Figure 6 is an enlarged view of the concave lamp cup in Figure 5.

As shown in FIG. 1, this creative embodiment is a high illuminance ultraviolet light LED nail lamp structure 100, which includes a housing 10 and an LED light source module 20.

As shown in Figure 2, the housing 10 can include a bottom plate 101; a side plate 102; and a top plate 103. The hollow shell has an open hollow space 11 and an opening 12, and the hollow space 11 allows the palm or the sole of the foot to extend through the opening 12 and be placed therebetween.

The LED light source module 20 is an ultraviolet light source. In order to facilitate the irradiation of fingernails, the LED light source module 20 is generally arranged in the housing 10 and located on the upper side of the housing 10, that is, inside the top plate 103 of the housing 10, and the LED light source module 20 is projected from top to bottom. Light.

As shown in FIG. 3, the LED light source module 20 includes: a circuit board 21 and a plurality of ultraviolet LEDs 22.

For the circuit substrate 21, in order to facilitate the inspection of the circuit substrate 21 during production or subsequent maintenance, the circuit substrate 21 may be a modular design, that is, the circuit substrate 21 may be composed of one or more substrates. The commonly used circuit substrate 21 may be an aluminum circuit substrate or a PCB circuit board.

A plurality of ultraviolet LEDs 22 are electrically connected and fixed to the circuit substrate 21, and the ultraviolet LEDs 22 can be dispersed and arranged on the circuit substrate 21 at equal intervals to achieve the effect of large-area irradiation.

As shown in FIGS. 4 and 5, each UV LED 22 includes: a bracket 221; an LED chip 222; a silicon rubber 223; and a lens 224.

The bracket 221 has a concave lamp cup 225 and at least two electrodes 226. In most cases, the bracket 221 has a heat-conducting base 227, and the concave lamp cup 225 is a part of the heat-conducting base 227. The thermally conductive base 227 may be made of a material with good heat dissipation characteristics, such as metal materials such as copper, tin, steel, or iron.

As shown in Figure 6, the concave lamp cup 225 is used to place the LED chip 222, and the inner wall 228 of the concave lamp cup 225 can help reflect the light generated by the LED chip 222 on the bottom surface 229 of the concave lamp cup 225 The UV LED 22 is emitted to increase the illuminance, so that a better lighting effect can be obtained and the curing time of the UV hardening adhesive can be shortened. The depth of the concave lamp cup 225 is d. When d is less than 1 mm or the angle θ between the wall surface 228 and the bottom surface 229 of the concave lamp cup 225 is greater than 25°, the illuminance of the UV LED 22 can be effectively increased.

The silicone lens 224 has the characteristics of high refractive index, high temperature resistance, high insulation, high chemical stability, high light transmittance and high reliability, so it can also avoid the materials produced by traditional packaging materials due to high temperature. Deterioration and the phenomenon of brightness decay caused by it.

In the application of this embodiment, the finger or toe whose nail has been coated with ultraviolet hardening glue can be extended from the opening 12 into the hollow space 11 of the housing 10; then the LED light source module 20 is turned on to make the LED light source module 20 Emit ultraviolet light to cure the ultraviolet light hardening glue. Since UV-curing adhesives are usually resins containing photosensitizers, they can generate active free radicals or ionic groups after absorbing ultraviolet light to initiate polymerization, cross-linking and grafting reactions. Therefore, UV-curing adhesives can change from liquid to liquid in a few seconds. Solid state, so that the coated UV-curing glue is fixed on the nail. In addition, because this embodiment can provide the LED nail lamp structure 100 with high illuminance ultraviolet light, the curing time of the ultraviolet hardening glue can be shortened, thereby achieving the effect of reducing the cost.
