Myopia refers to external light, after dioptric system (mainly being cornea and the crystalline) flexion of eyeball, does not focus on the retina accurately, but drops on before the retina, makes blurring of vision clear.Though and the reason that causes myopia has the factor of a lot of aspects, but be subjected to the external environment factor and cause the near-sighted major part that accounted for, the not science of lighting source and cause eye muscle to be in fatigue state for a long time and then the decline that causes its regulatory function more should attract much attention wherein, this be because the decline of eye muscle regulatory function can directly to have influence on the adjusting of eye refraction system not in place and then cause myopia.

At present, general idea is thought, study or work are a kind of modes of eyeshield (myopia prevention) under the more moderate and comparatively stable illumination at light, we can see from the recommendation for the regulation of standard illuminants and standard sources of international standard illumination association (CIE), and making light source requirements for the best is exactly the natural daylight (is ideal light source in 8 o'clock to the 10 o'clock morning in the most of area of China and the available light in 3 o'clock to 5 o'clock afternoon) that can simulate special time to greatest extent; To this, Patent Office's notification number is that CN2405114Y " multi-functional full-automatic myopia prevention desk lamp " by name discloses a kind of eye-protecting desk lamp, the document has been put down in writing the brightness of showing up for light stable a circuit with an automatic light meter has been set, can be according to the bright brightness of secretly and automatically regulating of plane of illumination, guaranteeing has comparatively stable illuminance on the plane of illumination, and reaches myopic-preventing purpose with this.This is a kind of general knowledge, but people have also ignored a trifle simultaneously, lack in eye exactly and a kind of eye muscle is forged experienced consciousness, promptly normally just regulate eye muscle by mode such as close one's eyes or look in the distance after feeling fatigue with eye, this also is the common fault that has eyesight protection lamp now.

As everyone knows, human eye pupil when seeing thing can change along with the power of light, but pupil is also just relatively stable when your long-term relative fixed is seen thing under certain environment, in the course of time, the muscle that is used for regulating the iris of pupil will produce fatigue and influence its regulatory function, and then causes the decline of eyesight.In view of this, the applicant thinks, sight protection is from eye-using environment, the light source of simulating nature light guarantees that promptly a suitable illuminance is no doubt important, but obviously, angle from the eye muscle health care, the brightness that changes plane of illumination impels the contraction of pupil and takes this to alleviate eyes muscular fatigue, and make phaeochrome cell seem more active by the variation of colour temperature, make optic nerve more excited, the dioptric system of having guaranteed whole eyeball can be in the good working environment, this for sight protection, prevent that eyesight from descending and also be very important.

Summary of the invention

The purpose of this utility model is to disclose a kind of eyesight protection lamp of simulating dynamic natural light, has impelling eye muscle to keep healthy with nationality in the eye work by the variation of light to forge experienced function, reach and alleviate eyes muscular fatigue and the purpose of eyeshield.

In order to achieve the above object, the utility model adopts following technical scheme: a kind of eyesight protection lamp of simulating nature light, the light source that comprises colour temperatures different more than two or two, each light source is respectively joined the control circuit of its brightness of control, it is characterized in that described control circuit can control the brightness of light source automatically, the brightness and the colour temperature of the illumination light after making light source more than two or two compound ceaselessly change in suitable illumination zone.

The light source of described each different-colour is made up of a lot of little illuminators, and with the evenly distribution alternately of little illuminator of the light source of other different-colour.

Described suitable illumination zone is to allow the illumination of its face to be illuminated in the scope of 400LX to 1000LX, and the suitable illumination zone of colour temperature then is to be that to change paramount value be 5000K-6000K to 3000K-4000K from low value.

The utility model compared with prior art has following advantage after adopting technique scheme: 1, adopt the light source simulating nature light more than two or two to carry out compound, the brightness of light source reaches 400LX-1000LX, colour temperature reaches 4000K-5000K, the condition that meets the standard sources that the international luminous lighting committee (CIE) recommended, for human eye create one as snug as a bug in a rug use luminous environment.

2, regulate the brightness of light source and the variation of colour temperature by control circuit, further simulate dynamic natural light, impel illuminance to remain on to produce light under the situation of certain comfort level to change.Be the bright dark variation of light-source brightness on the one hand, impel the contraction or the expansion of pupil, and take this and impel the muscle in the iris to regulate, make eye muscle unfold contraction naturally, avoid the decline that under a certain state, produces tonus of ocular muscles or spasm because of fixing for a long time and cause its regulatory function, alleviate kopiopia effectively.Be the variation of light source color temperature on the other hand, it stimulates the active of amphiblestroid phaeochrome cell effectively, and then the excitement that has kept optic nerve, and the degenerative that delays the eyes Color Appearance System is had positive effect.
