Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.

[0042] Light emitting assemblies are widely used in robots. For example, light emitting assemblies can be applied to the head of a robot, arranged at positions such as ears, eyes or mouth, to interact with users and indicate information by changing the color of light emitted by the light emitting assembly; light emitting assemblies can also be applied to the torso of a robot to display robot state data and the like.

[0043] In related technologies, the light beams emitted by the light source in the robot light emitting device are directly emitted to the light emitting wall, and such light emitting design is prone to cause uneven light emission.

[0044] To solve the above technical problems, as shown in Figure 1 and Figure 2 , embodiments of the present application provide a light emitting assembly 100 mainly used in robots, which comprises a light emitting piece 110, a light dispersing piece 120 and a light homogenizing piece 130.

[0045] The light emitting piece 110 has a light emitting side 113. The light emitted by the light emitting piece 110 is emitted after passing through the light dispersing piece 120 and the light homogenizing piece 130. The light emitted by the light emitting piece 110 with concentrated irradiation angles is dispersed into soft parallel diffuse reflection light with multiple irradiation angles and wide irradiation range after passing through the light dispersing piece 120 and the light homogenizing piece 130.

[0046] Referring to Figure 2 , the light emitting piece 110 comprises a mounting plate 112, and a plurality of LED lamps 111 are arranged on the mounting plate 112. The mounting plate 112 is a PCB circuit board, and the plurality of LED lamps 111 are electrically connected to the mounting plate 112 respectively.

[0047] In some embodiments, as shown in Figure 2 , the LED lamps 111 are arranged on one side of the mounting plate 112 to form the light emitting side 113 of the light emitting piece 110.

[0048] In some embodiments, the LED lamps 111 are arranged on opposite sides of the mounting plate 112 to form two light emitting sides 113 of the light emitting piece 110, and the light emitting side 113 of the LED lamps 111 on each side is correspondingly provided with the light dispersing piece 120 and the light homogenizing piece 130.

[0049] In some embodiments, the mounting plate 112 is connected with an external control chip, so as to control the color change of the plurality of LED lamps 111 or to coordinately control the brightness of each LED lamp 111, and to display the information expression of the robot by changing the color and brightness of the LED lamps 111, such as that blue represents a working state, green represents a charging state, red represents a warning state, and the like.

[0050] The shape of the mounting plate 112 can be changed according to the part of the robot to which the light-emitting assembly 100 is actually applied. For example, when the light-emitting assembly 100 is applied to the ear part of the robot, the edge profile of the mounting plate 112 is close to the shape of the ear.

[0051] Correspondingly, the light emitted by the light-emitting member 110 passes through the light-uniform member 130 and is emitted, and the light-uniform member 130 has a light-out wall for transmitting light to the outside. The shape of the light-out wall can also be changed according to the part of the robot to which the light-emitting assembly 100 is actually applied. For example, when the light-emitting assembly 100 is applied to the ear or eye part of the robot, the edge profile of the light-out wall is close to the shape of the ear or eye, so that the light-emitting assembly 100 can play a role in simulating human ears or eyes.

[0052] Of course, in some embodiments, the light-emitting assembly 100 can also not simulate the shape of the human organ. For example, when the light-emitting assembly 100 is arranged at the ear part of the robot, the light-emitting assembly 100 can be provided in a spherical shape.

[0053] In some embodiments, as shown in Figures 2 to 4 The light-uniform member 130 is connected with the light-emitting member 110 and defines a mounting space between the light-emitting member 110 and the light-uniform member 130, and the light-diffusing member 120 is arranged at the light-out side 113 of the light-emitting member 110 and located between the light-emitting member 110 and the light-uniform member 130 and mounted in the mounting space.

[0054] It can be understood that when light propagates in a medium, scattering phenomenon occurs. Generally, in air, the scattering intensity of light is relatively weak, while in a solid, the scattering intensity is usually stronger due to more frequent interaction between photons and matter.

[0055] As shown in Figures 2 to 4 The light-diffusing member 120 and the light-emitting member 110 form a first scattering space P1, and the light-diffusing member 120 and the light-uniform member 130 form a second scattering space P2. The side of the light-diffusing member 120 close to the light-emitting member 110 has a first light-diffusing structure 1211, and the side of the light-diffusing member 120 close to the light-uniform member 130 has a second light-diffusing structure 1212. The light emitted by the light-emitting member 110 passes through the first scattering space P1, the light-diffusing member 120, the second scattering space P2 and the light-uniform member 130 in sequence and is emitted.

[0056] The light emitted by the light emitting member 110 first passes through the first scattering space P1, the light propagates in the air and scatters for the first time, then passes through the light scattering member 120, the light propagates in the solid and scatters for the second time, then passes through the second scattering space P2, the light propagates in the air and scatters for the third time, and finally passes through the light homogenizing member 130, the light propagates in the solid and scatters for the fourth time, thereby improving the scattering efficiency of the light and making the light emitted by the light homogenizing member 130 uniform and soft.

[0057] Meanwhile, the light scattering member 120 of the present application also has the first light scattering structure 1211 and the second light scattering structure 1212, which can improve the light scattering capacity of the light scattering member 120, improve the light scattering efficiency, and make the light emitted by the light homogenizing member 130 uniform and soft.

