Discharge Lamp
Definition
A discharge lamp refers to a type of electric lamp that produces light by discharging electricity through a gas, vapor, or metal. This illumination technology is widely used in various applications due to its efficiency and long lifespan.
Types
Discharge lamps come in different types, each offering unique characteristics and advantages. Some common types include:
- Fluorescent Lamp: A discharge lamp that uses phosphors to emit visible light when excited by an electric current. Fluorescent lamps are commonly used in homes, offices, and commercial spaces.
- High-Intensity Discharge Lamp (HID Lamp): A high-intensity discharge lamp that utilizes a pressurized arc discharge to produce light. These lamps are brighter and more energy-efficient compared to traditional incandescent bulbs. They are often used for streetlights, stadiums, and large indoor areas.
- Mercury-vapor Lamp: A type of discharge lamp that emits light when an electric current passes through mercury vapor. Mercury-vapor lamps find applications in outdoor lighting and industrial settings.
- Sodium-vapor Lamp: A discharge lamp that produces light by utilizing sodium vapor excited by an electric arc. Sodium-vapor lamps are commonly employed for street lighting.
Sample Sentences

- They installed high-intensity discharge lamps in the parking lot for better visibility at night.
- The mercury-vapor discharge lamp illuminated the large manufacturing facility.
- Replacing traditional bulbs with sodium-vapor discharge lamps greatly improved the street lighting efficiency.
