[0002] Currently, LED surgical lights are designed using a decentralized arrangement of various individual lenses and light sources, which results in a cluttered layout of the surgical light's optical modules and an unattractive overall appearance.

[0003] Therefore, the existing technology still needs to be improved and enhanced. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a surgical lamp with an integrated optical module.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A surgical light with an integrated optical module includes multiple lens modules. Each lens module includes several lens units, each lens unit including a first lens and a second lens. Light passing through the first lens forms a circular spot on the illumination surface, and light passing through the second lens also forms a circular spot on the illumination surface. The spot area of ​​the second lens is larger than that of the first lens. The optical axes of the first lens and the second lens are parallel. The first lens and the second lens are fixedly connected. The spots of the corresponding lens units are superimposed to form the spot of the corresponding lens module. The spots of multiple lens modules are superimposed to form the surgical field spot.

[0007] Furthermore, in the surgical lamp of the integrated optical module, one lens module is a positive module with its lens units arranged in a circumferential array. The first lens of its lens unit faces inward and the second lens faces outward. The light spot of its first lens on the irradiation surface is located at the center of the irradiation surface.

[0008] Furthermore, in the surgical lamp of the integrated optical module, one lens module is a reverse module, with its lens units arranged in a circumferential array. The first lens of its lens unit faces outward and the second lens faces inward, pointing from the first lens to the second lens towards the center of the array. The light spot of its second lens on the irradiation surface is located at the center of the irradiation surface.

[0009] Furthermore, the surgical lamp with the integrated optical module includes multiple lens modules, wherein the positive module and the negative module form one set.

[0010] Furthermore, in the surgical lamp with the integrated optical module, the positive modules have a staggered relative rotation angle θ between them, θ = 360º / (N1) (n1), where N1 is the number of lens units in the positive module and n1 is the number of positive modules.

[0011] Furthermore, in the surgical lamp with the integrated optical module, the anti-module has a misaligned relative rotation angle θ between the anti-modules, θ = 360º / (N1) (n1), where N1 is the number of lens units in the anti-module and n1 is the number of anti-modules.

[0012] Furthermore, in the surgical lamp with the integrated optical module, the lens module is arranged in a four-dimensional circular array spaced at 90° intervals.

[0013] Furthermore, in the surgical lamp with the integrated optical module, the difference between the spot diameter of the second lens on the irradiation surface and the spot diameter of the first lens on the irradiation surface is not less than 100 mm.

[0014] Furthermore, in the surgical lamp of the integrated optical module, the sum of the distance between the optical axis of the first lens and the optical axis of the second lens and the light spot radius of the second lens on the irradiation surface is greater than 150mm.

[0015] Furthermore, in the surgical lamp with the integrated optical module, the first lens and the second lens have the same aperture and height, and the first lens and the second lens are integrally formed.

[0016] Compared to existing technologies, this invention provides a surgical lamp with an integrated optical module, comprising multiple lens modules. Each lens module includes several lens units, each lens unit comprising a first lens and a second lens. Light passing through the first lens forms a circular spot on the illumination surface, as does light passing through the second lens. The spot area of ​​the second lens is larger than that of the first lens. The optical axes of the first and second lenses are parallel. The first and second lenses are fixedly connected. The spots of corresponding lens units are superimposed to form the spot of the corresponding lens module. The spots of multiple lens modules are superimposed to form the surgical field spot. This invention integrates two spot sizes into one unit, including a large circular spot and a small circular spot, achieving different types of surgical field spots through the combination of these two lenses.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0039] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0040] like Figure 1As shown, this invention provides a surgical lamp with an integrated optical module, including multiple lens modules. Each lens module includes several lens units, each lens unit comprising a first lens 110 and a second lens 120. Light passing through the first lens 110 forms a circular spot on the illumination surface, as does light passing through the second lens 120. The spot area of ​​the second lens 120 is larger than that of the first lens 110. The optical axes of the first lens 110 and the second lens 120 are parallel. The first lens 110 and the second lens 120 are fixedly connected. The spots of corresponding lens units are superimposed to form the spot of the corresponding lens module. The spots of multiple lens modules are superimposed to form the surgical field spot. This invention integrates two lens sizes into one unit, including a large circular spot and a small circular spot, achieving different types of surgical field spots through the combination of these two lenses.

