Led Light Bulb For Aquarium – 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 how atoms behave when they are energized. This fundamental knowledge is used 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 because of heat (in case of incandescent bulbs) or some other procedure, 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 releases this acquired energy in form of light photons. The photons might be of different colors depending on the energy released. At a fluorescent bulb, you will find two electrodes inside the glass enclosure. The electrodes are connected 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 is heated up, the excited electrodes proceed in the glass enclosure and some of them collide with mercury traces. |} The germ becomes 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 that’s coated on the interior of the bulb beams to produce visible light once the ultraviolet rays fall. Various mixtures of photon coatings produce lights of different colors. Fluorescent bulbs are more efficient than normal incandescent bulbs.
They produce more light for the exact same current as incandescent lamps. They can offer a variety of colour ranges unavailable in other light bulbs. As they are not affected by vibration, fluorescent bulbs may also be safely used as fan bulbs. Fluorescent bulbs do not become blistering hot and may be used in places where fire safety is a concern.
