[0029] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0030] Embodiment 1:

[0031] The utility model provides a light adjustment mechanism in accordance with Figures 1 to 10 As shown, it includes a base 1, a first light source 2, an adjustment component 5 and a connecting member 4, wherein two ends of the first light source 2 are hinged to the base 1 and form a hinge, and two ends of the connecting member 4 are respectively an active part and a driven part, the active part is connected to the adjustment component 5, and the driven part is connected to the first light source 2, and the adjustment component 5 drives the active part to swing up and down through an external force, and the active part synchronously drives the driven part to swing up and down, so that the driven part drives the first light source 2 to rotate at the hinge.

[0032] like Figures 1 to 4 As shown, the base 1 includes a housing 17, and a first connecting member 411 and a second connecting member 412 connected to the left and right ends of the housing 17. The first connecting member 411 and the second connecting member 412 are both provided with a rotating shaft 13, and both ends of the first light source 2 are provided with a rotating groove 22 adapted to the rotating shaft 13, and the rotating shaft 13 is rotatably hinged in the rotating groove 22 to form the hinge. The two ends of the first light source 2 are hinged to the base 1 through the rotating shaft 13.

[0033] The base 1 is provided with a first light emitting plate 15 corresponding to the first light source 2. The front and rear surfaces of the first light source 2 are a light emitting surface and a backlight surface, respectively. The light emitting surface and the backlight surface are coaxially arranged. The light emitting surface is close to the first light emitting plate 15. The driven part is connected to the backlight surface. The driven part drives the backlight surface to flip up and down. The upward flipping of the backlight surface drives the light emitting surface to flip down. The downward flipping of the backlight surface drives the light emitting surface to flip up, thereby changing the angle at which the first light source 2 emits light from the first light emitting plate 15.

[0034] The connecting member 4 plays a role in transmitting force. The adjusting component 5 drives one end of the connecting member 4 to swing up and down through external force, and the other end of the connecting member 4 drives the first light source 2 to rotate along the rotating shaft 13, thereby adjusting the light emitting direction. This structure is simple and ingenious, and the user can adjust the irradiation direction of the light emitting surface according to needs, so as to adapt to different use environments and make the irradiation direction no longer single.

[0035] like Figures 5 to 7As shown, preferably, the driven part is a clamping part 41, and the first light source 2 is provided with a clamping groove 21 adapted to the clamping part 41, and the clamping part 41 is clamped in the clamping groove 21 to drive the first light source 2 to rotate. The clamping part 41 is in the shape of a clip, and the upper and lower ends of the first light source 2 are both recessed inwardly with the clamping groove 21, and the two ends of the clamping part 41 are respectively clamped in the clamping grooves 21 at the upper and lower ends of the first light source 2, and the connecting member 4 drives the backlight surface to flip through the clamping part 41, and the backlight surface drives the first light source 2 to flip, thereby adjusting the irradiation angle of the light emitting surface. This arrangement can facilitate the rotation of the first light source 2 while maintaining the stability of the connection between the connecting member 4 and the first light source 2.

[0036] by Figure 5 Taking the direction and structure shown as an example, in embodiment one, the adjustment component 5 includes a first bolt 51 and a tension spring 52, the active part is a hook part 42, and the upper end of the first bolt 51 abuts against the lower bottom surface of the hook part 42; when an external force drives the first bolt 51 to move upward, the first bolt 51 drives the hook part 42 to move upward; when an external force drives the first bolt 51 to move downward, the tension spring 52 drives the hook part 42 to move downward.

[0037] The light adjustment mechanism further comprises a fixing seat 6 , the first bolt 51 is screwed on the fixing seat 6 , a limit block 61 is fixed on the fixing seat 6 , and two ends of the tension spring 52 are respectively connected to the limit block 61 and the hook portion 42 .

[0038] like Figure 5 and Figure 6 As shown, the fixing seat 6 is fixed in the housing 17, and a cavity 63 is provided in the fixing seat 6. The first bolt 51 is accommodated in the cavity 63. An opening is provided at the top of the fixing seat 6, and the upper end of the first bolt 51 extends out of the opening. An internal thread matching the first bolt 51 is provided at the opening, and the rotation fixation of the first bolt 51 is achieved through the internal thread. The position of the limit block 61 is fixed, and the limit block 61 and the hook portion 42 are both provided with through holes. The two ends of the tension spring 52 pass through the two through holes respectively to connect the limit block 61 and the hook portion 42. The hook portion 42 is a rod-shaped structure, and the first bolt 51 abuts against the lower bottom surface of the hook portion 42.

