[0034] Lighting effects refer to the creation of specific visual experiences and atmospheres through different lighting technologies and design techniques. For example, the abyss lighting effect is based on planar reflection, which produces an infinitely superimposed mirror effect through the mutual reflection between multiple layers of reflectors or semi-reflectors. In audio products, it is necessary to consider the vibration problem that may occur when the machine plays music. The full reflection plate and the semi-reflector are bonded together with optical adhesive, which will increase the cost and reduce the yield rate during the production of the reflector, thus affecting the abyss lighting effect.
[0035] This invention proposes a light-emitting component and its manufacturing method, as well as an electronic product and its assembly method.
[0036] Please see Figure 1 In one embodiment of the present invention, the light-emitting component 1 includes:
[0037] The light source structure 100 has a light-emitting point;
[0038] The light-emitting element 110 is disposed on the light-emitting side of the light source structure 100; and
[0039] The reflector 120 has a first surface facing the light source structure 100 and a second surface facing the light-emitting element 110. The first surface is provided with a total reflection coating 121 and the second surface is provided with a semi-reflective coating 122. The total reflection coating 121 has a light-transmitting hole corresponding to the light-emitting point for light to pass through.
[0040] In the technical solution of this invention, the light-emitting component 1 includes a light source structure 100, a reflector 120, and a light-emitting component 110 arranged sequentially. The two opposite sides of the reflector 120 are a first surface and a second surface, respectively. A total reflection coating 121 is disposed on the first surface, and a semi-reflective coating 122 is disposed on the second surface. The total reflection coating faces the light source structure 100, and the semi-reflective coating 122 faces the light-emitting component 110. Light is emitted from the light-emitting point. The light passes through a light-transmitting hole, through the reflector 120 body, and reaches the second surface. Part of the light passes through the semi-reflective coating 122 and is refracted onto the light-emitting component 110, displaying the light effect. The remaining part of the light is reflected by the semi-reflective coating 122 back to the first surface, and then passes through the total reflection coating... The light reflected from layer 121 to the second surface is still divided into two parts. One part is refracted through the semi-reflective coating 122 to the light-emitting element 110, and the other part is reflected back to the first surface. This cycle repeats, allowing the light to undergo multiple reflections, resulting in light of different brightness passing through the light-emitting element 110 and creating a superimposed lighting effect. The better the reflection effect between the semi-reflective coating 122 and the total reflection coating 121, the more times the light is reflected between the total reflection coating 121 and the semi-reflective coating 122, resulting in a better visual effect. Since the reflector 120 itself can achieve total reflection, semi-reflection, and light transmission, it reduces production costs, ensures environmental cleanliness, and further guarantees the lighting effect of the abyss lighting effect.
[0041] In a specific embodiment, the reflector 120 is a light-transmitting material, with a total reflection coating 121 and a semi-reflective coating 122 respectively provided on its first and second surfaces, so that light can not only pass through its interior, but also be reflected multiple times to achieve the effect of abyss lighting. In addition, the light transmittance of the total reflection coating 121 is 0%, and the light transmittance of the semi-reflective coating 122 is 8%-15%, preferably 12%.
[0042] In this process, the light emitted from the light source structure 100 first enters the reflector 120 through the light-transmitting hole and reaches the semi-reflective coating 122. The semi-reflective coating 122 projects part of the light and reaches the light-emitting element 110, allowing the observer to see a brighter light effect. When the light is reflected at the semi-reflective coating 122 to the total reflection coating 121, and then reflected back to the semi-reflective coating 122, the light undergoes a second transmission at the semi-reflective coating 122 and reaches the light-emitting element 110. The observer sees a slightly weaker light effect. The two light effects are identical except for brightness and distance. After multiple cycles, the observer sees multiple light effects with the same shape but different distances and brightness, thus forming the abyss light effect.
[0043] In embodiments of the present invention, both the total reflection coating 121 and the semi-reflective coating 122 are formed by vacuum plating. The coatings are formed on the first surface and the second surface by vacuum plating, so that the total reflection coating 121 with 0% light transmittance is formed on the first surface and the semi-reflective coating 122 is formed on the second surface. For example, to achieve high reflectivity on the first surface, a metal coating, including but not limited to silver, aluminum or copper, can be selected. On the second surface, since light is required to both pass through and reflect, a material with a certain light transmittance, such as silicon oxide or magnesium oxide, can be selected.
[0044] In addition, after the vacuum coating is applied to the first surface, the total reflection coating 121 needs to be protected. For example, a PE protective film can be applied to the surface of the vacuum coating to protect the coating and prevent scratches from affecting the reflection of light.
[0045] In an embodiment of the present invention, the light-transmitting hole is formed by an engraving process, specifically a laser engraving process. A portion of the total reflection coating 121 is removed by laser to form the light-transmitting hole, which allows light to pass through the reflector 120. Laser engraving is fast and efficient. In addition, the laser engraving process does not contact the vacuum coating, thus avoiding wear on the total reflection coating 121.
