Description of LED Fluorescent:

Many phosphors(Florescent Powder) tend to lose efficiency gradually by several mechanisms. The activators can undergo change of valence (usually oxidation), thecrystal lattice degrades, atoms – often the activators – diffuse through the material, the surface undergoes chemical reactions with the environment with consequent loss of efficiency or buildup of a layer absorbing either the exciting or the radiated energy, etc.


Festures of LED Fluorescent:

Phosphor layers provide most of the light produced by fluorescent lamps, and are also used to improve the balance of light produced by metal halide lamps. Various neon signs use phosphor layers to produce different colors of light. Electroluminescent displays found, for example, in aircraft instrument panels, use a phosphor layer to produce glare-free illumination or as numeric and graphic display devices. White LED lamps consist of a blue or ultra-violet emitter with a phosphor coating that emits at longer wavelengths, giving a full spectrum of visible light.

Q:what is pigment dispersion syndrome?
Pigment dispersion syndrome (PDS) is an affliction of the eye that, if left untreated, can lead a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor. This is not what causes problems; however, if the pigment flakes clog the trabecular meshwork, preventing the liquids in the eye from draining, pressure can build up inside the eye. This pressure can cause permanent damage to the optic nerve. This condition is rare, but occurs most often in Caucasians, particularly men, and the age of onset is relatively low: mid 20s to 40s. Most sufferers are nearsighted. There is no cure as of yet, but PDS can be managed with eye drops or treated with simple surgeries. If caught early and treated, chances of glaucoma are greatly reduced. Sufferers are often advised not to engage in high-impact sports such as long-distance running or martial arts, as strong impacts can cause more pigment cells to slough off
Q:thinking about the main role of pigments in photosynthesis...?
Green pigments absorb light in the red and blue parts of the spectrum and reflect the green back to our eyes. The major functional difference between chlorophyll and say jade green is that only the chlorophyll in living systems can transfer the absorbed light energy and the excited electron to another molecule, thus trapping it. In biology, pigment is any material resulting in color in plant or animal cells which is the result of selective absorption. Some biological material has so-called structural color, which is the result of selective reflection or iridescence, usually done with multilayer structures. Unlike structural color, pigment color is the same for all viewing angles. Nearly all types of cells, such as skin, eyes, fur and hair contain pigment. Butterfly wings typically contain structural color, although many of them contain pigment as well. Creatures that have deficient pigmentation are called albinos. In the coloring of paint, ink, plastic, fabric and other material, a pigment is a dry colorant, usually an insoluble powder. There are both natural and synthetic pigments, both organic and inorganic ones. Pigments work by selectively absorbing some parts of the visible spectrum (see light) whilst reflecting others. A distinction is usually made between a pigment, which is insoluble, and a dye, which is either a liquid, or is soluble. There is no well-defined dividing line between pigments and dyes, however, and some coloring agents are used as both pigments and dyes. In some cases, a pigment will be made by precipitating a soluble dye with a metallic salt. The resulting pigment is called a lake.
Q:what are the types of pigments?
INORGANIC PIGMENTS Oxides Chromates Sulphides Sulphoselenides Sulphates Silicates Ferrocyandies Carbonates Metallic Mixed Metal Oxides Vanadates ORGANIC PIGMENTS Organic pigments are generally categorized into six types : •Monoazo Pigments •Diazo Pigments •Acid and base dye Pigments •Phthalocyanine Pigments •Quinacridone Pigments •Other polycyclic Pigments if you want more detail: ORGANIC PIGMENTS: 1.AZO Pigments : Monoazo Yellow and Orange Pigments. Disazo Pigments. β-Naphthol Pigments. Naphthol AS Pigments (Naphthol Reds). Azo Pigment Lakes (Salt Type Pigments). Benzimidazolone Pigments. Disazo Condensation Pigments. Metal Complex Pigments. 2.POLYCYCLIC Pigments: Phthalocyanine Pigments. Quinacridone Pigments. Perylene and Perinone Pigments. Diketopyrrolo–Pyrrole (DPP) Pigments. Thioindigo Pigments. Isoindolinone and Isoindoline Pigments. 3. Anthraquinone Pigments. Anthrapyrimidine Pigments. Flavanthrone Pigments. Pyranthrone Pigments. Anthanthrone Pigments. 4. Dioxazine Pigments. Triarylcarbonium Pigments. Quinophthalone Pigments
Q:Oil paint: what's the pigment, binder, and vehicle?
Pigment is color in powder form. An example is lamp black; it was first made from the soot of kerosene lamps ground fine. Binder is a substance used to hold pigment together and make it adhere; in the previous example, linseed oil would be the binder for the lamp black pigment. Vehicle is a medium acting as a solvent, carrier, or binder for paint; turpentine or mineral spirits would be a vehicle but so would linseed oil as well to help dilute the paint and help it cover a large area. Hope that helps and thanx.
Q:What is a pigment and their function in photosynthesis?
chlorophyl is the pigment i think. it is in the leaves of plants, that is where the photosynthesis takes place.
Q:What is the importance of the accessory pigments?
Q:What is the difference between primary and accessory pigments?
primary pigments are the ones the electron involved in photosyn. goes to AFTER hitting the accessory pigs. in order to be sent to the electron transport chain. this is the case with photosystem 2 AND 1, they look like this: kvhs.nbed.nb.ca/gallant/biology/photosystem.jpg the green are accessory, and the blue is where the primary are. hope that helps...im a little rusty since i took AP bio last year.
Q:What is a pigment molecule?
pigments are molecules that absorb electromagnetic radiation. For example, the chlorophyll pigment in plants absorbs blue and red light, which is why they reflect green light (since green is the color not absorbed). Another example is melanin, which is the pigment that darkens the skin of people. Melanin absorbs UV to protect the skin. A pigment molecule struck by EM radiation in the visible region may absorb some of the light depending on what pigment it is.
Q:What is pigment?
mac pigments are multi use. they're probably most popular as eyeshadows, but can also be used on lips, cheeks, nails, and pretty much anywhere. the mac pro store sells several mixing mediums, to change the consistancy of the powder, for the different uses, or they can be mixed with water/visine/etc.
