Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

First referenceCompare with

LAMP LED

IEEE / ANSI

ANSI/IEEE led indicator lamp symbol

The LED indicator form identifies a documented panel indication assembly using a light-emitting semiconductor. Its rated input and any polarity requirement belong to the complete assembly rather than to an assumed bare LED.

Drawing use: Schematic
Application: Control circuits
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented LEDs functional form. Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

A panel LED indicator may contain internal limiting or protection components absent from a bare LED symbol.

LAMP LED

Symbols

LED indicator lamp

An LED indicator assembly provides a documented visual signal using a semiconductor light source. Its rated supply, polarity where applicable and indication meaning must be specified.

Drawing use: Schematic
Application: Control circuits
Reference family: IEC / Manufacturer

A distinction that matters

A rated panel LED indicator may contain internal circuitry beyond a bare light-emitting diode.
