[0002] Downlights and similar lighting fixtures are often used in indoor spaces, exhibitions, restaurants, libraries, exhibition halls, and other venues to create lighting atmospheres.

[0003] The downlight is attached to a wall, ceiling, or display stand via a boom that has wiring channels for the wires to pass through and connect to the light source. The lower end of the boom is hinged to the top cover of the downlight, allowing the downlight to swing relative to the boom to adjust the lighting angle.

[0004] When the downlight is adjusted, it forms an angle with the boom, which causes the wire passing through that point to bend. The existing boom does not have a avoidance structure at the connection point, and the bent wire will rub against the inner wall of the wiring channel. After repeated bending, the wire is prone to wear and short circuit defects. Utility Model Content

[0008] The end of the connecting column that connects to the connecting cylinder has a spherical connecting end, which is pivotally mounted in the connecting cylinder. The cylinder wall of the connecting cylinder is provided with a notch for accommodating the swinging connecting column.

[0009] The spherical connector end is provided with a relief groove for avoiding bending wires, and the relief groove is located around the channel opening of the wiring channel.

[0010] In one of the alternative technical solutions, when the axis of the lamp tube coincides with the axis of the connecting post, the clearance groove is housed in the connecting tube;

[0011] When a non-zero angle is formed between the axis of the lamp tube and the axis of the connecting column, a portion of the clearance groove is exposed outside the connecting tube.

[0012] In one of the alternative technical solutions, the avoidance groove includes a straight groove in the shape of a straight line, which is aligned with the notch in the cylinder wall.

[0013] In one of the alternative technical solutions, the avoidance groove includes two straight grooves arranged intersectingly, wherein one of the straight grooves is aligned with the notch in the cylinder wall.

[0014] In one of the alternative technical solutions, the connecting cylinder is provided with a limiting structure for preventing the spherical connecting end from disengaging from the opening of the connecting cylinder.

[0015] In one of the alternative technical solutions, the limiting structure includes a flange disposed on the inner surface of the cylinder opening.

[0016] In one of the alternative technical solutions, the end of the radiator facing the connecting post is provided with a radiator recess for accommodating the spherical connecting end.

[0017] In one of the alternative technical solutions, a sealing ring is provided between the heat sink and the lamp tube, and the lamp tube is fixed to the heat sink through the sealing ring.

[0018] In one of the alternative technical solutions, the lamp barrel includes a lamp barrel body and a lens assembly snapped into the lamp barrel body;

[0019] The other end of the heat sink extends into the lamp body, and the light source faces the lens assembly;

[0042] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0043] like Figure 1-10 As shown, an embodiment of the present invention provides a lamp body, including a connecting post 1 with a wiring channel 12, a lamp tube 2 with a light source 23, a connecting tube 3 assembled between the connecting post 1 and the lamp tube 2, and a heat sink 4 with a wiring through hole 41.

[0044] One end of the radiator 4 is connected to the connecting cylinder 3, and the other end of the radiator 4 extends into the lamp tube 2. The light source 23 is connected to the other end of the radiator 4.

[0045] The end of the connecting column 1 that connects to the connecting cylinder 3 has a spherical connecting end 11, which can be pivotally mounted in the connecting cylinder 3. The cylinder wall of the connecting cylinder 3 is provided with a cylinder wall notch 31 for accommodating the swinging connecting column 1.

[0046] The spherical connector 11 is provided with a relief groove 111 for avoiding bending of the wire harness. The relief groove 111 is located around the channel opening 121 of the wiring channel 12.

[0047] The lamp body provided by this utility model includes a connecting post 1, a lamp tube 2, a connecting tube 3, and a heat sink 4.

[0048] The connecting column 1, also known as the boom, is used to install the lamp body in a designated location, such as hanging it under the ceiling, installing it on the wall, or installing it on a display stand.

[0049] The connecting post 1 has a wiring channel 12 that runs along the axial direction for laying wire harnesses, for example, wire harnesses for connection with the light source 23, which then pass through to connect with external wires.

[0050] The lamp holder 2 is equipped with a light source 23, which is preferably an LED light source, such as an LED bulb.

[0051] The connecting cylinder 3 is assembled between the connecting post 1 and the lamp tube 2. The lower end of the connecting post 1 is connected to the connecting cylinder 3.

[0052] Lamp tube 2 has two assembly methods:

[0053] Method 1: The upper end of the lamp tube 2 is connected to the lower end of the connecting tube 3, for example, by means of threads, clips, pins, etc.

[0054] Method 2: The lamp tube 2 is fastened to the heat sink 4. The upper end of the lamp tube 2 is not connected to the lower end of the connecting tube 3. The two are in close contact or a preset gap is left.

