[0028] The core of this utility model is to provide a color temperature adjustment control circuit and device. This solution can control the color temperature of the LED module, that is, the color temperature of the lamp, by controlling the color temperature sliding switch to select resistor submodules with different resistance values and LED modules to form a circuit, or only the LED module to form a circuit. Because the control method of this solution is to toggle the color temperature sliding switch, it avoids the mutual influence between multiple lamps in a space compared to infrared control solutions.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a color temperature adjustment control circuit provided by the present invention. The color temperature adjustment control circuit includes: a color temperature sliding switch 1, a resistor module 2, wherein the resistor module 2 includes a plurality of parallel resistor submodules, each having a different resistance value;

[0031] The ports in the color temperature slide switch 1 include several selection ports and several LED cathode ports. The selection ports are connected to the first end of each resistor submodule and the first end of the LED module in a one-to-one correspondence, and are used to select the first end of any resistor submodule or LED module in the resistor module 2 to be connected to the LED cathode port.

[0032] The second end of each resistor submodule is connected to the first end of the LED module;

[0033] The second end of the LED module is connected to a DC power supply, and the LED module includes a plurality of LED lamps connected in series.

[0034] In this invention, considering that existing color temperature control solutions use infrared technology to control the control circuitry of lamps, this solution can affect the actual color temperature control results because the infrared signal can be received simultaneously by multiple lamps in a space. Therefore, this solution provides a corresponding color temperature slide switch 1 and resistor module 2 for each lamp, that is, each LED (Light-Emitting Diode) module. Because the color temperature slide switch 1 has multiple selection ports, each of which is connected to different resistor sub-modules and LED modules, when the color temperature of the lamp needs to be adjusted, the color temperature slide switch 1 can be adjusted so that the target selection port and the LED cathode port form a circuit. Because the target selection port is connected to any resistor sub-module or LED module, this solution can adjust the LED module, that is, the color temperature of the lamp, by adjusting the path of LED modules with different resistance values. Moreover, because this solution controls by toggling the color temperature slide switch 1, it avoids mutual interference between multiple lamps in a space compared to infrared control solutions.

[0035] It's important to note that this solution uses a linear thyristor control circuit to adjust the lamp's color temperature via a color temperature slide switch 1. This circuit is compatible with both leading-edge and trailing-edge dimmers. The circuit output uses a constant current (chip control circuit) and achieves compatibility by adjusting the control voltage. By presetting lamp beads (LED modules) with different color temperatures and the control circuit, when sliding the color temperature slide switch 1, each node independently corresponds to a lamp bead with a different color temperature. This allows for different lamp bead combinations or the same lamp bead combination connected to resistor submodules with different resistance values.

[0036] This embodiment provides a color temperature adjustment control circuit and device. The color temperature adjustment control circuit is provided with a color temperature sliding switch 1 and a resistor module 2. The resistor module 2 includes a plurality of parallel-connected resistor sub-modules, each having a different resistance value. This solution can control the color temperature of the LED module, that is, the color temperature of the lamp, by controlling the color temperature sliding switch 1 to select resistor sub-modules with different resistance values to form a circuit with the LED module, or only the LED module to form a circuit. Because the control method of this solution is to toggle the color temperature sliding switch 1, it avoids mutual influence between multiple lamps in a space compared to the infrared control solution.

[0037] Based on the above embodiment:

[0038] As an optional embodiment, the present invention further includes: a DC power supply; the DC power supply includes:

[0039] The rectifier module has an input end connected to the AC power supply and an output end connected to the second end of the LED module.

[0040] In the present invention, considering that the power supply of the LED module is a DC power supply, and if the built-in power supply is too large, it is not convenient to carry, a rectifier module is provided in the color temperature adjustment control circuit. The rectifier module converts the AC power transmitted by the AC power supply into corresponding DC power to power the LED module, thereby reducing the volume of the circuit and making it more convenient to carry.

[0041] It should be noted that in actual applications, if the portability of the color temperature adjustment control circuit is taken into consideration, only one rectifier module can be set up. However, if there is no AC power supply for connection in daily use, an AC battery needs to be built into the color temperature adjustment control circuit to meet the usage requirements of multiple scenarios.

[0042] As an optional embodiment, it further includes: a protection device and / or a sliding resistor;

[0043] The protection device is connected to the positive pole of the AC power supply and the input terminal of the rectifier module respectively, and is used to disconnect when an overcurrent occurs in the circuit where the protection device is located;

[0044] The first end of the sliding rheostat is connected to the positive electrode of the AC power supply and the input end of the rectifier module respectively, and the second end is connected to the negative electrode of the AC power supply and the input end of the rectifier module respectively.

[0045] In the present invention, taking into account that an overcurrent may occur in the circuit of the color temperature adjustment control circuit after the DC power supply is connected, thereby damaging the LED module and other devices, the present solution sets a protection device between the positive pole of the AC power supply and the input terminal connection of the rectifier module. When an overcurrent occurs in the circuit where the protection device is located, the protection device is automatically disconnected to protect the LED module and other devices in the circuit, thereby improving the safety of the solution; in addition, considering that in actual application, if the number of multiple resistance sub-modules in the resistance module 2 is fixed, the color temperature cannot be adjusted on this basis, so the present solution newly adds a sliding rheostat. If you want to make changes based on the original multiple mode color temperatures, you can change the color temperature of the LED module by changing the resistance value of the sliding rheostat, which is convenient for practical use.

[0046] As an optional embodiment, any resistance sub-module includes a plurality of resistors connected in parallel, and each resistance sub-module includes a different number of resistors.

[0047] In the present invention, any resistor submodule is provided with a plurality of resistors connected in parallel, and the number of resistors in parallel in each resistor submodule is different. Then, the corresponding resistor submodule can be connected to the LED module by selecting the color temperature sliding switch 1, thereby ensuring the integrity of the solution.

