[0041] Example:

[0042] like Figures 1 to 14 As shown, in this embodiment, a surgical lamp with multiple lighting systems includes a first lighting system 1 and a second lighting system 2 arranged on the same lamp panel 3;

[0043] The first lighting system 1 includes 2N first optical modules 11 and 2N second optical modules 12 (N is a natural number and N≥4), and the first optical modules 11 and the second optical modules 12 are arranged in an array evenly spaced at equal angles on the same circumference or different circumferences around the center of the lamp panel 3;

[0044] The first optical module 11 and the second optical module 12 each include three integrally formed illumination units, each illumination unit can form an elliptical and / or circular basic light spot on a surgical field area at a preset distance from the light emitting surface, each basic light spot is distributed in a circle with equal angles around the center of the surgical field area, and adjacent basic light spots at least partially overlap to form a first illumination light spot;

[0045] The second lighting system 2 is arranged inside or outside the first lighting system 1, and forms a second lighting spot on the surgical field area at a preset distance from the light emitting surface. The color temperature and / or wavelength of the second lighting spot is different from that of the first lighting spot.

[0046] In this embodiment, the first lighting system 1 integrates at least 8 first optical modules 11 and 8 second optical modules 12, each of the first optical modules 11 and each of the second optical modules 12 is a three-in-one optical module, and a sufficient number of multi-point light sources can form basic light spots of different positions and various shapes in the surgical field area, and the overlap of each basic light spot can form a uniformly distributed and diverse first lighting light spot. The first lighting system 1 is distributed at equal angles on the circumference, and the second lighting system 2 is arranged at the inner or outer periphery of the first lighting system 1. The color temperature and / or wavelength of the second lighting system 2 are different from the first lighting light spot. The first lighting system 1 provides a sufficient number of lighting light sources, and the second lighting system 2 can provide an environmental lighting function different from the first lighting system 1, and provide environmental lighting in laparoscopic surgery, endoscopic surgery or other surgical scenarios.

[0047] Specifically, each illumination unit can be equipped with different types of light-transmitting plates to change the shape of the light spot formed in the surgical field area, thereby obtaining basic light spots of different sizes and shapes, such as changing the size of the light spot by assembling a light-transmitting plate with a concave-convex surface, changing the shape of the basic light spot from a circle to an ellipse by assembling a light-transmitting plate with a striped surface, and so on.

[0048] Furthermore, if Figure 2 and 3 As shown, the second lighting system 2 includes at least one double-lens module 21 , and the perpendicular bisector of the center line of two lenses in each double-lens module 21 passes through the center of the lamp panel 3 .

[0049] Specifically, Figure 4 As shown, the dual lens module 21 includes two TIR lenses, the TIR lenses are scaly TIR lenses, and the two TIR lenses are integrally formed to achieve a solid light spot effect. Preferably, the second lighting system 2 can be provided with a dual lens module 21. When multiple dual lens modules 21 are provided in the second lighting system 2, each dual lens module 21 can be symmetrically or asymmetrically arranged around the center of the lamp panel 3.

[0050] like Figure 2 and 3As shown, on the lamp panel 3, the inner periphery of each first lighting system 1 is the central area of ​​the lamp panel 3, and the outer periphery of each second lighting system 2 is the peripheral area of ​​the lamp panel 3. The perpendicular bisector of the center line of the two lenses in the second lighting system 2 passes through the center of the lamp panel 3, and the second lighting system 2 is arranged along the radial direction of the central area, which can save space in the central area and the peripheral area of ​​the lamp panel 3, and reserve a larger position for the first lighting system 1, so that the first lighting system 1 can be arranged with more point light sources.

[0051] Furthermore, if Figure 2 As shown, the first optical modules 11 are arranged at equal angles on a circumference, the second optical modules 12 are arranged at equal angles on another circumference outside the circumference of the equal angle array of the first optical modules 11, and a single dual lens module 21 is arranged between two adjacent second optical modules 12.

