[0002] In the context of energy conservation and environmental protection, LED lamps are increasingly used in home and commercial lighting due to their high light output efficiency and good focusing performance. In places such as exhibition halls, jewelry stores, museums, supermarkets, and some home lighting, such as in large villas. With the extensive use of LED lamps, especially strip lamps, these home or commercial lighting are closer to the real needs of users. In some areas of use such as wall washers and lawn lamps, it is often necessary to change the projection direction of the lamp to meet the lighting needs of users.

[0003] For example, the patent document with announcement number CN205807043U discloses an angle adjustment mechanism for an LED strip light, which includes end covers located at both ends of the lamp body, the end covers are provided with a threading tube extending along the axial direction of the lamp body, the threading tube is provided with a lamp holder and a gear, wherein the edge of the gear is accommodated in the opening of the lamp holder, the gear teeth of the gear cooperate with the limiting teeth on the limiting plate, the limiting plate is located in the outer end cover, when the lamp holder is rotated, the gear will rotate driven by the lamp holder, the limiting plate will be deformed by the force of the gear, thereby changing the position of meshing with the gear, limiting the lamp body at the current angle, thereby realizing adjustable light output angle.

[0004] Although the above structure can adjust different light output angles, since the limit plate and the gear are separate components, the number of assembly steps is increased and the assembly takes a long time. At the same time, since the limit plate is located in the slide groove of the outer end cover, it is easy to fall off the slide groove due to vibration and other reasons, resulting in the inability to effectively cooperate with the gear, thereby affecting the dimming effect.

[0024] The following further elaborates on specific embodiments of the present invention based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.

[0025] As Figures 1 to 5 shown, the adjustable-angle strip lamp of this embodiment includes a lamp body 100, end caps 200 provided at both ends of the lamp body 100, and a fixed seat 300 connected to the end caps 200. The lamp body 100 has a central axis 101. The end caps 200 rotate relative to the fixed seat 300 around the central axis 101, and an elastic clamping seat 400 and a gear 500 for limiting the rotation are provided therebetween. In this embodiment, the connection manner between the lamp body 100 and between the lamp body 100 and the end caps 200 is not the focus of the present invention. An existing lamp body structure can be adopted, which generally includes a lamp holder, a circuit board with a light source, and a lens (lamp shade). End caps 200 are fixed at both ends of the lamp holder. In this embodiment, the lamp body 100 rotates around the central axis 101.

[0026] In the prior art, in order to achieve a more flexible lighting method, a strip lamp with a large irradiation area is set in an angle-adjustable form, that is, the lamp body can rotate relative to the fixed seat. At the same time, the position also needs to be locked. There are many methods to achieve the above functions. Generally, the end cap and the fixed seat are set to rotate relative to the central axis, and an elastic clamping seat and a gear are respectively provided therebetween. The elastic clamping seat has elasticity in the radial direction (radial direction relative to the central axis). When the end cap and the fixed seat rotate relative to each other, it enters and exits the tooth grooves of the gear, and the elastic clamping seat and the gear cooperate to achieve the locking position. The elastic clamping seat is provided on one of the end cap and the fixed seat, while the gear is provided on the other part. In this embodiment, in order to simplify the structure, the following improvements are made.

[0027] Among them, the elastic clamping seat and the gear can be provided at only one end, or both ends can be provided.

[0028] In this embodiment, one end of the elastic clamping seat 400 is fixed on the end cap 200 or the fixed seat 300, and the other end is a free end extending axially to the gear 500. A protrusion 401 meshing with the gear 500 is provided on the elastic clamping seat 400. The above elastic clamping seat 400 can be made of a material with certain plasticity such as metal or plastic, so that when one end is fixed, the other end has elasticity. Through this simple form, the cooperation between the elastic clamping seat 400 and the gear 500 is realized, with a simple structure and convenient manufacturing.

[0029] In order to simplify the connection method between the end cover 200 and the fixing seat 300, in this embodiment, a plurality of elastic buckles 201 that are spaced apart around the central axis 101 to form a rotating shaft 202 are provided on the end cover 200, and a shaft sleeve 301 that cooperates with the rotating shaft 202 is provided on the fixing seat 300. The hook portion of the buckle 201 is snap-fitted with the side of the shaft sleeve 301 away from the end cover 200. One end of the elastic buckle 201 is used for fixing, the middle area is used to form the rotating shaft 202, and the barb at the end is used as a connection structure. The above-mentioned elastic buckle 201 not only has the function of a rotating shaft but also realizes axial fixation, simplifying the structure.

[0030] In order to make the relative rotation smoother and more stable, the elastic buckle 201 is a first arc-shaped elastic piece bent around the central axis. A plurality of first arc-shaped elastic pieces bent around the central axis can form a form similar to a cylinder, with a better matching degree with the shaft sleeve. In this embodiment, four elastic buckles 201 are provided, two in a group and symmetrically arranged.

[0031] The fixing method of the elastic buckle 201 and the end cover 200 can adopt a fixing structure such as a screw. In order to further simplify the structure, the elastic buckle 201 and the end cover 200 in this embodiment are integrally formed.

[0032] In order to make the structure more compact, in this embodiment, the elastic seat 400 is a second arc-shaped elastic piece provided between adjacent elastic buckles 201, and the protrusion 401 is provided on the outer surface of the second arc-shaped elastic piece. Thereby, the radial space is saved, making the components more compact.

[0033] In order to facilitate the setting of the cam, a diameter-expanded section is provided on the side of the shaft sleeve 301 close to the end cover 200. The gear 500 is an internal gear provided on the diameter-expanded section, and the internal gear, the shaft sleeve 301 and the fixing seat 300 are integrally formed. In the above structure, when the end cover 200 is inserted into the shaft sleeve 301 of the fixing seat 300, the cooperation is completed, and the assembly is simple and fast. The gear 500 can be continuous or disconnected, and can be set according to the requirements of the rotation angle.

[0034] The fixing method of the elastic seat 400 and the end cover 200 can adopt a fixing structure such as a screw. In order to further simplify the structure, the elastic seat 400 and the end cover 200 are integrally formed.

[0035] In order to ensure stable rotation, a plurality of elastic seats 400 are provided and are symmetrically distributed around the central axis 101. In this embodiment, two are provided, one above and one below. The gear 500 is two disconnected segments, and is arranged corresponding to the upper and lower elastic seats 400.

[0036] In order to prevent over-rotation, in this embodiment, a limit protrusion 302 for preventing over-rotation is provided on the side of the shaft sleeve 301 away from the end cover 200, and the limit protrusion 302 is in limit cooperation with the hook portion of the elastic buckle 201. The limit protrusion 302 can be integrally formed.

[0037] To make the structure more compact, a wire passing hole 203 is provided on the end cover 200, and the wire passing hole 203 is arranged within the area surrounded by the elastic buckle 201.

[0038] The above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are all covered within the scope of the claims of the present invention.
