Description

Technical Field

[0002] At present, as a key component of modern lighting equipment, linear light devices are widely used in various products such as ceiling lamps and decorative lamps. The traditional way of fixing the light source module is usually to use screw mechanical connection or double-sided adhesive to achieve assembly with the lamp body.

[0003] However, this type of fixing method has obvious shortcomings. First, the installation process of screw fixing is cumbersome, which is not only time-consuming and labor-intensive, but also has a certain impact on production efficiency and increases the cost of manual assembly. Secondly, frequent disassembly and assembly may cause the screws to loosen or fail, which in turn affects the stability and safety of the light source module. On the other hand, although the use of double-sided adhesive bonding simplifies the assembly steps, after long-term use, due to factors such as thermal expansion and contraction and aging, the bonding effect may weaken, causing the light source module to easily fall off, and it is difficult to peel off during replacement or maintenance, which can easily damage the lamp body or the light source module itself.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. It should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0025] At present, the light source module is generally fixed with screws or double-sided adhesive to be assembled with the lamp body, but such methods are cumbersome to operate, costly and have poor long-term stability. The utility model focuses on the auxiliary light-emitting components of lamp decoration, and proposes a design scheme in which the light source module is first integrated and fixed with the diffuser cover and the transparent cover, and then integrated into the lamp body, realizing a screw-free installation structure, which significantly improves the convenience and stability of installation.

[0026] Combine the following Figure 1-Figure 4 The specific implementation modes of the linear light emitting device and the lighting equipment of the present invention are described.

[0027] like Figure 1 and Figure 4As shown, the utility model provides a linear light-emitting device, including: a frame 10, which is arranged on the base of the lighting device; a transparent cover 20, which is snap-fitted with the frame 10, and a receiving groove 21 extending along the projection shape of the frame 10 is provided on the side of the transparent cover 20 facing the frame 10; a diffusion cover 30, which is arranged between the frame 10 and the transparent cover 20, and a part of the shape of the diffusion cover 30 is adapted to the receiving groove 21 so that it can be placed in the receiving groove 21, and the diffusion cover 30 is snap-fitted with the transparent cover 20 and the frame 10 respectively; a light source module 40, which is arranged between the diffusion cover 30 and the frame 10, and the light-emitting side of the light source module 40 faces the diffusion cover 30.

[0028] Specifically, the linear light-emitting device mainly includes four key parts: one is a frame 10 arranged on the base of the lighting equipment, which plays a core role of support and positioning; the second is a transparent cover 20 that cooperates with the frame 10 by snapping, and a receiving groove 21 extending according to the projection shape of the frame 10 is provided on the side facing the frame 10; the third is a diffusion cover 30 that matches the shape of the receiving groove 21 of the transparent cover 20 and can be stably embedded therein, and the diffusion cover 30 is located between the frame 10 and the transparent cover 20, and is snap-fitted with both of them to ensure the compactness and stability of the structure; the fourth is a light source module 40 arranged in the interlayer between the diffusion cover 30 and the frame 10, and its light-emitting side faces the diffusion cover 30, which is conducive to the effective transmission and uniform diffusion of light.

[0029] In practical applications, the linear light-emitting device of the utility model adopts an innovative modular assembly concept. First, the transparent cover 20, the diffusion cover 30 and the light source module 40 are pre-integrated into one, without the need for traditional fasteners such as screws. Then, in the final assembly stage, thanks to the fact that both the transparent cover 20 and the diffusion cover 30 can be snap-fitted with the frame 10, the connection with the frame 10 on the base can be easily completed. The assembly process is simple and efficient, effectively avoiding the cumbersome procedures brought about by traditional screw fixing. At the same time, due to the use of a snap-fit ​​structure, the structure can remain stable during long-term use, and there will be no loosening due to the passage of time, which greatly improves the assembly efficiency and long-term operation stability of the lighting equipment.

[0030] Through the above-mentioned structural design and assembly method, not only the assembly efficiency of the lighting equipment is significantly improved, but also the overall stability and consistency of the device are enhanced, which helps to reduce production costs and maintenance difficulties, thereby effectively promoting the product performance improvement and market application value of the lighting equipment.

