Description
Technical field
The invention belongs to electronic information field, specially semiconductor photoelectric device, green illumination and presentation of information, especially relate to
And it is a kind of in visible-range have transmitting sunshine spectrum configuration white light LED part method for packing and utilize this device
The healthy light source of making.
Background technology
The forth generation green semiconductor that white light LEDs are referred to as after incandescent lamp, fluorescent lamp and high-voltage gas discharging light shines
Mingguang City source, there is operating voltage low (2.6-3.2V), efficiency height, energy consumption low heat-emissive few (reduction greenhouse effects), friendly to environment
Kind (no mercury pollution), and small volume, shatter-proof work advantage.Thus, LED has just obtained quick popularization and application once appearance, wherein
Reach 100% in display backlight source domain permeability.Although semiconductor lighting has the remarkable advantage of energy-saving and environmental protection,
But LED green illumination healthy functions how are assigned, it is still a major challenge.
In early days, white light LEDs mainly coordinate yttrium-aluminium-garnet (Y using GaInN blue-light LED chips3Al5O12:Ce) yellow is glimmering
The encapsulation of light powder forms, but not only colour temperature is high for this white light LEDs, and colour rendering index is low.Then, propose to use three-primary colours scheme,
The fluorescent material of feux rouges can mainly be launched in right amount by being added on the basis of above-mentioned blue+yellow binary color, or using LED chip
Launch blue light and coordinate green and the three primary colours scheme of red fluorescence powder.But no matter binary color or three-primary colours white light, in its spectrum
Blue light ingredient ratio is high, otherwise can not allot corresponding white light.Blue light ingredient height can produce " rich oil blackeite " harm.Blue light is black to taking off
Inhibitory action is known as, causes nervous excitation, causes sleep disordered, influences to take charge of the occasion rhythm and pace of moving things and a series of functional disturbances, so as to drop
Low immunity.Department occasion arrhythmia generally require the long period just it is observed that.
With the popularization of LED illumination light source, a phenomenon for being easier to observe is that A nearsighted person sharply increases.One side
Face, smart mobile phone, which develops, make it that the functions such as mobile phone communication, video, reading, payment, shopping are stronger and stronger, for largely " bowing
Race " user, worked for a long time using mobile phone or for a long time under LED illumination light source, feel that visual impairment is obvious；On the other hand
Hospital ophthalmology eyesight outpatient service, teenager and child A nearsighted person dramatically increase, and myopia degree is deepened and A nearsighted person is to low
Age, direction developed.
Harm of the blue light to human eye mainly has two aspect mechanism.Firstth, blue photons energy is high, and it is straight can to penetrate crystalline lens
Up to retina, causing retinal pigment epithelium atrophy, cause ARM, photaesthesia Apoptosis causes visual impairment,
Even blind.；Crystalline lens absorbs some blue light muddy formation cataract gradually.Children's crystalline lens is limpid, can not effectively keep out indigo plant
Light, it is easier to cause ARM and cataract.Second, because blue light wavelength is short, its focus it is forward in retina and
It is not on retina.Want to see, tensile stress state of the eyeball necessarily at tension.Work, cause under blue light for a long time
Visual fatigue, cause myopia development, diplopia even occur, easily serial during reading, notice can not be concentrated, and cause study and work
Efficiency declines.
In recent years, in order to reduce blue light harm, industry proposes full-spectrum LED encapsulation scheme.The LED that full-spectrum LED refers to
Launch wavelength scope can cover all visible regions, and have a small amount of ultraviolet light and infrared light, and spectrum is continuous, without ratio
The crest extremely lacked of proper care and trough [Li Qi, Xin Yi, Chinese electric lighting, 2017,3,12].UV-shares in full spectrum have
Help environment sterilization, and infrared ray contributes to crop growth.However, we pass through the spectral component point to the sun in natural light
Analysis shows that it is 480-560nm spectral components that content is relatively large number of in sunshine, and lacks ratio in LED illumination light source at present
More spectral component is that trough is the cyan light that 490nm wave-length coverages are 480-530nm.In addition, because UV photons energy
Amount is higher, and ultraviolet injures bigger (typical example, highlands blind person's ratio are higher than plains region) to human eye；And infrared ray because
It is not responding to for human eye visibility function, infrared do not work not only in lighting source adds energy consumption and greenhouse effects on the contrary.Again
Person, contain certain ultraviolet spectrogram composition originally in solar spectrum, it is not necessary that UV-shares are added in lighting source.
Sterilized if necessary to environment, extraordinary bactericidal lamp can be opened in the case of non-illumination, illumination is separately carried out with sterilizing lamp.
Generally different colours are designed as in Art Design one 360 ° of two dimensional surface palette, and to solar spectrum
Analysis shows are carried out, sun light intensity is an asymmetrical spectrum configuration with Wavelength distribution.Crystals in Symmetry law (law of
Crystal symmetry) show can not possibly there is five secondary axes and the symmetry axis higher than six times in crystal.Therefore, we recognize
It is to use five yuan of colors to encapsulate the preferred plan of the white light LEDs of solar spectrum configuration.Although using quaternary color scheme also can convergence too
Sun spectrum, but comparatively speaking be easier to encapsulate out the white light LED part with asymmetric solar spectrum configuration using five yuan of colors.This
Invention is based on to visible spectrum constituent analysis in human eye vision respective function and solar spectrum, and proposition prevents ultraviolet and infrared, drop
The strategy of low indigo color spectrum composition, using quaternary color or five yuan of color technical schemes, arranged in pairs or groups cyan, green using blue-light LED chip
Color, red or orange fluorescent powder, or utilize UV LED chip collocation blueness, cyan, green, red or orange fluorescent powder, envelope
Take on the white light LEDs health light source with solar spectrum configuration.
