Embodiment Construction
[0033] As mentioned above, any color can be regarded as a certain spectral color and a reference light source (such as equal energy white light W E etc.) to mix and match the color, this spectral color is the dominant wavelength of the color, and the dominant wavelength of the color is equivalent to the hue of the color observed by the human eye. If the chromaticity coordinates of the light-emitting diode under test have been obtained, the equal-energy white light W E As a reference light source, the present invention is applied to quickly calculate its dominant wavelength.
[0034] Combine below Figure 5 and Figure 6 The specific implementation of the present invention is described in detail.
[0035] Figure 5 Among them, 1 is the light-emitting diode to be tested, and a series of discrete spectral data P(λ) are obtained by sampling the relative spectral energy = distribution function P(λ) radiated by 2 spectrometers to 1 light-emitting diode i ), i=1,..., 2048, 3 is ...
