Can tingle.This phenomenon is medically referred to as light adaptation.If being turned on light in more dim bedroom, a piece of credit is felt in most first meeting
The light of eye, and human eye feels very uncomfortable, it is impossible to see object clearly, if the brightness change of light is very violent, or even occur short
Temporary property blindness could recover vision for a period of time, it is necessary to rest.And in collective livelihood, the lighting demand of a people can be led
Remaining is caused to be waken up in the people in sleeping soundly after by light stimulation, influence sleep.
Research shows that, when being in for a long time under a kind of specific light bright ring border, human eye will adapt to this specific bright environment,
The irradiation of unexpected strong light influences whether the eyesight of people, and the eyes of people need the time to go to adapt to again.Eyes are receiving intense light irradiation
After penetrating, photopigment in eyeball retina and the rhodopsin accumulated in the dark are decomposed rapidly under light, so that regarding
Nethike embrane declines rapidly to the sensitiveness of half-light, photosensitive and recover vision by the relatively low cone pigment of sensitiveness to light later.At this
During individual, occur strong light guide suddenly and cause the pupil of human eye to have little time to reduce, on substantial amounts of intense direct illumination to retina, just
Injury is caused to the cornea and iris of human eye, occurs dysopia in a short time.Therefore, had by human eye during strong illumination
Pain, will could recover normal eyesight after a while.Strong light, which is hindered, also many infants in the case of eye, infant is just
In the visual development stage, cornea is tender and lovely, intense light source irradiation child's eyes, easily causes the property ARM that burns day.Therefore, for a long time
There is strong light stimulus, the eyes of adult and children can be caused forever to be damaged, it is impossible to recover.

Lamp power supply is connected, and switches light control unit by force switch and common lamp opens control electric light.
Wear on the person in sensing region, such as electronic tag, intelligent wristwatch etc., when people enters Perception Area
Domain, and human body activity detector units are worn, physical activity detection unit sends data to controller, informs controller, increase sense
Know the activity number in region, when people leaves sensing region, and take off physical activity detection unit, physical activity detection unit to
Controller sends data, informs controller, reduces the activity number in sensing region.
For example：Define current active number act_per, when wearing human body activity detector units, physical activity detection unit
1, act_per=act_per+1 is sent to controller；When taking off physical activity detection unit, physical activity detection unit is to control
Device processed sends 0, act_per=act_per-1.
Wireless communication module includes the wireless transceiver in wireless transceiver and physical activity detection unit in controller,
By the communication between wireless transceiver, the transmission of data is realized.
Illuminance of the illuminance detection unit to environment in detection senses region, can use luminance detector, perceive
Illumination in region mainly has two parts, and a part is the light that electric light is produced, and another part is the light that other factors are produced.
Force switch is a switching device, can use single-pole double-throw switch (SPDT), not moved end connection lamp power supply, and two are moved
Connection light control unit and common lamp are switched respectively at end, when power supply and common lamp switch connection, then it represents that common lamp
Control electric light is opened, when power supply and light control unit connection, then it represents that light control unit controls electric light.Operationally,
Light control unit can send status information to controller, and such as 0 represents light control unit control electric light, and 1 represents signal light control
Unit does not control electric light.
