Description

Technical Field

[0001] This utility model belongs to the field of lamp technology, specifically relating to an LED optical linear light with adjustable illumination direction. Background Technology

[0002] LED tubes, as a common lighting fixture structure, are widely used in various lighting scenarios. When in use, LED tubes need to be combined with LED tube holders. Existing technologies typically include LED tubes and holders comprising a support plate, a first positioning seat, and a second positioning seat. During use, both ends of the tube are positioned on the first and second positioning seats via auxiliary positioning mechanisms, as shown in CN202220912365.1, which describes an LED tube adapter for a fluorescent tube holder. While this can meet general usage requirements, in practical applications, the tube's position is relatively fixed after assembly. After installing the light source board, there is a certain blind spot behind the substrate. Because the illumination angle cannot be adjusted as needed, the installation requirements for the tube holder are high, greatly increasing the difficulty of installation. Furthermore, the illumination direction cannot be adjusted after installation, which also affects its applicability. Summary of the Invention

[0003] The purpose of this invention is to provide an LED optical linear light with adjustable illumination direction, aiming to solve the technical shortcomings of the prior art where the illumination angle cannot be adjusted.

[0004] The technical solution to achieve the purpose of this utility model is an LED optical linear light with adjustable illumination direction, including a lamp holder and a lamp tube. The lamp holder includes a support plate and a first end cover and a second end cover fixed at both ends of the support plate. The lamp tube includes a substrate with an arc-shaped cross section, a light source plate fixed on the plane of the substrate, and a lens cover disposed at the plane opening of the substrate. The substrate is fixed with connecting face covers at both ends. The outer side of the connecting face cover is integrally formed with screw holes and conductive holes in the middle. The outer side of the connecting face cover is integrally formed with a semi-circular convex edge. The upper part of the support plate is provided with a driving power supply, and the bottom surface of the support plate is provided with an arched clearance recess area. The connecting covers at both ends of the substrate are rotatably connected to the first end cover and the second end cover respectively by screws, and the lamp tube rotates around the screw in the lamp holder. The first end cover or the second end cover is provided with a power connector that can be connected in series, and the wires of the light source board are always electrically connected to the output terminal of the driving power supply when the lamp tube rotates.

[0005] A further preferred embodiment is that a limiting protrusion is integrally formed on the inner wall of the first end cap or the second end cap; Both ends of the semi-circular convex edge are integrally formed with limiting blocks that bend towards the center; The limiting protrusion is disposed close to the inner ring surface of the semi-circular convex edge, and when the lamp tube rotates on the lamp holder, the limiting protrusion moves on the inner ring edge of the semi-circular convex edge and is limited by the limiting stop.

[0006] A further preferred embodiment is that the inner surfaces of the first end cap and the second end cap are evenly provided with a plurality of radial grooves centered on the screw. A ball is fixed to the outer side of the connecting cover. The ball is positioned within one of the radial grooves and is limited in place. When the lamp tube rotates, the ball bounces in the adjacent radial grooves and produces a prompting sound.

[0007] A further preferred embodiment is that the outer wall of the symmetrical edge of the substrate is provided with a strip-shaped groove; The symmetrical top edges of the lens cover are all fixed with fasteners; The lens cover is positioned by a latch within the strip groove of the substrate.

[0008] A further preferred embodiment is that the lens cover is an arc-shaped cover or a planar cover.

[0009] A further preferred embodiment is that both the support plate and the substrate are aluminum structural components.

[0010] A further preferred embodiment includes an n-shaped mounting plate for fixing to the mounting surface; The upper part of the symmetrical outer wall of the lamp holder is provided with a strip-shaped groove; The lamp holder is inserted into the n-shaped mounting plate, and both ends of the n-shaped mounting plate are respectively inserted into the strip groove for positioning.

