Description

Technical Field

[0001] This application relates to the field of gas lamp detection technology, and in particular to a gas discharge lamp detection system. Background Technology

[0002] Lighting is an indispensable infrastructure in modern society, and developing efficient, long-life, and environmentally friendly lighting sources has always been a continuous pursuit in this field. Gas discharge lamps, as an important type of light source, emit light by filling a sealed discharge tube with a specific gas, metal vapor, or a mixture thereof, and applying a voltage between the electrodes at both ends. This ionizes the gas to form plasma, which then emits photons through the transition of excited states of atoms or molecules to their ground states. Depending on the filling material and structure, gas discharge lamps can be classified into various types, such as high-pressure sodium lamps, metal halide lamps, low-pressure sodium lamps, and various xenon and neon lamps.

[0003] The composition and pressure of the gas inside a gas discharge lamp directly affect its spectral characteristics. However, the existing detection method involves disassembling the gas discharge lamp to detect the gas inside. This method is not only prone to gas leakage and pollution, but also affects the accuracy of the detection. At the same time, the disassembly process is also dangerous and requires a certain level of skill and patience from the personnel. Utility Model Content

[0004] In view of the problems existing in the background technology, this application provides a gas discharge lamp detection system that can efficiently, accurately and easily detect the gas composition and pressure of gas discharge lamps.

The gas discharge lamp to be tested is then installed in a second dark chamber, and a second high-voltage exciter applies a high voltage to the gas discharge lamp to cause it to discharge, thereby generating light.

This method can efficiently, accurately, and easily detect the gas composition and pressure of gas discharge lamps without breaking the gas discharge lamp.

[0025] The gas discharge lamp detection system provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0026] This application discloses a gas discharge lamp detection system. For example... Figure 1 and Figure 3 As shown, the gas discharge lamp detection system includes a calibration device and a detection device. The calibration device includes a first dark box 1, a gas pipeline 2, a vacuum system 3, an anode and cathode assembly, a first high-voltage exciter 4, and a first spectrometer. The detection device includes a second dark box 5, a second high-voltage exciter 6, and a second spectrometer.

[0027] A closed chamber is formed inside the first dark box 1. A gas pipe 2 is connected to the first dark box 1 and communicates with the closed chamber. By connecting the gas pipe 2 to an external gas source, a calibration gas equivalent to the gas in the gas discharge lamp 9 to be tested can be filled into the closed chamber. A vacuum system 3 is connected to the first dark box 1 and communicates with the closed chamber. Before filling the closed chamber with gas using the gas pipe 2, the ordinary gas in the closed chamber can be discharged through the vacuum system 3 to ensure the purity of the calibration gas remaining in the closed chamber. An anode and cathode assembly is located on the first dark box 1 and extends into the closed chamber. A first high-voltage exciter 4 is located outside the first dark box 1 and connected to the anode and cathode assembly. Using the first high-voltage exciter 4, a high voltage can be applied to the calibration gas in the closed chamber through the anode and cathode assembly, inducing the calibration gas to discharge and thus generate light. The first dark box 1 is equipped with a first optical interface 7. A first spectrometer is located outside the first dark box 1 and can be connected to the first optical interface 7. When the calibration gas in the closed chamber discharges and generates light, the first spectrometer can collect the light spectrum and detect its spectral characteristics.

[0028] The second dark box 5 forms an installation chamber for mounting the gas discharge lamp 9 to be tested. A second high-voltage exciter 6 is located outside the second dark box 5 and is used to connect to the anode and cathode of the gas discharge lamp 9. Using the second high-voltage exciter 6, a high voltage can be applied to the gas being tested inside the gas discharge lamp 9, causing the lamp to discharge and thus produce light. The second dark box 5 is equipped with a second optical interface 8. A second spectrometer is located outside the second dark box 5 and can be connected to the second optical interface 8. When the gas discharge lamp 9 discharges and produces light, the second spectrometer can collect the light spectrum and detect its spectral characteristics.

[0029] By using the gas discharge lamp detection system in this technical solution, various calibration gases are first prepared based on the same gas composition but different proportions and pressure differences in the same type of gas discharge lamp 9, or different gas compositions, proportions, and pressure differences in different gas discharge lamps 9. After the ordinary gas in the sealed chamber is extracted using the vacuum system 3, a calibration gas is simultaneously introduced into the sealed chamber through the gas pipe 2. A high voltage is applied to the calibration gas in the sealed chamber using the first high-voltage exciter 4 through the anode and cathode assembly, inducing the calibration gas to discharge and generate light. The light spectrum is then collected by the first spectrometer, and the spectral characteristics are detected. This process is repeated one by one. Each calibration gas is tested to obtain the correspondence between spectral data and gas ratio and pressure, and a characteristic curve is plotted. Then, the gas discharge lamp 9 to be tested is installed in the second dark box 5, and a high voltage is applied to the gas discharge lamp 9 using the second high voltage exciter 6 to cause the gas discharge lamp 9 to discharge, thereby generating light. The light spectrum is then collected by the second spectrometer, and the spectral characteristics are detected. The spectral data of the gas discharge under test is compared with the characteristic curve to find the corresponding gas ratio and pressure value. Without breaking the gas discharge lamp 9, the gas composition and pressure of the gas discharge lamp 9 can be detected efficiently, accurately and easily.

[0030] In some embodiments of this utility model, the first spectrometer and the second spectrometer are the same spectrometer.

[0031] It should be understood that when performing calibration gas spectral detection, the spectrometer is connected to the first dark box 1 through the first optical interface 7. Then, when performing gas discharge lamp 9 spectral detection, the same spectrometer is removed from the first dark box 1 and connected to the second dark box 5 through the second optical interface 8.

