Please refer to fig. 1, which is a block diagram of an embodiment of a light source controller according to the present application. As shown in fig. 1, in the present embodiment, the light source controller 100 includes: the microcontroller circuit 110, the mode control circuit 120, the parameter setting circuit 130, the trigger circuit 140 and the output control circuit 150, wherein the mode control circuit 120, the parameter setting circuit 130, the trigger circuit 140 and the output control circuit 150 are electrically connected with the microcontroller circuit 110 respectively.

In practical implementation, the microcontroller circuit 110, the mode control circuit 120, the parameter setting circuit 130, the trigger circuit 140 and the output control circuit 150 can be implemented by analog circuits, Integrated Circuits (ICs), digital circuits and the like. Wherein, the integrated circuit can be, for example, a microprocessor (Micro-processor), a Microcontroller (MCU), a programmable logic gate array (FPGA or CPLD), or an Application Specific Integrated Circuit (ASIC), but the application is not limited thereto; the analog circuit may include a plurality of electronic components.

In an embodiment, the microcontroller circuit 110 includes a plurality of input/output (IO) pins, and the microcontroller circuit 110 is electrically connected to the mode control circuit 120, the parameter setting circuit 130, the trigger circuit 140, and the output control circuit 150 through the IO pins, respectively, for transmitting data/signals. In actual implementation, the microcontroller circuit 110 may be, but is not limited to, an STM32 single chip microcomputer.

In this embodiment, the mode control circuit 120 is configured to transmit a mode control signal to the microcontroller circuit 110 to set the operation mode of the light source controller 100 (i.e., the mode control circuit 120 sets the operation mode of the light source controller 100 through the microcontroller circuit 110); the parameter setting circuit 130 is configured to transmit a parameter setting signal to the microcontroller circuit 110 when the light source controller 100 is in different operating modes, so as to set the size of the corresponding parameter (i.e., when the light source controller 100 is in different operating modes, the parameter setting circuit 130 sets the size of the corresponding parameter through the microcontroller circuit 110); the trigger circuit 140 is used to send a trigger signal to the microcontroller circuit 110; the microcontroller circuit 110 continuously controls the output control circuit 150 to output the corresponding light source driving signal based on the trigger signal, the working mode set by the mode control circuit 120, and the corresponding parameter set by the parameter setting circuit 130, so that the light source (not drawn) electrically connected to the light source controller 100 continuously generates the corresponding light emitting mode based on the light source driving signal (i.e., the microcontroller circuit 110 continuously outputs the corresponding light source driving signal through the output control circuit 150 based on the trigger signal, the working mode set by the mode control circuit 120, and the corresponding parameter set by the parameter setting circuit 130, so that the light source continuously generates the corresponding light emitting mode based on the light source driving signal).

It should be noted that the microcontroller circuit 110 may control the output control circuit 150 to output the corresponding light source driving signal based on the currently received trigger signal, the operation mode set by the current mode control circuit 120, and the size of the corresponding parameter currently or previously set by the parameter setting circuit 130 (the size of the corresponding parameter previously set by the parameter setting circuit 130 may be stored in a memory (not shown) of the light source controller 100).

In an embodiment, the operating modes include an input/output mode and a strobe mode, the parameter corresponding to the input/output mode is a brightness parameter, and the parameter corresponding to the strobe mode is a time parameter. In one example, when the mode control circuit 120 transmits the mode control signal to the microcontroller circuit 110 and sets the light source controller 100 in the input/output mode, the parameter setting circuit 130 transmits the parameter setting signal to the microcontroller circuit 110 to set the magnitude of the brightness parameter, wherein the magnitude of the brightness parameter can be different brightness levels of the light source. In another example, when the mode control circuit 120 transmits another mode control signal to the microcontroller circuit 110 and sets the light source controller 100 in the strobe mode, the parameter setting circuit 130 transmits another parameter setting signal to the microcontroller circuit 110 to set the time parameter, wherein the time parameter can be the time duration of the normally on light source.

The light source driving signal and the trigger signal can be similar to TTL signals, the high potential of the light source driving signal can enable the light source to emit light, and the low potential of the light source driving signal can enable the light source to be extinguished; the larger the brightness parameter corresponding to the amplitude of the light source driving signal is, the larger the amplitude of the light source driving signal is; the smaller the brightness parameter corresponding to the amplitude of the light source driving signal is, the smaller the amplitude of the light source driving signal is; the higher the voltage value (i.e., amplitude) of the high potential of the light source driving signal, the higher the luminance at which the light source emits light. The high level of the light source driving signal may refer to a signal greater than or equal to a low level, and the low level may refer to a ground signal. It should be noted that the high voltage level of the light source driving signal may include a triangular wave (also called a sawtooth wave or a ripple wave).

The trigger signal can be similar to a pulse signal, the high potential of the light source driving signal can enable the light source to emit light, and the low potential of the light source driving signal can enable the light source to be extinguished; the larger the time parameter is, the longer the time T of the high potential is; the smaller the time parameter, the shorter the time T of the high potential. It should be noted that, when the operating mode set by the mode control circuit 120 is the stroboscopic mode, the light source controller 100 is configured to control the on-off time of the light source, and the amplitude of the light source driving signal can be adjusted according to actual requirements, for example: the amplitude of the light source driving signal may correspond to a maximum brightness level of the light source (i.e., the light source may emit a maximum brightness based on the light source driving signal); in addition, the high potential of the pwm signal may include the triangle wave (also called sawtooth wave or ripple).
