Multiple LED Sign Installations
Latest technology delivers the message on the ground
Scope of Work & Disciplines
The Pindari LED Sign Board Projects were located at Mining Area C at Jimblebar, Finucane Island and Nelson Point in Point Hedland.
In each case evaluation and specifications demanded the highest grade LED chip, exceptional display reproduction and the highest level of construction quality and fabrication.
The signs were the direct result of extensive End user and Manufacturer consultation. In developing the purpose built signs critical drive and manufacturing technology criteria were identified, addressed and demonstrated with modelling and presentations. Pindari worked closely with the manufacturer and client to ensure the end product met every criteria.
Critical requirement and specifications necessitated the latest in LED screen technology with assured longest technology lifecycle.
- NICHIA grade LED’s
- Colour range 4.4 trillion – Latest PWM drive technology
- 7mm virtual pitch technology – Image smoothing and hardware aliasing
- Displayable resolution 704 x 608 pixels
- Brightness: 6500cd/m2
- Viewing Angle: Horizontal: 110°; Vertical: 55°
- Refresh rate greater than 2400Hz
- Remote data upload capability
- Remote power management
The Works consisted of:
- Supply and Installation of 4.8m x 4.2m LED Communications Signs
- End to end construction including Supports, Footings and Underground services
- Supply and Install Power & Communication
- Commissioning, handover and client training
The typical inland maximum temperature range in summer is 37 to 42⁰C. Several days with 45⁰C + maximum temperatures occurring each year. The LED Sign were installed with air-conditioning upgrades specifically designed to handle the ambient temperatures encountered on site.
The Pindari Advantages
Pindari understand the critical nature of thermal management and applied a 5 stage Thermal Management Plan.
Thermal management is the single most important issue to screen preservation and longevity. The quality of the LED’s and the method in which they are installed and driven affect the rate of LED decay or degradation. However it is excess temperature that really accelerates the process of this degradation.
Additional Value Added Features
The signs have numerous technological features, including world leading switch mode power supplies manufacturer – Meanwell, to ensure longevity and best practical lifetime of the screens.
While these items are more expensive then generic power supplies, they prove to be more reliable, readily available and have maintained a quality benchmark.
All projects delivered with minimum 30% Aboriginal engagement, zero harm and zero incidents.
