In one embodiment, the control unit 4 may also be connected to the illumination unit 3 through another connection manner, and drive the illumination unit 3 to illuminate different brightness or lighting time, so as to adapt to different nail polish gels and curing effects achieved in different scenes.

Referring to fig. 4, fig. 4 is a schematic diagram showing that the LED lamp panel of this application is lighted, and as shown in fig. 4, the LED lamp panel is fully distributed with an array of closely arranged LED lamp beads, the LED lamp beads are UV LED lamp beads, and each lamp bead or each partial region of the LED lamp beads can be independently controlled. After the LED driver receives the illumination unit coordinate system data sent by the core controller through the I2C bus, the LED driver controls the LED lamp panel to work, the LED lamp panel works, only the LED lamp beads corresponding to the nail region are in a working state, the ultraviolet light is ensured to irradiate the nail region only, other regions of the hand are not in contact with the ultraviolet light, and the hand is not damaged by the ultraviolet light. The black LED lamp beads in the LED lamp bead array shown in fig. 4 represent the lamp beads that have been driven to light, and the white LED lamp beads represent the lamp beads that do not need to work. The connection mode of the LED driver and the LED lamp panel is not limited, and the LED driver and the LED lamp panel can be adjusted in a user-defined mode according to a connection object in practical application.

In one embodiment, the minimum unit of the driving control of the LED lamp panel is an independent area, not a lamp bead. The method for driving the LED lamp panel to control the independent area to be turned on and turned off is the same as the method for driving the LED lamp panel to control the lamp beads to be turned on and turned off, and the method is not repeated here.

In one embodiment, as shown in fig. 7, the illumination unit 3 further includes a shielding plate, the shielding plate is disposed between the LED lamp panel of the illumination unit 3 and the supporting unit 5, and the shielding plate is connected to the LED lamp panel.

If the LED lamp panel is an LED lamp panel with independently controllable lamp beads or independent areas, the LED lamp panel is equivalent to a single light source, a shielding plate is arranged below the LED lamp panel and above the supporting unit 5, as shown in fig. 7, the shielding plate is a liquid crystal panel 6, the liquid crystal panel 6 is connected with the LED lamp panel, the liquid crystal panel 6 is controlled to be transparent in the nail area, and black or other opaque colors are displayed in the non-nail area.

Referring to fig. 8, fig. 8 is a schematic diagram illustrating a mask formed on the liquid crystal panel 6 according to an embodiment of the present invention, when the liquid crystal panel 6 is operated, as shown in fig. 8, the liquid crystal panel only displays transparency in the nail region, and displays black or other opaque colors in the non-nail region, so as to form the mask, so that ultraviolet rays cannot penetrate through the black or other opaque portions of the liquid crystal panel, and the display of the LED lamp panel of the illumination unit 3 is controlled, and the liquid crystal panel only irradiates the nail region. The shade formed by the liquid crystal panel 6 can be changed with different users or hands at different positions where the users are placed.

The application provides a beautiful first lamp control method, can accurately discern the nail region to control illumination unit 3 and only cover the nail region when shining, even the user frequently carries out beautiful first, can not cause the suntan of hand yet. The nail lamp of this embodiment uses very simply, and the user need not to take extra operations such as gloves when using, and the use is noninductive, only needs to put into the cavity internal specific position that shell 1 formed with the hand, also need not specially cooperate, does not need to change the use habit of current nail lamp, and it is very convenient to use.

The application provides a pair of first beautiful lamp, the irradiation area that can accurate control illumination unit 3 realizes working as required, only needs the production that fairly few energy is used for ultraviolet ray, both the energy saving can avoid first beautiful lamp inside temperature to rise again, and the user does not have uncomfortable sense at illumination unit 3's working process, is suitable for extensive using widely.