[0011] Compared with the prior art, the present invention has the following positive effects: the connecting covers at both ends of the substrate of the present invention are rotatably connected to the first end cover and the second end cover respectively by screws, and the lamp tube rotates around the screw in the lamp holder; therefore, when the lamp tube is installed on the lamp holder, the position of the lamp tube on the lamp holder can be rotated as needed, so that the lens cover can irradiate in different directions to meet the irradiation needs of different directions, reduce the installation requirements of the lamp holder, improve the convenience of installation, and solve the technical deficiency of the prior art that the irradiation angle cannot be adjusted; Furthermore, a limiting protrusion is integrally formed on the inner wall of the first end cover or the second end cover; the two ends of the semi-circular protrusion are integrally formed with limiting blocks bent towards the center. When rotating, the limiting blocks can be used in conjunction with the limiting protrusions to limit the rotation, that is, it can only rotate within a 180-degree range, which can prevent damage to the wires of the light source board during the rotation. Moreover, several radial grooves centered on the screw are evenly arranged on the inner surfaces of the first end cover and the second end cover. Furthermore, a ball is fixed on the outer side of the connecting cover. The ball is positioned within one of the radial grooves and is limited. When the lamp rotates, the ball bounces in the adjacent radial grooves and makes a sound. Not only can the rotation angle be limited by the ball, but it also makes a sound when rotating, which makes it easier for the operator to judge and also improves the feel. It is highly applicable.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an adjustable illumination direction LED optical linear light includes a lamp holder 1 and a lamp tube 2. The lamp holder includes a support plate 1-1 and a first end cover 1-2 and a second end cover 1-3 fixed at both ends of the support plate. The support plate is an aluminum structural component, and the first end cover and the second end cover are both plastic structural components. The length of the support plate can be processed and set as needed, and a cavity can be set inside the support plate. The first end cover, the second end cover and the support plate can be fixed with screws or with snaps, which is a conventional application of the prior art, so it is not described in detail. In this embodiment, the lamp tube includes a substrate 21 with an arc-shaped cross-section, a light source plate 22 fixed on the plane of the substrate, and a lens cover 23 disposed at the plane opening of the substrate; the substrate is an aluminum structural component. The light source board and lens cover are conventional structures of existing technology, and are simply applied, so they are not described in detail. The length of the substrate matches the length of the support plate. At the same time, the two ends of the substrate are fixed with connecting cover 24. The outer side of the connecting cover has a screw hole post 3 and a conductive hole 4 integrally formed in the middle. The outer side edge of the connecting cover has a semi-circular protrusion 5 integrally formed. In this embodiment, the connecting cover and the substrate are fixed with screws or buckles, which is a conventional structure of existing technology and is simply applied, so it is not described in detail. The screw hole post is located in the center of the connecting cover, and the connecting cover is a circular cover. The conductive hole is mainly for the passage of wires, and the wires can be spiral wires, which can be buffered within a certain range during rotation to prevent damage to the wires. The semi-circular protrusion is mainly used for rotation guidance, and its outer surface is attached to the bottom edge of the first end cover or the second end cover to prevent displacement or misalignment. Furthermore, the upper part of the support plate is provided with a driving power supply 1-4, and the bottom surface of the support plate is provided with an arched recessed area 6. The arched recessed area cooperates with the arc-shaped base plate to ensure smooth rotation of the base plate within it and prevent the sticking from affecting the rotation. During assembly, the connecting face covers at both ends of the base plate are rotatably connected to the first end cover and the second end cover respectively by screws, and the lamp tube rotates around the screw in the lamp holder. The first end cover or the second end cover is provided with a power connector 13 that can be connected in series. The power connector is connected to the driving power supply in the support plate through wires. The output line of the driving power supply is soldered to the light source board after passing through the conductive holes on the first end cover and the connecting face cover. The wires of the light source board are always electrically connected to the output end of the driving power supply when the lamp tube rotates. Adjacent lamp holders can be connected in series through the power connector.

