Abstract

The invention discloses a remote fluorescent powder performance test device and a test method, and relates to fluorescent powder. The remote fluorescent powder performance test device is provided with an integration ball, a cosine collector, a blue light LED (light emitting diode) source, a light reflection cup, a fluorescent powder sheet/silica gel sheet, a TEC (triethyl citrate) temperature control clamp, a constant-current source, a spectrometer, a computer and a base, wherein the integration ball is fixed on the base and is provided with a light inlet and a light outlet; the cosine collector is connected with the spectrometer through an optical fiber at the light outlet and is used for collecting incident light; the output end of the spectrometer is connected with the computer and is used for spectrum collection and data analysis; the blue light LED source is connected with the constant-current source, serves as an exciting light source and is fixed on the TEC temperature control clamp, so that the stability of the light source is guaranteed through temperature control; the light reflection cup is fixed on the blue light LED source and achieves a light focusing effect; the fluorescent powder sheet/silica gel sheet is attached to the light reflection cup; the blue light LED source excites fluorescent powder to generate yellow light, and the yellow light and penetrating blue light are blended to synthesize white light.

Description

technical field [0001] The invention relates to fluorescent powder, in particular to a remote fluorescent powder performance testing device and testing method. Background technique [0002] Energy conservation and environmental protection are one of the themes of development in the new era. In the lighting industry, LED, as the most important and potential light source for future lighting, is being vigorously promoted and developed. With many advantages such as energy saving, environmental protection, color diversity and long life, LED has been applied in many industries such as backlight display, street lighting, urban night scene [S.Pimputkar, J.S.Speck, S.P.DenBaars, and S.Nakamura, Prospects for LED lighting, Nat. Photon., vol.3, no.4, pp.179–181, 2009.]. White light sources based on LED lamps are expected to replace traditional incandescent lamps and fluorescent lamps in the near future, becoming the main general lighting source in the future [M.R.Krames, O.B.Shchekin...