[0048] As an optional embodiment, the color temperature sliding switch 1 includes a port and a sliding brush contact, wherein the port includes a plurality of selection ports and a plurality of LED cathode ports, and the selection port and the LED cathode port are both copper sheets, which are used to select any resistor sub-module or LED module in the resistor module 2 to be connected to the first end of the LED cathode port based on the moving position of the sliding brush contact.

[0049] In the present invention, a port and a sliding brush contact are provided in the color temperature sliding switch 1, wherein the port includes a plurality of selection ports and a plurality of LED cathode ports, and the selection port and the LED cathode port are both copper sheets. The actual control of the color temperature sliding switch 1 is to select the first end of any resistor submodule or LED module in the resistor module 2 to be connected to the LED cathode port by changing the moving position of the sliding brush contact, that is, to turn on any resistor submodule and LED module or only turn on the LED module. Because the contact of the color temperature sliding switch 1 is brushed, the brush head in the color temperature sliding switch 1 can greatly reduce the friction coefficient with the copper sheet, that is, it has good contact, and can ensure that the output voltage and current are given to the corresponding LED module through the brush head and the copper sheet to achieve the corresponding power and color temperature of the color temperature sliding switch 1.

[0050] As an optional embodiment, the method further includes:

[0051] The dimmer has a control end connected to the controller, an input end connected to the AC power supply, and an output end connected to the rectifier module, and is used to output a corresponding PWM dimming signal to the LED module based on the control of the controller.

[0052] In the present invention, considering that users may have certain requirements for the brightness of the light in actual use, a dimmer is also provided in the color temperature adjustment control circuit of this solution, and the brightness of the LED module, that is, the lamp, is adjusted by the dimmer to meet the actual usage needs of the user.

[0053] As an optional embodiment, the method further includes:

[0054] A one-way conducting module, wherein the input end of the one-way conducting module is connected to the DC power supply, and the output end is connected to the second end of the LED module.

[0055] In the present invention, considering that the current transmitted by the DC power supply may flow back in actual use, a unidirectional conduction module is additionally provided in this solution. The input end of the unidirectional conduction module is connected to the DC power supply, and the output end is connected to the second end of the LED module. This can ensure that the DC power transmitted by the DC power supply accurately reaches the LED module, and current backflow will not occur, thereby improving the safety of the solution.

[0056] As an optional embodiment, the method further includes:

[0057] A filter module has a first end connected to the DC power supply and a second end connected to the second end of the LED module.

[0058] In the present invention, considering that when the DC power supply is powered on, the voltage it transmits may fluctuate accordingly, in order to smooth out the voltage fluctuation, this solution also adds a filter module between the DC power supply and the LED module to stabilize the voltage fluctuation through the filter module, thereby improving the stability of the solution.

[0059] It should be noted that, in practical applications, the filtering module may be a capacitor, or an inductor or other filtering components.

[0060] As an optional embodiment, the method further includes:

[0061] The chip control circuit has a power input terminal connected to a DC power supply, and a power output terminal connected to the LED cathode port of the color temperature slide switch 1, and is used to adjust the current output to the LED cathode port of the color temperature slide switch 1 based on the control.

[0062] In the present invention, in order to select any resistor sub-module in the resistor module 2 to be turned on with the LED module or to turn on only the LED module through the color temperature sliding switch 1, it is necessary to ensure that the current of the entire circuit is stable after the LED module is turned on. Therefore, the LED cathode port of the color temperature sliding switch 1 cannot be directly grounded. In this solution, an additional chip control circuit is provided. When the DC power supply is powered on, the chip control circuit starts and adjusts the current output to the LED cathode port of the color temperature sliding switch 1, thereby ensuring the stability of the current in the entire circuit after the color temperature sliding switch 1 is turned on.

[0063] The present invention also provides a corresponding embodiment of a color temperature adjustment control device, comprising: a plurality of color temperature adjustment control circuits as described above and a plurality of LED modules, wherein each color temperature adjustment control circuit is correspondingly connected to each LED module.

[0064] The color temperature adjustment control device provided in this embodiment corresponds to the above-mentioned color temperature adjustment control circuit and thus has the same beneficial effects as the color temperature adjustment control circuit. Therefore, for the embodiments of the color temperature adjustment control device, please refer to the description of the embodiments of the color temperature adjustment control circuit, and will not be repeated here.

[0065] It should be noted that, in practical applications, the structure of the color temperature sliding switch 1 is as follows: Figure 2 As shown, there are five gears. Taking one side as an example, the modes are A, M, B, L, D, J, E, H, F, and G, and C and K are connected to the negative pole of the power supply. Among them, A, B, C, D, E, and F are all positive poles. When the color temperature sliding switch 1 is switched to the corresponding positive pole, for example, it is switched to the A, M mode. At this time, because M is suspended, the circuit between A and C is turned on. At this time, the 17th to 32nd LEDs are turned on. When switched to the B, L mode, the 17th to 32nd LEDs are turned on, and the 1st to 16th LEDs are connected to the resistor sub-module connected in parallel with R6, R7, R8, and R9, and are turned on. Therefore, one color temperature sliding switch 1 can be connected to two LED modules, and the color temperature adjustment is completed by corresponding switching.

[0066] It should also be noted that the color temperature adjustment sliding switch of the lamp body uses a sliding brush contact to contact the fixed copper sheet. The brush head can reduce the friction coefficient with the copper sheet, and now has good contact, ensuring that the output voltage and current pass through the brush head and the copper sheet to give the corresponding lamp bead color temperature. The power load required reaches the power and color temperature corresponding to the switch.
