Description

Technical Field

[0001] The invention relates to the technical field of LED linear lights, and in particular to a double-sided luminous LED linear light. Background Art

[0002] LED linear lights have different lighting requirements in different application scenarios. For example, when the store needs to focus on illuminating the goods on the shelves, a flat lampshade is selected, which has a wider light distribution, a larger lighting range, and a higher overall brightness. In a general working environment, a double-sided LED linear light is selected to provide a certain range of light, which has a certain soothing function and can reduce the stimulation of light to the eyes and protect the eyes. In office areas with more computer screens (such as design studios or drawing rooms), a grille lampshade is selected to better control the distribution and direction of light, reduce glare, reduce reflection, and reduce screen reflection. It can be seen that the design of existing lamps on the market can only meet the application of a single environment. If the lamp needs to be changed after installation, it must be re-purchased, resulting in a waste of resources.

[0003] The LED linear lights in the prior art mainly include lamps and lampshades. The lampshades and lamps are connected by snap-fit ​​connections. In conventional solutions, the lampshades and lamps can be installed by simply snapping the two snaps together. However, a certain amount of elastic margin must be left between the snaps to allow for the buckles to deform, otherwise the block is prone to breakage. It is understandable that as the elastic margin increases, the larger the gap between the lampshade and the lamp, the more serious the light leakage, which means the lower the light utilization rate. For those skilled in the art, if the light utilization rate is to be increased, the means that can be used usually include making the connection between the lampshade and the lamp tighter, which means that the elastic margin between the snaps is smaller, causing the block to break more easily.

[0004] It can be seen that the LED linear lights in the prior art still have the problem that when the lamp and the lampshade are connected by buckles, while providing sufficient elastic margin between the buckles for buckle deformation, it is impossible to avoid light leakage and ensure light utilization.

[0023] The double-sided LED linear lamp provided by the present invention, when installing the lampshade, the light-emitting part is pre-embedded into the lamp housing, and then the lampshade is embedded, and finally the inner end cover is slid in the direction close to the lamp housing to complete the installation of the lampshade. During the embedding process of the lampshade, the edge of the card slot can push the card connection part outward, so that the card connection part is inserted into the card slot to complete the installation of the lampshade. At this time, the width of the card slot is greater than the width of the card connection part, which means that the card connection part will be subjected to deformation force only during the insertion process of the card connection part, thereby ensuring the life of the card connection part; then, during the process of the inner end cover pushing the lampshade, the card slot on the lampshade synchronously pushes the card connection part, and then acts on the hook-shaped part, so that The deformation of the hook-shaped portion toward the lamp housing means that the groove wall of the sealing groove also deforms synchronously, so that the lower edge of the lamp housing and the groove wall of the sealing groove can fit tightly, which is equivalent to wrapping the lower edge of the lamp housing, thereby reducing the light leakage of the LED line lamp and thus improving the light utilization rate. It can be understood that for the hook-shaped portion, the force directions in the above two processes are not the same. During the embedding process of the lampshade, the hook-shaped portion expands outward, which is mainly tensile deformation. In the process of the inner end cover pushing the lampshade, the hook-shaped portion deforms toward the lamp housing, which is mainly compressive deformation. The compressive strength of the plastic is greater than the tensile strength, thereby improving the overall life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0038] Example 1

[0039] See also Figures 1 to 10The present invention provides a technical solution: a double-sided LED linear light, comprising a lamp housing 1 with openings at both ends along a first direction, one end opening of the lamp housing 1 being detachably connected to a first light-emitting unit 2, and the other end opening of the lamp housing 1 being installed with a second light-emitting unit 3;

[0040] The second light-emitting unit 3 includes a light-emitting member 31 and a lampshade 32 which are sequentially arranged in a direction away from the other end opening; the light-emitting member 31 includes two hook-shaped portions 311 extending outside the lamp housing 1; a sealing groove 313 is formed on the outer wall surface of the hook-shaped portion 311, and the lower edge of the lamp housing 1 is in contact with the groove wall of the sealing groove 313; the inner wall surface of the hook-shaped portion 311 extends inward to form a clamping portion 312;

