Description

Technical Field

[0001] The utility model relates to the technical field of light-emitting modules, in particular to an abyss mirror. Background Technique

[0002] An abyss mirror, also known as a thousand-layer mirror, is a light-emitting product with a display effect. When in use, it can form a visual effect of infinite extension layer by layer, that is, the abyss effect. The basic principle of the abyss mirror is that the light emitted by the light source is projected onto a semi-transparent mirror (also known as coated glass). Part of the light is transmitted through the semi-transparent mirror, while the other part of the light is reflected back. The light reflected back by the semi-transparent mirror is irradiated onto the reflector, and then reflected by the reflector onto the semi-transparent mirror, and then the above-mentioned transmission and reflection processes are repeated to form the abyss effect.

[0003] In the design of traditional abyss mirrors, the light source is generally arranged between the semi-transparent mirror and the reflector, and the light-emitting units (such as LED lamp beads) on the light source need to form a frame-shaped array, and the pattern to be projected is printed on the pattern carrier plate located between the semi-transparent mirror and the emitter mirror. The light emitted by the light source distributed in a frame shape penetrates the pattern carrier plate to light up the entire pattern carrier plate. At the same time, it also lights up the periphery of the display area (in some designs, if there is no need to project a pattern, the pattern carrier plate is deleted, and only the visual effect of lighting up the periphery of the display area is achieved). The disadvantage of this traditional design is that the frame-shaped light source requires a large number of light-emitting units to be composed (because the light source needs to light up the entire periphery of the display area, so if the area of the display area of the abyss mirror is larger, the corresponding perimeter of the periphery is larger, and the more light-emitting units are required), making it difficult to reduce the power consumption of the light source and unable to be applicable to low-power application scenarios (for example, when applied to a graphics card, under the limitation of the total power consumption, the power consumption allowed to be provided to the abyss mirror is very small, otherwise it will affect the operation of the graphics card). Content of the Utility Model

[0004] Based on this, the utility model provides an abyss mirror, which integrates the traditional pattern carrier plate and the reflector, adjusts the installation position of the light source board, and introduces a light guide member between the light source board and the reflector to expand the irradiation range of the light source array and improve the uniformity of light distribution, so that the light source board emits light from the back of the reflector, and uses the light-transmitting area on the reflector to form the required projected pattern. On the premise of the same display area, the number requirement of the light-emitting units is reduced by more than 50%, thereby reducing the power consumption of the light source and making the product applicable to low-power application scenarios.

[0005] An abyss mirror, comprising:

[0006] A light source board; the light source board is provided with a plurality of light-emitting units distributed in a linear array;

[0007] A light guide member disposed parallel to the light source board; a receiving groove and a surrounding edge are provided on a side of the light guide member facing away from the light source board; the surrounding edge is disposed around the periphery of the receiving groove;

[0008] A reflecting mirror mounted on the light guide member; the reflecting mirror is located in the receiving groove and disposed parallel to the light source board; the reflecting mirror is provided with a light-transmitting area and a light-shielding area; the shape of the light-transmitting area is the same as the shape of the pattern required to be projected by the product; and

[0009] A half mirror disposed parallel to the reflecting mirror; the half mirror is located on a side of the reflecting mirror facing away from the light source board, and the half mirror covers the receiving groove and the surrounding edge.

[0010] For the above-mentioned abyss mirror, during operation, multiple light-emitting units on the light source board form a linear light source array, and the light emitted by the light-emitting units irradiates on the light guide member. Under the guidance of the light guide member, part of the light enters the receiving groove and irradiates on the back surface of the reflecting mirror, while the other part of the light is directly emitted from the surrounding edge and then directly irradiates on the half mirror. For the light irradiating on the back surface of the reflecting mirror, part of it directly irradiates on the half mirror through the light-transmitting area, while the other part is intercepted by the light-shielding area. Finally, the user can observe from outside the half mirror a light-emitting area corresponding to the shape of the surrounding edge and a light-emitting pattern corresponding to the shape of the light-transmitting area. Through the above design, the traditional pattern carrier plate and the reflecting mirror are integrated, the installation position of the light source board is adjusted, and a light guide member is introduced between the light source board and the reflecting mirror to expand the irradiation range of the light source array and improve the uniformity of light distribution, so that the light source board emits light from the back surface of the reflecting mirror, and the required projected pattern is formed by using the light-transmitting area on the reflecting mirror. On the premise of the same display area, the number requirement of the light-emitting units is reduced by more than 50%, thereby reducing the power consumption of the light source, so that the product can be applied to low-power application scenarios.

