ledsavers.mspct: Spectra for a multichannel LED bulb

Description Usage Format Details Acknowledgements Note References Examples

Description

A collection of lamp emission spectra for a household LED bulb with four channels and a remote control allowing color mixing. In addition character vectors useful as indexes for extracting subsets of the data are defined. Pairs of RGB channels are used in mixes. This is by design of the lamp and/or its remote control. The lamp here used is a 7.6 W, 230 V, E-27 LED lamp bulb accompanied by a small wireless remote control from a Swedish supplier. Similar (identical?) lamps are at the moment (early 2018) widely available through eBay and Aliexpress sellers.

Format

ledsavers.mspct is a "source_mspct" object containing a collection of 16 "source_spct" objects as members. Members are named.

ledsavers_channels, ledsavers_mixes, ledsavers_RG_mixes, ledsavers_RB_mixes, ledsavers_GB_mixes are character vectors containing subsets of names(ledsavers.mspct).

Details

ledsavers.mspct contains a collection of 16 "source_spct" objects with spectral emission data for each of the colors obtainable from the lamp. All colors were measured at maximum power output although the lamp supports dimming. The lamp was maintained at the same distance from the input optics so the different spectra are comparable and provided expressed in calibrated units.

The variables in each member spectrum are as follows:

Note

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. Raw spectral data processed with R package MayaCalc. The source_spct objects have attributes with additional information on the measurement and data processing. Measurements done by Pedro J. Aphalo. Data acquired using R package 'ooacquire'.
