[0054] It should be noted that, without conflict, the embodiments in the present application and the technical features in the embodiments can be combined with each other. The detailed description in the specific implementation manners should be understood as an explanatory illustration of the purpose of the present application and should not be regarded as an improper limitation to the present application.

[0055] In the description of the embodiments of the present application, the "top" and "bottom" orientation or positional relationship is based on the orientation or positional relationship shown in the attached Figure 9 drawing. The upper part in the attached Figure 9 drawing is "top", and the lower part is "bottom".

[0056] In the description of the embodiments of the present application, the "top", "bottom", and "length direction" orientation or positional relationship is based on the orientation or positional relationship shown in the attached Figure 13 drawing. Among them, the "top" in the attached Figure 9 drawing has the same orientation as the "top" in the attached Figure 13 drawing, and the "bottom" in the attached Figure 9 drawing has the same orientation as the "bottom" in the attached Figure 13 drawing.

[0057] In the embodiments of the present application, the "first end" and "second end" refer to orientations.

[0058] 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 should not be construed as a limitation to the present application.

[0059] The embodiments of the present application provide a lighting system 3. Please refer to Figures 3 to 7 , which includes an installation skeleton 35, a main control board 33, a directional lighting device, an ambient lighting device, and a housing 34.

[0060] The directional lighting device is arranged on the bottom side of the mounting frame 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. At least one first light source 311 is correspondingly arranged for each lens 312. In each directional lighting array 31a, please refer to Figure 16 , the light emitted by each first light source 311 is reflected by the correspondingly arranged lens 312 and then exits towards the bottom side of the mounting frame 35 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 exiting 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.

[0061] On the one hand, the lighting light of the directional lighting array 31a of the lighting 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 are examining patients 6, not all the lenses 312 can be completely blocked by the heads of the medical staff. The light emitted by some lenses 312 will not be blocked. Therefore, the light projected by these lenses 312 can also be projected towards the convergence area. Thus, there is basically no umbra area in the convergence area on a single hospital bed 5. That is to say, the lighting of the directional lighting device can have a shadowless effect.

[0062] It should be noted that for the lighting system in the embodiment of the present application, the atmosphere 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 atmosphere lighting device and the other is used to control the directional lighting device.

[0063] Please refer to Figure 7 and Figure 9 , the atmosphere lighting device includes a plurality of second light sources 321. The plurality of second light sources 321 are arranged on the top side of the mounting frame 35 to emit lighting light towards the ceiling. The light emitted by the atmosphere lighting device shines on the ceiling and is diffusely reflected by the ceiling and then irradiates in the ward. The light is soft, non-glare, and non-dazzling.

[0064] The housing 34 is arranged around the mounting frame 35. Please refer to 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 emit the light exiting through the lens 312, and the second light-transmitting surface 342 is used to emit the light emitted by the second light source 321. The housing 34 constitutes the outer surface of the lighting system 3, which can cover the structures arranged in the mounting frame 35 and enhance the aesthetic appearance of the lighting system 3.

[0065] The lighting system 3 according to the embodiment of the present application can provide directional lighting to a single hospital bed area through the directional lighting device, and can also achieve general lighting through the ambient lighting device. The functions are diversified, and it can meet the diverse needs of users.

[0066] In one embodiment, the distance between the two end points of the first light-transmitting surface 341 is greater than or equal to 40 cm. That is to say, in the first light-transmitting surface 341, the straight-line distance between at least two end points is greater than 40 cm. This size is much larger than the head size of an average adult. When medical staff perform examinations on the patient 6 on the hospital bed 5 below 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 exiting from the first light-transmitting surface 341 can always irradiate the convergence area within the hospital bed area.

[0067] Exemplarily, in one embodiment, please refer to Figure 2 , the first light-transmitting surface 341 is generally rectangular. The width of the first light-transmitting surface 341 along the transverse 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 longitudinal direction of the mounting frame 35 is greater than or equal to 42 cm. That is to say, the area of the first light-transmitting surface 341 is greater than or equal to 1260 cm 2 . It can be understood that the shape of the first light-transmitting surface 341 can also be other shapes, such as oval, pentagon, etc.

