Background
Currently, with the rise of the living standard of people, people are more and more focused on health, wherein health illumination is a topic of great interest in the current illumination field. The health illumination is illumination which is based on visual and non-visual effects, improves the quality of light environment and is beneficial to the physiological and psychological health of people. The home health lighting system is mainly used in two places commonly used by users such as living rooms and bedrooms. Now, the phenomenon of minority-fold is prominent due to the decline of global fertility level. Families pay great attention to all aspects of physical and mental health of children, and special children rooms are arranged for the children in many families for the children to learn, entertain and play and rest. The children's house becomes a very important lighting place in the healthy growth of children, and many parents can make many individualized decorations and decorations to the room according to children's hobbies in children's house to place children's furniture and toy. However, the prior art has relatively few aspects of health lighting research or technical innovation on the aspect of the children's houses, and is not intelligent technically. As in the prior art, korean patent KR101334212B1 discloses a child house management system, which discloses color and brightness control for lighting required for patterns in which a child is located in a child house, which are classified into a learning mode, a resting mode, a sleeping mode, etc., and different lighting schemes are used in different modes. However, the above prior art only uses a fixed illumination scheme around the characteristics of the child when the child is in various modes, and is not combined with the environmental characteristics of the child's house where the child is located.
Also chinese patent CN108055745a discloses a lighting system suitable for a child room, which comprises a controller, a photoelectric coupler, a bulb, a power supply, a first variable resistor, and a compensation unit, wherein the input end of the controller is connected with the power supply and the photoelectric coupler, the output end of the controller is connected with the first variable resistor, and the compensation unit is connected between the controller and the bulb. The controller controls the first variable resistor to adjust the light to a comfortable brightness, when the power supply voltage changes, the brightness of the bulb changes, the photoelectric coupler senses the change of illumination intensity, the illumination intensity at the moment is converted into a current signal, the current signal is transmitted to the controller, the controller readjusts the first variable resistor, so that the brightness of the bulb is recovered, the problem that the traditional light system can change due to the change of the voltage, the too high and too low voltage can cause the lamp to be too bright or too dark, and eyes of people are injured, and vision is affected is solved. This only considers the effect of voltage variation on the eyesight of children from a hardware perspective, and such hardware improvement does not consider the behavior state variation of children in the children's houses, and the light source adjustment is realized manually through a variable resistor.
In addition, CN211959615U discloses an intelligent healthy lighting system for children's room, including the illumination lamps and lanterns, the illumination lamps and lanterns include the casing and install at the inside lighting module of casing, leave the distance between lighting module and the casing luminous end and form the optical filtering chamber, be provided with the filter membrane that is used for filtering the blue light and be used for fixed filter membrane's fixed subassembly in the optical filtering chamber.

From fig. 2, 3 and 4 in turn, the change of behavior state of the target child 1 in the child's room can be seen. During entertainment, the mood of the child can be relaxed, and the illumination parameters can be properly adjusted to the first illumination brightness and the first color temperature, so that the light source can set the atmosphere. The first illumination brightness and the first color temperature may be warm colors, such as about 3000K to 3500K, and the brightness is brighter. When a target child learns, the illumination parameters can be adjusted to the second illumination intensity and the second color temperature, the child can concentrate on learning, the second color temperature can be adjusted to 5500K-6000K, 6000K is better in cold white, when the child is at rest, the child can be adjusted to about 4000K and is close to natural light, preferably, the natural light at the moment is consistent with outdoor natural light as much as possible, and thus the biological rhythm of a human body is more met. And when the child has a rest to a sleep state, the light source is automatically turned off.
