Embodiment Construction

[0024] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0025] Such as Figure 1-4 A rectangular excimer lamp that emits uniform parallel light on both sides as shown includes a cathode 3, an anode 5 and a square tube 1, the square tube 1 is filled with working gas, the square tube 1 is a cylinder or a cuboid, and the square tube 1 is Made of quartz glass. The working gas is a mixed gas of Xe and Cl. The working gas can be any gas that is excited, for example, a mixed gas of Xe and Cl can be used to obtain light with a wavelength of 308nm. The principle is: chlorine is a halogen element, and xenon is an inert gas. Under normal circumstances, chlorine and xenon will not react, and there is no compound of chlorine and xenon in nature, but under the action of hig...

Abstract

The invention relates to the technical field of excimer lamps, in particular to a rectangular excimer lamp capable of emitting uniform parallel light from two sides, which comprises a cathode, an anode and a square tube, wherein the square tube is filled with working gas; a mounting groove extending into the square tube is formed in the end surface of one end of the square tube; the anode is a sheet-shaped electrode and is mounted in the mounting groove; the cathode is wound on the outer wall of the square tube; and when power supply voltage is applied to the cathode and the anode, working gasin the square tube is excited to generate light and the light is outputted on the surfaces of the square tube on the upper side and the lower side of the anode. Thus, 308nm light can be output, parallel light can be outputted to two directions at the same time, and the utilization efficiency of excimer light is improved.

Description

technical field [0001] The invention relates to the field of excimer lamps, in particular to a rectangular excimer lamp emitting uniform parallel light from both sides. Background technique [0002] At present, there are the following problems in the phototherapy instruments for treating vitiligo and psoriasis on the market: 1. 308nm excimer lamps are counterfeit --- ordinary fluorescent tubes are used to pretend to be 308nm excimer lamps. 2. Genuine 308nm excimer lamps also have problems such as low optical power, unstable optical power, and excessive temperature of the lamp during operation. 3. Due to the limitation of the internal space of the equipment or the different environments, the circular lamps on the market cannot meet the requirements. However, the market demand for 308nm excimer lamps continues to increase, so this small, rectangular 308nm excimer lamp came into being. 4. Uneven light emission. Contents of the invention [0003] The object of the present i...