[0041] The lampshade 32 includes a slot 325 corresponding to the clamping portion 312, and the width of the slot 325 is greater than the width of the clamping portion 312; L-shaped inner end covers 11 are installed at both ends of the lamp housing 1 along the second direction, and the inner end covers 11 are slidably connected to the lamp housing 1 along the first direction, so that the cover body of the lampshade 32 can move in a direction close to the lamp housing 1 and abut against the clamping portion 312;

[0042] The width of the card slot 325 is greater than the width of the card connection portion 312 , where the width is the length along the first direction;

[0043] The lamp housing 1 is a hollow shell-like structure with openings at both ends along a first direction, serving as a structural frame of the entire lamp for accommodating and supporting light-emitting units, wherein a ventilation unit and a unit for controlling the switch of the lamp may also be provided. The ventilation unit may assist in heat dissipation of the first light-emitting unit 2 and the second light-emitting unit 3, and the switch unit is used to control the opening of the first light-emitting unit 2 and the second light-emitting unit 3. The openings at both ends are designed to facilitate installation and removal of the light-emitting units, facilitate maintenance, and reduce the space occupied by the first light-emitting unit 2 and the second light-emitting unit 3. At the same time, the first light-emitting unit 2 and the second light-emitting unit 3 are stored in the lamp housing 1 without affecting the propagation of light from the first light-emitting unit 2 and the second light-emitting unit 3. At the same time, the first light-emitting unit 2 and the second light-emitting unit 3 may also be protected to prevent users from accidentally touching the ends of the first light-emitting unit 2 and the second light-emitting unit 3, resulting in loose connection or poor contact with the switch unit, and also preventing users from touching the electrical connection part. The fixed end of the first light-emitting unit 2 is detachably connected to one end of the lamp housing 1 along the first direction, providing a light source for one end of the lamp housing 1. The detachable light-emitting unit is convenient for replacement and maintenance, thereby improving the service life and flexibility of the lamp. The light-emitting member 31 and the lampshade 32 provide a light source in another direction, thereby realizing double-sided light emission. Double-sided light emission can improve the comfort brought by the office environment for one person, and avoid the situation that only the work surface is bright while the surrounding is dark, which affects the office mood. Different lampshades 32 can be used to bring different effects to the light. For example, a flat LED lampshade has a wider light distribution, a larger lighting range, and a generally higher overall brightness. The design is simple and easy to clean and maintain. It is suitable for large open office areas that require bright and uniform lighting. Another example is a grille-type LED lampshade, which can better control the light distribution and direction, reduce glare, and reduce reflection. It is suitable for areas that require precise lighting control, such as design studios or drawing rooms, and office areas with many computer screens, which can reduce screen reflection.

[0044] By installing and using the first light-emitting unit 2 and the second light-emitting unit 3 at the same time, when used in an office environment, a certain soothing function is provided, and a more uniform and extensive lighting effect is also provided, which is suitable for places such as shopping malls, offices, and exhibition halls that require large-area lighting, and the inner end cover 11 can also assist in the positioning of the lampshade 32, effectively improving the stability of the engagement, and with the damping generated by the magnet 12, while the inner end cover 11 assists in fixing the lampshade 32, the inner end cover 11 can also be pulled to adjust according to the thickness of the replaced lampshade 32, thereby improving applicability, reducing the use of parts for fixing the inner end cover 11 and the operation steps for adjusting the inner end cover 11, and improving the efficiency of replacement;

[0045] The first light-emitting unit 2 is a light bar, which is a known technology. It is only cited again and no further description is given. The purpose is to cooperate with the second light-emitting unit 3 to realize double-sided light emission.

