Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ultraviolet lamps, in particular to an excimer lamp. Background Art
[0002] Excimer lamps use high pressure and high frequency outside the lamp tube to bombard the rare gas inside the lamp tube to emit ultraviolet rays. Compared with low-pressure mercury lamps, the discharge tube of excimer lamps is not filled with harmful substances such as mercury, and has no negative impact on the environment. They are widely used in medical, water treatment, environmental protection, chemical, material surface treatment and other industries. However, the lamp tube of existing excimer lamps is generally a round tube. When the excimer lamp emits light, the light scatters around the lamp tube. When the object to be irradiated is located on one side of the lamp tube, the light emitted from the lamp tube is relatively scattered, so the irradiation effect of the excimer lamp on the object to be irradiated is not good.

[0004] In order to solve the above technical problems, the utility model provides a quasi-molecular lamp, including a lamp tube, a first electrode and a second electrode, the interior of the lamp tube is provided with a sealed cavity, the sealed cavity is filled with a dischargeable gas, the side wall of the lamp tube includes an arcuate side wall and a flat side wall, one side of the arcuate side wall is connected to one side of the flat side wall, the arcuate side wall is connected to the flat side wall in an arch shape, the first electrode is fittedly arranged on the outer side of the arcuate side wall, the second electrode is fittedly arranged on the outer side of the flat side wall, the first electrode and the second electrode are arranged opposite to each other, the distance between the end of the first electrode and the end of the second electrode is greater than the first distance, and the first distance is the minimum safety distance required between the first electrode and the second electrode.
[0005] As a preferred solution of the utility model, a chamfer is provided at the connection between the arc-shaped side wall and the flat side wall.
[0006] As a preferred solution of the utility model, the connection between the arc-shaped side wall and the flat side wall is covered with an insulating protective pad.
[0007] As a preferred solution of the present utility model, the first electrode is one of a metal block, a metal sheet, a metal mesh and a conductive film.

[0018] like Figure 1-3As shown, a preferred embodiment of the utility model is an excimer lamp, comprising a lamp tube 1, a first electrode 2 and a second electrode 3. A sealed cavity 11 is provided inside the lamp tube 1, and the sealed cavity 11 is filled with a dischargeable gas. The side wall of the lamp tube 1 comprises an arcuate side wall 12 and a flat side wall 13. The arcuate side wall 12 is in the shape of a cylinder with a fan-shaped cross section, and the flat side wall is in the shape of a cylinder with a rectangular cross section. The arcuate side wall 12 is connected to the flat side wall 13 in an arch shape, that is, one end of the arcuate side wall 12 is connected to one end of the flat side wall 13, and the other end of the arcuate side wall 12 is connected to the other end of the flat side wall 13. The cross section of the side wall of the lamp tube 1 is arched, and the first electrode 2 is arranged on the outer side of the arcuate side wall 12 in a close fit. The outer side of the arc-shaped side wall 12 refers to the side of the arc-shaped side wall 12 away from the inside of the lamp tube 1, the shape of the side of the first electrode 2 close to the arc-shaped side wall 12 is consistent with the shape of the outer side of the arc-shaped side wall 12, the second electrode 3 is fittedly arranged on the outer side of the flat side wall 13, the outer side of the flat side wall 13 refers to the side of the arc-shaped side wall 12 away from the inside of the lamp tube 1, the shape of the side of the second electrode 3 close to the flat side wall 13 is consistent with the shape of the outer side of the flat side wall 13, the first electrode 2 and the second electrode 3 are arranged opposite to each other, the distance between the end of the first electrode 2 and the end of the second electrode 3 is greater than the first distance, and the first distance is the minimum safety distance required between the first electrode 2 and the second electrode 3.
[0019] The working principle of this embodiment is: when the first electrode 2 and the second electrode 3 are respectively connected to the power supply, the dischargeable gas in the sealed cavity 11 is bombarded, thereby generating multiple arcs between the curved side wall 12 and the flat side wall 13, thereby emitting ultraviolet light. Since the first electrode 2 is fitted and connected to the curved side wall 12, and the second electrode 3 is fitted and connected to the flat side wall 13, the first electrode 2 and the second electrode 3 are arranged opposite to each other, so the multiple arcs will be evenly distributed along the outer periphery of the curved side wall 12 as a whole. Therefore, the arrangement of the multiple arcs on the flat side wall 13 is denser than that on the curved side wall 12, that is, the light emitted from the flat side wall 13 is more concentrated. When working, the irradiated object is arranged on the outside of the flat side wall 13. At this time, the excimer lamp has a better irradiation effect on the irradiated object.
[0020] Exemplarily, a chamfer is provided at a connection between the arc-shaped side wall 12 and the flat side wall 13 , so that an end of the arc-shaped side wall 12 smoothly transitions to an end of the flat side wall 13 .
[0021] Exemplarily, the connection between the arc-shaped side wall 12 and the flat side wall 13 is covered with an insulating protective pad 4. The provision of the protective pad 4, on the one hand, protects the connection between the arc-shaped side wall 12 and the flat side wall 13, and on the other hand, prevents creepage between the end of the first electrode 2 and the end of the second electrode 3, thereby ensuring safety.
[0022] Exemplarily, the inner side of the curved side wall 12 is covered with a reflective film 5, and the inner side of the curved side wall 12 refers to the side of the curved side wall 12 close to the inside of the lamp tube 1. The setting of the reflective film 5 does not affect the connection between the curved side wall 12 and the first electrode 2. The reflective film 5 can reflect the light scattered toward the curved side wall 12 and make it emit from the flat side wall 13, which helps to improve the utilization rate of the light, thereby improving the illumination effect on the illuminated object.
[0023] Exemplarily, the first electrode 2 is one of a metal block, a metal sheet, a metal mesh and a conductive film, all of which can achieve conductive connection with a power source. Since the metal sheet, the metal mesh and the conductive film are thin, the entire excimer lamp can maintain a small volume, which is convenient for use and carrying and transportation.
[0024] Exemplarily, the first electrode 2 is made of a reflective material. When the first electrode 2 is a metal block or a metal sheet or a conductive film, the first electrode 2 can reflect light and reflect the light scattered toward the curved side wall 12 without the need to provide a reflective film 5 separately.
[0025] Exemplarily, the second electrode 3 is one of a metal block, a metal sheet, a metal mesh and a conductive film, and can be well fitted and connected with the outer side of the flat side wall 13. Since the irradiated object is located on the outer side of the flat side wall 13 during operation, it can be understood that the ultraviolet light emitted by the excimer lamp during operation can pass through the second electrode 3 to irradiate the irradiated object. If the inner electrode is a metal mesh, the ultraviolet light can pass through the mesh. If the inner electrode is a metal block or a metal sheet, a light-transmitting hole is provided thereon. If the inner electrode is a conductive film, it is a light-transmitting conductive film.
[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