[0068] It should be noted that the parts of the housing 34 that do not need to be light-transmitting are made of light-impermeable materials. The materials of the first light-transmitting surface 341 include but are not limited to the following materials: polymethyl methacrylate (commonly known as plexiglass), polystyrene, polycarbonate, styrene acrylonitrile, etc.

[0069] The lighting system 3 according to the embodiment of the present application can be applied to any suitable occasion, can be used as an independent product, or can be combined with other products, for example, installed on the wall, or integrated in a mechanical device, etc., which is not limited herein.

[0070] In one embodiment, please refer to Figures 5 to 7, the at least one directional illumination array 31a includes at least one first directional illumination array 31a' and at least one second directional illumination array 31a". That is to say, in this embodiment, the number of directional illumination arrays 31a is multiple, and a part of the directional illumination arrays 31a is the first directional illumination array 31a', and another part of the directional illumination arrays 31a is the second directional illumination array 31a". The convergence area of the at least one first directional illumination array 31a' is the first convergence area 30a, that is to say, the convergence area of all the first directional illumination arrays 31a' is the first convergence area 30a. The convergence area of the at least one second directional illumination array 31a" is the second convergence area 30b, that is to say, the convergence area of all the second directional illumination arrays 31a" is the second convergence area 30b.

[0071] Wherein the first convergence area 30a and the second convergence area 30b respectively correspond to different parts of the patient 6's body lying within a single hospital bed area. For example, please refer to Figure 1 , the first convergence area 30a corresponds to the head area of the patient 6 on the hospital bed 5, and the second convergence area 30b corresponds to the torso area of the patient 6 on the hospital bed 5.

[0072] In one embodiment, please refer to Figures 7 to 9 , the mounting skeleton 35 includes a first skeleton plate 351 and a second skeleton plate 352 that are interconnected. The first skeleton plate 351 has a first mounting surface 351a, and the first directional illumination array 31a' is mounted on the first mounting surface 351a of the first skeleton plate 351. The second skeleton plate 352 has a second mounting surface 352a, and the second directional illumination array 31a" is mounted on the second mounting surface 352a of the second skeleton plate 352. The normal line of the first mounting surface 351a intersects the normal line of the second mounting surface 352a, and the intersection point is located in the space between the illumination system and the single hospital bed area. That is to say, at least one of the first mounting surface 351a and the second mounting surface 352a is inclined towards the direction where the other is located. In this way, it can be ensured that the first directional illumination array 31a' and the second directional illumination array 31a" have different inclination angles, so that the first directional illumination array 31a' and the second directional illumination array 31a" have different convergence areas.

[0073] 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. In this way, it can be ensured that the light emitted by the second directional illumination array 31a" can be projected towards a farther area. For example, the light of the first directional illumination array 31a' converges towards the head area of the patient, and the light of the second directional illumination array 31a" converges towards the torso area of the patient 6 farther away.

[0074] In some embodiments, the first mounting surface 351a is a continuous flat surface, i.e., a single, unbroken plane. This facilitates the concentration of the first light sources 311 and lenses 312 in the first directional illumination array 31a′. In some embodiments, the second mounting surface 352a includes a plurality of parallel sub-mounting surfaces, each extending longitudinally along the mounting frame. The plurality of sub-mounting surfaces form a stepped structure. For example, one or two second directional illumination arrays 31a″ are mounted on each sub-mounting surface. This enables the lenses 312 on the second mounting surface 352a to have a larger mounting tilt angle, causing the light rays emitted from the lenses 312 to converge towards the torso area of the patient 6 further away.

[0075] In one embodiment, the number of lenses 312 in each directional illumination array 31a is multiple, e.g., eight lenses 312. Refer to Figure 5 , and the multiple lenses 312 in each directional illumination array 31a are arranged in a straight line along the longitudinal direction of the mounting frame 35.

