[0043] In the description of the embodiments of the present application, the "up", "down", and "length direction" orientation or positional relationship is based on the orientation or positional relationship shown in the attached drawings. Among them, the "top" in the attached drawings is consistent with the "up" in the attached drawings, and the "bottom" in the attached drawings is the same as the "bottom" in the attached drawings.

[0044] In the embodiments of the present application, the "first end" and the "second end" refer to orientations.

[0045] It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present application.

[0046] The embodiments of the present application provide an illumination system 3. Please refer to Figures 3 to 7 , which includes a mounting skeleton 35, a main control board 33, a directional lighting device, an ambient lighting device, and a housing 34.

[0047] The directional lighting device is arranged on the bottom side of the mounting skeleton 35. The directional lighting device includes at least one directional lighting array 31a. The directional lighting array 31a includes a plurality of lenses 312 and a plurality of first light sources 311. Each lens 312 is correspondingly provided with at least one first light source 311. In each directional lighting array 31a, please refer to Fig.16 , the light emitted by each first light source 311 is emitted toward the bottom side of the mounting skeleton 35 after being reflected by the correspondingly arranged lens 312 and converges in the convergence area, where the convergence area is within the area of a single hospital bed 5. The light spots of each first light source 311 emitted in the convergence area can at least partially overlap, can completely overlap (the shadowless effect is the best), or can be independent of each other without overlapping.

[0048] On the one hand, the illumination light of the directional lighting array 31a of the illumination system 3 is concentrated on a single hospital bed 5 and basically does not interfere with other areas around the hospital bed 5. In the case of multiple hospital beds 5 in the same ward, the influence on the patients 6 in adjacent hospital beds 5 can be reduced. On the other hand, every position in the convergence area can be irradiated by the light emitted by each lens 312. When medical staff perform examinations on patients 6, not all the lenses 312 can be completely blocked by the heads of the medical staff, and the light emitted by some lenses 312 will not be blocked. Therefore, the light projected by these lenses 312 can also be projected onto the convergence area. In this way, there is basically no umbra area in the convergence area on a single hospital bed 5. That is to say, the illumination of the directional lighting device can have a shadowless effect.

[0049] It should be noted that for the illumination system in the embodiments of the present application, the ambient lighting device and the directional lighting device can be independently controlled. For example, two chips are configured on the main control board 33, one of which is used to control the ambient lighting device and the other is used to control the directional lighting device.

[0050] Please refer to Figure 7 and Fig. 9 The atmosphere lighting device includes a plurality of second light sources 321, which are arranged on the top side of the mounting frame 35 to emit lighting light to the ceiling. The light emitted by the atmosphere lighting device is directed toward the ceiling, and after diffuse reflection from the ceiling, it is illuminated in the ward, and the light is soft, not glaring, and not dazzling.

[0051] The housing 34 is disposed around the mounting frame 35. Figure 2 and Figure 3 The housing 34 has a first light-transmitting surface 341 and a second light-transmitting surface 342. The first light-transmitting surface 341 is located at the bottom side of the lens 312 to transmit the light emitted through the lens 312, and the second light-transmitting surface 342 is used to transmit the light emitted by the second light source 321. The housing 34 constitutes the appearance surface of the lighting system 3, and can cover the structure arranged in the installation frame 35, so as to improve the appearance aesthetics of the lighting system 3.

[0052] The lighting system 3 of the embodiment of the present application can provide directional lighting to a single bed area through a directional lighting device, and can also achieve general lighting through an atmosphere lighting device. It has diversified functions and can meet the diverse needs of users.

[0053] In one embodiment, the distance between the two endpoints of the first light-transmitting surface 341 is greater than or equal to 40 cm, that is, in the first light-transmitting surface 341, the straight-line distance between at least two endpoints is greater than 40 cm. This size is much larger than the head size of an average adult. When medical staff examine the patient 6 on the bed 5 under the lighting system 3, the first light-transmitting surface 341 will not be completely blocked by the medical staff, and a part of the light passing through the first light-transmitting surface 341 can always illuminate the convergence area in the bed area.

