In one embodiment, the two or more filaments in the filament assembly are 1 or more first filaments and 1 or more second filaments, and the term "above" is included herein. This example is described in detail below:

fig. 1 is a schematic structural diagram of an infrared light source of the present invention.

Referring to fig. 1 and 2, the infrared light source 1 includes: a base plate 100 (see fig. 2) including a first surface a; a plurality of discrete support members 106 (see fig. 2) provided on the first surface a of the base plate 100; a first filament 101 and a second filament 102 (see fig. 1) supported by the support 106 and arranged separately, the first filament 101 being configured to emit light of a first wavelength; the second filament 102 is used for emitting light of a second wavelength; a fixing member 109 (see fig. 1) provided on the top of the support 106 for fixing the first and second filaments 101 and 102; a top cover 108 (see fig. 2) cooperating with the base plate 100 to form a closed space for accommodating the support 106, the first filament 101 and the second filament 102; the first filament 101 is connected with an external power supply through a first group of electrodes 111 at two ends of the first filament 101; the second filament 102 is connected to an external power source through a second set of electrodes 112 across the second filament 102.

The material of the base plate 100 comprises quartz, and the base plate 100 is used for carrying the support 106, the first filament 101, the second filament 102 and the top cover 108.

The material of the support 106 includes ceramic, so that electricity from the first and second filaments 101 and 102 is not transmitted along the support 106, and thus, the support 106 serves only to support the first and second filaments 101 and 102. Specifically, one support 106 may support a plurality of first filaments 101 and a plurality of second filaments 102, and one support 106 may also support 1 first filament 101 or 1 second filament 102.

In this embodiment, the number of the first filaments 101 is 4, and the number of the second filaments 102 is 4, which are taken as an example for schematic description, and actually, the number of the first filaments 101 and the second filaments 102 in the infrared light source is not limited, and can be designed according to actual requirements.

In one embodiment, the gap between adjacent first and second filaments 101, 102 ranges from more than 6 mm to less than 15 mm, and the gap between the first and second filaments 101, 102 is selected in the sense that: if the gap between the first filament 101 and the second filament 102 is larger than 15 mm, the cold area between the first filament 101 and the second filament 102 which is not heated is larger, which is not beneficial to improving the heating uniformity of the infrared light source; if the gap between the first filament 101 and the second filament 102 is less than 6 mm, the manufacturing difficulty is large.

In this embodiment, the first filament 101 and the second filament 102 are made of different materials, and the filaments made of different materials emit different infrared lights after being heated, so that when the first filament 101 and the second filament 102 are made of different materials, the infrared light source can generate lights with two wavelengths, and the infrared light source is used for treating diseases requiring the two wavelengths.

In one embodiment, the material of the first filament 101 comprises: tungsten, the first filament 101 heats and emits infrared light with a first wavelength, and the range of the first wavelength generated under certain heating regulation is as follows: 2-4 microns; the material of the second filament 102 includes carbon fiber, and under a certain heating condition, the second filament 102 is heated to emit infrared light with a second wavelength, where the second wavelength is in a range of: 9 to 11 microns. Tungsten filament and carbon fiber filament can produce the bispectral radiation the same with traditional moxa-moxibustion, consequently, infrared light source can reach the effect of traditional moxa-moxibustion.

In one embodiment, when the first filament 101 and the second filament 102 are made of carbon fiber, the first filament 101 and the second filament 102 have a mesh-shaped surface structure. The temperature of the first filament 101 and the second filament 102 is independently controlled to generate light with two different wavelengths, so as to meet the disease treatment requirement of the two different wavelengths.

In order to prevent the first and second filaments 101 and 102 from being oxidized, the first and second filaments 101 and 102 need to be sealed, specifically, the first and second filaments 101 and 102 are surrounded by the top cap 108 and the bottom plate 100, and then it is not necessary to set a sealing member at the end of each of the first and second filaments 101 and 102 for separate sealing, which not only can improve the effective heating area of the infrared light source, but also can prevent the cold spot caused by the sealing member, thereby being beneficial to improving the uniformity of heating the infrared light source and reducing the difficulty and complexity of manufacturing.

Meanwhile, as the top cover 108 and the bottom plate 100 are matched to form a closed space, the first filament 101 and the second filament 102 are suspended and supported and are not in direct contact with the top cover 108 and the bottom plate 100, so that only a small part of heat for heating the first filament 101 and the second filament 102 reaches the top cover 108 and the bottom plate 100 through heat radiation and is released to the external environment, and most of heat is used for heating the first filament 101 and the second filament 102, thereby being beneficial to improving the heating efficiency of the first filament 101 and the second filament 102 and reducing the heat loss.