[0041] Specifically, the difference between the spot diameter of the second lens 120 on the irradiation surface and the spot diameter of the first lens 110 on the irradiation surface is not less than 100 mm. The sum of the distance between the optical axis of the first lens 110 and the optical axis of the second lens 120 and the spot radius of the second lens 120 on the irradiation surface is greater than 150 mm. The first lens 110 and the second lens 120 have the same aperture and height, and are integrally formed. The irradiation surface of the surgical lamp generally refers to the irradiation surface at a position 1000 mm away from the surgical lamp.

[0042] like Figures 2-7 As shown, this embodiment integrates lenses of various spot sizes, including a large circular spot and a small circular spot, with a distance d0 between the two lenses. The two lenses are designed to be joined together after the optical axes are placed parallel, and then integrally injection molded. The first lens 110 is a small circular spot lens, and the second lens 120 is a large circular spot lens. The aperture and height of the two lenses are identical. Figure 7 The cross-sectional view of the first lens 110 / second lens 120 shows that all surfaces S1, S2, S3, S4, and S5 are optically designed control surfaces. S1 and S5 control light energy within approximately 9 degrees, and these two surfaces are even-order aspherical surfaces, controlling this portion of light energy through transmission. Light energy from 9 to 90 degrees is jointly controlled by S2, S3, and S4. Specifically, after one transmission control by the aspherical surface of S2, it is controlled by two total internal reflections by the surface of S3, and finally by the transmission control by the surface of S4. This design of the TIR can maximize the use of all surface shapes to control the collimation of light output. While meeting optical performance requirements, the concave surface of the S4 surface also optimizes the weight reduction of the TIR lens. To obtain large or small light spots, the desired spot size can be obtained by controlling the surface shape type or related parameters of the surfaces of S1, S2, S3, S4, and S5.

[0043] The two integrated lenses have parallel optical axes and a distance of d0. At the same time, the distance between the two light spots on the irradiation surface 1000mm away is also d0. The size of d0 is not simply defined by its size. It is related to the size of the two circular light spots. Usually, the maximum size of the surgical field light spot must be more than 300mm. If the radius of the small light spot is r1 and the radius of the large light spot is r2, their size relationship is: r2 + d0 > 150mm.

[0044] Further, in the surgical lamp of the integrated optical module, one lens module is a positive module, with its lens units arranged in a circular array. The first lens 110 of each lens unit faces inward, and the second lens 120 faces outward. The light from the second lens 120 to the first lens 110 points to the center of the array, and the light spot of the first lens 110 on the illumination surface is located at the center of the illumination surface. Further, in the surgical lamp of the integrated optical module, one lens module is a negative module, with its lens units arranged in a circular array. The first lens 110 of each lens unit faces outward, and the second lens 120 faces inward. The light from the first lens 110 to the second lens 120 points to the center of the array, and the light spot of the second lens 120 on the illumination surface is located at the center of the illumination surface. Further, the surgical lamp of the integrated optical module includes multiple lens modules, with the positive module and the negative module forming one group. Further, in the surgical lamp of the integrated optical module, the positive modules have a staggered relative rotation angle θ between them, θ = 360º / (N1). (n1), where N1 is the number of lens units in the positive module, and n1 is the number of positive modules. Further, in the surgical lamp of the integrated optical module, the reverse modules have a staggered relative rotation angle θ, where θ = 360º / (N1) (n1), where N1 is the number of lens units in the anti-module and n1 is the number of anti-modules. Further, in the surgical lamp of the integrated optical module, the lens module is arranged in a four-element, 90° angularly spaced circular array.

[0045] Specifically, such as Figure 8-11 As shown, in this embodiment, two lenses are connected together. The first lens 110 faces inward. The small light spot is centered at the irradiation point 1000mm away. The distance between the irradiation points of the large light spot is d0. With the first lens 110 facing inward, the lens unit is offset outward by a certain distance and deflected by an angle so that the landing point of the small light spot is the center of the plane 1000mm away. Six units are rotated and arrayed on a circle with a diameter of D to form a positive module.

