What is the meaning of fluorescent?
1 : giving out visible light when exposed to external radiation a fluorescent substance a fluorescent coating. 2 : producing visible light by means of a fluorescent coating a fluorescent bulb. 3 : extremely bright or glowing fluorescent colors.
What is the use of fluorescent lamp?
Fluorescent lamps are a lamp type that is commonly used to provide illumination for settings such as commercial lighting, industrial lighting, classroom lighting, and retail lighting. The sizes, light colors, and wattage of fluorescent tubes vary significantly.
What is fluorescent lamp and how does it work?
A fluorescent lamp generates light from collisions in a hot gas (‘plasma’) of free accelerated electrons with atoms– typically mercury – in which electrons are bumped up to higher energy levels and then fall back while emitting at two UV emission lines (254 nm and 185 nm).
What is an example of fluorescent light?
Fluorescent is defined as emitting light due to absorbing radiation from an external source, or something vividly colorful. A CFL light bulb that works through radiation is an example of a fluorescent light. A bright, vivid, colorful pink couch is an example of a fluorescent couch.
Is fluorescent glow in the dark?
Fluorescent colors appear intense in daylight but will not be visible in the dark unless exposed to a black light. Phosphorescent pigments will glow in the dark but only after being exposed to a light source, including sunlight or by placing under a light bulb. With no light source, fluorescent color has no color.
Why is it called fluorescent?
Fluorescent comes from the Latin fluere “to flow” — fluorspar can be added to welding compounds, for instance, to make them flow more easily. Florescent, without a -u-, means “flowering,” from Latin flor-, which is a completely different root.
What is the normal life of fluorescent lamp?
Typical Average Rated Life for Various Types of Bulbs
Incandescent | 750-2,000 hours |
---|---|
Fluorescent | 24,000-36,000 hours |
HID | 10,000-24,000 hours |
Compact Fluorescent | |
Plug-in | 10,000-20,000 hours |
What is the function of starter in fluorescent lamp?
Fluorescent starters or glow starters are used to help fluorescent tubes and lamps ignite in the initial starting stage of their operation. Simply put, fluorescent starters are a timed switch. The switch opens and closes until the fluorescent tube ‘strikes’ and lights-up.
What are the advantages and disadvantages of fluorescent lamp?
Pros and Cons of Fluorescent Lighting
- Pro — Energy Efficiency. One of the best benefits of fluorescent lighting comes from its energy efficiency.
- Pro – Cost Savings.
- Pro — Long Light Life.
- Con — Contains Mercury.
- Con — Higher Initial Cost.
- Con — Limitations.
Which is the best definition of a fluorescent lamp?
: a usually tubular electric lamp having a coating of fluorescent material on its inner surface and containing mercury vapor whose bombardment by electrons from the cathode provides ultraviolet light which causes the material to emit visible light Examples of fluorescent lamp in a Sentence
What makes light come out of a fluorescent lamp?
In most fluorescent lamps, a mixture of argon and mercury gas contained in a glass bulb is stimulated by an electric current, producing ultraviolet rays. These rays strike a fluorescent phosphor coating on the interior surface of the bulb, causing it to emit visible light.
How many volts does a fluorescent lamp use?
In an AC supply, the voltage drops 100 times a second to zero volts as the supply frequency is 50 Hz. When a Fluorescent lamp is operating with an AC supply, the light intensity drops 100 times a second.
What’s the difference between fluorescent light and LED light?
When you are trying to replace fluorescent lighting, whether, with LEDs or another tube, you will need to understand the difference between tube light sizes. Determining the tube size of the fluorescent light will help you decide which tube lighting is a suitable replacement.
