Course Content

The 2-year course has 2 intakes per year.
Cohort 1 runs from October-March and cohort 2 runs from March-October.

This introduces the student to the inspirational nature of lighting design through a series of images put together by one of the country’s leading lighting designers. Lighting is considered in terms of what is needed to see a task clearly; create mood; to assist with movement about a space; to reveal the architecture of the space and to play with perception. Light is also considered in terms of quantity and quality. You then learn how to create a design by understanding what is going on; how much light is required and what sort of contrast is needed for a particular task.

This module outlines the principles behind lighting design practice. We look at the different aspects which are drawn together in successful lighting design and the processes involved at all stages of a project.

We look at the variety of light sources and the way light is produced by various different forms of light sources (tungsten halogen, low- and high-pressure discharge lamps and LEDs); and the luminaires (light fixtures) that house these light sources and direct the light they produce to where it is needed.

This describes in simple terms the effect of light on a person. You will be introduced to the visual system; the eye and brain how they receive light and what that system does under changing conditions. Understanding this will enable the student to consider how much light is needed, contrasts between task and background and how light affects our health.

At its most basic level, as Isaac Newton showed, white light is a mixture of many wavelengths of light, each with their own characteristic colour - a feature which is replicated in every rainbow we see. In the fundamentals of light, we will also explore how we see, what affects this ability and how we ensure we have enough light to perform a task. This module is discussed in both objective and scientific terms; this includes the lighting units & language of light.

This introduces sunlight and daylight to the student. For most buildings daylight is the starting point for any lighting design so understanding what it is how it performs and how to estimate the amount is very important. Some buildings require the designer to prevent sunlight entering a space, how to deal with this and how to design for daylight are all covered.

This illustrates the different lighting techniques this module has been split into 5 sections covering lighting for offices, retail, Museums and galleries, leisure and a final miscellany of different building types. Extensive use is made of case studies to back up the explanation and techniques described.

Covers lighting controls, why we should use them and what are their benefits? What to avoid if they are not to be a nuisance. Can they save energy and improve health and well-being.

Visualisation and calculations using the DIALux 4 software, including both interior and exterior lighting scenes. This is in preparation for the exterior lighting assignment and the final design  project.

This module covers aspects of the more functional exterior lighting applications, including car parks, lighting for sports, & road lighting. It also includes what is obtrusive light and how to minimise it to protect the night-time environment.

This module is more aligned to the architectural aspects of exterior lighting, including landscape lighting, floodlighting of buildings and amenity lighting. A section on master planning is also included.

This module has an introduction by the Campaign for Dark Skies (CfDS) and will explore how light affects the natural world, environmental & ecological aspects of lighting and how this is affected by the built environment. This also covers impact assessment studies.

An introduction to the criteria for designing a emergency lighting installations and the legislative requirements.

This module is an introduction to the electrical aspects associated with lighting installations and includes the commissioning of lighting installations.
