[0024] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] A multi-functional DIP switch adjustment circuit includes a DIP switch module and a drive module. The DIP switch module includes an operation switch, at least two current paths, and at least two light source paths. Each current path has a different current value, and each light source path is connected to the negative terminal of a light source with a different color temperature. The operation switch selects and connects any of the current paths to the control terminal of the drive module. The operation switch also selects and connects any of the light source paths to the negative output terminal of the drive module. The positive output terminal of the drive module is connected to the positive terminals of all the light sources. The input terminal of the drive module is used to connect to a power supply.

[0026] As can be seen from the above description, the beneficial effects of this utility model are as follows: by setting multiple current paths and light source paths, and each current path has a different current value and each light source path has a different color temperature, after any current path and light source path are selected and connected to the circuit by operating the switch, the dimming function can be realized based on different current paths, and the color adjustment function can be realized based on different light source paths. The color temperature adjustment and dimming functions can be realized simultaneously by operating the switch, thereby solving the problems of large size, unsightly appearance and high cost of LED products.

[0027] Furthermore, the DIP switch module includes a common ground terminal; the control terminal of the drive module is connected to the input terminals of all the current paths; and the operation switch selects and connects the output terminal of any of the current paths to the common ground terminal.

[0028] As described above, by setting a common ground terminal and using an operating switch to select and connect different current paths to the common ground terminal, different current paths can be selected while avoiding the problem of large LED product size caused by setting multiple ground terminals.

[0029] Furthermore, each of the current paths includes a resistor, and the resistance values ​​of the resistors in different current paths are different; one end of each resistor is connected to the control terminal of the drive module; the other end of each resistor is selectively connected to the ground common terminal through the operation switch.

[0030] As described above, by using resistors with different resistance values ​​as current paths, the current value of the circuit can be controlled through different resistors, so that the current value of the light source is different when different current paths are connected, thereby realizing the dimming function.

[0031] Furthermore, the DIP switch module includes an output common terminal; the input terminal of each of the light source paths is connected to the negative terminal of a light source with a different color temperature; the DIP switch module selects and connects the output terminal of any of the light source paths to the output common terminal.

[0032] As described above, by setting a common output terminal and selecting different light source paths to the common output terminal through an operating switch, different light source paths can be selected while avoiding the problem of large LED product size caused by setting multiple output terminals.

[0033] Furthermore, each of the aforementioned light source paths corresponds to one of the aforementioned current paths.

[0034] As described above, by matching the light source path with the current path one by one, the current path is switched simultaneously when different light source paths are selected, thereby achieving simultaneous changes in the color temperature and brightness of the LED.

[0035] Furthermore, the input end of the light source path is connected to the negative electrode of at least two color temperature light sources.

[0036] As described above, by connecting the input end of the light source path to multiple light sources, the light source path can be connected to the color temperature formed by one light source, or to a mixed color temperature formed by multiple light sources, thereby forming multiple color temperature combinations.

[0037] Furthermore, it also includes a multi-color temperature access unit; the input terminal of the multi-color temperature access unit is connected to the negative electrode of at least two color temperature light sources; the output terminal of the multi-color temperature access unit is connected to the input terminal of the light source path.

[0038] As can be seen from the above description, by setting up a multi-color temperature access unit, light sources of different color temperatures can be effectively connected to the light source path.

[0039] Furthermore, the multi-color temperature access unit includes at least two diodes; the positive terminal of each diode is connected to the negative terminal of a light source of a different color temperature; and the negative terminal of each diode is connected to the input terminal of the light source path.

[0040] As described above, by setting multiple diodes and connecting each diode to the negative terminal of a light source with a different color temperature, all light sources can be connected into the light source path through the negative terminals of the diodes, thereby effectively connecting light sources with different color temperatures into the light source path.

[0041] Furthermore, each of the diodes is connected in series with resistors of different resistance values.

[0042] As described above, by connecting resistors with different resistance values ​​in series with the diode, the current value of the diode can be controlled by the different resistors. This results in different current values ​​for lighting the light source when different diodes are connected. This allows different color temperatures to be produced even when two identical light sources are connected to different light source paths, by setting different resistors.

[0043] Furthermore, the driving module includes a rectifier unit, a filter unit, and a switch driving unit; the input terminal of the rectifier unit is connected to a power supply; the output terminal of the rectifier unit is connected to the input terminal of the filter unit; the output terminal of the filter unit is connected to the input terminal of the switch driving unit; the operating switch selects and connects any of the current paths to the control terminal of the switch driving unit; the operating switch selects and connects any of the light source paths to the negative output terminal of the switch driving unit; the positive output terminal of the switch driving unit is connected to the positive terminals of all the light sources.

[0044] As described above, by setting up a rectifier unit, AC mains power can be converted into DC power, and by setting up a filter unit, the converted DC power can be filtered to provide a stable DC power supply for subsequent modules. In addition, a switch drive unit is set up to realize voltage changes and provide the corresponding voltage for the light source.

[0048] The driving module 2 includes a rectifier unit 21, a filter unit 22, and a switch driving unit 23. The input terminal of the rectifier unit 21 is connected to a power supply. The output terminal of the rectifier unit 21 is connected to the input terminal of the filter unit 22.

