Statement " visibly different color (visibly distinct color) " word means there is twenty-twenty vision People is able to detect that the color difference between light (for example, the light that projects from first light engine and projecting from second light engine Light between color difference).

Statement " light for projecting light engine has first color dot " (and similar or similar statement) refers to injection light engine The color dot that has of light (or mixed light), i.e., if the light for projecting the light engine be entirely single color dot light (for example, if Light engine only includes a light source), the light for projecting light engine has the color dot, and if the light for projecting light engine is not homochromy The mixed light (for example, if light engine includes the light source of the light of the different color dots of two or more transmittings) of point, projects light engine Light have mixed light color dot.

Unless otherwise defined, belonging to the meaning and the present invention used herein of all terms (including scientific and technical terms) The meaning that the those of ordinary skill in field is commonly understood by is identical.It should further understand that as defined in conventional use of dictionary It is consistent with their meanings in related fields and context environmental of the invention that those terms shall be interpreted as its meaning, removes Non- explicitly define herein will not understand from the level of ideal or over-formalization (formal sense) outside.The technology of this field Personnel should also be understood that structure or feature referring to " neighbouring (adjacent) " another feature distribution can have the feature neighbouring with this Overlapping or part under it.

The color of the visible light of light source transmitting and/or the mixing visible light of multiple light sources transmitting can be in 1931CIE (Commission International de I'Eclairage, International Commission on Illumination) chromatic diagram or 1976CIE chromatic diagram Upper expression.Those skilled in the art are familiar with these figures, and these figures be all be readily available (for example, can by because Special internet retrieval CIE chromaticity diagram obtains).

CIE chromaticity diagram is with two CIE parameter x and y (in the example of 1931 figures) or u^’And v ' is (in the example of 1976 figures In) form delineate human color perception.The corresponding specific tone of each point (i.e. color dot) on each chromatic diagram.Example Such as, for the technical description of CIE chromaticity diagram, reference can be made to " physics and technology encyclopedia " volume 7,230-231, Robert etc. It writes, 1987 (" Encyclopedia of Physical Science and Technology ", vol.7,230-231, Robert A Meyers ed.,1987).Spectrum colour is distributed in the perimeter of profile space comprising all human eyes can perceive All colours.The maximum saturation of boundary line expression spectrum colour.

1931CIE chromatic diagram can be used to for color being defined as the weighted sum of different tones.1976CIE chromatic diagram with 1931CIE chromatic diagram is similar, and difference is in 1976 chromatic diagrams that similar distance indicates similar perception color difference.

" tone " word as used herein means with the color difference (color for corresponding to specified point on CIE chromaticity diagram Shade) and the light of saturation degree, it can using the x and y coordinates on 1931CIE chromatic diagram or the u ' on 1976CIE chromatic diagram And v ' is come the point that characterizes.

In 1931 figures, coordinate can be used to indicate from the offset for scheming a upper point, or for the color difference to perception Degree provides instruction, and MacAdam's ellipse (MacAdam ellipses) can be used to indicate from the offset for scheming a upper point.Example Such as, the particular shade of color (hue) defined with the specific set of coordinates on 1931 figures is defined as at a distance of 10 MacAdam's ellipses The track in multiple sites, multiple tones by being perceived as differing same degree with the particular shade of color form (and for being defined as With particular shade of color at a distance of the site track of the MacAdam's ellipse of other quantity, and so).

Typical human eye can distinguish the tone being spaced each other more than 7 MacAdam's ellipses, and cannot differentiate to each other Every 7 or the tone of less MacAdam's ellipse.

Since the similarity distance on 1976 figures indicates similar perception color difference, the offset of any can be with coordinate from 1976 figures The form of u ' and v ' indicates, for example, to distance=(Δ u ' of the point²+Δv’²)^1/2, and by with particular shade of color at a distance of phase The tone that the track definition of the point of same distance goes out, by having multiple tone groups of same degree perception difference with the particular shade of color respectively At.