[0058] In some embodiments, with reference to Figure 4 , the light scattering member 120 comprises a light-transmitting wall 121 which is arranged spaced apart from the light emitting member 110 and the light homogenizing member 130.

[0059] It can be understood that the scattering angle of the light is random.

[0060] When the light passes through the gap between the light-transmitting wall 121 and the light emitting member 110, the distance between the light-transmitting wall 121 and the light emitting member 110 is short, most of the light can enter the light-transmitting wall 121, and a small part of the light diverges to the four directions to form stray light. Similarly, stray light can also escape from the gap between the light-transmitting wall 121 and the light homogenizing member 130.

[0061] Stray light not only affects the visual effect, but also affects other parts of the robot. For example, some light-sensitive sensors on the robot are disturbed by stray light to send false signals, affecting the normal operation of the robot.

[0062] To solve the above problems, the light emitting assembly 100 of the present application further comprises a first light guide member and a second light guide member.

[0063] The first light guide member is arranged between the light emitting member 110 and the light-transmitting wall 121, and the light emitted by the light homogenizing member 130 passes through the first light guide member and then is emitted to the light-transmitting wall 121, and the first light guide member is used to limit the light from leaving the first scattering space P1.

[0064] It should be noted that limiting the light from leaving the first scattering space P1 means limiting the light from leaving the first scattering space P1 from the space outside the light-transmitting wall 121.

[0065] In some embodiments, the first light guide member reduces the formation of stray light by changing the material. For example, a material with high transmittance is used to increase the transmittance of the light and reduce the formation of stray light.

[0066] In some embodiments, the first light guide changes the transmission direction of the stray light emitted to the surroundings by changing the structure and absorbs the stray light to eliminate the stray light.

[0067] In some embodiments, the first light guide changes the transmission direction of the stray light emitted to the surroundings by changing the structure and absorbs the stray light to eliminate the stray light.

[0068] The second light guide is arranged between the light homogenizing member 130 and the light transmitting wall 121. The light emitted from the light transmitting wall 121 is emitted to the light homogenizing member 130 after passing through the second light guide. The second light guide is used to limit the light from leaving the second scattering space P2.

[0069] It should be noted that limiting the light from leaving the second scattering space P2 means limiting the light from leaving the second scattering space P2 from the space outside the light homogenizing member 130.

[0070] In some embodiments, the second light guide reduces the stray light by changing the material. For example, the second light guide is made of a material with high transmittance, so as to increase the transmittance of the light and reduce the stray light.

[0071] In some embodiments, the second light guide changes the transmission direction of the stray light emitted to the surroundings by changing the structure and absorbs the stray light to eliminate the stray light.

[0072] In some embodiments, the second light guide changes the transmission direction of the stray light emitted to the surroundings by changing the structure and absorbs the stray light to eliminate the stray light.

[0073] For example, in some embodiments, as shown in Figure 2 and Figure 4 The light diffusing member 120 further includes a first surrounding wall 122 and a second surrounding wall 123. Both the first surrounding wall 122 and the second surrounding wall 123 are non-light-transmitting structures.

[0074] In one embodiment, as shown in Figures 2 to 4 The mounting plate 112 and the light transmitting wall 121 are both annular. The first surrounding wall 122 encloses the inner edge and the outer edge of the light transmitting wall 121 and the light emitting member 110, so that the light emitted from the light emitting member 110 passes through the light transmitting wall 121 and is emitted. The light homogenizing member 130 is substantially annular. The second surrounding wall 123 encloses the inner edge and the outer edge of the light transmitting wall 121 and the light homogenizing member 130, so that the light passing through the light transmitting member is emitted through the light homogenizing member 130. The light homogenizing member 130 plays a guiding role for the light and eliminates the stray light.

[0075] It should be noted that the non-light-transmitting structure means that the light is scattered or reflected, and the light cannot be transmitted. Alternatively, the non-light-transmitting structure means that the light is absorbed.

[0076] When the non-light-transmitting structure is a structure that light cannot transmit through, in some embodiments, the non-light-transmitting structure is achieved by disposing a reflective layer or a refractive layer on the surface of the first surrounding wall 122 and the second surrounding wall 123, or the first surrounding wall 122 and the second surrounding wall 123 are made of a non-light-transmitting material.

[0077] When the non-light-transmitting structure is a structure that light is absorbed, in some embodiments, the non-light-transmitting structure is achieved by disposing a light-absorbing layer on the surface of the first surrounding wall 122 and the second surrounding wall 123. For example, black light-blocking paint is sprayed on the surface.

[0078] In some embodiments, the light-transmitting wall 121, the first surrounding wall 122, and the second surrounding wall 123 are integrally formed, improving the integrity of the light-emitting assembly 100.

[0079] In terms of structure, the first surrounding wall 122 is connected to the edge of the light-transmitting wall 121, and the first surrounding wall 122, the light-transmitting wall 121, and the light-emitting member 110 are connected to form a first scattering space P1, trapping light in the first scattering space P1 and leaving only the light-transmitting wall 121 as an exit, so that light is emitted from the light-transmitting wall 121, achieving the purpose of guiding light and reducing stray light.