A fuse resistor F1 is also provided at the live wire terminal (L) of rectifier bridge BR1.

LEDA and LEDB are light sources with different color temperatures.

[0049] like Figure 1 As shown, the DIP switch module 1 includes upper row pins 0-5 and lower row pins 0-5, each with a corresponding configuration. Upper row pins 2-3 are the common ground terminal (GND), and pins 0, 1, 4, and 5 can respectively form four current paths 11. Lower row pins 2-3 are the common output terminal (LED-), and pins 0, 1, 4, and 5 can respectively form four light source paths 12. The control terminal of the drive module 2 is connected to the input terminal of each current path 11, i.e., the control terminal (CS) of the constant current chip IC1 is connected to the input terminal of each current path 11. The operation switch K selects and connects the output terminal of any current path 11 to the common ground terminal. Each current path 11 includes a resistor, and the resistance values ​​of the resistors in different current paths 11 are different. One end of each resistor is connected to the control terminal of the drive module 2; the other end of each resistor is selected and connected to the common ground terminal through the operation switch K. The input terminal of each light source path 12 is connected to the negative terminal of a light source with a different color temperature; the DIP switch module 1 selects and connects the output terminal of any light source path 12 to the common output terminal.

[0050] like Figure 1 As shown, in this embodiment, pins 0 and 1 in the upper row are both connected to resistor R3, meaning the current channels formed by pins 0 and 1 have the same current value and can be considered as one current channel. Pins 4 and 5 in the upper row are both connected to resistor R5, also considered as one current channel. Pins 0 and 4 in the lower row are both connected to the negative terminal of LEDA, also considered as one light source channel, and pins 1 and 5 are both connected to the negative terminal of LEDB, also considered as one light source channel. Therefore, two different current channels and two different light source channels are formed.

[0051] The specific dimming and color tuning principles in the above embodiments are as follows:

[0052] When the operating switch K is set to the first position on the left, pins 0 and 2 on the upper row are connected, and pins 0 and 2 on the lower row are connected, so that resistor R3 and LEDA are connected to the circuit. At this time, resistors R3 and R2 are connected in parallel to form the first current path 11, that is, to set the first power and the first color temperature.

At this time, resistors R3 and R2 are still connected in parallel, which means that the first power and the second color temperature are set.

[0054] When the operating switch K is moved to the third position on the left, pins 2 and 4 on the upper row are connected, and pins 2 and 4 on the lower row are connected, so that resistor R5 and LEDA are connected to the circuit. At this time, resistors R5 and R2 are connected in parallel to form the second current path 11, that is, to set the second power and the first color temperature.

At this time, resistors R5 and R2 are still connected in parallel, which means that the second power and the second color temperature are set.

[0056] Please refer to Figure 2 In another alternative implementation, each light source path 12 corresponds to one current path 11; such as Figure 2 As shown, each pin in the upper row is connected to a different resistor, thus forming four different circuit paths. Simultaneously, the input terminal of the light source path 12 is connected to the negative terminals of at least two color temperature light sources; wherein, the light source path 12 is connected to multiple light sources through a multi-color temperature access unit; the input terminal of the multi-color temperature access unit is connected to the negative terminals of at least two color temperature light sources; the output terminal of the multi-color temperature access unit is connected to the input terminal of the light source path 12; the multi-color temperature access unit includes at least two diodes; the anode of each diode is connected to the negative terminal of a light source of a different color temperature; the cathode of each diode is connected to the input terminal of the light source path 12.

Each diode can also be connected in series with resistors of different resistance values; for example... Figure 2 As shown, the two diodes on pin 4 of the lower row are connected to resistors R10 and R11 respectively, thereby adjusting the current of LEDA and LEDB to form the fourth color temperature; the two diodes on pin 5 of the lower row are connected to resistors R12 and R13 respectively, thereby adjusting the current of LEDA and LEDB to form the fifth color temperature.

At this time, resistors R6 and R2 are connected in parallel to set the first current path 11, that is, to set the first power and the first color temperature.

[0060] When the operating switch K is set to the second position on the left, pins 1 and 3 of the upper row are connected, and pins 1 and 3 of the lower row are connected, so that resistor R7 and LEDB are connected to the circuit. At this time, resistors R7 and R2 are connected in parallel to form the second current path 11, that is, to set the second power and the second color temperature.

[0061] When the operating switch K is set to the third position on the left, pins 2 and 4 on the upper row are connected, and pins 2 and 4 on the lower row are connected, so that resistors R8, LEDA and R10, as well as LEDB and R11 are connected to the circuit. At this time, resistors R8 and R2 are connected in parallel to form the second current path 11, which sets the third power and the third color temperature.

[0062] When the operating switch K is set to the fourth position on the left, pins 3 and 5 on the upper row are connected, and pins 3 and 5 on the lower row are connected, so that resistors R9, LEDA and R12, as well as LEDB and R13 are connected to the circuit. At this time, resistors R9 and R2 are connected in parallel to form the second current path 11, that is, to set the fourth power and the fourth color temperature.
