Description

"LIGHTING SOURCE TO STIMULATE THE CIRCADIAN CYCLE".

FIELD OF APPLICATION This model describes a light source for environments comprising different light combinations, which can be designed so that the user can enjoy the appropriate light source at each period of the day, enabling activities while respecting the circadian cycle. The present invention is in the field of architecture, engineering and lighting. Background of the Invention The circadian cycle is an internal mechanism capable of adjusting the biological clock, designating the period of approximately 24 hours on which the entire cycle of the human body and any other living being, influenced by sunlight, is based. Living things have a brain-centered control mechanism where the pineal gland regulates various functions and determines how often they should take action, and appetite and sleep can be cited as examples. The term circadian originates from Latin, more specifically circa diem, which means about one day.

Sleep circadian rhythm disorders are changes in biological clock times and changes in the sleep cycle. These disorders can cause symptoms of insomnia at certain times, drowsiness at other times, fatigue, lack of mood, attention problems, concentration problems, among others. The essential feature of sleep circadian rhythm disorder is a persistent or recurring pattern of sleep disorder that results from a mismatch between the individual's endogenous circadian sleep-wake system, and exogenous demands regarding sleep time and duration. The present invention describes innovative ambient light source, which has different light combinations suitable for each period of the day, enabling activities to be performed and respecting the circadian cycle.
