[0042] Light-emitting components are widely used in robots. For example, light-emitting components can be applied to the head of the robot, set in the ears, eyes or mouth, etc., and interact with the user and indicate information by changing the color of the light emitted by the light-emitting components; light-emitting components can also be applied to the torso of the robot to display robot status data indication, etc.
[0043] In the related art, the light beam emitted by the light source in the robot light emitting device is directly directed toward the light emitting wall. Such a light emitting design easily causes the problem of uneven light emitting.
[0044] In order to solve the above technical problems, Figure 1 and Figure 2 As shown, an embodiment of the present application provides a light emitting assembly 100 , which is mainly used in a robot. The light emitting assembly 100 includes a light emitting element 110 , a light diffusing element 120 and a light homogenizing element 130 .
[0045] The light emitting element 110 has a light emitting side 113. The light emitted by the light emitting element 110 is emitted after passing through the light diffuser 120 and the light homogenizer 130. The light emitted by the light emitting element 110 has a concentrated illumination angle. After passing through the light diffuser 120 and the light homogenizer 130, the light is dispersed into soft parallel diffuse reflection light with multiple illumination angles and a wide illumination range.
[0046] refer to Figure 2 The light emitting element 110 includes a mounting plate 112, on which a plurality of LED lamps 111 are disposed. 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, Figure 2 As shown, the LED lamp 111 is disposed on one side of the mounting plate 112 to form a light emitting side 113 of the light emitting element 110 .
[0048] In some embodiments, the LED lamps 111 are disposed on opposite sides of the mounting plate 112 to form two light emitting sides 113 of the light emitting element 110 , and a light diffuser 120 and a light homogenizer 130 are correspondingly disposed on the light emitting side 113 of the LED lamp 111 on each side.
[0049] In some embodiments, the mounting plate 112 is connected to an external control chip to control the color change of multiple LED lights 111 or coordinate the brightness of each LED light 111, and display the information of the robot by changing the color and brightness of the LED light 111, such as blue represents the working status, green represents the charging status, red represents the warning status, etc.
[0050] The shape of the mounting plate 112 can be changed according to the actual application part of the robot with the light emitting assembly 100. For example, taking the light emitting assembly 100 applied to the ear part of the robot as an example, the edge contour of the mounting plate 112 is close to the shape of the ear.
[0051] Accordingly, the light emitted by the light emitting element 110 passes through the light homogenizing element 130 and then is emitted. The light homogenizing element 130 has a light emitting wall for transmitting the light to the outside. The shape of the light emitting wall can also be changed accordingly according to the actual application part of the robot of the light emitting component 100. For example, taking the light emitting component 100 applied to the ear or eye of the robot as an example, the edge contour of the light emitting wall is close to the shape of the ear or eye, so that the light emitting component 100 can simulate the human ear or eye.
[0052] Of course, in some embodiments, the light emitting assembly 100 may not simulate the shape of human organs. For example, if the light emitting assembly 100 is also arranged at the ear of the robot, the light emitting assembly 100 may be arranged in a spherical shape.
[0053] In some embodiments, Figures 2 to 4 As shown, the light homogenizer 130 is connected to the light emitting element 110 and defines an installation space between the light emitting element 110. The light diffuser 120 is disposed on the light emitting side 113 of the light emitting element 110 and is located between the light emitting element 110 and the light homogenizer 130 and is installed in the installation space.
[0054] It is understood that when light propagates in a medium, scattering occurs. Generally, in the air, the scattering intensity of light is relatively weak, while in solids, the scattering intensity is usually stronger because photons interact more frequently with matter.
[0055] like Figures 2 to 4 As shown, the light diffuser 120 and the light emitting element 110 form a first scattering space P1, the light diffuser 120 and the light homogenizer 130 form a second scattering space P2, the light diffuser 120 has a first light diffuser structure 1211 on the side close to the light emitting element 110, and the light diffuser 120 has a second light diffuser structure 1212 on the side close to the light homogenizer 130. The light emitted by the light emitting element 110 passes through the first scattering space P1, the light diffuser 120, the second scattering space P2 and the light homogenizer 130 in sequence and is emitted.
[0056] The light emitted by the light emitting element 110 first passes through the first scattering space P1, the light propagates in the air and the first scattering occurs; then passes through the light diffusing element 120, the light propagates in the solid and the second scattering occurs; then passes through the second scattering space P2, the light propagates in the air again and the third scattering occurs; finally passes through the light homogenizing element 130, the light propagates in the solid and the fourth scattering occurs, thereby improving the scattering efficiency of the light and making the light emitted from the light homogenizing element 130 uniform and soft.