[0046] like Figure 12-15As shown, the second lens 120 faces inward, and the large light spot is centered at the irradiation point 1000mm away. The distance between the irradiation points of the small light spot is d0. With the large light spot lens facing inward, the integrated lens is offset outward by a certain distance and deflected by an angle so that the large light spot falls at the center of the plane 1000mm away. Six units are rotated and arrayed on a circle with a diameter of D to form an anti-module.

[0047] like Figure 16-20 As shown, four lens modules (two positive modules and two negative modules) are arranged in a 90-degree angle array along a circle with a diameter of D0, and the light spot center of the lens module is directed towards the center of the overall surgical field light spot at a distance of 1000mm. Two modules of the same type are offset relative to each other by 30 degrees (360º / (6 2) Rotation results in 12 equidistantly superimposed circular light spots on a circle with radius d0. The light spots at 45 degrees and 135 degrees are positive modules. The light spots of two positive modules are combined to obtain a uniform small light spot combined with the center. Similarly, the light spots at 225 degrees and 315 degrees are negative modules. The light spots at 225 degrees and 315 degrees can also obtain a uniform large light spot combined with the center. Finally, four types of combined light spots with diameters of D1, D2, D3 and D4 can be obtained.

[0048] In this embodiment, the first lens 110 faces inward, with the small light spot centered on the illumination point on the projection surface at a distance of 1000mm. The spacing between the illumination points of the large light spot is d0. The lens unit is rotated and arrayed with 6 units along the diameter D of the circle, resulting in the superposition of six small light spots at the center on the 1000mm illumination surface. Similarly, the second lens 120 faces inward, with the large light spot centered on the illumination point on the projection surface at a distance of 1000mm. The spacing between the illumination points of the small light spots is d0. The lens unit is rotated and arrayed with 6 units along the diameter D of the circle, resulting in the superposition of six large light spots at the center on the 1000mm illumination surface. Using two sets of positive and negative modules, a total of four lens modules are arrayed at 90-degree intervals along the circumference of diameter D0. The center of the light spot of each regional module is offset towards the center of the overall surgical field light spot at a distance of 1000mm. In addition, two modules of the same type are relatively offset by 30 (360º / (6 2) Rotating the light spot at a 36-degree angle results in 12 equidistant superimposed circular spots on a circle with radius d0. As shown in the figure, the 45-degree and 135-degree positions represent the same area combination. Combining these two types of spots yields a uniform small spot illuminating the center. Similarly, the 225-degree and 315-degree positions also produce a uniform large spot illuminating the center. Finally, the two lens modules and their corresponding overall staggered arrangement can obtain uniform spots with four diameter combinations: D1, D2, D3, and D4. By adjusting the intensity ratio of these four combinations, different sizes of surgical field spots can be obtained. Adjusting the current also allows for adjustment of the surgical field spot illumination. This invention features a modular and integrated optical element design, where one optical module has multiple surgical field spot functions, and the overall device is more integrated and aesthetically pleasing. Lens integration, modular array lens regions, and the superposition of multiple region modules optimize optical performance. The symmetrical design of the positioning structure at both ends of the two-in-one integrated lens enables all structural and electronic components of the four regional modules of the overall structure to be shared. The two regional functions can be realized simply by reversing the assembly of the integrated lens, achieving a highly integrated design in terms of appearance, function, parts procurement, and production operation.

[0049] In summary, this invention utilizes two lens modules and a corresponding overall staggered arrangement to obtain uniform light spots with four diameter combinations: D1, D2, D3, and D4. By adjusting the intensity ratio of these four combined light spots, surgical field light spots of different sizes can be obtained. Adjusting the current magnitude can also adjust the illumination of the surgical field light spots. This invention features a modular and integrated optical element design, with one optical module possessing multiple surgical field light spot functions. Furthermore, the overall device is integrated and aesthetically pleasing. Lens integration is achieved through modular array lens areas and the superposition of multiple area modules, resulting in optimized optical performance. The symmetrical design of the positioning structure at both ends of the two-in-one integrated lens allows all structural and electronic components of the four area modules to be shared. The two area functions can be achieved simply by reversing the assembly of the integrated lens, realizing a highly integrated design encompassing appearance, function, component procurement, and production operations.
