White Goods Illumination Case Study

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

Working with mains and low voltage supply options with the use of custom heatsinks, optical light guide technology and a fundamental understanding of LED technology, applications such as fuel bed oven cavity illumination have been achieved. We developed a halogen replacement for a domestic electric oven to provide maintenance free illumination of oven cavities.

  • LED selection and testing – high lumen device with tight colour bin control
  • Thermal and heatsink design for suitability in the application environment
  • Manufacturing process considered throughout design to meet thermal, cost and performance targets

Objective

To replace existing halogen lamp technology with highly reliable maintenance free LED technology.

Considerations

  • Long life expectation of 60 000 hours+
  • Tight colour (CCT) binning
  • High temperature application
  • Ease of assembly in mass production environment
  • Kanban mass volume supply model

Solution

Highly thermally conductive IMS PCB populated with single high lumen output LED in specifically select colour bin. Custom designed heatsink with high emissivity coating. Supplied with auto crimp wire PCB connection. Wire loom connectors and wire all industry standard high temperature rated.
