ledsavers.mspct: Spectra for a multichannel LED bulb

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.

Usage

ledsavers.mspct
ledsavers_channels
ledsavers_mixes
ledsavers_RG_mixes
ledsavers_RB_mixes
ledsavers_GB_mixes

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).

We thank Prof. Lars Olof Bj<U+00F6>rn for the gift of the lamp.

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:

• w.length (nm)

• s.e.irrad (relative energy based units)
