What is the deference between incandescent and fluorescent lights?
An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light. A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light. For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.
10 man-made sources of light?
1. Incandescent light bulb 2. Halogen light bulb 3. Compact fluorescent light bulb 4. Light emitting diode (LED) 5. Mercury vapor light bulb 6. Neon light 7. High intensity discharge lamps 8. Carbon arc lamp 9. laser 10. kerosene lamp
Where will a full range of colors be better seen in a room with fluorescent or outside under daylight?
Daylight will have a more complete spectrum. An interesting experiment is to hold a CD close to a fluorescent lamp. The CD will act as a primitive diffraction grating, and you'll see distinct blobs of colour - not a continuous rainbow spectrum. You're seeing the light emitted by the various phosphors in the fluorescent tube.
What is the full form of tube light?
tube light
A neon light is more similar to an incandescent light or a fluorescent light explain how you know?
A neon light is much more similar to a fluorescent light. I know because I have a Ph.D. in physical chemistry, but I suspect you mean "justify your answer," so here goes. In a gas-discharge light (a neon light), a gas is ionized by an electric potential. Free electrons are then accelerated through the ionized gas. This causes the ions to transition into an excited electronic state. When the ion decays back to the ground state, energy of characteristic frequencies is emitted; the dominant frequencies depend on the gas, the voltage, and the pressure. This is why neon lights are orange-red: the dominant characteristic visible frequencies for neon gas are in the orange-red portion of the spectrum. (If you see a "neon" light that isn't orange-red, it's probably not really using neon gas.) A fluorescent light is exactly the same, except that the inside of the tube is coated with a fluorescent material. It absorbs the (high frequency) energy emitted by the gas discharge itself, and emits energy at a lower frequency (characteristic of the specific material). The gas in fluorescent lights is usually low-pressure mercury vapor, whose dominant emisison frequencies are in the ultraviolet. This is absorbed by the phosphor in the tube and re-emitted as a lower frequency (in the visible spectrum). Most fluorescent lights have a mixture of phosphors so that the emitted light appears "white" because it's actually a mix of different colors that kind of "average out" to white (this is like how the red, green, and blue phosphors in a CRT "blend" to appear white). To confuse matters even further, a lot of modern "neon" lights are actually just fluorescent lights with a colored dye or sleeve applied to the tube (if the tube, when off, appears white, colored, or "cloudy", it's probably a fluorescent light instead; if it's clear and looks empty, then it's pure gas-discharge). This allows for the production of "neon" lights of any color desired and also allows different sections of the tube to have different colors. An incandescent light glows because it's hot ("black body" radiation or "cavity" radiation). There's no characteristic frequency, though there is an emissions maximum which varies depending on temperature. If it's relatively cool ("red hot" is relatively cool as used here), it will appear a dull red; as it gets hotter it turns bright red, then orange, then yellow, then white, and ultimately starts to appear to have a bluish tinge as the emissions maximum shifts to shorter and shorter wavelengths.
What are six main component of a fluorescent lamp tube light?
six main component of fluorescent tube light
You do not burn your finger when you touch a tube light?
If it's fluorescent, no.
What is life expectancy of fluorescent tube light?
3 years
What is a pin based fluorescent light fixture?
A pin based fluorescent light fixture is the type of fixture that takes fluorescent tubes. On each end of the fluorescent tubes there are contact pins. These pins are used to hold the tube in the fixture and to supply the voltage to the tube from the fixture's ballast.
When should you replace a fluorescent light bulb?
when the tube ends blacken after failure of the tube heaters
What type of light bulb converts ultraviolet waves into visible light?
A fluorescent tube does that.
How much is a fluorescent light bulb?
A four foot tube is about $4.95.
How does fluorescent work?
Fluorescent lights glow because of an electric discharge in a glass tube that causes mercury atoms to emit ultraviolet light. The inside of the tube is coated with phosphor, which absorbs the ultraviolet light and then re-emits visible light.
What is a good replacement for overhead fluorescent lights?
The best replacement is a new fluorescent light tube of the right voltage and power.
Which is hotter a fluorescent light tube or a light bulb?
By far the hottest of the two light sources is the light bulb.
What is principle of fluorescent tube light how choke gives transient voltage across tube at the time of starting?
11000
What combinations of light and hues make fluorescent colors?
You cannot make fluorescent colours simply by mixing any coloured paints. Fluorescent paints are fluorescent because they contain a substance that fluoresces. This means that the substance absorbs light or heat and then readmits it at a different wavelength (usually in the visible light range) when its atoms are excited. Such a substance is fluorescein, a fluorescent dye. Fluorescence is used in strip lighting where a substance called phosphor, which coats the inside of the tube, and which glows when subjected to fluorescent mercury vapour which is in the tube. Another substance, phenyl oxalate ester, glows in light sticks. Therefore, you can mix different colours as much as you wish, but they will never fluoresce unless the particular fluorescent substance is included with the paint pigment in the paint.