[0052] When the first optical modules 11 and the second optical modules 12 are arranged in an array at equal angles and evenly spaced on different circumferences around the center of the lamp panel 3 , the dual lens module 21 is placed between adjacent second optical modules 12 , which can effectively utilize the space of the lamp panel 3 .

[0053] In other embodiments, Figure 1 and Figure 5 As shown, the second lighting system 2 includes a plurality of LED lamp beads 22, any LED lamp bead 22 is one of the three primary color LED lamp beads 22, and the plurality of LED lamp beads 22 are arranged in an equiangular array on a circle.

[0054] The three-primary color LED lamp bead 22 refers to the LED lamp bead 22 of the three colors of red (R), green (G), and blue (B), also known as RGBLED. The three-primary color LED lamp bead 22 has light-emitting elements of three basic colors, and can produce a variety of different colors of light by mixing these three basic colors to different degrees. By adjusting the energy proportion of the three light-emitting elements of red (R), green (G), and blue (B), a variety of color conversions can be achieved, and the wavelength of the second illumination spot on the surgical field area can be changed.

[0055] The second lighting system 2 can be configured as a plurality of LED lamp beads 22 and / or a dual lens module 21 , and the plurality of LED lamp beads 22 and the dual lens module 21 can individually adjust the color temperature / wavelength of the second lighting spot formed thereby.

[0056] Furthermore, if Figure 5 As shown, the second lighting system 2 also includes a light mixing plate 23, which is in a circular shape and whose center overlaps with the center of the lamp panel 3. Multiple LED lamp beads 22 are arranged in an equal angle array on the light mixing plate 23, and the light mixing plate 23 is arranged on the light emitting surface side of the LED lamp beads 22.

[0057] The LED lamp beads 22 are connected to the lamp panel 3 in a circular trajectory array. After being mixed by the light mixing plate 23, the LED lamp beads 22 in the circular trajectory array can present a uniform lighting effect. By adjusting the energy proportion of the three light-emitting elements of red (R), green (G), and blue (B), a variety of color changes can be achieved, and the wavelength of the third illumination spot on the surgical field area can be changed.

[0058] Furthermore, if Fig.14 As shown, the second illumination light spot is circular, and the center of the second illumination light spot overlaps with the center of the first illumination light spot.

[0059] The center of the first illumination spot is located at the center of the surgical field area, and the center of the second illumination spot is also located at the center of the surgical field area. When the first illumination system 1 and the second illumination system 2 are turned on at the same time, the first illumination spot and the second illumination spot can be evenly superimposed, and the second illumination spot can provide ambient lighting.

[0060] Further, the diameter of the second illumination spot is greater than or equal to the diameter of the first illumination spot.

[0061] It should be known that the first lighting system 1 and the second lighting system 2 can be turned on at the same time or separately.

[0062] When the first lighting system 1 and the second lighting system 2 are turned on at the same time, the second lighting system 2 can serve as an auxiliary lighting system for the first lighting system 1, and can provide a second lighting spot with a different color temperature / wavelength from the first lighting spot as ambient lighting, thereby reducing visual fatigue caused by long-term staring at a single light spot during surgery. The second lighting system 2 can be turned on alone to provide ambient lighting for laparoscopic surgery and non-external incision surgery.

[0063] Furthermore, if Fig.14 As shown, the diameter of the first illumination spot is 600 mm to 700 mm; the diameter of the second illumination spot is 600 mm to 800 mm.

[0064] In this embodiment, if Figures 1 to 3 As shown, the first optical module 11 and the second optical module 12 each include an integrally formed first illumination unit, a second illumination unit and a third illumination unit;

[0065] The light emitting surfaces of the first illumination unit, the second illumination unit and the third illumination unit are located in the same plane, and the distance from the center of the first illumination unit to the center of the second illumination unit is equal to the distance from the first illumination unit to the center of the third illumination unit;

[0066] The first illumination unit in the first optical module 11 is disposed away from the center point of the lamp panel 3 ; the first illumination unit in the second optical module 12 is disposed close to the center point of the lamp panel 3 .

