[0036] Example

[0037] like Figure 1 As shown, this embodiment provides an ultrasonic imaging device 10, comprising:

[0038] A host 100, on which a socket 12 and a lighting device 200 are disposed, wherein the lighting device 200 is used to provide lighting for the socket 12;

[0039] An ultrasonic probe, which is connected to the socket 12;

[0040] A display 300, the display 300 is connected to the host 100;

[0041] The control panel 400 is connected to the host 100 and is disposed above the socket 12 and the lighting device 200 .

[0042] Since the control panel 400 is located above the socket 12 , it is difficult for the indoor light source to directly illuminate the socket 12 , making it difficult to plug the ultrasound probe into the socket 12 . In this embodiment, a lighting device 200 is provided on the host 100 , which can provide lighting for the socket 12 , thereby facilitating the lighting of the ultrasound probe socket 12 .

[0043] like Figure 1 As shown, the lighting device 200 and the socket 12 can be arranged on the same side of the outer periphery of the host 100. In other embodiments, the lighting device 200 can also be arranged above the socket 12 and at the bottom of the control panel 400. This embodiment does not limit the position of the lighting device 200, as long as the lighting device 200 can provide lighting for the socket 12 of the ultrasound probe.

[0044] Furthermore, if Figure 2 and 3 As shown, the host 100 includes a housing 11, and the lighting device 200 includes a substrate 21, a lampshade 22 and at least one LED light source 23, and a surface of the lampshade 22 opposite to the substrate 21 is a light emitting surface 224;

[0045] The base plate 21 is fixed in the housing 11 . A clamping portion 223 is protruded from the outer wall of the lampshade 22 . The clamping portion 223 is clamped between the housing 11 and the base plate 21 . One end of the lampshade 22 away from the base plate 21 protrudes from the housing 11 .

[0046] The light emitting surface 224 on the lampshade 22 protrudes from the housing 11 , and the light emitted by the LED lamp provides lighting for the vicinity of the socket 12 through the light emitting surface 224 .

[0047] In this embodiment, the base plate 21 is threadedly connected to the housing 11. In other embodiments, the base plate 21 and the clamping portion 223 may be fixed to the housing 11 by clamping, gluing, or other methods, and are not limited to threaded connection.

[0048] In one embodiment, if Figures 1 to 6 As shown, a lighting device 200 is used for lighting the probe socket 12 of the ultrasonic imaging device 10;

[0049] The lighting device 200 has a light-transmitting cavity, in which at least one LED light source 23 is arranged, and at least part of the inner wall of the cavity is distributed with a concave-convex structure; the light emitted from the LED light source 23 is refracted by the concave-convex structure to reach the outside of the cavity, so that the light-emitting angle of the lighting device 200 is greater than or equal to 180°.

[0050] In this embodiment, the lighting device 200 is provided with a concave-convex structure on the inner side of the light-transmissive cavity, and the light emitted by the LED light source 23 is refracted by the concave-convex structure, so that the light emitting angle of the lighting device 200 can be greater than or equal to 180°. The lighting device 200 is arranged near the socket 12 connected to the ultrasound probe, and can diffuse the small range light emitting angle of the LED light source 23 to a larger angle, provide ambient lighting for the socket 12, and facilitate the rapid insertion of the ultrasound probe into the socket 12.

[0051] After the concave-convex structure makes the light diverge, when looking directly at the lighting device 200, the light emitted from the LED light source 23 is not directly seen, but the uniform and soft lighting formed by multiple reflections and refractions of the concave-convex structure is obtained, which not only expands the lighting range, but also turns a single high-brightness light source into a soft ambient lighting.

[0052] Preferably, at least part of the inner wall of the cavity is evenly distributed with a concave-convex structure. There can be multiple concave-convex structures, such as protrusions / grooves with various shapes such as dot-shaped, spherical, wavy, and sawtooth-shaped cross-sections. The concave-convex structure can be one of the above-mentioned protrusions / grooves evenly arranged on the light-emitting surface 224, or the above-mentioned multiple protrusions / grooves are arranged as a group, and multiple groups are evenly arranged.

