20 Watt Led Flood Light Bulbs – Fluorescent bulbs come in a selection of colors. They herald the new era of the light bulb. The operation of fluorescent bulbs is based on the knowledge of the way electrons behave when they are energized. This basic knowledge is employed in all sorts of light bulbs. The electrons orbit the nucleus in different energy levels. When an atom is stimulated either due to heat (in case of incandescent bulbs) or another technique, the electrons jump to a higher energy level, further away from the nucleus.
The recently acquired energy in the electrode makes it unstable, and it releases this obtained energy in form of light photons. The photons may be of various colors based upon the energy released. At a fluorescent bulb, there are two electrodes in the glass enclosure. The electrodes are connected to an AC current circuit. A small amount 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 heated up, the enthusiastic electrodes proceed in the glass enclosure and a number of them collide with mercury traces. |} The mercury gets gaseous, and some of the charged electrons or atoms collide with the gaseous mercury and become further charged. The highly charged electrons, which are also highly unstable, discharge the photons.
Most of the light energy released is in the kind of ultraviolet rays, which can be invisible to human eyes. |} The phosphorus that’s coated on the interior of the bulb glows to produce visible light when the ultraviolet rays fall. Different combinations of photon coatings produce lights of different colours. Fluorescent bulbs are more effective than normal incandescent bulbs.
They produce more light for the same current as incandescent lamps. Thus, with reduced currents, they produce a similar intensity of light as incandescent bulbs and are energy-efficient. They can offer many different colour ranges unavailable in other light bulbs. As they are not affected by vibration, fluorescent bulbs may also be safely used as enthusiast bulbs. Fluorescent bulbs don’t become blistering popular and may be utilised in areas where fire safety is a concern.