[0011] In one embodiment, each light-emitting unit is located at the midline position of the light source board. Setting the light-emitting units at the midline position of the light source board enables the light to be emitted from the midline position of the product as much as possible, which is beneficial to improving the uniformity of light efficiency.

[0012] In one embodiment, the abyss mirror further includes: a first base and a middle frame respectively connected to the light guide member; the light guide member is clamped between the middle frame and the first base; the light source board is located between the first base and the light guide member, and the half mirror is mounted on the middle frame. Clamping and fixing the light guide member by using the middle frame and the first base has a simple structure and reduces the product cost and assembly difficulty.

[0013] In one embodiment, both the middle frame and the first base are light-shielding structures. By using the light-shielding design of the middle frame and the first base, when the light source board is lit, a light-emitting area can also be formed on the corresponding peripheral side of the product for the peripheral side of the light guide member.

[0014] In one embodiment, the middle frame and the light guide member are detachably connected, and the reflecting mirror is detachably mounted on the light guide member. When the reflecting mirror needs to be replaced, first detach the half mirror together with the middle frame, and then remove the reflecting mirror for replacement. The disassembly and assembly are convenient. By replacing different reflecting mirrors, the personalized customization needs of users can be met.

[0015] In one embodiment, the abyssal mirror further includes: a second base connecting the light guide member and a face cover connecting the second base; a sealed cavity is formed between the second base and the face cover; the light source board, the light guide member, the reflecting mirror, and the half mirror are all located in the sealed cavity; the light source board is attached to the bottom surface of the second base; the face cover is provided with a first light-transmitting portion covering the half mirror. Using the sealed cavity structure formed by the second base and the face cover, the light source board, the light guide member, the reflecting mirror, and the half mirror are hermetically installed and protected, playing a role in moisture-proof and dust-proof protection.

[0016] In one embodiment, the second base and the face cover are detachably connected, and a sealing ring is provided at the connection between the second base and the face cover. Using the detachable connection structure and the sealing ring, both the requirements of sealing protection and quick disassembly and assembly are met.

[0017] In one embodiment, the second base and the face cover are connected by snap connection, or magnetic attraction connection, or screw connection.

[0018] In one embodiment, both the reflecting mirror and the half mirror are installed on the light guide member in a detachable connection manner. After the second base and the face cover are disassembled, the half mirror and the reflecting mirror can be disassembled in sequence, so as to replace different reflecting mirrors and meet the personalized customization needs of users.

[0019] In one embodiment, the outer wall of the peripheral side of the light guide member fits with the inner wall of the peripheral side of the face cover, and the peripheral side of the face cover is provided with a second light-transmitting portion covering the peripheral side of the light guide member. Using the second light-transmitting portion of the face cover, when the light source board is lit, a light-emitting area can also be formed on the peripheral side of the product corresponding to the peripheral side of the light guide member.

[0045] Embodiment 1

[0046] As Figures 1 to 3 shown, it is the abyss mirror 100 of an embodiment of the present utility model.

[0047] As Figures 1 to 3 shown, the abyss mirror 100 includes: a light source board 10, a light guide member 20 disposed parallel to the light source board 10, a reflecting mirror 30 mounted on the light guide member 20, and a semi-transparent mirror 40 disposed parallel to the reflecting mirror 30. During operation, the light source board 10 emits light, which is then diffused and homogenized by the light guide member 20, and the light guide member 20 is also used to form the light-emitting periphery required for the light effect. The reflecting mirror 30 has a dual function. One is to be partially transparent to form the pattern required for the light effect, and the other is to cooperate with the semi-transparent mirror 40 to form the abyss effect.

[0048] Below, in combination with Figures 1 to 3 , the above-mentioned abyss mirror 100 will be further described.

