[0027] Figure 1 is a perspective view showing a medical lighting device according to one embodiment of the present invention.

[0028] Referring to Figure 1, a medical lighting device 10 according to one embodiment of the present invention includes a frame 110, a light source unit 200, a forehead support unit 140, and a occipital support unit 150.

[0029] A medical lighting device 10 according to one embodiment of the present invention is characterized by its ability to easily adjust the length of each component to improve user comfort, and by having multiple light sources to ensure the user's field of view. This will be explained in more detail as follows.

[0030] Referring again to Figure 1, the frame 110 includes the main frame 111, the front frame 112, the rear frame 114, and the length adjustment section 116.

[0031] The main frame 111 is formed along the front and top surfaces of the wearer's head and extends from one end to form the front frame 112. The front frame 112 can be connected to and support the light source unit 200, the forehead support unit 140, etc., which will be described later.

[0032] The rear frame 114 is formed along the back of the wearer's head and can be connected to and support the occipital support portion 150, which will be described later. On the other hand, the rear frame 114 may also be further provided with an occipital support base 115 separate from the occipital support portion 150. Such an occipital support base 115 can play a role in providing more stable support to the back of the user's head.

[0033] Here, the main frame 111 and the rear frame 114 may be formed from separate components and joined together, or at least a part of them may be formed as a single, integrated (one-body) structure.

[0034] On the other hand, the main frame 111 may have a length adjustment section 116 for adjusting its length. The length adjustment section 116 can operate as a kind of toggle switch, and the main frame 111 may be moved or fixed relative to the rear frame 114, thereby determining whether or not the length can be adjusted. However, this is just one example, and various mechanical configurations as length adjustment mechanisms can be applied to the frame 110.

[0035] The forehead support portion 140 may be formed in the main frame 111 in an area corresponding to the user's forehead, and this forehead support portion 140 can serve to support the user's forehead. Such a forehead support portion 140 may be formed to be movable vertically relative to the frame 110. That is, the forehead support portion 140 may be formed to be retractable and / or retractable relative to the frame 110, and its position may be adjusted to suit the user. Here, various mechanical mechanisms can be applied for adjusting the position of the forehead support portion 140.

[0036] The occipital support portion 150 is coupled to one end of the rear frame 114 and can serve to support the user's occipital region. Such an occipital support portion 150 may be formed to be vertically movable relative to the frame 110. That is, the occipital support portion 150 may be formed to be retractable and / or retractable relative to the frame 110, and its position may be adjusted to suit the user. Here, various mechanical mechanisms can be applied for position adjustment of the occipital support portion 150.

[0037] Furthermore, although not shown in the drawings, a power supply unit (not shown) may be formed within the occipital support unit 150. That is, a power supply unit (not shown) for driving the light source unit 200, etc., may be further provided within the occipital support unit 150.

[0038] On the other hand, the light source unit 200 is coupled to one end of the front frame 112 extending from the main frame 111 and may include two or more lamp modules 220.

[0039] Here, two or more lamp modules 220 can be formed along the vertical direction when the user wears the medical lighting device 10, and may also be formed along the Z-axis direction, for example, as shown in the figure.

[0040] Furthermore, two or more lamp modules 220 may be positioned perpendicular to the area adjacent to the user's eyes. That is, two or more lamp modules 220 may be positioned substantially perpendicular to the straight line connecting the user's eyes.

[0041] In the case of a medical lighting device equipped with only one light source, there was a problem in that the light source would cast a shadow that obstructed the surgeon's field of view. To solve this problem, the medical lighting device 10 according to an embodiment of the present invention is characterized by being equipped with two or more lamp modules 220 so that the two light sources interact to prevent the formation of a shadow.

[0042] On the other hand, the lamp module 220 can emit light toward the subject. Here, the lamp module 220 can be any kind of light source device that can generate light, and may be an LED that can emit light in a specific wavelength band.

[0043] A handle 240 for adjusting the position of the light source unit 200 may be provided on one side of the light source unit 200. The light source unit 200 may be rotatably connected to one end of the front frame 112 via a hinge 113 in a direction aligned with the frame 110. That is, the relative angle and position of the light source unit 200 with respect to the front frame 112 can be adjusted via the handle 240, and the position of the light source unit 200 can be easily adjusted using such a handle 240 even during surgery.

[0044] In the following, the configuration and operation of the light source unit 200 in one embodiment of the present invention will be described in detail.

[0045] Figure 2 is a perspective view showing the light source unit 200 of a medical lighting device 10 according to another embodiment of the present invention. Figure 3 is an exploded perspective view of the light source unit 200 in Figure 2, and Figure 4 is an exploded perspective view of the angle adjustment unit 230 within the light source unit 200 in Figure 3. Figure 5 is a cross-sectional view illustrating the coupling structure between the fixed link member 232 and the light arm 210 in a medical lighting device 10 according to another embodiment of the present invention.

