[0058] Further, please refer to Figure 2 , Figure 2 This is a circuit diagram of one embodiment of the switch-selection lamp color temperature angle adjustment circuit provided in this application. The following is a description of the circuit schematic. Figure 2 The circuit design shown further explains the working principle of each module. The following is a detailed explanation of the light source module 1:
[0059] The light source module 1 includes a first angle light source unit 11, which includes a first light source LED, a second light source LED, and a third light source LED connected in series, as well as a fourth light source LED, a fifth light source LED, and a sixth light source LED connected in series. The positive terminal of the first light source LED is connected to a DC signal source, and the negative terminal of the third light source LED is connected to the first input pin of the first angle toggle switch 21; the positive terminal of the fourth light source LED is connected to the DC signal source, and the negative terminal of the sixth light source LED is connected to the second input pin of the first angle toggle switch 21.
[0060] Specifically, when the DC signal source Vin+ is powered on and outputs a DC signal, the DC signal is output to the angle switch module 2 through the first light source LED, the second light source LED and the third light source LED, or through the fourth light source LED, the fifth light source LED and the sixth light source LED, thereby realizing the current flow direction in different circuits.
[0061] Furthermore, to improve the practicality and functionality of the circuit lighting, another light source unit can be set up for illumination. That is, the light source module 1 also includes a second angle light source unit 12, which includes a seventh light source LED, an eighth light source LED, and a ninth light source LED connected in series, as well as a tenth light source LED, an eleventh light source LED, and a twelfth light source LED connected in series. The positive terminal of the seventh light source is connected to the DC signal source, the negative terminal of the ninth light source LED is connected to the first input pin of the second angle toggle switch 22, the positive terminal of the tenth light source LED is connected to the DC signal source, and the negative terminal of the twelfth light source LED is connected to the second input pin of the second angle toggle switch 22.
[0062] Specifically, when the DC signal source Vin+ is powered on and outputs a DC signal, the DC signal is output to the angle switch module 2 through the seventh, eighth, and ninth light source LEDs, or through the tenth, eleventh, and twelfth light source LEDs, thereby realizing the current flow direction in different circuits.
[0063] Furthermore, whether the DC signal output from the DC signal source Vin+ passes through the light source module 1 is controlled by the angle switch module 2 and the color temperature switch module 3. When both the angle switch module 2 and the color temperature switch module 3 are turned on, the DC signal Vin+ can pass through the light source module 1 to achieve LED lighting. The angle switch module 2 will be explained in detail below with reference to the circuit design:
[0064] The angle switch module 2 includes a first angle toggle switch 21 and a second angle toggle switch 22, which are formed by combining multiple toggle switches. The first angle toggle switch 21 includes two input pins and two output pins, and the second angle toggle switch 22 includes two input pins and two output pins. The two input pins of the first angle toggle switch 21 are connected to one output terminal of the light source module 1, the first output pin of the first angle toggle switch 21 is connected to the first input pin of the color temperature toggle switch 31, and the second output pin is connected to the fourth input pin of the color temperature toggle switch 31. The two input pins of the second angle toggle switch 22 are connected to the other output terminal of the light source module 1, the second output pin of the second angle toggle switch 22 is connected to the fourth input pin of the color temperature toggle switch 31, and the first output pin is connected to the connection point between the first angle toggle switch 21 and the color temperature toggle switch 31.
[0065] Specifically, the design incorporates multiple toggle switches. When the color temperature switch module 3 is turned on and the first angle toggle switch 21 is closed, the DC signal output from the light source module 1 can flow through the first angle toggle switch 21 and the color temperature switch module 3, thereby turning on the LED in the first angle light source unit 11. Similarly, when the second angle toggle switch 22 is closed, the LED in the second angle light source unit 12 can also be turned on, thus achieving color temperature and angle control of the LED lamp.
[0066] Furthermore, to improve the multi-angle illumination of the circuit lighting, another angle toggle switch can be provided to achieve multi-angle LED illumination. Specifically, the angle switch module 2 also includes a third angle toggle switch 23 formed by combining multiple toggle switches. The third angle toggle switch 23 includes four input pins and four output pins. The first input pin connects to the connection between the first angle toggle switch 21 and the third light source LED; the second input pin connects to the connection between the first angle toggle switch 21 and the sixth light source LED; the third input pin connects to the connection between the second angle toggle switch 22 and the twelfth light source LED; and the fourth input pin connects to the connection between the second angle toggle switch 22 and the ninth light source LED. The first output pin of the third angle toggle switch 23 connects to the connection between the first angle toggle switch 21 and the color temperature toggle switch 31; the second output pin connects to the connection between the second angle toggle switch 22 and the color temperature toggle switch 31; the third output pin connects to the connection between the first output pin and the color temperature toggle switch 31; and the fourth output pin connects to the connection between the second output pin and the color temperature toggle switch 31.