[0054] For example, in one embodiment, please refer to Figure 2 The first light-transmitting surface 341 is roughly rectangular, the width of the first light-transmitting surface 341 along the horizontal direction of the mounting frame 35 is greater than or equal to 30 cm, and the length of the first light-transmitting surface 341 along the vertical direction of the mounting frame 35 is greater than or equal to 42 cm. In other words, the area of ​​the first light-transmitting surface 341 is greater than or equal to 1260 cm 2 It is understandable that the shape of the first light-transmitting surface 341 may also be other shapes, such as an ellipse, a pentagon, and the like.

[0055] It should be noted that the part of the housing 34 that does not need to be transparent is made of opaque material. The material of the first transparent surface 341 includes but is not limited to the following materials: polymethyl methacrylate (commonly known as organic glass), polystyrene, polycarbonate, styrene acrylonitrile, etc.

[0056] The lighting system 3 of the embodiment of the present application can be applied to any appropriate occasion and can be used as an independent product or combined with other products, for example, installed on a wall or integrated into mechanical equipment, etc., without limitation here.

[0057] In one embodiment, please refer to Figures 5 to 7 , the at least one directional lighting array 31a includes at least one first directional lighting array 31aʹ and at least one second directional lighting array 31a″. That is to say, in this embodiment, the number of directional lighting arrays 31a is multiple, among which a part of the directional lighting arrays 31a are the first directional lighting arrays 31aʹ, and another part of the directional lighting arrays 31a are the second directional lighting arrays 31a″. The convergence area of ​​the at least one first directional lighting array 31aʹ is the first convergence area 30a, that is, the convergence area of ​​all the first directional lighting arrays 31aʹ is the first convergence area 30a. The convergence area of ​​the at least one second directional lighting array 31a″ is the second convergence area 30b, that is, the convergence area of ​​all the second directional lighting arrays 31a″ is the second convergence area 30b.

[0058] The first convergence area 30a and the second convergence area 30b correspond to different parts of the body of the patient 6 lying in the single bed area. Figure 1 The first convergence area 30 a corresponds to the head area of ​​the patient 6 on the bed 5 , and the second convergence area 30 b corresponds to the torso area of ​​the patient 6 on the bed 5 .

[0059] In one embodiment, please refer to Figures 7 to 9 The mounting frame 35 includes a first frame plate 351 and a second frame plate 352 connected to each other. The first frame plate 351 has a first mounting surface 351a, and the first directional lighting array 31a' is mounted on the first mounting surface 351a of the first frame plate 351. The second frame plate 352 has a second mounting surface 352a, and the second directional lighting array 31a" is mounted on the second mounting surface 352a of the second frame plate 352. The normal of the first mounting surface 351a intersects with the normal of the second mounting surface 352a, and the intersection point is located in the space between the lighting system and the single bed area, that is, at least one of the first mounting surface 351a and the second mounting surface 352a is inclined toward the direction of the other. In this way, the first directional lighting array 31a' and the second directional lighting array 31a" can have different inclination angles, so that the first directional lighting array 31a' and the second directional lighting array 31a" have different convergence areas.

[0060] In one embodiment, the acute angle formed by the first mounting surface 351a and the horizontal plane is smaller than the acute angle formed by the second mounting surface 352a and the horizontal plane, so that the light emitted by the second directional lighting array 31a″ can be projected toward a farther area. For example, the light of the first directional lighting array 31aʹ converges toward the patient's head area, and the light of the second directional lighting array 31a″ converges toward the torso area of ​​the patient 6 that is farther away.

[0061] In some embodiments, the first mounting surface 351a is a whole plane, that is, a continuous plane, so as to facilitate the concentration step of the first light source 311 and the lens 312 in the first directional lighting array 31aʹ.

[0062] In some embodiments, the second mounting surface 352a includes a plurality of parallel sub-mounting surfaces, each of which extends in the longitudinal direction of the mounting frame, and the plurality of sub-mounting surfaces form a stepped structure. For example, one or two second directional lighting arrays 31a″ are mounted on each sub-mounting surface, so that the lens 312 on the second mounting surface 352a can have a larger mounting inclination angle, so that the light emitted from the lens 312 can converge to the torso area of ​​the patient 6 that is farther away.

[0063] In one embodiment, the number of lenses 312 in each directional lighting array 31a is multiple, for example, 8 lenses 312. Figure 5 The multiple lenses 312 in each directional lighting array 31a are arranged in a straight line along the longitudinal direction of the mounting frame 35.