Chromaticity coordinate (it is, color dot) along black body locus follows Planck (Planck) formula E (λ)=A λ^-5/(e^{(B /T)}- 1), wherein E is emissive porwer, and λ is launch wavelength, and T is the colour temperature of black matrix, and A and B are constants.On black body locus Or neighbouring chromaticity coordinate issues the white light for being suitble to human viewer.1976CIE figure includes the temperature list along black body locus. The temperature list shows the color locus for the blackbody radiation source for causing the temperature to rise.When heated object begins to send out visible light When, feux rouges is issued first, followed by yellow light is finally blue light followed by white light.Can this thing happens be because and black matrix The relevant wavelength of the radiation peak of radiation source can shorten as the temperature rises, this meets Wien shifting theorem (Wien Displacement Law).In this way, it is capable of emitting positioned at light on or near black body locus to describe that the form of colour temperature can be used Illuminator.

Statement " dominant wavelength " used herein according to it is known that and widely accepted definition refer to that spectrum can be by The color of perception, that is, the generation of light are most similar to that color sense of color perception perceived when the light that observation light source issues The single wavelength (it is, it is approximately similar to tone) felt.As for " peak wavelength ", known to refer to spectrum function in light source Spectral line with maximum power in rate distribution.Because human eye cannot equably perceive all wavelength, (perception yellow and green are excellent In red and blue), and since light of multiple solid-state light emitters (such as LED) sending is actually in a wave-length coverage, Therefore the color (namely dominant wavelength) of perception is it is not necessary to be equal to the wave that (and being usually different) has peak power Long (peak wavelength).Really monochromatic light such as laser dominant wavelength having the same and peak wavelength.

Statement " peak strength angle (peak intensity angle) " used herein is according to it is known that and wide The definition of general receiving refer to the light of the maximal illumination emitted from light source (or multiple light sources) relative to plane propagation at an angle, I.e. for the plane of definition for each angle (for example, integer angle, 0 degree, 1 degree, 2 degree ... 89 degree and 90 degree) relatively described Plane is determining at the illumination (illumination) of the light of the angular spread, and just for the determining angle of maximal illumination It is peak strength angle.

The statement of " light of the first light engine output provides the first CS value " (or similar) means in any other no light In the case where, the light of the first light engine output will provide the first CS value.That is, such statement is not offered as the first light and draws The light for holding up output is not mixed with other light from other one or more light engines, or the illumination comprising the first light engine Total light outputs of lamps and lanterns provides such first CS value, such as the light of output of illuminator may include at least from the second light The light output of engine, and the mixing light output of the light output of the light and the second light engine of the first light engine output can have not It is same as polymerization (aggregate) CS value of the first CS value.

It is well known that the light source for emitting the light of different tones (two or more) can be combined to generate tool There is the mixed light (for example, non-white light corresponding with required color dot or white light with required colour temperature etc.) of required tone.Many institute's weeks Know, the color dot that color mixing generates easily can be predicted and/or be set by the simple geometry figure on CIE chromaticity diagram Meter.It is well known that from the concept of desired mixed light color dot, (notion), those skilled in the art can easily be selected The light source for selecting different tones, when being mixed, these light sources will provide desired mixed light color dot.For example, art technology Personnel can choose the first light engine (e.g., including light emitting diode and phosphor (phosphor)), in CIE chromaticity diagram subscript The color dot (i.e. first color dot) for drawing the light projected from the first light engine marks and draws expectation color dot range (or the single expectation of mixed light Color dot), and the expectation color dot range (or individually it is expected color dot) that one or more line segments extend through the mixed light is drawn, this These line segments of sample extend to except desired color dot.The every line segment drawn in this way will have endpoint in the first color dot, and By by the expectation color dot range (or individually it is expected color dot) of the mixed light, and there will be another endpoint in the second color dot.It can Second light engine is provided, wherein projecting the light with the second color dot, and makes it when being powered to the first light engine and the second light engine When shining, mixed light color dot be must be positioned on the line segment for connecting the first color dot and the second color dot, and the mixed light is along described The position of line segment will depend on the opposite of the light that (dictate) (i.e. proportional) is projected respectively from first and second light engine Brightness.That is, the ratio of the light from the second light engine in mixed light is bigger, the mixed light color dot is about close to the second color Point, this relationship are being geometrically proportional, the i.e. length of the line segment at the interval of mixed light color dot and the first color dot Score is equal to the light from the second light engine and accounts for the score (vice versa) of the mixed light, or is indicated with geometric terminology are as follows: (1) From first color dot to the distance of the mixed light color dot divided by (2) from first color dot to the ratio of the distance of the second color dot (ratio) by the brightness (lumen) equal to the first light engine divided by the ratio of the combination brightness (lumen) of mixed light.Therefore, once It has been determined that offer extends through the light source (or light engine) of the endpoint of the line segment of desired mixed light color dot, can have been arrived by calculating Relative luminance up to desired first and second light source (or light engine) of the color dot of the desired mixed light is obtained with The color dot of the desired mixed light.