[0053] The shape of the cavity can be spherical, quasi-spherical, cylindrical or quasi-cylindrical, etc. Preferably, the inner wall of the cavity with a concave-convex structure is a curved surface, which is conducive to increasing the light-emitting angle of the lighting device 200.

[0054] The concave-convex structure is distributed at least on the light emitting surface 224 of the cavity where the light emitted by the LED light source 23 reaches. According to different shapes of the cavity, the concave-convex structure can also be distributed on the inner wall except the light emitting surface 224 to further expand the light emitting angle of the lighting device 200.

[0055] After the LED light source 23 emits light to the concave-convex structure, part of the light is refracted and part of the light is reflected, and finally the light is transmitted to the outside of the cavity. A reflective surface can be set on the inner wall of the cavity near the backlight of the LED light source 23 or the backlight, so that the scattered light entering the backlight of the LED light source 23 or the backlight is reflected to the outside of the cavity, thereby improving the brightness of the lighting device 200. As an example, the inner wall of the cavity near the LED light source 23 can be coated with a reflective material or a metal-plated reflective layer.

[0056] Furthermore, if Figure 3 As shown, the lighting device 200 includes a substrate 21 and a lampshade 22;

[0057] The LED light source 23 is arranged on the substrate 21, and the substrate 21 and the lampshade 22 enclose a cavity; the side of the lampshade 22 opposite to the substrate 21 is a light emitting surface 224, and a concave-convex structure is arranged on one side of the light emitting surface 224 in the cavity.

[0058] The substrate 21 and the lampshade 22 can be connected by threaded connection, adhesive connection, snap connection or other methods. The lampshade 22 can be spherical, quasi-spherical, hemispherical, cylindrical or quasi-cylindrical in various shapes. The lampshade 22 can be made of polycarbonate (PC), polymethyl methacrylate (PMMA), glass material or other materials.

[0059] Furthermore, the light emitting surface 224 is a plane, or the light emitting surface 224 is a curved surface convex in a direction away from the substrate 21 .

[0060] The light emitting surface 224 is a flat surface or a curved surface, and the concave and convex structures provided on the light emitting surface 224 can achieve the effect of diffusing light. Figure 8As shown, the arrow in the figure is a schematic diagram of the light path of the light, and the light-emitting surface 224 is a curved surface, which is conducive to increasing the light-emitting angle of the lighting device 200.

[0061] Furthermore, the concavo-convex structure includes spherical protrusions 221 or strip-shaped protrusions 222 evenly distributed on the light emitting surface 224 .

[0062] like Fig. 9 The figure shows a cross-sectional view perpendicular to the axial direction of a single spherical protrusion 221 and a strip-shaped protrusion 222 of the concave-convex structure, and a schematic diagram of the optical path of the light of the LED light source 23 passing through the single spherical protrusion 221 and the strip-shaped protrusion 222. The spherical protrusion 221 and the strip-shaped protrusion 222 can diffuse the light, and the uniform distribution of multiple spherical protrusions 221 or strip-shaped protrusions 222 on the light-emitting surface 224 can make the light pass through the lampshade 22 to obtain diffused light with uniform brightness, thereby providing good illumination for the ultrasonic imaging device 10.

[0063] Furthermore, the spherical protrusions 221 are distributed on the light emitting surface 224 in a continuous or spaced array.

[0064] The spherical protrusions 221 can be distributed in various ways. In a direction parallel to the substrate 21 , a portion of the spherical protrusions 221 can be arranged continuously or at intervals along the light emitting surface 224 to form a row of protrusions. Multiple rows of protrusions can be arranged continuously or at intervals on the light emitting surface 224 .

[0065] Alternatively, the plurality of spherical protrusions 221 may be grouped together to form a group of protrusions, and the plurality of groups of protrusions may be distributed continuously or at intervals on the light emitting surface 224 .

[0066] Preferably, in one embodiment, Figure 5 As shown, the spherical protrusions 221 are continuously distributed and cover the entire light emitting surface 224 , so that the lighting device 200 can provide uniform lighting.

[0067] like Fig. 9 An example of a cross section of a spherical protrusion 221 is provided. The spherical protrusion 221 may be a hemisphere, a 3 / 4 sphere, or a sphere of other proportions.

