It should be noted that the lamp holder 2 is installed on a corresponding lamp holder and support component. The angle of the lamp holder 2 can be adjusted, so that the light direction of the lamp body 1 can be adjusted.

[0040] With reference to Figures 2 to 5 , Figure 7 and Figure 8 , the angle adjusting device further comprises a plurality of light shielding plates 3 and two groups of partition plates 4, the light shielding plates 3 and the partition plates 4 are arc-shaped and the edges are matched, the plurality of light shielding plates 3 are distributed on both sides of the guide frame 22, the two groups of partition plates 4 are distributed on both sides of the guide frame 22, and the plurality of light shielding plates 3 are distributed on both sides of the partition plates 4; a plurality of sliding grooves 11 are formed on the shell of the lamp body 1, a tooth groove 12 is arranged in the sliding groove 11 at the center of the shell of the lamp body 1, a first sliding block 31 is fixedly installed on the light shielding plate 3, a positioning hole 32 is formed on one side of the light shielding plate 3, and a spring pin 5 is installed at the other end, the light shielding plate 3 is slidably connected with the shell of the lamp body 1 through the first sliding block 31 and the sliding groove 11; a second sliding block 41 is fixedly installed on the partition plate 4, the partition plate 4 is slidably connected with the sliding groove 11 through the second sliding block 41, and the second sliding block 41 is slidably connected with the sliding groove 11, the second sliding block 41 is fixedly installed with a first elastic sheet 42, the first elastic sheet 42 is inserted into the tooth groove 12, the partition plate 4 is limited, the relative stability of the partition plate 4 and the lamp body 1 is maintained, and the spring pin 5 is installed on both sides of the partition plate 4.

[0041] With reference to Figure 9 and Figure 10 , the spring pin 5 comprises a pin sleeve 51, a plurality of pin sleeves 51 are respectively installed on the light shielding plate 3 and the partition plate 4, a pin head 52 is slidably connected with the pin sleeve 51, a first elastic member 53 for pushing the pin head 52 to move outward of the pin sleeve 51 is installed in the pin sleeve 51, a jacking rod 54 penetrating through the pin sleeve 51 is fixedly installed on the pin head 52, the pin head 52 is inserted into the positioning hole 32, the adjacent two light shielding plates 3 are limited and connected by inserting the pin head 52 into the corresponding positioning hole 32, and the pin head 52 of the spring pin 5 on the partition plate 4 is inserted into the positioning hole 32 of the adjacent light shielding plate 3 to limit and connect the partition plate 4 and the adjacent light shielding plate 3.

[0042] With reference to Figure 1 , Figure 6 and Figure 11A pushing assembly 6 is installed on the guide frame 22. The pushing assembly 6 includes a limiting tube 61. A telescopic rod 62 is slidably connected inside the limiting tube 61. The telescopic rod 62 is slidably connected to the guide frame 22 through a guide block 63 fixed at its end. A second elastic element 64 is installed inside the limiting tube 61. One end of the second elastic element 64 abuts against the limiting tube 61, and the other end abuts against the telescopic rod 62, for pushing the limiting tube 61 upward. A limiting block 65 is fixedly installed on the limiting tube 61. When the second elastic element 64 pushes the limiting tube 61 upward, it abuts against the guide frame 22 through the limiting block 65, thereby limiting the limiting tube 61 at the maximum displacement. Two sets of push rods 66 are fixedly installed on the limiting tube 61. The diameter of the push rods 66 is smaller than the height of the through hole 23. The pressure limiting tube 61 compresses the second elastic element 64, aligning the height of the push rod 66 with the height of the through hole 23. By rotating the limiting tube 61, the push rod 66 is driven to rotate, thus allowing the push rod 66 to pass through the through hole 23. At this time, when the limiting tube 61 moves on the guide frame 22, the push rod 66 can push the top rod 54, thereby retracting the pin head 52 into the pin sleeve 51, thus releasing the limitation on the two adjacent light shields 3 or the light shield 3 and the partition 4.

