Compact fluorescent lamps (CFL bulbs) first emerged on the lighting market as a more energy-efficient alternative to the incandescent light bulb.A CFL is just as energy efficient as the linear fluorescent tubes, but screws into the same socket as an incandescent.
What is the full FOrm of CFL for Class 7?
Compact fluorescent lamp(CFL) is a fluorescent light bulb that reduces wastage of electricity and can be fixed in the ordinary bulb holders.
What does CFL mean in lighting?
Compact fluorescent light bulbs
Similar term(s): Energy-saving lamps, Energy-saving light bulbs, Compact fluorescent light bulbs, CFLs. Definition: Compact Fluorescent Lamps (CFLs) are energy-saving light bulbs, which last longer and use far less energy than traditional (or incandescent) light bulbs for the same level of light intensity.
What is the unit of CFL?
The lighting efficiency in case of CFL, ranges from 45 lumen per watt to 60 lumen per watt. Since an incandescent bulb converts about 95 per cent of electricity into heat and only five per cent is converted into light, it generates only 14 to 16 lumen per watt.
What is CFL material?
CFLs use much less energy and last up to 10 times longer than standard light bulbs. What is in a compact fluorescent lamp (CFL) bulb? A CFL bulb is made of glass, a ceramic and metal base, a luminous powder called phosphor, and a small amount of mercury.
What is the full FOrm of CFL Class 6?
CFL Full FOrm – Compact Fluorescent Lamp.
What is full FOrm of CFL and LED?
Since 2014, government regulations have been pushing consumers to replace familiar incandescent light bulbs with more energy-efficient compact fluorescent lamp (CFL) and light-emitting diode (LED) bulbs.
What is CFL in Instagram?
“Canadian Football League” is the most common definition for CFL on Snapchat, WhatsApp, Facebook, Twitter, Instagram, and TikTok. CFL. Definition: Canadian Football League.
How does a CFL work?
When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. This UV light reacts with the fluorescent coating to produce the white, visible light you see when you turn on a CFL.Compact fluorescent bulbs contain small quantities of mercury.
What is the difference between CFL and LED?
To produce light, a CFL uses mercury vapour and phosphor while an LED lamp uses semiconductor material.A CFL is less energy-efficient as compared to an LED lamp.
Where are CFL used?
CFLs are highly versatile and can be used in any setting where you would normally use incandescent bulbs. They come in enough shapes and sizes that you can use them for recessed fixtures, table lamps, track lighting or ceiling lighting. Three-way CFLs and CFLs that work with dimmers are also available.
Which gas is used in CFL bulb?
In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.
What gas is in a CFL light bulb?
It contains a low-pressure mix of argon gas, mercury vapour, and liquid mercury, and is coated on the inside with three different phosphorous substances. The electrodes provide a stream of electrons to the lamp and the ballast controls the current and voltage flowing into the assembly.
What is the difference between CFL and fluorescent?
CFL is an acronym that stands for compact fluorescent light. Standard fluorescent lights are available in tubes (generally 48 to 84 inches in length). CFLs are much smaller.Fluorescent bulbs produce light by converting ultraviolet emissions with a fluorescent coating on the inside of the tube.
Does CFL emit UV?
Do CFLs emit UV? All fluorescent lamps emit some UV. Typical fluorescent lamps, including CFLs, which consumers would encounter, emit very low levels of UV. In order to measure any UV radiation from these lamps, very sensitive measuring equipment must be used.
What is a UVB lamp?
UV-B lamps are lamps that emit a spectrum of ultraviolet light with wavelengths ranging from 290320 nanometers.UV-B light does not tan the skin very much, compared to the UV-A lamps that are used in tanning beds.
What is the full form of CFL and MCB?
MCB = Miniature Circuit Breaker. 4. USB = Universal Serial Bus. 5. CFL = Compact Fluorescent Lamp.
What is the full form of CFC and CFL?
CFC stands for chlorofluorocarbons and CFL stands for compacr fluorescent Lamp.
What is the full form of CFL and LCD?
LCD – Liquid Crystal Display. MCB – Miniature Circuit Breaker. USB – Universal Serial Bus. CFL – Compact Fluorescent Lamp.
Which is brighter LED or CFL?
CFL’s or fluorescent light bulbs emit 60 lumens per watt. LED’s, however, are the most effective of all, with a whopping 72 lumens per watt. This means that for around 10 watts of power, an LED will be just as bright as a 60-watt bulb.
What is LED full name?
Light-emitting diode