[0046] Referring to Figures 1 to 3, in a medical lighting device 10 according to another embodiment of the present invention, the light source unit 200 includes a light arm 210, a lamp module 220, an angle adjustment unit 230, a handle 240, and a frame connection unit 211.

[0047] The light arm 210 supports multiple lamp modules 220, and has a frame connection portion 211 formed at one end, which can be axially connected to the hinge portion 113 of the front frame 112. A handle 240 may also be connected to the other end.

[0048] The angle adjustment unit 230 connects the light arm 210 to multiple lamp modules 220, and can perform the function of connecting the light arm 210 and the multiple lamp modules 220 in an adjustable angle.

[0049] In a medical lighting device 10 according to one embodiment of the present invention, the angle adjustment section 230 includes a support member 231, a fixed link member 232, and an insertion link member 233, and may further include a fastening member 234, an O-ring 235, and a lamp unit holder 236.

[0050] Referring further to Figure 4, the fixed link member 232 may include a housing portion 2322 that accommodates a part of the lamp module 220 and a pair of connecting portions 2321 arranged on both sides of the housing portion 2322 and connected to the support portion 2312 via the insertion link member 233.

[0051] Here, the connecting portion 2363 of the lamp unit holder 236 may be positioned between the connecting portion 2321 and the support portion 2312. That is, when the fixed link member 232 and the lamp unit holder 236 are connected, the connecting portion 2321 is positioned coaxially with the connecting portion 2363, but it may also be positioned inside the connecting portion 2363.

[0052] The connecting portion 2321 may include a guide portion 2326 that protrudes in the thickness direction from one surface that connects with the connecting portion 2363. In this case, the guide portion 2326 may have a shape that surrounds the connecting portion 2363 in accordance with the shape of the connecting portion 2363, as shown in Figure 4. When adjusting the angle of the fixed link member 232 with respect to the lamp unit holder 236, the guide portion 2326 can perform the function of preventing rotation beyond a preset angle.

[0053] Furthermore, the connecting portion 2321 can have a connecting hole 2325 formed so as to connect with the fastening member 234 via the insertion link member 233 and the O-ring 235.

[0054] On the other hand, the insertion link member 233 may be formed as an insert nut, or it may be inserted into the coupling hole 2325 of the coupling portion 2321 and fixed in place. The insertion link member 233 can then be coupled to the connecting portion 2363 with the O-ring 235 fitted inside.

[0055] The fastening member 234 may include a handle and a male screw. Here, the fastening member 234 may be formed in a structure that functions as a bolt and connects with an insertion link member 233 that functions as a nut.

[0056] Referring to Figure 5, in another embodiment of the present invention, the medical lighting device 10 has the support portion 2312 of the light arm 210, the connection portion 2363 of the lamp unit holder 236, and the coupling portion 2321 of the fixed link member 232 positioned between the fastening member 234 and the insertion link member 233, and the light arm 210, lamp unit holder 236, and fixed link member 232 can be bound together by connecting the fastening member 234 and the insertion link member 233.

[0057] Here, the O-ring 235 is coupled to the insertion link member 233 and may be positioned between the coupling portion 2321 and the connecting portion 2363. The O-ring 235 may be made of rubber. This generates frictional force between the coupling portion 2321 and the connecting portion 2363, enabling a stepless angle adjustment function using frictional torque. In other words, instead of fixing the lamp module 220 at a fixed angle, the lamp module 220 can be fixed to stay at a desired angle.

[0058] Furthermore, by adjusting the fastening precision between the fastening member 234 and the insertion link member 233, the pressure applied to the O-ring 235 can be adjusted. This makes it possible to make the angle of the ramp module 220 adjustable or not.

[0059] The lamp unit holder 236 may include a connecting portion 2363 that extends from the main body and connects to a connecting portion 2321 of the fixed link member 232, and the connecting portion 2363 may include a connecting hole 2361 into which a fastening member 234 can be inserted.

[0060] The connecting portion 2363 may be positioned between the coupling portion 2321 and the support portion 2312. That is, when the fixed link member 232 is coupled to the lamp unit holder 236 and the light arm 210, the lamp unit holder 236 can accommodate the fixed link member 232, and the light arm 210 can accommodate and couple the lamp unit holder 236. In this case, the connecting portion 2363 is positioned coaxially with the coupling portion 2321, but it may also be positioned outside the coupling portion 2321.