[0076] In one embodiment, refer to Figure 16 , each directional illumination array 31a further includes flanges 312b on both sides of the two lateral pairs of the exit surface 3122 of the lens 312. The flanges 312b extend along the arrangement direction of the multiple lenses 312, and each lens 312 is located between the two flanges 312b. The flanges 312b can enhance the structural strength of the directional illumination array 31a.

[0077] It should be noted that the mounting position of the main control board 33 is not limited. It can be mounted on the mounting frame 35 or at other positions.

[0078] In one embodiment of the present application, refer to Figure 7 , the directional illumination device and the ambient illumination device are arranged at the first lateral end of the mounting frame 35. The second lateral end of the mounting frame 35 has a receiving chamber 35a, and the main control board 33 is arranged in the receiving chamber 35a. This can confine the main control board 33 within the mounting frame 35, preventing the main control board 33 from protruding from the outer surface of the mounting frame 35 and avoiding other components from rubbing against the main control board 33. In addition, arranging the main control board 33 at the second lateral end of the mounting frame 35 can also prevent the mounting position of the main control board 33 from interfering with the mounting positions of the directional illumination array 31a and the second light source 321.

[0079] It should be noted that the specific shape of the receiving chamber 35a is not limited, as long as it can accommodate the main control board 33.

[0080] In one embodiment, the mounting frame 35 is a metal part, i.e., the material of the mounting frame 35 is a metal material. Utilizing the heat conductivity of the metal, the heat generated by the heating elements in the lighting system 3 can be dissipated in a timely manner, such as the heat generated by the main control board 33, light sources, etc.

[0081] The specific type of the metal material for installing the skeleton 35 is not limited as long as it can conduct heat. For example, it can be copper, iron, aluminum, etc.; it can be a pure metal or an alloy. The installation skeleton 35 can be made of the same metal for the whole structure or different metals for different parts, which is not limited here.

[0082] In order to prevent the main control board 33 from directly contacting the installation skeleton 35 made of metal, in one embodiment, please refer to Figure 10 , the lighting system 3 includes an insulating bracket 37. The main control board 33 is fixedly arranged on the insulating bracket 37, and the insulating bracket 37 is fixedly connected to the installation skeleton 35. That is to say, the main control board 33 and the installation skeleton 35 are separated by the insulating bracket 37 to ensure electrical insulation between the main control board 33 and the installation skeleton 35 and prevent conductive contact.

[0083] In one embodiment, please refer to Figure 10 and Figure 12 , an opening 35b is arranged on one side of the accommodation chamber 35a away from the first end, a clamping groove 35c is arranged in the accommodation chamber 35a, and the end of the insulating bracket 37 can be inserted into the accommodation chamber 35a from the opening 35b and snapped into the clamping groove 35c. Please refer to Figure 13 , another part of the insulating bracket 37 is located outside the accommodation chamber 35a. The clamping groove 35c limits the end of the insulating bracket 37 away from the opening 35b, so that the end of the insulating bracket 37 away from the opening 35b will not deflect, increasing the stability of the insulating bracket 37.

[0084] During the assembly process, the main control board 33 can be first fixed on the insulating bracket 37, and then the insulating bracket 37 is pushed from the opening 35b towards the accommodation chamber 35a until the end of the insulating bracket 37 is snapped into the clamping groove 35c, so that the rapid positioning of the insulating bracket 37 can be realized. 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 inserted into the accommodation chamber 35a, either the insulating bracket 37 outside the accommodation chamber 35a and the installation skeleton 35 can be firmly connected, for example, by screw connection, or a part of the insulating bracket 37 inside the accommodation chamber 35a and the installation skeleton 35 can be firmly connected.

