DETAILED DESCRIPTION

[0027] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The utility model relates to an angle-adjustable spotlight, which comprises a lamp tube 100, a lamp holder assembly 200 and a connecting piece 300.

[0029] like Figure 1 、 Figure 2 、 Figure 3and Figure 4 As shown, the interior of the lamp tube 100 is hollow to form a cavity 110, and both ends of the cavity 110 are open. In the direction shown in the figure, the axial direction of the cavity 110 is vertical, and the upper and lower ends are open. The lamp tube 100 includes a sliding portion 120, and the sliding portion 120 extends spherically from the lower end of the cavity 110 to the upper end. The sliding portion 120 is located at the lower part of the lamp tube 100, and the upper part of the lamp tube 100 can be set to a cylindrical shape. The sliding portion 120 can be set to an incomplete spherical shape, but a part of a sphere. Specifically, it can be a hemispherical shape, and the bottom opening of the hemispherical sliding portion 120 forms the lower end of the cavity 110, and the upper part of the hemispherical sliding portion 120 extends a cylindrical body with equal diameter to form the lamp tube 100. The inner and outer walls of the sliding portion 120 are both spherical. The inner wall of the sliding portion 120 is provided with a plurality of slots 121, which extend in a circular shape around the central axis of the cavity 110. The slots 121 are sequentially distributed along the axial direction of the cavity 110. The lamp holder assembly 200 is positioned below the lamp tube 100, with a portion of the upper portion of the lamp holder assembly 200 extending into the sliding portion 120. The connector 300 is positioned within the cavity 110 and is fixedly connected to the base of the lamp holder assembly 200 extending into the cavity 110. The connector 300 and the lamp holder assembly 200 can be secured to each other by means of screws, snaps, or other means. The sliding portion 120 is then clamped between the lamp holder assembly 200 and the connector 300, allowing the lamp tube 100 to move relative to the lamp holder assembly 200 via the sliding portion 120. This relative movement primarily involves axial rotation and swinging of the lamp tube 100 relative to the lamp holder assembly 200. The connector 300 is provided with a latching protrusion 310, which may be one, two, or more. The latching protrusion 310 latches into the latching slot 121 at the current alignment position. In actual use, a lamp element is installed in the lamp holder assembly 200. The lamp element may be a component such as a lamp board having LED lamp beads. A lampshade or other component may be installed on the end of the lamp tube 100 away from the lamp holder assembly 200. The light generated by the lamp element is radiated outward through the cavity 110. The lamp tube 100 guides the direction of the light. By swinging or rotating the lamp tube 100 relative to the lamp holder assembly 200, that is, changing the angular position of the lamp tube 100 relative to the lamp holder assembly 200, the direction of the light radiated outward after passing through the cavity 110 can be changed. When the lamp tube 100 moves relative to the lamp holder assembly 200, the latching protrusion 310 slides along the currently engaged latching slot 121, or slides out of one latching slot 121 and then slides into the next adjacent latching slot 121 to latch. The cooperation between the latching protrusion 310 and the latching groove 121 keeps the lamp tube 100 fixed at the current position relative to the lamp holder assembly 200. The lamp tube 100 can also be quickly adjusted to a central position relative to the lamp holder assembly 200, and will not shift due to insufficient friction during use.

[0030] In one embodiment, Figure 1 and Figure 2 As shown, the lamp holder assembly 200 includes a base 210 and a light guide base 220. The interior of the base 210 is hollow, and a lamp element can be installed. The light guide base 220 can be fixed to the base 210 by screw locking or the like. The light guide base 220 is provided with a light guide portion 221 in the shape of a hollow cylinder. The light guide portion 221 is inserted into the sliding portion 120 and extends into the cavity 110. The connecting member 300 is sleeved on the outside of the light guide portion 221, and the connecting member 300 can be fixed to the outside of the light guide portion 221 by screw locking or the like. The light generated by the lamp element in the base 210 is projected outward through the light guide portion 221 and the cavity 110 in turn. In the illustrated orientation, the base 210 is open upward, and the outer side of the sliding portion 120 abuts against the base 210. The inner side of the sliding portion 120 engages with the latching protrusion 310 on the connector 300 via the latching groove 121, thereby clamping the sliding portion 120 between the base 210 and the connector 300. The sliding portion 120 moves relative to the upper opening of the base 210.