[0061] Figure 6 illustrates the disassembly / assembly and power supply structure of the lamp module 220 and light arm 210 in a medical lighting device 10 according to another embodiment of the present invention.

[0062] Referring to Figure 6, the lamp unit holder 236 may further include contact terminals E1 and E2 that supply power to the lamp module 220. The contact terminals E1 and E2 can supply power to the LED light source 227 of the lamp module 220 by contacting contact terminals E3 and E4 of the light arm 210, respectively. On the other hand, in a plurality of lamp modules 220 coupled to the light arm 210, the terminal arrangement of the upper lamp module 220 and the lower lamp module 220 may differ. For example, the upper lamp module 220 may have contact terminals E1 and E2 located on the left or right side of the lamp unit holder 236, while the lower lamp module 220 may have contact terminals E1 and E2 located on the top or bottom of the lamp unit holder 236.

[0063] The lamp unit holder 236 is coupled with the fixed link member 232 to form a semi-finished lamp module 220, enabling the lamp module 220, including the fixed link member 232, to be fastened to the light arm 210. That is, the lamp unit holder 236 can function as a coupling medium between the light arm 210 and the lamp module 220. In one embodiment, when fastening the semi-finished lamp module 220 to the light arm 210, the light source unit 200 can primarily fix the lamp unit holder 236 to the light arm 210 with a rear screw 212, and secondarily fix the lamp module 220 to the light arm 210 with a fastening member 234 and a side screw 2341.

[0064] In one embodiment of the present invention, the medical lighting device 10 incorporates the angle adjustment unit 230 and the lamp unit into a single body, allowing the unit itself to be integrated into a single component, enabling quality checks at the component level, facilitating repairs and replacements, and simplifying post-maintenance without the need for wiring work or other procedures.

[0065] The following describes a medical lighting device 10 according to another embodiment of the present invention.

[0066] Figure 7 is a perspective view showing only the light source unit 200 in the medical lighting device 10 of Figure 1. Figure 8 is a perspective view showing the state before and after adjusting the angle of each lamp module 220 in the light source unit 200 of Figure 7, and Figure 9 is a side view showing the state before and after adjusting the angle of each lamp module 220 in the light source unit 200 of Figure 7. Figure 10 is an exploded perspective view of the light source unit 200 of Figure 7, and Figure 11 is an exploded perspective view of the angle adjustment unit 230 within the light source unit 200 of Figure 7.

[0067] Referring to Figures 7 to 11, in a medical lighting device 10 according to another embodiment of the present invention, the light source unit 200 includes a light arm 210, a lamp module 220, an angle adjustment unit 230, a handle 240, and a frame connection unit 211.

[0068] The angle adjustment section 230 may include a support member 231 positioned at one end of the light arm 210 in correspondence with the lamp module 220, a fixed link member 232 rotatably coupled to the support member 231, and an insertion link member 233 positioned between the fixed link member 232 and the support member 231. That is, the support member 231 may be formed at the upper and lower ends of the light arm 210 as a portion capable of accommodating multiple lamp modules 220.

[0069] Furthermore, the support member 231 may include a main body portion 2311 that houses a light source inside, and a pair of support portions 2312 that extend from the main body portion 2311 and connect to the fixed link member 232. That is, an empty space may be formed inside the main body portion 2311 to accommodate the combined body of the LED light source 227 and the heat sink 226 of the lamp module 220, and support portions 2312 may be formed extending from both sides of the main body portion 2311.

[0070] The support portion 2312 may have a first gear portion 2313 formed on one surface facing the insertion link member 233, and the insertion link member 233 may have a second gear portion 2331 formed on one surface corresponding to the support portion 2312 that meshes with the first gear portion 2313.

[0071] In other words, the ends of the support portions 2312, which extend from both sides of the main body portion 2311, may have first gear portions 2313 formed on their opposing inner surfaces. The first gear portion 2313 may have gears formed outward from the center of a circle having a certain diameter, such as a crown gear shape. Similarly, the second gear portion 2331 formed on the insertion link member 233 may also have a crown gear shape, similar to the first gear portion 2313. However, although the first gear portion 2313 and the second gear portion 2331 mesh with each other, if a force exceeding a certain amount is applied, slippage may occur, and the second gear portion 2331 may rotate out of alignment with the first gear portion 2313.

[0072] Furthermore, a coupling hole 2314 may be formed in the center of the first gear portion 2313. The protruding central part of the insertion link member 233 is formed to match the size of the coupling hole 2314 and can pass through the coupling hole 2314.

[0073] Referring to Figures 10 to 11, the angle adjustment unit 230 may further include a fastening member 234 connected to one of the pair of support units 2312, which fixes or releases the position of the fixed link member 232 to the support member 231.

