Abstract
Description
LED phototherapy device with adjustable light irradiation position
[0001] The present invention relates to an LED phototherapy device capable of adjusting a light irradiation position, and more specifically, to an LED phototherapy device capable of adjusting a light irradiation position, which can adjust the position of a light source unit in the forward-reverse and up-down directions as well as the angle, thereby exhibiting an accurate light irradiation effect, improving convenience and compatibility in use, and enhancing marketability.
[0002] In general, LED (Light Emitting Diode) has been mainly used in the lighting field such as lighting fixtures, but recently it has been widely used for purposes such as treating various diseases and skin care.
[0003] LED light sources utilize the principle of promoting biochemical reactions within the skin by irradiating light onto the treatment area of the human body, thereby penetrating the skin tissue and selectively regenerating damaged areas to treat them or perform other functions such as whitening.
[0004] In particular, infrared rays have a stronger thermal effect than visible light or ultraviolet rays, so a thermal therapy device that uses this to intensively radiate infrared rays (far infrared rays), which are heat and growth rays, to the body, and the thermal effect and steaming treatment effect of infrared rays can promote metabolism, improve blood circulation, and provide muscle relaxation effects that relieve tense muscles, so the scope of treatment is gradually expanding.
[0005] Although various phototherapy devices using the aforementioned LED have been proposed, such as the ‘wavelength-type LED irradiation device’ of Korean Patent Registration No. 10-1769392, they have the following limitations.
[0006] First, the conventional wavelength-type LED irradiation device can only adjust the angle of the head, and if the user wants to adjust the irradiation angle of light directed toward the human body, there is an inconvenience in that the user must manually lift and move the LED irradiation device.
[0007] In particular, conventional wavelength-type LED irradiation devices have difficulty moving back and forth, left and right, and up and down, so when a user is sitting on a massage chair or lying on a bed or health care device, the light cannot be brought close to a specific location on the human body, and thus the therapeutic light cannot penetrate deep into the skin tissue, so there is a disadvantage in that the phototherapy effect is low.

[0033] FIG. 1 is a perspective view showing an LED phototherapy device capable of adjusting a light irradiation position according to an embodiment of the present invention, FIG. 2 is a schematic front view for explaining the operating state of an LED phototherapy device capable of adjusting a light irradiation position according to an embodiment of the present invention, FIG. 3 is a perspective view showing a shape of an LED phototherapy device capable of adjusting a light irradiation position according to an embodiment of the present invention when viewed from another direction, and FIG. 4 is an exploded perspective view showing an LED phototherapy device capable of adjusting a light irradiation position according to an embodiment of the present invention, in which the rod support part (3) is shown artificially cut out, and the fixed gear (51) is shown separately although it is configured to be integrally connected to the rod support part (3) by a joining method such as welding.
[0034] Referring to FIG. 1, an LED phototherapy device capable of adjusting a light irradiation position according to one embodiment of the present invention comprises a light source unit (1), a movable rod unit (2), a rod support unit (3), a rod drive unit (4), a rotation drive unit (5), and a fixed support unit (6), and is characterized by having a simple and concise structure while allowing the user to freely adjust the position of the light source unit (1) that irradiates light in a desired direction.
[0035] The light source unit (1) is a component that irradiates therapeutic light toward the human body, and is composed of a module base (11) and an LED module (12) installed on one side of the module base (11).
[0036] The module base (11) has no special restrictions on the detailed structure, but may be composed of a synthetic resin molded body so as to stably support the LED module (12).
[0037] The module base (11) may be formed as a flexible structure that can be bent into an arc shape when an external force is applied while it is unfolded in a straight line. In this case, it is preferable that a plastic body be formed in the module base (11) so that the deformed state of the module base is maintained. Here, the plastic body may be installed with a metal wire such as a wire or a metal plate.
[0038] The LED module (12) is formed in a conventional structure in which a number of LEDs are arranged in rows and columns on a printed circuit board, so a detailed description or illustration in the drawings is omitted. In addition, although the LEDs constituting the LED module in this embodiment are installed with infrared wavelength band LEDs, this is not limited to this, and ultraviolet wavelength band LEDs may be arranged singly or in combination.
