DETAILED DESCRIPTION OF THE INVENTION

In the following description of the present invention, a detailed description of known functions and configurations which are obvious to those skilled in the art will be omitted when it may unnecessarily make the subject matter of the present invention rather unclear.
FIG. 1 illustrates an exemplary view of the gel nail curing device of the present invention and FIG. 2 illustrates a disassemble view of the gel nail curing device of the present invention. As illustrated in FIGS. 1 and 2, the gel nail curing device 100 comprises a housing 110, a lighting part 120, and controlling par 130.
The housing 110 has internal space to accommodate the hand or foot where gel nail is applied. The housing 110 comprises an inner housing 111, an upper cover 112, a lower cover 113, a top cover 114, and a pedestal 115.
The inner housing 111 has the internal space and the lighting part 120. The upper surface of the inner housing 111 comprises an air hole through which a heated air is discharged. The upper cover 112 covers an upper portion of the inner housing 111 and has an open hole formed at the center. The lower cover 113 covers a lower portion of the inner housing 111 and has a space to which the pedestal 115 is coupled. The top cover 114 is coupled to the open hole to cover a top surface of the upper cover 112. The pedestal 115 is for the hand or foot to be placed and detachably combined with the lower cover 113.
The upper cover 112 and the top cover 114 are spaced apart from each other by a predetermined distance so that the heated air discharged from the air hole escapes to the outside of housing 110.
The lighting part 120 comprises a plurality of LEDs for curing the gel nail by emitting visible light toward the hand or feet. The lighting part 120 emits visible light reacting with a photoinitiator contained in the gel nail to promote curing of the gel nail. The lighting part 120 emits visible light of 450 nm or less excluding ultraviolet light to prevent skin damage from ultraviolet light.
The controlling part 130 controls the LEDs of the lighting part 120. The controlling part 130 controls the LEDs of the lighting part 120 by PWM (Pulse Width Modulation) method to reduce skin damage and increase lifetime of LEDs.
FIG. 3 illustrates an exemplary view of the lighting part and controlling part of the present invention. As illustrated in FIG. 3, the lighting part comprises a first lighting unit 121 and a second lighting unit 123.
The first lighting unit 121 emits visible light in a first wavelength range that is 450 nm or less excluding ultraviolet light. The first wavelength range is used to cure the gel nail. The visible light of the first wavelength range includes the visible light wavelength that reacts with the photoinitiator contained in the gel nail.
The second lighting unit 123 emits infrared or far-infrared light in a second wavelength range. The infrared or far-infrared light of the second wavelength range extend capillaries to help blood circulation and cell tissue formation and prevent skin aging. The second wavelength range may comprise a wavelength of 800 nm.
Far-infrared ray refers to a long wavelength of infrared rays. An infrared ray is a type of electromagnetic wave having a longer wavelength than a red region of a visible light, and a shorter wavelength is called a near-infrared ray. It is invisible to the naked eye, is well absorbed by the material, and has resonance and resonance action on the molecules of the organic compound. In addition, light is generally well reflected when the wavelength is short, and when the wavelength is long, it is absorbed well when it reaches the object, so the penetration is strong and the human body is also warmed by this infrared light. This heat helps to eliminate germs that cause various diseases, and it enlarges the capillaries and helps blood circulation and cell tissue formation. In addition, when it comes in contact with moisture and protein molecules that make up the cell, it is effective to prevent various diseases such as aging, metabolism promotion and chronic fatigue by activating the cell tissue by shaking the cells 2,000 times per minute. In addition, it has effects of promoting sweating, relieving pain, removing heavy metals, sleeping, deodorizing, sterilization, prevention of fungus growth, dehumidification, and air purification.
In a preferred embodiment, bis (2,4,6-trimethylbenzoyl)-phenylphosphine oxide may be used as a photoinitiator of gel nails. The lighting part of the present invention can cure the gel nail by emitting visible light wavelength range that reacts with bis (2,4,5-trimethylbenzoyl)-phenylphosphine oxide. The bis (2,4,5-trimethylbenzoyl)-phenylphosphine oxide may be Omnirad 819 manufactured by IGM Resin Co., but the present invention is not limited thereto.
Bis (2,4,5-trimethylbenzoyl)-phenylphosphine oxide can be cured by ultraviolet light. However, since it has a photosensitivity to a wavelength longer than ultraviolet rays, it also can be cured by the wavelength of visible light emitted by the lighting part of the present invention. In a preferred embodiment, the lighting part of the present invention can emit visible light of 405 nm to 420 nm to cure bis (2,4,5-trimethylbenzoyl)-phenylphosphine oxide.
The present invention can minimize skin damage by curing the gel nail using visible light which is emitted by the first lighting unit instead of ultraviolet light.
In addition, the present invention expands capillary blood vessels by emitting infrared or far-infrared light to help blood circulation and cell tissue formation and prevent skin aging.
As described above, the present invention can simultaneously emit different wavelengths of light in the first lighting unit for emitting visible light for preventing skin damage and the second lighting unit for emitting infrared or far-infrared light for preventing skin aging.
In addition, by PWM controlling the LEDs of the lighting part, it is possible to reduce the power consumption and minimize the skin damage by reducing the time of skin exposure to the light emitted from the first illumination unit for gel nail curing. On the other hand, if the amount of light is adjusted by adjusting the number of LEDs to be turned on/off, there is a problem that the irradiation area irradiated by the LEDs is changed. However, PWM control of the LEDs can maintain the irradiation area constant.
In addition, the present invention can cure the gel nail within a short time by emitting a wavelength of visible light that reacts with the photoinitiator contained in the gel nail.
Further, the present invention can extend the lifetime of the LEDs by lowering the temperature of the LEDs by emitting the heated air through the top cover
The protective scope of the present invention is not limited to the description and expression in embodiments specifically described above. Furthermore, the protective scope of the present invention could not also be limited due to obvious changes or replacements in the technical field of the present invention.