[0064] In one embodiment, please refer to Fig.16 Each directional lighting array 31a further includes flanges 312b located on two pairs of lateral sides of the exit surface 3122 of the lens 312, the flanges 312b extending along the arrangement direction of the multiple lenses 312, and each lens 312 is located between the two flanges 312b. The flanges 312b can improve the structural strength of the directional lighting array 31a.

[0065] It should be noted that the installation position of the main control board 33 is not limited, and it can be installed on the installation frame 35 or installed at other positions.

[0066] In one embodiment of the present application, please refer to Figure 7The directional lighting device and the atmosphere lighting device are arranged at the first transverse end of the mounting frame 35, and the second transverse end of the mounting frame 35 has a receiving chamber 35a, and the main control board 33 is arranged in the receiving chamber 35a. In this way, the main control board 33 can be confined in the mounting frame 35, so as to prevent the main control board 33 from protruding from the outer surface of the mounting frame 35 and prevent other components from scratching the main control board 33. In addition, by arranging the main control board 33 at the second transverse end of the mounting frame 35, it is also possible to prevent the installation position of the main control board 33 from interfering with the installation positions of the directional lighting array 31a and the second light source 321.

[0067] It should be noted that the specific shape of the accommodation chamber 35 a is not limited as long as it can accommodate the main control board 33 .

[0068] In one embodiment, the mounting frame 35 is a metal part, that is, the mounting frame 35 is made of metal material. By utilizing the thermal conductivity of metal, the heat generated by the heating elements in the lighting system 3 can be dissipated in time, such as the heat generated by the main control board 33, light source, etc.

[0069] The specific type of metal material of the mounting frame 35 is not limited, as long as it can conduct heat, for example, it can be copper, iron, aluminum, etc.; it can be pure metal or alloy. The mounting frame 35 can be made of the same metal for the entire structure, or different metals can be used for different parts, which is not limited here.

[0070] In order to prevent the main control board 33 from directly contacting the metal mounting frame 35, in one embodiment, refer to Fig.10 The lighting system 3 includes an insulating bracket 37, on which the main control board 33 is fixedly mounted, and the insulating bracket 37 is fixedly connected to the mounting frame 35. That is, the main control board 33 and the mounting frame 35 are separated by the insulating bracket 37, so as to ensure electrical insulation between the main control board 33 and the mounting frame 35 and prevent conductive contact.

[0071] In one embodiment, please refer to Fig.10 and Fig.12 The side of the accommodation chamber 35a away from the first end is provided with an opening 35b, and a card slot 35c is provided in the accommodation chamber 35a. The end of the insulating bracket 37 can be placed in the accommodation chamber 35a through the opening 35b and carded into the card slot 35c. Please refer to Fig.13 , the other part of the insulating bracket 37 is located outside the accommodation chamber 35a. The end of the insulating bracket 37 away from the opening 35b is limited by the card slot 35c, so that the end of the insulating bracket 37 away from the opening 35b will not deflect, thereby increasing the stability of the insulating bracket 37.

[0072] During the assembly process, the main control board 33 can be first fixed on the insulating bracket 37, and then the insulating bracket 37 can be pushed from the opening 35b to the receiving chamber 35a until the end of the insulating bracket 37 is inserted into the card slot 35c, so that the insulating bracket 37 can be quickly positioned. It can be seen that there is a large operating space during the assembly process, which is convenient for assembly. In this embodiment, after the insulating bracket 37 is placed in the receiving chamber 35a, the insulating bracket 37 outside the receiving chamber 35a can be fastened to the mounting frame 35, for example, by screw connection, or the portion of the insulating bracket 37 inside the receiving chamber 35a can be fastened to the mounting frame 35.

[0073] The specific structure of the slot 35c is adapted to the shape of the end of the insulating bracket 37. Fig. 9 and Fig.10 The wall surface of the accommodation chamber 35a is provided with a convex rib 35d, and the extension direction of the convex rib 35d is the same as the extension direction of the end of the insulating bracket 37. The above-mentioned clamping groove 35c is formed between the convex rib 35d and the bottom surface of the accommodation chamber 35a. When the end of the insulating bracket 37 is inserted into the clamping groove 35c, the convex rib 35d stops and limits the insulating bracket 37 to prevent the end of the insulating bracket 37 from deflecting toward the convex rib 35d.

