[0039] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0040] See also Figure 2 , which is a stretchable lighting spotlight 10 according to an embodiment of the present invention, including a housing 100 , a mounting assembly 200 and a lighting body 300 .

[0041] like Figures 2 to 4 As shown, the housing 100 is provided with a connected accommodating cavity 101 and a mounting opening 102. At least part of the structure of the lighting body 300 is located in the accommodating cavity 101. The mounting assembly 200 is disposed on the outer periphery of the housing 100 adjacent to the mounting opening 102. The lighting body 300 includes a stretching assembly 310, an annular heat dissipation joint 320, and a lighting assembly 330. The stretching assembly 310 is located in the accommodating cavity 101 so that the stretching assembly 310 can slide vertically in the accommodating cavity 101. Figure 3As shown, damping bumps 311 protrude from the outer wall of the stretching component 310, and the damping bumps 311 abut against the inner wall of the housing 100, so that after the stretching component 310 adjusts its height, the stretching component 310 hovers through the damping bumps 311; the annular heat dissipation joint 320 is used for rotation adjustment and heat dissipation of the merging optical component 333, and the stretching component 310 is partially disposed around the outer peripheral side of the annular heat dissipation joint 320; the lighting component 330 includes a rotating housing 331, a heat conducting block 332 and an optical component 333. The rotating housing 331 is provided with a receiving groove 3311. The heat conducting block 332 penetrates through the bottom of the receiving groove 3311 and abuts against the annular heat dissipation joint 320. The optical component 333 is mounted on one side of the heat conducting block 332背离 the bottom of the receiving groove 3311. The light emitting portion of the optical component 333 is disposed toward the opening of the rotating housing 331, so that the optical component 333 faces the opening of the rotating housing 331 and irradiates light to the outside. The rotating housing 331 of the optical component 333 is rotatably connected to the stretching component 310 through the annular heat dissipation joint 320. The rotating housing 331 is sleeved on the outer peripheral side of the annular heat dissipation joint 320, so that the rotating housing 331 rotates around the annular heat dissipation joint 320. Thus, when the optical component 333 works, the heat generated by it is conducted by the heat conducting block 332 and then dissipated to the outside by the annular heat dissipation joint 320, achieving a heat dissipation effect. In this embodiment, the length of the rotating housing 331 is 3.5 cm to 4.5 cm. Compared with the prior art, the overall length of the rotating housing 331 of the present disclosure is shorter, so that the distance between the optical component 333 and the opening of the rotating housing 331 is shorter (denoted as x2), and a better lighting effect is achieved. Further, the length of the rotating housing 331 is 4 cm.

[0042] In this embodiment, the annular heat dissipation joint 320 integrates rotation adjustment and heat dissipation, so that the heat generated when the optical component 333 is illuminated will be conducted by the heat conducting block 332, and finally the annular heat dissipation joint 320 receives the heat and dissipates the heat to the outside air, playing a heat dissipation role; the distance between the optical component 333 and the opening of the rotating housing 331 is shorter, that is, x2 < x1 (combined with Figure 1 and Figure 4 shown), so that the optical component 333 has a better lighting range and a better lighting effect. The above effects make the stretching type lighting spotlight 10 have a better heat dissipation effect and a relatively simple overall structure.

[0043] As Figure 4 、 Figure 5 and Figure 7As shown, in one embodiment, the annular heat dissipation joint 320 includes a rotating central axis 321, a first heat sink 322, a second heat sink 323 and a heat dissipation layer 324, the tensile component 310 is partially arranged around the outer peripheral side of the rotating central axis 321, the rotating shell 331 is sleeved on the outer peripheral side of the rotating central axis 321, the heat dissipation layer 324 covers both sides of the rotating central axis 321 respectively, the first heat sink 322 is arranged on the first side of the rotating central axis 321 through the heat dissipation layer 324, the second heat sink 323 is arranged on the second side of the rotating central axis 321 through the heat dissipation layer 324, and the optical component 333 is in contact with the rotating central axis 321. It can be understood that after the heat dissipation layer 324 is set on both sides of the rotating central axis 321, the first heat dissipation fin 322 covers the heat dissipation layer 324 on one side and is bonded to the first side of the rotating central axis 321, and the second heat dissipation fin 323 covers the heat dissipation layer 324 on the other side and is bonded to the second side of the rotating central axis 321 to prevent the heat dissipation layer 324 from overflowing. When the optical component 333 is illuminated, the heat generated by it is conducted to both sides of the rotating central axis 321 through the heat conductive block 332, and then dissipated from the first heat dissipation fin 322 and the second heat dissipation fin 323 to the outside through the heat dissipation layer 324, wherein the heat dissipation layer 324 is used to balance the temperatures of the first heat dissipation fin 322, the second heat dissipation fin 323 and the rotating central axis 321.

