LIGHT ENGINE SYSTEM PREFERRED IN LED-BASED LIGHTING SYSTEMS

Problem: In the background of technology various type of PCBs structures are used to allow the use of multifunctional LEDs (light emitting diodes) in automotive industry applications. These examples have a common basic property, characterized in that they are related to apparatuses having only LED structures on PCB and having heat sinks or similar cooling apparatuses on the other side. Extra cooling designs developed for limited spaces, providing specific solutions with regard to automotive applications are needed.

Technology: The technology relates to cooling units developed in LED applications in automotive industry and it also uses advanced printed circuit board technologies that minimizes the heat resistance and renders heat conductivity more efficient and productive compared to standard printed circuit boards. 

Advantages:

•Eliminating local hotspots on the PCB

•Enabling dissipation of heat generated in PCBs over the board

•Creating a structure preventing the heating of PCB boards

•Extending useful operating life.
