We know thermal management
The technological development in the LED industry continues to advance at high speed and it is now possible to design automotive, street, work, industrial lights etc with excellent performance. The LEDs are now also at the stage that the price/performance ratio allows the technology shift to LED start on a broad scale.
To keep up with LED development new bearer technologies are required. The LED’s simply generate too much heat and using traditional printed circuit boards will cause the LED’s to overheat, degenerate or break. Both light output and colour temperature are dependent on the operating temperature of the LED.
Alunat is a printed circuit board material designed for use with LED-technology. It has a ceramic dielectric layer with high thermal conductivity. Alunat is developed by Aluwave and can reduce the operating temperature of temperature sensitive electrical components such as LEDs. Alunat has been developed and adapted in close cooperation with key customers.
The heat is in this way very efficiently transported away from the LED, allowing it to operate at lower temperature as opposed to a solution based on a thick polymer layer where the heat is locked to its source as described below.

To the right: a conventional solution with a heat concentration under the component.
The main benefits of Alunat are better technical performance (higher light output), reduced power consumption, increased reliability, prolonged service life and simplified design with reductions in assembly and component cost.
Aluwave also works with other material manufacturers and for each individual project the material with the right price/performance ratio is chosen.
