Human-centric lighting

Human-centric lighting The fast growth of technology in artificial lighting viewed against the background of capitalism has meant it inevitable that attention has been focussed far closer on lighting as a functional necessity with which to illuminate a space with far less emphasis on the qualities of the light source and its possible effects on human wellbeing. Since 1991, when Dr Russell Foster of Oxford University led the team that discovered photosensitive retinal ganglion cells in the eye, which are key to controlling our circadian rhythm, a cultural movement of redefinining the quality of lighting and the usage of it is assuming more importance in lighting design – human-centric lightin

Circadian rhythm

Circadian rhythm Human beings have an internal clock that is intrinsic in our brain, which shifts between alertness and sleepiness at regular intervals. This phenomenon is known as circadian rhythm and it has a central role in sleep/wake cycle regulation. The release of melatonin which promotes sleep onset is regulated by the central circadian rhythm generator. (Khullar, A. 2012, The Role of Melatonin in the Circadian Rhythm Sleep-Wake Cycle, Psychiatric Times, available at For millenia humans have lived synchronised with the natural cycle of light and dark, with the majority waking up after sun

And, lighting can cause us to strongly dislike a room which we would otherwise find appealing.” How do we create light effects that enable us to stimulate cognitive and emotional human responses? We are surrounded by light. Ephemeral light constantly fluctuates around us, in our spaces, in our memory and in our emotions. We are part of a co-created picture constituting of light patterns created by differe
