If the standby operation is performed/the input light intensity value is 0 operation/the standby operation is executed and the input light intensity value is executed If the intensity is 0, go to step S62; if not, go to step S7; Step S62: the main control chip controls the main LED driver to turn off the main LED light, and the main control chip controls the spare LED light driver to turn off the spare LED light at the same time, and executes step S6. 8. The method for the automatic switching system of the cold light source backup lamp of medical endoscope according to claim 7, characterized in that, after starting the main LED lamp or the backup LED lamp, it also includes judging the light intensity, specifically comprising the following steps: Step s1: The main control chip controls the main LED driver to turn off the main LED light, the main control chip controls the spare LED light driver to turn off the spare LED light, and the main control chip controls the stepping motor driver to drive the stepping motor at the same time, driving the mirror turntable to reset to vertical direction; Step s2: The main LED temperature sensor reads the temperature of the main LED light in real time and feeds it back to the main control chip; Step S21: The main control chip judges whether the user performs a standby operation or whether the user adjusts the light intensity value to 0. If the standby operation is performed/the input light intensity value is 0 operation/the standby operation is executed and the input light intensity value is executed If the intensity is 0, go to step S22; if not, go to step s3; Step S22: the main control chip controls the main LED driver to turn off the main LED light, and the main control chip simultaneously controls the spare LED light driver to turn off the spare LED light, and executes step s2; Step s3: The main control chip judges whether the temperature of the main LED lamp is greater than the set temperature upper limit, if no, execute step s4-step s6, if yes, execute step s7-step s12; Step s4: the main control chip controls the main LED driver to turn on the main LED light, and the main LED light directly outputs light through the output port; Step s5: The light intensity detector detects the light intensity value of the light signal at the output port in real time and feeds it back to the main control chip; Step s6: The main control chip judges whether the light intensity value of the main LED lamp is equal to 0, if no, go to step s2, if yes, go to step s7-step s12; Step s7: The main control chip controls the main LED driver to turn off the main LED light, the main control chip controls the spare LED light driver to turn off the spare LED light, and the main control chip controls the stepping motor driver to drive the stepping motor at the same time, driving the mirror turntable to rotate to the horizontal direction ; Step s8: The standby LED temperature sensor reads the temperature of the standby LED lamp in real time, and feeds back to the main control chip; Step S61: The main control chip judges whether the user performs a standby operation or whether the user adjusts the light intensity value to 0. If the standby operation is performed/the input light intensity value is 0 operation/the standby operation is executed and the input light intensity value is executed If the intensity is 0, go to step S62; if not, go to step s9; Step S62: the main control chip controls the main LED driver to turn off the main LED light, and the main control chip controls the spare LED light driver to turn off the spare LED light at the same time, and executes step s8; Step s9: The main control chip judges whether the temperature of the standby LED lamp is greater than the set temperature upper limit, if no, execute step s10-step s12, if yes, execute step s1; Step s10: the main control chip controls the driver of the spare LED light to turn on the spare LED light, and the output light of the spare LED light is reflected to the light outlet through the reflector turntable for output; Step s11: the light intensity detector detects the light intensity value of the light signal at the output port in real time and feeds it back to the main control chip; Step s12: the main control chip judges whether the light intensity value of the standby LED light is equal to 0, if no, go to step s8, if yes, go to step s1.
