[0023] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0024] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0025] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0026] The embodiment of the present invention provides a row of track lights with adjustable angles, such as Figure 1-5 As shown, the lamp includes a base 100 that can slide with the track and a lamp holder 200 mounted on the base 100. The track can be provided with a track groove, and the base 100 is embedded in the track groove and can slide along the track groove. The lamp holder 200 is located outside the track groove to facilitate its angle adjustment. Both ends of the base 100 are provided with upwardly protruding connecting plates 110, which also extend outside the track groove. A lamp assembly 300 is fixed within the lamp holder 200. The lamp assembly 300 includes a plurality of light-emitting devices 310 distributed along the length of the lamp holder 200. The light-emitting devices 310 emit light when powered, thereby forming a row of lamps. The lamp holder 200 is disposed between two connecting plates 110, and the two ends of the lamp holder 200 are rotatably connected to the two connecting plates 110. Therefore, the lamp holder 200 can rotate relative to the base 100, thereby adjusting the angle of the lamp holder 200 and changing the angle of the light to enrich the lighting effect.

[0027] Among them, the rotational connection between the lamp holder 200 and the connecting plate 110 may have damping so that the lamp holder 200 will not reset itself under the action of its own weight. The lamp holder 200 can maintain the adjusted angle through the damping force. Since damped rotation is already a conventional technical means in this field, how to achieve damped rotation between the lamp holder 200 and the connecting plate 110 will not be elaborated.

[0028] In some embodiments, the lamp holder 200 includes a shell 210 and two cover plates 220. The shell 210 can be roughly cylindrical. A receiving groove 211 is provided on the side of the shell 210. The receiving groove 211 penetrates the shell 210 along the length direction of the shell 210. The lamp assembly 300 can be slidably inserted into the receiving groove 211 along the length direction of the shell 210, that is, the lamp assembly 300 can be inserted into the receiving groove 211 from the end of the shell 210 along the length direction of the shell 210, and can also be pulled out from the receiving groove 211 at the end of the shell 210. The two cover plates 220 are respectively detachably fixed at the two ends of the shell 210 in the length direction, and the two cover plates 220 respectively cover the openings of the receiving groove 211 at the two ends of the length direction of the shell 210, and the cover plates 220 are used to limit the lamp assembly 300 from being separated from the shell 210. Therefore, the lamp assembly 300 of this embodiment is slidably inserted into the receiving groove 211 and then limited by the cover plate 220 , so as to facilitate the assembly and disassembly of the lamp holder 200 .

[0029] The two cover plates 220 are rotatably connected to the two connecting plates 110. Both cover plates 220 can be detachably fixed to the two ends of the housing 210 in the longitudinal direction by screws. Countersunk holes can be provided on the cover plates 220 to accommodate the heads of the screws to avoid interference with the rotational connection between the cover plates 220 and the connecting plates 110.

[0030] Furthermore, the lamp assembly 300 includes a circuit board 320, a bracket 330, a light guide plate 340, and a top plate 350. The light-emitting device 310 is fixed on the circuit board 320 and distributed along the length direction of the lamp holder 200. The light-emitting device 310 can specifically be an LED lamp bead. The bracket 330 is arranged above the circuit board 320, and a reflective cup 331 is provided on the bracket 330 to cover the outside of the light-emitting device 310. The reflective cup 331 can be integrally formed with the bracket 330 or fixed to the bracket 330. The light guide plate 340 is fixed to the top surface of the bracket 330. The top plate 350 is arranged above the light guide plate 340, and a light guide column 351 is provided on the bottom surface of the top plate 350. The light guide column 351 is provided with a light-transmitting hole 352 that passes through itself and the top plate 350, and the light-transmitting hole 352 is connected to the reflective cup 331.

[0031] When the light-emitting device 310 is powered on, it emits light. Some of the light is directed directly toward the light guide plate 340, while another portion is reflected by the reflective cup 331 and then directed toward the light guide plate 340. The light guide plate 340 guides the light, making it more uniform and soft. The light that passes through the light guide plate 340 is then emitted through the light hole 352. When the lamp holder 200 rotates, the light hole 352 also rotates accordingly. Therefore, the angle of the light will be determined by the angle of the light hole 352.

[0032] In some embodiments, a downwardly extending insert plate 353 is provided on the bottom surface of the top plate 350, a through hole 341 is provided on the light guide plate 340 to match the insert plate 353, and a socket 332 is provided on the bracket 330 to match the insert plate 353. The insert plate 353 passes through the through hole 341 and is inserted into the socket 332, thereby fixing the top plate 350, light guide plate 340, and bracket 330 together. The insert plate 353 can be snap-fitted into the socket 332.

[0033] Furthermore, the bracket 330 can be fixedly connected to the circuit board 320 by various methods such as screw fixation and adhesive fixation, so that the top plate 350, the light guide plate 340, the bracket 330 and the circuit board 320 are combined and fixed together.

[0034] In some embodiments, both sidewalls of the receiving groove 211 are provided with connecting grooves 212, and the two sides of the top plate 350 are respectively slidably inserted into the two connecting grooves 212. On the one hand, the sliding fit between the top plate 350 and the connecting grooves 212 guides the lamp assembly 300 to be smoothly inserted into the receiving groove 211. On the other hand, the connecting grooves 212 can limit the top plate 350, making it difficult for the entire lamp assembly 300 to move relative to the housing 210 in the depth direction of the receiving groove 211, and the lamp assembly 300 can be stably fixed in the receiving groove 211.

[0035] In some embodiments, the inner side surfaces of the two connecting plates 110 facing each other are provided with coaxial convex rings 120, and the outer side surfaces of the two cover plates 220 are provided with coaxial connecting columns 221. The connecting columns 221 on the two cover plates 220 are respectively inserted into the convex rings 120 on the two connecting plates 110 and can rotate in the convex rings 120 to realize the rotational connection between the two cover plates 220 and the two connecting plates 110 respectively.

[0036] Furthermore, a wiring hole 222 is provided at the axis of the connecting post 221, a wiring groove 130 is provided on the inner side of the connecting plate 110, and it mates with the wiring hole 222. The protruding ring 120 is provided with a notch corresponding to the wiring groove 130. The wiring groove 130 can extend vertically to the base 100, and the wires that supply power to the circuit board can be led out from the wiring hole 222 and then routed along the wiring groove 130. The bottom of the base 100 is typically equipped with an electrode plate that contacts the embedded wires in the track. The wires can be connected to the electrode plate, thereby supplying power to the circuit board, allowing the entire track light to operate.

[0037] In some embodiments, both connecting plates 110 can be detachably fixed to the ends of the base 100, which facilitates assembly and disassembly of the lamp holder 200 and the connecting plates 110. Both connecting plates 110 can be fixed to the ends of the base 100 by screws.
