2. comprehensive performance analysis system  for White light LED lamp with yellow phosphor, Trichromatic phosphor phosphor

3. Main functions: it is used to measure the photochromatic parameters of the relative spectral power distribution  color coordinate, relative color temperature, color display index, color tolerance, peak wavelength, half width of spectrum, main wavelength, red ratio, color purity, relative luminance  of yellow fluorescent powder of LED and t Trichromatic phosphor phosphor.it fully meets the requirements of CIE related standard and technical report.

White light LED lamp with yellow phosphor comprehensive performance analysis system adopts LED blue light as exciting light. The blue light is sharpened by the system, so that the excited luminescence is expected to be the desired narrow band blue (Δλ≈10 nm), and the blue light interference can be effectively filtered out by digital technology.

3. exciting spectra and thermal quenching analyzer for phosphor

Main functions: The EX-1000 exciting spectra and thermal quenching analyzer for phosphor can realize the measurement of excitation and eniiting spectrum property of phosphor, this property is benefit for the choosing of exciting source or improving the phosphor itself to achieve high conversion efficiency, and it can also measure the luminescent property of phosphor in their real work state(high temperature environment).

EX-1000 is a comprehensive measuring instrument for phosphor, which can provide comprehensive and objective measurement data for the development and quality control of rare earth three - color phosphor and white light LED lamp with rare earth yellow phosphor powder.
