Description

LED module plate and light irradiation device including the same

[0001] The present invention relates to an LED module plate and a light irradiation device including the same, and more particularly, to an LED module plate that irradiates light that can be effectively applied to beauty, therapy, and treatment, and a light irradiation device including the same.

[0002] Research is actively underway on devices and methods for irradiating the human body with artificial light for purposes such as beauty, therapy, and treatment. Mercury lamps were previously the primary light source for these devices. However, for environmental and energy efficiency reasons, LEDs are increasingly replacing mercury lamps.

[0003] In the case of light irradiation devices that use LED elements as light sources, there are structural differences in the light source arrangement method compared to light irradiation devices that use existing mercury lamps as light sources. In the case of light irradiation devices that use existing mercury lamps as light sources, maintenance was carried out by replacing the lamps that had reached the end of their lifespan. While LED elements have a relatively long service life compared to mercury lamps, there is a problem that excessive maintenance costs occur because the entire LED panel must be replaced when the lifespan of the LED element applied to the light irradiation device has ended.

[0004] Meanwhile, although LED devices generate less heat than conventional mercury lamps, a ventilation system must be installed to appropriately control the temperature inside the light irradiation device to ensure that the user is exposed to an appropriate temperature. In the case of conventional light irradiation devices that use mercury lamps as a light source, a method of directly blowing air on the human body was mainly applied. However, in the case of LED devices that generate less heat than mercury lamps, applying a ventilation system that directly blows air on the human body may cause discomfort to the user due to noise or dryness.

[0005] One aspect of the present invention is to provide an LED module plate capable of effectively irradiating light to a human body while maintaining a comfortable indoor environment, and a light irradiation device including the same.

Accordingly, the shapes of each element shown in the drawings may be emphasized or exaggerated for a clearer explanation.

[0035]

[0036] Hereinafter, a light irradiation device according to one aspect of the present invention will be described in more detail with reference to FIGS. 1 to 6.

[0037]

[0038] As illustrated in FIGS. 1 to 6, a light irradiation device (1) according to one aspect of the present invention may include a body (10) having a receiving space (115) formed inside along an up-and-down direction for receiving a user's human body, and a door (20a, 20b) mounted on the body (10) so that the user can enter and exit the receiving space (115). The doors (20a, 20b) may be provided as a pair and arranged in a symmetrical shape, and the entrance may be opened as the doors (20a, 20b) move to an open position, and the entrance may be closed as the doors (20a, 20b) move to a closed position.

[0039] The body (10) may include a body frame (100) provided to provide support by being arranged in a standing structure and a body cover member (115) provided to form the outer shape of the body (10) on the outside of the body frame (100), and a plurality of LED module plates (31) arranged to partition a receiving space (115) may be arranged on the body frame (100). The plurality of LED module plates (31) arranged on the body frame (100) may be arranged horizontally parallel to each other and may be arranged continuously in the vertical direction, and a ventilation slit (S) described below may be formed between the LED module plates (31) adjacent to each other in the vertical direction to provide a path for air to move. A first flow space (113) is formed between the body cover member (115) and the LED module plate (31) arranged on the body frame (100), and a ventilation unit (500a, 500b) for discharging air from the first flow space (113) to the outside may be arranged inside the first flow space (113). In terms of effective discharge of air, it is preferable that one or more ventilation units (500a, 500b) are provided, and in consideration of effective circulation of air, it is preferable that the ventilation units (500a, 500b) are fixedly arranged on the body frame (100) on the upper side of the first flow space (113).

[0040] The upper side of the body frame (100) is provided with an upper opening (110) that connects the receiving space (115) with the outside, and when the ventilation unit (500a, 500b) is operated, outside air can be introduced into the receiving space (115) through the upper opening (110). In addition, when the ventilation unit (500a, 500b) is operated, air introduced into the receiving space (115) can be introduced into the first flow space (113) through a ventilation slit (S) formed between a plurality of LED module plates (31) arranged on the body frame (100).

[0041] The doors (20a, 20b) may be provided to enable opening and closing of an entrance formed on one side of the body (10). The method of moving the doors (20a, 20b) for opening and closing the entrance is not particularly limited, and various methods such as a sliding method and a rotating method may be applied. However, in terms of usability and space, it may be preferable that the doors (20a, 20b) are each axially coupled to one side of the body (10) so that they can move between an open position and a closed position by rotation as shown in FIGS. 1 and 2. Meanwhile, the doors (20a, 20b) according to one aspect of the present invention may include a case in which they are automatically opened and closed using a driving force such as a motor or hydraulic pressure.