[0055] The upper end of the heat sink 4 is connected to the connecting cylinder 3, for example, via a threaded connection. The lower end of the heat sink 4 extends into the lamp tube 2, and the light source 23 is located on the bottom surface of the heat sink 4. The heat sink 4 has a through-hole 41 for the wiring harness connected to the light source 23 to pass through, and then exit through the wiring channel 12. The through-hole 41 and the wiring channel 12 also serve a certain function of ventilation and heat dissipation. The heat generated by the light source 23 is mainly dissipated by the heat sink 4.

[0056] The material of the connecting cylinder 3 can be selected as needed; for example, plastic or metal parts can be selected.

[0057] The lower end of the connecting column 1 has a spherical connecting end 11, which is pivotally mounted in the connecting cylinder 3.

[0058] To allow the lamp tube 2 to swing and adjust towards one or more sides of the connecting column 1, a notch 31 is provided on the wall of the connecting cylinder 3. The notch 31 is located around the top opening of the connecting cylinder 3. When the lamp tube 2 swings to one side to adjust its angle, the connecting cylinder 3 swings as a whole, and the connecting column 1 can lie horizontally in and pass through the notch 31. This allows the lamp tube 2 to swing approximately 90° relative to the connecting column 1, adjusting from vertical downward illumination to horizontal illumination, thus increasing the adjustment range of the lamp tube 2. If the notch 31 is not provided on the wall, the lamp tube 2 will be blocked by the top surface of the wall after swinging a certain angle, and the swing angle of the lamp tube 2 relative to the connecting column 1 will be less than 90°.

[0059] A clearance groove 111 is provided in the lower middle part of the spherical connection end 11. The clearance groove 111 is located around the channel opening 121 of the wiring channel 12 and is used to avoid bending of the wire harness. When the lamp 2 swings to adjust the angle, the wire harness can bend at the clearance groove 111. The clearance groove 111 provides clearance space for the bent wire harness, avoiding friction between the bent wire harness and the wall of the wiring channel 12, overcoming the defects of the prior art and extending the service life of the product. The clearance groove 111 can also limit the bending part of the wire harness, preventing it from shaking out of position, so that the wire harness is kept on the path between the wiring through hole 41 and the wiring channel 12, so that when the lamp 2 is reset, the two ends of the bent wire harness can smoothly return to the wiring through hole 41 and the wiring channel 12 respectively.

[0060] When the lamp tube 2 swings about 90°, the wire harness located between the channel opening 121 and the upper opening of the wiring through hole 41 also bends about 90°. Since the clearance groove 111 is provided, this part of the wire harness can be accommodated and the wire harness can be limited to prevent it from shaking out of position, so that the wire harness remains on the original path so that when the lamp tube 2 is reset, the wire harness is reset accordingly.

[0061] In one embodiment, such as Figure 1-3 As shown, when the axis of the lamp tube 2 coincides with the axis of the connecting column 1, the clearance groove 111 is housed in the connecting tube 3.

[0062] When a non-zero angle is formed between the axis of lamp tube 2 and the axis of connecting column 1, part of the clearance groove 111 is exposed outside the connecting tube 3.

[0063] With this configuration, as long as the lamp tube 2 swings relative to the connecting post 1, a portion of the clearance groove 111 will be exposed from the top opening of the connecting tube 3, and the bent wire harness will not rub against the tube wall of the connecting tube 3.

[0064] In normal conditions, the lamp tube 2 is vertically downward. At this time, the top edge of the side opening of the clearance groove 111 is slightly lower than the top edge of the top through hole of the connecting tube 3, so the clearance groove 111 is housed in the connecting tube 3. Of course, a part of the clearance groove 111 can be seen from the side of the tube wall notch 31.

[0065] When the lamp tube 2 is swung, the connecting tube 3 also swings. The top edge of the side opening of the clearance groove 111 will be higher than the top edge of the top through hole of the connecting tube 3, so a part of the clearance groove 111 will be exposed from the top opening of the connecting tube 3.

[0066] In one embodiment, such as Figure 1-5 and Figure 7-8As shown, the clearance groove 111 includes a straight groove 111a, which is aligned with the notch 31 in the cylinder wall. That is, one side of the straight groove 111a faces the notch 31 in the cylinder wall, and the other side faces away from the notch 31. When the connecting post 1 lies in the notch 31 in the cylinder wall, the bent wire harness will be exposed from the other side opening of the straight groove 111a. The straight groove 111a can better prevent the wire harness from swaying left and right.

[0067] In one embodiment, such as Figure 1-8 As shown, the clearance groove 111 includes two straight grooves 111a, which are arranged in a cross pattern. One of the straight grooves 111a is aligned with the notch 31 in the cylinder wall, providing more options. The direction of the connecting column 1 can be adjusted so that different straight grooves 111a are aligned with the notch 31 in the cylinder wall.

[0068] In this embodiment, the clearance groove 111 is cross-shaped and includes two straight grooves 111a. The two straight grooves 111a are arranged in a cross pattern, thereby dividing the lower half of the spherical connecting end 11 into four arc-shaped claws 112. When squeezed, the arc-shaped claws 112 can deform so that the spherical connecting end 11 can be squeezed into the top opening of the connecting cylinder 3. After the spherical connecting end 11 is squeezed into the connecting cylinder 3, the arc-shaped claws 112 are reset.

