Description

Technical Field

[0001] This utility model relates to the field of ultraviolet-filtering quartz glass tubes, specifically an ultraviolet-filtering quartz glass tube for high-power xenon lamps. Background Technology

[0002] Xenon lamps are electric light sources that emit light by discharging xenon gas. Their radiation spectrum energy distribution is similar to that of sunlight, with a color temperature of approximately 6000K, providing people with lighting effects close to natural sunlight. The ultraviolet-filtering quartz glass tube is a key component specifically designed for high-power xenon lamps. It is a tubular structure made of quartz glass, doped with specific rare earth elements, giving the glass tube specific ultraviolet spectral absorption properties. This filters the light emitted by the xenon lamp, removing ultraviolet components and thus protecting users from ultraviolet damage.

[0003] High-power xenon lamps utilize ultraviolet-filtering quartz glass tubes to achieve their ultraviolet filtering function primarily through their internal ultraviolet-filtering layer. During the manufacturing process of the glass tube, specific rare earth elements are incorporated into the quartz glass material using a special process. These rare earth elements can interact with ultraviolet rays, absorbing their energy and thus reducing the intensity of ultraviolet radiation to a safe range. When the light emitted by the xenon lamp passes through the glass tube, the ultraviolet-filtering layer selectively absorbs the ultraviolet rays in the light, significantly reducing the ultraviolet content in the light that ultimately passes through the glass tube.

[0004] Xenon lamps are high-energy light sources that release a lot of heat during discharge. Due to the close contact between the UV-filtering quartz glass tube and the xenon lamp, the heat generated by the xenon lamp is conducted to the glass tube, causing the temperature of the UV-filtering quartz glass tube to rise. Furthermore, the internal structure of the UV-filtering quartz glass tube changes, resulting in a reduction in the UV filtering effect of the UV-filtering quartz glass tube. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-power xenon lamp UV filter quartz glass tube to solve the technical problem that the heat generated by the high-power xenon lamp during operation is conducted to the UV filter quartz glass tube, resulting in a reduction in the UV filtration effect of the UV filter quartz glass tube.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-power xenon lamp ultraviolet-filtering quartz glass tube, comprising an outer glass tube and a xenon lamp tube, wherein a second heat sink is provided at the top of the outer glass tube, a connector is installed at the bottom of the outer glass tube, and an electric contact piece is provided inside the connector, a base is connected to the bottom of the outer glass tube, and a connecting tube is fixed at the top of the base, a xenon lamp tube is installed inside the outer glass tube, and a first heat sink is provided at the top of the xenon lamp tube, wherein multiple sets of heat-conducting columns are fixed to the outer wall of the first heat sink, and the ends of the heat-conducting columns are connected to the inner wall of the second heat sink.

[0007] By adopting the above technical solution, the technical problem of heat generated during the operation of a high-power xenon lamp being conducted to the ultraviolet-filtering quartz glass tube, resulting in a reduction in the filtration effect of the ultraviolet light by the ultraviolet-filtering quartz glass tube, is solved. After the outer glass tube is energized, the electrodes excite the xenon gas in the inner cavity, causing the xenon gas to emit strong light. The strong light is projected out of the xenon lamp tube. When the strong light is projected onto the outer glass tube, the ultraviolet-filtering layer in the outer glass tube filters out the ultraviolet light contained in the strong light. During the discharge process of the xenon lamp tube, a large amount of heat is generated inside, causing the temperature on the outer wall of the xenon lamp tube to rise. When the temperature of the xenon lamp tube rises, the first heat sink, which is in close contact with the xenon lamp tube, conducts the heat on the xenon lamp tube to the second heat sink through the heat conduction column. The second heat sink dissipates the heat generated by the xenon lamp tube into the air, thereby reducing the temperature of the xenon lamp tube under high power conditions.

[0008] The present invention is further configured such that the xenon lamp tube has an inner cavity inside, and the inner cavity is filled with the rare gas xenon.

[0009] By adopting the above technical solution, the rare gas xenon is filled into the inner cavity of the xenon lamp tube. When the xenon is excited by the high voltage current of the two sets of electrodes, the xenon emits strong light.

[0010] The present invention is further configured such that two sets of conductive pillars are installed inside the inner cavity, and an electrode is fixed at the end of one set of conductive pillars.

[0011] By adopting the above technical solution, two sets of conductive pillars deliver high-voltage current to the electrodes, forming a high-voltage arc between the two sets of electrodes. The high-voltage arc excites the rare gas xenon inside the cavity, causing the xenon to ionize and form electrons, thereby making the xenon emit strong light.

[0012] The present invention is further configured such that a vacuum chamber is provided inside the outer glass tube, and no substance is conducted inside the vacuum chamber.