[0046] The fixed end of the light emitting member 31 is detachably connected to the other end of the lamp housing 1 and covers the opening at the other end of the lamp housing 1 to ensure the structural integrity and beauty. The lampshade 32 is detachably connected to the end of the light emitting member 31 away from the lamp housing 1 to protect the light emitting member 31 and adjust the diffusion of light. The hook portion 311, the clamping portion 312 and the sealing groove 313 are combined into a clamping protrusion. The clamping protrusion is arranged on the light emitting member 31 and protrudes outward, including a hook portion 311 bent inwardly, and a clamping portion 312 is formed at its free end, and a U-shaped block is arranged on the lampshade 32, corresponding to the clamping protrusion. The clamping protrusion and the clamping groove 325 cooperate to achieve a stable connection of the lampshade 32, ensure that the lampshade is not easy to fall off, and is easy to disassemble. The upper edge of the clamping groove 325 passes through the U-shaped block to guide the clamping protrusion (i.e., the hook portion 311) of the lampshade to slide smoothly into the clamping groove In the slot 325, the U-shaped block plays a guiding role during the installation process, making it easier for the buckle protrusion to align with the slot 325, reducing the difficulty of installation and facilitating alignment and engagement during assembly. The hook-shaped portion 311 of the buckle protrusion closely matches the inner wall of the slot 325, providing sufficient mechanical strength to ensure the stability of the lampshade during use. The arrangement of the buckle protrusion and the U-shaped block makes the overall structure of the lamp more compact, without additional protruding parts, reducing the occupied space. At the same time, it also makes the appearance of the lamp more concise and beautiful. The close cooperation between the buckle protrusion and the slot 325 can increase the sealing of the lampshade 32 and prevent dust and moisture from entering the interior of the lamp housing 1. The precise cooperation between the buckle protrusion and the slot 325 and the support of the U-shaped block can effectively reduce the leakage of light from the connection part, thereby improving the light efficiency utilization rate and the lighting effect.

[0047] Through the connection setting between the inner end cover 11 and the magnet 12, the magnet 12 provides an adsorption force, which is convenient for the installation and removal of the inner end cover 11. At the same time, when the inner end cover 11 moves along the first direction, it can generate an adsorption force to assist the inner end cover 11 in positioning, while ensuring that it does not move during operation. The inner end cover 11 is made of metal, such as iron. One end of the inner end cover 11 contacts the surface of the lampshade 32, and the bending part contacts the end faces of the lampshade 32 and the light-emitting component 31, which are used for shading and limiting to prevent light leakage and displacement of the light-emitting component 31. The L-shaped inner end cover 11 not only blocks light, but also plays a limiting role to ensure that the light-emitting component 31 and the lampshade 32 are in the correct position. At the same time, it also plays a protective role to avoid touching the end face of the lampshade 32, causing the lampshade 32 to fall off the light-emitting component 31. The use of the magnet 12 makes the installation and removal of the inner end cover 11 more convenient, reduces the use of parts, and reduces the installation time.

[0048] The magnetic force of the magnet 12 is sufficient to lock the inner end cover 11 and can provide sufficient adsorption force to lock the inner end cover 11 and the lampshade 32, while not affecting the sliding adjustment of the inner end cover 11 along the first direction.

[0049] The specific usage scenario of this embodiment may be on a desk in an office. The lamp housing 1 in this embodiment is installed above the desk surface and is located in front of the user.

[0050] In this embodiment, as a preferred solution, the light emitting member 31 includes a housing 314 and an LED light board 315. The housing 314 is detachably connected to the lamp housing 1 through a quick release mechanism 6. The end surface of the housing 314 is detachably connected to the LED light board 315 through a sliding groove. The hook portion 311 is provided on the housing 314.

[0051] A magnet 12 is disposed between the inner end cover 11 and the inner end surface of the lamp housing 1. The end of one end of the inner end cover 11 is in contact with the surface of the lampshade 32. The bending part of the inner end cover 11 is in contact with the end surfaces of the lampshade 32 and the outer shell 314.