[0069] In one embodiment, the connecting cylinder 3 is provided with a limiting structure for preventing the spherical connecting end 11 from disengaging from the opening of the connecting cylinder 3. The limiting structure may be a limiting pin, a limiting shaft, a limiting protrusion, or the like.

[0070] In one embodiment, such as Figure 5-6 and Figure 9 As shown, the limiting structure includes a flange 32 on the inner surface of the cylinder opening. The flange 32 forms a circle, and its radius is slightly smaller than the maximum diameter of the spherical connecting end 11. The spherical connecting end 11 can be squeezed into the cylinder opening formed by the flange 32, or the connecting post 1 can be inserted from the other end of the cylinder opening, so that the connecting post 1 protrudes from the cylinder opening formed by the flange 32, with the spherical connecting end 11 located below the flange 32.

[0071] In one embodiment, such as Figure 5-6 and Figure 10 As shown, the end of the radiator 4 facing the connecting post 1 is provided with a radiator recess 42 for accommodating the lower end of the spherical connecting end 11. The radiator recess 42 is used to place the lower part of the spherical connecting end 11. When the axis of the lamp tube 2 coincides with that of the connecting post 1, the radiator recess 42 plays a role in stabilizing the spherical connecting end 11.

[0072] Specifically, the radiator recess 42 is used to house most of the arc-shaped claw 112.

[0073] In one embodiment, such as Figure 4-6 As shown, a sealing ring 5 is provided between the heat sink 4 and the lamp tube 2, and the lamp tube 2 is fixed to the heat sink 4 through the sealing ring 5.

[0074] In this embodiment, a sealing ring 5 is provided between the heat sink 4 and the lamp tube 2, serving a sealing and assembly function. A groove 43 is provided on the outer circumferential surface of the lower end of the heat sink 4. The sealing ring 5 is fitted into the groove 43, protruding from the groove 43 and pressing against the inner surface of the lamp tube 2 to provide friction, thereby assembling the lamp tube 2 onto the heat sink 4. Multiple sealing rings 5 ​​can be provided as needed.

[0075] In one embodiment, such as Figure 4-6 and Figure 11 As shown, the lamp tube 2 includes a lamp tube body 21 and a lens assembly 22 that is snapped into the lamp tube body 21.

[0076] The other end of the heat sink 4 extends into the lamp body 21, and the light source 23 faces the lens assembly 22.

[0077] The lens assembly 22 includes a lens mount 221, an optical lens 222, and a protective lens 223.

[0078] The lens mount 221 has a lens mounting groove 221b and a lens slot 221a. The protective lens 223 is placed in the lens mounting groove 221b, and the optical lens 222 is held in the lens slot 221a.

[0079] The lens mount 221 is located in the lamp body 21 and is engaged with the wall of the lamp body 21.

[0080] In this embodiment, the lamp barrel 2 includes a lamp barrel body 21 and a lens assembly 22. The lower end of the heat sink 4 extends into the lamp barrel body 21. The lens assembly 22 is snapped into the lamp barrel body 21, and the light source 23 faces the lens assembly 22.

[0081] The lens assembly 22 includes a lens mount 221, an optical lens 222, and a protective lens 223.

[0082] The lens mount 221 has a lens mounting groove 221b and a lens retaining slot 221a. The radius of the lens mounting groove 221b is smaller than the radius of the lens retaining slot 221a, and the lens retaining slot 221a is positioned above the lens mounting groove 221b. A protective lens 223 is placed in the lens mounting groove 221b, and an optical lens 222 is held in place in the lens retaining slot 221a, with its lower end pressing down on the protective lens 223. The protective lens 223 serves as a dustproof element. The optical lens 222 is preferably a convex lens, serving as a light-focusing element.

[0083] The lens mount 221 is located within the lamp body 21 and engages with the wall of the lamp body 21. Specifically, several claws 221c can be provided on the outer circumferential surface of the lens mount 221, and a groove 211 is provided on the inner surface of the lamp body 21, in which the claws 221c engage. The lens mount 221 can be rotated as needed to adjust the focusing direction.

[0084] Preferably, the lens slot 221a has several notches 221d in the slot wall, which facilitates the deformation of the slot wall when subjected to force, so as to squeeze the lens holder 221 into the lamp body 21 and realize the engagement of the claw 221c with the slot 211.

[0085] like Figure 12-13 As shown, a lamp provided in one embodiment of the present invention includes a connecting base 6 and a lamp body as described in any of the preceding embodiments, wherein the connecting base 6 is connected to the connecting post 1.

[0086] The connector 6 can be a ceiling mount, a guide rail mount, etc. If necessary, the connector 6 can be equipped with elastic claws 7 so that the connector 6 can be hung on the ceiling, ceiling, or display rack.

[0087] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0088] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
