Foreword

This prestandard was prepared by NA 058-00-27 AA Effect of Light on Human Beings within the LightingTechnology Standards Committee (FNL) of the German Institute for Standardization DIN.

A prestandard is the result of a standardization work, which is not published as a DIN standard because ofcontents related reluctance or a deviant process of creation.

No draft preceding this prestandard was published.

Comments on experience with this prestandard are welcomed

best as an electronic file per e-mail addressed to [email protected] in chart form. A sample chart is ready for

Introduction

With the proof of melanopsin in ganglion cells of the human retina and their given sensitivity mainly in the bluepart of the spectrum it is clear that a description of optical radiation according solely to the photometric action

spectrum of DIN 5031-3 is not sufficient.

Depending on time of stimulation, narrow band light in the short wavelength region causes suppression of thenocturnal release of melatonin, increases heart rate as well as alertness and affects thermoregulation,electroencephalogram spectrum and the phase of the circadian system. Fast responses in the range of secondsto short wavelength light were seen in the papillary reflex or in brain activity patterns.

For these non-visual effects of light perceived by the eyes, the term biological effects is also used in thisprestandard.

As the available data base is partly unconfirmed, action spectra presented herein have to be updated accordingto new scientific evidence.

The importance of biological effects of light on humans justifies also in this early stage of evidence to compile aprestandard in order to have a uniform evaluation procedure.

1 Scope

This prestandard specifies the spectral quantification of visible optical radiation with respect to biological effectsof light. Additionally, terms and action spectra characterizing light biologically are defined.

The prestandard establishes a uniform evaluation of light sources and lighting, not implying necessarily that theaction spectra provide a precise measure for the biological effectiveness of the optical radiation.

The spectral characteristics of the illuminants in table 5 are defined in other standards. These are mainly

conventional light sources, while new applications make increasingly use of light emitting diodes (LED) withcolour temperatures between 2700 K and 7000 K and new fluorescent lamps with high colour temperatures.Therefore, table 6 contains typical biological action factors and age dependent correction factors for such lightsources. The underlying spectral distributions of the light sources are given in table A.1.

NOTE Above mentioned white LEDs produce a light mixture, composed of a primary blue component produced byelectroluminescence in the semiconductor and a broad spectrum yellow component produced by an overlying fluorescent

layer that converts part of the primary blue component. The given LEDs differ in composition of fluorescent phosphors and inspectrum of luminescence. LED types of different colour temperatures were gained e. g. by sorting of production output into

10


11/16

DIN V 5031-100:2009-03

different classes (binning). Depending on the manufacturer and type, LEDs may have different light spectrum while producingthe same light colour. Values in table 6 and table A.1 should therefore be regarded as typical. Similar considerations applyfor fluorescent lamps. They may also have different spectral distributions leading to a comparable light colour. The values intable 6 and A.1 may be seen as typical for recent fluorescent lamps with high colour temperatures.

4.3 Shifting of circadian phase

Humans own an inner clock, which - independently from external day-night-cycle - controls neuronal andhormonal processes in a so called circadian rhythm. The circadian rhythm affects the daily schedule of sleepand wake phases, release of melatonin and other hormones, and other physiological parameters of theorganism, like e. g. the body temperature. Light is capable of shifting the timing (phase) and changing thestrength (amplitude) of the circadian rhythm (see 4.4).

An action spectrum for shifting of the circadian phase is not available yet. Studies ([5]) suggest, that this actionspectrum is more likely to correspond with the action spectrum for melatonin suppression than with the spectralluminous efficiency function V() for photopic vision according to DIN 5031-3. Therefore equation (11) is defined:

scp() = sms() (11)

NOTE With equation (11), tables 3 and 4 as well as figure 1 apply correspondingly.

4.4 Change in circadian amplitude

The amplitude of the circadian system is affected by light analogously to 4.3. In consequence, the nocturnalmelatonin release is dependent on the preceding daytime light exposure, generally speaking in leading to highermelatonin release with more biologically effective light over the day. Though a respective action spectrum wasnot subject of studies in this regard, it may be assumed that this effect is controlled through the samephotoreceptors as the melatonin suppression. The action spectrum for change in circadian amplitude is definedby equation (12).

sca() = sms() (12)


4.5 Activation by light

Light exposure of the human retina increases subjective alertness. Such activating light effects have beenconsistently shown also for objective physiological parameters.

An action spectrum for activation by light is not available yet. Studies (see [6]) suggest, that this action spectrumis more likely to correspond with the action spectrum for melatonin suppression than with the spectral luminousefficiency function V() for photopic vision according to DIN 5031-3. Therefore equation (13) is defined:

sak() = sms() (13)


4.6 Treatment of seasonal affective disorders (SAD)

Light therapy shows considerable healing success in patients with seasonal depressions (SAD). Such patients,making up about 3 % of the population, show a higher sleep pressure, sense an increased need forcarbohydrates, feel sad and depressed, are often less productive, have higher error rates, tend to avoid contactsand show increased morbidity. They are free of symptoms from spring to fall [8]. Additional 9 % of the population([12]) sense a milder form of this interference and need no treatment (S-SAD). In total, 25 % of the generalpopulation feel seasonal variations in their mental state and behaviour [11].

11


12/16

DIN V 5031-100:2009-03

An action spectrum for treatment of seasonal affective disorders (SAD) with light is not available yet. Studies(see [7]) up to now do not support an action spectrum differing from the spectral luminous efficiency functionV() for photopic vision according to DIN 5031-3. Therefore equation (14) is defined:

sSAD() = V() (14)

NOTE With equation (14), the biological action factor is aSAD= 1. Age dependent correction factors can not bedetermined because the age distributionunderlying V() is undetermined.