[0067] The first optical module 11 and the second optical module 12 are both used to form a first light spot, a second light spot and a third light spot on the surgical field area, the centers of the second light spot and the third light spot overlap and are located at the center of the surgical field area; the first light spot is distributed in an equiangular array around the center of the surgical field area;

[0068] The first light spot 111a, the second light spot 112a and the third light spot 113a of the first optical module 11 are circular, and the diameters of the second light spot 112a and the third light spot 113a are different;

[0069] The first light spot 121a and the second light spot 122a formed by the second optical module 12 are circular, and the third light spot 123a is elliptical; the third light spot 123a formed by the second optical modules 12 arranged opposite to each other on the circumference is symmetrical about the center of the surgical field area.

[0070] Specifically, Figure 6 As shown, a first rectangular coordinate system is established with the light emitting surfaces of the first illumination unit 111, the second illumination unit 112 and the third illumination unit 113 of the first optical module 11 as references, and the preset distance between the first illumination unit 111, the second illumination unit 112 and the third illumination unit 113 is D=1000mm (that is, the distance between the light emitting surface and the plane where the surgical field area is located is D=1000mm), and the line connecting the center point of the second illumination unit 112 to the center point of the third illumination unit 113 is used as the first rectangular coordinate system. The x-axis of the rectangular coordinate system is as follows: the straight line perpendicular to the midpoint of the line connecting the centers of the second illumination unit 112 and the third illumination unit 113 is used as the y-axis of the first rectangular coordinate system; the midpoint of the line connecting the centers of the second illumination unit 112 and the third illumination unit 113 is used as the first origin (0, 0); the coordinates of the center point of the first illumination unit 111 are (0, d1); the coordinates of the center point of the second illumination unit 112 are (-d2, 0); and the coordinates of the center point of the third illumination unit 113 are (d2, 0).

[0071] After the geometric distribution relationship among the first illumination unit 111, the second illumination unit 112 and the third illumination unit 113 is determined, the deflection angle of each illumination unit can be calculated according to the distance from the light emitting surface of the first illumination unit 111, the second illumination unit 112 and the third illumination unit 113 to the plane of the surgical field area, and the position of the center C of the surgical field area that each circular light spot needs to illuminate.

[0072] The geometrical distribution relationship among the first illumination unit 121 , the second illumination unit 122 and the third illumination unit 123 in the second optical module 12 is the same as that of the first optical module 11 , and will not be described in detail herein.

[0073] As an example, Figure 7This is a schematic diagram of the light S irradiation of the first illumination unit 111, the second illumination unit 112 and the third illumination unit 113 in the first optical module 11 when the preset distance is D=1000mm. The center of the first circular light spot needs to coincide with the center C of the surgical field area. The preset distance between the first illumination unit 111, the second illumination unit 112 and the third illumination unit 113 is D=1000mm. The multiple first illumination units 111 are arranged at equal angles on an arc with a radius of R1. The deflection angle of each illumination unit can be calculated based on the above information.

[0074] In addition, the preset distance D of the first illumination unit, the second illumination unit and the third illumination unit can be changed and is not limited to D=1000mm. Those skilled in the art can calculate and set the deflection angle of each illumination unit accordingly according to the geometric distribution relationship provided by the first illumination unit 111, the second illumination unit 112 and the third illumination unit 113 of the first optical module 11 according to different usage scenario requirements and the distance D between the light emitting surface and the illumination surface to manufacture the required lighting device.

[0075] A second rectangular coordinate system is established with the illumination surfaces of the first illumination unit 111, the second illumination unit 112 and the third illumination unit 113 of the first optical module 11 as references, the preset distance between the first illumination unit 111, the second illumination unit 112 and the third illumination unit 113 is D=1000mm, and the first light spot 111a, the second light spot 112a and the third light spot 113a formed by the first optical module 11 are located on the illumination surface.