[0074] The protruding central portion of the fastening member 234 is also formed to match the size of the coupling hole 2314, allowing the central portion of the fastening member 234, which penetrates the coupling hole 2314, to be connected and joined to the central portion of the insertion link member 233.

[0075] One of the fastening members 234 may have anti-slip grooves formed on its outer surface, while the other may have a smooth outer surface.

[0076] Referring again to Figures 7 to 11, the fixed link member 232 may include a housing portion 2322 that accommodates a part of the lamp module 220 and a pair of connecting portions 2321 positioned on both sides of the housing portion 2322 and connected to the support portion 2312 via the insertion link member 233. The pair of connecting portions 2321 may have a plurality of grooves 2324 formed therein for fixing and connecting the insertion link member 233.

[0077] In other words, there are connecting portions 2321 on both sides of the fixed link member 232 that connect to the insertion link member 233, and multiple grooves 2324 formed in these connecting portions 2321 engage with the protrusions 2332 of the insertion link member 233, thereby fastening the insertion link member 233 to the fixed link member 232. Between the pair of support portions 2312, the connected body of the insertion link member 233-fixed link member 232-insertion link member 233 is located, and the connecting holes 2314 of the support portion 2312 and the connecting portion 2321 of the fixed link member 232 are located on the same axis.

[0078] On the other hand, the housing portion 2322 of the fixed link member 232 plays the role of housing and fixing the components of the lamp module 220. That is, it can house and connect the LED light source 227 and the heat sink 226 assembly, and it can house and fix the lens portion 221. Specifically, a hollow may be formed in the center of the housing portion 2322, and one end portion 2211 of the lens portion 221 may be inserted into the hollow and assembled.

[0079] The fixed link member 232 may further include a pair of legs 2323 that extend from the pair of connecting portions 2321 and support a portion of the lamp module 220. The pair of legs 2323 can house and secure the lens portion 221, the light cover 224, and the like.

[0080] In a medical lighting device 10 according to another embodiment of the present invention, the lamp module 220 may be formed to be replaceable with respect to the fixed link member 232. That is, referring to Figure 10, the lamp module 220 may include a lens portion 221, a fixing ring 222, a cover glass 223, a light cover 224, and a light filter 225, but the configuration that connects to the housing portion 2322 and leg portion 2323 of the fixed link member 232 can be assembled and disassembled from the fixed link member 232.

[0081] In conventional medical lighting devices, the light source unit is integrally coupled with the part corresponding to the light arm and the lamp module, making disassembly and assembly impossible. However, in the medical lighting device 10 according to another embodiment of the present invention, only a part of the lamp module 220 can be disassembled and assembled, so the lens part 221 and other parts can be replaced.

[0082] On the other hand, according to another embodiment of the present invention, the angle of the lamp module 220 relative to the light arm 210 can be adjusted.

[0083] Referring again to Figures 8 and 9, we can see the state before and after narrowing the angle of each lamp module 220 relative to the light arm 210. The relative angle of each lamp module 220 relative to the light arm 210 can be adjusted via the angle adjustment unit 230.

[0084] In other words, the lamp module 220 forms a combined body with the fixed link member 232, and the fixed link member 232 is connected to the support part 2312 by the insertion link member 233, so the angle of the lamp module 220 can be adjusted up and down around the joint part 2321 as an axis.

[0085] On the other hand, although not shown, the angle adjustment section 230 may further include a guide section (not shown) that guides the angle of the lamp module 220 relative to the light arm 210 to be adjusted within a preset angle range. The angle adjustment section 230 may have a projection formed on the support section 2312 to prevent the lamp module 220 from rotating beyond a preset angle, or it may include a range adjustment guide section on the first gear section 2313 or the second gear section 2331.

[0086] In one embodiment, a guide unit (not shown) can perform a function that adjusts the angle of the other lamp module 220 when the user adjusts the angle of one lamp module 220. This provides the medical lighting device 10 with the convenience of being able to focus both lamp modules 220 at the desired position even if the user adjusts only the angle of one lamp module 220.

[0087] Alternatively, the guide unit (not shown) can perform a function in which, when the user adjusts the angle of one lamp module 220, the angle of the other lamp module 220 limits the available adjustment range depending on the adjusted angle.

[0088] Conventional medical headlamps have a problem in that the focal length at which the light emitted from each lamp module converges is constant, resulting in a constant distance between the headlamp and the treatment point, making them difficult to apply to various surgical environments. However, the medical lighting device 10 according to one embodiment of the present invention allows the focal length to be adjusted by adjusting the angle of each lamp module 220 of the light source unit 200, so that the distance to the treatment point can be adjusted to be closer or further according to the user's surgical environment.
