led_uses {photobiologyLEDs}

Spectral data for LEDs for different uses

Description

The collection of spectra leds.mspct contains spectra for light emitting diodes (LEDs) designed for specific uses as well as for general illumination. The character vectors described here contain the names of the spectra for LEDs sold for specific uses to facilitate their extraction from the collection. One additional vector, led_use contains the wording of uses as in the names of the spectra in the collection.

Usage

led_uses

plant_grow_leds

high_CRI_leds

Format

A vector of character strings.

An object of class character of length 7.

An object of class character of length 9.

Details

Most LEDs can be useful in different situations individually or in combination with other types. The lists are thus not exclusive but rather indicate a typical use.

Plant grow

The character vector plant_grow_leds contains the names of the spectra to facilitate their extraction from the collection. This includes LEDs designed to be the only light sources as well as LEDs designed to be used together with other LEDs to assemble luminaires used for plant cultivation, either as only light source or to supplement natural light.

High color reproduction index

The character vector high_CRI_leds contains the names of the spectra to facilitate their extraction from the collection. This includes white LEDs with a high color reproduction index (CRI > 95) as computed from the actual measured spectra. Nowadays some of these types of LEDs are not only advertised as good from illumination in museums, exhibitions and as light sources for video and photography, but also as less stressful to human vision and in some cases as good for the entraining of the human circadian clock. In practice this means an emission spectrum covering most of visible light with only minor peaks and valleys.
