Description

Technical Field

[0001] This utility model relates to LED lighting fixtures, specifically disclosing an adjustable telescopic spotlight. Background Technology

[0002] refer to Figure 7 Existing spotlights include a lamp barrel 01 and a lamp holder 02. The lamp barrel 01 houses optical components such as a light source, lens, and reflector. The lamp holder 02 is used to mount the lamp barrel 02. A connecting rod 021 is provided at the lower end of the lamp holder 02. A notch 011 extending to the top of the lamp barrel 01's outer shell is provided at the upper end. A fixed shaft 012 is provided within the notch 011. The connecting rod 021 is rotatably hinged to the fixed shaft 012 through the notch 011. This allows the lamp barrel 01 to rotate around the fixed shaft 012 to adjust the light emission angle. To avoid interference between the lamp barrel 01 and the lower end of the lamp holder 02 during rotation, a large gap must be maintained between the upper end of the lamp barrel 01 and the lower end of the lamp holder 02. Therefore, existing spotlights suffer from drawbacks such as large gaps between moving parts, long spotlight length, poor overall luminaire integrity, and poor aesthetics. Furthermore, the connecting rod 021 is completely exposed within the mounting notch 011, which also affects the overall integrity and aesthetics of the luminaire. Utility Model Content

[0003] Therefore, it is necessary to provide an adjustable telescopic spotlight that can conceal the gaps between moving parts, and has good overall integrity and aesthetics, in order to address the problems of existing technologies.

[0004] To address the problems of existing technologies, this utility model discloses an adjustable-angle telescopic spotlight, comprising a lamp tube, a lamp holder, a mounting ring, and a storage tube. The upper end of the side wall of the lamp tube has a notch extending to the top, and a fixed shaft is disposed within the notch. The lower end of the lamp holder has a connecting part, which is hinged to the fixed shaft through the notch. The lamp holder is slidably mounted inside the storage tube. The mounting ring receives the outside of the opening of the storage tube, and a flange is provided at the lower end of the mounting ring. Elastic pressure plates are provided on both sides of the mounting ring. The connecting part is located on one side of the lower end face of the lamp holder. When the lamp holder slides to the lower stop point of the opening of the storage tube, its lower end face is located inside the mounting ring. The side wall of the mounting ring blocks the gap between the upper end face of the lamp tube and the lower end face of the lamp holder.

[0005] The beneficial effects of this utility model are as follows: When the lamp holder slides to the lower stop point of the storage tube opening, its lower end face is located inside the mounting ring, and the side wall of the mounting ring blocks the gap between the upper end face of the lamp tube and the lower end face of the lamp holder, which can improve the overall integrity and aesthetics of the lamp. Furthermore, since the connecting part is set on one side of the lower end face of the lamp holder, the rotation radius of the interference part of the lamp tube can be reduced, thereby reducing the anti-interference gap between the lamp tube and the lamp holder and reducing the overall length of the lamp.

[0006] As a further improvement to this utility model, a baffle plate flush with the outer side of the lamp tube and capable of covering the notch is provided on the outer side of the connecting part; thus, the connecting part is not exposed in the lamp tube notch, resulting in better product integrity and aesthetics. The baffle plate extends below the notch, and at least one of the overlapping portions of the lower end of the baffle plate and the lower end of the notch is provided with a clearance slope; thus, the gap between the baffle plate and the lower end of the notch is smaller. Both the overlapping portions of the lower end of the baffle plate and the lower end of the notch are provided with clearance slopes; thus, the gap between the lower end of the baffle plate and the lower end of the notch is even smaller. A limiting part protruding from the lower end surface of the lamp holder is provided in the middle of the lower end surface of the lamp holder, and a groove corresponding to the limiting part is provided at the top of the lamp tube. The limiting part can abut against the bottom of the groove to limit the rotation angle of the lamp tube; thus, the gap between the limiting part and the bottom of the groove can be hidden, resulting in better product aesthetics.

The descriptions of component positions (including but not limited to: upper, lower, inner, outer, left, right, etc.) are for reference only when referring to the positions of the components shown in the accompanying drawings. Their purpose is to facilitate understanding of the relative relationships between the components and does not represent an absolute limitation on the scope of protection of this utility model. Those skilled in the art will understand that the description of relative positions may change when the view direction changes, but the essential relative positional relationships between the components remain unchanged.

