Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a double-sided light for desk furniture and the desk furniture itself. Background Technology

[0002] Desk furniture generally includes study desks, workbenches, bookshelves, and other products, and many desks are equipped with lamps for illumination. However, common lighting fixtures can only ensure that the core area used by the user (such as part of the desk's surface) achieves a level of simulated sunlight, while the surrounding environment cannot achieve a good simulation of sunlight. This results in significant changes in brightness between the user's core area and the surrounding environment, which can easily cause discomfort and eye fatigue when the user's gaze shifts, and over time, may even affect the user's eyesight. To address this, double-sided lighting products have emerged on the market. These lamps can illuminate both the core area of ​​the desk and the surrounding environment, reducing eye discomfort and fatigue when the user's gaze shifts.

[0003] However, current double-sided light products typically use two sets of light sources positioned back-to-back to illuminate the upper and lower sides respectively. This approach suffers from uneven light output and the lamp housing overheating. Utility Model Content

[0004] The purpose of this utility model is to provide a double-sided light-emitting lamp and a desk furniture for desk furniture, which can improve the uniformity of light and enhance heat dissipation efficiency while achieving double-sided light emission.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-sided light-emitting lamp for desk furniture, comprising a lamp housing, a light guide plate, a first light-emitting component, a second light-emitting component, a first light-emitting plate, and a second light-emitting plate. The lamp housing forms a mounting cavity and an upper light-emitting port and a lower light-emitting port communicating with the outside. The light guide plate, the first light-emitting component, the second light-emitting component, the first light-emitting plate, and the second light-emitting plate are all positioned within the mounting cavity. The first light-emitting plate, the light guide plate, and the second light-emitting plate are arranged in a sequentially stacked manner, with the first light-emitting plate located on the side of the upper light-emitting port and the second light-emitting plate located on the side of the lower light-emitting port. The first light-emitting component and the second light-emitting component are respectively located on the left and right sides of the light guide plate along a set direction, with the light-emitting side of the first light-emitting component facing one end face of the light guide plate and the light-emitting side of the second light-emitting component facing the other end face of the light guide plate. The set direction is perpendicular to the thickness direction of the light guide plate.

[0007] Preferably, the first light-emitting plate includes a prism plate and / or a diffuser plate and / or a diffuser film, and the second light-emitting plate includes a prism plate and / or a diffuser plate and / or a diffuser film.

[0008] Preferably, the lamp housing includes a top plate, a bottom plate, a first side plate, and a second side plate. The top ends of the first side plate and the second side plate are respectively fixed to the two sides of the top plate. The bottom plate is fixed to the bottom ends of the first side plate and the second side plate. The top plate, the bottom plate, the first side plate, and the second side plate together form the mounting cavity.

[0009] Preferably, the base plate includes a first bent plate fixed to a first side plate and a second bent plate fixed to a second side plate. The top plate, the first side plate, and the first bent plate form a first assembly groove, and the top plate, the second side plate, and the second bent plate form a second assembly groove. The two ends of the light guide plate, the first light emitting plate, and the second light emitting plate are respectively inserted into the first assembly groove and the second assembly groove. The first light-emitting component is disposed in the first assembly groove, and the second light-emitting component is disposed in the second assembly groove.

[0010] Preferably, the gap between the first bending plate and the second bending plate forms the lower light-emitting port, and the upper light-emitting port is an opening located in the middle of the top plate.

[0011] Preferably, the first light-emitting component includes a first lamp board and a first light source electrically connected to the first lamp board, and the second light-emitting component includes a second lamp board and a second light source electrically connected to the second lamp board. The first lamp board and the second lamp board are respectively fixedly disposed on the inner wall of the first side plate and the inner wall of the second side plate.

[0012] Preferably, the lamp housing has assembly ports formed at its front and rear ends along the set direction, and the double-sided light lamp also includes an end cap that is detachably installed at the assembly port.

[0013] Preferably, the end cap includes a cover plate and a positioning block formed on the cover plate, the positioning block being adapted to the assembly port, the positioning block extending into the mounting cavity from the assembly port, and the cover plate being fixedly connected to the lamp housing by a snap-fit ​​structure and / or screws.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The first and second light-emitting components are respectively positioned on the left and right sides of the light guide plate along a predetermined direction, with the light-emitting sides of the first and second light-emitting components facing the two end faces of the light guide plate. In this way, the light emitted by the first and second light-emitting components enters the light guide plate in a direction parallel to the light guide plate, and after being diffused by the light guide plate, the light is guided to the first and second light-emitting plates, allowing the light to be emitted uniformly from the first and second light-emitting plates. Furthermore, since the first and second light-emitting components are located on opposite sides of the light guide plate with a large distance between them, the heat emitted is less likely to accumulate, thus enabling faster heat dissipation.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Unless otherwise specified, the materials and equipment used in this embodiment are all commercially available. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0027] In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a connection through an intermediary, or a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] The related double-sided light-emitting lamps use a scheme where two sets of light sources face back to back, with the light sources directly shining on the corresponding light-transmitting plates. Because the light sources shine directly on the light-transmitting plates, regardless of whether the light sources are LED chips or LED strips, the brightness of the part of the light-transmitting plate perpendicular to the light source will be brighter than the brightness of other parts of the light-transmitting plate, resulting in uneven brightness of the light-transmitting plate. In addition, because the product size cannot be too large, the thickness of the double-sided light-emitting lamp cannot be too large, and the distance between the two sets of light sources is small. When the double-sided light-emitting lamp is working, the heat emitted by the two sets of light sources tends to accumulate between the two sets of light sources, resulting in slow heat dissipation, low heat dissipation efficiency, and a tendency for the double-sided light-emitting lamp to heat up rapidly.