[0074] The specific structural form of the insulating bracket 37 is not limited. For example, in one embodiment, please refer to Fig.10 The insulating bracket 37 is generally L-shaped. Specifically, the insulating bracket 37 includes a first insulating plate 371 and a second insulating plate 372 connected to each other, wherein the first insulating plate 371 is located outside the accommodation chamber 35a and abuts against the mounting frame 35 around the opening 35b, the second insulating plate 372 is located inside the accommodation chamber 35a, the main control board 33 is arranged on the second insulating plate 372, and the second insulating plate 372 is supported on the bottom surface of the accommodation chamber 35a. The end of the second insulating plate 372 away from the first insulating plate 371 is inserted into the above-mentioned card slot 35c. In this embodiment, the matching mode of the insulating bracket 37 and the mounting frame 35 is similar to a drawer.

[0075] In one embodiment, please refer to Figure 4 The second insulating plate 372 covers the opening 35b, that is, the opening 35b is closed by the second insulating plate 372. The second insulating plate 372 can play a role in fixing the installation on the one hand, and can also play a role in covering the opening 35b on the other hand. In this embodiment, the second insulating plate 372 constitutes the appearance surface of the lighting system 3.

[0076] In one embodiment, in order to facilitate the installation of the lighting system 3 in other equipment or on a wall, please refer to Figure 4, a mounting structure 35e is provided on the mounting frame 35, and the lighting system 3 is mounted on other structures through the mounting structure 35e. That is, a connection structure for external connection is reserved on the lighting system 3. When the lighting system 3 does not need to be integrated with other equipment or walls, the lighting system 3 can be used alone. When the lighting system 3 needs to be integrated with other equipment or walls, it can be installed through the mounting structure 35e, which can increase the selectivity of using the lighting system 3.

[0077] The specific structure of the mounting structure 35e is not limited, for example, it can be a hook, a clip, etc. In one embodiment, the mounting structure 35e is a threaded hole. During installation, it is only necessary to pass the screws from the outside through the connected body and the threaded hole in sequence, and the installation method is simple and reliable.

[0078] In one embodiment, please refer to Figure 8 and Fig. 9 The mounting frame 35 includes a frame 353, one end of the frame 353 is connected to the first frame plate 351, the second frame plate 352 is connected between the first frame plate 351 and the frame 353, the other end of the frame 353 is formed with the above-mentioned opening 35b, and the space inside the frame 353 is the accommodation chamber 35a. Specifically, the frame 353 includes a top plate 3531, a bottom plate 3532, and two connecting plates 3533 connected between the top plate 3531 and the bottom plate 3532, the two connecting plates 3533 are located at opposite sides of the opening 35b, and the top plate 3531, the bottom plate 3532 and the two connecting plates 3533 are jointly arranged to form the above-mentioned opening 35b.

[0079] In one embodiment, please refer to Fig. 9 and Fig.11 The mounting frame 35 is open at two opposite ends along the extending direction of the slot 35c. During the assembly process, the operator can assemble from the open parts of the mounting frame 35. Figure 4 In some embodiments, after the assembly is completed, the housing 34 is used to seal the opening of the mounting frame 35. In this way, the main control board 33 and other electrical components can be completely encapsulated inside the lighting system 3, so that there are no exposed electrical components outside the lighting system 3, thereby improving the safety of the lighting system 3. Fig.11 In other embodiments, the opening of the mounting frame 35 does not need to be closed. During installation, the mounting frame 35 can be embedded in other structures for shielding.

[0080] In some embodiments, at least a portion of the multiple first light sources 311 of the directional lighting array 31a are arranged in parallel in the circuit, that is, all of the first light sources 311 are not connected in series, and the connection circuit of the first light sources 311 is divided into multiple parallel branches. In this way, when the first light source 311 on one of the parallel branches is damaged, the first light sources 311 on other parallel branches can be used normally, and the entire directional lighting array will not be scrapped.

[0081] The parallel connection mode of the plurality of first light sources 311 in the circuit is not limited. Fig.12 , Fig.12 In the circuit connection diagram of some first light sources 311 of the first embodiment of the present application, the first light sources 311 of the directional lighting array adopt a matrix connection method. All the first light sources 311 in the same directional lighting array 31a are connected in parallel, and multiple directional lighting arrays 31a are connected in series. Specifically, take the first light source 311 as an LED lamp (Light Emitting Diode), there are 3 directional lighting arrays 31a, and each directional lighting array 31a has 8 LED lamps as an example. When a certain LED lamp in one of the directional lighting arrays 31a is damaged, the current can still flow through the remaining 7 branches, that is, the LED lamps on the remaining 7 branches can still be used normally. It should be noted that in other embodiments, the number of LED lamps in each directional lighting array 31a can be equal or unequal. The LED lamps in each directional lighting array 31a can be partially connected in series and partially connected in parallel.

