Description
Technical field
The present invention relates to photosensitive algorithmic technique fields, and in particular to a kind of automatic brightness adjustment side based on photosensitive algorithm
Method.
Background technique
With the development of society, the progress of science and technology, the quantity of study of student knowledge is being stepped up, the operating pressure of people
It is being gradually increased, prolonged study and work, so that people are very serious with the situation of eye ill-health.Minor's myopia
Ratio, the ascendant trend of large scale year by year is presented, the probability for also making adult have eye trouble rises, so living breath breath with people
Relevant lighting problem has been to be concerned by more and more people.Lamp used in current illumination has traditional incandescent lamp bulb, energy-saving lamp
, fluorescent tube, desk lamp is also in this way, all having that light quality is poor, and brightness is unstable, and unadjustable, stroboscopic, shake makes
Human eye is uncomfortable, visual impairment, especially influences on minor very grave.
Summary of the invention
In view of the deficiencies of the prior art, the present invention reads according to light sensation and changes, and the brightness degree of adjust automatically LED light makes ring
Border overall brightness maintains suitable range, is conducive to the eyes for protecting user, the ratio of myopia is effectively reduced.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of automatic brightness adjustment method based on photosensitive algorithm, which comprises the following steps:
S1 obtains current LED luminance curled and light sensation reading curlux at regular intervals；
S2, setup parameter A, the calculation of parameter A: a=(this light sensation reading-last time light sensation reading)/(this LED
Lamp brightness degree-last time LED light brightness degree)；
S3 finds out current goal brightness degree targetled using curled, curlux and parameter A；
S4 compares curled and targetled size, and makes the LED luminance adjustment of adaptability, until curled is equal to
Targetled exits adjusting.
Further, in the step S1, every 150ms obtains current LED luminance curled and light sensation reading
curlux。
Further, in the step S3, every 8s utilizes curled, curlux and parameter A, finds out current goal brightness etc.
Grade targetled.
Further, in the step S4, if curled is equal to targetled, continuation is inquired next time, does not need to adjust
It is whole.
Further, in the step S4, if curled is greater than target, every 200ms reduces the brightness of a lattice LED light
Until grade is consistent with targetled.
Further, in the step S4, if curled is less than target, every 200ms increases the brightness of a lattice LED light
Until grade is consistent with targetled.
Further, in the step S2, in order to make a close to reality, the average value of multiple a is taken.
Further, since parameter A and actual capabilities deviation are somewhat big, so value a ∈ [1,50], a when going beyond the scope
=1.
Further, in the step S3, the calculation of targetled is templux=(curlux-a*
curled)。
Further, the targetled ∈ [10,60].
Further, it if templux ∈ [400,1000], targetled are fallen in the section of [30,60], is rounded,
Targetled=60- (templux-400)/20；
Further, it if templux ∈ [1000,2000], targetled are fallen in the section of [10,30], is rounded,
Targetled=30- (templux-1000)/50；
Further, if templux > 2000, targetled=10；
Further, if templux < 400, targetled=60.
A kind of beneficial effect of automatic brightness adjustment method based on photosensitive algorithm provided by the invention is: the present invention can
To be applied to the lamps and lanterns that desk lamp etc. can be applied to LED light, adaptation orientation is wide, can be read and be changed according to light sensation, adjust automatically LED
The brightness degree of lamp makes environmental complex brightness maintain suitable range, is conducive to the eyes for protecting user, is effectively reduced close
Depending on the ratio of eye.
Detailed description of the invention
Fig. 1 is the method for the present invention flow chart.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Whole description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Ability
Domain ordinary person every other embodiment obtained without making creative work, belongs to protection of the invention
Range.
A kind of embodiment: automatic brightness adjustment method based on photosensitive algorithm.
A kind of automatic brightness adjustment method based on photosensitive algorithm, which comprises the following steps:
S1, every 150ms obtain primary current LED luminance curled and light sensation reads curlux；
S2, setup parameter A initial value are 27, the calculation of parameter A: a=(read by this light sensation reading-last time light sensation
It is several)/(this LED light brightness degree-last time LED light brightness degree), and it is real in order to approach a, the average value of multiple a is taken, by
It is somewhat big in parameter A and actual capabilities deviation, so value a ∈ [1,50], a=1 when going beyond the scope；
S3, every 8s utilize curled, curlux and parameter A, find out current goal brightness degree targetled,
The calculation of targetled is templux=(curlux-a*curled), targetled ∈ [10,60]；
If templux ∈ [400,1000], targetled are fallen in the section of [30,60], it is rounded, targetled=
60-(templux-400)/20；
If templux ∈ [1000,2000], targetled are fallen in the section of [10,30], it is rounded, targetled
=30- (templux-1000)/50；
If templux > 2000, targetled=10；
If templux < 400, targetled=60；
S4 compares curled and targetled size, if curled is equal to targetled, continuation is inquired next time, no
It needs to adjust；
If curled is greater than target, every 200ms reduces the brightness of a lattice LED light until grade and targetled mono-
It causes, exits adjusting；
If curled is less than target, every 200ms increases the brightness of a lattice LED light until grade and targetled mono-
It causes, exits adjusting.
The above is presently preferred embodiments of the present invention, but the present invention should not be limited to embodiment and attached drawing institute public affairs
The content opened both falls within protection of the present invention so all do not depart from the lower equivalent or modification completed of spirit disclosed in this invention
Range.