[0052] The quick-release mechanism 6 can be used to quickly remove the housing 314 from the lamp housing 1. The LED light board 315 can be installed or removed through the connection between the LED light board 315 and the housing 314. The slide groove design helps to accurately position the LED light board 315, ensuring its stability in the housing 314, while allowing for removal and replacement without damage, without drilling holes or screwing in screws, thereby reducing the number of operation steps.

[0053] The LED light board 315 is a conventional LED light strip, which is a known technology.

[0054] In this embodiment, as a preferred solution, a support block 322 is protruded at the position of the lampshade 32 corresponding to the clamping portion 312, and a U-shaped block is provided at the end of the support block 322. The sealing portion of the U-shaped block protrudes from the support block 322 to form a clamping groove 325 for the clamping portion 312 to be clamped in. The opening of the U-shaped block is arranged inwardly, and the U-shaped block is composed of two guiding inclined panels 321. The combination of the two guiding inclined panels 321 is arranged in an arc-shaped surface, one of the guiding inclined panels 321 and the lampshade 32 form a clamping groove 325, and the other guiding inclined panel 321 is used to guide the hook-shaped portion 311 to slide into the clamping groove 325;

[0055] The design of the guide inclined panel 321 is helpful for guiding and positioning during the installation process. The arc surface design of the U-shaped block can increase the accuracy and smoothness of the installation. During the assembly process, the snap protrusion of the lamp housing 1 is aligned with the slot 325 of the lamp shade 32. By applying appropriate pressure, the hook portion 311 of the snap protrusion slides along the guide inclined surface until the snap portion 312 is completely embedded in the slot 325. The hook portion 311 of the snap protrusion is in close contact with the inner wall of the slot 325 to form a stable mechanical snap connection to ensure a firm combination between the lamp shade 32 and the lamp housing 1. During disassembly, another guide inclined panel 321 is used to guide the snap portion 312 to slide out of the slot 325. The snap portion 312 is located below the free end of the guide inclined surface. When the snap protrusion slides into the slot 325 and snaps into place, the snap portion 312 can effectively block the reverse movement of the snap protrusion to prevent it from loosening during use.

[0056] In the present embodiment, as a preferred solution, the quick release mechanism 6 includes an insulating pad 61, a rotating shaft 62, a rotating bracket 63, a spring 65, a baffle 66, a locking bolt 67 and two abutment plates 64. A protrusion is provided on the surface of the housing 314, and the end face of the protrusion is slidably connected with the insulating pad 61 through a slide groove provided along the second direction. The inner side wall of the slide groove is provided with a plurality of convex grooves extending along the second direction. The insulating pad 61 is spaced apart from the surface of the housing 314, and the insulating pad 61 is provided with concave grooves matching the convex grooves. Circular through holes are provided on the surfaces of the LED light board 315, the housing 314 and the bottom surface of the insulating pad 61. One end of the rotating shaft 62 passes through the circular holes provided on the LED light board 315, the housing 314 and the insulating pad 61, and is rotatably connected with the LED light board 315, the housing 314 and the insulating pad 61. The other end of the rotating shaft 62 at least partially abuts against the surface of the LED light board 315.

[0057] The cross section of the rotating shaft 62 is waist-shaped. The bottom surface of the rotating bracket 63 and the surface of the baffle 66 are both slidably connected to the surface of the rotating shaft 62 through the waist-shaped hole. The spring 65 is sleeved on the outside of the rotating shaft 62 and one end abuts against the bottom surface of the rotating bracket 63. The other end of the spring 65 abuts against the baffle 66. The end surface of the rotating shaft 62 passing through the baffle 66 is threadedly connected to the locking bolt 67 through the threaded hole, and the locking bolt 67 at least partially abuts against the baffle 66.