[0032] In this embodiment, for the spectral detection of the calibration gas and the gas discharge lamp 9, by using the same equipment, the error introduced by the detection instrument can be effectively eliminated, ensuring the consistency of the spectral detection. Thus, when the spectral data of the gas discharge under test is compared with the characteristic curve, the accurate gas ratio and pressure value can be obtained, ensuring the accuracy of the detection.

[0033] In some embodiments of this utility model, such as Figure 1-4 As shown, the spectrometer includes a fiber optic spectrometer 10 and an imaging spectrometer 11.

[0034] It should be understood that in this embodiment, the spectrometers used include a fiber optic spectrometer 10 and an imaging spectrometer 11, and the fiber optic spectrometer 10 and the imaging spectrometer 11 are used separately. When performing calibration gas spectral detection, the fiber optic spectrometer 10 can be used to collect spectral data of local locations in the closed chamber during discharge, such as through a fiber optic probe. The imaging spectrometer 11 can be used to collect the overall spectral data of the closed chamber during discharge. According to the location of the closed chamber, such as the end of the anode and cathode group, between the anode and cathode of the anode and cathode group, or both sides, the spectral data and the correspondence between the gas ratio and pressure are recorded and plotted as characteristic curves. When performing spectral detection of the gas discharge lamp 9, the fiber optic spectrometer 10 can be used to collect spectral data of local locations in the gas discharge lamp 9 during discharge, and the imaging spectrometer 11 can be used to collect the overall spectral data of the gas discharge lamp 9 during discharge. According to the locations of the anode and cathode ends of the lamp, between the anode and cathode, and both sides of the anode and cathode, the spectral data are recorded separately. By comparing them separately, the accuracy of the detection can be further improved.

[0035] In some embodiments of this utility model, such as Figure 1 As shown, the anode and cathode assembly includes an anode 12 and a cathode 13, which are spaced apart in a closed chamber, with the area between the anode 12 and the cathode 13 located in the middle of the closed chamber.

[0036] In this embodiment, by placing the anode and cathode assembly in the middle of the enclosed chamber, the uniformity of the high voltage applied to the calibration gas by the first high-voltage exciter 4 can be improved, and the gas discharge lamp 9 can be better simulated, so that the light produced by the calibration gas and the light produced by the gas discharge lamp 9 can be relatively consistent.

[0037] In some embodiments of this utility model, such as Figure 1 As shown, the first dark box 1 is equipped with an observation window 14.

[0038] In this embodiment, during the calibration gas discharge emission, the conditions inside the closed chamber can be observed in advance through the observation window 14 to ensure the smooth progress of the calibration test.

[0039] Furthermore, observation window 14 corresponds to the anode and cathode group.

[0040] Preferably, the observation window 14 is an openable observation window 14, that is, an opening is made in the first dark box 1 and a transparent part is installed inside the opening to close the opening. A non-transparent baffle is used on the outside to block the transparent part, which can be opened or closed. After the observation is completed through the transparent part, the non-transparent baffle is used to block the transparent part to prevent external light from entering the first dark box 1 and affecting the test results.

[0041] In some embodiments of this utility model, such as Figure 1 As shown, a first valve 15 is installed on the gas pipeline 2.

[0042] In this embodiment, after the calibration gas from the gas source is filled into the closed chamber through the gas pipeline 2, the gas pipeline 2 can be closed immediately by the first valve 15 to ensure that the composition, ratio and pressure of the calibration gas in the closed chamber are stable.

[0043] Furthermore, the first valve 15 is a one-way valve. The one-way valve connects the gas pipeline 2 to the first dark chamber 1 from the end away from the first dark chamber 1, preventing the calibration gas filled into the closed chamber from flowing back, and allowing the required volume of calibration gas to be filled into the closed chamber in a more controllable manner.

[0044] Preferably, the first valve 15 is an integrated structure of a check valve and an on / off valve, which can be closed when needed, such as when using the vacuum system 3 to discharge gas from the closed chamber.

[0045] In some embodiments of this utility model, the gas pipeline 2 is provided with multiple pipelines.

[0046] It should be noted that the number of gas pipelines 2 can be two, three, or four, and each gas pipeline 2 can be equipped with a first valve 15.

[0047] In this embodiment, depending on the different quantities of gas components in different gas discharge lamps 9, different gas sources can be connected to the closed chamber through gas pipes 2, and then the corresponding gases can be filled into the closed chamber to form a mixed gas, which constitutes the calibration gas equivalent to the gas discharge lamp 9.

[0048] In some embodiments of this utility model, a second valve (not shown) is provided between the vacuum system 3 and the first dark box 1.

[0049] In this embodiment, after the ordinary gas or the calibration gas from the previous test is fully discharged from the sealed chamber using the vacuum system 3, the second valve can be used to disconnect the sealed chamber from the outside world to prevent the reintroduction of impurity gas into the sealed chamber.

[0050] In some embodiments of this utility model, a pressure gauge (not shown) for detecting the air pressure inside the closed chamber can also be installed on the first dark box 1, and the pressure gauge can be disconnected from the closed chamber through a valve.

[0051] In some embodiments of this utility model, a lamp holder can be installed in the mounting chamber of the second dark box 5, and the positive and negative electrodes of the lamp holder can be led out to the outside of the second dark box 5 through leads and connected to the second high-voltage exciter 6. The second dark box 5 is provided with an openable door (not shown) so that the door can be opened to connect the gas discharge lamp 9 to be tested to the lamp holder for subsequent spectral detection.

[0052] In some embodiments of this utility model, the vacuum system 3 can be a vacuum pump connected to the first dark box 1 via a pipeline.

[0053] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
