Hereinafter, briefly explaining the optimization process for being directed to identical driving current in the LED light source 111.
Include the following steps for the optimization process of identical driving current:
Step S10:White-light emitting body is chosen, white-light emitting body is for issuing white light;
Step S20:The spatial distribution for optimizing white-light emitting body, is optimized for the first near-nature forest light for white light;
Step S30:According to the spatial distribution of the first near-nature forest light and the spatial distribution of natural light, the first near-nature forest is determined The wave band to be optimized of light;
Step S40:According to waveband selection red emitting luminophores to be optimized;
Step S50:Determine the initial luminous flux ratio of white-light emitting body and red emitting luminophores;
Step S60:By adjusting the spatial distribution of white-light emitting body and red emitting luminophores, optimize white-light emitting body and feux rouges The combination spectrum of illuminator obtains near-nature forest light and identical with the driving current of red emitting luminophores or both the difference of white-light emitting body Within a predetermined range;Wherein, the adjusting of the spatial distribution of white light illuminator and red emitting luminophores is included at least to driving current Adjusting.
In the optimization process, first using the white-light emitting body as host emitter, wavelength model that host emitter is included Enclose it is larger, include at least 400nm~640nm wave band.White light is optimized for the first near-nature forest light, so that the white light connects as far as possible Near-nature forest light improves the relative spectral power of white light as far as possible in optimization process, in this way, subsequent red emitting luminophores Type selection is more simple, and is conducive to the optimization to two illuminator combination spectrums, what the white-light emitting body after optimization generated First near-nature forest light has previously described feature.
With reference to the first near-nature forest light spectrum, it can determine and require supplementation with 640nm~700nm feux rouges.And then it selects rubescent The red emitting luminophores of light, one side is used for and the combination of white-light emitting body, obtains the illuminating ray for being more nearly natural light;It is another Aspect, by supplementing feux rouges, it is possible to reduce blue light color ratio, to reduce the ratio of blue light.
Further, according to the curve of spectrum of the first near-nature forest light, and by a large amount of combination spectrum pilot scale studies, determining should The central wavelength selection of red emitting luminophores is preferably 690nm ± 5nm, it is therefore intended that and can after the combination of the first near-nature forest light spectrum Make the relative spectral power of 640nm~700nm feux rouges close to the spectrum of natural light as far as possible.
After determining white-light emitting body and red emitting luminophores, reasonable light can be selected logical according to the spectrum of two illuminators Ratio, i.e. the ratio between the luminous flux of white-light emitting body and the light radiation of red emitting luminophores, referred to herein as " initial luminous flux ratio " are measured, According to the wave-length coverage and spectral signature of above-mentioned first near-nature forest light and feux rouges, it can primarily determine that the initial luminous flux ratio exists 2~10:It is feasible in the range of 1.Further, it may further determine that the initial luminous flux ratio 2~5 by experiment:1 In the range of, then according to preset initial luminous flux than lighting the white-light emitting body of respective numbers and the feux rouges hair of respective numbers Body of light optimizes the process of combination spectrum.
Further, step S60 includes:
S601:The driving current of white-light emitting body and red emitting luminophores is adjusted, and monitors combination spectrum in real time, when a group light combination When the relative spectral power of spectrum reaches preset range, step S602 is carried out, step S601 is otherwise repeated;
S602:The optical parameter of detection combination spectrum carries out step S603 when optical parameter reaches preset range, no Then come back for step S601;
S603:The driving current for adjusting white-light emitting body and/or red emitting luminophores, makes two driving currents reach unanimity;
S604:According to the variation of the relative spectral power of combination spectrum, the luminous flux and/or feux rouges of white-light emitting body are adjusted The light radiation of illuminator, and monitor combination spectrum in real time, when the relative spectral power of combination spectrum meets preset range, into Otherwise row step S605 carries out step S601;
S605:The optical parameter of detection combination spectrum, when optical parameter reaches preset range, confirmation obtains near-nature forest Light carries out step S606, otherwise carries out step S601;
S606:Record the practical driving current of white-light emitting body and red emitting luminophores, the luminous flux of white-light emitting body and red The actual ratio of the light radiation of light illuminator and the optical parameter of near-nature forest light.
