Project Description

Light emitting diodes (LED) are the future of illumination due to their long life, non-toxicity, efficiency and tunability. However, there exists a noticeable gap between two groups of knowledge; one where the LED spectrum is tuned to achieve high visual quality (based on visual effects) and the other where the effects of light spectrum on the human body (non-visual effects) are being investigated. It is evident from recent medical research that light exposures on the retina can profoundly affect human health and wellbeing, but no effort has been made to include such factors into lighting design. Therefore, in this project, we aim to provide insight into the design of high quality LED­-based light sources with particular emphasis on the non-visual effects, in addition to perceived visual quality.

This project involves theoretical optimisation of light spectrum to maximise benefits to both the human visual perception and well-being of the human body. This will be followed by the design and implementation of spectrally tunable LED-based lighting systems to validate the optimisation results. The work will be carried out in the state-of-the-art Intelligent Lighting Lab at Monash University Malaysia ( It is also supported by the expertise and facilities of a local and a multinational company in the same industry.
