Gel nail curing device

Abstract

The present disclosure relates to a gel nail curing device comprising a housing having internal space to accommodate the hand or foot where gel nail is applied, lighting part comprising a plurality of LEDs for curing said gel nail by emitting visible light toward the hand or feet; and controlling part controlling said LEDs of said lighting part, wherein said lighting part emits visible light reacting with a photoinitiator contained in said gel nail to promote curing of said gel nail.

What is claimed is: 
     
         1 . A gel nail curing device comprising:
 a housing having internal space to accommodate the hand or foot where gel nail is applied;   a lighting part comprising a plurality of LEDs for curing said gel nail by emitting visible light toward the hand or feet; and   a controlling part controlling said LEDs of said lighting part;   wherein said lighting part emits visible light reacting with a photoinitiator contained in said gel nail to promote curing of said gel nail.   
     
     
         2 . The gel nail curing device of  claim 1 , wherein said lighting part emits visible light of 450 nm or less excluding ultraviolet light to prevent skin damage from ultraviolet light. 
     
     
         3 . The gel nail curing device of  claim 1 , wherein said lighting part comprising:
 a first lighting unit that emits visible light in a first wavelength range that is 450 nm or less excluding ultraviolet light; and   a second lighting unit that emits infrared light in a second wavelength range that comprises a wavelength of 800 nm.   
     
     
         4 . The gel nail curing device of  claim 1 , wherein said controlling part controls said LEDs in a PWM(Pulse Width Modulation) method to reduce skin damage and increase a lifetime of said LEDs. 
     
     
         5 . The gel nail curing device of  claim 1 , wherein said gel nail comprises bis (2,4,6-trimethylbenzoyl)-phenylphosphineoxide,
 wherein said lighting part emits a visible light that cures said bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide.   
     
     
         6 . The gel nail curing device of  claim 1 , wherein said housing comprising:
 an inner housing having said internal space and said lighting part;   an upper cover covering an upper portion of said inner housing and having an open hole formed at the center;   a lower cover covering a lower portion of said inner housing and having a space to which a pedestal is coupled;   a top cover coupled to said open hole to cover a top surface of said upper cover; and   a pedestal for the hand or foot to be placed and detachably combined with said lower cover;   wherein an upper surface of said inner housing comprising an air hole through which a heated air is discharged,   wherein said upper cover and said top cover are spaced apart from each other by a predetermined distance so that said heated air discharged from said air hole escape to the outside of said housing.