[0039] And, a module fastening member (13) that is connected to the moving load section (2) is formed on the module base (11).
[0040] The module fastening member (13) can be configured in various ways without any particular restrictions on shape or structure as long as it can easily connect the module base (11) to the movable rod part (2), but in this embodiment, it is provided with a connecting rod (131) whose end is connected to the module base (11), and a connecting cap (132) connected to the other end of the connecting rod and connected to the movable rod part (2) by a screw or the like.
[0041] The movable rod part (2) is a component that is movably connected to the rod support part (3). There is no particular limitation on the shape if it has a rod-shaped structure, but in this embodiment, it is formed in a rod shape and a light source part (2) is installed at one end.
[0042] And the moving rod part (2) is formed as a square bar, and a rack (41) described later is formed on its upper surface.
[0043] The load support member (3) is a component to which the movable load member (2) is movably connected, and is rotatably connected to the fixed support member (6).
[0044] The load support part (3) is provided with a load support body (31) having a load moving hole (311) formed therein into which the moving load part (2) is inserted, a pinion insertion hole (32) formed on the upper surface of the load support body (31) into which a part of a pinion (42) described later is inserted, and a load driving motor installation part (33) formed on the load support body so that a load driving motor (43) is installed.
[0045] The load support body (31) is formed as a square hollow body with a load moving hole (311) formed in the front and back of the center in a shape corresponding to the cross-sectional structure of the moving load section (2).
[0046] The load driving motor installation part (33) is formed in a plate shape and protrudes on both sides from the upper part of the load support body (31), and a motor installation hole (332) for installing the load driving motor (43) is formed.
[0047] Meanwhile, the load driving unit (4) is a component installed on the load support unit (3) to perform the translational motion of the movable load unit (2), and includes a rack (41) formed on the movable load unit (2), a pinion (42) installed on the load support unit (3) to engage with the rack (41), and a load driving motor (43) having a drive shaft installed on the load support unit (3) and connected to the pinion (42). Here, the load driving motor (43) may be configured as a geared motor equipped with a reducer.
[0048] The rotary drive unit (5) is a component that rotates the load support unit (3) to perform angular movement of the movable load unit (2), and includes a fixed gear (51) formed on the load support unit (3), a rotary gear (52) meshed with the fixed gear (51), and a support unit rotation motor (53) having a drive shaft installed on the fixed support unit (6) and connected to the rotary gear (52).
[0049] The above fixed gear (51) is composed of a semicircular gear body (511) that protrudes in a semicircular shape from the bottom surface of the load support body (31) and has teeth formed on the outer periphery, and a semicircular gear having an axial hole (512) drilled in the center of the semicircular gear body (511).
[0050] The rotary gear (52) is connected to the drive shaft of the support rotary motor (53) while located inside the bearing member (61) and performs the function of transmitting the rotational power of the support rotary motor (53) to the fixed gear (51).
[0051] It is preferable that the support rotation motor (53) be configured as a step motor to facilitate adjustment of the rotation angle of the fixed gear (51).
[0052] Meanwhile, the fixed support member (6) is a component that is connected to the load support member (3) and installed in the installation part. There are no special restrictions on the structure or shape as long as the load support member (3) can be supported so as to be rotatable up and down, but in this embodiment, it is composed of a shaft member (61) and a fixed member (62).
[0053] The shaft support member (61) is composed of a pair of shaft support projections (611) that are arranged facing each other on one side and the other side of the fixed gear (51) and have shaft holes (612) formed therein. In addition, the shaft support member (61) is formed with a hinge bolt insertion hole (616) so that a hinge bolt (615) that is fastened to the shaft hole (512) of the fixed gear (51) is inserted therein.
[0054] The fixed member (62) is a component for fixing the main components that are coupled to the bearing member (61) to the installation part, and can be formed into various structures without any special restrictions depending on the type of the installation part (u), such as a massage chair, health care device, and bed.
