For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0037] The implementation of the present invention is described in detail below with reference to specific embodiments.

[0038] Reference Figure 1-12 As shown, a preferred embodiment of the present invention is provided.

[0039] An excimer lamp, characterized by comprising:

[0040] A first lamp cap 1, the first lamp cap 1 is made of a heat-conducting but non-conducting material;

[0041] A second lamp cap 2, which is arranged opposite to the first lamp cap 1 and is made of a heat-conducting but non-conducting material;

[0042] A first electrode head 3, which is installed in the first lamp head 1 and is used to connect to an external power source;

[0043] A second electrode head 4, which is installed in the second lamp head 2 and is used to connect to an external power source;

[0044] A conductive heat dissipation rod 5, both ends of which are respectively installed in the first lamp cap 1 and the second lamp cap 2, and the conductive heat dissipation rod 5 is electrically connected to the first electrode cap 3;

[0045] A light-transmitting annular sleeve 6 is arranged around the conductive heat dissipation rod 5. The extending direction of the light-transmitting annular sleeve 6 is consistent with the extending direction of the conductive heat dissipation rod 5. The annular sleeve has an accommodating space filled with excimer gas;

[0046] The conductive ring network 7 is arranged around the light-transmitting annular sleeve 6 . The extending direction of the conductive ring network 7 is consistent with the extending direction of the light-transmitting annular sleeve 6 . One end of the conductive ring network 7 is electrically connected to the second electrode head 4 .

[0047] The luminous principle of the above-mentioned excimer lamp is: the first electrode head 3 is connected to the power supply, the conductive heat dissipation rod 5 is electrically connected to the first electrode head 3, the second electrode head 4 is connected to the power supply, the second electrode head 4 is electrically connected to the conductive ring network 7, the transparent annular sleeve 6 is arranged around the conductive heat dissipation rod 5, and the conductive ring network 7 is arranged around the transparent annular sleeve 6, which is equivalent to forming two oppositely arranged electrodes on the inside and outside of the transparent annular sleeve 6, and a discharge space is formed between the two electrodes. When a sufficiently high discharge voltage is applied to the two electrodes, the excimer gas in the transparent annular sleeve 6 in the discharge space will be broken down, forming a dielectric barrier discharge, and will generate ultraviolet light.

[0048] The excimer lamp provided above, through the arrangement of the conductive heat sink 5, a large amount of heat generated by the light emission in the light-transmitting annular sleeve 6 is dissipated and conducted through the conductive heat sink 5, and then dissipated and conducted through the first lamp head 1; at the same time, the conductive ring network 7 can dissipate the large amount of heat generated by the light emission in the light-transmitting annular sleeve 6 and conduct it through the second lamp head 2; this structural arrangement greatly improves the heat dissipation effect of the entire excimer lamp, conducts the heat of the light-transmitting annular sleeve 6, and reduces the temperature inside the light-transmitting annular sleeve 6, thereby stabilizing the excitation efficiency of the excimer lamp, thereby generating continuous and stable ultraviolet light.

[0049] It should be noted that the excimer gas refers to a mixed gas formed by mixing an inert gas and a halogen gas.

[0050] Preferably, the first lamp holder 1 and the second lamp holder 2 are made of ceramic material. First, ceramic material has good thermal conductivity and ceramic is not conductive. Second, the light-transmitting annular conduit can be made of glass or sapphire. The conductive ring net 7 and the conductive heat dissipation rod 5 are made of metal material. They have good conductive properties and good heat dissipation performance.

[0051] Specifically, the transparent annular sleeve 6 includes an inner tube 61 and an outer tube 62 connected to the inner tube 61 . There is a gap between the inner tube 61 and the outer tube 62 , and the gap forms an accommodating space; the excimer gas is arranged in the accommodating space.

[0052] The light-transmitting annular sleeve 6 has an opening connected to the accommodating space, and the light-transmitting annular sleeve 6 is also provided with a tube cover for opening or sealing the opening. When it is necessary to fill the light-transmitting annular sleeve 6 with excimer gas, it is only necessary to open the tube cover and flush the excimer gas into the light-transmitting annular sleeve 6 from the opening. After the excimer gas is filled, it is only necessary to close the tube cover.

[0053] As an embodiment of the present invention, the excimer lamp also includes a conductive heat dissipation tube 8, the extension direction of the conductive heat dissipation tube 8 is consistent with the extension direction of the conductive heat dissipation rod 5, the inner wall of the conductive heat dissipation tube 8 is arranged around the conductive heat dissipation rod 5, and there is a gap between the conductive heat dissipation tube 8 and the conductive heat dissipation rod 5, the gap is filled with an elastic conductive material 9, and the outer wall of the conductive heat dissipation tube 8 fits the inner tube 61 of the light-transmitting annular sleeve 6; in this way, first, by filling the gap with an elastic conductive material 9, such as a metal mesh, an electrical connection between the conductive heat dissipation rod 5 and the conductive heat dissipation tube 8 is achieved, which is equivalent to the conductive heat dissipation tube 8 and the conductive ring network 7. The electrodes are arranged relative to each other to excite the excimer gas in the light-transmitting annular sleeve 6. At the same time, since the light-transmitting annular sleeve 6 generates a large amount of heat when it is emitting light, the light-transmitting annular sleeve 6 is prone to thermal expansion. Since the inner tube 61 of the light-transmitting annular sleeve 6 is in contact with the outer wall of the conductive heat dissipation tube 8, a gap exists between the conductive heat dissipation tube 8 and the conductive heat dissipation rod 5. The gap is filled with elastic conductive material. In this way, even if the light-transmitting annular sleeve 6 undergoes thermal expansion, it has a certain amount of space for thermal expansion and deformation, and will not be broken due to compression, thereby improving the service life of the light-transmitting annular sleeve 6. Specifically, the conductive heat dissipation tube 8 is made of a metal with good electrical and thermal conductivity.

[0054] As an embodiment of the present invention, there are multiple light-transmitting annular sleeves 6, and multiple light-transmitting annular sleeves 6 are arranged in sequence and at intervals along the extension direction of the light-transmitting annular sleeves 6.

The annular heat dissipation fins 10 can be made of a ceramic material with good thermal conductivity. This arrangement is very conducive to the dissipation of heat generated by the light-transmitting annular sleeve 6.

The isolation ceramic 22 isolates the conductive cooling rod 5 and the fixing nut 21, that is, the isolation of the conductive cooling rod 5 and the second electrode head 4 is achieved.

[0057] Specifically, one end of the conductive heat dissipation rod 5 close to the third connection section 222 has a groove, and the third connection section 222 is embedded in the groove to achieve mating contact with the conductive heat dissipation rod 5 .
