Abstract: Solid-state lighting devices including light-emitting diodes (LEDs) and more particularly LED chips and related methods are disclosed. LED chips are provided that include an indicia arranged between a primary light-emitting face and a mounting face of the LED chip. The indicia may include at least one of a logo, one or more alphanumeric characters, or a symbol, among others that are configured to convey information. Arrangements of at least one of an n-contact, a p-contact, or a reflector layer of the LED chip may form the indicia. LED chips are also provided where at least a portion of an indicia is arranged on a mounting face of the LED chip. Indicia are provided that may be visible through primary light-emitting faces when LED chips are electrically activated or electrically deactivated. In this regard, the indicia may be embedded within LED chips while still being able to convey information.
