the xenon lamp is provided with two protection mechanisms, one of the protection mechanisms is a shading cover, and the other protection mechanism is a cooling fan;
the xenon lamp system is firstly powered on, the delayed start of the whole spectrum system is realized by adjusting the delay time relay and the pre-delay period, the xenon lamp system and the xenon lamp system achieve the purpose of coordinated work, and the impact of the xenon lamp instantaneous high-voltage system on the whole work system is avoided. The delay time may also be pre-adjusted to match the connection requirements of different systems. The linkage of the light shield and the micro switch can avoid that the xenon lamp cannot be started on the premise of no light shielding, and strong light is prevented from leaking and influencing the environment. The built-in heat dissipation fan is started at the same time, so that the high-temperature influence generated by the xenon lamp can be reduced all the time.
In a further improvement mode, the two systems are both in common grounding, instantaneous high-voltage impact of xenon lamps generated by simultaneous energization of the two systems is avoided, the other system connected with the switching power supply is damaged through the common grounding, and the circuit is protected.
In a further improvement mode, the heat dissipation fan is started along with the system, heat generated by the xenon lamp is forcibly diffused to a channel outside the system, and the influence of high temperature generated when the xenon lamp works on the system is reduced.
In a further improvement mode, the light-shielding cover triggers the micro switch and is in an on state, the xenon lamp is lightened under the protection state of the light-shielding cover, the influence of all strong light leakage on a user and the environment is avoided, the light-shielding cover triggers the micro switch to be in the on state, otherwise the xenon lamp cannot be triggered to be lightened, and the xenon lamp is prevented from being lightened under the unprotected state.

Specifically, the time relay is a time relay with multiple time periods, and different time periods can be set.
When the xenon lamp is used, manual control is replaced by time-sharing control, the impact of instantaneous high voltage on the whole system when the xenon lamp is started is solved, and the delay time of the delay time relay can be adjusted in advance according to the influence time and the strength of interference signals appearing in the common grounding of the system. The matching cooperative work of xenon lamp starting and the whole spectrum system is well solved. The possibility of misoperation of manual control is avoided.
