Description

Technical Field

[0001] This utility model relates to the technical field of Wood's lamps, and specifically to a novel Wood's lamp. Background Technology

[0002] The structural defects of traditional Wood's lamps include: reliance on darkrooms. Conventional Wood's lamps need to be used in a completely dark environment. Because the light shield is a rigid, fixed cylindrical structure (such as ABS plastic), it cannot fit tightly against the curve of the skin, causing ambient light to enter through the gaps (light leakage rate >15%). The fluorescence signal under sunlight is completely drowned out. In addition, patients need to enter a dedicated darkroom, which leads to low efficiency in outpatient clinics and makes home self-examination impossible.

[0003] The detection blind spots and misdiagnosis rate are high. It uses a single light source and visual observation, and the irradiation range is small (diameter <3cm). It is difficult to cover areas such as the scalp and between the fingers. In addition, doctors judge the fluorescence color with the naked eye (such as bright green / yellow-green), and the difference in experience leads to a misdiagnosis rate of over 30%.

[0004] It has limited functionality, lacks image recording capabilities, and its light shield is fixedly connected to the lamp body, making disinfection inconvenient and unable to adapt to different body parts.

[0005] Despite attempts to upgrade some existing products, certain defects remain, including insufficient mechanical structure, lack of dynamic compression design, and gaps still existing after pressing; the single camera has a limited field of view (coverage angle <120°). Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a novel Wood's lamp that can achieve: rapid replacement to fit different parts; dynamic compression to fit curved surfaces; and 360° imaging without blind spots.

[0007] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0008] A novel Wood's lamp includes a vertically connected handle and a connecting rod. A mounting box and a connecting plate are fixedly connected to both sides of the connecting rod, and a light source assembly is fixedly connected to the outside of the connecting plate. An external light-shielding assembly is provided around the light source assembly. The light source assembly includes a mounting base and a light source inside it. A display mechanism is embedded inside the mounting base. The external light-shielding assembly includes a light shield and an elastic layer at its outer end.

[0009] Furthermore, the mounting base and the connecting plate are arranged horizontally. The mounting base is a cylindrical base with a conical outward-expanding lamp cavity inside. The lamp cavity irradiation end is outward-expanding. The surface of the mounting base near the connecting plate is provided with an annular mounting groove. The inner wall of the conical lamp cavity is provided with a gold-plated reflective layer. The annular mounting groove contains a neodymium magnet array.

[0010] Furthermore, the display mechanism includes a set of ring cameras located on the inner end surface of the mounting base, surrounding the outside of the light source.

[0011] Furthermore, the light shield includes a hemispherical surrounding shield and a conical expanding shield. The elastic layer is a wave-shaped layer and is disposed on the surface of the irradiation end of the conical expanding shield. A hollow inflatable silicone sealing strip is disposed on the edge of the irradiation end of the conical expanding shield.

[0012] Furthermore, the outer layer of the sunshade is made of black PEEK engineering plastic, and the inner layer is made of matte aluminum oxide coating. The hemispherical enclosure is connected to the mounting base via a magnetic structure.

[0013] Furthermore, the elastic layer is made of medical-grade liquid silicone, and a thin-film piezoresistive pressure sensor is integrated at the edge.

[0014] Furthermore, the mounting box incorporates a miniature vortex fan and a thermal grease filling layer.

[0015] Furthermore, the display mechanism is connected to an image preprocessing board.

[0016] As can be seen from the above technical solution, the beneficial effects of this utility model are:

[0017] In this invention, the gold plating layer inside the mounting base improves the utilization rate of UVA and reduces energy consumption, while the conical cavity improves the uniformity of irradiation.

[0018] In actual use, the light shield and elastic layer of this device enable direct detection of sunlight environment, while the ring camera is responsible for 360° imaging and fits the conical cover with a curved surface. The detachable light shield supports high temperature and high pressure sterilization and is easy to operate. Attached Figure Description

[0028] like Figures 1-3 As shown, a novel Wood's lamp includes a handle 1 and a connecting rod 2 connected vertically. A mounting box 3 and a connecting plate 4 are fixedly connected to both sides of the connecting rod 2, respectively. A light source assembly 5 is fixedly connected to the outside of the connecting plate 4. An outer light shielding assembly 6 is provided around the light source assembly 5. The light source assembly 5 includes a mounting base 7 and a light source 8 inside it. A display mechanism 9 is also embedded inside the mounting base 7. The outer light shielding assembly 6 includes a light shield 10 and an elastic layer 11 at its outer end.

