Abstract
A light emitting diode (LED) device includes a substrate, a light emitting diode (LED) die mounted to the substrate configured to emit electromagnetic radiation, a lens covering the (LED) die, and a lens protective structure configured to protect the lens and a lens bonding layer from electromagnetic radiation emitted by the light emitting diode (LED) die and from reflected electromagnetic radiation within the lens. The lens protective structure can also be configured to reflect electromagnetic radiation increasing light extraction from the (LED) device. A method for fabricating the (LED) device includes the step of forming an opaque lens protective structure on the lens or on the lens bonding layer configured to protect the lens and the lens bonding layer from electromagnetic radiation emitted by the light emitting diode (LED) die and from reflected electromagnetic radiation within the lens.
