Outcomes and evidence requirements

Outcome 1

Demonstrate knowledge of light emitting diode (LED), fluorescent, and neon signage lighting systems.

Evidence requirements

1.1 Types of LED systems suitable for signage are described in terms of use, advantages, and disadvantages.

Competenz Ó New Zealand Qualifications Authority 2018 SSB Code 101571 NZQA registered unit standard 30156 version 1 Page 2 of 3

Range types – back lit panels, edge lit panels, channel lettering, reverse halo lit lettering, flex LED systems, module LED systems; advantages and disadvantages – colours, durability, weatherability.

1.2 Illumination requirements, and considerations for even illumination are explained for signage lighting systems.

Range module spacing, lumens per module, lumens per square metre (lux), panel or letter depth, LED lens angles, diffusion properties of acrylic panels.

1.3 Fluorescent lighting systems used for signage are described in terms of use, advantages, and disadvantages.

1.4 Neon lighting systems used for signage are described in terms of use, advantages, and disadvantages.

Outcome 2

Demonstrate knowledge of installation requirements for electrical components of signage systems.

2.1 Hazards of working with electricity are explained and the regulatory limitations for non-registered people working with electricity are explained as outlined in Schedule 1.1 and 1.2 of the Electricity (Safety) Regulation 2010.

Range prescribed electrical work, not prescribed electrical work, extra low voltage supplies.

2.2 Weathertighness ingress protection (IP) ratings are explained for electrical components. IP requirements are identified for components of LED signage systems.

2.3 Wiring requirements are described and basic electrical calculations are carried out for multiple LED lighting modules in terms of number and size of drivers/transformers (power supply modules or units and their ratings) required, and estimated total energy usage.

Range power, voltage, current.

Outcome 3

Fit LED systems into sign components.

3.1 LED system parts are selected and installed into sign components.

Competenz Ó New Zealand Qualifications Authority 2018 SSB Code 101571 NZQA registered unit standard 30156 version 1 Page 3 of 3

Range systems parts – flex LED system, module LED system, backlit panel, channel letter.

3.2 Wire connections are made and insulated.

Range solder, crimp, screw connectors.

3.3 LED modules are spaced to produce even illumination across the sign.

3.4 Sign illumination effect is bench checked prior to installation to ensure compliance with sign requirements.

Please note Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.

Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.

Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
