leds.mspct: Spectral irradiance for diverse LEDs

Description

A collection of emission spectra of light-emitting-diodes from different suppliers.

Usage

leds.mspct

Arguments

Format

A "source_mspct" object containing 51 "source_spct" objects.

In each of the member spectra, the variables are as follows:

w.length (nm)
s.e.irrad (W m-2 nm-1)

Details

The "source_mspct" object contains "source_spct" objects with spectral emission data.

The variables in each member spectrum are as follows:

w.length (nm)
s.e.irrad (absolute or normalized).

When the exact distance from LED to cosine diffuser is not known precisely or when the driving current is unknown, the spectra have been normalized to spectral energy irradiance equal to 1 W m-2 nm-1 at the wavelength of maximum spectral irradiance. When the details of the measurement conditions are know, this are given and the data are expressed in absolute spectral irradiance units. In any case, it needs to be taken into account than even in these cases measuremnts have not been done in an optical bench, so values of expectral irradiance are subject to errors due to possible missalignment. The shape of the spectra, in contrast can be relied upon as measurements were done with well calibrated instruments.
