Description
Technical field
The present invention relates to lighting technical field, and in particular to a kind of dynamic lighting method, especially suitable for reading and writing operation ring
The expectation such as border and house lighting environment produces the occasion of sight protection and/or visual training.
Background technology
Vision Health also has become a major issue of people's common concern.According in June, 2015 Peking University
State's sound development research center《National health visual report》Research, in more than the 5 years old total population in China in 2012, China's myopia
It is mostly student and working clan with long sight diseased colonies.The number of patients about 500,000,000 of myopia and long sight, wherein total ill people of myopia
Number is 4.5 hundred million or so.Students ' Learning pressure is big, and homework is more, to read a book, do one's assignment under light for a long time at night, and uses
Ocular hygiene is again very unhealthy, and it is a undeniable factor to cause eyes chronic fatigue.In addition to student, working clan et al.
Group also reads a book, reads and worked under light for a long time, and eyes suitably cannot rest and adjust, along with due to illumination
Association of section does not make eyes hair shaft, turns sour, be dizzy, headache, or even nausea, nervous, tachycardia, has unawares suffered from " lamp
Light fatigue syndrome ".In addition, improper illumination may be injured to caused by eyes and disease includes：Photic cataract, photic view
Film inflammation, photokeratitis, myopia, the disorder of brain eye function, dazzle formula visual fatigue etc..
In the prior art, the occasion of generation sight protection and/or visual training, the illumination side that lighting device uses it is expected
Method is broadly divided into two kinds：Independent illumination mode and floor light mode, wherein independent illumination mode are to choose lighting device itself
Light source parameters realize the method for the illumination with sight protection effect, and floor light mode is based on ambient light or natural light
Participate in realizing the means of illumination with sight protection effect.

Change be not enough to produce visual perception and be enough the influence discovered, but can make user's eyes iris will user without
The size of active accommodation pupil on the premise of consciousness, so as to control luminous flux.So, iris just follows the continuous change of illumination light
And move.The athletic meeting of iris drives ciliary muscle movement, and the motion of ciliary muscle will also drive lenticular motion, so as to produce
In raw visual field so-called " eyes link depending on photosystem three ", so as to reach the purpose for tempering user's eyes.
Determine to control the electric parameter of the lighting parameter according to required obtained lighting parameter.Such as table 1 below, table 2,
Table 3 be respectively electric parameter transformation period section be in the case of 10 seconds, 100 seconds, 250 seconds several groups of different initial illumination and it is different when
Between the brightness value put, table 4, table 5, table 6 are that electric parameter transformation period section is several in the case of 10 seconds, 250 seconds, 250 seconds respectively
The brightness value of the different initial illumination of group and different time points, the brightness value excursion meet：Lighting parameter in the range of 0.1 second
Excursion between about 1.001 to 1.02.