[0013] By adopting the above technical solution, the heat generated by the electrodes inside the xenon lamp tube causes the overall temperature of the xenon lamp tube to rise. A vacuum chamber is set inside the glass outer tube, so that the heat inside the xenon lamp tube will not be conducted to the glass outer tube.

[0014] The present invention is further configured such that a protective cover is connected to the outer wall of the second heat sink, and the protective cover is made of polycarbonate material.

[0015] By adopting the above technical solution, polycarbonate material has good heat insulation function, which can protect personnel from being burned when they come into contact with the protective cover installed on the second heat dissipation cover.

[0016] The present invention is further provided that the outer wall of the protective cover is provided with a vent hole, and the vent hole can allow the interior of the protective cover to communicate with the outside air.

[0017] By adopting the above technical solution, the second heat dissipation cover inside the protective cover conducts heat to the outside air through the vents, thereby increasing the heat dissipation effect of the second heat dissipation cover.

[0018] The present invention is further provided that the inner side of the glass outer tube is provided with a protective layer, and the protective layer is made of quartz fiber composite material.

[0019] By adopting the above technical solution, the protective layer made of quartz fiber composite material has good heat insulation performance. The protective layer isolates the heat on the second heat dissipation cover and prevents the heat on the second heat dissipation cover from affecting the ultraviolet filter layer in the outer glass tube.

[0020] The present invention is further configured such that an ultraviolet filter layer is provided inside the glass outer tube, and the ultraviolet filter layer filters the ultraviolet light emitted from the xenon lamp tube.

[0021] By adopting the above technical solution, the strong light emitted by the xenon lamp tube contains a large amount of ultraviolet light. The ultraviolet filter layer in the outer glass tube filters out the ultraviolet light in the strong light, preventing excessive ultraviolet light from causing harm to people.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the technical problem that the heat generated by a high-power xenon lamp during operation is conducted to the ultraviolet-filtering quartz glass tube, which reduces the filtering effect of the ultraviolet light. This is achieved by setting up a glass outer tube, a xenon lamp tube, a first heat sink, a heat-conducting column, and a second heat sink. When the glass outer tube is energized, the electrodes excite the xenon gas in the inner cavity, causing the xenon gas to emit strong light. The strong light is projected out of the xenon lamp tube. When the strong light is projected onto the glass outer tube, the ultraviolet-filtering layer in the glass outer tube filters out the ultraviolet light contained in the strong light. During the discharge process of the xenon lamp tube, a large amount of heat is generated inside, causing the temperature on the outer wall of the xenon lamp tube to rise. When the temperature of the xenon lamp tube rises, the first heat sink, which is in close contact with the xenon lamp tube, conducts the heat on the xenon lamp tube to the second heat sink through the heat-conducting column. The second heat sink dissipates the heat generated by the xenon lamp tube into the air, thereby reducing the temperature of the xenon lamp tube under high power conditions.

[0024] 2. This utility model, by setting up a protective cover, a vent, and a vacuum chamber, isolates the heat generated by the xenon lamp tube inside the glass outer tube, preventing the heat from the xenon lamp tube from being conducted to the glass outer tube and avoiding the situation of the glass outer tube burning people. In addition, the protective cover is installed on the outer wall of the second heat sink, which exchanges heat with the outside air through the vent. At the same time, the protective cover can also protect people from being burned by the second heat sink. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] A high-power xenon lamp uses a UV-filtering quartz glass tube, such as Figure 1 - Figure 5 As shown, the device includes a glass outer tube 1 and a xenon lamp tube 2. A second heat sink 302 is installed on the top of the glass outer tube 1, and a connector 102 is installed at the bottom of the glass outer tube 1. An electric contact piece 103 is installed inside the connector 102. A base 6 is connected to the bottom of the glass outer tube 1, and a connecting pipe 601 is fixed to the top of the base 6. The xenon lamp tube 2 is installed inside the glass outer tube 1, and a first heat sink 3 is installed on the top of the xenon lamp tube 2. Multiple sets of heat-conducting columns 301 are fixed to the outer wall of the first heat sink 3, and the ends of the heat-conducting columns 301 are connected to the inner wall of the second heat sink 302. This design solves the technical problem of heat generated by a high-power xenon lamp being conducted to the ultraviolet-filtering quartz glass tube, which reduces the filtration efficiency of the ultraviolet light filtering quartz glass tube. When the glass outer tube 1 is energized, the electrode 4 excites the xenon gas 202 in the inner cavity 201, causing the xenon gas 202 to emit strong light. The strong light is projected onto the xenon lamp tube 2. When the strong light is projected onto the glass outer tube 1, the ultraviolet filter layer 120 in the glass outer tube 1 filters out the ultraviolet light contained in the strong light. During the discharge process of the xenon lamp tube 2, a large amount of heat is generated inside, causing the temperature on the outer wall of the xenon lamp tube 2 to rise. When the temperature of the xenon lamp tube 2 rises, the first heat sink 3, which is in close contact with the xenon lamp tube 2, conducts the heat on the xenon lamp tube 2 to the second heat sink 302 through the heat conduction column 301. The second heat sink 302 dissipates the heat generated by the xenon lamp tube 2 into the air, thereby reducing the temperature of the xenon lamp tube 2 under high power conditions.

