[0034] The lighting lamp provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and their application scenarios.

[0035] Please refer to Figures 1-9 The lighting lamp disclosed in the embodiments of the present application includes a base 100, a light source 200, a first light shielding member 300, a second light shielding member 400, and a linkage mechanism 500. Among them, the base 100 is the installation basis of the light source 200, the first light shielding member 300, the second light shielding member 400, and the linkage mechanism 500, and the base 100 can be installed on a wall; the light source 200 can be installed on the base 100, the first light shielding member 300 and the second light shielding member 400 jointly shield the light source 200 to limit the light emitting range of the light source 200; the linkage mechanism 500 is used to realize the movement of the first light shielding member 300 and the second light shielding member 400 together.

[0036] The light source 200 is connected with the base 100, and the first light shielding member 300 and the second light shielding member 400 are rotationally connected with the base 100. Optionally, the base 100 is provided with a mounting shaft, and the light source 200 is arranged on the mounting shaft, and the first light shielding member 300 and the second light shielding member 400 are rotationally connected with the mounting shaft. Further optionally, the first light shielding member 300 and the second light shielding member 400 can be sleeved on the outside of the mounting shaft, and the range corresponding to the included angle between the first light shielding member 300 and the second light shielding member 400 is the light emitting range of the light source 200. Moreover, at least part of the first light shielding member 300 and at least part of the second light shielding member 400 are respectively located on both sides of the light source 200, and the at least part of the first light shielding member 300 and the at least part of the second light shielding member 400 form the light emitting angle α of the light source 200. Optionally, the whole of the first light shielding member 300 and the whole of the second light shielding member 400 are respectively located on both sides of the light source 200, and the whole of the first light shielding member 300 and the whole of the second light shielding member 400 form the light emitting angle α, or a part of the first light shielding member 300 and a part of the second light shielding member 400 are respectively located on both sides of the light source 200, and the part of the first light shielding member 300 and the part of the second light shielding member 400 form the light emitting angle α, so that the first light shielding member 300 and the second light shielding member 400 jointly shield the light source 200 to limit the light emitting range of the light source 200 and adjust the size of the light spot.

[0037] The first light shielding member 300 is connected with the second light shielding member 400 through the linkage mechanism 500, so that the first light shielding member 300 and the second light shielding member 400 rotate in opposite directions. As shown in Figures 7-9 , the light emitting angle α changes when the first light shielding member 300 and the second light shielding member 400 rotate. Specifically, the light emitting angle α decreases when the first light shielding member 300 and the second light shielding member 400 approach each other, and the light emitting angle α increases when the first light shielding member 300 and the second light shielding member 400 move away from each other. In summary, by rotating the first light shielding member 300 and the second light shielding member 400 in opposite directions, the light emitting angle α can be changed, the light emitting range of the light source 200 can be changed, and the size of the light spot can be adjusted. Optionally, the linkage mechanism 500 can include a communication-connected telescopic member and a detection element. One end of the telescopic member can be hingedly connected with the base 100, the other end of the telescopic member is hingedly connected with the second light shielding member 400, and the detection element is used for detecting the movement of the first light shielding member 300. When the detection element detects the movement of the first light shielding member 300, the telescopic member telescopes to drive the second light shielding member 400 to rotate relative to the base 100, so as to realize the approach or movement away of the first light shielding member 300 and the second light shielding member 400 from each other.

[0038] In the embodiments of the present application, the first light shielding member 300 and the second light shielding member 400 are driven to move synchronously by the linkage mechanism 500. A user only needs to drive one of the first light shielding member 300 and the second light shielding member 400 to rotate by an external force, so that the first light shielding member 300 and the second light shielding member 400 move simultaneously, and the first light shielding member 300 and the second light shielding member 400 approach or move away from each other to change the light emission angle α formed by at least part of the first light shielding member 300 and at least part of the second light shielding member 400 on both sides of the light source 200, i.e. to adjust the light emission range of the light source 200, so as to adjust the size of the light spot. In this way, the user does not need to adjust each light shielding member separately, which is beneficial to simplify the light spot adjustment process.

