Description

Technical Field

[0001] The present invention relates to the technical field of xenon lamps, and more particularly to a xenon lamp high-pressure, high-temperature and strong-light protection system. Background Art

[0002] Xenon lamps are a common light source in spectral testing. This is because xenon lamps have a broad spectrum, covering the ultraviolet to near-infrared range, and can be used to simulate the solar spectrum, making them widely used in various spectral fields. However, when ignited, high-power xenon lamps require a transient high voltage of 20,000-40,000 volts to trigger the xenon gas discharge. This can cause irreversible damage to other components in instruments such as spectrometers. However, the operating voltage and current after ignition do not affect the operation of other components. Therefore, the startup and power supply of xenon lamps are specialized support systems. Once ignited, xenon lamps continuously generate high temperatures (approximately 200-300 degrees Celsius) and strong light, necessitating the design of a specialized protection system to minimize the impact of the xenon lamp on users and the environment.

[0003] Currently, to prevent the instantaneous high voltage generated by the xenon lamp from impacting other components of the instrument system, two separate power switches are often used for the xenon lamp system and the spectral master control system. These switches are manually controlled to power on the xenon lamp system and the master control system in sequence. This method is prone to human error and can damage the instrument due to the reversal of the power switch order. Furthermore, there is a lack of necessary avoidance and protection measures for the high temperatures and strong light generated during normal operation. Therefore, a new solution is needed to improve this. Summary of the Invention

[0004] The purpose of the present invention is to provide a xenon lamp high pressure, high temperature and strong light protection system, which solves the impact of the instantaneous high pressure when the xenon lamp is lit on other components of the instrument system. Usually, two different power switches are used for the xenon lamp system and the spectrum main control system, and they are powered on in sequence by manual control. This method is prone to human error and damage to the instrument due to the reversal of the order in which the different power switches are turned on. In addition, there is a lack of necessary avoidance and protection measures for the high temperature and strong light generated during normal operation, which meets the actual use needs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a xenon lamp high pressure, high temperature and strong light protection system, comprising:

[0006] The protection system connects two systems in parallel when the mains is turned on. One of the systems is connected to the xenon lamp switch power supply and trigger, lighting the xenon lamp and keeping it on during the working period of the spectral system. The xenon lamp is always on. The other system is connected to the AC filter and the time relay with a preset delay time. After the delay time, the switching power supply component that supplies power to the entire system is connected.

[0007] A time relay is connected between the switching power supply component and the AC filter, and the switching power supply component is grounded;

[0008] A micro switch is installed inside the xenon lamp, and the C port and NO port of the micro switch are connected to the xenon lamp switch power supply and the trigger respectively, wherein an absorption capacitor is also connected to the connection line between the micro switch and the trigger;

[0009] Xenon lamp, which is equipped with two protective mechanisms, one of which is a light shield cover and the other is a cooling fan;

[0010] The cooling fan starts with the system, forcing the heat generated by the xenon lamp to diffuse to the channel outside the system, reducing the impact of the high temperature generated by the xenon lamp on the system itself;

[0011] The light shield cover triggers the micro switch and is in the on state, and the xenon lamp is lit under the protection of the light shield, preventing all strong light from leaking out and affecting the user and the environment;

[0012] The V+ of the absorption capacitor and the NO end of the micro switch are respectively connected to the V+ end of the trigger, and the V- of the absorption capacitor, the V- 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.

[0013] As a preferred embodiment of the present invention, both systems are commonly grounded to avoid instantaneous high voltage shock of the xenon lamp caused by simultaneous power-on of both systems, and to avoid damaging the system connected to the other switching power supply through the common ground.