[0055] For example, the fixed member (62) is composed of a connecting rod (621) that is connected to the bearing member and formed in a roughly 'L' shape, and a fixed plate (622) to which the connecting rod (621) is connected and fixed to the installation portion by a fastening member such as a bolt.
[0056] Meanwhile, an LED phototherapy device capable of adjusting the light irradiation position according to one embodiment of the present invention may be configured with a stopper unit (7) as a safety device to stably maintain a state in which a rod support unit (3) including a movable rod unit (2) is rotated at a specific angle by the operation of a rotary drive unit (5).
[0057] For example, the stopper part (7) is provided with a pin insertion hole (71) drilled in the bearing member (61) to selectively control the rotation of the fixed gear (51), a plurality of pin fixing holes (72) formed at a certain angle in the semicircular gear body (511), and a position fixing pin (73) inserted through the pin insertion hole (71) and then inserted into a specific pin fixing hole (72).
[0058] The stopper part (7) described above is inserted into a specific pin fixing hole (72) that is connected to the pin insertion hole (71) while the fixed gear (51) is rotated to a specific desired angle by the operation of the rotary drive part (5), so that even if the operation of the support rotation motor (53) is stopped, the rotary gear does not rotate, and thus the rotation of the fixed gear (51) is blocked, so that the position of the movable rod part (2) can be stably maintained without movement, so that light can be effectively irradiated to a specific location on the human body.
[0059] In addition, the LED phototherapy device capable of controlling the light irradiation position according to one embodiment of the present invention has a direction changing part (8) configured in the fixed support part (6) to change the overall arrangement direction of the rod support part (3) including the movable rod part (2).
[0060] The direction changing part (8) can be configured without any special restrictions on structure or shape as long as it can rotatably support the bearing member (61).
[0061] For example, the direction changing part (8) can be configured as a ball joint installed on one side and the other side of the connecting rod (621) of the fixed member (62) in a state in which the connecting rods are configured to be detachable from each other.
[0062] The ball joint is a device in which various known ball joints can be installed, and is composed of a ball portion (81) formed on the lower side of the connecting rod (621) and having a ball (812) protruding from the ball base (811), and a ball receiving portion formed on the upper side of the connecting rod and having a ball receiving groove into which the ball is inserted and received. Here, since the ball joint is a known mechanical element, the drawing regarding the detailed structure is omitted and is simplified.
[0063] In addition, the direction change part (8) can also be configured with a structure in which the connecting rods (621) of the fixed member (62) are configured to be detachable from each other, and an upper flange (not shown) and a lower flange (not shown) are installed on one side and the other side of the connecting rod, and a thrust bearing (not shown) is built in between the upper flange and the lower flange.
[0064] Meanwhile, an LED phototherapy device capable of adjusting the light irradiation position according to one embodiment of the present invention may be equipped with a light source angle adjustment unit (9) configured between the light source unit (1) and the moving rod unit (2) to adjust the angle of the light source unit.
[0065] For example, the light source angle adjustment unit (9) may be configured as a ball joint formed at the connection portion of the module base (11) of the light source unit (1) and the connecting rod (131) of the module fastening member (13).
[0066] The ball joint can be installed with various known ball joints, and can be composed of a ball part (not shown) in which a ball is formed on a ball base formed on a module base, and a ball receiving part (not shown) in which a ball receiving groove is formed on a connecting rod (131) and into which a ball is inserted and received.
[0067] Meanwhile, an LED phototherapy device capable of controlling a light irradiation position according to one embodiment of the present invention comprises an input unit (not shown) composed of a touch panel, buttons, etc. for inputting input signals for operating a light source unit (1), a load driving motor (43) of a load driving unit (4), and a support rotation motor (53) of a rotation driving unit (5), and a control unit (not shown) for controlling the operation of the light source unit (1), the load driving motor (43), and the support rotation motor (53) according to the input signals of the input unit.
[0068] Hereinafter, the operation of an LED phototherapy device capable of controlling the light irradiation position according to one embodiment of the present invention will be briefly described.
