Description

Light therapy system {LIGHTING THERAPY SYSTEM}

The present invention relates to a light therapy system, and more particularly, to a light therapy system for radiating high-efficiency treatment light to a user.

Recently, LED lighting has become a popular trend. An LED, that is, a light emitting diode, refers to a device that generates injected minority carriers (electrons or holes) by using a p-n junction structure of a semiconductor and emits a predetermined light by recombination thereof. There are red light emitting diodes, green light emitting diodes using GaP, etc., blue light emitting diodes using an InGaN/AlGaN double hetero structure, and the like.

A recent light emitting device for lighting implements white light by combining a light emitting diode chip and a phosphor mold. For example, by disposing a phosphor on top of a light emitting diode chip that emits blue light, white is obtained by the blue light emission of the light emitting diode chip and the yellow green or yellow light emission of the phosphor. That is, white light is implemented by a combination of a blue light emitting diode chip made of a semiconductor component emitting light of 430 nm to 480 nm wavelength and a phosphor that generates yellow-green and yellow light using blue light as an excitation source.

Recently, demand for visible light LEDs and invisible light LEDs for sterilization or treatment purposes, as well as light emitting devices for lighting that emit white light, is on the rise.

That is, it is widely known that when light is irradiated on a living body, cells are activated by the optical action, and it is irradiated with low energy to the extent that there is no damage to the living body cells to induce activation of the physiological function of the living body, thereby relieving pain and affecting the affected area. Methods of imparting therapeutic effects, such as rapid regeneration of cells and elimination of causative diseases, are widely practiced. At this time, it is already known that different treatment effects appear depending on the wavelength of the light used.

For example, a 633nm wavelength LED is known to improve the skin's natural healing power and create healthy and beautiful skin through the production of collagen and elastin, a 415nm blue light LED is known to be effective in treating inflammatory diseases, and an 830nm wavelength LED is known to be effective in skin cell regeneration and wound healing after sunburn. In addition, although there are side effects of excessive exposure to ultraviolet rays, it is known that vitamin D is synthesized in the body and has a bactericidal action.

However, the LED has a disadvantage in that the object and purpose of treatment are limited because it is composed of a short wavelength with a relatively small half-width. Accordingly, in Prior Art Document 1, a plurality of 'multi-wavelength LED modules' and 'multi-wavelength LED modules' that simultaneously or selectively output a plurality of wavelengths for each wavelength are mounted, and are divided into a plurality of sectors so that each sector can be rotated. It consists of a head, a support arm that supports the head and adjusts the position and angle of the head, a body that fixes and supports the support arm, and is provided with a power supply unit that supplies power to the 'multi-wavelength LED module', Through this configuration, it is possible to output a selective wavelength or a plurality of wavelengths through a multi-wavelength LED module without having to replace heads equipped with LEDs of different wavelengths.

However, prior art document 1 has a structure in which elements of different wavelengths are arranged on one side of a narrow head, so the intensity and density of light are significantly reduced compared to the short-wavelength head composed only of short-wavelength LEDs, resulting in a decrease in the treatment effect. are doing

Referring to the drawings, the light therapy system 1000 according to an embodiment of the present invention includes a sensor unit 100, a control unit 200, a light source unit 300, an input unit 400, and a housing 500 in which they are disposed. and may further include an output unit 600.

First, as shown in FIGS. 2 and 3 , the sensor unit 100 is disposed inside the housing 500 to sense environment information and a user's condition. 2 and 3 show that the sensor unit 100 is disposed on the inner wall on the right side, but it is apparent that the position of the sensor unit 100 is not limited thereto. Furthermore, as shown in FIG. 4, the sensor unit 100 includes the sensor unit 100, a human body sensor 110, a radar sensor 120, an infrared sensor 130, a camera 140, and a temperature sensor 150. It is done by

The human body detection sensor 110 may use an infrared motion detection sensor, and is also called an infrared human body detection sensor or a PIR motion sensor. The human body sensor 110 detects a change in light when a person or animal passes by and detects a movement of a person or the like in the set space R. Here, the setting space refers to a space inside the housing 500 in which the light source unit 200 emits light. When a user is not detected by the human body sensor 110, light emission of the treatment light emitted from the light source unit 300 may be turned off.