[0034] Please see Figure 4 The xenon lamp tube 2 has an inner cavity 201 inside, which is filled with rare xenon gas 202. When the rare xenon gas 202 is filled into the inner cavity 201 inside the xenon lamp tube 2, the xenon gas 202 emits strong light after being excited by the high voltage current of the two sets of electrodes 4.

[0035] Please see Figure 4 The inner cavity 201 has two sets of conductive pillars 401 installed inside, and an electrode 4 is fixed at the end of one set of conductive pillars 401. The two sets of conductive pillars 401 deliver high voltage current to the electrode 4, and a high voltage arc is formed between the two sets of electrodes 4. The high voltage arc excites the rare gas xenon 202 inside the inner cavity 201, causing the xenon 202 to ionize and form electrons, thereby making the xenon 202 emit strong light.

[0036] Please see Figure 3 The glass outer tube 1 has a vacuum chamber 101 inside, and no substance is conducted inside the vacuum chamber 101. The heat generated by the electrode 4 inside the xenon lamp tube 2 causes the overall temperature of the xenon lamp tube 2 to rise. The vacuum chamber 101 inside the glass outer tube 1 prevents the heat inside the xenon lamp tube 2 from being conducted to the glass outer tube 1.

[0037] Please see Figure 1 The outer wall of the second heat sink 302 is connected to a protective cover 5, and the protective cover 5 is made of polycarbonate material. Polycarbonate material has good heat insulation function, so that the protective cover 5 installed on the second heat sink 302 can protect personnel from being burned when they come into contact with the protective cover 5.

[0038] Please see Figure 1 The outer wall of the protective cover 5 is provided with a vent 501, which allows the interior of the protective cover 5 to communicate with the outside air. The second heat dissipation cover 302 inside the protective cover 5 conducts heat with the outside air through the vent 501, thereby increasing the heat dissipation effect of the second heat dissipation cover 302.

[0039] Please see Figure 5 The glass outer tube 1 is provided with a protective layer 110, and the protective layer 110 is made of quartz fiber composite material. The protective layer 110 made of quartz fiber composite material has good heat insulation performance. The protective layer 110 isolates the heat on the second heat dissipation cover 302 and prevents the heat on the second heat dissipation cover 302 from affecting the ultraviolet filter layer 120 in the glass outer tube 1.

[0040] Please see Figure 5 The glass outer tube 1 is equipped with an ultraviolet filter layer 120, which filters the ultraviolet light emitted from the xenon lamp tube 2. The strong light emitted by the xenon lamp tube 2 contains a large amount of ultraviolet light. The ultraviolet filter layer 120 in the glass outer tube 1 filters out the ultraviolet light in the strong light to prevent excessive ultraviolet light from causing harm to people.

[0041] The working principle of this utility model is as follows: First, the connector 102 at the bottom of the glass lamp tube 1 is fixedly connected to the connector 601 at the top of the base 6 by threads. At the same time, the wire in the base 6 is in contact with the contact piece 103 to conduct electricity. After the glass outer tube 1 is energized, the electrode 4 excites the xenon gas 202 in the inner cavity 201, causing the xenon gas 202 to emit strong light. The strong light is projected out of the xenon lamp tube 2. When the strong light is projected onto the glass outer tube 1, the ultraviolet filter layer 120 in the glass outer tube 1 filters out the ultraviolet light contained in the strong light. During the discharge process of the xenon lamp tube 2, a large amount of heat is generated inside it. The heat generated by the xenon lamp tube 2 causes the temperature on the outer wall of the xenon lamp tube 2 to rise. When the temperature of the xenon lamp tube 2 rises, the first heat sink 3, which is in close contact with the xenon lamp tube 2, will conduct the heat on the xenon lamp tube 2 to the second heat sink 302 through the heat conduction column 301. The second heat sink 302 dissipates the heat generated by the xenon lamp tube 2 into the air, thereby reducing the temperature of the xenon lamp tube 2 when it is in a high-power state. At the same time, the vacuum cavity 101 set inside the glass outer tube 1 isolates the heat generated by the xenon lamp tube 2, preventing the heat on the xenon lamp tube 2 from being conducted to the glass outer tube 1, thus avoiding the situation where the glass outer tube 1 burns people.
