Description

A kind of LED illuminator with circadian rhythm regulatory function

Technical field

The utility model relates to a kind of lighting electric equipment, specifically a kind of LED illuminator with circadian rhythm regulatory function.

Background technology

2002, the people such as Berson of U.S. Brown university have found amphiblestroid the 3rd class photosensory cell of mammal, intrinsic sensitization retinal ganglial cells (ipRGC), it is one of ten big sciences discoveries in the world then that this discovery is chosen as by the Science magazine, it was only the idea of the organs of vision for eyes that people have also been broken in this discovery simultaneously in the past, and people start progressively to understand beche-de-mer without spike and a lot of human body biochemical reactions of regulation and control mechanism behind in fact.This class photosensory cell can participate in regulating many human body photo-biological effects, comprises the variation of human body vital sign, and the secretion of hormone and excitement degree also participate in the adjusting of body ' s physiological rhythm simultaneously.

Light is passed to signal the biological clock of human body by this newfound photosensory cell and independent nervous system, biological clock is adjusted the circadian rhythm in a large amount of different physiology processes of human body more accordingly, comprise every day circadian rhythm and season the rhythm and pace of moving things and the secretion of alertness, cortisol and the epiphysin of the body temperature of human body, human body.Hormone cortisol (pressure hormone) and epiphysin (sleep hormone) are playing an important role aspect the liveness of controlling human body and sleep.Wherein cortisol can increase in blood sugar and for human body provides energy, strengthen simultaneously the immune system of human body; But when the hormone cortisol is in too high level for a long time, the people knows from experience fatigue and the inefficiency that becomes.Morning, the hormone cortisol levels of human body can increase, for the forthcoming day's activities of human body is prepared.The hormone cortisol is all keeping higher level in whole daytime active procedure, and the time-division at midnight is down to minimum level.The level of sleep hormone epiphysin can descend in the morning the time, to reduce sleep; And can rise once again when environment is dimmed, to impel healthy sleep (cortisol is in floor level).The circadian rhythm of human body should too much not upset, and this is very important for good health.When the circadian rhythm of human body got muddled, early morning, bright light can help to recover normal circadian rhythm.In the situation that nature, light (the especially light in early morning) makes the biological clock of inside of human body be synchronized with 24 hours bright-dark cycle cycles of the earth.

Lack " normally " bright-the dark cycle rhythm and pace of moving things can cause the activity of human body and the confusion of sleep, will cause finally human body at very active of time-division at night, and very drowsiness by day.Also there will be same symptom, the i.e. time difference phenomenon when for the same reason, airplane is done the long-range flight of crossing over several time zones; The staff who works in three shifts also has same experience, there will be this symptom in two days after each break tour.Circadian dysregulation is serious, also can cause digestive system, nervous system, the deterioration of immune system etc., and the final risk of suffering from malignant tumour that increases.Afterwards, scientist also finds according to the impact of light on body ' s physiological rhythm, adopt suitable light radiation can effectively treat seasonal emotional maladjustment (SAD) and Out of season emotional maladjustment (Non-SAD), can effectively alleviate the irregular problem of old dementia patients sleep, can also help simultaneously night work person and long-range flight personage to readjust the time difference, adapt to new circadian rhythm.

So in some sealing or semiclosed place, and provide the lighting environment that is complementary with body ' s physiological rhythm to be conducive to luminous environment experiencer's physical and mental health under the poor environment of natural lighting.