[0031] Based on the above embodiments, Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the base 210 includes a main body 230 and a guide ring 240. In the direction shown in the figure, the interior of the main body 230 is hollow, and its upper end is open to form a mounting opening 231. The guide ring 240 is arranged in a circular ring shape, and the inner surface of the guide ring 240 is arranged in a spherical shape. The guide ring 240 is installed in the mounting opening 231. The outer surface of the sliding portion 120 is adapted to the shape of the inner surface of the guide ring 240. The outer wall of the sliding portion 120 abuts against the inner surface of the guide ring 240. When the lamp tube 100 rotates or swings relative to the lamp holder assembly 200, the outer wall of the sliding portion 120 abuts against the inner wall of the guide ring 240 and slides. The outer wall of the sliding portion 120 is supported by the guide ring 240, which is equivalent to the sliding portion 120 being clamped between the guide ring 240 and the connecting member 300. Among them, a step 232 is provided on the inner wall of the main body 230. The outer wall of the guide ring 240 is supported on the step 232. After the connector 300 is fixedly mounted on the light guide seat 220, the connector 300 exerts a force on the sliding portion 120 to press the sliding portion 120 downward toward the guide ring 240, and the sliding portion 120 exerts a force on the guide ring 240 to press the guide ring 240 downward toward the step 232, which is equivalent to the guide ring 240 being clamped and fixed between the sliding portion 120 and the step 232. Figure 2 and Figure 5 As shown, the inner side surface of the mounting opening 231 is spherical, and the outer wall of the sliding portion 120 can abut against the inner side surface of the mounting opening 231. On the one hand, it cooperates with the guide ring 240 to guide the movement of the lamp tube 100, and on the other hand, it can cooperate with the sliding portion 120 to shield the mounting opening 231 to prevent external debris from falling into the main body 230.

[0032] Among them, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the connecting member 300 is annular in shape. The circumferential outer wall of the connecting member 300 is spherical in shape, and a plurality of latching protrusions 310 are provided on the circumferential outer wall of the connecting member 300. The plurality of latching protrusions 310 are engaged with the latching grooves 121 to further improve the stability of the lamp tube 100 in the current position.

[0033] Based on the above embodiment, a plurality of latching protrusions 310 are distributed on the circumferential side wall of the connector 300. According to the distribution position of the latching protrusions 310 on the connector 300, the latching protrusions 310 include a first protrusion 311 and a second protrusion 312. The first protrusions 311 are distributed in sequence along the first circumference 301 on the outer wall of the connector 300. The second protrusions 312 are distributed in sequence along the second circumference 302 on the outer wall of the connector 300. The first circumference 301 and the second circumference 302 are coaxially arranged on the connector 300, and the diameter of the first circumference 301 is greater than the diameter of the second circumference 302. The distribution position of each first protrusion 311 and each second protrusion 312 is adapted to the distribution position of each latching groove 121 on the spherical surface of the sliding portion 120. Each first protrusion 311 and each second protrusion 312 is snapped into the corresponding slot 121 as the sliding portion 120 moves, thereby ensuring the stability of the lamp tube 100 in the current position. Furthermore, the connecting member 300 is provided with a plurality of first elastic arms 320 distributed in sequence along the circumferential direction. A second elastic arm 330 is provided between two adjacent first elastic arms 320. There is a gap between the first elastic arm 320 and the second elastic arm 330. The first elastic arm 320 and the second elastic arm 330 can both extend radially from the connecting member 300. The first protrusion 311 is provided on the outer end surface of the first elastic arm 320, and the second protrusion 312 is provided on the outer end surface of the second elastic arm 330. When the first protrusion 311 slides from one slot 121 to another slot 121, the first elastic arm 320 is subjected to force through the first protrusion 311 and elastically swings relative to the connecting member 300. When the second protrusion 312 slides from one slot 121 into the other, the second elastic arm 330 is subjected to force from the second protrusion 312, causing it to elastically swing relative to the connector 300. The first elastic arm 320 and the second elastic arm 330 can reduce the rigid friction between the first and second protrusions 311, 312 and the sidewalls of the slot 121 during their sliding in and out of the slot 121, thereby reducing wear on the slot walls of the slot 121 and the first and second protrusions 311, 312. The second elastic arm 330 includes a first elastic portion 331 and a second elastic portion 332. The first elastic portion 331 and the first elastic arm 320 are spaced apart along the first circumference 301. The second elastic portion 332 extends in an arc shape from the first elastic portion 331, from the first circumference 301 toward the second circumference 302. The second protrusion 312 is disposed on the second elastic portion 332. In this way, the first protrusions 311 and the second protrusions 312 are respectively distributed on the first circumference 301 and the second circumference 302. The second elastic portion 332 elastically swings relative to the connector 300 via the first elastic portion 331. A through hole 333 is provided in the middle of the first elastic portion 331, extending axially through the first elastic portion 331. The second elastic portion 332 extends from the outer wall of the first elastic portion 331, aligned with the through hole 333. The first elastic portion 331 and the second elastic portion 332 are arranged in a T-shape.When the second protrusion 312 is acted upon by an external force, the second elastic portion 332 can also undergo a certain elastic swing relative to the first elastic portion 331 .
