Description

UV light emitting diode curing device

technical field

The utility model relates to an ultraviolet light-emitting diode curing device, in particular to a UV hardening glue that uses an ultraviolet light (UV) light-emitting diode (LED) light source to cure and coat on the nails of hands and feet of human bodies, animals and pets. installation.

Background technique

As solid-state lighting or LED lighting is widely adopted in different lighting applications, these new types of lighting have become one of the important solutions for a green energy world. Among the many LED types, a new family of LEDs capable of emitting UV radiation or light of shorter wavelengths than visible light, known as UVLEDs, has also been developed for industrial applications.

While it is true that UV rays are generally harmful to human health because UV is more energetic and more dangerous than visible light, UV has special applications in industry. Certain industrial applications use UV rays for the curing of certain liquids, and the use of such UV rays has shown advantages in printing techniques and produces protective layers on industrial products. Conventional UV lamps have also been used in cosmetics to cure acrylic liquid or acrylic glue for easy nail art and nail protection.

Conventional UV lamps and bulbs are commonly used in known UV devices for curing certain UV hardening adhesives. The U.S. Patent No. 4731541 discloses a UV device, which uses a traditional UV lamp to expose the UV hardened glue coated on the nails to the UV lamp when the human hand is in the casing. A protective layer is formed on the nails of the human hand. U.S. Patent No. 5,130,551 adopts similar concepts of UV hardening glue and traditional UV lamps, but has an improved design that can accept the nails of people's hands and feet. U.S. Patent No. 6518583 discloses a UV device for human hands, which also uses UV lamps, but uses more UV bulbs, thus increasing the UV irradiation area to cover multiple fingers at a time. In U.S. Patent No. 6,762,425, a UV device is disclosed for curing gels coated on people's fingernails and toenails, and because the UV chamber and the UV lamp are specifically designed to treat the hands received therein It can harden not only the UV curing glue applied on the fingernails but also the UV curing glue on the toenails at one time.

The main concern of using such UV devices on human hands and feet is the risk of skin cancer caused by long-term exposure of human skin to UV rays from these conventional UV lamps or bulbs of the device for short or long periods of time. Known to be strongly associated with this danger is the fact that traditional UV lamps generally emit three types of UV light with reference to skin protection and are UVA, UVB and UVC. Of the three UV rays, UVC is the most damaging and energetic.

In view of the above description, it is necessary to provide a UV curing device that can overcome the shortcomings of the known prior art and provide a green solution that is more environmentally safe for humans. In addition, there is also a need to provide a UV curing device to facilitate the creation of nail art and nail protection.
