Led Outdoor Flood Light Bulbs 150 Watt Equivalent – Fluorescent bulbs come in a selection of colors. They herald the new era of this light bulb. The operation of fluorescent bulbs is based on the understanding of how atoms behave when they’re energized. This fundamental knowledge is used in all sorts of light bulbs. A molecule comprises a nucleus and electrons. The electrons orbit the nucleus in different energy levels. Once an atom is excited either due to heat (in the event of incandescent bulbs) or another procedure, 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 acquired energy in form of light photons. The photons may be of various colors depending upon the energy released. At a fluorescent bulbs, there are two electrodes in the glass enclosure. The electrodes are connected to an AC current circuit. A small amount of mercury can also be placed in the glass bulb, aside from a inert gas at low pressure.
When a current is passed through the electrodes and it’s warmed up, the excited electrodes proceed in the glass enclosure and a number 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 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 kind of ultraviolet rays, which are invisible to human eyes. |} The phosphorus which is coated on the interior of the bulb glows to produce visible light when the ultraviolet rays fall on them. Different combinations of photon coatings produce lights of different colors. Fluorescent bulbs are more efficient than ordinary incandescent bulbs.
They produce more light for the same current as incandescent lamps. They could offer a variety of color ranges unavailable in other light bulbs. As they’re not affected by vibration, fluorescent bulbs may also be safely used as fan bulbs. Fluorescent bulbs do not become blistering popular and may be used in places where fire safety is a concern.
