Assessment Requirements for CPCCSG3011 Install LED technology into signs

Modification History

Release 1.

This version first released with CPC Construction, Plumbing and Services Training Package Version 2.

Revised unit of competency. Replaces superseded non-equivalent CPCCSI3011A Use LED technology for signage, CPCCSI3012A Apply electrical theory for illuminated signage, and CPCCSI3013A Install LED systems.

Performance Evidence

A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit, and must select and install light emitting diode (LED) systems into three signs as follows:

two fabricated lower case ‘b’ in Helvetica font, measuring at least 600 mm high x 75 mm wide, and 100 mm deep and mounted to a white surface:

one must be face illuminated, with the face of the letter formed of opal acrylic and the back of the letter with a PVC foam backing

one must be halo lit, with the sides and face of the letter formed of non-illuminating cast acrylic and the back of the letter formed of clear acrylic

one freestanding back lit light box measuring up to 1800 mm x 300 mm x 100 mm, with an opal acrylic face.

In doing the above work, the person must:

identify and confirm client requirements for the finished job, including:

colour and brightness requirements

location for finished sign

quality and performance requirements of finished sign

lay out, install and secure the LED modules to each sign to ensure even and consistent lighting

test lights and correct any faults in light distribution.

Knowledge Evidence

A person demonstrating competency in this unit must demonstrate knowledge of:

application and use of:

safety data sheets (SDS) when working with LED components

safe work method statements (SWMS) when installing LED systems into signs

capacity of different surface types to absorb or reflect LED light

electrical theory relevant to selecting and using LED technology for signs, including:

processes to calculate maximum driver loading for LED modules

regulation of electrical current in LED systems

principles and application of design and layout theory relevant to sign manufacture, including:

balance

colour and colour harmony

contrast

use, application and limitations of red, green and blue (RGB) colour system in LED signs

limitations of sign manufacturer’s role when working with electrical components, including licensing and regulatory requirements applicable to working with electricity

pitch as it relates to positioning LED modules in fabricated letters and light boxes

requirements for working safely around power sources, services and assets

techniques for evaluating and using:

LED systems and packages

LED components

uses, applications and limitations of LED technology for illuminating signs, including:

colour types and limitations

components

durability

semi-conductor chip technology characteristics

systems and system packages

processes to manage heat generated by LED

terminology used in manufacture of signs.