[0080] The second surrounding wall 123 is connected to the edge of the light-transmitting wall 121, and the second surrounding wall 123, the light-transmitting wall 121, and the light-uniformizing member 130 are connected to form a second scattering space P2, trapping light in the second scattering space P2 and leaving only the light-uniformizing member 130 as an exit, so that light is emitted from the light-uniformizing member 130, achieving the purpose of guiding light and reducing stray light.

[0081] In related technologies, the light beam emitted by the light source is directly emitted to the light-emitting wall, which is equivalent to the light emitted by the light source propagating through the air between the light source and the light-emitting wall, and only one scattering is performed, so the scattering efficiency is low. Therefore, the distance between the light source and the light-emitting wall satisfies a large irradiation distance, so that the light emitted from the light-emitting wall is uniform, resulting in a relatively large volume of the light-emitting assembly.

[0082] To solve the above problems, in some embodiments, as shown in FIG. 1, the distance between the light-emitting member 110 and the light-uniformizing member 130 is L, and L satisfies 6mm≤L≤10mm. Figure 4 By reserving this distance, the light emitted by the light-emitting member 110 is preliminarily scattered, so that the light emitted by the light-emitting member 110 can be emitted from more angles into the light-scattering member 120, improving the light-scattering efficiency. By disposing the light-scattering member 120, the light-scattering efficiency is improved, so that the light emitted from the light-uniformizing member 130 is uniform and soft. At the same time, the required light-scattering distance between the light-emitting member 110 and the light-uniformizing member 130 is shortened, reducing the volume of the light-emitting assembly 100.

[0083] The distance between the light emitting member and the light transmitting wall 121 is L, which is not limited to the examples and is 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc.

[0084] As described above, the light emitted by the light emitting member 110 is from the plurality of LED lamps 111, which are point light sources, and the emitted light has the characteristic of high concentration.

[0085] In some embodiments, by arranging the light transmitting wall 121 close to the side of the light emitting member 110 to collimate the light emitted by the light emitting member 110, the concentrated light from the LED lamps 111 is scattered into parallel light, and the angle range of the light entering the light transmitting member is expanded.

[0086] In some embodiments, the side of the light transmitting wall 121 close to the light emitting member 110 is a concave surface, and the concave surface forms a first light scattering structure 1211.

[0087] It should be noted that the concave surface covers most of the light emitting surface of the LED lamp 111. As shown in Figure 4 The light emitting range of the LED lamp 111 is a hemisphere centered on the lamp bead, and the concave surface covers at least 50% of the surface of the hemisphere, thereby improving the collimation efficiency of the concave surface and improving the scattering ability of the light scattering member 120.

[0088] In some embodiments, the side of the light transmitting wall 121 close to the light emitting member 110 is a concave surface, and the concave surface forms a first light scattering structure 1211.

[0089] For example, the scattering angle of the light can be increased by arranging a polyhedral structure, a grating structure, a microlens array, etc.

[0090] In some embodiments, the side of the light transmitting wall 121 close to the light emitting member 110 is a concave surface, and the concave surface forms a first light scattering structure 1211.

[0091] In some embodiments, as shown in Figure 2 The convex lens 12121 is in the shape of a polyhedron, such as a trihedron, a tetrahedron, a pentahedron, a hexahedron, or a hemisphere, etc. When the convex lens is in the shape of a tetrahedron, the angle of the tetrahedron is 30-60°.

[0092] In some embodiments, as shown in Figure 4 The side of the light transmitting wall 121 close to the light emitting member 110 is a concave surface, and the concave surface forms a first light scattering structure 1211.

[0093] The light emitting member 110 includes a light transmitting main body and a light scattering structure.

[0094] In some embodiments, the light-uniformizing structure is a light-uniformizing substance mixed in a light-transmitting body. For example, the light-transmitting body is made of PC or acrylic material, and the light-uniformizing substance is light-uniformizing powder.

[0095] In some embodiments, the light-uniformizing structure is a light-uniformizing substance coating, which is arranged on the surface of the light-transmitting body.

[0096] As shown in Figure 5 and Figure 6 , the present application also provides a light-emitting device 1000, which comprises the light-emitting assembly 100 and the base 200 in any of the above embodiments. The light-emitting assembly 100 is mounted on the base 200, and the base 200 is connected to the side of the light-uniformizing member 130 away from the light-emitting member 110.

[0097] As mentioned above, the light-emitting assembly 100 can be mounted on the head and the trunk of a robot, and the shape and material of the base 200 are designed and changed according to the mounting position of the light-emitting assembly 100.

[0098] Through the cooperation of the light-uniformizing member 130 and the base 200, the light-uniformizing member 130 can change the light-emitting position, so as to change the display pattern of the light-emitting assembly 100.

[0099] In one embodiment, referring to Figure 5 and Figure 6 , the light-uniformizing member 130 is annular, and the base 200 covers the middle part of the light-uniformizing member 130, so that the display pattern of the light-emitting assembly 100 is circular.