[0049] As Figure 2 and Figure 3 shown, the light source board 10 is provided with a plurality of light-emitting units 11 distributed in a linear array. Based on the working principle of this solution, the linear light source array formed by the plurality of light-emitting units 11 can be disposed at any position on the front surface of the light source board 10, such as at the edge, the center line, the diagonal line, and between the edge and the center line, etc. Preferably, as Figure 2 shown, in this embodiment, each light-emitting unit 11 is located at the center line position of the light source board 10. Setting the light-emitting unit 11 at the center line position of the light source board 10 enables the light to be emitted from the center line position of the product as much as possible, which is beneficial to improving the uniformity of the light effect. In addition, in this embodiment, the light-emitting unit 11 is an LED lamp bead.

[0050] As Figure 2 and Figure 3 shown, the side of the light guide member 20 facing away from the light source board 10 is provided with a receiving groove 21 and a surrounding edge 22. The surrounding edge 22 is disposed around the periphery of the receiving groove 21. As Figure 2As shown, in this embodiment, a downwardly concave receiving groove 21 is formed at the top of the light guide member 20. At the same time, a surrounding edge 22 is provided at the top of the light guide member 20, surrounding the periphery of the receiving groove 21, and the surrounding edge 22 protrudes upward relative to the opening of the receiving groove 21.

[0051] As Figure 2 and Figure 3 shown, the mirror 30 is located in the receiving groove 21 and is arranged parallel to the light source board 10. The mirror 30 is provided with a light-transmitting area (not shown in the figure) and a light-shielding area (not shown in the figure). The shape of the light-transmitting area is the same as the shape of the pattern required to be projected by the product. In this embodiment, the mirror 30 can be obtained by modifying a common mirror. For example, the silver-plated layer on the back of the mirror is processed, and by removing specific areas on the silver-plated layer, a light-transmitting area is formed on the back of the mirror.

[0052] As Figure 2 and Figure 3 shown, the half mirror 40 is located on the side of the mirror 30 facing away from the light source board 10, and the half mirror 40 covers the receiving groove 21 and the surrounding edge 22.

[0053] As Figures 1 to 3 shown, in this embodiment, the abyss mirror 100 may further include: a first base 50 and a middle frame 60 respectively connected to the light guide member 20. The light guide member 20 is clamped between the middle frame 60 and the first base 50. The light source board 10 is located between the first base 50 and the light guide member 20, and the half mirror 40 is mounted on the middle frame 60. The light guide member 20 is clamped and fixed by the middle frame 60 and the first base 50, with a simple structure, reducing the product cost and assembly difficulty.

[0054] Further, in this embodiment, as Figure 3 shown, both the middle frame 60 and the first base 50 are light-shielding structures. By using the light-shielding design of the middle frame 60 and the first base 50, when the light source board 10 is lit, a light-emitting area can also be formed on the peripheral side of the product corresponding to the peripheral side of the light guide member 20.

[0055] In order to facilitate disassembly and assembly and meet the needs of users' personalized customization, in other embodiments, the middle frame 60 and the light guide member 20 are detachably connected, and the mirror 30 is detachably mounted on the light guide member 20. When the mirror 30 needs to be replaced, first detach the half mirror 40 together with the middle frame 60, and then remove the mirror 30 located in the receiving groove 21 for replacement. The disassembly and assembly are convenient, and by replacing different mirrors 30, the needs of users' personalized customization can be met. For example, the middle frame 60 and the light guide member 20 can be connected by snap connection, magnetic attraction connection, screw connection, etc.

[0056] Brief description of the working principle:

[0057] Combined with Figure 2 andFigure 3 As shown in the figure, during operation, multiple light-emitting units 11 on the light source board 10 form a linear light source array, and the light emitted by the light-emitting units 11 irradiates on the light guide member 20. Under the guidance of the light guide member 20, part of the light enters the receiving groove 21 and irradiates on the back surface of the reflector 30, while the other part of the light directly irradiates on the half mirror 40 after being emitted from the surrounding edge 22. For the light irradiating on the back surface of the reflector 30, part of it directly irradiates on the half mirror 40 through the light-transmitting area, while the other part is blocked by the light-shielding area. Finally, the user can observe from outside the half mirror 40 a light-emitting area corresponding to the shape of the surrounding edge 22 and a light-emitting pattern corresponding to the shape of the light-transmitting area.

