photobiologyLEDs: Spectral Data for Light-Emitting-Diodes
Spectral emission data for some frequently used light emitting diodes.
Data for emission spectra of different types of LEDs.
The package contains one collection of spectra for different LEDSs all of them measured at room temperature and a series of vectors to be used as indexes to extract different subsets of spectra. In many cases spectral data are normalized to spectral energy irradiance equal to one at the wavelength of maximum spectral energy irradiance (strongest emission peak).
None of the spectral data included in this package are based on supplier's specifications and are only for information. The exact emission spectrum depends to some extent on testing conditions, but more importantly among individual LED dies. Spectral specifications are usually given by typical and boundary values. Furthermore, most manufacturers classify LEDs of a given type into "bins" with slightly different optical and electrical characteristics. In other words, the data provided here are not a substitute for actual measurements of radiation emission and spectrum of the LEDs actually used in a given piece of scientific research. For less demanding situations the data are in most cases reliable enough but perfect agreement with measurements on other LEDs of the same exact type should not be expected.
