The wood lamp provided by the present application has an overall appearance as shown in fig. 1, and is mainly composed of a light shield 100 and a wood lamp body 200. The light shield 100 is connected to the wood lamp body 200 by means of threads, snap-fit or magnetic attraction, as shown in fig. 1 and 2. The wood light may also include a hand-held controller 300 as shown in fig. 9.

The light shield 100 has an opening at each of the front and rear ends thereof, and the openings are disposed to face each other. Wherein the rear end opening is connected to the wood lamp body 200; the wood lamp body 200 is provided therein with a light source module, and light emitted therefrom is irradiated from the front opening of the light-shielding cover 100. The rear portion of the light shield 100 is less likely to be deformed and can be stably connected to the wood lamp body 200. The front portion of the light shield 100, which contacts the irradiated object (e.g., the patient's skin), is relatively flexible and is more likely to deform than the rear portion of the light shield. In this patent, the terms "easily deformable" and "strongly deformable" mean that the deformation occurs to a greater extent when the same external force is applied.

Various different forms can be adopted to realize different deformation performances of the light shield:

(1) the light shield is made of the same material, but the thickness is different. The material behind the light shield is thick and is not easy to deform; the material in front of the shade is thin and easily deformed.

(2) In the form of a mask body + support member. The support member is located at the rear of the light shield body and provides support for the light shield in this position. Because the supporting component is not easy to deform, the part of the light shield is also not easy to deform.

In the above-described (2) form, the support member may be located in the light shield main body inner space; or be completely covered by the shade main body, in which case the support member is a skeleton of the shade. By adopting the form of the light shield main body and the supporting component, the simulated dark environment can be effectively formed when observing lesions of parts with large fluctuation of human bodies, and the high-quality images can be acquired under various use conditions.

The light shield body 110 is made of a flexible light shielding material, such as black or dark cloth. One end of the light shield body 110 is an elastic band structure, which can be conveniently sleeved on the periphery of the support member 120, as shown in fig. 5. The other end of the light shield main body 110 is in a corrugated shape, and the end of the light shield main body is 5-20 cm more than the end of the supporting part 120, so that when the curved part of the human body is observed, the more part can completely cover the peripheral drop, and a closed light shielding environment is formed.

The supporting component is made of flexible material with better strength and hardness, and can be silicon rubber, rubber and plastic material with hardness of more than 50. The support member is a generally straight or angularly extending cylindrical member. In fig. 5, the support members 120 are trumpet shaped with one nozzle in tandem. Wherein, the back mouth of pipe has a circle of mounting groove 121, and wood lamp body's shell 211 opening edge has a circle of protruding structure of complex outward with it, and the mounting groove uses with protruding structure cooperation, is a buckle form. The entire light shield 100 is attached to the wood lamp body 200 by slightly stretching and expanding the attachment groove 121 and then attaching the light shield to the boss structure. When the wood lamp is horizontally buckled, the front part of the light shield main body 110 can deform, but the supporting part 120 can not collapse and deform, and the rear part of the light shield main body 110 is supported, so that the light shield is prevented from being freely bent to block the observation sight. The front nozzle of the support member 120 is flat and is located at a position where the intensity and uniformity of the light emitted from the light source module 240 are optimal. The inner wall of the support member 120 is black or dark.

In addition to the support members 120 shown in fig. 6 with the complete tube wall, the support members may be made as support members 130 shown in fig. 7, or as support members 140 shown in fig. 8. The wall of the support member 130 has a plurality of openings 132, which saves material and reduces weight. The rear nozzle of the support member 130 is provided with a mounting groove 131. The support member 140 is composed of a support ring 141 and a plurality of support bars 142, the support ring 141 is adjacent to the rear end opening of the shade cloth body 110, the base portions of the support bars 142 are attached to the support ring 141, and the end portions of the support bars 142 extend toward the front end opening of the shade cloth body 110 with a distance greater than 5 cm from the edge of the front end opening.
