Being given above is the fluorescent powder type that can be selected, in this application we provide 8 specific embodiments,
9 kinds of fluorescent powders are selected in these embodiments altogether, the parameter and chemical formula of each fluorescent powder that embodiment is selected see the table below.In order to
Convenient for description, we define code name to fluorescent powder in table 1, subsequent embodiment explanation in we just with the code name come into
Row description, is no longer all described in detail the peak value and chemical formula of fluorescent powder in each example.
Table 1
For parameter is both for this kind of fluorescent powder in upper table, x, y indicate the photochromic in the CIE1931 colour space of fluorescent powder
Coordinate value, Peak indicate peak wavelength, Hw indicate half width, the above numerical value is all the reality of fluorescent powder used in the examples
Numerical value is not limitation of the invention, because in actual production due to its different peak value of fluorescence powder purity, granular size
Wavelength and half width are likely to generally be controlled between ± 5nm, answer with above data slightly deviation, this deviation
This thinks that other schemes within this range are the same as above-mentioned fluorescent powder.
Table 2 illustrates fluorescent powder type employed in 8 embodiments and each embodiment of the application and all kinds of fluorescence
The weight of powder.The wherein accounting of each additional illuminator refers respectively to the weight of multiple fluorescent powders in each additional illuminator total glimmering
Accounting in light powder weight.And total fluorescent powder accounting refers to total fluorescent powder weight, refers to include in three kinds of additional illuminators complete
Accounting of portion's fluorescent powder in the total weight of these fluorescent powders and the mixed encapsulation part 2 of base material 204.In these embodiments
Middle base material 204 is all transparent silica gel, weight 10g.
Table 2
The data that embodiment fluorescent powder weight in table 2 is all us when making the sample chip of light source module group L1 are practical to exist
In batch production, due to fluorescent powder batch different weight all can slightly difference, but its basic accounting is in a fixed area
In.The application of all kinds of fluorescent powders number primarily to the mixed transmitting light of control in specified wavelength self-energy accounting,
Because Energy distribution influence transmitting light CS value (circular of CS value is described below detailed when embodiment spectrum
Illustrate), therefore we just have a basic requirement to the Energy distribution in each section in design chips.Here we only beg for
By the spectrum in visible-range, therefore entire spectral energy described below refers in visible-range, i.e., wave-length coverage [380 ~
780nm] in spectral energy summation.The spectrum of chip emission light: the spectral energy in wave-length coverage [380 ~ 470nm] accounts for whole
The 10.0% ~ 30.0% of a spectral energy, preferably 15.0% ~ 25.0% this；Wave-length coverage (470 ~ 560nm] in spectrum energy
Amount accounts for the 25.0% ~ 45.0% of entire spectral energy, preferably 27.0% ~ 37.0%；Wave-length coverage (560 ~ 780nm] in light
Spectrum energy accounts for the 40.0% ~ 60.0% of entire spectral energy, preferably 45.0% ~ 55.0%；In previous RGB light mixing scheme
(470 ~ 520nm] section is usually trough, and energy is seldom therebetween, and we pay special attention to this section in this application, pass through
The energy in the region is promoted to promote CS value, therefore it is required that the spectral energy in the section need to account for entire spectral energy
12.0% ~ 32.0%, preferably 17.0% ~ 27.0%.
In the case that energy binned in each spectrum section determines substantially, we use fluorescent powder also as target into
Row allotment.The energy of wave-length coverage [380 ~ 470nm] is as provided by 1 blue-light LED chip of the first light-emitting component, actually entirely
The energy of portion's transmitting light is all provided by it, and original all energy should all concentrate on the section, but due to part light quilt
It is photochromic that fluorescent powder is converted to other, thus the Energy distribution after conversion retains the energy in this section in other wave-length coverages
Lower than 30%.And wave-length coverage (470 ~ 560nm] interior spectral energy mainly shines by the first additional illuminator 201 and second are additional
It is provided after the part emergent light of the first light-emitting component 1 of conversion of body 202.Here it says mainly, this is because spectrum is continuously first
Emergent light of light-emitting component 1 itself is also not absolutely not energy in the section, is only lesser with respect to the energy after conversion.
