Abstract
Description
Technical Field
[0001] This utility model relates to the field of mercury lamp technology, specifically a pen-shaped mercury lamp. Background Technology
[0002] Mercury lamps are common gas discharge lamps widely used in lighting, ultraviolet radiation, and other fields. Their typical structure includes a transparent bulb containing electrodes and filled with a rare gas (such as argon) and liquid mercury. During the manufacturing process of mercury lamps, due to technological limitations, some impurity gases inevitably remain inside the bulb. These impurity gases can affect the lamp's performance and lifespan.
[0003] To address this issue, traditional mercury lamps typically feature an inflation port at the fixed end of the bulb and an exhaust port at the other end near the discharge electrode. During operation, high-purity rare gas is injected into the bulb through the inflation port, and the airflow expels any remaining impurities through the exhaust port, thus improving the purity of the gas inside the bulb. However, this structure has a significant drawback: the presence of the exhaust port causes a discontinuous structure in the bulb, disrupting its integrity and affecting the stability of the discharge arc. This can lead to problems such as fluctuating light output and shortened lifespan.
[0004] Therefore, there is an urgent need for an improved mercury lamp structure that can maintain the stability of the discharge arc while effectively removing impurity gases, thereby improving the overall performance of the mercury lamp. Utility Model Content
[0005] To address the technical problems in the background art, this utility model discloses a pen-shaped mercury lamp.
[0006] This utility model provides a pen-shaped mercury lamp, including a bulb and an electrode disposed inside the bulb. The generating end of the electrode extends into the air cavity of the bulb, and the mounting end of the bulb is connected to an inflation pipe and an exhaust pipe.
[0007] The inflation tube is connected to the air chamber;
[0008] The exhaust pipe is connected to the air chamber.
[0009] Furthermore, the air chamber is U-shaped, with the inflation pipe and the exhaust pipe connected to one end of the air chamber, respectively.
[0010] Furthermore, a baffle extending along the axial direction of the bubble shell is provided inside the bubble shell; one end of the baffle is fixedly connected to the mounting end of the bubble shell, and the other end is spaced apart from the bubble shell; the baffle divides the air chamber into a U-shape.
[0011] Furthermore, the electrodes are located on both sides of the partition.
[0012] Furthermore, the bubble shell is composed of a light-emitting part and a mounting part connected to each other; the light-emitting part is used to emit light, and the air cavity is disposed inside the light-emitting part; the mounting part is used to mount and fix the bubble shell, and the electrode is fixedly mounted on the mounting part.
[0013] Furthermore, the mounting section is provided with an inflation port and an exhaust port; one end of the inflation port is connected to the air chamber and the other end is connected to the inflation pipe; one end of the exhaust port is connected to the air chamber and the other end is connected to the exhaust pipe.
[0014] Furthermore, the power-generating end of the electrode is arc-shaped.
[0015] The beneficial effects of this utility model are:
[0016] 1. Through the independent design of the inflation pipe and the exhaust pipe, the directional flow of high-purity rare gas and the effective discharge of impurity gas are achieved, while avoiding the damage to the bubble shell structure caused by traditional air outlets, thus maintaining the integrity and mechanical strength of the bubble shell.
[0017] 2. The continuity of the bubble shell structure eliminates the discharge arc disturbance caused by traditional air outlets, making the arc distribution more uniform, significantly reducing light output fluctuations, and improving luminous efficiency and spectral stability. It is especially suitable for application scenarios with high requirements for light source stability.
[0018] 3. The efficient removal of impurity gases reduces electrode corrosion and gas pollution, while the optimized discharge environment reduces electrode wear, thereby extending the working life of the mercury lamp. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0023] like Figure 1 As shown, and with Figure 1 For reference, this utility model discloses a pen-shaped mercury lamp, including a bulb 1 and an electrode 2 disposed inside the bulb 1.
[0024] The bulb 1 is composed of a light-emitting part 11 and a mounting part 12 connected to each other. The light-emitting part 11 is hollow, forming an air cavity 3, which is filled with rare gas and liquid mercury for emitting light. The mounting part 12 is used to mount and fix the bulb 1.
[0025] The mounting part 12 is integrally connected with a partition 6, which extends along the axial direction of the bubble shell 1 and evenly divides the air cavity 3 into two parts; there is a gap between the left end of the partition 6 and the left end of the bubble shell 1, so that the air cavity 3 forms a U shape.
[0026] An inflation pipe 4 and an exhaust pipe 5 are installed at intervals and symmetrically arranged on the right end of the mounting part 12. An inflation hole 13 is provided at the upper end of the partition 6 of the mounting part 12. The left end of the inflation hole 13 is connected to the air chamber 3, and the right end is connected to the inflation pipe 4. An exhaust hole 14 is provided at the lower end of the mounting part 12 of the partition 6. The left end of the exhaust hole 14 is connected to the air chamber 3, and the right end is connected to the exhaust pipe 5.
[0027] Two electrodes 2 are disposed on both sides of the partition 6. The right end of the electrode 2 is mounted on the mounting part 12, and the left end is the discharge end, extending into the gas chamber 3.
[0028] Rare gas is filled into the vent 14, which can stably discharge the impurity gas in the bubble shell 1.
[0029] Therefore, the above configuration has the following advantages: 1. The independent design of the inflation pipe 4 and the exhaust pipe 5 achieves the directional flow of high-purity rare gases and the effective discharge of impurity gases, while avoiding the damage to the bulb structure caused by traditional venting holes, thus maintaining the integrity and mechanical strength of the bulb. 2. The continuity of the bulb structure eliminates the discharge arc disturbance caused by traditional venting holes, making the arc distribution more uniform, significantly reducing light output fluctuations, and improving luminous efficiency and spectral stability, making it particularly suitable for applications with high requirements for light source stability. 3. The efficient removal of impurity gases reduces electrode corrosion and gas pollution, while the optimized discharge environment reduces electrode wear, thereby extending the working life of the mercury lamp.
[0030] The left end of electrode 2 is set in an arc shape, which has the following advantages: the arc shape makes the electric field distribution more uniform, thereby reducing arc flicker and local overheating, significantly improving discharge stability, and ensuring the consistency and reliability of light output intensity; moreover, the improvement of arc stability reduces abnormal wear of electrode 2 material, while the uniform electric field distribution slows down electrode 2 degradation, thereby extending the overall service life of mercury lamp.
[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