[0042] The doors (20a, 20b) may each include a door frame (200a, 200b) that functions as a skeleton of the doors (20a, 20b) and a door cover member (215a, 215b) that is provided to form the outer shape of the doors (20a, 20b) on the outside of the door frame (200a, 200b), and a plurality of LED module plates (32, 33) that are arranged to partition a receiving space (115) may be arranged on the door frames (200a, 200b), respectively. The plurality of LED module plates (32, 33) arranged on the door frames (200a, 200b) may be arranged horizontally parallel to each other and may be arranged continuously in the vertical direction, and a ventilation slit (S) described below may be formed between the LED module plates (32, 33) that are vertically adjacent to each other to provide a path for air to move. Second flow spaces (220a, 220b) are formed between the door cover members (215a, 215b) and the LED module plates (32, 33) arranged on the door frame (200a, 200b), respectively, and as the ventilation unit (500a, 500b) operates, air introduced into the receiving space (115) can be introduced into the second flow spaces (220a, 220b) through the ventilation slits (S) formed between the plurality of LED module plates (32, 33) arranged on the door frame (200a, 200b).

[0043] When the door (20a, 20b) moves to a position where it closes the entrance, a first flow hole (110a, 110b) and a second flow hole (210a, 210b) can be formed through the two sides of the body frame (100) and each end of the door frame (200a, 200b) that are in contact with each other and have a shape corresponding to the corresponding position. The drawing shows four first flow holes (110a, 110b) and four second flow holes (210a, 210b) formed in a shape extending vertically at each of the two side ends of the body frame (100) and each end of the door frame (200a, 200b), but the shape and number of the first flow holes (110a, 110b) and the second flow holes (210a, 210b) of the present invention are not necessarily limited thereto, and the shape and number of the first flow holes (110a, 110b) and the second flow holes (210a, 210b) may be applied in various modified forms. When the door (20a, 20b) is open, the first flow space (113) and the outside are connected by the first flow hole (110a, 110b), and the second flow space (220a, 220b) can be connected by the second flow hole (210a, 210b) to the outside. Meanwhile, when the door (20a, 20b) is closed, the two side ends of the body frame (100) in which the first flow hole (110a, 110b) and the second flow hole (210a, 210b) are formed are positioned in close contact with each other at each end of the door frame (200a, 200b), so that the first flow hole (110a, 110b) and the second flow hole (210a, 210b) are in communication with each other, and the first flow space (113) and the second flow space (220a, 220b) can be in communication with each other through the communicated first flow hole (110a, 110b) and second flow hole (210a, 210b).Although not shown in the drawing, packing parts provided using a flexible material may be provided around the first flow hole (110a, 110b) and the second flow hole (210a, 210b), and when the door (20a, 20b) is moved to the closed position, these packing parts are in close contact with each other, so that air can be effectively prevented from escaping to the periphery of the first flow hole (110a, 110b) and the second flow hole (210a, 210b), respectively.

[0044] As illustrated in FIGS. 4 and 6, when the ventilation unit (500a, 500b) is operated, air is introduced into the receiving space (115) through the upper opening (110), and the space introduced into the receiving space (115) can be introduced into the first flow space (113) or the second flow space (220a, 220b) through the ventilation slit (S) formed between the plurality of LED module plates (31, 32, 33). Meanwhile, the air introduced into the second flow space (220a, 220b) can be introduced into the first flow space (113) through the first flow holes (110a, 110b) and the second flow holes (210a, 210b) that are connected to each other, and the air introduced into the first flow space (113) can be discharged to the outside through the ventilation unit (500a, 500b). The light irradiation device (1) according to one aspect of the present invention has a structure in which air is naturally drawn in from above the user due to a difference in back pressure, so that it can effectively prevent unpleasant sensations such as noise or dryness that may be caused by directly spraying air to the user. In addition, the light irradiation device (1) according to one aspect of the present invention has a structure in which air can move through ventilation slits (S) formed between a plurality of LED module plates (31, 32, 33), so that it can effectively cool the heat generated from the LED when irradiating light, so that it can effectively suppress excessive heat from being transmitted to the user, and can also effectively extend the life of the LED element.

[0045] Meanwhile, the light irradiation device (1) according to one aspect of the present invention may further include a jog switch member (400) that is disposed on the inner surface of the body frame (100) forming the receiving space (115) and is operated by a user. Although three jog switch members (300) provided in a flat cylindrical shape are illustrated in FIG. 2, the shape and number of the jog switch members (400) of the present invention are not necessarily limited thereto, and as long as it is a means by which a user can intuitively control the light irradiation device (1), the shape and number are not particularly limited. As the user operates the jog switch member (400), at least one of the irradiation position, irradiation area, and irradiation intensity of light irradiated from the LED module plate (300) can be adjusted. That is, as the user manipulates the jog switch member (400), the height of the light irradiated from the LED module plate (300) can be adjusted as illustrated in FIG. 14, or the area of ​​the light irradiated from the LED module plate (300) can be adjusted as illustrated in FIG. 15, and although not illustrated in the drawing, the wavelength and intensity of the light irradiated from each LED module plate (300) can also be adjusted. When the light irradiation device (1) is irradiated, a user in the receiving space (115) may have difficulty in accurately operating the device due to glare, etc., but the light irradiation device (1) according to one aspect of the present invention has a jog switch member (400) that can intuitively adjust at least one of the irradiation position, irradiation area, or irradiation intensity of the light, thereby more effectively improving the convenience of use.