[0015] refer to Figure 1An adjustable telescopic spotlight includes a cylindrical lamp barrel 1, a lamp holder 2, a mounting ring 3, and a storage tube 4. The lamp barrel 1 and the lamp holder 2 are connected by a hinge. The lamp holder 2 is slidably installed inside the storage tube 4, and the mounting ring 3 is installed on the outside of the opening in the storage tube 4. The lamp barrel 1 houses light source components such as a light source, a lens, and a reflector. The lamp holder 2 houses a driver power supply for the LED light source. The mounting ring 3 has a flange 31 at its lower end and an elastic pressure plate 32 with a torsion spring providing preload on its side. The flange 31 and the elastic pressure plate 32 of the mounting ring 3 are used to clamp the spotlight onto the inside and outside of the ceiling opening, thus securing it in place.

[0016] refer to Figure 1 The lamp tube 1 is a cylindrical body manufactured by die casting. A notch 11 extending to the top is provided on the upper end of its side wall. A fixed shaft 12 is provided within the notch 11. A first clearance slope 111 is provided on the side wall at the bottom of the notch 11. A groove 13 and a heat sink are provided at the top of the lamp tube 1.

[0017] refer to Figures 1 to 6A connecting portion 21 is provided on one side of the lower end face of the lamp holder 2, and a limiting portion 22 protruding from the lower end face of the lamp holder 2 and engaging with the groove 13 at the top of the lamp tube 1 is provided in the middle of the lower end face of the lamp holder 2. A mounting hole 23 with its axis perpendicular to the axis of the lamp holder 2 is provided in the connecting portion 21. The lamp holder 2 is rotatably sleeved on the fixed shaft 12 of the lamp tube 1 through the mounting hole 23, so that the two are hinged. A damping ring 5 is provided between the lamp holder 2 and the side wall of the storage tube 4, and the damping ring 5 provides resistance to the extension, sliding and fixing of the lamp holder 2 in the storage tube 5. A groove 41 is provided on the outer side wall of the storage tube 4 near the opening, and the mounting ring 3 is sleeved on the outside of the opening of the storage tube 4 through the groove 41. The lower end face of the mounting ring 3 protrudes from the opening of the storage tube 4, and a step 33 flush with the opening of the storage tube 4 is provided on its inner side. The step 33 can prevent the lamp holder 2 from sliding out of the opening of the storage tube and is a lower stop limiting mechanism for the sliding of the lamp holder 2. When the lamp holder 2 is at its lower stop point, its lower end face is located within the mounting ring 3, and the side wall of the mounting ring 3 can cover the gap between the upper end face of the lamp tube 1 and the lower end face of the lamp holder 2. A baffle 24, flush with the outer side of the connecting part 21, is provided on its outer side to cover the notch 11 on the side wall of the lamp tube 1. In this embodiment, the curvature of the baffle 24 is the same as that of the side wall of the lamp tube 1, forming a complete cylindrical outline with the side wall of the lamp tube 1. Of course, as an installation process requirement, a very small gap can be reserved between the two sides of the baffle 24 and the side wall of the lamp tube 1. As a more preferred solution, the length of the baffle 24 is longer than the length of the notch 11, and a second clearance slope 241, which cooperates with the first clearance slope 111, is provided at the overlap between the lower end of the baffle 24 and the lower end of the notch 11. Since the baffle 24 is flush with the outer side of the lamp tube 1 and the baffle 24 is longer than the length of the notch 11 on the side wall of the lamp tube, a clearance slope is provided at least one of the overlapping parts to reduce the gap between the lower end of the baffle 24 and the lower end of the notch 11; when clearance slopes are provided on both overlapping parts, the gap between the two is even smaller.

[0018] refer to Figure 4 When the axes of the lamp tube 1 and the lamp holder 2 coincide and the light emission angle is zero degrees, the limiting part 22 on the lamp holder 2 abuts against the bottom surface of the groove 13 at the upper end of the lamp tube 1 and limits its position. The groove 13 can cover the gap between the limiting part 22 and the bottom surface of the groove 13. The side wall of the mounting ring 3 can cover the gap between the upper end surface of the lamp tube 1 and the lower end surface of the lamp holder 2. The baffle 24 on the outside of the connecting part 21 can cover the notch 11 on the side wall of the lamp tube 1 and the gap below the notch 11. The gap between the moving parts of this utility model is small, the overall shape is strong, and the aesthetics are high.

[0019] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