[0046] In an embodiment of the present invention, the reflector 120 is configured as an acrylic sheet. The acrylic sheet has high transparency and a light transmittance of up to 95%, meaning that light can pass through the reflector 120 and achieve multiple reflections between the total reflection coating 121 and the semi-reflection coating 122. In addition, the acrylic sheet is lighter and less prone to breakage, which not only makes it easier to transport the light-emitting component 1, but also ensures higher safety.
[0047] In another embodiment, the light-emitting element 110 is configured as glass with high light transmittance. The light is reflected once or multiple times in the reflector 120, passes through the semi-reflective coating 122, enters the glass, and is transmitted through the glass to be presented to the observer. Different shapes of glass can be made by calendering to present different abyss lighting effects.
[0048] Please see Figure 3 In an embodiment of the present invention, the light source structure 100 includes a lamp board 101 and lamp beads 102 disposed on the lamp board 101. The lamp beads 102 form light-emitting points. The lamp board 101 can be a PCB board or a circuit board. The lamp beads 102 are mounted on the lamp board 101 to provide power to the lamp beads 102. The light generated by the lamp beads 102 enters the reflector 120 through the light-transmitting hole, so as to form a deep abyss lighting effect by multiple reflections in the reflector 120. The lamp beads 102 can be LED lamp beads 102. Different colored lamp beads 101 can be selected according to actual needs, that is, different wavelengths are emitted.
[0049] In an embodiment of the present invention, multiple LED beads 102 are arranged in an array along the length of the lamp plate 101 so that the light emitted by each LED bead 102 can enter the reflector 120 through the light-transmitting hole and be reflected multiple times on the first and second surfaces of the reflector 120. In addition, if you want to adjust the lighting effect, such as changing the shape, you can also adjust it by adjusting the relative position of the LED beads 102.
[0050] Please see Figure 1 and Figure 3 In an embodiment of the present invention, the light-emitting component 1 further includes a light guide plate 130, which is disposed between the light source structure 100 and the reflector 120. The light emitted by the light source structure 100 enters the light guide plate 130 and propagates towards the reflector 120 through total internal reflection. By changing the direction of the light, the light is evenly dispersed on the light guide plate 130 to form a planar light source, which is more conducive to the presentation of the abyss lighting effect.
[0051] This invention also proposes a method for manufacturing the light-emitting component 1, please refer to... Figure 4 The light-emitting component 1 is the light-emitting component 1 of any of the above embodiments, and the manufacturing method includes:
[0052] S1. Apply a total reflection coating 121 to the first surface of the reflector 120;
[0053] S2. Cover the total reflection coating 121 with a protective film;
[0054] S3. A semi-reflective coating 122 is deposited on the second surface of the reflector 120;
[0055] S4. Remove the total reflection coating 121 on the area corresponding to the light-emitting point on the reflector 120 to form a light-transmitting hole.
[0056] Please see Figure 2 and Figure 3 The present invention also proposes an electronic product comprising a product body, a metal mesh 2, and a light-emitting component 1. The light-emitting component 1 has the structure of the light-emitting component 1 in the above embodiments. Since this electronic product adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The metal mesh 2 and the light-emitting component 1 are both adhered to the product body. Specifically, the light-emitting element 110 is adhered to the product body, and the edge of the light-emitting element 110 is easily attached and adhered to the metal mesh 2.
[0057] This electronic product includes, but is not limited to, portable speakers, electric toothbrushes, rechargeable desk lamps, and electronic photo frames, among other upright charging products.
[0058] Please refer to Figure 5 The present invention also proposes an assembly method for electronic products, comprising:
[0059] A1. Attach the light-emitting component 1 to the main body of the product;
[0060] A2. Adhere the metal mesh 2 to the main body of the product. During the process of adhering the metal mesh 2, push the metal mesh 2 toward the light-emitting component 1 so that the edge of the metal mesh 2 is adhered to the edge of the light-emitting component 110.
[0061] Specifically, one edge of the light-emitting element 110 is curved, and one side of the metal mesh 2 is also curved, with the curve of the metal mesh 2 matching that of the light-emitting element 110. Because the light-emitting element 110 is prone to deformation during tempering, the contour of its curved edge cannot be well controlled. If the metal mesh 2 is installed in the product body first, and then the light-emitting component 1 is installed, the deformation of the light-emitting element 110 makes it difficult to control the gap between it and the metal mesh 2. A large gap affects product quality, and the contour requirements for the light-emitting element 110 are high during installation, requiring a secondary edge grinding process, which is costly. However, compared to the light-emitting element 110, the metal mesh 2 can undergo slight deformation. This option involves first installing the light-emitting component 1 onto the product body. A specific tooling fixture clamps the light-emitting component 110 and adheres it to the product body using adhesive. The fixture's suction nozzle then picks up the metal mesh 2 and places it toward the product body. While waiting for a 1mm gap between the metal mesh 2 and the product body, a cylinder is used to push the metal mesh 2 toward the light-emitting component 110. The slight deformation of the metal mesh 2 facilitates a tight fit between the metal mesh 2 and the edge of the light-emitting component 110. The metal mesh 2 is bonded to the product body with AB glue, and the edge is bonded to the light-emitting component 110 with foam adhesive, which helps to close the gap between the metal mesh 2 and the light-emitting component 110. The metal mesh 2 can be, but is not limited to, aluminum mesh.

Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