[0016] like Figure 2 and Figure 4As shown, in this embodiment, a limiting protrusion 7 is integrally formed on the inner wall of the first end cap or the second end cap; and limiting blocks 8 bent towards the center are integrally formed at both ends of the semi-circular convex edge. In actual application, the limiting protrusion can be set on the first end cap or the second end cap, or both can be provided with limiting protrusions. During assembly, the limiting protrusion is set close to the inner ring surface of the semi-circular convex edge, and when the lamp tube rotates on the lamp holder, the limiting protrusion moves on the inner ring edge of the semi-circular convex edge and is limited by the limiting blocks. That is, the rotation angle is limited to prevent excessive rotation. With the vertical position of the light source board as the reference point, it can achieve a 90-degree rotation operation to both sides, and can achieve an angle adjustment operation within a range of 180 degrees. like Figure 3 As shown in this embodiment, the inner surfaces of the first and second end caps are uniformly provided with a plurality of radial grooves 9 centered on the screw; a ball bearing 10 is fixed to the outer surface of the connecting cover. The ball bearing is positioned within one of the radial grooves and is limited in place. When the lamp tube rotates, the ball bearing bounces in adjacent radial grooves and produces a warning sound. The ball bearing is a conventional structure of the prior art, simply applied. It includes a cylindrical column, a spring-loaded steel ball, and the spring and steel ball are located inside the cylindrical column. A limiting ring is provided at the opening of the cylindrical column. The outer side of the steel ball can extend out of the limiting ring under the action of the spring and is engaged in the radial groove during rotation. In actual application, the radial grooves and limiting protrusions can be set on the same first or second end cap, or they can be set on different first and second end caps respectively, and can be processed and set as needed.

[0017] In this embodiment, the outer wall of the symmetrical edge of the substrate is provided with a strip-shaped groove 11; the symmetrical top edges of the lens cover are each fixed with a fastener 12; during assembly, the fasteners of the lens cover are positioned within the strip-shaped groove of the substrate. The lens cover is an arc-shaped cover or a planar cover. This improves the ease and effectiveness of lens cover installation.

[0018] It is also provided with an n-shaped mounting piece 14 for fixing on the mounting surface; a strip groove 15 is provided on the upper part of the symmetrical outer wall of the lamp holder; the lamp holder is inserted into the n-shaped mounting piece, and the two ends of the n-shaped mounting piece are respectively inserted into the strip groove for limiting.

[0019] Compared with the prior art, the present invention has the following positive effects: the connecting covers at both ends of the substrate of the present invention are rotatably connected to the first end cover and the second end cover respectively by screws, and the lamp tube rotates around the screw in the lamp holder; therefore, when the lamp tube is installed on the lamp holder, the position of the lamp tube on the lamp holder can be rotated as needed, so that the lens cover can irradiate in different directions to meet the irradiation needs of different directions, reduce the installation requirements of the lamp holder, improve the convenience of installation, and solve the technical deficiency of the prior art that the irradiation angle cannot be adjusted; Furthermore, a limiting protrusion is integrally formed on the inner wall of the first end cover or the second end cover; the two ends of the semi-circular protrusion are integrally formed with limiting blocks bent towards the center. When rotating, the limiting blocks can be used in conjunction with the limiting protrusions to limit the rotation, that is, it can only rotate within a 180-degree range, which can prevent damage to the wires of the light source board during the rotation. Moreover, several radial grooves centered on the screw are evenly arranged on the inner surfaces of the first end cover and the second end cover. Furthermore, a ball is fixed on the outer side of the connecting cover. The ball is positioned within one of the radial grooves and is limited. When the lamp rotates, the ball bounces in the adjacent radial grooves and makes a sound. Not only can the rotation angle be limited by the ball, but it also makes a sound when rotating, which makes it easier for the operator to judge and also improves the feel. It is highly applicable.

[0020] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0021] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