[0039] In an alternative embodiment, the driving mechanism can only include the linkage rod 530, the first end of the linkage rod 530 is connected with the first light shielding member 300, and the second end of the linkage rod 530 is connected with the second light shielding member 400. The linkage rod 530 can be a telescopic rod, and the two ends of the linkage rod 530 are simultaneously elongated or shortened to realize the mutual approach or mutual movement away of the first light shielding member 300 and the second light shielding member 400.

[0040] In another embodiment, the linkage mechanism 500 includes a first housing 510, a second housing 520 and a linkage rod 530. The first housing 510 and the second housing 520 are movably connected with the base 100, and the first housing 510 and the second housing 520 jointly form a containing space containing the light source 200, the first light shielding member 300 and the second light shielding member 400. The first housing 510 is connected with the first light shielding member 300, the second housing 520 is connected with the second light shielding member 400, and the first housing 510 is connected with the second housing 520 through the linkage rod 530. When the first housing 510 moves, the first light shielding member 300 is driven to rotate in a first direction, and the second light shielding member 400 is driven to rotate in a second direction through the linkage rod 530 and the second housing 520. The first direction is opposite to the second direction, i.e. the first light shielding member 300 and the second light shielding member 400 approach or move away from each other. It should be noted that the first housing 510 or the second housing 520 is provided with an opening facing the light source 200, so that the light of the light source 200 can be emitted. In this embodiment, the first housing 510 and the second housing 520 jointly protect the components inside them, and the user's fingers do not need to be inserted into the first housing 510 or the second housing 520 to directly drive the first light shielding member 300 or the second light shielding member 400 to move. Instead, the first housing 510 or the second housing 520 can be controlled to realize the mutual approach or movement away of the first light shielding member 300 and the second light shielding member 400, which is more convenient to operate.

[0041] In one optional embodiment, the first housing 510 and the second housing 520 are rotatably connected to the base 100. The user drives the first housing 510 or the second housing 520 to rotate by external force. The first housing 510 drives the first light-shielding member 300 to rotate, and the first housing 510 drives the second housing 520 to rotate via a linkage rod 530. The second housing 520 also drives the second light-shielding member 400 to rotate. The two ends of the linkage rod 530 can extend or shorten simultaneously, and this simultaneous extension or shortening can be achieved through electrical control.

[0042] In another embodiment, the linkage mechanism 500 further includes a first connecting rod 540 and a second connecting rod 550. Both the first housing 510 and the second housing 520 are slidably connected to the base 100. The first end of the first connecting rod 540 is rotatably connected to the first light-shielding member 300, and the second end of the first connecting rod 540 is rotatably connected to the first housing 510. When the first housing 510 moves relative to the base 100 in a third direction, the first light-shielding member 300 is driven to rotate in a first direction via the first connecting rod 540. At this time, the first housing 510 and the first... The connecting rod 540 and the first light-shielding member 300 form a crank-slider mechanism; the first end of the second connecting rod 550 is rotatably connected to the second light-shielding member 400, and the second end of the second connecting rod 550 is rotatably connected to the second housing 520. When the second housing 520 moves relative to the base 100 in the fourth direction, the second light-shielding member 400 is driven to rotate in the second direction through the second connecting rod 550. At this time, the second housing 520, the second connecting rod 550, and the second light-shielding member 400 also form a crank-slider mechanism, wherein the third direction is opposite to the fourth direction.

[0043] In this embodiment, the linkage mechanism 500 uses mechanical linkage to make the first light-shielding member 300 and the second light-shielding member 400 move closer or further apart, avoiding electrical control methods and preventing the linkage mechanism 500 from failing to perform its linkage function due to electrical abnormalities such as power outages.

[0044] Optionally, the first end of the linkage rod 530 is rotatably provided with a first adapter, and the first adapter is slidable relative to the first shell 510. The second end of the linkage rod 530 is rotatably provided with a second adapter, and the second adapter is slidable relative to the second shell 520. The linkage rod 530 is rotatably connected with the base 100. Further optionally, the linkage rod 530 is provided with an axle hole. The linkage rod 530 is sleeved on the mounting shaft through the axle hole, so that the linkage rod 530 is rotatable relative to the base 100. At this time, the sliding direction of the first shell 510 and the second shell 520 is opposite by relying on the linkage rod 530. Therefore, the user drives the first shell 510 to slide relative to the base 100, and then drives the first light-shielding piece 300 to rotate through the first connecting rod 540. At the same time, the first shell 510 drives the second shell 520 to slide relative to the base 100 through the linkage rod 530, and then drives the second light-shielding piece 400 to rotate through the second connecting rod 550, so as to realize the mutual approaching or moving away of the first light-shielding piece 300 and the second light-shielding piece 400.

