Demonstrate knowledge of terms associated with illumination.
Performance criteria
1.1 Reflection factor is defined in terms of the proportion of incident flux that is reflected by a surface.
1.2 Absorption factor is defined in terms of the proportion of incident flux that is absorbed by a surface.
1.3 Transmission factor is defined in terms of the proportion of incident light that is transmitted through a material.
1.4 Glare is defined in terms of discomfort from excessive contrast.
Range - brightness contrast, colour contrast, direct, reflected.
1.5 Light output ratios are defined in terms of luminaire output and lamp output.
Range - total light output ratio, upward light output ratio, downward light output ratio.
1.6 Cut-off angle is explained in terms of direct glare cut-off.
1.7 Control of cut-off angle is described in terms of luminaire design.
Range - open luminaire, louvre-screened luminaire.
1.8 Photometric data of a luminaire are explained in terms of luminous intensity at various angles.
Range - illuminance cone, isolux diagrams, glare limitation curves, Cartesian diagrams, polar diagrams, space to height ratios.
1.9 Maintenance factor is defined in terms of appropriate allowance for deterioration of output and surroundings of a luminaire.
1.10 Utilisation factor is defined in terms of the proportion of lamp output reaching the working plane.
1.11 Key functions required to obtain quality in a lighting design are defined.
Range - safety of people; performance - illuminance levels, uniformity, glare;
appearance and comfort - colour temperature of light source, colour rendering, surface reflectance or luminance ratios, modelling.
Element 2
Design an area floodlighting installation for both horizontal and vertical areas of approximately 100 square metres each.
Performance criteria
2.1 Required illuminance value is determined from a lighting level guide, or from given data.
2.2 From given options, suitable luminaires are chosen for the type of application.
2.3 Design lumens of chosen luminaires are determined from a given table.
2.4 Number of floodlights required is calculated from given formula.
2.5 Spacing distances of luminaires are calculated for an even spread of light.
Element 3
Design a general indoor lighting installation for a room with a floor area of approximately 100 square metres.
Performance criteria
3.1 Required illuminance value is determined from a lighting level guide, or from given data.
3.2 From given options, suitable luminaires are chosen for the installation.
3.3 Design lumens of the chosen luminaires are determined from a given table.
3.4 The number of required luminaires is determined using the total lumen method and appropriate factors.
Range - illuminance required, room dimensions, room index, maintenance factor, utilisation factor.
3.5 The orientation and spacing of luminaires are determined using manufacturers' data.
Range - layout, longitudinal and transverse spacing factors. - Learning and Teaching Resource