In design chips, we are main or consider from the part that fluorescent powder is converted, and select more appropriate powder weight accounting, then practical
The bin energies are measured, the energy measured necessarily includes the energy that each illuminator provides, but is played a major role in the section
Or the first additional illuminator 201 and the second additional illuminator 202.As seen from Table 2 as the first additional illuminator 201
Blue-green fluorescent powder is in the accounting in total fluorescent powder weight in 21.7% to 32.5% this section, it is contemplated that can also use it
His type fluorescent powder, think in the application accounting of the first additional illuminator 201 in total fluorescent powder weight should 18% ~
50% within the scope of this.And the application add the second additional illuminator 202 primarily to promoted (470 ~ 520nm] section energy
Amount, but the energy of the section can not be excessively high, and it is photochromic otherwise to will affect white light, additional shines as second as seen from Table 2
The fluorescent powder of body 202 is essentially yellow, green emitting phosphor combination, the accounting in total fluorescent powder weight 36.9% to 45.8% this
Think in one section, in the application accounting of the second additional illuminator 202 in total fluorescent powder weight should 22.0 ~
52.0% within the scope of this.Wave-length coverage (560 ~ 780nm] spectral energy mainly by adding the red of illuminator 203 as third
Color or orange fluorescent powder provide, and third adds accounting of the illuminator 203 in total fluorescent powder weight 27.4% to 34.5% in table 2
In this section, 8% ~ 38% can be expanded within the scope of this by being further considered as other fluorescent powder accountings other than embodiment.
These fluorescent powders can be coated on LED chip by being mixed into transparent silica gel, be also possible to long-distance fluorescent powder and be arranged in distance
Chip remote position, or part are mixed into packaging plastic, and part is arranged in outer surface, and the application is not construed as limiting this.

Table 3
The characteristics of luminescence of light source module group L1 in embodiment 1-8 is listed in table 3, wherein x, y indicate the transmitting light of light source module group L1
The photochromic x in CIE1931 coordinate, the coordinate value in y-axis, CCT is colour temperature, and duv indicates the color in coordinate
The distance and direction, CRI for deviating Planckian locus are colour rendering index.CS value 500lux indicates that light source module group L1 is sent out in this application
CS value of the light in illumination 500lux is penetrated, specific formula for calculation is as follows:
Wherein
, if；
, if
Wherein
P0(λ): light source light spectrum distribution

It may be seen that CS value of the transmitting light of the light source module group L1 of all embodiments in illumination 500lux from table 3
It is all larger than 0.42, and its colour rendering index meets CRI >=90.0.And we are by photochromic be labeled in that shine in each embodiment
In CIE1931 coordinate, as shown in figure 3, the photochromic black body locus for all falling within 5000 ± 350K of correlated colour temperature of each embodiment
Near, it is respectively less than 0.006 away from black body locus BBL distance, i.e. duv is in -0.006 ~ 0.006 this section.And all the points are fallen
Be located at by point D1 (0.3364,0.3564), D2 (0.3356,0.3323), D3 (0.3537,0.3465), D4 (0.3578,
0.3739) in the quadrilateral area that four vertex surround, i.e. depicted area 1.User's experiment is carried out to these embodiments in the later period
Afterwards, it has been found that the effect of embodiment 1,3,4,5,6 is more preferable, and we are it can be found that these points both fall within diagram area from Fig. 3
In domain 2, point x0=0.3541 centered on region 2, y0=0.3516, long axis a=0.00274, short axle b=0.00118, inclination angle theta=
59.4 °, the ellipse of SDCM=5.0.
Why can be realized higher CS value in these embodiments that we provide, mainly since transmitting light is in difference
The Energy distribution of wavelength, these features are other than the different wavelength regions energy distribution defined before us is different, more
It is specifically embodied on the wave character of spectrum.Fig. 2 is the spectrum characteristic for best embodying the application light source module group L1 transmitting light
Schematic spectrogram, we are illustrated the spectrum characteristic of the application according to Fig. 2.It can be seen in fig. 2 that emissioning light spectrum packet
Include the first peak P1 being sequentially distributed, the first peak valley V1, the second peak P2, the second peak valley V2, the second peak P3.
First peak P1 is located in 435 ~ 465nm wavelength region, since light source module group L1 is by 1 blue light of the first light-emitting component
LED chip as excitation light source, although the light that blue-light LED chip issues have greatly transmitting light by additional illuminator into
Go wavelength convert, but still some energy is unconverted, these energy form in 435 ~ 465nm wavelength region
One peak, this P1 point may be identical with the peak wavelength of blue-light LED chip, because the main source of the energy at this peak is first
Light-emitting component 1, but the light after each additional illuminator conversion may also have portion of energy in the wavelength period, after the two mixing,
This first peak P1 might not be completely coincident with the peak wavelength position of 1 blue-light LED chip of former first light-emitting component, may be slightly
There is drift, but still in 435 ~ 465nm wavelength region.First peak P1 is interior generally within [380 ~ 470nm], so wavelength exists
Energy in [380 ~ 470nm] section is mainly exactly the energy of first peak P1.