In one embodiment, the enclosed space is a vacuum environment, and the deformation of the infrared light source due to the pressure difference between the inside and the outside of the enclosed space should be considered, for example: the thickness of the top cover 108 and the bottom plate 100 may be increased to resist large pressure differences between the interior and exterior of the enclosed space. In another embodiment, inert gas is introduced into the enclosed space, and at this time, the pressure difference between the inside and the outside of the enclosed space borne by the top cover 108 and the bottom plate 100 is small, so that the top cover 108 and the bottom plate 100 can be made thin.

The material of the top cover 108 is an infrared light transmitting material, such as: the top cover is made of the following materials: quartz glass, chalcogenide glass, or microcrystalline glass. The material of the top cover 108 absorbs less heat from the first filament 101 and the second filament 102, and has stronger transmission capability to the infrared light generated by the first filament 101 and the second filament 102, which is beneficial for more infrared light to reach the to-be-irradiated part of the human body.

In one embodiment, as shown in fig. 2, the top cover comprises a top plate and an extension piece extending downwards from the periphery of the top plate, and the bottom of the extension piece is fixedly connected with the bottom plate to form the closed space. The first and second sets of electrodes 111 and 112 penetrate the substrate 100 to be connected to an external power source.

In another embodiment, the top cover is a plate-shaped structure, as shown in fig. 3, and fig. 3 is another cross-sectional structure schematic view along line L-L2 in fig. 1. The bottom of the top cover 108 is hermetically connected with the bottom plate 100 through a gasket 110, the gasket 110 is located at the periphery of the closed space, and the first group of electrodes 111 and the second group of electrodes 112 penetrate through the gasket 110 to be connected with an external power supply.

In order to allow more infrared light to pass through the top cover 108, an antireflection film is provided on the inner surface of the top cover 108, and the material of the antireflection film includes calcium fluoride.

The infrared light generated by heating the first and second filaments 101 and 102 may be diffused in various directions, wherein the infrared light irradiated to the to-be-irradiated portion of the human body through the top cover 108 is a portion to be effectively utilized, and the infrared light reaching the bottom plate 100 may be difficult to be utilized or even wasted, and in order to reuse the infrared light reaching the bottom plate 100, a reflective film may be disposed on the first surface a of the bottom plate 100, and the reflective film may be made of a material including: the aluminum film formed by magnetron sputtering is beneficial to reflecting the infrared light reaching the first surface A of the bottom plate 100 back to the top cover 108, so that more infrared light can reach the part to be irradiated of the human body, and the treatment effect is improved.

The infrared light source further includes: a first terminal 104 and a second terminal 105 located outside the top cover 108, the first terminal 104 being electrically connected to a first group of electrodes 111; the second terminal 105 is electrically connected to the second set of electrodes 112, a first external power source is electrically connected to the first terminal 104, and the second external power source is electrically connected to the second terminal 105.

In another embodiment, as shown in fig. 4, a first joint 104 is led out after the multiple groups of first group electrodes 111 are merged in the top cover 108, and a second joint 105 is led out after the multiple groups of second group electrodes 112 are merged in the top cover 108, which is beneficial to reducing the number of joints and reducing the difficulty of joint arrangement.

The heating conditions of the first filament 101 and the second filament 102 are independently adjustable, and the voltage applied to the first filament 101 and the second filament 102 can be adjusted according to actual needs, wherein the larger the voltage is, the higher the heating temperature in the first filament 101 and the second filament 102 in a unit time is, the more infrared light is generated, therefore, when more infrared light with a first wavelength and less infrared light with a second wavelength are needed, the voltage applied to the first filament 101 can be increased, the voltage applied to the second filament 102 can be decreased, and conversely, when more infrared light with the second wavelength and less infrared light with the first wavelength are needed, the voltage applied to the second filament 102 can be increased, and the voltage applied to the first filament 101 can be decreased. Because the first wavelength and the second wavelength are required in different amounts for treating different diseases, the ratio of the first wavelength and the second wavelength can be adjusted according to actual needs to meet the treatment requirements of different diseases.

In addition, in the present embodiment, two ends of each of the first filament 101 and the second filament 102 are fixed by a fixing member 109, so as to prevent the adjacent first filament 101 and the second filament 102 from being electrically connected.

In other embodiments, the top of the support is provided with a first recess for receiving and fixing the first and second filaments, and the fixing member may not be provided.

The fixing member 109 is made of a ceramic material.

In this embodiment, the first filament 101 and the second filament 102 are uniformly distributed in a coplanar manner, so that the thickness d of the infrared light source is relatively thin, the thickness d of the infrared light source is greater than 10 mm, the bottom plate 100 includes a second surface opposite to the first surface a, and the thickness of the infrared light source is: the distance from the second surface to the external top surface of the top cover 108, and the thickness d of the infrared light source are thinner, so that the infrared light source has smaller volume, is portable and is convenient to carry.
