Overview

This unit of competency specifies the outcomes required to select and install light emitting diode (LED) systems into signs. It covers identifying the appropriate LED system to achieve job requirements, laying out and installing the system into position, and connecting and circuit testing the system to ensure consistent distribution of light.  The unit supports sign manufacturers producing illuminated signs. It applies to signs illuminated using LED technology, including light boxes and fabricated letters which, depending on how the modules are positioned inside the letter, will produce either face-illuminated or halo-lit signs.  Where LED lighting is less than 240 volts, no licensing, legislative, regulatory or certification requirements apply to this unit of competency at the time of endorsement. Should lighting be above 240 volts, relevant state and territory regulatory authorities should be consulted to confirm licensing, legislative, regulatory or certification requirements that apply to this unit of competency.

Assessment

For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

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, and;
  • 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, and;
  • test lights and correct any faults in light distribution.

Students will also be expected to demonstrate the following knowledge:

  • 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, and;
  • terminology used in manufacture of signs.

Required reading

The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by the Polytechnic and/or via the Polytechnic e-learning system.