[0082] See also Fig.13 , Fig.13 This is a circuit connection diagram of multiple first light sources 311 of the second embodiment of the present application. This embodiment still takes the first light source 311 as an LED lamp (Light Emitting Diode), with 3 directional lighting arrays 31a, each directional lighting array 31a has 8 LED lamps as an example, and the 8 LED lamps in each directional lighting array 31a are arranged in 8 parallel branches, wherein the branches in two directional lighting arrays 31a correspond to each other and are arranged in series, so that the two directional lighting arrays 31a together form 8 parallel branches and then are connected in series with another directional lighting array 31a, and each parallel branch is provided with 2 LED lamps.

[0083] See also Fig.14 , Fig.14This is a circuit connection diagram of multiple first light sources 311 of the second embodiment of the present application. This embodiment still takes the first light source 311 as an LED lamp (Light Emitting Diode), with 3 directional lighting arrays 31a, each directional lighting array 31a has 8 LED lamps as an example, each directional lighting array 31a has 8 branches, and the branches in the three directional lighting arrays 31a correspond to each other and are arranged in series, so that the three directional lighting arrays 31a together form 8 parallel branches, and each parallel branch is provided with 3 LED lamps.

[0084] See also Fig.15 , Fig.15 This is a schematic diagram of the circuit connection of a plurality of first light sources 311 according to the third embodiment of the present application. In this embodiment, the circuits of the LED lights of the three directional lighting arrays are mixed.

[0085] It is understandable that the circuit connection method of the multiple first light sources 311 is not limited. In addition to the above embodiments, there may be other embodiments, such as arranging all the first light sources 311 in parallel, that is, only one first light source 311 is arranged on each parallel branch.

[0086] Similarly, at least a portion of the multiple second light sources 321 are arranged in parallel in the circuit, that is, the circuit of the atmosphere lighting device will be divided into multiple parallel branches. In this way, when the second light source 321 on one of the parallel branches is damaged, the second light sources 321 on other parallel branches can be used normally, and the entire atmosphere lighting device will not be scrapped.

[0087] It should be noted that the second light source 321 can adopt the circuit connection methods of the various embodiments of the first light source 311 described above. Of course, the second light source 321 can also adopt other circuit connection methods, which will not be described in detail here.

[0088] In one embodiment, some of the second light sources 321 among all the second light sources 321 are cold white light sources, and another part of the second light sources 321 are warm white light sources. During the operation of the ambient lighting device, the ratio of the number of cold white light sources turned on to the number of warm white light sources turned on is different in at least two time periods, and / or the current ratio of the cold white light sources and the warm white light sources is different in at least two time periods.

[0089] The color temperature of the overall light of the atmosphere lighting device is the mixed color temperature of all turned-on second light sources 321. In one embodiment, the color temperature is adjusted by changing the ratio of the number of turned-on second light sources 321 of different color temperatures. For example, the number of turned-on cold white light sources is 12, and the number of turned-on warm white light sources is 12. At this time, the ratio of the number of turned-on second light sources 321 of the two color temperatures is 1:1, which corresponds to one color temperature of the atmosphere lighting device. When the color temperature needs to be adjusted, the number of cold white light sources and warm white light sources is adjusted. For example, the number of turned-on cold white light sources is 10, and the number of turned-on warm white light sources is 12. At this time, the ratio of the number of turned-on second light sources 321 of the two color temperatures is 5:6, which corresponds to another color temperature of the atmosphere lighting device, that is, the color temperature of the atmosphere lighting device has changed.

[0090] In another embodiment, the purpose of adjusting the color temperature of the directional lighting device can be achieved by adjusting the light color ratio of the second light source 321 with different color temperatures. Specifically, the light color ratio of the second light source 321 with different color temperatures is adjusted by changing the current of the second light source 321 corresponding to different color temperatures. For example, the current of the cold white light source is 2mA, and the current of the warm white light source is 3mA. This current ratio corresponds to a color temperature of the directional lighting device. When the color temperature needs to be changed, for example, the current of the cold white light source is adjusted to 3mA, and the current of the warm white light source is adjusted to 4mA. At this time, the light color ratio of the second light source 321 with different color temperatures has changed, that is, the color temperature of the directional lighting device has changed.