[0030] To address the aforementioned technical problems, this embodiment provides a double-sided light source for desk furniture, such as... Figure 1 , Figure 2 and Figure 3As shown, the double-sided light-emitting lamp includes a lamp housing 1, a light guide plate 2, a first light-emitting component 3, a second light-emitting component 4, a first light-emitting plate 5, and a second light-emitting plate 6. The lamp housing 1 has a mounting cavity and an upper light-emitting port 100 and a lower light-emitting port 132 connecting the mounting cavity to the outside. The light guide plate 2, the first light-emitting component 3, the second light-emitting component 4, the first light-emitting plate 5, and the second light-emitting plate 6 are all positioned within the mounting cavity. The first light-emitting plate 5, the light guide plate 2, and the second light-emitting plate 6 are arranged in a stacked manner, with the first light-emitting plate 5 located on the side of the upper light-emitting port 100 and the second light-emitting plate 6 located on the side of the lower light-emitting port 132. The first light-emitting component 3 and the second light-emitting component 4 are located on the left and right sides of the light guide plate 2 respectively along a predetermined direction, with the light-emitting side of the first light-emitting component 3 facing one end face of the light guide plate 2 and the light-emitting side of the second light-emitting component 4 facing the other end face of the light guide plate 2. The predetermined direction is perpendicular to the thickness direction of the light guide plate 2.

[0031] The light emitted by the first light-emitting component 3 and the second light-emitting component 4 is directed to the first light-emitting plate 5 and the second light-emitting plate 6 respectively through the light guide plate 2, and then emitted from the upper light-emitting port 100 and the lower light-emitting port 132, thereby enabling simultaneous light emission in both the upper and lower directions.

[0032] The double-sided light-emitting lamp provided in this embodiment has a first light-emitting component 3 and a second light-emitting component 4 respectively arranged on the left and right sides of a light guide plate 2 along a predetermined direction, with the light-emitting side of the first light-emitting component 3 and the light-emitting side of the second light-emitting component 4 facing the two end faces of the light guide plate 2 respectively. In this way, the light emitted by the first light-emitting component 3 and the second light-emitting component 4 enters the light guide plate 2 in a direction parallel to the light guide plate 2, and after being diffused by the light guide plate 2, the light is guided to the first light-emitting plate 5 and the second light-emitting plate 6, so that the light can be emitted uniformly from the first light-emitting plate 5 and the second light-emitting plate 6. Furthermore, since the first light-emitting component 3 and the second light-emitting component 4 are located on opposite sides of the light guide plate 2 with a large distance between them, the heat emitted is less likely to accumulate, thus allowing for faster heat dissipation.

[0033] It should be noted that the setting direction mentioned in this embodiment refers to the direction perpendicular to the thickness direction of the light guide plate 2, such as... Figure 1 and Figure 2 As shown in the diagram, the double-sided light-emitting lamp in this embodiment is rectangular in shape, and the length direction of the light guide plate 2 is the predetermined direction. That is, the first light-emitting component 3, the light guide plate 2, and the second light-emitting component 4 are sequentially distributed along the width direction of the light guide plate 2. It is easy to understand that in other optional embodiments, the predetermined direction can also be the width direction of the light guide plate 2. In this case, the first light-emitting component 3, the light guide plate 2, and the second light-emitting component 4 are sequentially distributed along the length direction of the light guide plate 2.

[0034] Specifically, in this embodiment, the first light-emitting plate 5 is a diffusion film, and the second light-emitting plate 6 is a prism plate. In optional embodiments, the first light-emitting plate 5 can also be either a diffusion plate or a prism plate, and the second light-emitting plate 6 can also be either a diffusion film or a diffusion plate. Furthermore, the first light-emitting plate 5 and the second light-emitting plate 6 can also be a combination of two or all of the following: a diffusion plate, a prism plate, and a diffusion film. The first light-emitting plate 5, the light guide plate 2, and the second light-emitting plate 6 can be stacked, or they can be bonded together using optical adhesive.

