Fluorescent Black Light Bulb 23 – Fluorescent bulbs come in a selection of colors. They herald the new age of the light bulb. The performance of fluorescent bulbs is based on the understanding of how atoms behave when they are energized. This fundamental 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. Once an atom is excited either because of heat (in the event of incandescent bulbs) or some other technique, the electrons leap to a higher energy level, farther away from the nucleus.
The newly acquired energy in the electrode makes it unstable, and it emits this obtained energy in form of light photons. The photons might be of different colors depending upon the energy released. In a fluorescent bulbs, there are two electrodes inside the glass enclosure. The electrodes are attached to an AC current circuit. A little bit of mercury can also be placed inside the glass bulb, apart from a inert gas at low pressure. The interior side of the glass enclosure is coated with phosphorous.
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 some of the charged atoms or electrons collide with the gaseous mercury and eventually become farther charged. The highly charged electrons, which are also highly unstable, release the photons.
The majority of the light energy released is in the form of ultraviolet rays, which are invisible to human eyes. |} The phosphorus that’s coated on the interior of the bulb beams to produce visible light once the ultraviolet rays fall. Different combinations of photon coatings produce lights of different colors. Fluorescent bulbs are more effective than normal incandescent bulbs.
They produce more light for the exact 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 a variety of color ranges unavailable in other bulbs. Since they are not affected by vibration, fluorescent bulbs can also be safely used as fan bulbs. Fluorescent bulbs don’t become blistering popular and can be utilised in places where fire safety is a concern.