[0058] The two abutment plates 64 are respectively fixedly connected to the two ends of the rotating bracket 63, and the inner side wall of the lamp housing 1 is fixedly connected to the two support plates 15, and the two abutment plates 64 are respectively abutted against the upper surfaces of the two support plates 15;

[0059] The insulating pad 61 provides electrical insulation to prevent the rotating bracket 63 from directly contacting the housing 314, avoid short circuit, increase electrical safety, and protect the rotating bracket 63 and the housing 314. The rotating shaft 62 can be quickly disassembled and fixed by rotation. One end of the rotating shaft 62 passes through the circular holes of the LED light board 315, the housing 314, and the insulating pad 61, and is rotatably connected to these components. The other end abuts against the surface of the LED light board 315, which is convenient for installation and disassembly, simplifies operation, and saves time. When the rotating shaft 62 is inserted into the circular holes of the LED light board 315, the housing 314, and the insulating pad 61, the LED light board 315 can be automatically positioned and fixed, without the need for other components to assist in the installation and fixation of the LED light board 315, reducing the operation steps and stably limiting the position of the LED light board 315.

[0060] Through the connection between the rotating bracket 63 and the rotating shaft 62, the rotating shaft 62 can drive the rotating bracket 63 to rotate by rotating. The cross section of the rotating shaft 62 is set in a waist shape, so that it can be slidably connected with the rotating bracket 63 and the blocking piece 66 through the waist-shaped hole. The blocking piece 66 can rotate with the rotating shaft 62. Through the action of the blocking piece 66, the spring 65 is compressed in cooperation with the rotating bracket 63. The force applied by the spring 65 makes the rotating bracket 63 close to the insulating pad 61, thereby increasing the friction between the rotating bracket 63 and the insulating pad 61, and preventing the rotating bracket 63 from rotating easily during the working process, causing the quick release mechanism 6 to loosen and cause the light-emitting component 31 to fall off;

[0061] The rotating bracket 63 rotates with the rotating shaft 62, so that the abutment plate 64 rotates with the rotating bracket 63. The abutment plate 64 rotates to abut against the upper surface of the support plate 15, thereby achieving a quick fixation effect. The support plate 15 presses the abutment plate 64 and does not slide along the first direction to achieve the fixation purpose. The connection between the rotating shaft 62 and the locking bolt 67 is used to limit the blocking piece 66 to prevent the blocking piece 66 from falling off the rotating shaft 62. At the same time, since the blocking piece 66 rotates with the rotating shaft 62, the locking bolt 67 is not easy to loosen, providing additional mechanical locking to prevent loosening due to vibration or external force. The connection is firm and the simplified quick release and fixing mechanism significantly reduces the time required for installation and maintenance, thereby improving work efficiency.

[0062] In this embodiment, as a preferred solution, both ends of the rotating bracket 63 are arranged to be inclined along the first direction, and the two abutment plates 64 are arranged in a V-shape on the upper edges of both ends of the rotating bracket 63, and the V-shaped bottom surfaces of the two abutment plates 64 are respectively in contact with the upper surfaces of the two support plates 15;

[0063] The two ends of the rotating bracket 63 are inclined along the first direction, which can play a compensatory role when rotating. For example, when the rotating bracket 63 rotates, the V-shaped bottom surface of the abutment plate 64 is located at one-third of the rotating bracket 63. When the V-shaped bottom surface of the abutment plate 64 abuts the upper surface of the support plate 15, the side surface of the support plate 15 and the side surface of the rotating bracket 63 are spaced apart. If it is a straight edge, the side surface of the rotating bracket 63 may contact the side surface of the support plate 15 in advance, thereby forming interference, resulting in failure to rotate normally to achieve locking and limiting. At the same time, when the V-shaped bottom surface of the abutment plate 64 is too low, the two ends of the rotating bracket 63 The ends can be moved toward the middle for compensation, thereby improving the adaptability of the structure and avoiding the inability of hard connection to compensate, resulting in the inability to make the V-shaped bottom surface of the abutment plate 64 abut against the upper surface of the support plate 15. The V-shaped structure of the abutment plate 64 helps to evenly distribute the force of the rotating bracket 63 to the support plate 15, thereby increasing the stability and carrying capacity of the system. The V-shaped structure makes the contact between the abutment plate 64 and the support plate 15 closer, thereby improving the stability of the connection. At the same time, the side of the V-shaped structure can play a guiding role during rotation, thereby increasing the accuracy and smoothness of the installation, increasing the overall rigidity of the system, and improving the vibration and impact resistance.

