The International Energy Agency (IEA) 4E Solid State Lighting Annex is planning on conducting an Interlaboratory Comparison (IC 2022) for the measurement of temporal light modulation (TLM) from solid state lighting (SSL) products. This work builds on the SSL Annex’s experience from its previous two interlaboratory comparisons (IC 2013, IC 2017) for...
The applied numerical calculations to determine the stroboscopic effect visibility measure (SVM) of a specific temporal light modulation waveform will influence the uncertainty of the determined value. An investigation of the achievable uncertainty under application of zero-padding and quadratic interpolation for peak finding is performed. This is...
Daylighting offers environmental, economic and social benefits when applied successfully; however, poor use of daylight causes unwanted heat and glare problems that negate the desired benefits. In order to develop effective daylighting practices, a reliable method for assessing discomfort glare for occupants is required. The aim of this study was t...
The international focus on embracing daylighting for energy efficient lighting purposes and the corporate sector’s indulgence in the perception of workplace and work practice “transparency” has spurned an increase in highly glazed commercial buildings. This in turn has renewed issues of visual comfort and daylight-derived glare for occupants. In or...
Basal cell carcinoma is the most commonly occurring skin cancer in sub tropical climates. The link between ultraviolet radiation (UVR) and basal cell carcinomas (BCC) is strong. Numerous studies have investigated the spatial distribution of BCCs over the head and neck region and the relative UVR dose, with little or no correlation found between the...
People are exposed to varying amounts of UVR throughout their life from both natural and artificial light sources. The dose and rate of UVR exposure required for the formation of non-melanoma skin cancers is inconclusive. Certain regions on the face appear to exhibit a high rate of occurrence of Basal Cell Carcinomas (BCCs) in relation to the perce...
The daylighting of commercial buildings offers the opportunity to reduce energy consumption and improve occupant appraisal of the quality of their interior environment. The focus of this paper is the assessment of a light-redirecting device designed for use in a passive daylighting system for conventional, high-rise building façades. This paper pre...
Sunlight plays an etiological role in the formation of skin cancers [Phys. Med. Biol. 24 (1979) 931]. Non-melanoma skin cancers commonly arise in sun-exposed parts of the body, especially on the head and neck regions [Int. J. Dermatol. 34 (6) (1995) 398] although the amount of sun exposure that is required for the formation of skin cancers is still...
A survey conducted at the Queensland University of Technology investigated relationships between lighting in office buildings and, in particular, the contribution of natural light, and aspects of health and well-being of the office workers. The results highlight the desire for more natural light in the office environment and demonstrate that lighti...