[0039] When the first bolt 51 is rotated upward, the first bolt 51 pushes the hook portion 42 upward, and the hook portion 42 swings upward to drive the clamping portion 41 to swing downward, and the clamping portion 41 drives the first light source 2 to flip downward, thereby lowering the illumination angle of the light-emitting surface, and the tension spring 52 is in a stretched state. When the first bolt 51 is rotated downward, the first bolt 51 moves downward, and the hook portion 42 swings downward under the tension of the tension spring 52, and the hook portion 42 drives the clamping portion 41 to swing upward, and the clamping portion 41 drives the first light source 2 to flip upward, thereby raising the illumination angle of the light-emitting surface.

[0040] In the first embodiment, the user adjusts the first bolt 51 to move up and down, and needs to adjust from the lower end of the first bolt 51. The lower end of the first bolt 51 is located on the lower bottom surface of the base 1, and the movement of the first bolt 51 is almost all carried out in the cavity 63, and is almost not exposed on the outer surface of the base 1. This arrangement is more beautiful and has a dust and water-proof effect. Some lighting adjustment mechanisms on the market set the adjustment part on the outer surface of the base 1, which is not only not beautiful, but also easy to get dust and water, and be worn. It is also easy to be adjusted at will by passers-by, so that the lighting angle cannot reach the optimal position. In the first embodiment, the lighting adjustment mechanism is built into the base 1, and the adjustment position of the first bolt 51 is hidden. It is not easy to get water and wear, and after the installer adjusts the lighting angle according to the installation environment, it is not easy to be changed at will by passers-by.

[0041] Embodiment 2:

[0042] like Figure 7 and Figure 8 As shown, the difference between the first embodiment and the second embodiment is that: Figure 7 Taking the direction and structure shown as an example, in Example 2, the adjusting assembly 5 includes a second bolt 53 and a traction sleeve 54, and the traction sleeve 54 is arranged on the second bolt 53 through a threaded sleeve. When the second bolt 53 is rotated circumferentially by an external force, the second bolt 53 drives the traction sleeve 54 to move up and down along the second bolt 53, and the active part is the limiting part 43, and the traction sleeve 54 drives the limiting part 43 to swing up and down along the second bolt 53.

[0043] like Figure 8As shown, the traction sleeve 54 includes a circle and two driving rods 541 symmetrically extending and arranged. The circle is provided with an internal thread matched with the second bolt 53. The second bolt 53 only rotates and does not move up and down. When the second bolt 53 rotates clockwise, the traction sleeve 54 moves upward along the second bolt 53 under the action of the internal thread, and the traction sleeve 54 drives the limiting part 43 to move upward together. When the limiting part 43 moves upward, it drives the clamping part 41 to move upward, so that the clamping part 41 drives the first light source 2 to flip downward to lower the illumination angle of the light emitting surface.

[0044] When the second bolt 53 rotates counterclockwise, the traction sleeve 54 moves downward along the second bolt 53 under the action of the internal thread, and the traction sleeve 54 drives the limit portion 43 to move downward together. When the limit portion 43 moves downward, it drives the clamping portion 41 to move downward, so that the clamping portion 41 drives the first light source 2 to flip upward to increase the illumination angle of the light emitting surface. It is worth noting that the up-and-down relative movement relationship between the second bolt 53 and the traction sleeve 54 is affected by the rotation direction of the thread. When the rotation direction of the thread changes, the corresponding relationship between the clockwise rotation or counterclockwise rotation of the second bolt 53 and the upward or downward movement of the traction sleeve 54 will also change relatively.

[0045] The limiting portion 43 is provided with two limiting grooves 431 , and the two ends of the traction sleeve 54 are respectively placed in the two limiting grooves 431 .

[0046] like Fig. 9 As shown, there are two limit grooves 431, and the limit part 43 and the traction sleeve 54 are symmetrical structures. The driving rods 541 at both ends of the traction sleeve 54 are respectively placed in the two limit grooves 431 and move in the limit grooves 431. Through the cooperation between the driving rod 541 and the limit groove 431, the traction sleeve 54 drives the limit part 43 to move synchronously. The limit groove 431 limits the driving rod 541 and also reserves a swinging space for the driving rod 541.