[0057] At the same time, the diffuser 120 of the present application also has a first diffuser structure 1211 and a second diffuser structure 1212. The first diffuser structure 1211 and the second diffuser structure 1212 can improve the diffuser ability of the diffuser 120, improve the diffuser efficiency, and make the light emitted from the light homogenizing element 130 uniform and soft.
[0058] In some embodiments, reference Figure 4 The light diffuser 120 includes a light-transmitting wall 121 , and the light-transmitting wall 121 is spaced apart from the light-emitting element 110 and the light-dispersing element 130 .
[0059] It can be understood that the scattering angle of light is random.
[0060] When light passes through the gap between the light-transmitting wall 121 and the light-emitting element 110, the distance between the light-transmitting wall 121 and the light-emitting element 110 is short, and most of the light can enter the light-transmitting wall 121, and a small part of the light is scattered around to form stray light. Similarly, stray light will also escape from the gap between the light-transmitting wall 121 and the light-distributing element 130.
[0061] Stray light not only affects the visual effect, but also affects other parts of the robot. For example, some photosensitive sensors on the robot will be disturbed by stray light, causing the photosensitive sensors to send out erroneous signals, thus affecting the normal operation of the robot.
[0062] In order to solve the above problems, the light emitting assembly 100 of the present application further includes a first light guide and a second light guide.
[0063] The first light guide is disposed between the light emitting element 110 and the light-transmitting wall 121 . The light emitted by the light homogenizing element 130 passes through the first light guide and then projects toward the light-transmitting wall 121 . The first light guide 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 stray light generation by changing the material, for example, by using a material with high transmittance to increase the transmittance of light and reduce stray light generation.
[0066] In some embodiments, the first light guide changes its structure to change the transmission direction of the stray light emitted to the surroundings through refraction or reflection, and transmits the stray light in a concentrated manner toward the light-transmitting wall 121 .
[0067] In some embodiments, the first light guide member absorbs stray light emitted to the surroundings by changing its structure and material, thereby achieving the purpose of eliminating stray light.
[0068] The second light guide is disposed between the light homogenizer 130 and the light-transmitting wall 121 . The light emitted from the light-transmitting wall 121 passes through the second light guide and then is emitted toward the light homogenizer 130 . 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 refers to limiting the light from leaving the second scattering space P2 from the space outside the light homogenizer 130 .
[0070] In some embodiments, the second light guide member reduces stray light generation by changing the material, for example, by using a material with high transmittance to increase the transmittance of light and reduce stray light generation.
[0071] In some embodiments, the second light guide changes its structure to refract or reflect stray light emitted in all directions, thereby changing the transmission direction of the light and concentrating the light in the direction of the light-transmitting wall 121 .
[0072] In some embodiments, the second light guide member absorbs stray light emitted to the surroundings by changing its structure and material, thereby achieving the purpose of eliminating stray light.
[0073] For example, in some embodiments, Figure 2 and Figure 4 As shown, the light diffuser 120 further includes a first surrounding wall 122 and a second surrounding wall 123 , and both the first surrounding wall 122 and the second surrounding wall 123 are non-light-transmitting structures.
[0074] In one embodiment, if Figures 2 to 4 As shown, the mounting plate 112 and the light-transmitting wall 121 are both annular, and the first surrounding wall 122 closes the inner and outer edges of the light-transmitting wall 121 and the light-emitting member 110, so that the light emitted from the light-emitting member 110 is all emitted through the light-transmitting wall 121, which guides the light and achieves the purpose of eliminating stray light. The light-distributing member 130 is roughly annular, and the second surrounding wall 123 closes the inner and outer edges of the light-transmitting wall 121 and the light-distributing member 130, so that the light passing through the light-transmitting member is all emitted through the light-distributing member 130, which guides the light and achieves the purpose of eliminating stray light.
[0075] It should be noted that a non-light-transmitting structure refers to a structure where light is scattered or reflected and cannot be transmitted. Alternatively, a non-light-transmitting structure refers to a structure where light is absorbed.
[0076] When the non-light-transmitting structure is a structure that light cannot pass through, in some embodiments, it is achieved by providing a reflective layer or a refractive layer on the surfaces 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 non-light-transmitting material.
[0077] When the non-light-transmitting structure is a structure that absorbs light, in some embodiments, it is achieved by providing a light-absorbing layer on the surfaces of the first surrounding wall 122 and the second surrounding wall 123. For example, black light-shielding 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 to improve the integrity of the light-emitting component 100 .