[0076] A perpendicular line passing through the center point of the second light spot 112a and connecting the center points of the first light spot 111a and the second light spot 112a is used as the x-axis of the second rectangular coordinate system, and a line connecting the center points of the first light spot 111a and the second light spot 112a is used as the y-axis of the second rectangular coordinate system. The coordinates of the center point of the first light spot 111a are (0, d1'), the coordinates of the center point of the second light spot 112a are (0, 0), and the coordinates of the center point of the third light spot 113a are (0, 0).

[0077] like Fig. 9 The figure shows a schematic diagram of the superposition of three light spots formed by the first optical module 11 of the lighting device in the surgical field area. The first optical module 11 in the lighting device forms a superposition effect of three light spots in the surgical field area, forming three superimposed light spots with diameters of D1, D2 and D3. The types of superimposed light spots are rich, so that the superimposed light spots are clearly displayed when the lighting device illuminates the surgical field area. The size of the superimposed light spots can be adjusted by controlling the intensities of the three superimposed light spots.

[0078] like Fig.12As shown, in some embodiments, a third rectangular coordinate system is established with the illumination surfaces of the first illumination unit 121, the second illumination unit 122 and the third illumination unit 123 of the second optical module 12 as a reference, and the first light spot 121a, the second light spot 122a and the third light spot 123a formed by the second optical module 12 are located on the illumination surface.

[0079] A perpendicular line passing through the center point of the second light spot 122a and connecting the center points of the first light spot 121a and the second light spot 122a is used as the x-axis of the second rectangular coordinate system, and a line connecting the center points of the first light spot 121a and the second light spot 122a is used as the y-axis of the second rectangular coordinate system. The coordinates of the center point of the first light spot 121a are (0, d1'), the coordinates of the center point of the second light spot 122a are (0, 0), and the coordinates of the center point of the third light spot 123a are (0, 0).

[0080] In this embodiment, d1 and d1' are equal. In other embodiments, d1 and d1' may be different.

[0081] like Fig.10 The figure shows a schematic diagram of the superposition of three light spots formed by the second optical module 12 of the lighting device on the surgical field area. The second optical module 12 in the lighting device forms a superposition effect of three light spots on the surgical field area, forming three superimposed light spots with diameters of D4, D5 and D6. Fig.13 As shown, the first optical module 11 and the second optical module 12 form a total of six light spots in the surgical field area, and their diameters are D1, D2, D3, D4, D5 and D6 respectively. The intensity ratios of these six light spots are controlled to achieve overall size adjustment of the first illumination spot, and the current input into the illumination device is controlled to achieve overall illumination adjustment of the first illumination spot.

[0082] Among them, Figure 1 As shown, the second optical modules 12 arranged relatively on the circumference are driven separately to form two elliptical third light spots 123a on the surgical field area, and the two third light spots 123a can overlap to form a large elliptical surgical field light spot effect. By selecting the second optical modules 12 arranged relatively on different positions of the circumference and adjusting the illumination of the third light spots 123a formed therefrom, the angle conversion of the elliptical surgical field light spot can be achieved.

[0083] The surgical lamp in the utility model has a first lighting system 1 and a second lighting system 2. The first lighting system 1 includes a three-in-one optical module with two arrangement modes, which can form six light spots with adjustable proportions and different diameters in the surgical field area, and its illumination distribution is uniform and the light spot angle is adjustable. The second lighting system 2 is arranged at the inner or outer periphery of the first lighting system 1. The second lighting system 2 and the first lighting system 1 are reasonably distributed. The second lighting system 2 provides sufficient distribution positions for the first lighting system 1 in the limited space of the lamp panel 3, so that the surgical lamp can integrate two light spot functions, so as to be suitable for more surgical scenes such as laparoscopic surgery and non-external incision surgery.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
