Abstract
The invention relates to a structure of a light-emitting diode with high color rendering index, belonging to electrics. At least one light-emitting element, at least one red light-emitting element and at least one green light-emitting element are arranged on a substrate, wherein the light-emitting elements radiate blue light sources and simultaneously excite fluorescent powder coated on the outside of the light-emitting elements so as to generate white light; the white light is mixed with red light radiated by the red light-emitting element and green light radiated by the green light-emitting element to generate a light source with high color rendering index; and by adding light source bodies of the red light-emitting element and the green light-emitting element, the projection effect of light tends to be the color of natural light, an object to be radiated can obtain perfect color rendition and the comfort and the harmony of human body impression can be further improved without generating the phenomenon of distortion of objects.
Description
Technical field
The present invention relates to electric information, be particularly related to a kind of structure of high color rendering light emitting diode, refer to that especially a kind of height object true colors that obtains reappears effect and improves human body impression comfort level and harmony and can not allow the structure of high color rendering light emitting diode of object color distortion.
Background technology
Along with the LED development of technology, the aspect that LED uses is more and more extensive, become luminescence component indispensable in the daily life, especially be subjected to the energy starved influence, more and more Duo luminous product all emphasizes to possess the effect of power and energy saving, and LED is with plurality of advantages such as power saving, high-effect, high brightness, changeableization, attractes attention being subjected to all circles especially in recent years.
Though LED lamp miscellaneous source, light fixture constantly push away layer and make new advances, nonetheless, LED still can't become the lighting apparatus of main flow at present, its most important reason:
1, the color rendering deficiency of white light LED, because of applying the yellow-green fluorescence powder outward by blue light crystal, white light LED forms, utilize blue-ray LED to excite yellow-green fluorescence green-yellow light that powder produces, with unexcited blue light mixed light generation white light itself, its three sources light ratio example is inhomogeneous, the light color rendering is had a greatly reduced quality, and then the feasible thing that thrown light on can't show original tone.
2, colour temperature is higher and wayward, and because of the light emitting source of white light LED is a blue light crystal, so the colour temperature of its white light is higher, with regard to vision, common people can feel that the light tone is blue partially.
For improving the shortcoming of above-mentioned white light LEDs, most of manufacturer utilizes blue-ray LED to excite green light fluorescent powder and red light fluorescent powder, after two kinds of fluorescent material are excited, produce green glow and ruddiness with the blue light that originally was used to excite complementary and generation white light, improve the shortcoming that the white light color rendering is not good and colour temperature is higher, but the shortcoming of this kind method is that the efficient of red light fluorescent powder is low, must more at high proportion red light fluorescent powder for increasing color rendering, however this measure causes brightness to reduce again.In view of this, some manufacturer is for improving the LED color rendering, on the LED Design of Luminaires, utilize to be coated with outside the blue-ray LED and be covered with yellow-green fluorescence powder generation white light, and then add that red LED increases color rendering, and guarantee that brightness is unlikely to reduce, though this way can achieve the goal, also only be confined to the lower white light of colour temperature.
Summary of the invention
The object of the present invention is to provide a kind of structure of high color rendering light emitting diode, solve light-emitting diode and how to improve human body impression comfort level and harmony and can not allow the problem of object color distortion.
A kind of structure of high color rendering light emitting diode comprises:
One substrate;
At least one illuminating part, this illuminating part is located at this substrate, and this illuminating part radiation blue-light source, and excites the outer fluorescent material that applies of this illuminating part to produce white light simultaneously;
At least one red light-emitting spare, this red light-emitting spare are located at this substrate, and radiation red-light source while and this white light mixed light; And
At least one green luminescence spare, this green luminescence spare are located at this substrate, and radiation green-light source while and this white light and this ruddiness mixed light.
Wherein this illuminating part is that blue chip excites yellow fluorescent powder generation wavelength to form between the blue light of 430nm to 480nm between green-yellow light and the wavelength of 545nm to 585nm;
Wherein the red light wavelength of this red light-emitting spare is between 595nm to 640nm;
Wherein the green wavelength of this green luminescence spare is between 500nm to 550nm;
Wherein this fluorescent material is the yellow-green fluorescence powder;
Wherein this illuminating part is a white light emitting diode;
Wherein this red light-emitting spare is a red light-emitting diode;
Wherein this green luminescence spare is a green light LED.
The invention has the advantages that: the light source body of utilization interpolation red light-emitting spare and green luminescence spare two classes makes the color of the projection effect convergence natural daylight of light, make illuminated object can obtain perfect color rendition, and then the comfort level that improves the human body impression can not allow the situation of object generation distortion with harmony.
