120 Watt Flood Light Bulb Lumens – Fluorescent bulbs come in a range of colors. They herald the new era of the light bulb. The operation of fluorescent bulbs relies on the understanding of how atoms behave when they’re energized. This basic knowledge is used in all sorts of light bulbs. 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 releases this acquired energy in form of light photons. The photons might be of different colors depending upon the energy discharged. In a fluorescent bulb, there are two electrodes in the glass enclosure. The electrodes are connected to an AC current circuit. A little bit of mercury is also placed in the glass bulb, apart from an inert gas at low pressure.
When a current is passed through the electrodes and it’s warmed up, the enthusiastic electrodes move 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 farther billed. The highly charged electrons, which can also be highly unstable, discharge the photons.
Most of the light energy released is in the form of ultraviolet rays, which can be invisible to human eyes. |} The phosphorus which is coated on the interior of the bulb glows to produce visible light once 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 exact same present as incandescent lamps. They could provide many different colour ranges obtainable in other bulbs. Since they’re not affected by vibration, fluorescent bulbs can be safely used as enthusiast bulbs. Fluorescent bulbs do not become blistering popular and can be utilised in areas where fire safety is a concern.
