DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0022] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application; in addition, in the description of the present application, unless otherwise specified, "multiple" means two or more.

[0023] like Figure 1 As shown, a shadowless lamp with freely adjustable illumination angle of the present application comprises a base, a column, and a shadowless lamp. The base can be designed as a fixed type or a mobile type according to common usage scenarios. In this embodiment, the base is a mobile base, and at least four universal wheels are arranged on the lower surface of the base, and the universal wheels are silent and lockable universal wheels. The column is fixedly mounted on the surface of the base, and at least two rotating arms are movably connected between the column and the shadowless lamp, and the rotating arms are rotatably hinged in turn. In this embodiment, the rotating arm comprises a first rotating arm and a second rotating arm, and the column, the first rotating arm, the second rotating arm and the shadowless lamp are all rotatably hinged in turn. Among them, one end of the first rotating arm is hinged to the top of the column through a damping universal joint, so that the first rotating arm can rotate freely around the hinge and be suspended at any angle for use, and the other end of the first rotating arm is rotatably connected to the second rotating arm through a damping shaft, which has a larger adjustable range than the traditional shadowless lamp.

[0024] The shadowless lamp consists of a lamp stand, a lampshade and a light source. The lamp stand is rotatably connected to one end of a second rotating arm through a damping shaft. The light source is fixedly installed on one side of the lamp stand. The inner surface of the lamp stand is a hemispherical concave surface. A lampshade is arranged on the outer side of the light source.

[0025] In order to facilitate the rotation of the shadowless lamp, the second rotating arm connected thereto is arranged in an arc shape, and the curvature of the second rotating arm is the same as the curvature of the lamp cover, so that the second rotating arm does not hinder the rotation of the shadowless lamp. The second rotating arm is rotatably connected to the lamp stand of the shadowless lamp through the damping rotating shaft. The shadowless lamp can rotate 360 ​​degrees around the damping rotating shaft and stay at any angle position.

[0026] In order to facilitate the switching and brightness adjustment of the shadowless lamp during the operation, it is necessary to deal with operations that require different light intensities, such as Figure 2 As shown, a shadowless lamp control panel is arranged on the side opposite to the connection between the lamp frame and the second rotating arm, and a power switch, a brightness adjustment button and a brightness display screen are arranged on the shadowless lamp control panel. The power switch, brightness adjustment button and brightness display screen of the shadowless lamp are electrically connected to an external power supply, and the brightness value of the shadowless lamp can be displayed instantly on the brightness display screen.

[0027] A handle and / or a camera device is provided on one side of the lamp stand. The handle is perpendicular to the plane direction of the shadowless lamp, so that the orientation and lighting angle of the shadowless lamp can be adjusted by holding the handle. The camera device is electrically connected to an external power supply and can record the surgical process for postoperative review or teaching.

[0028] In order to improve the utilization rate of light source and enhance the focusing effect, such as Figure 3 As shown, the light source of the shadowless lamp is a plurality of lens LED lamps, each of which can emit light radiation of the same luminous intensity to the surrounding space.

[0029] In order to facilitate the height adjustment, the height of the column is adjustable. For example, the column is a retractable lifting rod, which is vertically installed on the upper surface of the base. The height of the shadowless lamp is adjusted by raising and lowering the lifting rod.

[0030] In order to facilitate the base to be placed more conveniently at a position blocked by the foot of a bed or other objects, a clearance opening is provided on one side of the base to facilitate avoiding obstructions and make the shadowless lamp more convenient to approach the surgical area.

[0031] In summary, the shadowless lamp with freely adjustable illumination angle of the present application has a simple structure and is flexible to use. The height and angle of the shadowless lamp illumination can be easily adjusted, and the lens LED light source is more energy-efficient and has a good focusing effect. The whole is not restricted by ceiling installation or wall-mounted installation, and can be used in small operating rooms or field rescue, and can be moved to the operating room in a timely and convenient manner as needed.

[0032] It will be easily understood by those skilled in the art that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
