higanygzlámpák
Higanygzlámpák, or mercury lamps, are gas discharge lamps that generate light by passing an electric arc through mercury vapor contained within a sealed arc tube. The excitation of mercury atoms produces ultraviolet radiation, which in many designs is converted to visible light by a phosphor coating on the inner surface of the tube (as in fluorescent variants). There are two main families: low-pressure mercury lamps, used in fluorescent and compact fluorescent lamps, and high-pressure mercury lamps, used for outdoor and industrial lighting. Some variants rely more on direct UV or blue-green emission, while others use phosphor conversion to achieve different color appearances.
Operation and construction: the arc tube contains mercury and an inert gas to help start and sustain
Characteristics: higanygzlámpák are relatively energy-efficient compared with incandescent lamps and offer long service lives. However, their
Applications and history: mercury lamps played a major role in street and industrial lighting from the mid-20th
Environmental and safety notes: disposal and recycling are important due to mercury content; proper handling and