When using more than two light source (and/or light engines) (for example, the light of the first color dot from first light source, The mixing of the light of light from the second color dot of second light source and the third color dot from third light source), which can be used for really It protects and obtains desired mixed light color dot.For example, it is conceptive, it can determine from first light source (or first light source engine) and second The sub- mixed light color dot of the sub- mixed light of light source (or second light source engine) then determines the sub- mixed light (the sub- mixing The brightness of light is the first light source (or first light source engine) and the combination of the second light source (or second light source engine) is bright Degree) and third light source (or third light source engine) mixed light mixed light color dot.It may then pass through from drafting and connect these The circumference (perimeter) that the line segment of each color dot of light source (light engine) obtains defines the range of mixed light color dot.

One or more scatterers can be added in any embodiment shown in Figure 21-22 (or it is according to the present invention In any other embodiments in the third group embodiment of the first aspect of purport), such as scatterer 138 in Figure 13 to be added To the mode in embodiment shown in Fig. 7, or with any relevant way described in any Figure 13.

In some embodiments of purport according to the present invention, including some embodiments, in these embodiments include or not Including some features described herein, the far-field distribution of the light projected from the first light engine be different from from the second light engine and/or The far-field distribution of the light projected from side wall (including any first light engine, the second light engine and/or side wall described herein).

In the one side of each far-field distribution of light, the distribution of the light projected from the first light engine is compared from the second light engine The distribution of the light of injection goes out the plane of area definition closer to the light emission for being vertically to the space defined by side wall.Such as in Fig. 7,11- In each embodiment shown in 15, the distribution for the light that the distribution ratio of the light projected from the first light engine is projected from the second light engine is more Close to vertically.

The light projected from the first light engine is than from the light that the second light engine projects closer to the representative example of specific direction Son includes:

[1] the 60% of the light projected from the first light engine the opposite direction defines the angle 0 degree to 45 degree, and from The opposite direction of the 40% of the light that first light engine projects defines the angle between 45 degree to 90 degree, and

The 30% opposite direction of the light projected from the second light engine defines the angle 0 degree to 45 degree, and from the The opposite direction of the 70% of the light that two light engines project defines the angle between 45 degree to 90 degree, and；Or

[2] the 30% of the light projected from the first light engine the opposite direction defines the angle 0 degree to 25 degree, and from The opposite direction of the 65% of the light that first light engine projects defines the angle between 25 degree to 90 degree, and

The 20% opposite direction of the light projected from the second light engine defines the angle 0 degree to 25 degree, and from the The opposite direction of the 80% of the light that two light engines project defines the angle between 25 degree to 90 degree.

In some embodiments, the distribution of the light projected from the second light engine is about being vertically to (relative to Perpendicular to) light emission goes out the angle in area and is greater than the distribution of light projected from first light engine, and this is helped to create The illusion that relatively bright sunlight is reflected, and sky is visible but is not so bright.