Second peak P2 is located in 485 ~ 525nm wavelength region, and the energy of the second peak P2 is by the first additional illuminator 201
Blue-green fluorescent powder receives the blue green light that some light that 1 blue-light LED chip of the first light-emitting component is emitted is converted into and is mentioned
It supplies.The ratio of the spectral intensity of the spectral intensity and first peak P1 of second peak P2 between 50% ~ 90%, preferably 60 ~
80%。
Third peak P3 is located in 595 ~ 645nm wavelength region, and the energy of third peak P3 is that illuminator 203 is added by third
Red or orange fluorescent powder receives the feux rouges institute that some light that 1 blue-light LED chip of the first light-emitting component is emitted is converted into
It provides.The ratio of the spectral intensity of the spectral intensity and first peak P1 of third peak P3 between 50% ~ 80%, preferably 45 ~
60%.Wavelength of transmitted light range (560 ~ 780nm] in spectral energy mainly by third peak P3 provide.
First peak valley V1 is the spectrum minimum point between first peak P1 and the second peak P2, and the energy in two peak bases portion exists
This superposition, therefore the ratio of the spectral intensity of the spectral intensity and first peak P1 of the first peak valley V1 can be more than or equal to 25.0%.
Second peak valley V2 is the spectrum minimum point between the second peak P2 and third peak P3, due to the second peak P2 and third
Peak P3 distance farther out, only rely on the second peak P2 energy not can guarantee transmitting light wave-length coverage (470 ~ 560nm] in spectrum
Energy keeps 25.0% ~ 45.0% accounting in entire spectral energy.Therefore the second additional illuminator is increased in the application
202, receive the energy that the green-yellow light that some light that 1 blue-light LED chip of the first light-emitting component is emitted is converted into provides
Be distributed in (470 ~ 520nm] in region, this Energy distribution has raised the second peak valley V2 simultaneously, so that the spectrum of the second peak valley V2
The ratio of intensity and the spectral intensity of first peak P1 is between 50.0% ~ 70.0%, and preferably 40.0% ~ 60.0%.Here we
Again illustratively, the second additional illuminator selects a kind of yellow or green emitting phosphor it is also ensured that at this for ordinary circumstance
Energy accounting, still, such spectrum big rise and fall may re-form a peak between the second peak P2 and third peak P3, when
So the appearance at new peak will not influence the CS value of entire spectrum, and the second peak valley V2 is also still positioned at the second peak P2 and third peak P3
Between spectrum minimum point.But consider that the Energy distribution that we are also desirable to the section is more uniform from colour rendering angle, because
This second additional illuminator 202 in preferred embodiment 1-8 all uses the different two kinds of fluorescent powders mixing of peak wavelength, and this
Two kinds of fluorescent powders are preferably, and select the fluorescent powder of different colours, i.e., a kind of is yellow fluorescent powder, and another kind is green fluorescence
Powder.After the mixing of two kinds of fluorescent powders, the part of the first light-emitting component 1 of conversion provided after shining wave-length coverage (470 ~ 520nm] section
Interior main energetic.And wave-length coverage (470 ~ 570nm] section energy, then added by the first additional illuminator 201 and second
Illuminator 202 provides jointly.
Above crest location can guarantee our the energy accountings in each section substantially, but further limit second
Peak energy ratio between peak P2 and third peak P3, can obtain better illumination effect, be further ensured that obtaining for high CS value
, and ensure high photosynthetic efficiency and high-color rendering.In the preferred embodiment, the light of the spectral intensity of third peak P3 and the second peak P2
The ratio of spectral intensity is between 75% ~ 115%, and preferably 80% ~ 110%.
In Fig. 2 it may be seen that emissioning light spectrum be it is continuously distributed, it is so-called continuously distributed to refer to the curve of spectrum
It is more gentle, there is no biggish energy fluctuation occurs between adjacent two o'clock, as shown in the spectrogram 4-11 of each embodiment, several
Not having spectral energy between a wave crest is 0 point, and such curve of spectrum can guarantee that the every bit in 380 ~ 780nm has
Certain Energy distribution, so that the spectrum has preferable colour rendering.
Table 4 lists the characteristic value of each spectrum of embodiment 1-8, and P1, P2, P3, V1, V2 respectively refer to first peak P1, in table
