11 Watt Landscape Light Bulbs – Fluorescent bulbs come in a range of colors. They herald the new age of this light bulb. The operation of fluorescent bulbs relies on the knowledge of the way electrons behave when they’re energized. This basic knowledge is employed in all types of light bulbs. The electrons orbit the nucleus in various energy levels. When an atom is excited either 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 emits this obtained energy in form of light photons. The photons might be of different colors depending on the energy released. In a fluorescent bulb, there are two electrodes inside the glass enclosure. The electrodes are connected to an AC current circuit. A small amount of mercury is also placed inside the glass bulb, apart from a inert gas at low pressure. The inner side of the glass enclosure is coated with phosphorous.
When a current is passed through the electrodes and it is heated up, the enthusiastic electrodes move in the glass enclosure and a number of them collide with mercury traces. |} The mercury gets gaseous, and a few of the charged electrons or atoms collide with the gaseous mercury and become farther charged. The highly charged electrons, which are also 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 inside of the bulb glows to produce visible light once the ultraviolet rays fall on them. Various mixtures of photon coatings produce lights of different colours. Fluorescent bulbs are more effective than normal incandescent bulbs.
They produce more light for the exact same current as incandescent lamps. They can provide many different colour ranges unavailable in other bulbs. As they’re not affected by vibration, fluorescent bulbs can also be safely used as enthusiast bulbs. Fluorescent bulbs do not become blistering popular and can be used in places where fire safety is an issue.
