Fig. 8 and Fig. 9 are please referred to, the spectrogram and light of the quasi- natural light that the LED light source provided through this embodiment generates
Test data is composed it is found that the spectrum meets the spectrum parameter of above-mentioned feux rouges, green light and blue light.Meanwhile in spectrum blue light ratio
It is lowered, also helps health while close to natural light.In lighting area, according to the rule of a large amount of conventional white light illumination
Rule, white light colour temperature is higher, and the ratio of shortwave long component is higher.Figure 10 and Figure 11 are please referred to, conventional lighting sources are usually high color temperature
The white light of high blue light, and near-nature forest light spectrum and natural light spectrum still gap are larger, blue light ingredient is higher, while in feux rouges portion
Point and green light part also have it is clearly disadvantageous.
Blue light is that will lead to macular disease in the latter half of of eyeball to the injury of eyes.Because blue light can accelerate view
The photosensory cell of macular area in film and the oxidative pressure of retinal pigment epithelium and cause to damage, and both cells are all
It is non-renewable, once will affect vision and irreversible after damage, it is serious to even result in blindness.Wound of the blue light to eyes
Evil, it is especially obvious to the inpairment of vision of minority student and children, it will lead to children's anomalous trichromatism, reduce children distinguishes color energy
Power, and lead to the soaring of minor's rate of myopia.Therefore ratio extremely being closed with eye health for maintenance user of blue light is reduced
It is important.
The present embodiment is at least had using above-mentioned LED light source 20 as low color temperature LED light source 21 and high color temperature LED light source 22
Have it is following the utility model has the advantages that
(1) light that LED light source 20 issues is more nearly natural light, illuminates compared to conventional white light, blue light is lower, visual impression
By more comfortably, be conducive to protection eyesight, especially child and children's vision, also help reduction since blue light is excessively high caused
Inferior health problem.
(2) blue light relative spectral power can be controlled in the case where keeping high color temperature and be in reduced levels, can take into account shield
Eye and the purpose for promoting visual effect and improvement user's state of mind.
(3) green light relative spectral power is improved while reducing blue light, solves and is deposited for a long time in the research of near-nature forest light
The relatively low problem of green light so that quasi- natural light is more nearly true nature light, but also colour rendering index is further promoted.
(4) relative spectral power of feux rouges is improved, so that spectrum is more nearly natural light, 640~700nm feux rouges has
Healthcare function, and then improve the Health Category of quasi- natural lighting.
(5) quasi- natural light is obtained using the combined form of white-light emitting body 2021 and red emitting luminophores 2022, it is simple for structure,
Variable controllability is good in debugging process, is achieved the debugging of quasi- natural light, and passes through supplement red emitting luminophores 2022
Quasi- natural light is obtained, solves the problems, such as that quasi- natural light can not be obtained in such a way that blue chip and fluorescent glue combine.
In one embodiment, the first chip 20211 is blue chip, the wave-length coverage of blue chip be 450nm~
480nm；The wave-length coverage of red light chips be 640nm~700nm, the central wavelength of red light chips be preferably 690nm ± 5nm,
680nm ± 5nm or 670nm ± 5nm.Preferably, the wave-length coverage of blue chip is 457.5nm~480nm, at least
457.5nm~460nm, to can further improve green light ratio.In numerous white LED light sources, green light ratio is difficult to
It is promoted, is more difficult to promote green light in the case where reducing blue light ratio, while colour rendering index R12 corresponding with green light is also
It is difficult to be promoted.The present embodiment breaks through orthodox practice and (generallys use 450nm~455nm blue light core in traditional white LED light source
Piece), the blue chip of 457.5nm~480nm is selected, so that the relative spectral power of green light is obviously improved；Due to blueness
The promotion of light, while colour rendering index R12 is promoted, it also helps somewhat to be able to maintain while inhibiting blue light higher
Colour temperature.Green light relative spectral power is lower than 0.3 in the white light that the light source of traditional near-nature forest light generates, and provided in this embodiment white
The relative spectral power of green light part can then be promoted to 0.4 or more (as shown in Figure 10) in the white light that light LED light source generates.
Further, the optical parameter of white light are as follows:
When the colour temperature of white light is 2500K~3000K, the relative spectral power of 480nm~500nm wave band is greater than 0.30,
The relative spectral power of 500nm~640nm wave band is greater than 0.70；
When the colour temperature of white light is 4000K~4200K, the relative spectral power of 480nm~500nm wave band is greater than 0.45,
The relative spectral power of 500nm~640nm wave band is greater than 0.65；
When the colour temperature of white light is 5500K~6000K, the relative spectral power of 480nm~500nm wave band is greater than 0.4,
The relative spectral power of 500nm~640nm wave band is greater than 0.60.
Further, the spectrum of LED light source 20 is also extremely similar with natural light in its all band, and existing near-nature forest light light
Source is then difficult to realize.The relative spectral power of orange-colored light is greater than 0.55 in the quasi- natural light that LED light source 20 generates；The phase of sodium yellow
0.50 is greater than to spectral power；The relative spectral power of green light is greater than 0.35；The relative spectral power of purple light less than 0.10,
It is close with natural light, it is ensured that user is more comfortable when in use.
Moreover, the light that LED light source 20 generates also has stringent light while each band spectrum more optimizes
Learn parameter request, such as colour temperature, color tolerance, colour rendering index Ra, colour rendering index R9, colour rendering index R12 and blue light color ratio etc..Its
In, the colour temperature of quasi- natural light includes 2500K~6500K, and color tolerance is less than 5, and blue light color ratio is less than 5.7%.Colour rendering index Ra is big
In 95, colour rendering index RR9 is greater than 90, and colour rendering index R12 is greater than 80.Further, blue in the quasi- natural light that LED light source 20 generates
Photochromic to be reduced to 5.5% hereinafter, colour rendering index Ra is increased to 97 or more than b, colour rendering index R9 reaches 95 or more, and colour developing refers to
Number R12 has reached 83.
Further, the blue light of 440nm is maximum to the injury of eyesight in blue light, and LED light source 20 provided in this embodiment exists
While blue light color ratio is reduced to 5.7% or less, also make the relative spectral power of 440nm blue light lower than 0.65.This is existing
What the low blue light electronic equipment having was difficult to realize.Although existing low blue light electronic product blue light color is relatively low, wherein right
The inhibition that human eye injures maximum 440nm blue light is not obvious, therefore is difficult to be really achieved eye-protecting function.And other in blue light
Wavelength band components are necessary visual acuity, and significantly inhibiting blue light, not only eyeshield effect is unobvious, can also be to children, child etc.
The visual acuity of crowd causes adverse effect, such as due to the excessive missing of blue light ingredient, leads to anomalous trichromatism, chromatic discrimination power decline etc.
Problem.The present embodiment by blue light color ratio be reduced to 5.7% it is below on the basis of, emphasis inhibit 440nm blue light intensity, can
Really play the role of protecting eyesight.
