[0026] Currently, consumers have an increasing demand for customized lighting fixtures, such as diverse lamp panel configurations, power output, and color temperature selection. However, traditional solutions rely on expensive and complex components (such as microcontroller units or relays). While these solutions offer high control precision and flexibility, they also significantly increase costs and introduce technical complexity, limiting the applicability and market competitiveness of the products.

[0027] Therefore, this utility model embodiment provides a control circuit that simultaneously cuts color temperature, lamp board power, and LED power, thereby significantly reducing production costs and simplifying system architecture while maintaining existing functions, thus better adapting to changing market demands.

[0028] Specifically, by employing DIP switches as the switching mechanism, the color temperature adjustment and power control functions of the LED lamps are realized, while simplifying circuit design and reducing production costs. Specifically, using simple three-position DIP switches K1 and K2 instead of traditional microcontrollers or relays not only allows for flexible control of the operating status and color temperature selection of the upper and lower lamp panels 40, but also reduces hardware complexity and software development requirements. Furthermore, the direct connection method and modular design (such as the upper and lower lamp panels 40) make the entire system more intuitive and concise, facilitating production and maintenance. This significantly reduces manufacturing costs and system complexity while maintaining or even enhancing product performance, better adapting to changing market demands. This cost-effective design is particularly suitable for product environments requiring rapid iteration and high cost-performance.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] Please see Figure 1 The control circuit for cutting color temperature, lamp board, and power simultaneously includes: LED power supply 10, switching board 20, and lamp board. LED power supply 10 is connected to switching board 20; switching board 20 is connected to lamp board; switching board 20 includes DIP switches.

[0031] In one embodiment, please refer to Figure 1 The aforementioned switchboard 20 includes a three-position DIP switch.

[0032] In this embodiment, the function control of the LED lamp is achieved by using a DIP switch. Specifically, the circuit includes three main components: an LED power supply 10, a switching board 20, and a lamp board. The LED power supply 10 provides the necessary power support for the entire system; the switching board 20 acts as an intermediate bridge, connecting the LED power supply 10 and the lamp board, and uses the DIP switches integrated on it to select and control the lighting mode, power output, and color temperature of the lamp board.

[0033] In one embodiment, the switching board 20 employs a three-position DIP switch to control different lighting modes of the two lamp panels (upper lamp panel 30 and lower lamp panel 40): only the upper lamp panel 30 is lit, both lamp panels 40 are lit, or only the lower lamp panel 40 is lit. This design not only diversifies lighting needs but also automatically adjusts power consumption based on actual lighting conditions; for example, power consumption is 50% when a single lamp is lit, while power reaches 100% when both lamps are lit. Furthermore, the three-position DIP switch is used to adjust the color temperature, providing three different color temperature options (e.g., 3000K, 4000K, 5000K) to meet the color temperature requirements of different users.

[0034] It is worth noting that the circuit in this embodiment specifically emphasizes that the LED driver power supply used does not need to have 0-10V dimming functionality, which simplifies the circuit design and makes it more cost-effective. Compared to other solutions, such as those using relays or microcontroller units for control, the pure hardware solution provided by this invention avoids expensive costs and complex programming work, while also reducing the required space, making it easier to deploy and maintain in various application scenarios.

[0035] In summary, the circuit in this embodiment implements complex control logic through a simple mechanical DIP switch, effectively reducing production costs, simplifying the system architecture, and improving the market adaptability of the product. It is very suitable for lighting products that require flexible configuration and pursue high cost performance.

[0036] In one embodiment, please refer to Figure 2 The aforementioned three-position DIP switch includes switch K1 and switch K2.

[0037] In one embodiment, please refer to Figure 2 The aforementioned light panel includes an upper light panel 30 and a lower light panel 40.

[0038] In one embodiment, please refer to Figure 2 The aforementioned switch K2 is connected to the lower lamp plate 40.

[0039] In one embodiment, please refer to Figure 2 The aforementioned switch K1 is connected to the lower lamp plate 40 and the upper lamp plate 30 respectively.

[0040] In one embodiment, please refer to Figure 2 The aforementioned switches K1 and K2 are respectively connected to the LED power supply 10.

[0041] In one embodiment, please refer to Figure 2 The aforementioned upper light panel 30 includes several LED lights.

[0042] In one embodiment, please refer to Figure 2 The aforementioned lower light panel 40 includes several LED lights.

[0043] In this embodiment, the LED power supply 10 provides the necessary power support to the system and is connected to the lamp board through DIP switches K1 and K2 to realize the selection and control of the lamp board's lighting mode, power output and color temperature.

[0044] Function of DIP switch K1:

[0045] Three-level selection: K1 is used to control different lighting modes of the two light panels.

[0046] Level 1: Only the upper light panel 30 is lit. At this time, the two ends of the lower light panel 40 are short-circuited, the output voltage of the LED driver is halved, and the power consumption is 50%.

[0047] Level 2: Both upper and lower light panels are lit at 40°. At this time, the output voltage of the LED driver increases and the power consumption reaches 100%.

[0048] Level 3: Only the lower light panel 40 is lit. Similarly, the two ends of the upper light panel 30 are short-circuited, the output voltage of the LED driver is halved, and the power consumption is 50%.

[0049] Function of DIP switch K2:

[0050] Three settings: K2 is used to control the color temperature selection of the lamp panel.

[0051] Level 1: Connect LED- to WW2- and set the color temperature to 3000K.

[0052] Level 2: LED-connected to both CW2- and WW2-, color temperature set to 4000K.

