It should be noted that the second light source 321 may adopt the circuit connection manner of the above-mentioned embodiments of the first light source 311, and certainly, the second light source 321 may also adopt other circuit connection manners, which is not described herein again.

In an embodiment, some of the second light sources 321 in all the second light sources 321 are cool white light sources, and another part of the second light sources 321 are warm white light sources, and during the operation of the ambience lighting device, the ratio of the number of turned-on cool 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 cool white light sources to the warm white light sources is different in at least two time periods.

The color temperature of the overall light of the ambience 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 the turned-on second light sources 321 with different color temperatures, for example, the number of the turned-on cold white light sources is 12, the number of the turned-on warm white light sources is 12, and the ratio of the number of the turned-on second light sources 321 with 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 the cold white light sources and the warm white light sources is adjusted, for example, the number of the cold white light sources turned on is 10, the number of the warm white light sources turned on is 12, at this time, the ratio of the number of the second light sources 321 turned on of the two color temperatures is 5:6, and at this time, the color temperature of the corresponding atmosphere lighting device, that is, the other color temperature of the atmosphere lighting device, has been changed.

In another embodiment, the color temperature of the directional lighting device can be adjusted by adjusting the color ratio of the second light sources 321 with different color temperatures. Specifically, the light color ratio of the second light sources 321 with different color temperatures is adjusted by changing the current of the second light sources 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, and the current ratio corresponds to one 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 proportion of the second light source 321 corresponding to different color temperatures has been changed, that is, the color temperature of the directional lighting device has been changed.

Illustratively, the illuminance of the directional lighting apparatus is adjusted by changing the current levels of the first light sources 311 with different color temperatures in equal proportion, for example, the current of the cold white light source is 2mA, the current of the warm white light source is 3mA, and the current ratio of the cold white light source to the warm white light source is 2:3, which corresponds to one color temperature and one illuminance of the directional lighting apparatus, and when only the illuminance needs to be changed and the color temperature does not need to be adjusted, 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 4mA, and the current of the warm white light source is 6mA, and then the illuminance can be adjusted while keeping the color temperature unchanged. It should be noted that when the currents of the first light sources 311 with different color temperatures change in an unequal proportion, both the color temperature and the illuminance of the directional lighting device change.

It will be appreciated that during operation of the ambience lighting device, the ratio of the number of cold white light sources turned on to the number of warm white light sources turned on may be varied during a certain time period, and the ratio of the currents of the cold white light sources as well as the warm white light sources may be varied during another time period.

It is understood that the illumination and color temperature can be adjusted individually or simultaneously.

In some hospitals, wards such as ICU have no or few windows facing the outside, natural light cannot reach the position of the patient 6, and the whole ward adopts artificial lighting.

For this reason, in the embodiment of the present application, the light emitting pattern of the atmosphere lighting unit includes a rhythm pattern in which the color temperature and the illuminance of the light emitted by the atmosphere lighting unit are changed according to a preset rule, so that the lighting in the ward exhibits a change in rhythm. The preset rule can be that the corresponding illumination is determined only according to the time, and the color temperature and the brightness of the light emitted by the atmosphere lighting unit can also be determined comprehensively according to the time and the natural illumination in the current ward.

In the embodiment of the present application, please refer to fig. 17, the preset rule is a simulated circadian rule, that is, the corresponding illumination is determined only according to time.

For example, when the medical staff needs to perform examination on the patient 6, the color temperature and the illuminance within the above-described range are required in the trunk area of the patient 6, and the medical staff can perform clinical operation such as intubation. It should be noted that, in the inspection mode, the color temperature of the directional illumination array 31a is not changed, and the illumination is not limited, that is, in some embodiments, the color temperature cannot be adjusted, but the illumination can be adjusted, and in another embodiment, neither the illumination nor the color temperature can be adjusted.

It will be appreciated that in the light stimulation mode, the light rays of the directional illumination array 31a are projected at least onto the head region of the patient so that the patient's eyes can perceive the illumination. It should be noted that, in the light stimulation mode, the color temperature of the directional illumination array 31a is not changed, and the illumination is not limited, that is, in some embodiments, the color temperature cannot be adjusted, but the illumination can be adjusted, and in another embodiment, neither the illumination nor the color temperature can be adjusted.

For example, when it is necessary to promote the patient 6 to wake up from sleep, the time-controllable high-illuminance region illumination is provided to the head region of the patient 6 by the partial first light source 311, so that the eyes of the patient 6 can feel the high-illuminance illumination, and the patient can wake up from sleep. Illustratively, in one embodiment, in the light stimulation mode, the illumination of the head region of the patient 66 is gradually changed for a predetermined period of time, for example, the sum of the predetermined light stimulation periods is 10 minutes to 20 minutes, gradually increased from no illumination to about 2000lx to 10000lx, and then gradually extinguished.
