The fluorescent film of optical chip and covering blue chip, red emitting luminophores 222 include red light chips；White-light emitting body 221 emits white
Light is mixed with the feux rouges that red emitting luminophores 222 emit, and feux rouges is used to compensate the red light portion that white light is lacked relative to natural spectrum,
Form quasi- natural light；The relative spectral power of red light is greater than 0.60 in quasi- natural light；The light relatively of cyan light in quasi- natural light
Spectral power is greater than 0.30；The relative spectral power of blue light is less than 0.75 in quasi- natural light.
Quasi- natural light LED light source in the present embodiment aims at the more close illuminating effect with natural light and has
Beauty-care physiotherapy function, and can reduce the ratio of blue light, is mainly manifested in relative spectral power more close to natural light, multiple
For optical parameter more close to natural light, feux rouges ratio is higher.
Such as Figure 10, the feux rouges relative spectral power that wavelength is 680~690nm is greater than 0.80；Wavelength is 622~680nm's
Feux rouges relative spectral power is greater than 0.60.Such as Figure 13 and Figure 16, traditional near-nature forest radiant can occur in the wave band after 640nm
The trend being decreased obviously.640-700nm feux rouges has excellent health care, physical therapy, beautification function.Also, pass through different-colour light
The test in source, when the colour temperature of quasi- natural light is 2700K-3000K, the relative spectral power of 640-700nm feux rouges is greater than 0.70；
When the colour temperature of quasi- natural light is 4000K-4200K, the relative spectral power of 640-700nm feux rouges is greater than 0.60；Quasi- natural light

Specifically, as described above, the basic support construction of quasi- natural light LED light source provided in an embodiment of the present invention is substrate
Layer 210, luminescence component are arranged on basal layer 210, and the quantity of luminescence component is one group, two or more groups, each luminescence component
Structure and function be all consistent.The present embodiment is preferably one group.Each group of luminescence component all includes 221 He of white-light emitting body
Red emitting luminophores 222, that is, it is by white light and red that quasi- natural light LED light source provided in an embodiment of the present invention, which issues quasi- natural light,
What the mixing of light was realized.Wherein, feux rouges is for compensating the part that white light is lacked relative to natural spectrum, and then is formed close to certainly
The quasi- natural light of right light.The white-light emitting body 221 includes blue chip and the fluorescent film for covering blue chip, red emitting luminophores
222 include at least red light chips, carry out wavelength convert by the monochromatic light that fluorescent film issues blue chip, generate its allochromatic colour
Light forms white light after a variety of Colored light mixings, forms quasi- natural light after the white light and feux rouges mixing.The quasi- natural light has following light
Parameter is composed, the relative spectral power of red light is greater than 0.60；The relative spectral power of cyan light is greater than 0.30；Blue light it is opposite
Spectral power is less than 0.75.Every group of luminescence component can issue quasi- natural light, thus it is provided in an embodiment of the present invention it is quasi- from
In the case that right light LED light source contains multi-group light-emitting component, quasi- natural light can be equally issued.