[0031] The frame 10 can be designed to be integrated with the base of the lighting device to enhance the integrity and stability of the structure. In a preferred embodiment, the frame 10 can be installed on the lamp holder in a flexible and convenient detachable installation manner, such as a plug-in, snap-on or magnetic connection.

[0032] like Figure 4As shown, in the wire light-emitting device of the present invention, the power line and the electric control line equipped with the light source module 40 can be led out to the outside through the reserved gap between the frame 10 and the diffuser cover 30, or directly through the wire holes preset in the frame 10 or the diffuser cover 30. The cables extending from the inside of the device can not only adopt the common male and female terminal connection method, but also adopt other suitable connection forms according to actual needs, so as to connect with the external power supply for power supply, or receive control signal input, so as to ensure that the component can smoothly realize the light-emitting function, and has good adaptability and expansibility.

[0033] like Figure 1 and Figure 2 As shown, according to a linear light emitting device provided by the present invention, a light mixing groove 31 is provided on the side of the diffusion cover 30 facing the frame 10; the light source module 40 is located at the top opening of the light mixing groove 31 to form a light mixing space between the light source module 40 and the light mixing groove 31. The light mixing space can optimize light distribution and improve light effect.

[0034] Specifically, the light source module 40 is arranged at the top opening of the light mixing groove 31, so that a space dedicated to mixing light is formed between the light source module 40 and the light mixing groove 31. When the light source module 40 emits light, the light passes through the light mixing groove 31 on the diffusion cover 30, and light of different angles and intensities overlap and disperse in this space, thereby achieving a more uniform light distribution and a soft lighting effect, which is conducive to reducing glare and enhancing visual comfort, and can make the light emitted by the light source more consistent and smooth in the irradiated area, thereby improving the overall lighting quality and aesthetic effect of the lighting device.

[0035] like Figure 1 and Figure 3 As shown, according to a linear light-emitting device provided by the utility model, the light source module 40 extends along the light mixing groove 31, and can make full use of the spatial structure of the light mixing groove 31 to mix and diffuse the light. The width of the light source module 40 is preferably less than or equal to the width of the top opening of the light mixing groove 31, which can avoid excessive fitting affecting the assembly, or causing the light source module 40 to be compressed and damaged during the assembly process. At the same time, a plurality of side edge extensions 41 are respectively provided on both sides of the light source module 40. In the assembled state, the side edge extensions 41 are supported on both sides of the top opening of the light mixing groove 31 to achieve support and fixation of the light source module 40.

[0036] Specifically, the light source module 40 is arranged to extend along the direction of the light mixing groove 31, making full use of the internal space characteristics of the light mixing groove 31, so that the light can be effectively mixed and diffused after entering the light mixing groove 31, thereby improving the uniformity and beauty of the lighting effect. In order to ensure the good fit between the light source module 40 and the light mixing groove 31 and the safety of the assembly process, the width of the main part of the light source module 40 is preferably set to be less than or equal to the width of the top opening of the light mixing groove 31, so as to prevent the assembly difficulties caused by the tight fit between the frame 10 and the diffusion cover 30, and also avoid the problem of damage to the light source module 40 due to excessive pressure during the assembly process. In addition, a plurality of side edge extensions 41 are provided on both sides of the light source module 40. During assembly, these side edge extensions 41 will form contact with both sides of the top opening of the light mixing groove 31 and provide support, thereby achieving a stable and reliable positioning of the light source module 40.

[0037] The extending shapes of the receiving groove 21 of the transparent cover 20 and the light mixing groove 31 of the diffusion cover 30 are preferably circular or rectangular, and the light source module 40 can be one, extending in a corresponding ring or rectangle, or as shown in FIG. Figure 3 As shown, there may be multiple light source modules 40 , which are arranged in sequence along the extending direction of the receiving groove 21 and the light mixing groove 31 , thereby reducing the manufacturing difficulty and maintenance cost of a single light source module 40 .

[0038] like Figure 1 and Figure 4 As shown, according to a linear light-emitting device provided by the utility model, the frame 10 is provided with an inner edge pressing plate 11; in the assembled state, the inner edge pressing plate 11 is pressed tightly against the upper surface of the light source module 40. The inner edge pressing plate 11 can be pressed tightly against the upper surface of the light source module 40, and form an upper and lower cooperation with the diffusion cover 30 below, and jointly clamp and fix the light source module 40. It can not only ensure the stable positioning of the light source module 40 in the vertical direction and prevent it from shaking or detaching during use, but also help to strengthen the rigidity and sealing of the overall structure, and improve the working efficiency and life of the light-emitting device. Through the synergistic effect of the inner edge pressing plate 11 and the diffusion cover 30, an efficient and safe fixing method for the light source module 40 is achieved.