[0085] The specific structural form of the clamping groove 35c is adapted to the shape of the end of the insulating bracket 37. In one embodiment, please refer to Figure 9 and Figure 10, the wall surface of the accommodation chamber 35a is provided with a rib 35d, the extending direction of the rib 35d is the same as that of the end of the insulating bracket 37, and the above-mentioned card slot 35c is formed between the rib 35d and the bottom surface of the accommodation chamber 35a. After the end of the insulating bracket 37 is inserted into the card slot 35c, the rib 35d stops and positions the insulating bracket 37 to prevent the end of the insulating bracket 37 from deflecting towards the direction of the rib 35d.

[0086] The specific structural form of the insulating bracket 37 is not limited. Exemplarily, in one embodiment, please refer to Figure 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 that are connected to each other. Among them, the first insulating plate 371 is located outside the accommodation chamber 35a and abuts against the mounting skeleton 35 around the opening 35b, and 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 snapped into the above-mentioned card slot 35c. In this embodiment, the cooperation mode between the insulating bracket 37 and the mounting skeleton 35 is similar to that of a drawer.

[0087] In one embodiment, please refer to Figure 4 , the second insulating plate 372 covers the opening 35b. That is to say, the opening 35b is closed by the second insulating plate 372. On the one hand, the second insulating plate 372 can play a role in fixing and installing, and on the other hand, it can also play a role in covering the opening 35b. In this embodiment, the second insulating plate 372 constitutes the appearance surface of the lighting system 3.

[0088] In one embodiment, in order to facilitate the installation of the lighting system 3 on other devices or walls and the like, please refer to Figure 4 , the mounting skeleton 35 is provided with a mounting structure 35e, and the lighting system 3 is installed on other structures through the mounting structure 35e. That is to say, a connection structure for external connection is reserved on the lighting system 3. When the lighting system 3 does not need to be integrated and used on other devices or walls and the like, the lighting system 3 can be used alone. When it is necessary to integrate the lighting system 3 and use it on other devices or walls and the like, it can be installed through the mounting structure 35e, so that the selectivity of using the lighting system 3 can be increased.

[0089] The specific structure of the mounting structure 35e is not limited. For example, it can be structures such as hooks and clips. In one embodiment, the mounting structure 35e is a threaded hole. During installation, only need to pass the screw through the connected body and the above-mentioned threaded hole in sequence from the outside, and the installation method is simple and reliable.

[0090] In one embodiment, please refer to Figure 8 and Figure 9, the mounting skeleton 35 includes a frame body 353. One end of the frame body 353 is connected to the first skeleton plate 351, and the second skeleton plate 352 is connected between the first skeleton plate 351 and the frame body 353. The other end of the frame body 353 is formed with the above-mentioned opening 35b, and the space inside the frame body 353 is an accommodation chamber 35a. Specifically, the frame body 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 on opposite sides of the opening 35b, and the top plate 3531, the bottom plate 3532, and the two connecting plates 3533 together enclose the above-mentioned opening 35b.

[0091] In one embodiment, please refer to Figure 9 and Figure 11 , the opposite ends of the mounting skeleton 35 along the extending direction of the card slot 35c are open. During the assembly process, the operator can perform the assembly from the open part of the mounting skeleton 35. Please refer to Figure 4 , in some embodiments, after the assembly is completed, the housing 34 is used to close the open part of the mounting skeleton 35. In this way, electrical components such as the main control board 33 can be completely encapsulated inside the lighting system 3, so that there are no exposed electrical components outside the lighting system 3, improving the safety of the lighting system 3. Please refer to Figure 11 , in other embodiments, the open part of the mounting skeleton 35 does not need to be closed. During installation, the mounting skeleton 35 can be embedded in other structures for shielding.

[0092] In some embodiments, at least a part of the multiple first light sources 311 of the directional lighting array 31a are connected in parallel in the circuit. That is to say, not all of the first light sources 311 adopt a series connection method. 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 still be used normally, and the entire directional lighting array will not be scrapped.

