Description

Technical Field

[0001] The invention belongs to the field of ultraviolet lamp tubes, and in particular relates to a lamp tube with a conductive connecting end. Background Art

[0002] The ultraviolet lamp is a gas-filled quartz tube. The gas produces discharge under the action of AC voltage, the gas molecules undergo energy level transition, and the energy is released, thereby generating ultraviolet radiation. Existing ultraviolet lamps can be used in ultraviolet irradiation equipment, for example: for ultraviolet light treatment of surface coatings of materials (such as fibers, glass, metals, etc.) to achieve curing treatment or decolorization and color change treatment of the surface coatings of the materials. At present, two electrodes are usually set in the quartz tube in the ultraviolet tube. The ultraviolet light will change during the discharge process, and the discharge will be uneven, and the energy distribution of the lamp tube will be uneven. Because the ultraviolet energy density of the lamp tube is locally high, it causes local overheating, the surface of the glass tube turns black, and the ultraviolet energy decays, resulting in a short life. This limits the application of ultraviolet tubes in different specifications, especially the application of long lamps and high power of ultraviolet tubes. Summary of the invention

[0013] The embodiments of the present invention are further described below in conjunction with the accompanying drawings: Depend on Figure 1 Combination Figure 2-Figure 6 As shown, a lamp tube with a conductive connecting end includes a glass tube 1 and further includes: An electrode group is provided at both ends of the glass tube 1 and is used to be connected to a power source; the electrode group comprises a first electrode 2 and a second electrode 3; The mounting member 4 is arranged in the glass tube 1, and divides the space in the glass tube 1, and each divided space of the glass tube 1 is provided with working gas; specifically, the glass tube is a quartz glass tube. More specifically, the conductive connecting end is fixed on the mounting member; The conductive connecting end is fixed on the mounting member 4. The conductive connecting end is arranged between the first electrode 2 and the second electrode 3. The conductive connecting end includes a first conductive member 5 and a second conductive member 6. The first conductive member 5 is arranged toward the first electrode 2, and the second conductive member 6 is arranged toward the second electrode 3. The first electrode 2, the first conductive member 5, the second conductive member 6, and the second electrode 3 are in the same straight line. The current at the first electrode 2 passes through the working gas, the conductive connecting end, the working gas, and the second electrode to form a loop and make the lamp work. The beneficial effect of the present invention is that a conductive connecting end is provided, and a mounting member is provided on the glass tube, so that the conductive connecting end is conveniently installed in the glass tube. The mounting member and the conductive connecting end are provided to separate the space in the glass tube and the discharge interval. The setting of the conductive connecting end optimizes the conductivity of the gas discharge, makes the discharge more stable, and generates ultraviolet energy distribution in different intervals, and the ultraviolet energy distribution is uniform. The present invention also has the advantages of simple structure, convenient assembly, reliable operation, and long service life. The first electrode 2, the first conductive member 5, the second conductive member 6 and the second electrode 3 are on the same straight line, which facilitates discharge and enables the working gas to work. The present invention is particularly suitable for ultraviolet lamps.

[0014] The mounting member 4 is a conductive member, and the first conductive member 5 and the second conductive member 6 are electrically connected through the mounting member 4. Taking a single conductive connection end as an example, it is usually arranged in the middle of the glass tube, so that the discharge is divided into sections, and the discharge effect is better, so that the lamp can work normally and output stable energy in a high power density environment of the ultraviolet tube. Generally speaking, the first conductive member and the second conductive member are both arranged in the middle of the glass tube. With such a structure, when the lamp tube is working, the discharge is divided into two sections, the discharge is stable, the structure is compact, and it is easy to install and use.

[0015] The mounting part 4 is sealed with the quartz glass tube by flame melting. After the quartz glass tube is formed, it supports the intermediate mounting part. The first conductive part 5 and the second conductive part 6 are respectively welded to the mounting part to achieve electrical conduction. The first conductive part 5 and the second conductive part 6 connect the discharge arc during operation, stabilize the discharge, and increase the discharge continuity stability. The discharge uniformity is improved. Taking the lamp model JSC-19320 as an example, the lamps with and without conductive connecting ends were tested at the customer site. The test results are shown in the attached Figure 5 , 6 , where uniformity means that a batch of substances or samples have the same properties or characteristics in all parts; UV lamps with conductive connecting ends can continuously and stably output discharge, the lamps work stably, and the radiation uniformity is greatly improved.

[0016] There are multiple conductive connecting ends, and each conductive connecting end is fixed on a corresponding mounting member 4. Each mounting member 4 divides the space in the glass tube 1 into different spaces, and each space divided into glass tubes is provided with the working gas. Of course, in practice, the two spaces separated by the mounting members can also be relatively connected. Specifically, the first conductive members 5 in different conductive connecting ends face the same direction, and the working gas is provided between the first conductive member 5 and the second conductive member 6 of the other adjacent conductive connecting ends, and current flows between the first conductive member 5, the working gas, and the second conductive member 6 of the other adjacent conductive connecting ends, so that the lamp tube works. When there are multiple groups of conductive connecting ends, the glass tubes are usually separated by the conductive connecting ends. With such a structure, when the lamp tube works, the discharge is divided into multiple sections, the discharge is stable, the structure is compact, and it is easy to install and use. In this way, the product can be applied to high-power long lamp tubes, so that the product discharges evenly and the energy of the lamp tube is distributed, so as to avoid the ultraviolet energy density of the lamp tube being too concentrated in a local area.

[0017] The distance between the conductive connecting end and the first electrode 2 and / or the second electrode 3 is adjustable to achieve reasonable distribution of the energy of the lamp tube, so that the energy distribution of the lamp tube can be uniform according to needs and application scenarios, avoiding the concentration of ultraviolet energy density of the lamp tube.

[0018] The two ends of the glass tube 1 are melted and provided with a ceramic lamp cap 7. Specifically, it also includes a connecting piece 8, and the ceramic lamp cap 7 is provided with a receiving groove 71. The connecting piece 8 is inserted into the receiving groove 71 and bonded to the ceramic lamp cap 7 through a ceramic adhesive. Specifically, the electrode group is provided with a lead wire for easy connection, and the lead wire is connected to the wire 9 or the metal contact, and the ceramic lamp cap 7 is provided with a lead hole 72 for the wire 9 or the metal contact to pass through. The lamp cap made of ceramic material can withstand high temperature, play the role of electrical insulation, support the lamp tube and position the lamp tube, and is easy to be installed in the shell for overall assembly and use, and has high safety. The setting of the receiving groove makes the lamp tube connection convenient and reliable.

[0019] The glass tube 1, the mounting member 4, the conductive connecting end and the connecting member 8 are an integrated structure, which is convenient for product production and processing, and has a simple and compact structure.

[0020] The glass tube 1 is filled with working gas with a pressure lower than one atmosphere, and the electrode group discharges and generates a discharge current through the conductive connecting end to make the working gas generate ultraviolet rays, and the lamp works. In this way, the product has high ultraviolet energy, long life and high safety.
