A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.
1 paź 2024 · Fluorescent lamp, electric discharge lamp, cooler and more efficient than incandescent lamps, that produces light by the fluorescence of a phosphor coating. A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapour.
29 sie 2023 · The parts of fluorescent lamp and its function are very simple and easy to explain. Let’s take a look at each part and its function. 1. The Base: The base of a fluorescent lamp is the part that screws into the socket. It also helps to support the weight of the lamp and keep it steady. 2. The Arm:
23 lip 2010 · Traditional fluorescent lights have tubes shaped into straight cylinders. Compact fluorescent lights, CFLs, are fluorescent tubes bent in half like a letter "U" or bent into the shape of incandescent bulbs in a swirl. In "neon lights," the tubes are bent to form graphics or words.
24 lut 2012 · Fluorescent Lamp Definition: A fluorescent lamp is a low-weight mercury vapor lamp that uses fluorescence to produce visible light. Efficiency: Fluorescent lamps are more efficient than incandescent lamps, with a luminous efficacy of 50 to 100 lumens per watt.
7 lip 2021 · The fluorescent lamp (Fig. 1 (a) and Fig. 1 (b)) generally consists of a long glass tube (G) with an electrode at each end (E 1 and E 2). These electrodes are made of coiled tungsten filament coated with an electron emitting material.
There are three main types of fluorescent lamps: cold cathode, hot cathode, and electroluminescent. They all use phosphors excited by electrons to create light. On this page we will discuss the cold and hot cathode lamps. Electroluminescent lamps use "fluorescence" but are so different they are covered on another page.
