As shown in FIGS. 1-3, the first embodiment of the present invention is provided.
An excimer lamp comprises a lamp tube 1, a first electrode 2 and a second electrode 3, wherein the number of the lamp tube 1 is at least three, discharge gas is filled in the lamp tube 1, the lamp tube 1 is distributed around a transverse axis, in the embodiment, the number of the lamp tube 1 is six, the lamp tube 1 is uniformly distributed around the transverse axis, and the distances from the axis of each lamp tube 1 to the surrounding axis are equal, so that the luminous efficacy of an irradiated object subjected to the lamp tube 1 in each direction is the same, and in order to improve the light transmittance, the lamp tube 1 uses high-purity synthetic quartz glass as a material; the first electrode 2 is arranged at one end of the lamp tube 1, the first electrode 2 is sleeved on the lamp tube 1 and is respectively connected with the outer side of the lamp tube 1, one side of the lamp tube 1, which is close to the surrounded transverse axis, is the inner side, and the other corresponding side is the outer side; the second electrode 3 is disposed at the other end of the lamp tube 1, and the second electrode 3 is sleeved on the lamp tube 1 and is connected to the outer side of the lamp tube 1.
The working principle of the embodiment is as follows: in the embodiment, the first electrode 2 and the second electrode 3 are respectively connected with the outer sides of two ends of the lamp tube 1, so that after the first electrode 2 and the second electrode 3 are electrified, the electric arcs with the first electrode 2 and the second electrode 3 as two ends and the middle part bent towards the inner side of the lamp tube 1 are respectively formed in each lamp tube 1, each lamp tube 1 mainly concentrates to emit light towards the inner side, the irradiated object is arranged at the inner side of the lamp tube 1, and the luminous efficacy of the excimer lamp is effectively improved.
Illustratively, adjacent lamps 1 are connected, so that a cavity 11 with a closed periphery is formed on the inner sides of the lamps 1 for placing an object to be irradiated, which is convenient for placing, and in addition, because no gap exists between the lamps 1, light is prevented from being dispersed, thereby improving luminous efficacy.
Since the first electrode 2 and the second electrode 3 are respectively connected to the outer side of the lamp tube 1, the inner side of the lamp tube 1 is not supported by the first electrode, and generally both ends of the lamp tube 1 need to be fixed in order to prevent the lamp tube 1 from falling, in this embodiment, for example, a support member 12 for supporting and fixing the lamp tube 1 is disposed on the inner side of the lamp tube 1, the support member 12 is respectively connected to the inner side of the lamp tube 1, and can support and fix the lamp tube 1 and facilitate the object to be irradiated to be placed on the inner side of the lamp tube 1, and the support member 12 can slide relative to the lamp tube 1 to adjust the storage space on the inner side of the lamp tube 1.
Illustratively, the outer side of the lamp tube 1 is covered with a reflective layer 13 for reflecting a small amount of light scattered to the outer side, so that the emitted light is intensively irradiated to the inner side of the lamp tube 1.
The wavelength of the emitted light can be changed by changing the dischargeable gas filled in the lamp tube 1, as shown in table 1, exemplarily, the wavelength of the light emitted by the lamp tube 1 is 100nm to 255nm, the light with the wavelength in this range has good sterilization performance, for example, the light with the wavelength of 253.7nm has strong destructive power to microorganisms, after the light irradiates the bacteria, the nucleoprotein and ribonucleic acid (d.n.a) of the bacterial cells strongly absorb the energy of this waveband, thereby opening and breaking the chains between them, causing bacterial death, and achieving the sterilization and disinfection effects, for example, the ultraviolet light with the wavelength of 172nm has the energy of 7.2eV, which is enough to open most molecular bonds, can achieve the photochemical reaction which is difficult or impossible to achieve at all in the conventional low-pressure mercury lamp, can be widely applied to surface cleaning, surface etching and modification, low-temperature photochemical vapor deposition, and the like, and if the ultraviolet light with the wavelength of 222nm cannot penetrate the stratum corneum of human skin, is harmless to human body, but has the same sterilization effect as the traditional ultraviolet lamp.