[0079] Structurally, 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 element 110 are connected to form a first scattering space P1, which traps the light in the first scattering space P1 and leaves only one exit, the light-transmitting wall 121, so that all the light is emitted from the light-transmitting wall 121, thereby achieving the purpose of guiding the 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 homogenizer 130 are connected to form a second scattering space P2, which traps the light in the second scattering space P2 and leaves only one exit, the light homogenizer 130, so that all the light is emitted from the light homogenizer 130, thereby achieving the purpose of guiding the light and reducing stray light.
[0081] In the related art, the light beam emitted by the light source is directly directed toward the light output wall, which is equivalent to the light emitted by the light source being propagated through the air between the light source and the light output wall, and is scattered only once, resulting in low scattering efficiency. Therefore, the distance between the light source and the light output wall meets a larger irradiation distance to make the light emitted from the light output wall uniform, resulting in a larger volume of the light-emitting component.
[0082] In view of the above problems, in some embodiments, Figure 4 As shown, in the transmission direction of the light emitted by the light emitting element 110, the distance between the light emitting element and the light-transmitting wall 121 is L, which satisfies: 6mm≤L≤10mm. By reserving this distance, the light emitted by the light emitting element 110 is initially scattered, so that the light emitted by the light emitting element 110 can enter the light diffuser 120 from more angles, thereby improving the light diffusion efficiency. By setting the light diffuser 120, the light diffusion efficiency is improved, so that the light emitted from the light homogenizing element 130 is uniform and soft. At the same time, the required light diffusion distance between the light emitting element 110 and the light homogenizing element 130 is shortened, thereby reducing the volume of the light emitting component 100.
[0083] The distance L between the light emitting member and the light transmitting wall 121 is 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc., which is not limited to the examples.
[0084] As mentioned above, the light emitted by the light emitting element 110 comes from a plurality of LED lamps 111 . The LED lamps 111 are point light sources, and the light emitted has the characteristic of high concentration.
[0085] In some embodiments, a light-transmitting wall 121 is disposed on one side close to the light-emitting element 110 to collimate the light emitted by the light-emitting element 110 , scattering the concentrated light from the LED lamp 111 into parallel light, thereby expanding the angle range of the light entering the light-transmitting element.
[0086] In some embodiments, a side of the light-transmitting wall 121 close to the light-emitting element 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. Figure 4 As shown, 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 increasing the collimation efficiency of the concave surface and improving the scattering ability of the diffuser 120 .
[0088] In some embodiments, the side of the light-transmitting wall 121 close to the light-diffusing element 130 is used to increase the irradiation angle of the light passing through the light-diffusing element 120 , so that the isotropic scattering of the light is more uniform.
[0089] Exemplarily, the scattering angle of light can be increased by providing a polyhedron structure, a grating structure, a microlens array, etc.
[0090] In some embodiments, a plurality of convex lenses 12121 are formed on one side of the light-transmitting wall 121 close to the light homogenizing element 130 , and the plurality of convex lenses 12121 are evenly distributed on the surface of the light-transmitting wall 121 to form a second light-scattering structure.
[0091] In some embodiments, Figure 2 As shown, 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, Figure 4 As shown, a concave surface is formed on one side of the light homogenizer 130 close to the light diffuser 120 , which scatters the light passing through the second scattering space P2 into parallel light, thereby expanding the angle range of the light entering the light homogenizer 130 .
[0093] The light homogenizer 130 includes a light-transmitting body and a light homogenizing structure.
[0094] In some embodiments, the light-homogenizing structure is a light-homogenizing substance mixed in the light-transmitting body. For example, the light-transmitting body is made of PC or acrylic material, and the light-homogenizing substance is light-homogenizing powder.
[0095] In some embodiments, the light-homogenizing structure is a light-homogenizing material coating, and the light-homogenizing material coating is disposed on the surface of the light-transmitting body.
[0096] like Figure 5 and Figure 6 As shown, an embodiment of the present application further provides a light-emitting device 1000, comprising the light-emitting component 100 and the substrate 200 in any of the above embodiments, the light-emitting component 100 is installed on the substrate 200, and the substrate 200 is connected to the side of the light-distributing member 130 away from the light-emitting member 110.
[0097] As mentioned above, the light emitting component 100 can be installed at the head and torso of the robot, and the shape and material of the base 200 are designed and changed according to the installation position of the light emitting component 100 .
[0098] By the matching connection between the light homogenizer 130 and the base 200 , the light emitting position of the light homogenizer 130 can be changed, thereby changing the display pattern of the light emitting component 100 .
[0099] In one embodiment, reference Figure 5 and Figure 6 The light homogenizer 130 is annular, and the base 200 covers the middle of the light homogenizer 130, so that the display pattern of the light emitting component 100 is circular.
