Embodiment
A kind of lighting device proposed by the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Introduced from background technology we, it is known that sleep-wake cycle is most notable, most important in all body's physiological rhythms
One of the rhythm and pace of moving things.And epiphysin is referred to as sleep hormone, with the change for biological rhythm of marking.Numerous studies show illumination for
The secretion of epiphysin significantly affects, especially shortwave blue light suppression to melatonin secretion of the wavelength between 460 ~ 480nm
Effect is most strong.Therefore, should be tried one's best in order to ensure normally to sleep, during night light reduces the energy of blue wave band.Meanwhile high energy
Amount short wavelength light, especially 460 ~ 480nm blue light can stimulate SCN, more clear-headed hormone be secreted, so as to be risen in daystart
To the effect of wake-up.
It has been proved by experiments although can apply to daystart using high-energy short wavelength light and wake up, simple blue light
Irradiation can allow people to feel dazzling, and many detrimental effects can be also produced to people, blue light harm as everyone knows, therefore
We are also desirable to use white light in the illumination of daystart.So which type of white light is only it is desirable that what is obtained can be to waking up
It is helpful, in order to intuitively be analyzed, it would be desirable to which influence of the light action in human body is quantified.Herein, we
Employ LRC research institutes of the U.S. Mark S Rea that international endorsement degree is higher, more authoritative and teach researched and developed epiphysin stimulation
It is worth theoretical model（Call CS values in the following text）.The theoretical model considers eye position spectral irradiance, and blackout albumen, photopic vision, scotopia
Feel and the S cones this spectral sensitivity curves, its algorithm are as follows:
for
for
MλContaining the retinal photoreceptor cells spectrum sensitivity function regarding melanocyte, its peak value is 480nm；
V10λThe cone cell spectrum sensitivity function of the glistening light of waves and the long glistening light of waves in perception；
V’λRod cell spectrum sensitivity function；
SλPerceive the cone cell spectrum sensitivity function of short wavelength light；
PλSpectrum eye position irradiation level（W/m2/nm）
It is desirable that obtaining has the wake-up light of larger CS values in the present invention, and influence of the illumination to CS values be it is very big, therefore
We select a specific illumination in the present invention, and CS values are weighed under unified lighting standard.According to national standard GB50034-
Provided in 2013 standard for lighting design of buildings, office's 0.75m horizontal illuminations are 300lx, are converted as illumination 400lm, and have
Research shows that 1-5 times that daystart is shone using office's normal light is suitable, therefore our selected 1000lm are used as daystart photograph
Bright normal luminance, what is referred in the CS values of clear-headed light as described below is all calculated value when illumination is 1000lm.Office's day
For 4000K light fixtures when illumination is 1000lm, the CS values for calculating acquisition are about 0.551, are carried in the present invention used by often
Its CS value of the clear-headed light gone out at least should be higher than normal light by 10%, i.e., should be more than 0.6 under 1000lm, thus can be preferable
Ground suppresses melatonin secretion.Simultaneously as illumination is not merely to wake up, the illuminating effect in daystart room is also assume responsibility for,
Therefore the comfortableness of illumination, and higher colour rendering also be must assure that.
In the present invention it is desirable that it is a kind of clear-headed light to obtain illumination output, by repetition test, it has been found that tool
The illumination output for having some specific characteristics is to meet our requirement, is exactly some for meeting these features shown in Fig. 1

580 nm to 780nm are the 3rd wavelength region, and C is expressed as in figure.The shortwave blue light pair of our known wavelengths between 460 ~ 480nm
The inhibitory action of melatonin secretion is most strong, therefore the maximum spectral intensity for illuminating output for having clear-headed effect that we need should
Positioned at first wave length region, and the energy in the region will have a certain amount, therefore the spectrum work(in first wave length region
Accounting of the rate in general power should be more than 25%, should preferably be more than 30%, more preferably more than 33%, while in order to keep away
Exempt from photochromic too blue, accounting of the spectral power in general power in first wave length region should be less than 45%, should preferably be less than
40%, more preferably less than 36%.The illumination output of usual light source is the polychromatic light formed by the Colored light mixing of different wave length, and
Spectral power in region refer in a wave-length coverage in the photochromic emittance of each wavelength summation, in the present invention
We mainly consider the Energy distribution in 440 ~ 780nm regions, therefore we are by the different wave length coloured light in 440 ~ 780nm regions
Emittance summation be referred to as illuminate output general power.In addition to shortwave blue light, in order to take into account comfortable and colour rendering, I
In second wave length region and the 3rd wavelength region should also have certain Energy distribution in illumination output, in second wave length region
Interior maximum spectral intensity is the 30 ~ 50% of the maximum spectral intensity in first wave length region, and the spectral power in two wavelength regions
Accounting in general power should be more than 30%, preferably greater than 35%, less than 50%, preferably less than 40%.In the 3rd wavelength zone
Maximum spectral intensity in domain is the 15 ~ 35% of the maximum spectral intensity in first wave length region, and the spectrum work(in three wavelength regions
Accounting of the rate in general power should be more than 20%, preferably greater than 25%, less than 40%, preferably less than 33%.Certainly, we
Target is clear-headed illumination, therefore, should be ensured that the spectral power in first wave length region is big while features described above is met
In the spectral power of the 3rd wavelength region, so can just there is a higher CS value.Through actual measurement, the illumination for meeting features described above is defeated