The radar sensor 120 detects how the user is located inside the housing. The radar sensor 120 may generate information about a user, which is an object inside the housing 100, using radio waves. The radar may include an electromagnetic wave transmitter, an electromagnetic wave receiver, and at least one processor electrically connected to the electromagnetic wave transmitter and electromagnetic wave receiver, processing a received signal, and generating data about a user object based on the processed signal.

At this time, the radar may be implemented in a pulse radar method or a continuous wave radar method in terms of the radio wave emission principle. The radar may be implemented in a frequency modulated continuous wave (FMCW) method or a frequency shift keyong (FSK) method according to a signal waveform among continuous wave radar methods. The radar may detect an object based on a Time of Flight (TOF) method or a phase-shift method through electromagnetic waves, and may detect the location of the user, which is the detected object, and the distance to the detected object. . Therefore, as will be described later, it is possible to turn on the LED corresponding to the user's position in the light source unit 300 and increase the light output of the corresponding LED in proportion to the user's distance.

The infrared sensor 130 detects infrared emission from the user's body. Since the user has body temperature, infrared rays are emitted inside the body. The infrared sensor 130 detects minute changes in body heat such as pain or nerve damage in a specific part of the body captured by the camera 140. Accordingly, as will be described later, the light source unit 300 increases only the light output of the corresponding LED to irradiate a specific part of the human body. This increases the treatment effect and reduces unnecessary power consumption.

On the other hand, the temperature sensor 150 is a sensor that detects a temperature change and converts it into a measurable signal, and measures the temperature of the internal space of the housing 500 or the user in a non-contact manner. At this time, the non-contact temperature sensor may use an infrared thermometer or a method of measuring the amount of radiation emitted from the user's surface. The temperature sensor 150 also serves to sense the temperature inside the housing 500 so that the temperature inside the housing 500 is set according to the mode selected by the input unit 400 .

As shown in FIGS. 2 and 3 , the light source unit 300 is disposed to emit treatment light toward the inside of the housing 500 . At this time, as shown in FIG. 2, the light source unit 300 includes a first light source unit 300a, a second light source unit 300b, a third light source unit 300c, a fourth light source unit 300d, and It may consist of a fifth light source unit 300e. However, it is needless to say that the area of each light source unit may be smaller or larger than that shown in the drawings for entry into the housing or provision of a window.

Each light source unit is attached to the inner surface (inner wall) of the housing 500 and emits light under the control of the controller 200. In FIG. 3 , the four light source units 300b, 300c, 300d, and 300e exemplify the application of infrared rays to the user P.

At this time, each of the light source units 300 is composed of a plurality of infrared LEDs 310, ultraviolet LEDs 320, and visible light LEDs 330 to emit light suitable for the treatment purpose alone or in combination. In this case, in order to reduce power consumption, it is preferable that any two of the infrared LED 310, the ultraviolet LED 320, and the visible light LED 330 are designed to be disposed on one PCB.

Furthermore, as described above, the light source unit 300 may turn on only the LEDs disposed in the direction in which light is emitted to the user among the plurality of LEDs according to the detection of the sensor unit 100 . That is, as shown in FIG. 3, only the LEDs disposed in the central regions of the four light source units 300b, 300c, 300d, and 300e are turned on to reduce light concentration and power consumption. In addition, since linear light distribution toward the user is important for the LED used in this case, there is no need to insert a lens for side light distribution, so that the LED manufacturing cost can be reduced.

To this end, referring to FIG. 5 , the control unit 200 according to an embodiment of the present invention includes a light output control module 210, a mode output control module 220, and a variable output module 230.

As described above, the light output control module 210 accurately determines the location of the user according to the detected value of the radar sensor 120 and emits light according to the location. ) turn on the LED. At this time, light emission is suppressed according to a value previously input by the input unit 400 in a body part where light emission is to be suppressed according to the treatment purpose. In addition, the input unit 400 selects any one mode selected from hair loss treatment mode, skin treatment mode, joint treatment mode, growth promotion mode, vitamin synthesis mode, rest mode, sleep mode, skin stimulation mode, and automatic mode according to the treatment purpose. can be entered. Here, the automatic mode refers to a mode in which a preset visible light or big visible light is irradiated, but the irradiation light is changed in the middle due to a change in infrared rays emitted from the human body due to the above-mentioned pain or the like. Meanwhile, the input unit may be installed in the door 510 .

