Description

Control method of lighting system

The invention relates to a control method, in particular to a control method of a lighting system.

In the past decade, it can be understood that the light radiation given to human subjects through the eyes is of great importance in controlling various biological rhythms, and in this sense, the knowledge of human photobiology has increased significantly. As a result, light radiation not only affects many physical functions, but also affects mental performance and mood. Furthermore, with the continuous improvement of living standards, people have higher and higher requirements for sleep quality, and try to ensure healthy sleep under the premise of paying attention to sleep quality. When resting in some family rooms or medical dormitories, two or more people share the same room. If a person needs to wake up at night, he must turn on the lights in the room to illuminate, and the lights or table lamps in the room are currently at night. The brightness is high, once it is turned on, it will affect the rest of others. On the other hand, when the human body just wakes up from sleep, if it is exposed to strong light, it is prone to vertigo and blackness in front of the eyes, which is not only harmful to human health, it may even cause some danger to personal safety.

In terms of sleep, phase delay means that you can't fall asleep during normal sleep time, but can't get up during normal wake up time. Patients usually fall asleep late to early in the morning, and cannot get up when they usually get up (6-7 am), so that they cannot meet the daily routines such as going to work and school. Once Patients barely get up in order to comply with daily life, they will feel quite lethargic, their brains are unclear, and the severity of symptoms depends on the delay of the phase and the degree of sleep deprivation. Patients cannot fall asleep even if they try to fall asleep early. They need to stay in bed for a long time to fall asleep. Therefore, patients often mistakenly believe that insomnia leads to late sleep and late awake.