[0043] Reference Figure 2 , Figures 12 to 15 Both ends of the lamp holder 2 are equipped with adjustment components 7. Each adjustment component 7 includes a coaxial support rod 71 and a support tube 72. The axis of the support rod 71 is collinear with the rotation axis of the light shield 3. The support tube 72 is fitted onto the outside of the support rod 71 without contacting it. Both the support rod 71 and the support tube 72 are rotatably connected to the support frame 21. A first end cap 73 is fixedly installed on the support rod 71. The light shield 3 adjacent to the first end cap 73 is connected to the first end cap 73 by a pin 52 inserted into the first end cap 73 to achieve a limiting connection. A second... The end cap 74, adjacent to the light shield 3, is connected to the second end cap 74 by a pin 52. The first end cap 73 and the second end cap 74 form a semi-circle. The support rod 71 has a reversing groove 75, and the support tube 72 has an arc-shaped groove 76. The reversing groove 75 and the arc-shaped groove 76 are designed with opposite spiral grooves, one is left-handed and the other is right-handed. The adjustment assembly 7 also includes a lever 77 inserted into the reversing groove 75 and the arc-shaped groove 76. The lever 77 is slidably connected to the support frame 21. When the support rod 71 rotates counterclockwise to drive the first end cap 73 to rotate, the lever 77 slides on the support frame 21 under the action of the reversing groove 75. When the lever 77 slides, the support tube 72 rotates clockwise under the action of the arc-shaped groove 76, thereby driving the second end cap 74 to rotate clockwise, thus achieving the blocking of the light at the end.

[0044] The second elastic sheet 78 is fixedly installed on the support rod 71, the adjusting assembly 7 further comprises a gear ring 79 fixedly installed on the support frame 21, the gear ring 79 is coaxially arranged with the support rod 71, and the second elastic sheet 78 is clamped in the slot gap of the gear ring 79 to limit the rotation of the support rod 71.

[0045] Working principle: when the light width needs to be shortened, i.e. the light width is shortened from both sides of the lamp body 1, the push-up assembly 6 is manually moved to the end, the push rod 66 is turned out of the through hole 23 by being pressed and rotated, the push rod 66 pushes the top rod 54 by moving the limiting tube 61, and then the pin head 52 is retracted into the pin sleeve 51, until the push rod 66 is buckled into the limiting slot 24 under the action of the second elastic element 64, the pin head 52 is kept stable, at this time, the corresponding light shield plate 3 of the spring pin 5 and the end cover at one end of the lamp body 1 are released from the limiting, the first end cover 73 is driven to rotate by manually rotating the support rod 71 at both ends, the light shield plate 3 limited by the first end cover 73 and the partition plate 4 limited by the light shield plate 3 are synchronously rotated, the push rod 77 is driven to slide on the support frame 21 by the reversing slot 75, when the push rod 77 slides, the support tube 72 is driven to rotate clockwise by the arc-shaped slot 76, and then the second end cover 74 is driven to rotate clockwise, and the light shield plate 3 limited by the second end cover 74 and the partition plate 4 limited by the light shield plate 3 are synchronously rotated and unfolded, the light sources at both sides of the lamp body 1 are shielded, so that the light width range of the lamp body 1 is adjusted; when the light shield plates 3 and the partition plates 4 at both sides of the lamp frame 2 are unfolded and folded at the bottom of the lamp body 1, the light is completely shielded. When the support rod 71 rotates, the second elastic sheet 78 is elastically deformed, and after the adjustment is completed, the second elastic sheet 78 is clamped in the slot of the gear ring 79 to limit, so that the stability of the support rod 71 and the light shield plate 3 is kept, and the first elastic sheet 42 corresponding to the partition plate 4 is also clamped in the gear slot 12 to keep the stability of the partition plate 4.

[0046] The present application can control the light range in the length direction of the lamp body 1 by controlling the spring pin 5 in different opening positions, and can shield the light at one end of the lamp body 1 or at both ends of the lamp body 1.

[0047] Specifically: by pushing the top assembly 6 control corresponding spring pin 5 adjacent two groups of light shield 3 between the release limit, rotate the support rod 71 closer to the spring pin 5, until the end of the first end cover 73 and the second end cover 74 and the light shield 3 unfolded and folded below the lamp body 1, the baffle 4 due to the first spring 42 and the limit between the tooth groove 12 remains stable, similarly, by pushing the top assembly 6 control baffle 4 the other side of the adjacent light shield 3 release limit, and rotate the end of the support rod 71, so that the end of the first end cover 73 and the second end cover 74 and the light shield 3 rotate and fold below the lamp body 1, so as to realize the length direction of the lamp body 1 light range adjustment. Therefore, the present application can realize the width of the light of the lamp remains unchanged, the length of the light range is adjusted, the length of the light can also be kept unchanged, the width of the light range is adjusted, and the adjustment of the present application is from both sides to the middle adjustment mode, when the light width is adjusted, the lamp beads distributed on both sides of the lamp body 1 can still provide light to the outside through the light illumination angle, keeping a high luminous flux; and the light angle adjustment of the present application is double-sided synchronous adjustment, which significantly improves the adjustment efficiency.

[0048] On the basis of the above adjustment, the present application can also realize the adjustment of the shortening of the light length and the shortening of the light width, and the adjustment of the light range shortening and the lamp holder 2 adjusting the light angle.

[0049] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
