A collection of LED emission spectra for the white LEDs in an Aralab plant-cultivation chamber at different nominal dimming settings.
Nichia_LED_RECOM_dim.mspctNichia_LED_RECOM_dim.mspct is a "source_mspct" object
containing a collection of 11 "source_spct" objects as members.
Members are named.
Nichia_LED_RECOM_dim.mspct contains a collection of
"source_spct" objects with spectral emission data for different
dimming settings. The entrance optics, a cosine diffuser, was kept at a
distance of 24 cm from light source. Thus, the different spectra are
comparable and provided expressed in calibrated spectral energy irradiance
units.
This growth chamber uses as light source a custom-built panel of Nichia Optisolis LEDs with CRI 97 rating based on LinearZ modules suplied by Lumitronix. Each LED module is driven by an RCD-48-.350 driver dimmed in constant current mode using a voltage supplied by the chamber controller.
The variables in each member spectrum are as follows:
w.length (nm)
s.e.irrad (\(\mathrm{W\,m^{-2}\,nm^{-1}}\))
Instrument used: Ocean Optics Maya2000 Pro single-monochromator array
spectroradiometer with a Bentham cosine corrected input optics. A complex
set of corrections and calibration procedure used. The source_spct
objects have attributes with additional information on the measurement and
data processing. Measurements done by Pedro J. Aphalo. Data acquired and
processed using R packages 'ooacquire' and 'photobiology'.
