Abstract
The invention discloses the material with anti-blue light function and using the protective film of the material.Material with anti-blue light function includes high-index material and low-index material, which includes Cr2O3, which includes SiO2, MgF2, HfO2, TmF3, TiN, ThF4, TbF3, Y2O3, TaN, SmF3, ScF3, PrF3, NdF3, Na3AlF6, MgO, LaF3, LuF3, Al2O3,Y2O3, BaF2, CaF2, LiF, HoF3, HfF4, GeO2, YF3, YbF3, CeF3, GdF3, A2O, Gd2O3, EuF3, Bi2O3, AlON, ATO, NdF3, WO3Or at least one of their mixture.It has the following advantages: the material of the technical program under conditions of not destroying colour balance, reduces harmful blue light, and guarantee the transmitance beneficial to blue light and remaining visible light wave range, while reducing the residual reflection of entire visible light wave range.
Description
Technical field
The present invention relates to a kind of optical material more particularly to a kind of material with anti-blue light function and apply the material
Protective film.
Background technique
Blue light is the important component of available light, blue light harm refer to by wavelength between 400 to 500nm spoke
After penetrating light irradiation, retinal damage caused by caused photochemical effect.The feel realized along with consumer " blue light protection "
It wakes up, blue light protection has obtained the concern of the majority of consumers.Display screen or lighting system currently on the market often uses white light
LED realizes that most common mode is to add the mode of YAG fluorescent powder to realize with gallium nitride blue light-emitting.The radiation of blue-ray LED
Spectral intensity focuses primarily upon 400-500mm range, especially has very strong radiation intensity in low energy blue wave band.Due to
Wavelength is shorter, and energy is then stronger, thus the greenish-yellow feux rouges of energy ratio of short wavelength's blue light is much better than, therefore its injury to human eye
Also just much bigger.It is shown according to correlative study, photooxidation reaction can be accelerated by being exposed in the blue light that wavelength is 425nm or so, be drawn
It sends out eye ground and starts photooxidation mechanism, which is that the damage of retinal pigment epithelium Mitochondria DNA is caused to be
The main mechanism of macula retinae portion lesion (AMD) morbidity；And blue light is also the adjuster of biological clock simultaneously, is had clear
Evidence shows that blue light is an important factor for stimulation brain discharges epiphysin, and epiphysin is that human body adjusts the important of biological clock
Index, therefore blue light (mainly 460nm wave band) plays indispensable role to human body.Therefore, anti-blue light should not destroy
Under conditions of colour balance, reduction harmful blue light (415nm-455nm) as far as possible, and guarantee to greatest extent beneficial to blue light
The transmitance of (455nm above band).
It can learn that blue light barrier optical filter is helpful to teenager according to investigation, and can be used as a kind of cope with and arrange
It applies, the high dose blue light light that barrier LED screen issues, reduces negative effect of the modern illumination to night physiological system.Therefore
It needs to do such equipment certain protected working, reduces injury of the blue light to human body.
Blue light prevention and treatment on, mainly start with both at home and abroad from two technology paths, one is use coloring mode, by
The absorbents such as black essence, yellow essence, azo permanent yellow dyestuff, azo forever solid orange dyestuff are added in anti-blue light film layer, it can mistake
Filter most of high energy shortwave blue light.But this method has stronger absorption to 400nm to 500nm wave band even all band, uses
The anti-blue light protective film of this method manufacture, influences the color sensitivities of wearer, color error ratio occurs, applicability is relatively low, simultaneously
It is used for a long time, eyesight chromatic aberration can be caused, cause the puzzlement of other visions；In the patent text that publication No. is CN104476874B
In part, describes and anti-blue light protective film is prepared using the method for coloring.It can be seen that absorbent added by this method
Dosage is not easy to control, is also unfavorable for producing in batches.
Another anti-blue light product most common on the market takes reflective technology path, that is, uses optical coating side
Formula realizes that shortwave is high anti-by principle of interference between film, and preparation has blue wave band 415nm-455nm high reflectance, 470nm-
The dielectric multi-layer optical thin film of 760nm high transmittance is realized.To realize the portion for the blue light being at 400nm-480nm to wavelength
Divide the function of barrier.Blue light maximum radiation wavelength 400nm-450nm reflectivity reaches 50%, wavelength 460nm-480nm reflection
Rate reaches 40% or so.For this method for obstructing blue light by reflective, although display screen blue wave band can be obstructed
Transmitance, but have ignored the influence of external environmental light.The most common external environmental light is daylight, since film layer has blue light
The high anti-structure of wave band, thus it is very strong to the blue light ingredient reflection in environment light.More importantly outer surface is excessively bright
Blue violet light reflection can also generate the uncomfortable secondary blue light such as dazzle to surrounding population and injure.It is in publication No.
