Description

near-infrared therapy device

[0001] The present invention relates to a near-infrared treatment device, and more specifically, to a near-infrared treatment device that can improve the treatment effect of a near-infrared treatment device and improve the durability of the near-infrared treatment device by concentrating near-infrared rays output from a plurality of near-infrared LED chips using a lens module and irradiating the near-infrared rays to a treatment area.

[0002] In general, an infrared therapy device is a treatment device that uses infrared rays to deliver heat to the skin or muscle tissue. It emits the thermal energy of infrared radiation and delivers it to the deep layers of the skin to relieve pain, relax muscles, improve blood circulation, and is used for various medical and health-related purposes.

[0003] Infrared is a general term for the band of 700 nm to 1 mm, which is a band with a wavelength longer than the visible light wavelength band (400 nm to 700 nm). Infrared is a representative form of radiant energy that directly transfers energy from a high-temperature object to a low-temperature object without a medium, and is widely used for medical purposes to transfer energy to the human skin or deep parts.

[0004] Most infrared treatment devices use infrared lamps, such as halogen lamps, to irradiate the treatment area with infrared rays in order to maximize the therapeutic effect.

[0005] For example, various structures of infrared therapy devices using infrared lamps are disclosed in Korean Patent Publication No. 10-2019-0002225 (Lamp combination structure of infrared therapy device) (published on January 8, 2019) and Korean Patent Registration No. 10-2161564 (Infrared lamp device for thermal therapy device) (announced on October 5, 2020).

[0006] However, conventional infrared therapy devices have the problem that the infrared rays themselves are not evenly distributed from the infrared lamps, and because they irradiate a wide area of ​​the treatment area using the infrared lamps, the infrared rays are dispersed, reducing the treatment effect. Consequently, conventional infrared therapy devices require large lenses to irradiate a narrow area of ​​the treatment area, increasing the overall size and complicating the structure.

[0007] Furthermore, conventional infrared therapy devices had the inconvenience of having to be held close to the treatment area to address the reduced therapeutic effect caused by infrared dispersion. Furthermore, conventional infrared therapy devices had the drawback of significantly reduced durability due to heat generation from the infrared lamp.

[0008] Meanwhile, near-infrared therapy devices utilizing near-infrared rays are also being developed. For example, various structures of near-infrared therapy devices utilizing near-infrared rays are disclosed in Korean Utility Model Publication No. 20-0290062 (Personal Thermal Therapy Device Using Near-Infrared Rays) (published on September 26, 2002) and Korean Patent Publication No. 10-2022-0130935 (Near-Infrared LED Heater Module for Phototherapy) (published on September 27, 2022).

[0009] However, conventional near-infrared treatment devices, like infrared lamps, irradiate near-infrared rays over a wide area of ​​the treatment area, which has the problem that the near-infrared rays are dispersed, reducing the treatment effect.

[0010] Therefore, a near-infrared treatment device that can improve the treatment effect of the near-infrared treatment device and improve the durability of the near-infrared treatment device is required.

[0011] The present invention was invented to improve the above-mentioned problems, and the problem to be solved by the present invention is to provide a near-infrared treatment device that can improve the treatment effect of the near-infrared treatment device by concentrating near-infrared rays output from a plurality of near-infrared LED chips using a lens module and irradiating the near-infrared rays to the treatment area.

[0012] The technical problems of the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0013] In order to achieve the above object, a near-infrared treatment device according to one embodiment of the present invention is characterized by including: a substrate; a plurality of near-infrared LED chips mounted on one surface of the substrate and emitting near-infrared rays; and a lens module disposed adjacent to the plurality of near-infrared LED chips and including at least one lens for concentrating near-infrared rays output from the plurality of near-infrared LED chips and irradiating the near-infrared rays to a treatment area.

[0014] At this time, the plurality of near-infrared LED chips are characterized in that they generate near-infrared rays having a wavelength band of any one of 830 nm, 850 nm, and 940 nm.

[0015] In addition, the plurality of near-infrared LED chips are characterized in that they are mounted on the substrate in a COB (Chip-On-Board) manner.

[0016] In addition, the lens module is characterized by including a first lens disposed above the plurality of near-infrared LED chips and collecting near-infrared light output from the plurality of near-infrared LED chips; and a second lens disposed above the first lens and focusing the near-infrared light passing through the first lens onto the treatment area in the form of a spot.