[0047] The limiting portion 43 is symmetrically provided with two side walls, an escape opening 432 is formed between the two side walls, the second bolt 53 is placed in and passes through the escape opening 432, and the two limiting grooves 431 are respectively provided on the two side walls.

[0048] like Fig. 9As shown, the avoidance opening 432 is U-shaped, and the circle is also arranged in the avoidance opening 432. The two side walls facilitate the driving rod 541 to drive the limiting part 43 to swing up and down without affecting the upward and downward movement of the limiting sleeve.

[0049] The light adjustment mechanism further includes a fixing seat 6 , in which a fixing member 62 is disposed. The fixing member 62 is fixed to the lower portion of the second bolt 53 so that the second bolt 53 remains in a vertical position when rotating circumferentially.

[0050] like Figure 8 As shown, the fixing seat 6 is fixed in the housing 17, a cavity 63 is provided in the fixing seat 6, the second bolt 53 is passed through the cavity 63, the cavity 63 is narrow at the top and wide at the bottom, and the size of the fixing member 62 is adapted to the size of the lower part of the cavity 63, so that the fixing member 62 is accommodated in the lower part of the cavity 63 and cannot move upward.

[0051] The fixing member 62 is provided with a through hole, and the through hole is provided with an internal thread matched with the second bolt 53, and the second bolt 53 passes through the through hole. When the second bolt 53 is rotated, the fixing member 62 rotates relative to the fixing seat 6 but does not move up and down. Under the action of the fixing member 62, the second bolt 53 only rotates spirally and does not move up and down. The fixing member 62 can be a nut.

[0052] In the second embodiment, the lower end of the second bolt 53 is also arranged on the lower bottom surface of the base 1. When the user adjusts the second bolt 53, the second bolt 53 only rotates without displacement in the up and down directions. It is almost not exposed on the outer surface of the base 1, and also plays the role of aesthetics, dustproof and waterproof.

[0053] like Fig.10 As shown, the utility model also provides a lawn lamp 100, including the light adjustment mechanism as described above. The lawn lamp 100 also includes a bottom bracket 8 and a lamp frame 7, the light adjustment mechanism is arranged in the base 1, the lamp frame 7 is mounted on the bottom bracket 8, and the base 1 is mounted on the lamp frame 7.

[0054] The fixing base 6 is fixed in the base 1 by bolts, and the first light source 2 is installed on the side surface of the base 1. The lawn lamp 100 is fixed on the installation surface by the bottom bracket 8, and the installation surface can be a sidewalk or a lawn. The base 1 is installed above the lamp frame 7, so that the entire lawn lamp 100 is more beautiful and the illumination height is more suitable.

[0055] like Figure 1 and Figure 2As shown, the base 1 is provided with a second light source 3 and a through installation cavity 14, and the second light source 3 can be detachably installed in the installation cavity 14 along the through direction of the installation cavity 14; the second light source 3 is connected to a sliding rod 31, and a through sliding groove 141 is provided on the installation cavity 14, and the sliding rod 31 can be detachably slid in the sliding groove 141 along the through direction of the sliding groove 141, so as to facilitate the disassembly and assembly of the second light source 3 from the installation cavity 14.

[0056] like Fig.10 As shown, a second light emitting plate 16 corresponding to the second light source 3 is installed on the base 1, and the light emitting surface of the second light source 3 corresponds to the second light emitting plate 16. The second light emitting plate 16 is installed on the lower bottom surface of the base 1, and the horizontal plane where the first light source 2 is located is adjacent to the horizontal plane where the second light source 3 is located. This arrangement allows the lawn lamp 100 to illuminate the front and the bottom at the same time, and is suitable for installation on a pedestrian walkway, and can illuminate roadside shrubs and the walkway at the same time.

[0057] The installation cavity 14 is arranged around the second light emitting plate 16 to facilitate fixing the position of the second light source 3. The two ends of the installation cavity 14 are respectively connected to the first connecting member 411 and the second connecting member 412. The slide groove 141 is arranged on the upper end surface of the installation cavity 14. Preferably, a handle is arranged on the slide bar 31, and the handle extends out of the slide groove 141, so that the user can drive the slide bar 141 to slide on the slide groove 141 through the handle, so as to facilitate the installation and removal of the second light source 3.

[0058] Preferably, a battery for supplying power to the first light source 2 and the second light source 3 is disposed in the base 1 , and the battery may be installed in the same manner as the second light source 3 .
