Substrates for light emitting diodes and related methods
Last updated:
Abstract:
Light emitting diode (LED) devices, components and systems are provided. Improved substrates for LEDs and LED devices are provided, with one or more dielectric layers over a reflective layer sufficient to minimize or eliminate damage of the dielectric layer(s). More stable and efficient LED devices can be produced using such improved substrates. LED devices, and methods of making the same, are also provided wherein LED chips are embedded in fill material to attach the LEDs to a substrate and increase light reflectivity.