Above step discloses the specific implementation process of step S60, firstly, lighting respective numbers according to initial luminous flux ratio White-light emitting body and red emitting luminophores, adjust the luminous flux and red light-emitting of white-light emitting body respectively by adjusting driving current The light radiation of body, combination spectrum can change at this time, after debugging several times, shape (i.e. each wave of combination spectrum The relative spectral power of section) it is close in allowed band with natural light, confirm that spectrum is met the requirements at this time.
On this basis, optical parameter is checked, if optical parameter meets preset range, it is determined that obtain near-nature forest Light adjusts driving current if optical parameter is unsatisfactory for preset range repeatedly, meets the requirements optical parameter.
After spectrum and optical parameter meet the requirements, driving current is usually inconsistent at this time, in order to realize unified drive It is dynamic, subsequent adjustment need to be carried out, which is very long and complicated.Step S603 is carried out first:Adjust white-light emitting body And/or the driving current of red emitting luminophores, so that two driving currents is reached unanimity;When electric current is consistent, combination spectrum necessarily occurs Variation.In turn, step S604 is carried out:According to the variation of the relative spectral power of combination spectrum, white-light emitting body is further adjusted Luminous flux and red emitting luminophores light radiation, and monitor combination spectrum in real time, the object adjusted in this step is luminous flux Or light radiation, when the relative spectral power of combination spectrum meets preset range, the optical parameter of detection combination spectrum, when When optical parameter reaches preset range, confirmation obtains near-nature forest light.This is ideal situation.
However, relative spectral power is difficult to meet preset range, and optical parameter is also easy to appear wave after adjustment luminous flux It is dynamic.Therefore, it is also desirable to repeat step S601 to S605, driving current (being at this time fine tuning) is readjusted, is made opposite Spectral power and Optical Parametric meet preset range.Since during repeating step S601-S605, debugging be will do it every time Driving current is adjusted to consistent step, therefore, in multiple adjustment, electric current will gradually reach unanimity, to luminous flux and electricity The adjustment amplitude of stream will be gradually reduced, and will eventually get the near-nature forest for obtaining and meeting the requirements under driving current unanimous circumstances Light.
Further, in the optimization process of combination spectrum, it is understood that there may be following situation:By relatively repeatedly adjusting driving electricity Stream, still cannot be such that spectrum or optical parameter meets the requirements, at this time, it may be necessary to adjust the formula and/or concentration and/or thickness of fluorescent film Degree, then carries out step S601 again;Alternatively, the central wavelength of adjustment red emitting luminophores, then carries out step S601;Alternatively, increasing Add central wavelength to be different from the third illuminator of red emitting luminophores central wavelength, then carries out step S601.
According to the relationship of fluorescent film and the relationship of spectrum optimization, feux rouges and spectrum optimization, suitable mode tune can choose Whole prioritization scheme.In actual optimization process, it is related to the adjustment of fluorescent film, the adjustment of red emitting luminophores 522 and repeatedly The adjustment of multiple driving current and luminous flux, could obtain final result.
Finally, needing to record relevant parameter after debugging, which is used to provide for the manufacturing of light source necessary Information.
By above-mentioned optimization process, it is determined that above-mentioned white-light emitting body 521 and red emitting luminophores 522, and white-light emitting The actual ratio of the light radiation of the luminous flux and red emitting luminophores 522 of body 521 is 2~3:1, electric current be 20mA~100mA it Between, preferably 60mA.It is preferred that 1~4 light source in series of white-light emitting body 521 and 1~2 red emitting luminophores 522, single The power of light source is 0.5W or so.In the case that colour temperature is different, real data is slightly different.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
