ECE4809 · Solid state lighting

Overview

The unit introduces you to the new age of illumination using light-emitting diodes (LED) and their role in disruptive technologies such as human-centric lighting (HCL), horticultural lighting and visible light communications (VLC) alongside providing energy-efficient lighting. Topics include the basics of light, colour and human vision, radiometric and photometric descriptions of light, light quality measures, the characteristics of light-emitting diodes (LED), flicker, lifetime and reliability, LED drivers and the effects of light in the built environment in applications such as human wellbeing, plant growth and communication. Laboratories cover radiometric and photometric characterisation of light using a spectrophotometer, the use of standard illuminants, working with colour spaces, performing lumen and light spectrum measurements using an integrating sphere and the implementation of IoT-based smart lighting control.

Areas of study: Minor: Internet of Things (IoT)

Assessment

The Handbook lists an examination for this unit.

Continuous assessment: 50% Final assessment: 50% This unit contains a hurdle requirement that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Requisites

Learning outcomes

1. Apply appropriate theories to effectively design solid-state lighting or SSL systems, including the visual and non-visual effects, colour spaces, quality metrics, efficiency, LED characteristics and other aspects such as LED drivers, spectral sensors, smart lighting control and visible light communications of Li-Fi.
2. Assess the energy consumption of traditional versus SSL-based lighting approaches
3. Design and implement a system to solve a given complex engineering problem in the field of Intelligent lighting control using the knowledge of SSL.
4. Conduct experiments to investigate various relationships in photometry, radiometry, colour quality, the energy consumption of light sources and the implementation of IoT-based lighting control.
5. Assess critically the research literature in the field of solid-state lighting to evaluate recent findings and directions in SSL technology

Workload

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours of independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.

Student experience, not official rules. Nothing here changes what the Handbook says.