[0017] In addition, the first lens is arranged to surround the plurality of near-infrared LED chips, and uses a hemispherical convex lens that protrudes in a hemispherical shape to collect near-infrared rays output from the plurality of near-infrared LED chips, and the second lens uses a flat block lens that collects near-infrared rays that have passed through the first lens.

[0018] Meanwhile, the near-infrared treatment device is characterized in that it further includes a cooling module that is positioned adjacent to the substrate and cools heat generated from the plurality of near-infrared LED chips.

[0019] Specific details of other embodiments are included in the detailed description and drawings.

[0020] According to a near-infrared treatment device according to one embodiment of the present invention, the treatment effect of the near-infrared treatment device can be improved by focusing near-infrared rays output from a plurality of near-infrared LED chips using a lens module and irradiating the near-infrared rays to a treatment area.

[0021] In addition, according to a near-infrared treatment device according to one embodiment of the present invention, by having a cooling module that cools heat generated from a plurality of near-infrared LED chips, the problem of the near-infrared treatment device being damaged due to heat can be prevented and the durability of the near-infrared treatment device can be improved.

[0028] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings to enable a person having ordinary skill in the art to easily carry out the present invention.

This is to avoid obscuring the gist of the present invention by omitting unnecessary explanations and to convey the gist more clearly.

[0030] For the same reason, some components in the attached drawings are exaggerated, omitted, or schematically depicted.

[0031] Additionally, it will be appreciated that expressions and terms used herein with respect to device or element orientation (e.g., “front,” “back,” “up,” “down,” “top,” “bottom,” “left,” “right,” “lateral”) are used merely to simplify the description of the invention and do not indicate or imply that the associated device or element must have a particular orientation.

[0032] Hereinafter, the present invention will be described with reference to drawings for explaining a near-infrared treatment device according to one embodiment of the present invention.

[0033] FIG. 1 is a perspective view schematically showing the structure of a near-infrared treatment device according to one embodiment of the present invention, FIG. 2 is a longitudinal cross-sectional view schematically showing the structure of a near-infrared treatment device according to one embodiment of the present invention, FIG. 3 is a drawing schematically showing the structure of a plurality of LED chips constituting a near-infrared treatment device according to one embodiment of the present invention, and FIG. 4 is a drawing schematically showing the structure of a lens module constituting a near-infrared treatment device according to one embodiment of the present invention.

[0034] As illustrated in FIGS. 1 and 2, a near-infrared treatment device (100) according to one embodiment of the present invention may be configured to include a substrate (100), a plurality of near-infrared LED chips (120), and a lens module (130).

[0035] The substrate (100) is installed inside the housing (101) of the near-infrared treatment device (100), and a plurality of near-infrared LED chips (120), etc. can be mounted on one side (the upper side in the example of FIG. 2). The substrate (100) can use a printed circuit board, a flexible printed circuit board (FPCB), etc.

[0036] A plurality of near-infrared LED chips (Infrared Light emitting diode chips) (120) are mounted on one surface of the substrate (100) (in the example of FIG. 2, the upper surface of the substrate (100)) and can output near-infrared light (L) having a wavelength band of approximately 780 nm to 3,000 nm to treat a treatment area.

[0037] These near infrared (L) rays are mainly used to treat wounds, burns, scars, and inflammation. When the light emitted from sunlight or a heating source is dispersed into a spectrum, it has the shortest wavelength in the infrared (L) outside the red spectrum. In addition to the thermal effect, it has photoelectric and fluorescent effects, so it is used for disinfection, sterilization, and joint and muscle treatment. It also produces nitric oxide (NO), which provides rapid pain relief.

[0038] Preferably, the near-infrared LED chip (120) constituting the near-infrared treatment device (100) according to one embodiment of the present invention can generate near-infrared (L) having a wavelength band of 830 nm, 850 nm, or 940 nm.

[0039] Preferably, as illustrated in FIG. 3, a plurality of near-infrared LED chips (120) can be mounted on a substrate (100) in a COB (Chip-On-Board) manner. The COB (Chip-On-Board) manner is one of the integrated circuit technologies used in the production of electronic products and circuits, and since the near-infrared LED chips (120) are directly attached to a printed circuit board (PCB), a flexible printed circuit board (FPCB), etc., no other packaging or case is required, so that the overall size can be miniaturized and the cost can be reduced, and the electrical performance can be improved and the resistance to shock and vibration can be high, so that reliability can be achieved.