[0067] Specifically, a design incorporating multiple toggle switches is adopted. When the color temperature switch module 3 is turned on and the third angle switch is closed, the DC signal output from the light source module 1 can flow through the third angle toggle switch 23 and the color temperature switch module 3, enabling the LEDs in the first angle light source unit 11 and the second angle light source unit 12 to conduct, allowing flexible adjustment of the color temperature and angle of the lamp. In this embodiment, the turning on of the angle switch module 2 allows the DC signal source to flow through the color temperature switch module 3. After the color temperature switch module 3 is turned on, it determines the conduction of the angle light source units in the light source module 1, thereby achieving color temperature and angle control of the LED lamp. The color temperature switch module 3 will be described in detail below:
[0068] The color temperature switch module 3 includes a color temperature toggle switch 31 formed by combining multiple toggle switches. The color temperature toggle switch 31 includes four input pins and four output pins. Two input pins of the color temperature toggle switch 31 are connected to one output terminal of the angle switch module 2, and the other two input pins are connected to the other output terminal of the angle switch module 2. The four output pins are all connected to the negative terminal Vin- of the external drive power supply to form a circuit.
[0069] Specifically, the design incorporates multiple toggle switches. The color temperature toggle switch 31 provides three settings. By closing the corresponding setting, a DC signal source can flow through the light source module 1, angle switch module 2, and color temperature switch module 3, thereby turning on the light source module 1. This allows the color temperature and angle of the LED lamp to be switched using the angle switch module 2 and color temperature switch module 3. Furthermore, the color temperature of the LED beads can be set in the light source module 1 of the switch-selection lamp color temperature and angle adjustment circuit of this application. In this embodiment, two types of LED beads with different color temperatures, cool and warm, are used, as detailed below:
[0070] The first, second, third, seventh, eighth, and ninth light sources use cool color temperature LEDs; the fourth, fifth, sixth, tenth, eleventh, and twelfth light sources use warm color temperature LEDs.
[0071] Specifically, when both the color temperature switch module 3 and the angle switch module 2 are turned on, the color temperature and angle of the LED lamp can be controlled.
[0072] A second aspect of this application provides an LED lamp fixture equipped with the aforementioned switch-selection circuit for adjusting the color temperature angle of the lamp fixture. The LED lamp fixture includes a plurality of lenses disposed above the first and fourth light source LEDs, the second and fifth light source LEDs, and the third and sixth light source LEDs; the lens abutment angle is set to 60°.
[0073] Furthermore, the LED lamp also includes several lenses disposed above the seventh and tenth light source LEDs, the eighth and eleventh light source LEDs, and the ninth and twelfth light source LEDs; the lens acupoint angle is set to 90°.
[0074] Specifically, by setting lenses above each group of LED light sources, the lamps can achieve different lighting angles. Users can easily select the appropriate color temperature and angle by toggling the angle switch, thereby meeting the lighting needs of different scenarios.
[0075] It should be noted that the color temperature toggle switch 31 of this utility model has at least three positions, including an upper position, a middle position, and a lower position. By switching the color temperature toggle switch in the lamp color temperature angle adjustment circuit to different positions, different LED circuits in the light source module 1 can operate normally. Furthermore, the number of LEDs connected in series in each group of light sources can be three or more, and this application does not impose any limitation. The angle switch module 2 realizes the switching of different lighting angles of the LED lamp, wherein the first angle toggle switch 21 realizes a 60° lighting angle, the second angle toggle switch 22 realizes a 120° lighting angle, and the third angle toggle switch 23 realizes a 90° lighting angle based on 60° and 120°. Through the control of the color temperature toggle switch 31, the first angle toggle switch 21, the second angle toggle switch 22, and the third angle toggle switch 23, the color temperature angle control of the LED lamp is realized, thereby improving the practicality of this utility model.

[0090] For example, when a user selects a cool color temperature of 60°, the corresponding indicator light will illuminate to indicate the current setting. Similarly, when a user selects a warm color temperature of 90°, another set of indicator lights will illuminate, allowing the user to quickly confirm the current setting. This makes it easier for users to understand the current lighting status during use and avoids unnecessary trouble caused by misoperation.
