Understand the difference.

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

LAMP TX

IEEE / ANSI

ANSI/IEEE transformer-fed indicator lamp symbol

The transformer-fed lamp form identifies an indicator assembly with a documented internal voltage-conversion arrangement. Wiring uses the assembly input rating, while the internal lamp function explains the indication.

Form evidence

Autodesk IEEE-oriented Transformer Lights 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 lamp's built-in transformer is different from a separately supplied panel control transformer.
