My Flashcards

Definition

Meaning

An incandescent electric lamp whose filament is made of tungsten.

A term historically used to distinguish incandescent bulbs with tungsten filaments from earlier carbon-filament lamps; also used in technical contexts to specify the metal of the filament.

Linguistics

Semantic Notes

This is a compound noun. While 'tungsten lamp' is historically accurate and technically precise, in contemporary everyday usage it is often superseded by more generic terms like 'incandescent bulb' or 'filament lamp'. It emphasizes the material composition of the filament.

Dialectal Variation

British vs American Usage

Differences

No significant difference in meaning or usage between BrE and AmE. Both varieties understand the term.

Connotations

Technical, somewhat dated, evokes early-to-mid 20th century technology.

Frequency

Very low frequency in general discourse. Higher frequency in historical texts, technical specifications, or discussions of lighting technology history.

Examples

By Part of Speech

verb

British English

  • The vintage lighting system was designed to tungsten-lamp the entire hall.

American English

Examples

By CEFR Level

A2
  • This is an old tungsten lamp.
B1
  • Tungsten lamps use more electricity than new LED lights.
B2
  • The replacement of tungsten lamps with energy-efficient alternatives has reduced household power consumption significantly.
C1
  • Although superseded by solid-state lighting, the tungsten lamp's invention, utilising the metal's high melting point, revolutionised artificial illumination in the early 20th century.

Learning

Memory Aids

Mnemonic

Think: 'TUNGSTEN' sounds like 'TONGUE-STEN' - imagine a lamp with a glowing metal tongue (the filament) inside.

Conceptual Metaphor

LIGHT SOURCE IS A CONTAINER (of tungsten, heat, and light).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not translate 'lamp' as 'лампа' in the sense of a table lamp ('настольная лампа'). In this compound, 'lamp' refers specifically to the bulb/light source itself ('лампа накаливания').

Common Mistakes

  • Using 'tungsten lamp' to refer to any modern light bulb, including LEDs or CFLs.
  • Confusing it with 'halogen lamp', which is a specific type of tungsten-halogen lamp.
  • Incorrect spelling: 'tungston lamp', 'tungstun lamp'.

FAQ

Frequently Asked Questions

Not exactly. A halogen lamp is a specific, more efficient type of tungsten lamp that uses a halogen cycle to redeposit evaporated tungsten back onto the filament.

They are highly inefficient, converting most of their energy into heat rather than light. Regulations in many countries have phased out general-service incandescent lamps in favour of LEDs and CFLs.

Yes, but availability is limited. They are often sold for specialist applications (e.g., ovens, photographic lighting, certain scientific equipment) or as 'rough service' industrial lamps, not for general home lighting.

Its extremely high melting point (3422°C), which allows it to be heated to white-hot temperatures to produce light without melting.