[0044] Further, combined with Figure 9 and Figure 10 As shown, the annular heat dissipation joint 320 further includes a rotating ring 325, which is sleeved on the rotating central axis 321 and connected to the rotating housing 331 so that when the rotating housing 331 rotates, the rotating ring 325 rotates accordingly. The tensioning assembly 310 is provided with an abutment plate 312, and the rotating ring 325 is provided with an abutment boss 3251, the end of which is movably connected to the abutment plate 312. It can be understood that the tensioning assembly 310 and the rotating housing 331 are rotationally connected via the rotating ring 325. When the rotating housing 331 rotates, the rotating ring 325 rotates accordingly, and the abutment boss 3251 also rotates accordingly, generating friction with the abutment plate 312 to achieve the rotational movement.

[0045] In another embodiment, the abutment plate is provided with an arc-shaped groove (not marked), and at least a portion of the abutment boss is slidably arranged in the arc-shaped groove. In this way, when the rotating shell rotates, the rotating shell drives the rotating ring to rotate with the rotating central axis as the center. At this time, the abutment boss synchronously rotates with the rotating central axis as the center, and the abutment boss rotates along the arc-shaped groove wall of the arc-shaped groove. Specifically, the arc center corresponding to the arc-shaped groove wall of the arc-shaped groove is located on the rotating central axis.

[0046] In another embodiment, there are two rotating rings, both of which are mounted on the rotating central axis. The two rotating rings are also fixedly connected to the rotating shell and the stretching assembly respectively, so that the rotating shell and the stretching assembly can rotate independently around the rotating central axis.

[0047] In one embodiment, the heat dissipation layer 324 is a flexible silicone grease sheet. It is understood that the flexible silicone grease sheet is used to fill the gap between the first heat sink 322 and the first side of the rotating shaft 321, and the gap between the second heat sink 323 and the second side of the rotating shaft 321. When the heat generated by the optical component 333 passes through the flexible silicone grease sheet, the flexible silicone grease sheet has the effect of equalizing the temperature of the rotating shaft 321, the first heat sink 322, and the second heat sink 323.

[0048] In one embodiment, the angle formed by the central axis of the stretching assembly 310 and the central axis of the rotating housing 331 ranges from 90° to 180° (not shown in the drawings). It can be understood that with the annular heat dissipation joint 320 as the vertex, the central axis of the stretching assembly 310 and the central axis of the rotating housing 331 are connected to the vertex to form a predetermined angle, and by adjusting the angle, the lighting angle range can be adjusted. Figure 3 As shown, the stretching component 310 is provided with a first abutting surface 310a, and the rotating shell 331 is provided with a second abutting surface 331a. When the central axis of the stretching component 310 and the central axis of the rotating shell 331 form an angle of 180°, the lighting direction of the optical component 333 is vertically downward. When rotated from the current angle to the extreme angle, the first abutting surface 310a and the second abutting surface 331a abut against each other. At this time, the central axis of the stretching component 310 and the central axis of the rotating shell 331 form an angle of 90°, and the optical component 333 illuminates in the horizontal direction.

[0049] like Figure 6 As shown in one embodiment, the optical component 333 includes a lighting element 3331, a reflective cup 3332, and a light emitting element 3333, which are connected in sequence. The lighting element 3331 is installed on the side of the heat conductive block 332 that is away from the bottom of the receiving groove 3311. The light emitting element 3333 is installed on the reflective cup 3332 near the opening of the rotating shell 331. The light emitting element 3333 is connected to the inner wall of the rotating shell 331. It can be understood that the lighting element 3331 is used to irradiate light to the outside world. During this period, part of the light passes through the reflective cup 3332 to achieve diffuse reflection and reduce the glare value of the light. The diffusely reflected light also passes through the light emitting element 3333. Figure 8 As shown, at this time, the light emitting member 3333 is provided with a plurality of light emitting holes 3333a, and the plurality of light emitting holes 3333a are arranged at intervals so that the light is refracted in the light emitting holes 3333a, thereby further reducing the glare value of the light. Even if the human eye looks directly at the optical component 333, the light will not cause damage to the human eye.

[0050] Furthermore, as Figure 8 shown, the cross-section of the light-emitting hole 3333a is hexagonal. It can be understood that the light-emitting member 3333 is provided with a plurality of light-emitting holes 3333a in a hexagonal shape, and the plurality of light-emitting holes 3333a are of a hexagonal structure. The hexagonal structure has the highest density, the simplest required materials, and the largest available space, making this structure have great applications in geometry, material science, etc.

[0051] The present disclosure also provides an illumination system, including the telescopic lighting spotlight 10 of any one of the above embodiments.

[0052] Compared with the prior art, the present disclosure includes but is not limited to the following advantages:

[0053] For the above-mentioned telescopic lighting spotlight 10, the annular heat dissipation joint 320 integrates rotation adjustment and heat dissipation. When the optical component 333 is illuminated, the generated heat will be conducted through the heat conduction block 332, and finally receive heat from the annular heat dissipation joint 320 and dissipate the heat into the external air, playing a role in heat dissipation; the distance between the optical component 333 and the opening of the rotating housing 331 is relatively short (denoted as x2), that is, x2 < x1, so that the optical component 333 has a better illumination range and a better illumination effect. The above effects make the telescopic lighting spotlight 10 have a better heat dissipation effect and a relatively simple overall structure.

[0054] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