[0064] In this embodiment, as a preferred solution, there are two quick release mechanisms 6, which are symmetrically arranged on the housing 314, and the abutment plate 64 and the rotating bracket 63 are both made of conductive metal. The upper surfaces of the two support plates 15 are respectively provided with a first contact 16 and a second contact 17, and the two abutment plates 64 on one quick release mechanism 6 correspond to the first contact 16 and the second contact 17, so that the first contact 16 and the second contact 17 are connected;

[0065] When one of the quick release mechanisms 6 is rotated and locked, the two abutment plates 64 cause the first contact 16 to be connected with the second contact 17. When the quick release mechanism 6 is rotated and released, the electrical connection between the first contact 16 and the second contact 17 is disconnected.

[0066] In this embodiment, as a preferred solution, one end of the lamp housing 1 is detachably connected to the control component 4, and the control component 4 covers the opening at one end of the lamp housing 1, and an electromagnet 41 is provided on the control component 4, and the first contact 16 and the second contact 17 are connected in series in the circuit of the electromagnet 41, and the fixed end of the first light-emitting unit 2 is made of magnetic material, and the fixed end of the first light-emitting unit 2 is detachably connected to the surface of the control component 4 through the electromagnet 41;

[0067] When one of the quick release mechanisms 6 is rotated and locked, the two abutment plates 64 cause the first contact 16 to communicate with the second contact 17, so that the electromagnet 41 is energized and magnetized, so that the first light-emitting unit 2 can be installed, but it is not a locked installation, and the first light-emitting unit 2 can still be disassembled. The magnetic force can play an auxiliary fixing role. When the quick release mechanism 6 is rotated and released, the first contact 16 and the second contact 17 are electrically disconnected, so that the electromagnet 41 is powered off and demagnetized, making it impossible to install the first light-emitting unit 2;

[0068] The purpose is that the first light-emitting unit 2 is installed at the right time. When the first light-emitting unit 2 is not needed, it can be chosen not to be installed. The second light-emitting unit 3 is the main light source. When the first light-emitting unit 2 is needed, the first light-emitting unit 2 is installed to cooperate with the second light-emitting unit 3.

[0069] Specifically, the fixed end of the first light-emitting unit 2 is an iron bar, which can be preset for the first light-emitting unit 2 or added to the first light-emitting unit 2. The purpose is to improve the compatibility of the lamp housing 1 and the first light-emitting unit 2, so that first light-emitting units 2 of different sizes can be installed on the lamp housing 1 without opening corresponding threaded holes, thereby avoiding the threaded holes opened on the first light-emitting unit 2 and the threaded holes opened on the lamp housing 1 from being incompatible.

[0070] In this embodiment, as a preferred solution, the control component 4 includes a mounting plate 42, a power supply 43 and a control module 44. One end of the lamp housing 1 is sleeved on the outer surface of the mounting plate 42 through an opened groove. The electromagnet 41 is fixedly connected to the surface of the mounting plate 42. The electromagnet 41 is electrically connected to the power supply 43. The first contact 16 and the second contact 17 are connected in series with the connection between the electromagnet 41 and the power supply 43. The control module 44 is electrically connected to the power supply 43. The input end of the light-emitting end of the first light-emitting unit 2 and the input end of the LED lamp board 315 are both electrically connected to the output end of the control module 44.

[0071] The power supply 43 and the control module 44 are existing well-known technologies and are only cited here. The power supply 43 has a built-in battery and is provided with a charging end and an output end. The built-in battery of the power supply 43 is charged through the charging end and outputs at the same time, and can also have a certain capacity to power the power magnet 41 when not charging.

