[0018] The present patent can be further clearly understood through the following specific embodiments given, but they do not limit the present patent.

[0019] Embodiment 1: A shadowless lighting assembly, comprising: a shadowless lamp main body 1 installed at the bottom of the base 2, a bearing seat 304 is fixedly installed at the top of the base 2 in a symmetrical manner, and a connecting arm 302 with a rotating shaft 303 is arranged between the two bearing seats 304. One end of the connecting arm 302 away from the bearing seat 304 is fixedly installed with an inclined small shadowless lamp 301. The rotating shaft 303 is rotatably connected to the bearing seat 304 through a support shaft 310. A servo motor 307 for driving the support shaft 310 to rotate is arranged on one side of the bearing seat 304;

[0020] By supporting the small shadowless lamp on one side of the shadowless lamp main body through the connecting arm, the unilluminated position of the shadowless lamp main body can be compensated. Compared with adjusting the position of the shadowless lamp main body according to the surgical position, directly lowering the small shadowless lamp is more convenient and has a better illumination effect. At the same time, by starting the servo motor, the small shadowless lamp can be driven to flip above the chassis for storage through the meshing transmission of the first gear and the second gear, avoiding manual contact and making it easier to maintain the sterility of the environment and equipment. At the same time, during the rotation of the small shadowless lamp, the damping sleeve restricts the rotating shaft, improving the stability of the small shadowless lamp during rotation.

[0021] A first gear 305 is sleeved on the support shaft 310 close to the servo motor 307.

[0022] A second gear 306 meshed with the first gear 305 is fixedly installed on the output shaft of the servo motor 307.

[0023] A chassis 308 is fixedly installed at the top of the base 2.

[0024] A damping sleeve 309 is arranged between the rotating shaft 303 and the base 2.

[0025] Embodiment 2: A shadowless lighting assembly, comprising: a shadowless lamp body 1 installed at the bottom of a base 2, wherein a bearing seat 304 is fixedly installed at the top of the base 2 symmetrically, and a connecting arm 302 with a rotating shaft 303 is arranged between the two bearing seats 304. One end of the connecting arm 302 away from the bearing seat 304 is fixedly installed with a small shadowless lamp 301 arranged obliquely. The rotating shaft 303 is rotatably connected to the bearing seat 304 through a support shaft 310. A servo motor 307 for driving the support shaft 310 to rotate is arranged on one side of the bearing seat 304;

[0026] The support shaft is driven by the servo motor to drive the connecting arm to rotate, so that the small shadowless lamp can be stored and used. The small shadowless lamp can be selectively used according to the actual situation, which can make up for the area not irradiated by the shadowless lamp body, reduce the irradiation blind area, and when the small shadowless lamp is stored, when the small shadowless lamp is not needed, the connecting arm drives the small shadowless lamp to rotate and store it above the base, which is beneficial to reducing the overall volume and facilitating the operation of the personnel on the shadowless lamp body.

[0027] A first gear 305 is sleeved on the support shaft 310 close to the servo motor 307.

[0028] A second gear 306 meshed with the first gear 305 is fixedly installed on the output shaft of the servo motor 307.

[0029] A chassis 308 is fixedly installed at the top of the base 2.

[0030] A damping sleeve 309 is arranged between the rotating shaft 303 and the base 2.

[0031] The servo motor 307 is arranged on the chassis 308.

[0032] The working principle is as follows:

[0033] During use, the small shadowless lamp is supported by the connecting arm on one side of the shadowless lamp body, which can make up for the position not irradiated by the shadowless lamp body. Compared with adjusting the position of the shadowless lamp body according to the surgical position, directly putting down the small shadowless lamp is more convenient and has a better irradiation effect. At the same time, when the servo motor is started, the small shadowless lamp can be driven to flip above the chassis for storage through the meshing transmission of the first gear and the second gear, avoiding manual contact and making it easier to maintain the sterility of the environment and equipment. At the same time, during the rotation of the small shadowless lamp, the rotating shaft is restricted by the damping sleeve, improving the stability of the rotation of the small shadowless lamp.

[0034] When the above-mentioned shadowless lighting component is adopted, the servo motor drives the support shaft to drive the connecting arm to rotate, so that the storage and use of the small shadowless lamp can be realized. The small shadowless lamp can be selectively used according to the actual situation, which can make up for the unilluminated area of the shadowless lamp main body and reduce the illumination blind area. Moreover, when the small shadowless lamp is not needed, by driving the connecting arm to drive the small shadowless lamp to rotate and store it above the base, it is beneficial to reduce the overall volume and facilitate the operation of the personnel on the shadowless lamp main body.
