Publication Sponsored by the Society's Colour Measurement Committee — XIV The Impact of Modern Lighting on the Dyer

Until recently, the two desirable characteristics of high lamp efficacy and good colour rendering were mutually exclusive in fluorescent lamps but in 1971 calculations were made which showed that they could co-exist if the emitted light approached a 3-line spectral power distribution (SPD), ideally the emission bands being at 450, 540 and 610 nm. The discovery of new phosphors has made such lamps a practical possibility and two manufacturers have marketed lamps whose SPDs lie between the continuous SPD of conventional lamps and the 3-line ideal. Such lamps have been found to render many objects more colourful than any conventional lamps and thus more acceptable to the average observer. This combination of desirable characteristics suggests that such lamps may become the most common form of artificial lighting, especially in view of the need to conserve fossil fuels. Tire installation of one of these lamps in a large department store, however, caused some serious problems with textiles which were metameric matches. These may be more serious with sources whose SPDs are closer to the 3-line ideal. The same problems will also occur with nontextile materials, e.g. ceramics and plastics, which match under various conventional sources. These developments in lighting may make extensive re-matching necessary.     

Evaluation of discomfort glare from color leds and its correlation with individual variations in brightness sensitivity

The light‐emitting diode (LED) has attracted attention as an alternative light source to fluorescent and incandescent lighting. The characteristics of LED light are different from other sources, but regulations for LED products have not been completely established. Common LED lights, such as automotive lamps, street lighting systems and traffic lights, are produced under the existing glare regulations for other light sources, and some organizations are seeking to establish standardized regulations for LED products. Glare can impair vision and cause discomfort and must be considered when establishing regulations for lights. In this study, we measured the sensitivity of observers to the discomfort glare from color LEDs and analyzed the correlation between discomfort glare sensitivity and brightness sensitivity using heterochromatic brightness matching and flicker photometry. The results indicate a correlation between discomfort glare sensitivity and brightness sensitivity using blue LEDs and mild correlations with green and red LEDs. © 2010 Wiley Periodicals, Inc.

Advancement in materials for energy-saving lighting devices

This review provides a comprehensive account of energy efficient lighting devices, their working principles and the advancement of these materials as an underpinning to the development of technology. Particular attention has been given to solid state lighting devices and their applications since they have attracted the most interest and are the most promising. Solid state lighting devices including white light emitting diodes (LEDs), organic LEDs (OLEDs), quantum-dot LEDs (QLEDs) and carbon-dot LEDs (CLEDs) are promising energy efficient lighting sources for displays and general lighting. However there is no universal solution that will give better performance and efficiency for all types of applications. LEDs are replacing traditional lamps for both general lighting and display applications, whereas OLEDs are finding their own special applications in various areas. QLEDs and CLEDs have advantages such as high quantum yields, narrow emission spectra, tunable emission spectra and good stability over OLEDs, so applications for these devices are being extended to new types of lighting sources. There is a great deal of research on these materials and their processing technologies and the commercial viability of these technologies appears strong.     

Alternatives to Outdoor Daylight Illumination for Photodynamic Therapy—Use of Greenhouses and Artificial Light Sources

Daylight-mediated photodynamic therapy (daylight PDT) is a simple and pain free treatment of actinic keratoses. Weather conditions may not always allow daylight PDT outdoors. We compared the spectrum of five different lamp candidates for indoor “daylight PDT” and investigated their ability to photobleach protoporphyrin IX (PpIX). Furthermore, we measured the amount of PpIX activating daylight available in a glass greenhouse, which can be an alternative when it is uncomfortable for patients to be outdoors. The lamps investigated were: halogen lamps (overhead and slide projector), white light-emitting diode (LED) lamp, red LED panel and lamps used for conventional PDT. Four of the five light sources were able to photobleach PpIX completely. For halogen light and the red LED lamp, 5000 lux could photobleach PpIX whereas 12,000 lux were needed for the white LED lamp. Furthermore, the greenhouse was suitable for daylight PDT since the effect of solar light is lowered only by 25%. In conclusion, we found four of the five light sources and the greenhouse usable for indoor daylight PDT. The greenhouse is beneficial when the weather outside is rainy or windy. Only insignificant ultraviolet B radiation (UVB) radiation passes through the greenhouse glass, so sun protection is not needed.     

Nanocrystallized Organic Thin Films as Effective Light Outcoupling Layers for Organic Light-Emitting Diodes

Light outcoupling from organic light-emitting diodes (OLEDs) is essential for developing energy-saving displays and efficient lighting sources. Nanocrystallized organic thin films exhibiting scattering features have been considered as effective light extractors for OLEDs. This paper reviews recent advancements in nanocrystallized thin films and their applications in OLEDs. Due to the advantages of easy preparation and OLED compatibility, nanocrystallized organic thin films can integrate with OLEDs as external or internal light extractors easily. Significant light enhancement has been achieved. The fabrication methods and mechanisms of light enhancement are discussed.     

Development of efficient and durable sources of white light

This review presents a brief history of the development of light sources over the centuries to provide one of the human race’s basic needs – light. Recent moves in Europe to encourage the adoption of compact fluorescent lamps as more energy‐efficient replacements for incandescent lights, despite certain drawbacks, are described. Rapid strides are now being made in the development of solid‐state ‘white’ lights which are already sufficiently durable and efficient to warrant adoption for both domestic and public lighting purposes. Their basic construction and comparative performance, properties and uses are fully described, together with the many ideas for improving their brightness and durability still further. Solid‐state devices offer additional savings compared with those which should be achieved under the EU’s targeted replacement of incandescent lights by 2012, and later one can expect such devices to compete with high‐pressure sodium luminaires for street lighting.
