Lamps in electronics
Filament lamps have long been used as fast acting thermistors in electronic circuits. Popular uses have included:
- Stabilisation of sine wave oscillators
- Protection of tweeters
- Automatic volume control in telephones
Lamp circuit symbols
In circuit diagrams lamps usually are shown as symbols. For example, an electrician would not want to have to keep on drawing out light bulbs so symbols are used instead. There are two main types of symbols, these are:
The cross in a circle, which usually represents a lamp as an indicator.
The semi-circled dent in a circle, which usually represents a lamp as a source of light or illumination.