[0045] In an optional embodiment, the first shell 510 and the second shell 520 are both slidably connected with the base 100. The linkage rod 530 is rotatably connected with the base 100. The first end of the linkage rod 530 is slidable relative to the first shell 510 along a fifth direction. The second end of the linkage rod 530 is slidable relative to the second shell 520 along a sixth direction. The fifth direction is parallel to the sixth direction, and the fifth direction is opposite to the sixth direction. The fifth direction can be parallel to the sliding direction of the first shell 510. The sixth direction can be parallel to the sliding direction of the second shell 520. In this way, the first end of the linkage rod 530 is slidable relative to the first shell 510, and the second end of the linkage rod 530 is slidable relative to the second shell 520, so as to avoid the linkage rod 530 from being stuck during rotation.

[0046] In another embodiment, the fifth direction and the sliding direction of the first shell 510 have a preset included angle, and the sixth direction and the sliding direction of the second shell 520 have a preset included angle, i.e., the movement direction of the first end of the linkage rod 530 relative to the first shell 510 is different from the movement direction of the first shell 510 relative to the base 100, and the movement direction of the second end of the linkage rod 530 relative to the second shell 520 is different from the movement direction of the second shell 520 relative to the base 100. In this way, during the movement of the first shell 510 relative to the base 100 driven by the user, the first shell 510 can drive the linkage rod 530 to act, thereby realizing the driving of the second shell 520 by the linkage rod 530, or during the movement of the second shell 520 relative to the base 100 driven by the user, the second shell 520 can drive the linkage rod 530 to act, thereby realizing the driving of the first shell 510 by the linkage rod 530, avoiding the situation that the linkage rod 530 cannot be driven to act during the movement of the first shell 510, and also avoiding the situation that the second shell 520 cannot be driven to move when the linkage rod 530 acts, thereby ensuring the smooth progress of the linkage process.

[0047] In an optional embodiment, the first shell 510 is provided with a first sliding groove 511 extending along the fifth direction, and the second shell 520 is provided with a second sliding groove 521 extending along the sixth direction. The linkage mechanism 500 further includes a first sliding block and a second sliding block. The first end of the linkage rod 530 is rotatably connected to the first sliding block, and the first sliding block is in sliding cooperation with the first sliding groove 511. The second end of the linkage rod 530 is rotatably connected to the second sliding block, and the second sliding block is in sliding cooperation with the second sliding groove 521. Figure 6 In another embodiment, as shown in FIG. 6, the first sliding block can be replaced by a first bearing 560, and the second sliding block can be replaced by a second bearing 570, i.e., the linkage mechanism 500 further includes at least one of the first bearing 560 and the second bearing 570. The first end of the linkage rod 530 is connected to the first bearing 560, and the first bearing 560 is in sliding cooperation with the first sliding groove 511. The second end of the linkage rod 530 is connected to the second bearing 570, and the second bearing 570 is in sliding cooperation with the second sliding groove 521.

[0048] By adopting the embodiment, the first end of the linkage rod 530 can rotate relative to the first shell 510 and slide along the first sliding groove 511 through the first bearing 560, and the friction between the first bearing 560 and the first shell 510 is small, which is beneficial to the smooth sliding of the first end of the linkage rod 530 along the first sliding groove 511; similarly, the second end of the linkage rod 530 can rotate relative to the second shell 520 and slide along the second sliding groove 521 through the second bearing 570, and the friction between the second bearing 570 and the second shell 520 is small, which is beneficial to the smooth sliding of the second end of the linkage rod 530 along the second sliding groove 521, and ensures the normal linkage process of the linkage mechanism 500.

[0049] In an alternative embodiment, the first shell 510 and the second shell 520 are both in sliding connection with the base 100, and the sliding connection between the first shell 510 and the base 100 and between the second shell 520 and the base 100 can be realized by a structure in which a sliding block and a sliding rail are matched.
