Question

What type of transformer is used in a 6V bed lamp?

Answer 1

Transformers are used for low voltage lighting systems, such as an Architectural track/monorail or landscape lighting system. Transformers convert standard residential electric current and transform it into a suitable current for your particular lighting system

Complete step by step answer:
As the household supply in India is 220V−240V AC so to use a bed lamp having rating 6V a step−down transformer will be required with a rectifier to convert 6V AC to 6V DC if the lamp is DC lamp. If supply at home is 240V, then we would be needing a transformer with a turn ratio $\dfrac{6}{{240}}$.

Transformer is what raises or reduces the wattage of lamps in your lighting system. It is a device that converts normal house current to the current required by a lamp, but be careful not to exceed the transformer’s maximum rating system because you will overload it. There are two types: magnetic & electric. Do not mix magnetic & electric transformers on the same dimming circuit.

The distance of your transformer from the system depends on the amount of wattage being used, the quantity of lamps, and an appropriate transformer to support your lighting system. The electronic transformer has the ability to push power down a line for 6 to 8 ft. on a low voltage system before requiring additional support. If a magnetic transformer is used for your lighting system keep in mind that it should be closer to the system to provide a sufficient amount of energy for all of your lamps.

Note: A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to "step up" or "step down" voltages and works on the magnetic induction principle.
