Aspects of classroom lighting and décor that can promote discomfort and impair task
performance through glare, and imperceptible 100Hz flicker from fluorescent lighting, were …

This paper reviews current knowledge on non‐image‐forming aspects of vision.
Developments in the last 20 years have included the discovery of a fifth class of human …

Flicker has been an important lighting system consideration for over a century. More precise
terms are temporal light modulation (TLM) as the stimulus, and responses to TLM as the …

Typical home lighting practice is mainly centred on visual aspects to enable safe movement
between spaces, flexibility in multiuse spaces, a sense of aesthetics and energy efficiency …

This paper describes a multiphase pulsewidth modulation (MPWM) technique used for
controlling the luminance of a solid-state lamp (SSL). For a SSL consisting of multiple high …

Temporal light modulation (TLM) describes variations in light output from a light source or
lighting system and can be a characteristic of their normal operation. TLM at 100 or 120 Hz …

There is a drive to energy efficiency to mitigate climate change. To meet this challenge, the
UK Government has proposed phasing out incandescent lamps by the end of 2011 and …

Temporal modulation of lighting at frequencies higher than the critical fusion frequency can
affect human efficiency in diverse ways that are not understood. A simple visual search task …

With the advent of LED lighting systems, short-term psychological responses to temporal
light modulation (TLM) in offices have attracted considerable research attention in recent …
