Identification markers for light-emitting diodes and related methods

Abstract

Solid-state lighting devices including light-emitting diodes (LEDs) and more particularly identification markers for LED packages and related methods are disclosed. Identification markers may include materials incorporated within LED packages that are transparent in a visible spectrum but detectable when illuminated with light outside the visible spectrum. When radiated with light outside the visible spectrum, identification markers may provide light in the visible spectrum. Alternatively, identification markers may provide light outside the visible spectrum that is detectable with equipment capable of detecting nonvisible light. Identification markers are generally configured to not be readily visible under inspection as a way to make LED packages more difficult for copying in counterfeit products.
