An overview fluorescent Fluorescent tubes are used for lighting in different contexts. They are most often in places like schools, offices, factories and shops where large areas must be illuminated efficiently.
Easily recognizable, fluorescent tubes are generally between 8.3 m long in most applications and have a diameter of about 3-4cm. Where they appear, they occur in large numbers. At work / school / company? Look them up. Fluorescent tubes.
The initial cost of fluorescent tubes is higher than incandescent lamps, but these costs are compensated with lower energy consumption and lifetime of the tubes.
Fluorescent tubes work differently than incandescent bulbs. Fluorescent tubes work by using electricity to excite mercury vapor ultraviolet light creates shortwave. This in turn causes a phosphor fluorescent create visible light. On the other hand, incandescent lamps work by passing a current through a thin filament, which heats the wire, causing it to glow and it produces light. The glass bulb prevents oxygen from reaching the hot filament, leading to oxidize.
Other than their useful life (which is 20 times longer than an incandescent light) and low energy consumption, emit fluorescent light more diffuse than incandescent bulbs, which distributes light more evenly without point glare source. Fluorescent tubes also emit up to 75% less heat than equivalent incandescent installation.
However, despite all the positives, there may be a risk to health posed by fluorescent tubes and must be handled and disposed of properly to minimize these risks. When a fluorescent tube is broken, a small amount of mercury is released into the air. Large quantities of mercury can cause tremors, emotional changes, headaches, and changes in nerve responses. So no need to worry too much, it is noteworthy because we all better than nothing like breaking expired fluorescent lamps with the rear leg of our friends when they are not looking.
When a fluorescent bulb is broken, the glass breaks into small fragments that can be dangerous and must be disposed of properly to avoid flying glass. glass splinters are painful and may cause infection if not treated.
In addition to the usual lighting applications, types of fluorescent tubes have been created for specific use in tanning beds. These tubes have a mixture of different phosphors than those used in the lighting situation, typically containing between 3 and 5 of the phosphorus. These lamps emit a quantity of UVA and UVB tanning causing a reaction on human skin.
Have you ever been to an amusement park? Did you go in the house ghost and the advice of your shining white laces and there was a funny spot on the jeans of your friend? This figure is lower than another type of fluorescent tube, the "Black Light '. Black lights work the same as standard fluorescent tubes even if they are coated with a special phosphor that converts UV light to shortwave longwave rather than the ultraviolet light that is visible to the human eye. Caution, however, insects are attracted to UV light so that I do not have one in your room if you like spiders.