[0069] FIG. 5 and FIG. 6 are drawings for explaining the operating state of an LED phototherapy device capable of adjusting a light irradiation position according to one embodiment of the present invention, wherein FIG. 5 shows a state in which the direction is changed based on a direction changing unit, and FIG. 6 shows a state in which the direction is changed based on a light source angle adjusting unit. FIG. 7 is a drawing for explaining the usage state of an LED phototherapy device capable of adjusting a light irradiation position according to one embodiment of the present invention, and shows a state in which it is installed on a massage chair.
[0070] Referring to the attached drawings 1 to 7, when using an LED phototherapy device capable of adjusting a light irradiation position according to one embodiment of the present invention, a light source unit (1), a movable rod unit (2), a rod support unit (3), a rod drive unit (4), a rotation drive unit (5), and a fixed support unit (6) are assembled, and the manufacturer or user assembles the fixed support unit (6) to an installation unit (u) such as a massage chair.
[0071] After completing the installation in this way, when the user is seated on the massage chair and power is supplied to the light source unit (1), the LED module (12) of the light source unit (1) lights up and irradiates the therapeutic light toward the body part, thereby exerting a light therapy effect.
[0072] In the process of performing such light therapy, if the irradiation angle of the therapeutic light is to be adjusted, an external force can be applied to the ball joint applied as the angle adjustment unit (9) to adjust the angle of the module base (11), thereby changing the irradiation direction of the light.
[0073] And, in order to control the depth of penetration of therapeutic light into the skin tissue during the phototherapy process, the input unit is operated to operate the load driving motor (43) of the load driving unit (4), which rotates the pinion (42) to move the engaged rack (41), and the moving rod unit (2) is moved in conjunction. That is, when the load driving motor (43) is rotated in the forward or reverse direction, the moving rod unit (2) moves forward or backward, so that the light source unit (1) connected thereto can be brought into contact with or away from the skin, thereby controlling the depth of light irradiation.
[0074] Meanwhile, when the light irradiation position of the therapeutic light is to be changed in the vertical direction during the light therapy process, the input unit (not shown) is operated to operate the support rotation motor (53), which rotates the rotation gear (52) to rotate the engaged fixed gear (51), thereby linking the rod support unit (3). When the rod support unit (3) rotates, the movable rod unit (2) connected thereto rotates, so when the support rotation motor (53) is rotated in the forward or reverse direction, the movable rod unit (2) rises or falls, so the position of the light source unit (1) can be adjusted up and down.
[0075] In addition, in the case where the light irradiation position in the left and right direction of the therapeutic light is to be changed during the light treatment process, the left and right position of the light source unit (1) can be adjusted by rotating the rod support unit (3) to the left or right by applying a rotational force to the direction changing unit (8) to rotate it clockwise or counterclockwise.
[0076] The terms "include," "comprise," or "have" described above, unless otherwise specifically stated, imply that the corresponding component may be present, and therefore should be interpreted to include other components rather than excluding them. All terms, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention pertains, unless otherwise defined. Commonly used terms, such as terms defined in dictionaries, should be interpreted to be consistent with the contextual meaning of the relevant technology, and shall not be interpreted in an ideal or overly formal sense, unless explicitly defined herein.
[0077] Although the configuration and operation of an LED phototherapy device capable of controlling a light irradiation position according to one embodiment of the present invention described above have been described, this is exemplary, and it will be understood that a person having ordinary skill in the art can substitute and modify some of the above-described embodiments without departing from the technical spirit of the present invention.
[0078] Therefore, it should be understood that the scope of protection of the present invention extends to the invention described in the patent claims and equivalents thereof.
[0079] The present invention relates to an LED phototherapy device capable of adjusting the position of a light source in the forward / reverse direction and up / down direction and of adjusting the angle to achieve an accurate light irradiation effect and to improve convenience and compatibility in use. In addition to the use of phototherapy, the present invention can be applied to various devices or fields requiring movement of the position of a light source, such as a beauty device using light.