[0091] Exemplarily, the illumination of the directional lighting device is adjusted by proportionally changing the current corresponding to the first light source 311 of different color temperatures. For example, the current of the cold white light source is 2mA, and the current of the warm white light source is 3mA. At this time, the current ratio of the cold white light source and the warm white light source is 2:3, which corresponds to a color temperature and an illumination of the directional lighting device. When only the illumination needs to be changed without adjusting the color temperature, the current of the cold white light source and the warm white light source is increased or decreased proportionally. For example, the cold white light source is adjusted to 4mA, and the current of the warm white light source is 6mA. At this time, the illumination can be adjusted while keeping the color temperature unchanged. It should be noted that when the current of the first light source 311 of different color temperatures changes non-proportionally, the color temperature and illumination of the directional lighting device will change.

[0092] It is understandable that during the operation of the ambient lighting device, the ratio of the number of cold white light sources turned on to the number of warm white light sources turned on can be changed in a certain time period, and the current ratio of the cold white light sources and the warm white light sources can be changed in another time period.

[0093] It will be appreciated that illumination and color temperature may be adjusted individually or simultaneously.

[0094] In some hospitals, ICU and other wards have no or few windows facing the natural outside world, and natural light cannot reach the location of patient 6, so the entire ward uses artificial lighting. In wards with artificial lighting, lighting fixtures are turned on for a long time, and the lighting environment in the entire room is constant, without lighting rhythm changes, which in turn affects the rhythm regulation function of patient 6, affects the secretion of melatonin by patient 6, affects the sleep of patient 6 and medical staff, and may be detrimental to the recovery and physical and mental health of patient 6, as well as the work and physical and mental health of medical staff.

[0095] To this end, in the embodiment of the present application, the lighting mode of the atmosphere lighting unit includes a rhythmic mode, in which the color temperature and illuminance of the light emitted by the atmosphere lighting unit change according to a preset rule, so that the lighting in the ward presents a rhythmic change. The above-mentioned preset rule can be to determine the corresponding illuminance only according to time, or to comprehensively determine the color temperature and brightness of the light emitted by the atmosphere lighting unit according to time and the current natural light illuminance in the ward.

[0096] In the present application, please refer to Fig.17 , the preset rule is a simulated circadian rhythm rule, that is, the corresponding illumination is determined only according to the time. The simulated circadian rhythm rule refers to simulating the natural lighting conditions in nature for 24 hours a day, which includes color temperature and illumination information, and forming a database of the corresponding relationship between time and lighting conditions. Specifically, when the user turns on the rhythm mode, the lighting system obtains the corresponding preset illumination information and color temperature information in the database according to the current time, and then controls the color temperature and brightness of the atmosphere lighting unit.

[0097] It should be noted that the directional lighting array 31a may also have a rhythmic pattern, and its rhythmic control rule may be the same as the rhythmic control rule of the atmosphere lighting unit, or may be different, and there is no limitation here.

[0098] In one embodiment, the lighting mode of the directional lighting device includes at least one of a reading mode, an inspection mode, and a light stimulation mode.

[0099] In the embodiment where the lighting mode of the directional lighting device includes a reading mode, the illumination of the directional lighting array 31a is in the range of 300 lx-2000 lx, the color temperature is in the range of 3000K~5000K, and the color temperature is kept constant. For example, when the patient 6 needs to read on the bed 5, high illumination is not required, and the above color temperature range and illumination range can better meet the lighting needs of the patient 6 when reading. It should be noted that in the reading mode, the color temperature of the directional lighting array 31a is unchanged, and the illumination is not limited. That is to say, in some embodiments, the color temperature cannot be adjusted, but the illumination can be adjusted. In another embodiment, neither the illumination nor the color temperature can be adjusted.

[0100] In an embodiment where the lighting mode of the directional lighting device includes an inspection mode, the illumination of the directional lighting array 31a is in the range of 1000lx-10000lx, the color temperature is in the range of 3000K~5000K, and the color temperature is kept constant. For example, when medical staff need to examine patient 6, the above-mentioned range of color temperature and illumination is required in the torso area of ​​patient 6, and the medical staff can perform clinical operations such as intubation under this illumination. It should be noted that in the inspection mode, the color temperature of the directional lighting array 31a remains unchanged and the illumination is not limited. That is to say, in some embodiments, the color temperature cannot be adjusted, but the illumination can be adjusted. In another embodiment, neither the illumination nor the color temperature can be adjusted.

