However, a high power xenon lamp requires a momentary high voltage of 2-4 ten thousand volts to trigger xenon discharge when lit. May cause irreversible damage to other components of instruments such as spectrometers. But the working voltage and current after the lighting of the LED lamp can not influence the working of other devices. Therefore, the starting and power supply of the xenon lamp are a special support system, and after the xenon lamp is lighted, high temperature (about 200-.
At present, in order to avoid the impact of the instantaneous high voltage generated by the lighting of the xenon lamp on other devices of an instrument system, two different power switches of the xenon lamp system and a spectrum main control system are often adopted, and the sequential electrification is implemented in a manual control mode, so that the mode easily causes artificial misoperation, the instrument is damaged due to the reversal of the starting sequence of the different power switches, and necessary evasion and protection measures are lacked for high temperature and strong light generated during the normal work of the instrument. For this reason, a new scheme needs to be designed to give improvements.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a xenon lamp high pressure, high temperature and glare protection system comprising:
the protection system is connected with two systems in parallel when the commercial power is connected, wherein one system is connected with a xenon lamp switching power supply and a trigger, the xenon lamp is lightened and kept in the working time period of the spectrum system, the xenon lamp is always lightened, the other system is connected with an alternating current filter and a time relay with preset delay time, and the switching power supply assembly for supplying power to the whole system is connected after the delay time;

the micro switch is arranged in the xenon lamp, a C port and an NO port of the micro switch are respectively connected with the xenon lamp switch power supply and the trigger, and an absorption capacitor is further connected to a connecting circuit of the micro switch and the trigger;
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. The influence of all strong light leakage on users and the environment is avoided.
In a further improvement mode, the V + end of the absorption capacitor and the NO end of the microswitch are respectively connected to the V + end of the trigger, the V-end of the absorption capacitor, the V-end of the xenon lamp switching power supply and the port of the xenon lamp are respectively connected to the V-/D-end of the trigger, and the absorption capacitor plays a role similar to a low-pass filter in a circuit, so that spike voltage can be absorbed, and the safe operation of a system is protected.
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.
A device for triggering micro-motion light opening by linkage of a light shield utilizes a mechanical press block as a trigger, the light shield (with the mechanical press block) is installed no matter the xenon lamp is not electrified or is electrified and lightened, a circuit for lightening the xenon lamp is actually switched on, and if the light shield is not installed, a power supply is switched on, and the xenon lamp cannot be lightened. The situation that the xenon lamp cannot be turned on under the condition of no shading is avoided. The problem that the user and the environment are possibly influenced by strong light is well protected.
The heat radiation fan which is started when the electricity is connected forcibly exhausts the air to the outside. The high temperature generated by the xenon lamp can be distributed in time, and the whole working system can not be damaged.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