[0093] The parallel connection method of the multiple first light sources 311 in the circuit is not limited. For example, please refer to Figure 12 , Figure 12In the circuit connection schematic diagram of part of the first light source 311 in the first embodiment of the present application, the first light sources 311 of the directional illumination array adopt a matrix connection method. All the first light sources 311 within the same directional illumination array 31a are connected in parallel, and multiple directional illumination arrays 31a are connected in series. Specifically, taking the first light source 311 as an LED lamp (Light Emitting Diode), there are 3 directional illumination arrays 31a, and each directional illumination array 31a has 8 LED lamps as an example. When a certain LED lamp within one of the directional illumination arrays 31a is damaged, the current can still flow through the remaining 7 branches. That is to say, 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 within each directional illumination array 31a can be equal or unequal. The LED lamps within each directional illumination array 31a can be partially connected in series and partially connected in parallel.

[0094] Please refer to Figure 13 , Figure 13 In the circuit connection schematic diagram of multiple first light sources 311 in the second embodiment of the present application. In this embodiment, still taking the first light source 311 as an LED lamp (Light Emitting Diode), there are 3 directional illumination arrays 31a, and each directional illumination array 31a has 8 LED lamps as an example. The 8 LED lamps within each directional illumination array 31a are arranged on 8 parallel branches. The branches in two of the directional illumination arrays 31a are in one-to-one correspondence and connected in series, so that the 2 directional illumination arrays 31a together form 8 parallel branches and then are connected in series with another directional illumination array 31a, and 2 LED lamps are arranged on each parallel branch.

[0095] Please refer to Figure 14 , Figure 14 In the circuit connection schematic diagram of multiple first light sources 311 in the second embodiment of the present application. In this embodiment, still taking the first light source 311 as an LED lamp (Light Emitting Diode), there are 3 directional illumination arrays 31a, and each directional illumination array 31a has 8 LED lamps as an example. There are 8 branches in each directional illumination array 31a. The branches in the 3 directional illumination arrays 31a are in one-to-one correspondence and connected in series, so that the 3 directional illumination arrays 31a together form 8 parallel branches, and 3 LED lamps are arranged on each parallel branch.

[0096] Please refer to Figure 15 , Figure 15 In the circuit connection schematic diagram of multiple first light sources 311 in the third embodiment of the present application. In this embodiment, the circuits of the LED lamps in the 3 directional illumination arrays are mixedly arranged.

[0097] It can be understood that the circuit connection manner of the multiple first light sources 311 is not limited. In addition to the above embodiments, there may be other embodiments. For example, all the first light sources 311 are connected in parallel, that is, only one first light source 311 is provided on each parallel branch.

[0098] Similarly, at least a part of the multiple second light sources 321 is connected in parallel in the circuit. That is to say, the circuit of the atmosphere lighting device is divided into multiple parallel branches. In this way, when a second light source 321 on one parallel branch is damaged, the second light sources 321 on other parallel branches can still be used normally, and the entire atmosphere lighting device will not be scrapped.

[0099] It should be noted that the second light source 321 can adopt the circuit connection manners 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 manners, which will not be elaborated here.

[0100] In one embodiment, some of all the second light sources 321 are cold white light sources, and the other part of the second light sources 321 are warm white light sources. During the operation of the atmosphere lighting device, the ratio of the number of turned-on cold white light sources to the number of turned-on warm white light sources 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.

[0101] The color temperature of the overall light of the atmosphere lighting device is the mixed color temperature of all the 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 with 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, corresponding to a certain 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, corresponding to another color temperature of the atmosphere lighting device, that is, the color temperature of the atmosphere lighting device has changed.

[0102] In another embodiment, by adjusting the light color ratio of the second light source 321 with different color temperatures, the color temperature of the directional lighting device can be adjusted. Specifically, by changing the current of the second light source 321 corresponding to different color temperatures, the light color ratio of the second light source 321 with different color temperatures is adjusted. For example, the current of the cold white light source is 2 mA, and the current of the warm white light source is 3 mA. At this current ratio, a certain color temperature of the directional lighting device corresponds. When it is necessary to change the color temperature, for example, the current of the cold white light source is adjusted to 3 mA, and the current of the warm white light source is 4 mA. At this time, the light color ratio of the second light source 321 corresponding to different color temperatures has changed, that is, the color temperature of the directional lighting device has changed.

