The outer side of the light-emitting cavity is inlaid with a transparent glass 7, and the inner side of the light-emitting cavity is fixedly connected to an ultraviolet lamp board 12. When the ultraviolet lamp board 12 is powered on, the ultraviolet rays emitted can pass through the transparent glass 7, so that the illuminator body 1 emits ultraviolet rays.

[0026] A paper feed port 13 is provided in the middle of the top of the inner cavity of the luminous cavity. The paper feed port 13 is in an inverted eight shape. The spacing at the bottom of the paper feed port 13 and the distance between the two conveying rollers 14 are adapted to the thickness of the shading paper.

When the light-shielding paper is removed, the user presses the outlined border to remove the engraved affected area pattern. The user uses the remaining part of the shielding paper to shield the light-transmitting glass 7. The shape of the ultraviolet rays emitted through the light-transmitting glass 7 is the same as the shape of the affected area, preventing the ultraviolet rays from affecting the user's normal skin cells.

[0030] In some embodiments of the present application, the vertical ball screw structure 16 includes a ball screw 1 movably connected to the engraving cavity, a vertical ball nut threadedly connected to the ball screw 1, and a motor 1 that drives the ball screw 1 to rotate; the horizontal ball screw structure 17 includes a ball screw 2 movably connected to the vertical ball nut, a motor 2 fixedly connected to the vertical ball nut, and a horizontal ball nut 18 threadedly connected to the ball screw 2.

[0036] To sum up: this handheld UVB light instrument is mainly for patients with skin diseases such as vitiligo and psoriasis. When in use, the user uses a fixed box to clamp a piece of intact shading paper, and places the fixed box into the engraving cavity, and the box cover 10 is located on the side of the box body 9 close to the puncture needle 15. The user starts the light-emitting device and uses the visual sensor 8 to collect the shape of the skin lesions on the affected area. The collected results are displayed on the display screen 4. The user outlines the illumination range and illumination shape on the display screen 4. The data processing and analysis module controls the operation of the depiction module according to the drawing results. The depiction module outlines the illumination range and illumination shape on the shading paper through the puncture needle 15. After the depiction is completed, the user takes out the shading paper and removes the outlined pattern, and puts the remaining part of the shading paper into the light-emitting cavity through the paper feed port 13. The conveying roller 14 conveys the shading paper until the shading paper is completely conveyed into the light-emitting cavity. At this time, the shading paper blocks the light-transmitting glass 7, and the ultraviolet lamp board 12 is energized. The ultraviolet rays emitted by the ultraviolet lamp board 12 are irradiated to the affected area through the cut part of the shading paper, and the shape of the ultraviolet beam emitted by the light-emitting device is the same as the shape of the affected area, realizing personalized treatment and preventing ultraviolet rays from affecting the patient's normal cells.
