Embodiment 1

[0051] like Figure 6 As shown, the present invention provides a method for realizing the light source of a solar simulator. The realization method adopts the first LED chip to emit light to excite the phosphor powder, and the phosphor powder emits light of different wavelengths, and then screens the spectrum of the light. The final light is synthesized and output; wherein, when the first LED chip emits light to excite the phosphor powder, multiple groups of different first LED chips are used to excite the phosphor powder; the realization method adopts the light emitted by the first LED chip and the light emitted by the phosphor powder. The light co-synthesizes the solar simulator light source.

[0052] It should be noted that the implementation method is not limited to the case of only the first type of LED chip, and in another embodiment, the implementation method includes using the first type of LED chip to excite the light obtained by phosphor powder and / or not The light ...

Embodiment 2

[0074] The technical solution of the second embodiment is the same as that of the first embodiment, and the difference lies in: 1) The light-emitting component of the second embodiment not only includes the first type of LED chips in the first embodiment and the first type of phosphor, It also includes the second type of LED chip with the second type of phosphor, so that the light generated in the second embodiment is a mixed light with a wide spectrum in the spectral range of 400~1100nm; 2) It is different from the first type of package in the first embodiment It is only the first type of LED chip package, and it is only a transparent packaging material that covers the surface of the first type of LED chip and is filled with the first type of phosphor powder in a certain proportion. In the second embodiment, the The first type of package is a first type of package that includes a first type of LED chip package and a second type of LED chip package, and the first type of packag...

Embodiment 3

[0097] The technical solution of the third embodiment is the same as that of the second embodiment, and the difference lies in: 1) The light-emitting component of the third embodiment not only includes the first light-emitting component in the second embodiment (that is, the first type of LED chip collocation The first type of fluorescent powder, and the second type of LED chip with the second type of phosphor), also includes the second light-emitting component (ie, the third type of LED chip), so that the light generated by the third embodiment has a spectral range of 300~ 1100nm wide-spectrum mixed light; 2) The package of the third embodiment includes the first package and the second package, both of which are a layer of transparent packaging material, and are separately packaged for three types of LED chips. In the third embodiment, only the differences from the second embodiment are described, and the same parts as the second embodiment are not repeated one by one.

Abstract

The invention provides a solar simulator light source and a realizing method thereof. The solar simulator light source at least comprises a substrate, a first lighting component and a light filter, wherein the first lighting component comprises a first kind of LED chips, a first kind of package bodies and fluorescent powder filled in the first kind of package bodies and corresponding to the first kind of LED chips. By combining electroluminescence of the LED chips with photoluminescence of the fluorescent powder and selecting the proper type of the LED chips to reasonably match with the broadband-spectrum fluorescent powder, light emitted by the LED chips can trigger the fluorescent powder while being combined with the same to form continuous broadband-spectrum light sources, and the light filter performs spectrum screening to obtain the continuous solar simulator light source good in matching with required application, so that the solar simulator light source can be widely applied to accurate simulation of solar continuous spectrum and realization of a broadband-spectrum near-infrared light source and the like.

Description

technical field [0001] The invention belongs to the field of special light sources, and relates to a fluorescent enhanced LED wide-spectrum light source, in particular to a solar simulator light source and a realization method thereof. Background technique [0002] Existing wide-spectrum light sources are mainly gas discharge light sources, such as xenon lamps, metal halide lamps, low-pressure sodium lamps, and high-pressure mercury lamps. There are disadvantages such as poor performance, high cost, and poor matching of luminescence spectrum with various natural light irradiation. Currently existing standard light sources, such as various D65 light sources, are significantly different from real sunlight. Energy-saving, miniaturized, long-life, and light sources with high spectral matching are the development direction of light source technology. [0003] In recent years, LED technology has developed rapidly and matured. The most important feature of LED is its high lumino...