[0072] In this embodiment, as a preferred solution, an insert block 45 is provided at the bottom of the mounting plate 42, and a locking hole 46 that cooperates with the insert block 45 is provided on the surface of the blocking piece 66. Through the cooperation between the insert block 45 and the locking hole 46, when the second light-emitting unit 3 is installed, the rotation of the rotating shaft 62 can be directly locked. Specifically, after the rotating shaft 62 is connected to the gasket, the shell 314 is inserted into the lamp housing 1, and the mounting plate 42 is placed at the other end of the lamp housing 1, so that the insert block 45 is inserted into the locking hole 46. When the shell 314 is fixed to the lamp housing 1 by rotating the rotating shaft 62, the mounting plate 42 is locked at the same time. At the same time, through the rotation of the rotating shaft 62, the two abutment plates 64 on one of the rotating brackets 63 cause the first contact 16 to be connected with the second contact 17, and the electromagnet 41 is energized and magnetized, so that the first light-emitting unit 2 can be installed.

[0073] Integration can reduce the use of parts, effectively improve the efficiency of installation and disassembly, reduce costs and facilitate use.

[0074] Example 2

[0075] According to the above embodiment, please refer to Fig.11 and Fig.12 The present invention provides a second embodiment, the lampshade 32 includes a grille plate 323 and a light-collecting shell 324, the surface of the grille plate 323 is provided with an avoidance opening, one end of the light-collecting shell 324 is fixedly connected to the surface of the grille plate 323 and is located in the shell 314, the opening diameter of one end of the light-collecting shell 324 located in the shell 314 is smaller than the opening diameter of one end shielding the avoidance opening, the side surface of the grille plate 323 is slidably connected to one end of the shell 314 along the first direction, the lamp beads arranged on the LED lamp board 315 correspond to the light-collecting shell 324, one end of the light-collecting shell 324 located in the shell 314 opens to the outside of the lamp beads, and the surface of the grille plate 323 is provided with an operation opening corresponding to the rotating shaft 62;

[0076] The grille plate 323 is composed of a plurality of openings to form a grid structure, which can better control the light distribution and direction, reduce glare, and reduce reflection by cooperating with the focusing shell 324. It is specifically applied to office desks and design tables to prevent glare from affecting users. At the same time, through the function of the focusing shell 324, light will not leak out through the operation port, thus avoiding light leakage. At the same time, the operation port can be inserted into the operation port to rotate the rotating shaft 62, so as to realize rapid disassembly of the outer shell 314, avoiding the steps of first disassembling the lampshade 32 and then disassembling the outer shell 314. In the above embodiment, the inner end cover 11 needs to be lowered along the first direction first, and then the lampshade 32 is disassembled. After another lampshade 32 is clamped on the outer shell 314, the inner end cover 11 is raised, so that one end of the inner end cover 11 is against the surface of the replaced lampshade 32.

[0077] At the same time, through the connection between the grille plate 323 and the shell 314, the grille plate 323 and the shell 314 are not snap-fitted, but are directly plugged in. The surfaces opposite to the grille plate 323 and the shell 314 are both arranged with end slopes. After the direct plug-in connection, it is an interference connection. There is a certain friction between the grille plate 323 and the shell 314 to prevent the grille plate 323 from detaching from the shell 314. At the same time, one end of the inner end cover 11 is in contact with the grille plate 323, which can play an auxiliary fixing role to prevent the grille plate 323 from accidentally falling off during operation. When the inner end cover 11 rises with the grille plate 323 The grille plate 323 can be directly fixed on the outer shell 314, which improves the efficiency of installation and reduces the steps of installation. The grille plate 323 is fixed by the inner end cover 11 and the magnet 12. The length of the grille plate 323 is suitable for the clamping force of the two inner end covers 11 to ensure that the grille plate 323 does not fall during operation. Moreover, through the action of the magnet 12, it can be used for a long time to avoid the service life of other damping parts being affected by wear and tear, and ensure that the grille plate 323 is clamped and fixed for a long time. When it falls, it can be reset by pushing it. The magnet 12 can also be replaced, which is convenient, efficient and has low maintenance cost.