[0103] Exemplarily, the illuminance of the directional lighting device is adjusted by changing the current magnitude of the first light source 311 with different color temperatures in equal proportion. For example, the current of the cold white light source is 2 mA, and the current of the warm white light source is 3 mA. At this time, the current ratio of the cold white light source and the warm white light source is 2:3. At this ratio, a certain color temperature and a certain illuminance of the directional lighting device correspond. When only the illuminance needs to be changed without adjusting the color temperature, the currents of the cold white light source and the warm white light source are increased or decreased in equal proportion. For example, the cold white light source is adjusted to 4 mA, and the current of the warm white light source is 6 mA. At this time, the illuminance can be adjusted while keeping the color temperature unchanged. It should be noted that when the currents of the first light source 311 with different color temperatures change non-equally, both the color temperature and the illuminance of the directional lighting device will change.

[0104] It can be understood 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 within a certain time period, and within another time period, the current ratio of the cold white light source and the warm white light source can be changed.

[0105] It can be understood that the illuminance and the color temperature can be adjusted separately or simultaneously.

[0106] In some hospitals, there are no or very few windows facing the natural outside world in wards such as the ICU, and natural light cannot reach the location of the patient 6. Artificial lighting is used throughout the ward. In the ward with artificial lighting, the lighting fixtures are turned on for a long time, and the lighting environment in the whole room is constant, without lighting rhythm changes, which in turn affects the patient 6's own rhythm regulation function, affects the secretion of melatonin in the patient 6, affects the sleep of the patient 6 and medical staff, and may thus be unfavorable to the recovery and physical and mental health of the patient 6, nor is it conducive to the work and physical and mental health of the medical staff.

[0107] To this end, in the embodiments of the present application, the light-emitting mode of the ambient lighting unit includes a rhythm mode. In the rhythm mode, the color temperature and illuminance of the light emitted by the ambient lighting unit change according to a preset rule. In this way, the lighting in the ward presents a rhythmic change. The above 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 ambient lighting unit according to time and the natural illuminance in the current ward.

[0108] In the embodiments of the present application, please refer to Figure 17 , the preset rule is an analog circadian rhythm rule, that is, the corresponding illuminance is determined only according to time. The so-called analog circadian rhythm rule refers to simulating the natural light conditions in 24 hours of a day in nature, which includes color temperature and illuminance information, and forming a database of the corresponding relationship between time and light conditions. Specifically, when the user turns on the rhythm mode, the lighting system obtains the corresponding preset illuminance information and color temperature information in the database according to the current time, and then controls the color temperature and brightness of the ambient lighting unit.

[0109] It should be noted that the directional lighting array 31a may also have a rhythm mode, and its rhythm control rule may be the same as or different from that of the ambient lighting unit, which is not limited herein.

[0110] 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.

[0111] In the embodiment where the lighting mode of the directional lighting device includes a reading mode, the illuminance of the directional lighting array 31a is in the range of 300 lx to 2000 lx, and the color temperature is in the range of 3000 K to 5000 K, and the color temperature remains unchanged. For example, when the patient 6 needs to perform a reading activity on the hospital bed 5, high illuminance lighting is not required at this time, and the above color temperature range and illuminance range can better meet the lighting needs of the patient 6 during reading. It should be noted that in the reading 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.

[0112] In an embodiment where the illumination mode of the directional illumination device includes an inspection mode, the illuminance of the directional illumination array 31a is in the range of 1000 lx to 10000 lx, the color temperature is in the range of 3000 K to 5000 K, and the color temperature remains unchanged. For example, when medical staff needs to examine patient 6, the color temperature and illuminance in the above range are required in the trunk area of patient 6. At this illuminance, medical staff can perform clinical operations such as intubation. It should be noted that in the inspection mode, the color temperature of the directional illumination 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.