[0068] Furthermore, a plurality of LED light sources 23 are arranged on the substrate 21 at intervals along the first direction, and the concave-convex structure includes strip-shaped protrusions 222 evenly distributed on the light emitting surface 224, and the strip-shaped protrusions 222 are arranged continuously or at intervals on the light emitting surface 224 parallel to or perpendicular to the first direction.

[0069] like Figure 4 , 6As shown in FIG. 7 , multiple LED light sources 23 are arranged along a first direction, and strip-shaped protrusions 222 are arranged continuously or at intervals on a light-emitting surface 224 along the first direction or perpendicular to the first direction, so that the concave-convex structure of the light-emitting surface 224 can evenly diffuse the light emitted by multiple LED light sources 23 .

[0070] The plurality of LED light sources 23 are preferably evenly spaced apart and arranged on the substrate 21 along the first direction.

[0071] Preferably, the first direction is parallel to the length extension direction or the width extension direction of the light emitting surface 224 of the lampshade 22 . In other embodiments, the first direction may also have an angle with the length extension direction or the width extension direction of the light emitting surface 224 of the lampshade 22 .

[0072] As an example, the strip-shaped protrusions 222 may be arranged at intervals on the light emitting surface 224 along the first direction. In one embodiment, as shown in FIG. Figure 6 and 9 As shown, the cross section of the strip-shaped protrusion 222 is semi-cylindrical, the first direction is parallel to the length extension direction of the light emitting surface 224 of the lampshade 22, and the strip-shaped protrusions 222 are arranged at intervals along the first direction.

[0073] The strip-shaped protrusions 222 may also be arranged continuously on the light emitting surface 224 along the first direction. In another embodiment, as shown in FIG. Figure 7 and 9 As shown, the cross section of the strip-shaped protrusion 222 is triangular (tooth-shaped), the first direction is parallel to the width extension direction of the light-emitting surface 224 of the lampshade 22 , and the strip-shaped protrusions 222 are arranged at intervals along the first direction.

[0074] It can be understood that in other embodiments, the plurality of LED light sources 23 may also be evenly distributed on the substrate 21 , and are not limited to being distributed in rows along the first direction.

[0075] Furthermore, if Fig. 9 As shown, the cross section of the strip-shaped protrusion 222 perpendicular to the axis is tooth-shaped or circular-shaped, and one or more of the tooth-shaped strip-shaped protrusions 222 and the circular-shaped strip-shaped protrusions 222 are evenly arranged and distributed on the light-emitting surface 224 .

[0076] The different strip-shaped protrusions 222 can be distributed in various combinations, as long as they can be evenly distributed on the light-emitting surface 224. The strip-shaped protrusions 222 of the lampshade 22 can form multi-angle refraction surfaces. After the light is emitted from the LED light source 23 to the multi-angle refraction surfaces, part of the light is refracted to form dense light with different emission angles to penetrate the outer surface of the lampshade 22, thereby achieving the desired uniform brightness of the lighting light.

[0077] Furthermore, the rated power of a single LED light source 23 is less than or equal to 1 watt.

[0078] Typically, the rated power of the low-power LED light source 23 is between 0.1 watt and 1 watt, the rated power of the medium-power LED light source 23 is between 1 watt and 5 watts, and the rated power of the high-power LED is 5 watts or more.

[0079] The luminous angle of the lighting device 200 can be further expanded by the concave-convex structure in the cavity. If a reflective surface is set at other positions in the cavity, the light scattered to the reflective surface can also be reflected to the light-emitting surface 224, thereby improving the brightness of the lighting device 200. Therefore, in combination with the above structure, the lighting device 200 can realize the illumination of the socket 12 by selecting a low-power LED light source 23. The low-power LED light source 23 has low power consumption and small size, and the lighting device 200 is miniaturized and does not occupy the space of other components of the ultrasonic imaging device 10. A number of low-power LED light sources 23 can be evenly distributed on the substrate 21. As an example, in this embodiment, three 0.1-watt LED light sources 23 are evenly arranged on the substrate 21. There is no limit on the number of LED light sources 23, so that the lighting of the sockets 12 of different ultrasonic imaging devices 10 can be adapted.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
