However, the light emitting components in the above prior art are bulbs that filter out infrared light through a filter to reduce heat effects. Although the improved shadowless lamp uses LED, which is a cold light source, it still generates some heat under high power and long-term use. The excess heat of the LED light emitting element causes a small air convection near it, which interferes with the laminar flow.

[0015] The following embodiments further illustrate the content of the present application, but should not be understood as limiting the present application. Modifications or replacements of the method, steps or conditions of the present application, without departing from the spirit and essence of the present application, all belong to the scope of the present application.

[0016] As shown in some embodiments Figures 1-3 , including Figure 1The device includes a main lamp body 1 and a suspension arm 2. The main lamp body 1 includes a hollow lamp panel 10, which comprises a grid structure made of hollow carbon fiber and a connector 12. Each grid point 11 of the grid structure is provided with an LED point light source 3. The connector 12 is fixed to the top or edge of the lamp panel 10. The suspension arm 2 is fixedly connected to the connector 12. The wires of the LED point light sources 3 are embedded in the cavity of the grid structure 11. Figure 1 (Not shown).

[0017] The LED point light source 3 includes, for example: Figure 2 The light source includes a focusing tube 30 and LED beads 31 disposed at the bottom of the focusing tube 30, the bottom of which is movably disposed at the grid points of the grid structure. Laminar airflow passes through the hollowed-out portions of the grid structure, and the hollowed-out light panel does not interfere with the vertical laminar flow.

[0018] The array of LED point light sources projects light in an interlaced manner, eliminating shadows by utilizing the principle of optical path interference, resulting in a shadow retention rate of <3% (compared to approximately 10% for conventional lamps). Other embodiments include at least 12 micro LED chips.

[0019] Figures 1-3 In an embodiment, the grid structure includes shapes such as Figure 2 The dome-shaped grid structure and shape like Figure 3 A horizontal grid structure. In a more preferred embodiment, the surface curvature is optimized based on the above structure. Through computational fluid dynamics simulation (CFD), a grid structure with a curvature radius of 100-120cm is selected for the lamp panel with a diameter of 60-80cm to guide the airflow to flow smoothly and avoid airflow separation to form vortices.

[0020] Based on the above embodiments, some implementations, for example Figure 4 The grid structure has a focusing tube bracket 4 fixed at each grid point. Each focusing tube bracket has a support leg on each side of the focusing tube, and each support leg is fixed to the grid frame. The focusing tube 30, hinged to the support leg, forms different angles with the horizontal plane of the grid structure, allowing the LED beads 31 to have different light projection angles. The light projection angle of the focusing tube, fixed to the edge of the lamp panel, is offset towards the central axis of the lamp panel, causing the multiple LED beads to form a columnar light spot with a height of 30-60cm.

[0021] In some of the above embodiments, the lamp body surface is coated with a photocatalytic layer for decomposing organic pollutants during the ultraviolet disinfection cycle in the operating room.

[0022] The above embodiment includes a mother lamp with different power and at least one daughter lamp.

[0023] In the above embodiments, the connecting component is a telescopic ball joint.

[0024] Other embodiments, in Figures 1-2 Each of the LED point light sources is provided with a variable-focus Fresnel lens focuser based on the structure, which can adopt a variable-focus liquid lens based on a Fresnel lens as disclosed in patent CN 208044108 U, which is filled with two layers of liquid in the groove, one of which is a polar liquid layer, and the other is a non-polar liquid layer. The polar liquid layer can change the curvature of the contact surface between the two liquids under the action of an electric field. In use, by applying an electric field to the polar liquid in the groove that can change the refractive index under the action of an electric field, the curvature of the contact surface between the two liquid layers in the groove can be changed, thereby realizing the adjustment of the focal length of the lens.

[0025] In Figures 1-2 On the basis of any of the structures shown, the preferred embodiment is to coat the surface of the lamp body with a photocatalyst layer (nanometer titanium dioxide photocatalyst coating) for decomposing organic pollutants during the ultraviolet disinfection cycle in the operating room.

[0026] Other embodiments, in Figures 1-2 On the basis of any of the structures shown, a micro-structured honeycomb light uniformity plate (thickness 2 mm, aperture 0.5 mm) is also provided outside the light collector. The micro-structured honeycomb light uniformity plate diffuses the point light source into a surface light source, making the illuminance uniformity (maximum / minimum) ≤1.2:1.

[0027] Some of the above embodiments divide the main lamp body into several independent power supply areas according to the dispersed distribution of LEDs, and each LED module is independently powered. In the event of any circuit failure, the adjacent area compensation is automatically isolated and started.

[0028] Further embodiments, dual redundant power supply is adopted: main power supply (24V DC) and standby super capacitor (energy storage 1800J), which can maintain full power operation for 5 minutes when power is off.

[0029] The technical solution proposed in this application can be applied to the following surgical scenarios:

[0030] Neurosurgery: Select LED light source as 6000K cool white light, adjust the focus to use small spot mode, and enhance the contrast of fine structures of brain tissue.

[0031] Laparoscopic assisted open surgery: Start "double-zone lighting", focus on the incision, and supplement the light in the periphery of the laparoscope screen reflection area.