[0039] Furthermore, the frame 10 can be a structural frame with good thermal conductivity. During assembly, the inner edge pressure plate 11 is tightly pressed against the upper surface of the light source module 40, which not only ensures the stable installation of the light source module 40, but also effectively reduces the contact gap between the light source module 40 and the frame 10, which is conducive to the rapid transfer of heat. Through this close fit, the heat generated by the light source module 40 can be transferred to the frame 10 more quickly, and the good thermal conductivity of the frame 10 itself can achieve efficient heat dissipation of the light source module 40, thereby extending the service life of the light source module 40.

[0040] like Figure 1 and Figure 3 As shown, according to a linear light-emitting device provided by the utility model, the diffusion cover 30 is provided with a vertical baffle 32, and the vertical baffle 32 stops at one side of the light source module 40 in the horizontal direction. On the one hand, the vertical baffle 32 acts as a barrier, effectively preventing the light emitted by the light source module 40 from leaking out directly without diffusion, ensuring that the light can be better evenly mixed and scattered through the diffusion cover 30. On the other hand, the vertical baffle 32 also acts as a physical limiting element, providing a horizontal limit to the light source module 40, ensuring that the light source module 40 is accurately positioned after installation, reducing the difficulty of assembly.

[0041] Furthermore, if Figure 3 As shown, according to a linear light-emitting device provided by the utility model, the vertical baffle 32 has a notch structure; at the notch structure, the diffuser cover 30 is provided with a positioning post 33; at least a portion of the side edge extension 41 is provided with a positioning hole adapted to the positioning post 33. Specifically, the diffuser cover 30 is provided with a positioning post 33 at the location of its notch structure, and the side edge extension 41 of the light source module 40 is provided with a positioning hole that matches the positioning post 33. During the assembly process, the positioning post 33 can be accurately inserted into the positioning hole of the side edge extension 41, thereby ensuring the precise positioning between the light source module 40 and the diffuser cover 30. The vertical baffle 32 that cooperates with the diffuser cover 30 can ensure that the light source module 40 will not shake after being placed in place, which is beneficial to the subsequent installation.

[0042] like Figure 1 and Figure 4 As shown, according to a linear light-emitting device provided by the utility model, a first undercut structure 34 is provided on one side of the vertical baffle plate 32 facing the inner edge of the frame 10; in the assembled state, a snap fit is formed between the first undercut structure 34 and the inner edge of the frame 10. The first undercut structure 34 is provided on one side of the vertical baffle plate 32 facing the inner edge of the frame 10, and can be in the form of a lateral triangular protrusion or a hook-shaped design. When the device is in the assembled state, the first undercut structure 34 interacts with the inner edge of the frame 10 (such as the inner edge pressure plate 11) to form a stable snap fit.

[0043] By snapping the undercut structure with the inner edge of the frame 10, the connection strength between the diffuser cover 30 and the frame 10 can be increased, effectively preventing the diffuser cover 30 from being displaced or detached during normal use. In addition, the snap-fitting method simplifies the assembly process, does not require additional fasteners, and reduces assembly difficulty and cost.

[0044] like Figure 1 and Figure 3As shown, according to a linear light-emitting device provided by the utility model, the transparent cover 20 is provided with a step structure 22 adapted to the bottom of the outer edge of the frame 10; the step structure 22 is provided with a second inverted structure 23; in the assembled state, the second inverted structure 23 forms a snap fit with the outer edge of the frame 10. When the device is in the assembled state, the step structure 22 of the transparent cover 20 is butted against the outer edge of the frame 10, and the second inverted structure 23 and the outer edge of the frame 10 are engaged with each other, forming a snap fit similar to a lock, ensuring that the transparent cover 20 and the frame 10 can be tightly connected to prevent loosening or falling off. The inverted snap fit simplifies the assembly and disassembly process without the need for additional screws or other fasteners.

