Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention relates generally to an ultraviolet (UV) equipment, and more particularly to an innovative one which generates UV radiation by LED in lieu of UV lamp, and also applies ultraviolet onto a gel for curing purpose. 
         [0002]    An UV equipment  1  used for pseudo-nail gel (e.g.: UV gel, UV resin) generally applies a lamp  11  to yield radiation of UV wavelength for the curing of UV gel or UV resin, as shown in  FIG. 1 . The typical UV equipment  1  can realize the curing of the UV gel or UV resin, but there are still some shortcomings: 1: the lamp  11  in a radiation state will surely generate heat source; since the lamp  11  is mounted in the UV equipment  1 , the heat source generated by the lamp  11  is difficult to be dispersed, leading to overheating or poor heat elimination; 2, the lamp  11  generates light in a radiative way, so when the lamp  11  radiates onto the UV gel or UV resin, the curing time is longer and effect is poorer; in the event of incomplete curing, a longer radiation time will be required, leading to waste of both time and electrical resources, along with higher electricity price; 3, when the lamp  11  is activated, it&#39;s difficult to control efficiently the curing time of the UV gel or UV resin; 4, the lamp  11  has a shorter service life, so new product are often purchased with a relatively higher cost; for these reasons, more efforts have to be made for resolving the aforementioned problems. 
         [0003]    Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy. 
         [0004]    Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products. 
       BRIEF SUMMARY OF THE INVENTION 
       [0005]    The primary objective of the UV equipment of the present invention is to replace conventional lamp by LED units, since the heat source generated by LED units is much less than that of lamp, making it possible to reduce the heat source and resolve the heat elimination problem. 
         [0006]    The second objective of the UV equipment of the present invention is that the light path of LED units is concentrated, so the curing effect of UV gel or UV resin is better, helping to save power and reduce the electricity price. 
         [0007]    The third objective of the UV equipment of the present invention is that the UV path of LED units is concentrated, enabling to control efficiently the curing time of UV gel or UV resin and avoid incomplete curing. 
         [0008]    The fourth objective of the UV equipment of the present invention is that the replacement frequency and cost of the units are relatively lower thanks to the longer service life of the LED units. 
         [0009]    The UV equipment of the present invention is mainly characterized by that, the LED units are used for radiation of UV wavelength onto a gel, which is cured after a period of reaction; if the gel is applied to pseudo-nail, it&#39;s possible to attach it closely to the real nail; if the gel is applied to tooth mould or pseudo-tooth, a protective layer will be formed from gel curing and covered onto the surface of the tooth mould or pseudo-tooth.
