[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0023] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an interactive light, comprising:

[0024] The lamp body 1 has a receiving cavity therein. The shape and size of the lamp body 1 can be determined according to actual needs and are not limited here.

[0025] A PCB board 2 is accommodated in the accommodating cavity, and a plurality of LED light sources 3 are arranged on the PCB board 2. Each LED light source 3 has an optical axis 4. The central axis of the light emitted by the LED light source 3 is the optical axis 4. In a feasible implementation manner, the plurality of LED light sources 3 are on the same horizontal plane, and the plurality of optical axes 4 are also arranged in parallel. In other feasible implementation manners, the plurality of LED light sources 3 can be on a curved surface, so that the extension directions of the plurality of optical axes 4 are not parallel, which is not limited here.

[0026] The first shading member is arranged on the PCB board 2. In the radial direction of the optical axis 4, the first shading member is arranged around each LED light source 3. The first shading member is used to block the light emitted by the LED light source 3 from passing through the first shading member and reaching the area where the adjacent LED light source 3 is located.

[0027] The light-diffusing plate 6 is arranged in the accommodating cavity. The light-diffusing plate 6 is arranged facing the LED light source 3. The shape of the light-diffusing plate 6 can be determined according to the arrangement of the plurality of LED light sources 3. When the plurality of LED light sources 3 are arranged in a horizontal array, the light-diffusing plate 6 as a whole is also approximately flat. When the plurality of LED light sources 3 are arranged in a curved array, the light-diffusing plate 6 is also a curved structure. The projection of each LED light source 3 in the direction of the optical axis 4 falls on the light-diffusing plate 6. The light-diffusing plate 6 is used to achieve uniform brightness of the light-emitting surface of the entire light-diffusing plate 6, reduce brightness changes and light spots, and create a more natural and comfortable environment that is more in line with the human eye's perception of brightness.

[0028] The second shading member is formed on the light emitting plate 6. The projection of each LED light source 3 in the direction of the optical axis 4 is offset from the second shading member. The second shading member is used to further improve the boundary between different LED light sources 3 and reduce the light escaping and generating cross-light after the light is emitted from the light emitting plate 6.

[0029] The above embodiment prevents light crosstalk by setting a first shading member and a second shading member around the LED light source 3. The light emitted by the LED light source 3 will not diffuse to the area where the adjacent LED light source 3 is located, thereby ensuring the integrity and independence of a single pixel.

[0030] Furthermore, the first shading member includes a first shading strip 5, one end of the first shading strip 5 is in contact with the PCB board 2, and the other end of the first shading strip 5 is in contact with the light-diffusing plate 6. In a feasible implementation, the first shading strip 5 is made of an elastic material, one end of which is bonded to the light-diffusing plate 6 or integrally formed with the light-diffusing plate 6, and the other end is pressed against the PCB board 2 to produce elastic deformation, thereby preventing light leakage from the bottom of the first shading strip 5.

[0031] Preferably, the first shading strip 5 and the light-diffusing plate 6 are integrally formed, which simplifies the production process and eliminates the assembly process, thereby improving production efficiency and reducing product production costs.

[0032] The first shading strip 5 is a strip structure with a certain width and height. The width of the first shading strip 5 is maintained in a certain range, for example, greater than 1 mm and less than 2 mm, so as to avoid the width of the first shading strip 5 being too small, and the light will still pass through the first shading strip 5, causing the problem of light cross-talk. The width of the first shading strip 5 should not be too large, otherwise it will occupy the lighting space of the LED light source 3, while saving production materials, thereby reducing the production cost of the product.

[0033] The height of the first shading strip 5 is maintained within a certain range, for example, the height is less than 5 mm. The height of the first shading strip 5 cannot be too large. If it is too large, the size of the interactive lamp will be increased and the display effect will be affected.

[0034] Preferably, at least two first shading strips 5 are provided between two adjacent LED light sources 3, and the two first shading strips 5 are parallel to each other, so that the interference between the adjacent LED light sources 3 can be better isolated, thereby achieving a better anti-cross-lighting effect.

[0035] Reference Figure 2 As shown, the gap between two adjacent first shading strips 5 is smaller than the gap between the first shading strips 5 located on the opposite sides of the LED light source 3. The gap between two adjacent first shading strips 5 should not be too small, otherwise it may cause light transmission, and should not be too large, otherwise it will increase the size of the interactive light and make the distance between the two LED light sources 3 too large, affecting the display effect.

[0036] In the embodiment provided by the utility model, the second shading member includes a second shading strip 7, and the second shading strip 7 is attached to the side of the light-diffusing plate 6 that is away from the LED light source 3. The projection of the second shading strip 7 in the direction of the optical axis 4 falls on the first shading strip 5. The first shading strip 5 and the second shading strip 7 overlap in the direction of the optical axis 4. This will not affect the propagation effect of the light generated by the LED light source 3, and the second shading strip 7 will not block the light propagation path and affect the display effect.

[0037] Preferably, the light-diffusing plate 6 is a white light-diffusing plate 6 and the second shading strip 7 is black, which increases the contrast and further improves the boundaries between different lights, thereby improving the aesthetics of the interactive light.

[0038] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
