[0042] Embodiment One

[0043] Figure 1 is a schematic diagram of a multi-light source automatic identification matching output system according to an exemplary embodiment, the system comprising:

[0044] A plurality of different parameter light sources, each of which is connected with a light source coding circuit 1, the light source coding circuit 1 being used to encode the parameters of the light source into a digital coded signal for identification of the light source;

[0045] Each light source coding circuit 1 is connected to the input end of a light source identification board 2, the light source identification board 2 being used to identify the digital coded signal and output a control signal;

[0046] The output end of the light source identification board 2 is connected to the input end of a light source driving power supply 3, the light source driving power supply 3 outputting the working parameters corresponding to the light source according to the control signal to power the corresponding light source;

[0047] It can be understood that the light source and the light source coding circuit 1 in the present application are fixed together on a water-cooled assembly, and the light source coding circuit 1 corresponds to the light source one by one. When different light sources are switched, the n-bit digital coded signal coded by the light source coding circuit also changes accordingly. In short, each different light source corresponds to an n-bit digital coded signal. For the convenience of understanding, the subsequent content of the present embodiment takes a three-bit digital coded signal as an example. The present application encodes the corresponding light source through the light source coding circuit 1, decodes the light source through the light source identification board 2, and then starts the light source driving power supply 3 to output the corresponding voltage and current to drive the light source, effectively avoiding the problem of cumbersome power supply adaptation and switching of different outputs in the prior art in the use of multiple light sources;

[0048] It can be understood that, as shown in the accompanying Figure 2 and the accompanyingFigure 5 As shown in the figure, the light source identification board 2 is provided with a power supply circuit 201, which is mainly composed of a power chip DC1, capacitors C12, C13, C14 and CE1, for converting the input DC power into the voltage required by each module to supply power to each functional module of the light source identification board 2.

[0049] It can be understood that, taking a three-digit digital coded signal as an example, as shown in the accompanying Figure 2 and the accompanying Figure 3 As shown in the figure, the light source coding circuit 1 is used to encode the power of the light source into a three-digit digital coded signal, and the light source identification board 2 includes a decoding circuit 203 and an output signal switching circuit 204; the decoding circuit 203 is used to identify the three-digit digital coded signal sent by the light source coding circuit 1 and generate an eight-digit digital level signal to the output signal switching circuit 204; the output signal switching circuit 204 is used to receive the eight-digit digital level signal and generate an analog signal of the light source power according to the eight-digit digital level signal.

[0050] It can be understood that, as shown in the accompanying Figure 2 and the accompanying Figure 6 As shown in the figure, the light source identification board 2 further includes a filter circuit 201; the filter circuit 201 is composed of a π-type filter, which is responsible for filtering high-frequency interference of the transmitted three-digit digital coded signal to prevent errors in identifying the light source model.

[0051] It can be understood that, as shown in the accompanying Figure 2 and the accompanying Figure 4 As shown in the figure, the light source coding circuit 1 includes a three-digit DIP switch and a 4-pin connector; the three-digit DIP switch is connected to three ports of the 4-pin connector, and the other port of the 4-pin connector is grounded; the three-digit DIP switch outputs 0 or 1 signal to the 4-pin connector through its own on-off, and the 4-pin connector generates a three-digit digital coded signal such as 011, 110 and 101 according to the received 0 or 1 signal; if it is a four-digit DIP switch, then it corresponds to a 5-pin connector, and the four-digit DIP switch corresponds to a four-digit digital coded signal, and the four-digit digital coded signal corresponds to a 16-digit digital level signal.

[0052] It can be understood that, as shown in the accompanying Figure 2 and the accompanying Figure 7As shown, the decoding circuit 203 consists of three NOT gates and eight three-input AND gates. Each NOT gate has one input and one output; its logical function is to invert the input signal. That is, when the input is high (logic "1"), the output is low (logic "0"), and vice versa. NOT gates are widely used in digital circuits such as flip-flops and registers to achieve logical negation, ensuring that the output is the opposite of the input. The AND gate, also known as an AND circuit, logical "product," or logical "AND" circuit, has multiple inputs and one output. When all inputs are simultaneously high... The output is high (logic "1") only when the logic level is 1; otherwise, the output is low (logic "0"). AND gates are used in digital circuits to ensure that an event occurs only when all conditions are met. Through the cooperation of 3 NOT gates and 8 three-input AND gates, the filtered 3-bit digital encoded signal output by the filter circuit 201 is converted into an 8-bit digital level signal output. The 8-bit digital level signal includes 1 high-level signal and 7 low-level signals. The 3-bit digital encoded signal determines the position of the high-level signal in the 8-bit digital level signal.

[0053] Understandably, as shown in the attached document Figure 2 Appendix Figure 3 and appendix Figure 8 As shown, the output signal switching circuit 204 is composed of resistors R12 and R14, adjustable potentiometer R13, LED D3, diode D2, relay RLY1, and output interface P2. Its number is consistent with the number of light sources. Its function is to convert the 8-bit digital level signal output by the decoding circuit 203 into an analog signal and output it to the light source driving circuit 3 through interface P2. Specifically, the 8-bit digital level signal output by the decoding circuit 203 drives the output signal to enable the relay RLY1 in the switching circuit 204. After the relay RLY1 is activated, it outputs the voltage (i.e., the control signal) on the corresponding adjustable potentiometer R13 to the P2 interface of the light source driving power supply 3. After receiving the analog signal, the light source driving circuit 3 outputs the voltage and current corresponding to the light source.
