Technical field

[0001] The present utility model relates to the technical field of light-emitting buttons, in particular a light-emitting button. State of the art

[0002] To make it easier for the user to identify a button or knob at night, the button or knob is usually equipped with illumination. For example, the present utility model with publication number CN 220543791U discloses a light-emitting button comprising a button body, wherein the button body includes a translucent cover and a button housing, the translucent cover being provided at an upper end of the button housing and a light-emitting assembly being provided inside the button housing.The light-emitting assembly comprises a reflector, a light guide, and an LED light source located below the light guide. The light guide has a translucent surface, and a translucent groove is provided between the button housing and the reflector. The translucent surface extends into the translucent groove, and the reflector is provided with a reflective layer to reflect the light emitted from the translucent surface back to the translucent cover. However, existing light-emitting buttons generally have some problems: In brightly lit environments, the button's light effect appears unidirectional due to the uniform brightness distribution, resulting in low visibility, and the button's position is not easily and quickly determined by the user.Similarly, in dimly lit environments, a single brightness level can sometimes be too dazzling, while at night, the illuminated areas of the buttons lack sufficient contrast against the background, increasing the risk of accidental presses. Therefore, the question of how to develop a light-emitting button that effectively improves detection, reduces false presses, and ensures good visibility in various lighting conditions has become a pressing issue in the field. Disclosure of the registration

[0003] The purpose of the present utility model is to develop a light-emitting button to solve the above technical problems, which improves the recognition of the button by the user under different lighting environments and reduces the risk of accidental contact.

[0004] To solve the above technical problems, the present utility model uses the following technical solution: a light-emitting button comprising the following: a housing, wherein an upper and a lower end of the housing are each provided with openings; a translucent cover, wherein the translucent cover is inserted into the opening at the top of the housing; an inner lining, wherein the inner lining is inserted into the lower opening of the housing, and wherein the inner lining is detachably connected to the translucent cover to form a circular mounting cavity, the mounting cavity being provided with an annular support structure, the support structure being made of translucent material; and a light-emitting assembly provided in the mounting cavity, wherein the light-emitting assembly comprises a light-shielding ring, a mirror plate, a single reflector plate and an annular lamp body, wherein the light-shielding ring covers the edge region of the mirror plate, wherein the mirror plate and the single reflector plate are located at both ends of the support structure, wherein the lamp body surrounds an outer wall of the support structure, and wherein a light-emitting side of the lamp body faces the support structure.

[0005] Preferably, a connecting ring is provided on an upper end face of the inner lining, wherein a mounting ring is provided on a lower end face of the translucent cover, wherein the mounting ring is placed on the connecting ring, wherein the mounting ring comprises at least two snap elements, wherein the connecting ring is provided with snap grooves so that the snap elements snap into each other, so that the mounting cavity is formed by the upper end face of the inner lining, the inner wall of the connecting ring and the inner wall of the translucent cover fitting together.

[0006] Preferably, the connecting ring is provided coaxially and spaced apart from the support structure, wherein the mirror plate is inserted into the connecting ring, wherein the lower end surface of the mirror plate and the upper end surface of the support structure are in contact with each other, wherein the inner wall of the connecting ring, the outer wall of the support structure, the lower end surface of the mirror plate and the upper end surface of the inner lining interact to form an emission cavity for receiving the lamp body.

[0007] Preferably, the upper end surface of the connecting ring is provided with an annular limiting groove, wherein the upper end surface of the mirror plate and the inner wall of the limiting groove interact with each other and the light-shielding ring is inserted into the limiting groove.

[0008] Preferably, the support structure comprises a first support ring and a second support ring, which are arranged coaxially, wherein the first support ring is firmly connected to the upper end surface of the inner lining, wherein the single reflector plate and the second support ring are successively inserted into the first support ring, with the opposite sides of the mirror plate and single reflector plate each bearing against the two end surfaces of the second support ring.

[0009] Preferably, the lamp body comprises an annular light strip and a number of light source bodies spaced apart on the light strip.

[0010] Preferably, the inner wall of the housing is provided with at least one positioning strip, wherein the positioning strip extends along the vertical direction of the housing, and wherein a positioning groove for inserting the positioning strip is provided on the upper end face of the inner lining.

[0012] Compared to the prior art, the present utility model has the following advantageous effects: When the light-emitting button is in operation, the light emitted from the lamp body shines onto the support structure, and the light passes through the support structure into the space between the mirror plate and the single reflector plate. In this space, the light is reflected and refracted many times by the mirror plate and the single reflector plate and then emitted outwards through the translucent cover. The light-shielding ring is able to effectively block unwanted rays at the edges of the mirror plate and reduce the disturbance caused by stray light.The design of the ring-shaped lamp body ensures that the light emitted from the lamp body through the supporting structure is reflected and refracted into the space between the mirror plate and the single reflector plate. This creates a ring-shaped layer of overlapping shadows and a spatial expansion of the lighting effect on the translucent cover. As a result, the light-emitting buttons produce lighting effects with a greater sense of three-dimensionality, hierarchy, and ornamentation. This improves user identification of the buttons in various lighting environments and reduces the risk of accidental presses. Furthermore, the inner lining and the translucent cover are removable, making it easy for the user to repair and replace parts of the light-emitting assembly as needed.

Specific embodiments

[0014] The present utility model is described in more detail below with reference to exemplary embodiments in conjunction with the accompanying drawings.