In the another aspect of each far-field distribution of light, the distribution of the light projected from the first light engine is compared to be projected from side wall The distribution of light go out area definition closer to the light emission for being vertically to the space that (closer to perpendicular) is defined by side wall Plane.Such as in each embodiment shown in Figure 16, what the distribution ratio of the light projected from the first light engine was projected from side wall The distribution of light is closer to vertically (closer to vertical).

In discussed above, the distribution of light goes out the plane of area definition about the light emission being vertically in the space defined by side wall It is described.In some embodiments, the distribution of light will be described as defining about the maximum periphery being vertically to by illuminator Plane, or go out about rotation axes of symmetry, or about the intersection point of two symmetrical planes, or about the light emission for being vertically to the first light engine The plane that face defines, or about being vertically to the plane tangent with the light emergence face of the bending of the first light engine or cheese, or close In the plane that the surface (such as smallpox, wall, floor, incline structure etc.) for installing the illuminator defines.

In the another aspect of each far-field distribution of light, the distribution of the light projected from the first light engine, which is compared from the second light, draws It holds up the distribution of the light of injection and is determined by the light emergence face of the first light engine closer to being vertically to (closer to perpendicular) The plane (or plane tangent with the light emergence face of the bending of the first light engine or cheese) of justice.Such as shown in Figure 21-23 Each embodiment in, the distribution of the light projected from the first light engine is than the distribution of light projected from the second light engine closer to erecting Directly (closer to vertical).

In the illuminator of some embodiments in the third group embodiment of the first aspect of purport according to the present invention:

The light projected from the first light engine has the first peak value intensity relative to the first plane, and first plane is by institute State 1 points of definition on the first light emergence face；

The light projected from the second light engine has the second peak strength angle relative to first plane；And

The first peak value intensity is different from second peak strength angle.

In the illuminator of purport according to the present invention and/or some embodiments of method, including some embodiments, In include or do not include any feature described herein, among the light for projecting the illuminator, at least there are some light The color dot of the variation of color (light color), the light propagated with first angle relative to light distribution axis is different from relative to light The color dot for the light that distribution axis is propagated with second angle.These differences on color dot are relatively small or larger, such as in 10 steps (step) MacAdam's ellipse (10-step), 20 step MacAdam's ellipses, at least 0.05 unit on 1931CIE chromatic diagram, extremely Few 0.10 (or 0.15,0.20.0.25.0.30.0.35,0.40,0.45 or 0.50) unit.

In some such embodiments (that is, the color of the light projected from illuminator at least has the reality of some variations Apply in example), at least part of the color point variation is due to from the first light engine (being similar to sky) and from the second light Caused by the different far-field distribution contributions of engine (being similar to the sun).Including wherein the first and second light engine in this specification Far field light distribution property illuminator and method different from each other a variety of associated descriptions.

For traditional light, the color change in angle (is propagated in different angle relative to light distribution axis Light color dot be markedly different from relative to light distribution axis in the illumination of the color dot for the light that second angle is propagated) be not usually Ideal characteristic.However, color change is an important element of nature skylight, therefore for creating or enhancing artificial skylight Illusion is desirable.Due to the basic geometry (the recessed box i.e. in the smallpox of band center window) of (1) typical skylight, (2) too Positive only visible under special angle (depending on the time in one day), (3) sky is visible in relatively large angular range； The light for entering space from skylight conduction usually has (i.e. blue and white) region high CCT and the low region CCT (i.e. yellow-white) region.This Invention some embodiments provide this feature.

Figure 24 A, which is shown, uses the illuminator and its detector similar with the embodiment of illuminator shown in Figure 16 (detector) has about 6.5 feet of angle spectrophotometer device (gonio- with the illuminator distance Spectrophotometer arrangement) measurement CCT and visual angle relational graph.When angle is zero degree (if illumination Lamps and lanterns are taken in day, then correspond to the underface of illuminator), CCT is about 6500K.When visual angle is 75 degree, CCT is down to 4700K or so.In broad terms, the light from natural skylight when this feature is lower on high similar to the sun.These CCT values Representative-of the invention purport is not limited to these CCT values and range with range, those skilled in the art will recognize that Purport of the invention may include other CCT ranges, and is contemplated that and uses various CCT ranges.