[0040] The lens module (130) is positioned adjacent to a plurality of near-infrared LED chips (120) and may include at least one lens that focuses near-infrared light (L) output from the plurality of near-infrared LED chips (120) and irradiates the near-infrared light to the treatment area.

[0041] Preferably, as shown in FIG. 4, the lens module (130) may be configured to include a first lens (131) and a second lens (132).

[0042] The first lens (131) is positioned above a plurality of near-infrared LED chips (120) and can collect near-infrared rays (L1) output from the plurality of near-infrared LED chips (120), and the second lens (132) is positioned above the first lens (131) and can focus near-infrared rays (L2) passing through the first lens (131) onto the treatment area in the form of a spot (S in FIG. 1).

[0043] That is, since the lens module (130) can irradiate the near-infrared (L) output from a plurality of near-infrared LED chips (120) to the treatment area in a spot form, the reduction in treatment effect due to dispersion of the near-infrared (L) can be resolved, and since the near-infrared (L) is not dispersed, a sufficient distance from the treatment area can be secured. At this time, the near-infrared (L) irradiated by the lens module (130) can be irradiated in a spot form with a radius of approximately 200 mm when the distance from the treatment area is 1 m.

[0044] Preferably, as illustrated in FIG. 4, the first lens (131) is arranged to surround a plurality of near-infrared LED chips (120), and a hemispherical convex lens protruding in a hemispherical shape may be used to collect near-infrared rays (L1) output from the plurality of near-infrared LED chips (120). In addition, the second lens (132) may be a flat block lens that collects near-infrared rays (L2) that have passed through the first lens (131).

[0045] In this way, the near-infrared treatment device (100) according to one embodiment of the present invention can improve the treatment effect of the near-infrared treatment device (100) by focusing the near-infrared rays (L) output from a plurality of near-infrared LED chips (120) using a lens module (130) and irradiating them to the treatment area.

[0046] Meanwhile, a near-infrared treatment device (100) according to one embodiment of the present invention may further include a cooling module (140) that cools heat generated from a plurality of near-infrared LED chips (120).

[0047] FIG. 5 is a drawing schematically showing the structure of a cooling module constituting a near-infrared treatment device according to one embodiment of the present invention.

[0048] As shown in FIG. 5, a cooling module (140) is positioned adjacent to the substrate (100) and can cool heat generated from a plurality of near-infrared LED chips (120).

[0049] Preferably, the cooling module (140) may have an air-cooling structure that discharges heat generated from a plurality of near-infrared LED chips (120) to the outside. That is, as illustrated in FIG. 5, the cooling module (140) may be configured with a heat sink (141) that is installed on one surface of the substrate (100) (in the example of FIG. 5, the lower surface of the substrate (100)) and disperses heat generated from a plurality of near-infrared LED chips (120), and a cooling fan (142) that is installed at a position adjacent to the heat sink (141) and discharges heat transferred from the heat sink (141) to the outside.

[0050] Meanwhile, FIG. 5 illustrates an example in which two cooling fans (142) are installed at the bottom on both sides of one heat sink (141) placed on the lower surface of the substrate (110), but is not limited thereto, and the number and arrangement of the heat sinks (141) and cooling fans (142) can be changed at any time by those skilled in the art.

[0051] Although not shown, the cooling module (140) may include a heat transfer member (not shown) having high thermal conductivity installed between the substrate (100) and the heat sink (141) in order to improve the heat transfer efficiency generated from the plurality of near-infrared LED chips (120) and the substrate (100) in addition to the heat sink (141) and the cooling fan (142).

[0052] In this way, the near-infrared treatment device (100) according to one embodiment of the present invention has a cooling module (140) that cools heat generated from a plurality of near-infrared LED chips (120), thereby preventing the problem of the near-infrared treatment device (100) being damaged due to heat and improving the durability of the near-infrared treatment device (100).

[0053] Meanwhile, this specification and drawings disclose preferred embodiments of the present invention. Although specific terms are used, they are used in a general sense only to easily explain the technical content of the present invention and to aid in understanding the invention, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical concept of the present invention are possible in addition to the embodiments disclosed herein.

[0054] The present invention relates to a near-infrared treatment device, and more specifically, is applicable to a technical field related to a near-infrared treatment device that improves the treatment effect by irradiating a treatment area with near-infrared rays.