[0045] like Figure 1 and Figure 2 As shown, according to a linear light-emitting device provided by the utility model, the diffuser cover 30 is provided with a horizontal extension part 35, and the horizontal extension part 35 is provided with a snap-in hole 36; the transparent cover 20 is provided with a third inverted buckle structure 24 adapted to the snap-in hole 36; in the assembled state, the third inverted buckle structure 24 is inserted into the snap-in hole 36 from bottom to top to form a snap-in fit. The horizontal extension part 35 is prefabricated with the snap-in hole 36, and the transparent cover 20 is provided with a corresponding third inverted buckle structure 24. In the actual assembly process, the third inverted buckle structure 24 on the transparent cover 20 will be inserted from bottom to top into the snap-in hole 36 of the horizontal extension part 35 of the diffuser cover 30, and the two will be precisely docked and form a stable snap-in fit.

[0046] Preferably, if Figure 1 As shown, the third inverted structure 24 and the first inverted structure 34 are designed in opposite directions in the horizontal direction to enhance the connection stability between the three key components of the frame 10, the diffuser cover 30 and the transparent cover 20. Specifically, the first inverted structure 34 is applied to the vertical baffle 32 and the inner edge area of ​​the frame 10, and the diffuser cover 30 is accurately limited and fixed in both the horizontal and vertical directions through snap-fitting; while the third inverted structure 24 plays a role between the transparent cover 20 and the horizontal extension 35 of the diffuser cover 30, and the two are also tightly combined by snap-fitting. These two inverted structures adopt a reverse complementary matching method, which not only enhances the locking strength between the components from different connection levels, but also effectively prevents the loosening or position displacement of components that may occur under various usage environments and changing conditions, thereby greatly improving the structural rigidity and service life of the entire linear light-emitting device.

[0047] The utility model also provides a lighting device, comprising the linear light-emitting device of any one of the above embodiments, and the lighting device is a ceiling lamp or a decorative lamp.

[0048] Preferably, the core component of the lighting device is the linear light-emitting device provided by the utility model. The frame 10 of the linear light-emitting device is installed on the base of the lighting device, and the transparent cover 20 is tightly combined with the frame 10 by snap-fitting. The inner side of the transparent cover 20 is provided with a receiving groove 21 matching the shape of the frame 10. The diffusion cover 30 is embedded in the receiving groove 21, and is snap-fitted with the transparent cover 20 and the frame 10 to ensure the convenience and stability of assembly. The light source module 40 is fixed between the diffusion cover 30 and the frame 10, and the light source faces the diffusion cover 30 to achieve efficient diffusion and uniform distribution of light.

[0049] In order to further optimize the fixation and heat dissipation of the light source module 40, an inner edge pressing plate 11 is provided inside the frame 10, which presses the upper surface of the light source module 40 after assembly, and together with the diffusion cover 30, forms the upper and lower limit fixation of the light source module 40. At the same time, the material of the frame 10 has excellent thermal conductivity, which helps the light source module 40 to dissipate heat in time. A light mixing groove 31 is specially designed inside the diffusion cover 30, and the light source module 40 is precisely matched with the top opening of the light mixing groove 31, and the light mixing space formed therebetween is conducive to the mixing and diffusion of light.

[0050] The vertical baffle 32 on the diffusion cover 30 not only limits the position of the light source module 40 to prevent light from overflowing, but also forms a snap connection with the inner edge of the frame 10 through the first undercut structure 34 to enhance the connection stability. The transparent cover 20 is provided with a step structure 22 adapted to the bottom of the outer edge of the frame 10, and a second undercut structure 23 is designed on the step, which is snapped with the outer edge of the frame 10 during assembly, further ensuring the stable combination of the transparent cover 20 and the frame 10.

[0051] In addition, the diffusion cover 30 is also provided with a horizontal extension portion 35, which is provided with a snap-fit ​​hole 36, and the transparent cover 20 is provided with a third inverted structure 24 adapted thereto at a corresponding position, and snap-fit ​​is formed by inserting from bottom to top during assembly.

[0052] To sum up, the lighting equipment provided by the utility model, by selecting the linear light-emitting device of any embodiment, with its sophisticated structural design and multiple stable clip-on fixing methods, not only simplifies the assembly process and reduces costs, but also effectively improves the structural stability and durability of the lighting equipment.
