Fluorescent Lamp Parts

What is the purpose of the ballast in a fluorescent lamp?

• Increase energy efficiency

• Regulate current flow and provide necessary voltage for operation.

• Prevent overheating

• Illuminate the room

Describe the function of the starter in a fluorescent lamp.

• The starter in a fluorescent lamp adjusts the size of the lamp tube

• The starter in a fluorescent lamp controls the color temperature of the light

• The starter in a fluorescent lamp regulates the brightness of the light

• The starter in a fluorescent lamp initiates the flow of current through the lamp's tube by providing the initial high voltage needed to ionize the gas inside the tube.

Explain the role of the electrodes in a fluorescent lamp.

• The electrodes control the color temperature of the light emitted by the fluorescent lamp.

• The electrodes absorb light to create visible light in a fluorescent lamp.

• The electrodes emit electrons to produce ultraviolet light when voltage is applied, which interacts with the phosphor coating to create visible light.

• The electrodes regulate the temperature of the fluorescent lamp.

How does the phosphor coating on the inner surface of the lamp tube contribute to its operation?

• The phosphor coating emits a scent that attracts insects to the lamp tube.

• The phosphor coating converts ultraviolet light into visible light.

• The phosphor coating absorbs heat to prevent overheating of the lamp tube.

• The phosphor coating changes the color of the light emitted by the lamp tube.

What is the significance of the mercury vapor inside a fluorescent lamp?

• It helps regulate the temperature of the lamp

• It increases the lifespan of the lamp

• It emits ultraviolet light to excite the phosphor coating and produce visible light.

• It adds color to the light produced

Discuss the importance of the glass tube in a fluorescent lamp.

• The glass tube is filled with water to enhance the light output.

• The glass tube is used for decorative purposes only.

• The glass tube houses the mercury vapor and phosphor coating essential for light production.

• The glass tube is made of plastic to reduce costs.

What is the difference between a magnetic and electronic ballast in a fluorescent lamp?

• Magnetic ballasts are more energy-efficient than electronic ballasts.

• Electronic ballasts produce more flicker compared to magnetic ballasts.

• Both magnetic and electronic ballasts have the same energy efficiency.

• Electronic ballasts are more energy-efficient and produce less flicker compared to magnetic ballasts.

How does the cathode play a crucial role in the operation of a fluorescent lamp?

• The cathode absorbs light to produce energy for the lamp

• The cathode releases toxic fumes that enhance the light output

• The cathode acts as a cooling agent to prevent overheating of the lamp

• The cathode emits electrons when heated up, which then collide with mercury vapor in the lamp, causing it to emit ultraviolet light.

Explain the function of the filaments in a fluorescent lamp.

• The filaments in a fluorescent lamp are used to regulate the color temperature of the light emitted.

• The filaments in a fluorescent lamp help in controlling the brightness of the light.

• The filaments in a fluorescent lamp heat up and emit electrons, which collide with mercury vapor to produce ultraviolet light that is then converted to visible light by the phosphor coating.

• Filaments in a fluorescent lamp are responsible for generating heat to power the lamp.

Describe the process of ionization in a fluorescent lamp.

• Ionization in a fluorescent lamp occurs when the lamp is exposed to extreme heat

• Ionization in a fluorescent lamp is the process where mercury vapor is excited by an electric current, releasing ultraviolet light that then causes the phosphor coating to emit visible light.

• Ionization in a fluorescent lamp is the process of converting water into light energy

• Ionization in a fluorescent lamp involves the use of sound waves to generate light