[0035] In this embodiment, the lamp housing 1 includes a top plate 10, a bottom plate 13, a first side plate 11, and a second side plate 12. The top ends of the first side plate 11 and the second side plate 12 are respectively fixed to the two sides of the top plate 10. The bottom plate 13 is fixed to the bottom ends of the first side plate 11 and the second side plate 12. The top plate 10, bottom plate 13, first side plate 11, and second side plate 12 together form a mounting cavity. Furthermore, in combination with... Figure 2 , Figure 3 and Figure 4 As shown, the base plate 13 includes a first bent plate 130 fixed to the first side plate 11 and a second bent plate 131 fixed to the second side plate 12. The top plate 10, the first side plate 11, and the first bent plate 130 enclose to form a first assembly groove 14, and the top plate 10, the second side plate 12, and the second bent plate 131 enclose to form a second assembly groove 15. The two ends of the light guide plate 2, the first light emitting plate 5, and the second light emitting plate 6 are respectively inserted into the first assembly groove 14 and the second assembly groove 15. The first light-emitting component 3 is disposed in the first assembly groove 14, and the second light-emitting component 4 is disposed in the second assembly groove 15.

[0036] In this embodiment, the first light-emitting component 3 includes a first lamp plate 30 and a first light source 31 electrically connected to the first lamp plate 30. The second light-emitting component 4 includes a second lamp plate 40 and a second light source 41 electrically connected to the second lamp plate 40. The first lamp plate 30 and the second lamp plate 40 are respectively fixedly disposed on the inner wall of the first side plate 11 and the inner wall of the second side plate 12. Specifically, the first lamp plate 30 is bonded and fixed to the inner wall of the first side plate 11, and the second lamp plate 40 is bonded and fixed to the inner wall of the second side plate 12. In this embodiment, the phrase "the light-emitting side of the first light-emitting component 3 faces one side end face of the light guide plate 2, and the light-emitting side of the second light-emitting component 4 faces the other side end face of the light guide plate 2" means that the light emitted by the first light source 31 is perpendicular to the end face of one side of the light guide plate 2, and the light emitted by the second light source 41 is perpendicular to the end face of the other side of the light guide plate 2.

[0037] In this embodiment, both the first light source 31 and the second light source 41 are LED beads. In other optional embodiments, the first light source 31 and the second light source 41 can also be LED strips.

[0038] like Figure 2 and Figure 3 As shown, the light-emitting opening is an opening located in the center of the top plate 10. The bottom plate 13 includes a first bent plate 130 and a second bent plate 131, with the gap between the first bent plate 130 and the second bent plate 131 forming a lower light-emitting opening 132. In other optional embodiments, such as... Figure 6 As shown, the base plate 13 can also be a single piece of plate, and the lower light-emitting port 132 is an opening formed on the base plate 13.

[0039] To facilitate the assembly of the various components in this double-sided light-emitting lamp, in this embodiment, assembly ports 16 are formed at both ends of the lamp housing 1 along a predetermined direction. The double-sided light-emitting lamp also includes end caps 7 detachably installed at the assembly ports 16. By forming assembly ports 16 at both ends of the lamp housing 1, the light guide plate 2, the first light-emitting component 3, the second light-emitting component 4, the first light-emitting plate 5, and the second light-emitting plate 6 can all be inserted into the mounting cavity through the assembly ports 16. Then, the end caps 7 are installed at the assembly ports 16 to seal the assembly ports 16, thereby limiting the position of the light guide plate 2, the first light-emitting component 3, the second light-emitting component 4, the first light-emitting plate 5, and the second light-emitting plate 6, and thus positioning the light guide plate 2, the first light-emitting component 3, the second light-emitting component 4, the first light-emitting plate 5, and the second light-emitting plate 6 within the mounting cavity.

[0040] Combination Figure 2 and Figure 5 As shown in the diagram, the end cap 7 in this embodiment includes a cover plate 70 and a positioning block 71 formed on the cover plate 70. The positioning block 71 is adapted to the assembly port 16 and extends into the mounting cavity from the assembly port 16. The cover plate 70 and the lamp housing 1 are fixedly connected by screws. Specifically, threaded holes are provided on the first side plate 11 and the second side plate 12. After aligning the end cap 7 with the assembly port 16 so that the positioning block 71 is inserted into the mounting cavity, the cover plate 70 fits against the first side plate 11 and the second side plate 12. The cover plate 70 is provided with a through hole. By passing a screw through the through hole and screwing it into the threaded hole, the end cap 7 can be fixedly installed on the lamp housing 1. The positioning block 71 can limit the movement of the light guide plate 2, the first light-emitting component 3, the second light-emitting component 4, the first light-emitting plate 5, and the second light-emitting plate 6. On the other hand, it can play a preliminary positioning role during the assembly of the end cap 7 and the lamp housing 1, which facilitates the assembly operation.

[0041] The double-sided light-emitting lamp provided in this embodiment can be applied to desk furniture. To facilitate the assembly of the double-sided light-emitting lamp with desk furniture, the end cap 7 in this embodiment is provided with mounting holes 700 for installation with desk furniture. Specifically, the mounting hole 700 is a threaded hole; optionally, the mounting hole 700 can also be a pin hole.

[0042] The desk furniture can be a study table, study desk, bookshelf, etc. The double-sided light can be fixedly installed on the desk furniture through the mounting hole 700 on the end cover 7. Under normal circumstances, there is a certain distance between the double-sided light and the desktop, and the second light outlet of the double-sided light faces the desktop.

[0043] Finally, it should be noted that the above embodiments are only optional embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