[0014] As a preferred embodiment of the present invention, the time relay is a multi-time period time relay.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention uses a time-sharing control method to automatically control the activation of the xenon lamp system and the spectrum control system, thereby preventing the impact of the approximately 30,000-volt high voltage on the spectrum control system during xenon lamp startup. The time-sharing period is pre-adjusted based on the energy level of the potential impact electrical signal generated by the monitored common ground, thus forming a universal time-sharing control method. Furthermore, certain protective technologies are implemented to reduce the impact of the high temperature and strong light generated by the normal operation of the xenon lamp on users, the environment, and the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 This is the electrical connection diagram of the xenon lamp high pressure, high temperature and strong light protection system of the present invention. DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 The present invention provides a technical solution: a xenon lamp high pressure, high temperature and strong light protection system, comprising:

[0020] The protection system connects two systems in parallel when the mains is turned on. One of the systems is connected to the xenon lamp switch power supply and trigger, lighting the xenon lamp and keeping it on during the working period of the spectral system. The xenon lamp is always on. The other system is connected to the AC filter and the time relay with a preset delay time. After the delay time, the switching power supply component that supplies power to the entire system is connected.

[0021] The time relay is connected between the switching power supply component and the AC filter, and the switching power supply component is grounded;

[0022] A micro switch is installed inside the xenon lamp, and the C port and NO port of the micro switch are connected to the xenon lamp switch power supply and the trigger respectively, wherein an absorption capacitor is also connected to the connection line between the micro switch and the trigger;

[0023] Xenon lamp, which is equipped with two protective mechanisms, one of which is a light shield cover and the other is a cooling fan;

[0024] By adjusting the delay relay and pre-delay period, the xenon lamp system is pre-energized, delaying the startup of the entire spectral system and achieving coordinated operation with the xenon lamp system. This prevents the impact of the xenon lamp's transient high voltage on the entire operating system. The delay time can also be pre-adjusted to meet the requirements of different systems. The linkage between the light shield and microswitch prevents the xenon lamp from turning on when the light is not blocked, preventing strong light leakage and environmental impact. The built-in cooling fan activates simultaneously at startup to continuously reduce the impact of high temperatures generated by the xenon lamp.

[0025] As a further improvement, both systems are commonly grounded to avoid instantaneous high-voltage shocks from the xenon lamp caused by powering both systems simultaneously, and to avoid damaging the system connected to the other switching power supply through the common ground, thereby protecting the circuit.

[0026] As a further improvement, the cooling fan starts along with the system, forcing the heat generated by the xenon lamp to diffuse to a channel outside the system, thereby reducing the impact of the high temperature generated by the xenon lamp when it is working on the system itself.

[0027] As a further improvement, the hood triggers the microswitch and turns it on, igniting the xenon lamp while protected by the hood, preventing the full leakage of strong light from impacting the user and the environment. Otherwise, the hood triggers the microswitch and turns it on, preventing the xenon lamp from being triggered and ignited while unprotected. This prevents the full leakage of strong light from impacting the user and the environment.

[0028] For further improvement, the V+ end of the absorption capacitor and the NO end of the micro switch are respectively connected to the V+ end of the trigger, and 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. The role played by the absorption capacitor in the circuit is similar to that of a low-pass filter, which can absorb the peak voltage and protect the safe operation of the system.

[0029] Specifically, the time relay is a multi-time period time relay, and different time periods can be set.

[0030] This invention replaces manual control with time-sharing control, mitigating the impact of instantaneous high voltage on the entire system during xenon lamp startup. Furthermore, the delay time of the time delay relay can be pre-adjusted based on the duration and intensity of interference signals appearing on the system's common ground. This effectively ensures that xenon lamp startup and the entire spectral system work in tandem, eliminating the potential for manual control errors.

[0031] The light shield's micro-switch mechanism uses a mechanical pressure block as a trigger. Whether the xenon lamp is powered on or off, installing the light shield (with the mechanical pressure block) effectively activates the xenon lamp's lighting circuit. If the light shield is not installed, the lamp will not light even if the power is on. This prevents the xenon lamp from being turned on when the light shield is not on, effectively protecting both the user and the environment from the effects of strong light.

[0032] The cooling fan starts as soon as the power is turned on, forcing air to be exhausted to the outside, so that the high temperature generated by the xenon lamp can be dissipated in time without causing damage to the entire working system.

[0033] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