[0029] In this embodiment, the mounting base 7 and the connecting plate 4 are arranged horizontally together. The mounting base 7 is a cylindrical base with a lamp cavity corresponding to the lamp source 8 inside. The irradiation end of the lamp cavity is conical and outwardly oriented. The surface of the mounting base 7 near the connecting plate 4 has an annular mounting groove corresponding to the light shield 10. The mounting base 7 is made of 6061 aluminum alloy with anodized black treatment. The inner wall of the conical lamp cavity is provided with a gold-plated reflective layer (reflectivity > 95%), and the annular mounting groove contains a neodymium magnet array for adsorbing the light shield 10. The gold plating layer in the mounting base 7 increases the UVA utilization rate from 60% to 92%, reduces energy consumption by 50%, and the conical cavity makes the irradiation uniformity > 90% (compared to only 70% in traditional designs).

[0030] In this embodiment, the display mechanism 9 includes a set of ring-shaped cameras located on the inner surface of the mounting base 7, and surrounding the outside of the lamp source 8. The lamp source is a 365nm UVA LED (Seoul Semiconductor STW8Q13H), specifically arranged with a central array of 6 LEDs and a total power of 8W. The ring-shaped camera module in the display mechanism 9 is a Sony IMX415 (1 / 2.8"). The camera uses a CMOS sensor (supporting 4K@30fps), consisting of eight sensors arranged in a uniform ring array (covering a 360° viewing angle). A bandpass filter (center wavelength 440nm, bandwidth ±10nm, cutoff depth OD6) is placed on the front surface of the camera lens. The camera is protected by a sapphire glass cover (for UV protection) and a nano-oleophobic coating. The display mechanism 9 enables full-view coverage, and the 360° ring view eliminates blind spots, such as areas covered by hair. The OD6 filter ensures ambient light transmittance <0.01% and a signal-to-noise ratio >35dB under sunlight. The sapphire cover and nano-oleophobic coating effectively improve durability, enhance UV protection by 10 times, and prevent coating peeling.

[0031] In this embodiment, the light shield 10 includes a hemispherical surrounding shield and a conical outer expansion shield fitted with the mounting base 7. The elastic layer 11 is set as a wave layer and is located on the surface of the irradiation end of the conical outer expansion shield. The edge of the irradiation end of the conical outer expansion shield is provided with biocompatible silicone containing an antibacterial coating and is a hollow inflatable design. When pressed, it expands to enhance the seal, thereby preventing light leakage and reducing the feeling of pressure on the skin.

[0032] The outer layer of the light shield 10 is made of black PEEK engineering plastic (99.9% light blocking rate), and the inner layer is made of matte aluminum oxide coating. It has a split design. The hemispherical surrounding cover is magnetically attached to the mounting base 7, while the conical outer cover is detachable and replaceable to adapt to different detection parts. In actual use, it can block ambient light. The magnetic structure facilitates quick disassembly and cleaning. The quick magnetic structure of the light shield 10 enables quick replacement of detection heads, such as face and scalp adapters. The combination of double-layer materials blocks 99.9% of ambient light (it can still work under 2000 lux illuminance).

[0033] In this embodiment, the elastic layer 11 is specifically made of medical-grade liquid silicone (Shore hardness 20A, light transmittance ≤0.1%), with a waveform pleated design (compression stroke 0-15mm) and a thin-film piezoresistive pressure sensor integrated at the edge. It can dynamically conform to the skin surface during use. When the pressure is >0.3N, the light source is automatically triggered. The waveform compression of the elastic layer 11 forms a negative pressure adsorption, and the light leakage rate of the curved surface is <0.1%. The light source is automatically turned on and off when the pressure is >0.3N to avoid ineffective irradiation and achieve energy saving.

[0034] In this embodiment, the mounting box 3 is lined with a Mu metal layer to suppress camera signal interference, and the lamp cavity is equipped with a miniature vortex fan (wind speed 0.5m / s) and thermal grease filling (temperature control ≤45℃). The power isolation is a DC-DC isolation module (ripple <10mV).

[0035] The installation box 3 is equipped with an integrated AI processor (such as Rockchip RK3588) to facilitate automatic calibration of lesion areas;

[0036] When using this device, turn on the light source 8, place the light shield 10 in the outer light shield assembly 6 into the annular mounting groove on the surface of the mounting base 7, then press the light shield 10 against the skin position to be detected, the light source 8 illuminates the skin, and the display mechanism 9 transmits the image of the illuminated position.

[0037] The image preprocessing board required in this device is a Xilinx Artix-7 FPGA (XC7A50T) for real-time splicing of 8-channel camera footage (delay <50ms).

[0038] The main processor is Rockchip RK3588 (quad-core A76 + quad-core A55, NPU6TOPS), which runs AI fluorescence analysis algorithms. The supporting communication interface is USB3.0 Type-C + Wi-Fi6 (peak transmission rate 9.6Gbps). In addition, the required fluorescence enhancement algorithm, AI lesion analysis system and other systems are existing publicly available technologies, which will not be described in detail here.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
