Types of Fluorescent Lights
Simply put, fluorescent lighting is a kind of lighting technology which depends on a chemical reaction inside of a glass tube to create light. This chemical reaction involves gases and mercury vapor interacting, which produces an invisible UV light.
What is fluorescent lighting? Simply put, fluorescent lighting is a kind of lighting technology which depends on a chemical reaction inside of a glass tube to create light. This chemical reaction involves gases and mercury vapor interacting, which produces an invisible UV light.
Next, we have fluorescent lamps which are low pressure mercury-vapor gas-discharge lamps; these types of light use an electric current to stimulate the mercury vapor inside the lamp which produces UV (ultraviolet) light which then causes the phosphor material coating on the inside of the lamp to glow. The method of light production is known as fluorescence and is created when a specific material absorbs light or electromagnetic to produce light.
Types of Lighting: High-intensity Discharge Print High-intensity discharge (HID) lamps are similar to fluorescents in that an arc is generated between two electrodes. The arc in an HID source is shorter, yet it generates much more light, heat, and pressure within the arc tube.
While fluorescent (CFL) bulbs generate light by sending an electrical discharge through an ionized gas, incandescent bulbs emit light by heating the filament present in the bulb. When CFL bulbs were first introduced in the 1970s, they were expected to spell the end of the traditional incandescent light bulb.
Fluorescent. Fluorescnet Lamps generate light when an electric arc excites the gas in the tube. Mercury in the gas emits ultraviolet radiation causing the phosphor coating of the lamp to glow, or fluoresce. The glowing phosphors create white-colored light. Fluorescent lamps require a ballast in order to operate, as well as special lamp holders.
This is another form of discharge lighting just like fluorescent lamps. The tube is made of borosilicate glass to withstand pressure and temperature and contains some sodium metal, neon and argon. When the lamp is switched on, the sodium vaporises and an arc is established.
The light we see from a fluorescent tube is the light given off by the phosphor that coats the inside of the tube (the phosphor fluoresces when energized, hence the name). The light of a neon tube is the colored light that the neon atoms give off directly.
