In previous user-acceptance studies conducted at Aalto University, it was found that the preferred light-emitting diode spectral power distributions (SPDs) were not characterised by a high-CIE colour-rendering index but by a high-colour quality index (CQS) colour preference scale (Qp) and a high-CQS gamut area scale (Qg). In these studies, the SPDs were realised with a 12-channel LED spectra simulator. It is, however, foreseen that LED light sources consisting of 12 different types of LEDs will…

LED-based light sources optimised for high colour rendition from an end users’ perspective

The results of two experiments suggest that phosphor-converted LED lamps optimised for high colour rendition have the potential to outperform simple phosphors and even to measure up to traditional halogen lighting in terms of user preference.

Colour preference varies with lighting application

Numerous efforts have been made to investigate how to characterize the effect of light sources on colour preference. This paper describes a psychophysical experiment to compare the colour preference

Energy-Saving Light Source Spectrum Optimization by Considering Object's Reflectance

When an object is illuminated, part of the incident light is absorbed by the object that does not contribute to the illumination. If the light source's spectrum can be optimized by decreasing the

Colour preference, naturalness, vividness and colour quality metrics, Part 1: Experiments in a room

Criterion values of the indices for ‘good’ colour preference and vividness were determined to provide a usable acceptance limit for the spectral design and evaluation of light sources and correlated colour temperature turned out to be useful.

Change of Gamut Size for Producing Preferred Color Appearance from 20 to 15000 lux

ABSTRACT Numerous efforts have been made to investigate how light source color rendition affects color preference. Though the effect of light level on color appearance (known as the Hunt effect) was

Colour preference, naturalness, vividness and colour quality metrics, Part 3: Experiments with makeup products and analysis of the complete warm white dataset

Light source colour quality is a complex phenomenon with several visual and cognitive components. Subjective colour preference, naturalness and vividness assessments of reddish cosmetic products in a

Analysis of color rendition specification criteria

This article explores the ability of color rendition specification criteria to capture preferences for lighting color quality and recently proposed specification criteria using ANSI/IES TM-30-18 substantially outperformed all currently used specification criteria in identifying preferred lighting conditions.

Recommended methods for conducting human factors experiments on the subjective evaluation of colour rendition

This article explores the best practices for conducting psychophysical experiments that investigate how colour rendition influences the perception of architectural environments. We offer guidance

Modulation of the Intensity of the Spectral Components of Polychromatic Light within Certain Regions in Space by Passive Methods by Strategically Using Material Optical Properties and Texture

Recent research indicates that not only blue and green monochromatic light stimulates our circadian system, but polychromatic light as well. Recent work also suggests that the human circadian system



User preferences for LED lighting in terms of light spectrum

A study was carried out in light booths to investigate user preference for different light spectra and it seemed that light sources with a higher CQS Gamut Area Scale and CZS Colour Preference Scale values were preferred by the observers as far as LED spectra were concerned.

Subjective preferences and colour quality metrics of LED light sources

To understand people's judgement of the naturalness of object colours and preference for the lit environment, lighting booth experiments were conducted. Seven different LED spectral power

Light-emitting diode (LED)-based lighting systems seem to have considerable potential for use in shops and display units, where they may well outperform existing lighting systems.

Color rendering properties of LED light sources

A laboratory human factors experiment was conducted to understand the color rendering properties of various LED-based reading lights. Human subjects rated their preference for a given scene

Characterizing LEDs for general illumination applications: mixed-color and phosphor-based white sources

The rapid development of high-brightness light emitting diodes (LEDs) has made this technology a potential candidate for architectural lighting applications. There are two distinct approaches for

Color quality scale

The color quality scale (CQS) has been developed and uses many of elements of the CRI but does not penalize light sources for causing increases in the chroma of object colors but does penalize sources with smaller rendered color gamut areas.

Optimization of white polychromatic semiconductor lamps

A stochastic method of optimization of a white-light source that relies on additive color mixing of the emissions from colored light-emitting diodes (LEDs) was developed. The method allows for

Spectral design considerations for white LED color rendering

Multichip and phosphor-type white LED models were analyzed by simulation of their color characteristics and luminous efficacy of radiation, compared with those of conventional light sources for general lighting.

Correlation between color quality metric predictions and visual appreciation of light sources.

A negative correlation was found, between the capabilities of a light source's ability to predict appreciation and naturalness, indicating that a complete description of the color quality of aLight-Emitting-Diodes source probably requires more than one metric.
