Description
Technical field
The present invention relates to a kind of LED eye-protecting lamps.
Background technology
Existing eye-protecting lamp includes：High-frequency lamp, the alternating current of China Power Grids is 50Hz, i.e., per second to change 50 times.So straight
Connect the fluorescent lamp using alternating current（Fluorescent lamp）, bright to have flicker, flicker frequency is 100 times/second, is 2 times of mains frequency.
The Main change that human eye can be perceived is within 30Hz, though alternately change will not be perceived the light and shade of 100 times per second of light by us,
These flickers have an impact for human eye.During such as light, pupil can shrink in eye；During brightness, pupil can amplify.So directly with friendship
The fluorescent lamp of stream electricity has injury for eyes.High-frequency lamp（Such as common energy-saving lamp）Middle use frequency-variable electronic device, by 50Hz alternating currents
Become high-frequency alternating current（Usually 30k-50kHz）, then use high-frequency alternating current lighting.In high-frequency lamp, light change per second is several
Ten thousand times, because human eye has little time to change therewith, just imperceptible change, thus be exactly " constant ", reach the purpose of eyeshield.It is high
The drive circuit of frequency lamp has 30-50kHz electromagnetic signal, and someone claims that this is harmful, but without specific report or
Number is it was demonstrated that must further study, examine.A lot " eye-protecting lamps " on the market, are exactly the fluorescence using electron rectifier in fact
Lamp, spoken parts in an opera is exactly some electricity-saving lamp.The characteristics of its is main is no stroboscopic, for this is with respect to fluorescent lamp.Eye-protecting lamp utilizes height
Power frequency is adjusted to 30k-50kHz by band electronic rectifier, and optical flare speed is very fast；And because the twilight sunset of fluorescent material is imitated
Should, light amplitude of variation is obviously reduced, therefore human eye fundamental sensation is less than the flicker of light, feels it is stable.But strictly
Come, electricity-saving lamp is not definitely the but high stroboscopic by a small margin without stroboscopic.Exactly this feature, the light that it is sent compares daylight
It is more stable more comfortable for lamp.
LED desk lamp, using power supply adaptor, illumination is mainly used in large-scale landscape illumination or some will to light quality
Not high occasion is sought, high eye-using environment is poorly suitable for, because blue light strength is high, eyes are easily hurt.Small lamp bulb is easily lost,
The problem of there is attenuation rate, easily causes whole desk lamp and scraps, universal illuminating area is small, and chromatogram is narrow, belongs to monochromatic source,
Optic nerve can be affected, it is relatively dazzling.But LED desk lamp also has its advantage, opposing electronic original paper cost
Low, whole lamp is cheap.LED colour temperature has warm white（It is a little partially yellow, 2700-3000k or so）, it is just white（4500-6500k）And
Cool white (6500-12000k）Three classes.The LED of cool white is relatively dazzling.
Direct current eye-protection lamp, using DC ballast, by alternating current being first transformed into the stable direct current of voltage, electric current,
Direct current lighting is used, is reached substantially without stroboscopic, and the light sent when using is the light of continuous uniform as natural light, it is very soft
Be avoided that asthenopia, and solve the stroboscopic problem of Inductive ballast fluorescent lamp；Due to using DC techniques, nothing
Any AC ripple, it also avoid as the electromagnetic interference signal caused by electric ballast.
Current existing LED eye-protecting lamps in-convenience in use, structural strength is not high, carries inconvenient.
The content of the invention
In view of this, it is an object of the present invention to provide a kind of easy to use, structural strength height, LED eye-protecting lamps easy to carry.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of LED eye-protecting lamps, including base plate, rotating shaft,