[0058] For the above-mentioned abyss mirror 100, the traditional pattern carrier plate and the reflector 30 are integrated, the installation position of the light source board 10 is adjusted, and a light guide member 20 is introduced between the light source board 10 and the reflector 30 to expand the irradiation range of the light source array and improve the uniformity of light distribution, so that the light source board 10 emits light from the back surface of the reflector 30, and the required projected pattern is formed by using the light-transmitting area on the reflector 30. On the premise of the same display area, the number requirement of the light-emitting units 11 is reduced by more than 50%, thereby reducing the power consumption of the light source, so that the product can be applicable to low-power application scenarios.

[0059] Embodiment 2

[0060] As Figures 4 to 8 shown, it is the abyss mirror 100 of another embodiment of the present utility model.

[0061] The difference between this embodiment and Embodiment 1 is that: as Figures 4 to 6 shown, in this embodiment, the abyss mirror 100 further includes: a second base 70 connecting the light guide member 20 and a face cover 80 connecting the second base 70.

[0062] As Figure 7 and Figure 8 shown, a sealed cavity is formed between the second base 70 and the face cover 80. The light source board 10, the light guide member 20, the reflector 30, and the half mirror 40 are all located in the sealed cavity. The light source board 10 is attached to the bottom surface of the second base 70. The face cover 80 is provided with a first light-transmitting portion 81 covering the half mirror 40. By using the sealed cavity structure formed by the second base 70 and the face cover 80, the light source board 10, the light guide member 20, the reflector 30, and the half mirror 40 are hermetically installed and protected, playing a role in moisture-proof and dust-proof protection.

[0063] Since the light effect generated by the product is relative to the design of the light-transmitting area on the reflector 30, in order to allow the manufacturer or user to adjust the abyss mirror 100 according to requirements, as Figure 7 and Figure 8As shown, in this embodiment, the connection between the second base 70 and the face cover 80 is detachable, and a sealing ring 91 is provided at the connection between the second base 70 and the face cover 80. By using the detachable connection structure and the sealing ring 91, both the requirements of sealing protection and rapid disassembly and assembly are met.

[0064] Further, the connection between the second base 70 and the face cover 80 is a snap connection, or a magnetic attraction connection, or a screw connection. For example, as Figure 7 and Figure 8 shown, in this embodiment, a snap connection is adopted between the second base 70 and the face cover 80.

[0065] As Figures 6 to 8 shown, in this embodiment, the half mirror 40 is attached to the light guide member 20 by double-sided tape 92. Therefore, the light guide member 20, the reflector 30, and the light guide member 20 form a fixed module. When it is necessary to replace the light effect, the entire fixed module needs to be replaced. Based on this, in other embodiments, in order to enable the manufacturer or user to adjust the light effect on the premise of only replacing the reflector 30 according to requirements, both the reflector 30 and the half mirror 40 are installed on the light guide member 20 in a detachable manner. After disassembling the second base 70 and the face cover 80, the half mirror 40 and the reflector 30 can be disassembled in sequence, so as to replace different reflectors 30 to meet the personalized customization needs of users. For example, the reflector 30 can be snap-connected to the light guide member 20, and the half mirror 40 can be slidably connected to the light guide member 20 through a chute on the light guide member 20 (installed in a horizontal insertion manner).

[0066] Similar to Embodiment 1, in order to form a light-emitting area on the peripheral side of the product, as Figure 8 shown, in this embodiment, the outer wall of the peripheral side of the light guide member 20 is attached to the inner wall of the peripheral side of the face cover 80, and a second light-transmitting portion 82 covering the peripheral side of the light guide member 20 is provided on the peripheral side of the face cover 80. By using the second light-transmitting portion 82 of the face cover 80, when the light source board 10 is lit, a light-emitting area corresponding to the peripheral side of the light guide member 20 can also be formed on the peripheral side of the product.

[0067] In addition, as Figure 5 shown, a wire routing hole 71 is opened at the bottom of the second base 70 for the wire connecting the light source board 10 to route. At the same time, after the wire routing installation is completed, a sealant filling treatment is performed at the wire routing hole 71.

[0068] Other structures of this embodiment are the same as those of Embodiment 1 and can also achieve the beneficial effects of Embodiment 1, which will not be elaborated here.

[0069] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0070] The above embodiments only express the preferred embodiments of the present utility model, and the description is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