[0113] In an embodiment where the illumination mode of the directional illumination device includes a light stimulation mode, the illuminance of the directional illumination array 31a changes gradually, and the highest value of the illuminance is in the range of 2000 lx to 10000 lx, and the color temperature of the directional illumination array 31a remains unchanged. It can be understood that in the light stimulation mode, the light of the directional illumination array 31a can at least project onto the head area of the patient 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 illumination 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.

[0114] For example, when it is necessary to promote patient 6 to wake up from sleep, a time-controllable and high-illuminance area illumination is provided to the head area of patient 6 through part of the first light source 311. Patient 6's eyes can feel the high-illuminance illumination and can wake up from the sleep state. Exemplarily, in one embodiment, in the light stimulation mode, the illuminance in the head area of patient 66 changes gradually within a preset time period. For example, the total sum of the preset light stimulation time periods is 10 minutes to 20 minutes, increasing gradually from no light to approximately 2000 lx to 10000 lx, and then gradually turning off.

[0115] In one embodiment, please refer to Figure 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 an illumination mode on / off key and / or an illuminance adjustment key.

Among them, the wired manner means that the control terminal is electrically connected to the main control board through a cable to transmit the control signal generated by the control terminal to the main control board through the cable. The wireless manner means that the control terminal transmits the control signal to the main control board through wireless transmission technology.

[0116] The specific types of the lighting mode on / off key and / or the illuminance adjustment key are not limited. For example, it can be a physical button, a touch key, a virtual button set on the display screen, etc., and no limitation is made here.

[0117] In the embodiment where the lighting system 3 includes the above-mentioned inspection mode, reading mode, and rhythm mode, please continue to refer to Figure 19 , the lighting mode on / off key includes an inspection mode on / off key 3822, a reading mode on / off key 3823, and a rhythm mode on / off key 3821. It should be noted that a total on / off key 3824 is also provided on the display panel 382, and the total on / off key 3824 is used to control the turning on or off of the lighting system.

[0118] When the user triggers any one of the lighting mode on / off keys, the lighting system 3 can enter the lighting mode matching the lighting mode on / off key.

[0119] In the embodiment where the lighting system 3 includes the above-mentioned inspection mode, reading mode, and rhythm mode, please continue to refer to Figure 19 , the illuminance adjustment key includes an inspection mode illuminance adjustment key 3826, a reading mode illuminance adjustment key 3827, and a rhythm mode illuminance adjustment key 3825.

[0120] In one embodiment, please refer to Figure 18 , the control terminal 38 further includes a rear case 384 and a front case 383. The display panel 382 is disposed on the front side of the front case 383. For example, the display panel 382 can be adhered to the front side of the front case 383 by double-sided tape; the display controller 381 is disposed on the rear side of the front case 383. For example, the display controller 381 can be adhered to the rear side of the front case 383 by double-sided tape. The display panel 382, the front case 383, and the rear case 384 together form a closed space, and the display controller 381 is disposed in the closed space between the front case 383 and the rear case 384. In this way, the charged components can be enclosed in the closed space. Even if the control terminal 38 is not attached to other mechanical devices, the control terminal 38 can be used as a safe module for direct operation by the user without the risk of electric shock.

[0121] In one embodiment, please continue to refer to Figure 18 , the control terminal 38 further includes a button fixing frame 385. The button fixing frame 385 is fixedly connected to the front case 383 or the rear case 384, and the control terminal 38 is connected to mechanical devices, etc. through the button fixing frame 385. For example, connection holes can be provided on the button fixing frame 385, and detachable connection can be achieved through connecting pieces such as screws or bolts.

[0122] It can be understood that, in order to make the installation of the control terminal 38 relatively firm, the button fixing frame 385 surrounds the circumferential direction of the front shell 383 or the rear shell 384, and there are multiple connection holes. The multiple connection holes are arranged at intervals along the edge of the button fixing frame 385, so that the button fixing frame 385 is stressed relatively evenly along the circumferential direction of surrounding the front shell 383 or the rear shell 384, and the installation reliability of the control terminal 38 is improved.