[0053] Level 3: Connect LED to CW2, set the color temperature to 5000K.

[0054] The upper light panel 30 contains several LEDs, which are responsible for lighting up under specific conditions to meet lighting needs.

[0055] The lower light panel 40 also contains several LEDs, which are turned on or off according to the settings of K1.

[0056] The LED driver power supply used does not need to have 0-10V dimming function, which simplifies the circuit design and reduces costs.

[0057] The circuit in this embodiment avoids the use of expensive components such as MCUs or relays, implementing complex control logic through pure hardware, thus reducing development cycle and maintenance difficulty. It can meet the diverse needs of different customers for lamp boards, power, color temperature, and light control, offering high market flexibility. Due to the use of simple mechanical DIP switches, the entire control system occupies a very small space, making it suitable for various compact lighting designs.

[0058] The circuit in this embodiment cleverly utilizes DIP switches to achieve precise control of multiple functions of LED lighting fixtures. This not only greatly simplifies circuit design but also significantly reduces production costs and improves system reliability and maintainability. It is particularly suitable for the lighting product market that requires flexible configuration while pursuing cost-effectiveness, demonstrating its enormous potential in practical applications.

[0059] In this embodiment, the control circuit uses a three-position DIP switch to switch between different lighting modes for the two lamp panels (lamp 1 on; lamp 1 and lamp 2 on; lamp 2 on). Furthermore, the power switching varies depending on the lighting status of the selected lamp panel: when only one lamp panel is lit (lamp 1 or lamp 2), the power is 50%; when both lamp panels are lit (lamp 1 and lamp 2), the power is 100%. Color temperature switching is also achieved through another three-position DIP switch, providing three different color temperature combinations (e.g., 3000K, 4000K, 5000K), specifically: position 1 corresponds to 3000K, position 2 corresponds to 4000K, and position 3 corresponds to 5000K. The light control function is controlled by a two-position DIP switch.

[0060] The circuit in this embodiment uses a more common power supply that only provides output and has no other functions. Therefore, it is more suitable for more demanding conditions in practical applications, has greater universality, and has a simpler circuit design.

[0061] The control circuit in this embodiment is not only simple in structure, avoiding the use of MCU or manual judgment for control, but also inexpensive, avoiding the use of expensive MCU or relays, and requires very little space.

[0062] In one embodiment, a three-position DIP switch is used to control the switching of the lighting modes of the two lamp panels.

[0063] In one embodiment, the same three-position DIP switch is used to control the power switching of the two lamp panels.

[0064] In one embodiment, a DIP switch is used to simultaneously control the switching of the lamp panel and the change of power.

[0065] In one embodiment, a three-position DIP switch is used to control the three color temperature selections of the lamp panel.

[0066] In one embodiment, the LED power supply 10 used does not need to have 0-10V dimming function.

[0067] The control circuit in this embodiment uses a pure hardware method to simultaneously control lamp board switching and power adjustment, aiming to solve the problems of high price, large size and long development cycle of existing control circuits, while also more flexibly meeting the different needs of different customers for lamp boards, power, color temperature and light control.

[0068] Specifically, the control circuit of this embodiment can simultaneously control lamp board switching and power adjustment, and meet the different choices of different customers for lamp board, power, color temperature and light control.

[0069] The operating modes of switches K1 and K2 are as follows:

[0070] Gear 1: 1-2 and 7-8 are respectively turned on;

[0071] Second gear: 2-3 and 7-6 are turned on respectively;

[0072] Level 3: 2-4 and 7-5 are turned on respectively.

[0073] The following is an analysis of the simultaneous switching of lamp panels and adjustment of power circuitry:

[0074] When switch K1 is set to position 1, the upper light panel 30 lights up and the lower light panel 40 turns off. The two ends of the lower light panel 40 are short-circuited by K1, and the output voltage of LED power supply 10 is half (denoted as Vled), and the power is 50%.

[0075] When switch K1 is set to position 2, both the upper and lower light panels 40 are lit, and the output voltage of LED power supply 10 is 2*Vled, which is obtained by connecting the upper and lower light panels 40 in series, and the power is 100%.

[0076] When switch K1 is set to position 3, the upper light panel 30 is off and the lower light panel 40 is on. The two ends of the upper light panel 30 are short-circuited by K1, and the output voltage of LED power supply 10 is half (denoted as Vled), and the power is 50%.

[0077] CW2- and WW2- of the lower light panel 40 are connected to the power supply K2.

[0078] When switch K2 is set to position 1, LED- is connected to WW2-, and the color temperature is 3000K.

[0079] When switch K2 is set to position 2, LED- is connected to both CW2- and WW2- simultaneously, with a color temperature of 4000K.

[0080] When switch K2 is set to position 3, LED- is connected to CW2-, and the color temperature is 5000K.

[0081] The aforementioned control circuit for simultaneously switching color temperature, lamp board, and power integrates the LED power supply 10, switching board 20, and lamp board. It utilizes DIP switches on the switching board 20 to flexibly switch between color temperature, lamp board lighting mode, and power. This not only maintains the integrity and versatility of existing functions but also significantly reduces production costs and simplifies the system architecture. The DIP switch design avoids the need for expensive and complex MCU or relay control, making the entire system more economical and compact. This simplified hardware implementation not only reduces development time and manufacturing costs but also improves system stability and reliability, enabling it to adapt more quickly to changing market demands and meet the diverse needs of different customers for lighting products. Furthermore, its independence from power supplies with specific functions such as 0-10V dimming further enhances its versatility and market competitiveness.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
