminal to B terminal of the controller and receives control from the signal input at B terminal. When the toggle switch is turned off from SW6, the signal input at B terminal is disconnected, and the power supply is once again controlled by the controller toggle switch. Different control effects are achieved through gear adjustment.

[0034] Working Principle: The power supply voltage is stabilized at 10V through a linear step-down circuit. Then, by using a toggle switch to provide different upper and lower arm resistance ratios, a stable output voltage within 10V is provided, thus providing stable control over the power supply's output current. The linear voltage circuit consists of a linear step-down IC and its peripheral components (capacitors C1 and C2, resistors RS1, RS2, and RS3), modulating 12V to a stable 10V. SW1-SW5 positions: By using different positions on the toggle switch, the upper and lower arm ratios can be configured as R1:R6, R2:R7, R3:R8, R4:R9, R5:R10, etc. The voltage is then taken from the middle of the upper and lower arms and supplied to the DIM+ / DIM- terminals of the power supply to form the control. SW1-SW5 all contain upper and lower arm resistors, which can be adjusted according to actual needs. To determine the required percentage of illumination for planting, adjust the resistance values ​​of R1-R10 to obtain the desired ratio. In the SW0 setting, with no upper or lower arm resistors, DIM+ and DIM- are directly short-circuited to achieve a voltage of 0V. At this setting, the power output is 0, the LED is off, and the lamp enters standby mode. In the SW6 setting, with no upper or lower arm resistors, DIM+ at end A is directly connected to DIM+ at end B. In this setting, the A end of the power control terminal (12V port, DIM+ port, DIM- port) and the B end of the controller (12V port, DIM+ port, DIM- port) are short-circuited one-to-one. The power control port shifts from end A to end B of the controller and receives control from the signal input at end B. When the toggle switch is turned away from SW6, the signal input at end B is disconnected, and the power supply is once again controlled by the controller's toggle switch.