Another feature of natural light is that it usually provides the light of high quality, and colour rendering index (CRI) is about 100.This is Because daylight is usually full spectrum light (definition for also reflecting CRI).In addition, all keeping very high CRI regardless of CCT.Cause This, a desired characteristics of artificial skylight are that it provides the light with high CRI.

Figure 24 B shows the relational graph using setting measurement CRI and visual angle as described above.Regardless of CCT, conduction Light all has high CRI (about 85) under all visual angles.Therefore, the light perceived in the space being illuminated is of high quality, Which increase the illusion of skylight.In some embodiments of purport according to the present invention, the CRI of the light of illuminator conduction is in institute Being at least 80 on angled, (and in some embodiments, 85) CRI of the light of illuminator conduction is at least.Also it can be used The replacement color quality index (such as those described in TM30-15) of CRI.

The method familiar to those skilled in the art for realizing high CRI value, selects suitable component (such as LED component) to realize height CRI value is very simple, therefore undebatable a variety of methods for realizing high CRI value.

In animal body, the cyclical level of melatonin (melatonin) is usually in daily circulation Variation.Melatonin signal is formd to be caused drowsiness and reduces body temperature and come adjust sleep-wake cycle be by chemical method A part of system.

Lux is a kind of measurement method of intensity of illumination that human eye can identify.This value and radiation or reflected energy Objective value is uncorrelated, because human eye is different to the perceptual sensitivity of the different wave length in visible spectrum.The quantization of lux is logical Assessment luminous intensity is crossed to consider this variable.

The apparent sensitivity of human circadian's system is different from the luminosity function (luminosity for measuring lux function)。

While not wishing to be bound by any theory, but some theories think, human body melatonin is generated by tested The influence of the wavelength for the light that person is exposed to the open air.One typical example of this correlation may be:

The opposite melatonin that the light of wavelength about 410nm provides about 0.35 to human body inhibits (elative melatonin suppression)；

The opposite melatonin that the light of wavelength about 425nm provides about 0.7 to human body inhibits；

The opposite melatonin that light of the wave-length coverage in 437 to 462nm provides about 0.95 to human body inhibits；

The opposite melatonin that the light of wavelength about 475nm provides about 0.8 to human body inhibits；

The opposite melatonin that the light of wavelength about 500nm provides about 0.4 in the mankind inhibits；And

The opposite melatonin that the light that wavelength is about 600nm provides about 0 to human body inhibits.

Inhibit can be with the example of the relational graph of the optical wavelength of subject's exposure for the melatonin that human body generates opposite Found in the article that Rea et al. is delivered on " circadian rhythm magazine " (see Fig. 3) (2010,8:2 (http: // www.jcircadiorhythods.com/content/8/1/2)。

The CS value (" values (circadian stimulus value) round the clock ") of light source, which refers to work as, is exposed to light source (i.e. The illumination that eyes receive) when, the measured value for the percentage that epiphysin inhibits, i.e., 0.2 CS value indicates 20% epiphysin suppression System, 0.4 CS value indicate that 40% epiphysin inhibits, and 0.6 CS value indicates that 60% epiphysin inhibits, and 0.8 CS value indicates 80% epiphysin inhibition etc..The description of CS value, Rea et al. 2012 " human circadian's system spectrum is sensitive It is described in degree modeling "；See also connection network address www.lrc.rpi.edu/programs/lighthealth/ on line index.asp。

Circadian rhythm disorder and nocturnalism variation (such as night shift), longitude variation (such as time difference) and/or light application time Seasonal variety (such as seasonal Emotional Disorders, symptom include depression) it is related.2007, the World Health Organization was by night work It is classified as the factor being potentially carcinogenic.
