quartz lamp
Noun: A quartz lamp is a mercury-vapor lamp enclosed in a quartz container. The quartz material is used instead of standard glass because it can withstand much higher temperatures, allowing the lamp to operate more efficiently and produce intense ultraviolet light.
A quartz lamp is a specific type of electric lamp. It is used in contexts requiring a powerful and stable source of light, often rich in ultraviolet radiation. - The primary use is in scientific, medical, and industrial applications, such as sterilization, phototherapy, and certain manufacturing processes. - It is not typically used for general indoor lighting.
- The laboratory uses a quartz lamp to sterilize the surgical equipment.
- For his skin condition, the doctor recommended treatment with a quartz lamp.
- The intense UV output of the quartz lamp is crucial for the curing process in this factory.
- Technical Specification: The term often implies a lamp designed for its spectral output (especially in the UV range) and thermal durability, not just its physical composition.
- Historical Context: Early quartz lamps were significant advancements in lighting technology, enabling new applications in research and industry.
- Mercury-vapor lamp (n): The broader category of lamp to which a quartz lamp belongs. All quartz lamps are mercury-vapor lamps, but not all mercury-vapor lamps use a quartz envelope.
- Quartz tube (n): The cylindrical quartz container that encloses the lamp's elements.
- UV lamp (n): A general term for lamps emitting ultraviolet light; many UV lamps are quartz lamps.
- Mercury-vapor lamp (when context specifies the quartz enclosure)
- UV sterilization lamp (in specific applications)
The meaning of quartz lamp is highly technical and specific. It refers precisely to the lamp's construction (quartz envelope) and its typical function (as a mercury-vapor UV source). It does not refer to decorative lamps made of quartz crystal or to common household light bulbs.