[0015] As in the Fig. 1, Fig. 2 and Fig.As shown in Figure 3, a light-emitting button comprises a housing 1, a translucent cover 2, an inner lining 3, and a light-emitting assembly 6, and the housing 1 has an annular structure. The upper and lower ends of the housing 1 are each provided with openings, four outwardly convex positioning strips 101 are provided on the inner wall of the housing 1, extending along the vertical direction of the housing 1, and a positioning groove 304 is located on the upper end face of the inner lining 3, into which the positioning strips 101 can be inserted.The positioning strips 101 and the positioning grooves 304 are used to guide the inner lining 3 so that it is inserted into the housing 1 in the correct position, so that the inner lining 3 can only be moved in the inner wall of the housing 1, and to prevent the inner lining 3 from rotating in the housing 1 due to external forces.

[0016] The translucent cover 2 is inserted into the opening at the top of the housing 1, and the inner wall of the housing 1 and the outer wall of the translucent cover 2 form a butt fit or a gap fit between them, and a connecting ring 301 is fixedly connected to the upper end face of the inner lining 3, and a mounting ring 201 is provided on the lower end face of the translucent cover 2. The mounting ring 201 is placed on the connecting ring 301, the mounting ring 201 includes two symmetrically arranged snap elements 202, and the outer wall of the connecting ring 301 is provided with a snap groove 302 so that the snap elements 202 snap into one another to create a detachable connection between the inner lining 3 and the translucent cover 2.The upper end surface of the inner lining 3, the inner wall of the connecting ring 301 and the inner wall of the translucent cover 2 fit together, forming a circular mounting cavity 4.

[0017] The mounting cavity 4 is provided with an annular support structure 5 made of a translucent material, which can be a transparent plastic or an acrylic material. The support structure 5 comprises a first support ring 51 and a second support ring 52, which are arranged coaxially, wherein the first support ring 51 is fixedly connected to the upper end face of the inner lining 3 and the second support ring 52 is a separate component. The connecting ring 301 is arranged coaxially and spaced apart from the first support ring 51 of the support structure 5.

[0018] The light-emitting assembly 6 is located in the mounting cavity 4, and the light-emitting assembly 6 comprises a light-shielding ring 61, a mirror plate 62, a single reflector plate 64 and an annular lamp body 63, wherein the single reflector plate 64 and the first support ring 51 are successively inserted into the first support ring 51, the mirror plate 62 is inserted into the connecting ring 301 and the lower end surface of the mirror plate 62 and the upper end surface of the first support ring 51 of the support structure 5 abut each other, wherein the opposite sides of the mirror plate 62 and single reflector plate 64 each abut the two end surfaces of the second support ring 52, so that the mirror plate 62 and the single reflector plate 64 can be arranged parallel and spaced apart from each other with the support provided by the support structure 5.The inner wall of the connecting ring 301, the outer wall of the first support ring 51 of the support structure 5, the lower end face of the mirror plate 62, and the upper end face of the inner lining 3 interact to form an emission cavity 7 for receiving the lamp body 63. The lamp body 63 comprises an annular light strip 631 and a number of light source bodies 632 spaced apart on the light strip 631, wherein the light source bodies 632 can be LED lamps. The lamp body 63 surrounds the outer wall of the support structure 5, and the light-emitting side of the lamp body 63 faces the support structure 5.

[0019] The upper end surface of the connecting ring 301 is provided with an annular limiting groove 303, the upper end surface of the mirror plate 62 and the inner wall of the limiting groove 303 cooperate, and the light-shielding ring 61 is inserted into the limiting groove 303, and when the translucent cover 2 is assembled with the inner lining 3, the inner wall of the translucent cover 2 cooperates with the limiting groove 303 to limit the light-shielding ring 61 and to ensure that the light-shielding ring 61 covers the edge region of the mirror plate 62.

[0020] Both the single reflector plate 64 and the mirror plate 62 are made of a translucent material, which can be a transparent plastic or an acrylic material. A single reflector plate 64 is applied to the single reflector plate 64, and a second optical coating 602 is applied to the upper and lower end faces of the mirror plate 62. The first optical coating 601 is a reflective film and reflects only light. The second optical coating 602 is a translucent metal film layer, and the material of the translucent metal film layer can be silver, aluminum, or nickel. The second optical coating 602 reflects and refracts light passing through the mirror plate 62.

[0021] When the light-emitting button is in operation, the light passes through the support structure 5 to be refracted in the space between the mirror plate 62 and the single reflector plate 64. The light entering the space is reflected multiple times by the mirror plate 62 and the single reflector plate 64, while within the space it is refracted successively by the mirror plate 62 and the translucent cover 2 to shine outwards. The light-shielding ring 61 is able to effectively block the unwanted rays at the edges of the mirror plate 62 and reduce the interference from stray light.The design of the ring-shaped lamp body 63 ensures that the light emitted from the lamp body 63 through the support structure 5 into the space between the mirror plate 62 and the single reflector plate 64 is reflected and refracted. This creates a ring-shaped layer of overlapping shadows and a spatial extension of the lighting effect on the translucent cover 2. As a result, the light-emitting buttons produce lighting effects with a better sense of three-dimensionality, hierarchy, and ornamentation. This improves user recognition of the buttons in various lighting environments and reduces the risk of accidental presses. Furthermore, the inner lining 3 and the translucent cover 2 are removable, making it easier for the user to repair and replace parts of the light-emitting assembly 6 as needed.