Similarly, the variable output module 330 plays a role of changing the light emission output or differently setting the light emission wavelength according to the detected user's set body part. This is because the treatment effect may be increased when the emission wavelength is light having one peak wavelength, and the treatment effect may be increased when the light has a plurality of peak wavelengths.

Also in this case, the variable output module 330 applies the maximum light output to the light concentration area to enable intensive light therapy. Thereafter, the variable output module 330 may suppress the light saturation phenomenon due to the concentration of light by applying the light emitting output in the form of a pulse or having a rest period (gap) of a certain period during irradiation.

In addition, the variable output module 330 may control different lights or lights with different outputs to be irradiated to the front and back or right and left sides of the user. At this time, when the user moves inside the housing, LEDs radiating (on) different lights or different outputs may be changed due to the real-time sensing value of the sensor unit. At this time, the output unit 600 may output an alarming or guide signal in response to a change in light output and a change in position, etc. in the form of sound.

Referring to FIG. 7 , the sensor unit 100 detects the user's location, and the third light source unit 300c and the second light source unit 300b turn off the LEDs irradiated toward the user's upper side d2 and direct them toward the user ( d1) Only the irradiated LED is turned on. At this time, when the arm pain is detected by the infrared sensor, the light emission output of the LED in the region corresponding to the user's arm is maximized to enable intensive phototherapy.

On the other hand, the housing 500 may be configured as a closed type that seals the inside from the outside by forming a wall as shown in FIGS. 2 and 3, or may be configured as an open type (not shown) that surrounds and accommodates a part of the body. have. In the case of an open type, a component for detecting body movement among sensor units may be omitted.

Hereinafter, a light therapy system according to another embodiment of the present invention will be described. 8 is a conceptual diagram of a light therapy system according to another embodiment of the present invention.

In this embodiment, the same reference numerals are assigned to the same components as in the previous embodiment.

In this embodiment, a door 510 for entry and exit is installed in the housing 500 . Accordingly, the area of the first light source unit 300a' is smaller than the space for the door 510. Accordingly, a separate light source unit or a reflector is installed on the inner surface 520 of the door to prevent wasteful irradiation of light. In addition, it is also preferable that at least two of the six surfaces constituting the housing 500 form closed surfaces that are not open, and a reflector is installed thereto to prevent wasteful irradiation of light.

In addition, at this time, it is also preferable to control the condensing or reflecting direction of light by creating an angle or curvature in the reflector. Accordingly, a light condensing part (not shown) or an avoiding part (not shown) for discharging light to the outside of the housing may be formed on the reflector according to light condensing or reflection direction control.

Hereinafter, a light therapy system according to another embodiment of the present invention will be described. 9 is a conceptual diagram of a light therapy system according to another embodiment of the present invention. In this embodiment, the same reference numerals are assigned to the same components as in the previous embodiment.

In this embodiment, the indicator 530 is created in the upper housing 500 of the first light source unit 300a'. As described above, since the light source unit emits visible light in addition to invisible light, the emitted light may also serve as an indicator. Therefore, as in the present embodiment, it is preferable to provide an indicator 530, which is a separate window, to confirm the current state of phototherapy.

At this time, the indicator 530 transmits not only red light or blue light when the visible light and invisible light, which are therapeutic lights, are formed in a wide band, but also visible light for a separate non-therapeutic purpose to inform the progress of the operation through the indicator 530, so that various information is transmitted through the indicator 530 through which it can be recognized from the outside. Furthermore, when the sleep mode is input through the above-described input unit 400, only invisible light may be irradiated to the inner lower portion of the housing, and visible light may be emitted only to the outside so as to pass through the indicator.

As described above, preferred embodiments of the present invention have been disclosed in the present specification and drawings, and although specific terms have been used, they are only used in a general sense to easily explain the technical content of the present invention and help understanding of the present invention. However, it is not intended to limit the scope of the present invention.
