Street Lighting Case Study

Take a look at our latest work and see what we can do for you.

Ultra-efficient custom optics and precision LED PCB assemblies achieve maximum pole spacing and 20+ year lifetime. Solutions for street lighting must meet highways standards and demanding lifetime targets. Our client needed to do just this, as well as reduce overall system costs and outperform the competition.

  • LED selection - to achieve lumen target and also work with custom optic
  • Thermal design to ensure efficiency and lifetime targets are met
  • Custom optic designed and manufactured to meet optical output pattern
  • Rigorous testing including photometric and IES, IK and third party UMSUG testing

Objective

Manufacture the highest performing, most thermally efficient solution that meets the highways specification (Class ME3a) and increases pole spacing whilst reducing system costs.

Considerations

  • Minimal LED count
  • Exceptional thermal efficiency
  • Exacting optical output pattern
  • IK impact resistance
  • Tight colour binning
  • Thermal interface between PCB and heatsink

Solution

An IMS PCB populated with Philips TX LEDs with a multiple bubble custom optic. Supplied with thermal gasket for greater thermal control and efficiencies.
