Description

Control method of lighting system

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

In the past ten years, it can be understood that the light radiation given to human subjects through the eyes is of great importance in controlling various biological rhythms. In this sense, the knowledge of human photobiology has greatly increased. As a result, optical radiation not only affects many physical functions, but also affects mental performance and mood. In addition, with the continuous improvement of living standards, people have higher and higher requirements for sleep quality, and try to ensure healthy sleep as much as possible under the premise of paying attention to sleep quality. When resting in some family rooms or medical dormitory rooms, two or more people share a room. If a person needs to wake up at night, he must turn on the lights in the room to illuminate. At this stage, the lights or table lamps in the room The brightness is higher, and once turned on, it will inevitably affect the rest of others. On the other hand, when the human body just wakes up from sleep, if it receives strong light exposure, it will easily cause dizziness and blackening in front of the eyes, which is not only not conducive to the health of the human body, but even poses a certain danger to personal safety.

In terms of sleep, delayed phase means that you cannot fall asleep during normal bedtime, but you cannot get up during normal wake-up time. Patients usually fall asleep late in the morning, and can not get up when they usually get up (6-7 am), so that they can not meet the routines of life like going to work or school. Once the patient is reluctant to get up in accordance with the routine of life, he will feel quite drowsy and the brain is unclear. The severity of the symptoms depends on the phase delay and the degree of sleep deprivation. Even if the patient tries to fall asleep early, he can't fall asleep. He needs to lie in bed for a long time to fall asleep. Therefore, patients often misunderstand that insomnia leads to late sleep and wake up late.

Therefore, it is necessary to provide an improved control method of the lighting system to solve the problems in the conventional technology.

It should be noted that the human physiological cycle is determined by internal factors and external factors. The so-called internal factors refer to the genes that control the physiological clock (clock gene), while the external factors include light and non-light stimulation. In mammals, the suprachiasmatic nucleus is responsible for controlling the physiological cycle, such as the awake cycle, body temperature control, etc., and light can generate nerve conduction to the suprachiasmatic nucleus by stimulating the retina, thus affecting the physiological cycle. The suprachiasmatic nucleus can also send nerve conduction to the pineal gland and affect the secretion of melatonin, so melatonin will be reduced after illumination.
