How does a fluorescent tube work?
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.
How do fluorescent and compact fluorescent lamps differ?
What’s the difference between a compact fluorescent light bulb and a fluorescent bulb? In addition, most compact fluorescent lamps have an “integral” ballast that is built into the light bulb, whereas most fluorescent tubes require a separate ballast independent of the bulb. Both types offer energy-efficient light.
How does a fluorescent light bulb work for kids?
How it works. An electric current is applied to mercury vapor inside the tube, causing it to emit ultraviolet (UV) light. A phosphor on the walls of the tube absorbs the ultraviolet light. This causes an electron to jump up to an orbital with a higher energy.
How does a compact fluorescent light bulb work quizlet?
How does a compact fluorescent light bulb work? Produces light by exciting atoms in a mix of argon gas and mercury vapors. An electrical current flows through the ballast and the gas-filled tube. The UV light then energizes a phosphor coating on the inside of the tube, which emits visible light.
How do fluorescent light starters work?
Simply put, fluorescent starters are a timed switch. The switch opens and closes until the fluorescent tube ‘strikes’ and lights-up. If the fluorescent tube does not light, the switch repeats it’s open/close cycle and the fluorescent tubes attempts to ignite again.
How fluorescent and compact fluorescent bulbs work describe how their operations and their spectra differ from those of incandescent light bulbs?
Fluorescent light wavelengths are shorter than incandescent light wavelengths and deliver a different kind of light to the eye. Fluorescent light is on what is called an emissions spectrum. This means that its wavelengths are punctuated by lines. An incandescent bulb is on what’s called a continuous spectrum.
What is the difference between other lamps and fluorescent lamp?
However, fluorescent bulbs last 10 to 15 times longer than that, up to 10,000 hours or more. This is turn leads to energy savings, so fluorescent bulbs are more environment-friendly….
| Incandescent | Fluorescent | |
|---|---|---|
| Light Production | Produces 15 lumens per watt of input power. | Produces between 50 and 100 lumens per watt. |
How do fluorescent light bulbs work simple?
Fluorescent lamps work by ionizing mercury vapor in a glass tube. This causes electrons in the gas to emit photons at UV frequencies. The UV light is converted into standard visible light using a phosphor coating on the inside of the tube.
How does a fluorescent lamp produce light quizlet?
A fluorescent bulb is a glass tube that contains mercury vapor. Inside, the glass is coated with phosphors. The electrons hit atoms of the mercury vapor, causing the mercury atoms to emit ultraviolet rays. The ultraviolet rays strike the phosphor coating on the inside of the tube and the atoms emit visible light.
What are fluorescent bulbs filled with quizlet?
What are the tubes of fluorescent light bulbs filled with? Mercury vapor and argon gas at low pressure.
How does the light in a fluorescent lamp work?
Fluorescent lamps work by ionizing mercury vapor in a glass tube. This causes electrons in the gas to emit photons at UV frequencies. The UV light is converted into standard visible light using a phosphor coating on the inside of the tube.
How are compact fluorescent lamps different from incandescent bulbs?
Compact Fluorescent Lamps (CFLs) are a low energy alternative to traditional incandescent bulbs. Instead of a tungsten filament, CFLs consist of a glass tube filled with mercury vapour and gas, with an electrode at either end of the tube.
How are ballasts added to compact fluorescent lamps?
An electronic ballast is also required to limit the current in the circuit and prevent damage to the lamp. In the case of fluorescent tubes and most commercial-type fluorescent lamps, the ballast is added to the lamp externally, in the circuit or built into the fitting.
How are the electrodes in a fluorescent lamp wired?
The tube has two electrodes, one at each end, which are wired to an electrical circuit. The electrical circuit, which we’ll examine later, is hooked up to an alternating current (AC) supply. When you turn the lamp on, the current flows through the electrical circuit to the electrodes.