[0101] In an embodiment where the lighting mode of the directional lighting device includes a light stimulation mode, the illuminance of the directional lighting array 31a changes gradually, the maximum value of the illuminance is in the range of 2000 lx-10000 lx, and the color temperature of the directional lighting array 31a is kept unchanged. It is understandable that in the light stimulation mode, the light of the directional lighting array 31a can at least be projected onto the patient's head area so that the patient's eyes can feel the light. It should be noted that in the light stimulation mode, the color temperature of the directional lighting array 31a remains unchanged and the illuminance is not limited. That is to say, in some embodiments, the color temperature cannot be adjusted, but the illuminance can be adjusted. In another embodiment, neither the illuminance nor the color temperature can be adjusted.

[0102] For example, when it is necessary to promote the patient 6 to wake up from sleep, a time-controllable, high-illuminance regional illumination is provided to the head area of ​​the patient 6 through part of the first light source 311, and the patient 6 can feel the high-illuminance illumination in the eyes and wake up from the sleep state. Exemplarily, in one embodiment, in the light stimulation mode, the illumination of the head area of ​​the patient 66 gradually changes within a preset time length, for example, the sum of the preset light stimulation time periods is 10 minutes to 20 minutes, gradually increasing from no light to about 2000 lx to 10000 lx, and then gradually extinguishing.

[0103] In one embodiment, please refer to Fig.19 The lighting system includes a control terminal 4. The control terminal 4 includes a display controller 41 and a display panel 42. The display panel 42 is provided with a lighting mode switch key and / or an illumination adjustment key.

The wireless manner refers to that the control terminal transmits the control signal to the main control board through wireless transmission technology.

[0104] The specific type of the lighting mode switch key and / or the illumination adjustment key is not limited, for example, it can be a physical key, a touch key, a virtual button set on the display screen, etc., and is not limited here.

It should be noted that the display panel 382 is provided with a master switch key 3824, which is used to control the lighting system to be turned on or off.

[0106] When the user triggers any one of the lighting mode switch keys, the lighting system 3 can enter the lighting mode matching the lighting mode switch key.

[0107] In the embodiment where the lighting system 3 includes the above-mentioned inspection mode, reading mode and rhythm mode, please continue to refer to Fig.19 The illumination adjustment keys include an inspection mode illumination adjustment key 3826, a reading mode illumination adjustment key 3827, and a rhythm mode illumination adjustment key 3825.

[0108] In one embodiment, please refer to Fig.18 The control terminal 38 also includes a rear shell 384 and a front shell 383. The display panel 382 is arranged on the front side of the front shell 383. For example, the display panel 382 can be adhered to the front side of the front shell 383 by double-sided tape; the display controller 381 is arranged on the rear side of the front shell 383. For example, the display controller 381 can be adhered to the rear side of the front shell 383 by double-sided tape. The display panel 382, ​​the front shell 383 and the rear shell 384 together form a closed space, and the display controller 381 is arranged in the closed space between the front shell 383 and the rear shell 384. In this way, the live components can be enclosed in the closed space. Even if the control terminal 38 is not attached to other mechanical equipment, the control terminal 38 can also be used as a safe module for users to operate directly without the risk of electric shock.

[0109] In one embodiment, please continue to refer to Fig.18 The control terminal 38 further includes a key fixing frame 385, which is fixedly connected to the front shell 383 or the rear shell 384, and the control terminal 38 is connected to the mechanical device through the key fixing frame 385. For example, a connection hole can be set on the key fixing frame 385, and a detachable connection can be achieved through a connecting piece such as a screw or a bolt.

[0110] It can be understood that in order to make the installation of the control terminal 38 more secure, the key fixing frame 385 surrounds the circumference of the front shell 383 or the rear shell 384, and there are multiple connecting holes. The multiple connecting holes are arranged at intervals along the edge of the key fixing frame 385, so that the key fixing frame 385 is relatively evenly stressed along the circumference around the front shell 383 or the rear shell 384, thereby improving the installation reliability of the control terminal 38.
