20 Watt Incandescent Light Bulb Lumens – Fluorescent bulbs come in a range of colors. They herald the new age of the light bulb. The operation of fluorescent bulbs relies on the understanding of the way electrons behave when they’re energized. This basic knowledge is employed in all types of light bulbs. An atom comprises a nucleus and electrons. The electrons orbit the nucleus in various energy levels. When an atom is excited either because of heat (in the event of incandescent bulbs) or another technique, the electrons jump to a higher energy level, farther away from the nucleus.
The recently acquired energy from the electrode makes it unstable, and it emits this obtained energy in form of light photons. The photons may be of different colors based upon the energy discharged. At a fluorescent bulb, there are two electrodes in the glass enclosure. The electrodes are attached to an AC current circuit. A little bit of mercury is also placed in the glass bulb, apart from a inert gas at low pressure.
When a current is passed through the electrodes and it’s warmed up, the excited electrodes move in the glass enclosure and some of them collide with mercury traces. |} The germ gets gaseous, and a few of the charged electrons or atoms collide with the gaseous mercury and eventually become farther billed. The highly charged electrons, which can also be highly unstable, release the photons.
Most of the light energy released is in the form of ultraviolet rays, which can be invisible to human eyes. |} The phosphorus that’s coated on the interior of the bulb glows to create visible light once the ultraviolet rays fall on them. Different combinations of photon coatings create lights of different colors. Fluorescent bulbs are more efficient than ordinary incandescent bulbs.
They create more light for the same present as incandescent lamps. They can offer many different color ranges obtainable in other bulbs. As they’re not affected by vibration, fluorescent bulbs may be safely used as enthusiast bulbs. Fluorescent bulbs do not become blistering hot and may be used in areas where fire safety is an issue.
