Description of LED Fluorescent:
Extensive usage: it applies to various LED encapsulation from cool white to warm white. The rendering index can be up to 98 with red powder.
Festures of LED Fluorescent:
Fluorescent powder or Phosphors are often transition metal compounds or rare earth compounds of various types. The most common uses of phosphors are in CRT(cathode ray tube) displays and fluorescent lights. CRT phosphors were standardized beginning around World War II and designated by the letter "P" followed by a number.Phosphorus, the chemical element named for its light-emitting behavior, emits light due tochemiluminescence, not phosphorescence.

- Q: Why do algae contain pigments other than just chlorophyll?
- they stay underwater...the water swollows easy in a definite sequence, so the deeper they stay the greater distinctive is the easy and that they elect different pigments than landplants.
- Q: A.catalyzes chemical reactions.B.absorbs light.C.transports materials.D nverts energy to light.E s energy.
- In biology, a pigment is any colored material of plant or animal cells. Many biological structures, such as skin, eyes, fur and hair contain pigments (such as melanin) in specialized cells called chromatophores. Many conditions affect the levels or nature of pigments in plant, animal, some protista, or fungus cells. For instance, Albinism is a disorder affecting the level of melanin production in animals. Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well. So pigment reflects color and absorbs light.
- Q: i love makeup so mucch im like addicted...lol but the only thing is that i only buy that department or drug store brands cause i cannot afford high quality brands. the one that i buy are good for me,,but anyways i was wondering what the heck is mac eyepigment,,what is the diffrence between eyeshow and pigment? pleas help thank u,,,oh yeah and what does it look,like on the eyes?
- MAc pigment is a loose powder product that can be used as eyeshadow, highlighter, or mixed in with lip gloss, nail polish, lotion, and many other things to create new shimmer/colored products. Most people use it as eyeshadow, and basically it's just a loose powder instead of pressed and it is highly pigmented, which means the color lasts longer, is more vivid, and you need less product to get high-impact color.
- Q: How to manufacture FRP pigments?
- Pigment A finely divided material which contributes to optical and other properties of paint, finishes, and coatings. Pigments are insoluble in the coating material, whereas dyes dissolve in and color the coating. Pigments are mechanically mixed with the coating and are deposited when the coating dries. Their physical properties generally are not changed by incorporation in and deposition from the vehicle. Pigments may be classified according to composition (inorganic or organic) or by source (natural or synthetic). However, the most useful classification is by color (white, transparent, or colored) and by function. Special pigments include anticorrosive, metallic, and luminous pigments. See also Dye; Luminous paint; Paint.

- Melanin (i /?m?l?n?n/; Greek: μ?λα?, black) is a pigment that is ubiquitous in nature, being found in most organisms (spiders are one of the few groups in which it has not been detected). In animals melanin pigments are derivatives of the amino acid tyrosine. The most common form of biological melanin is eumelanin, a brown-black polymer of dihydroxyindole carboxylic acids, and their reduced forms. All melanins are derivatives of polyacetylene. The most common melanin – dopamelanin – is a mixed copolymer of polyacetylene, polyaniline, and polypyrrole. Another common form of melanin is pheomelanin, a red-brown polymer of benzothiazine units largely responsible for red hair and freckles. The presence of melanin in the archaea and bacteria kingdoms is an issue of ongoing debate among researchers in the field. The increased production of melanin in human skin is called melanogenesis. Production of melanin is stimulated by DNA damage induced by UVB-radiation,[1] and it leads to a delayed development of a tan. This melanogenesis-based tan takes more time to develop, but it is long lasting.[2] The photochemical properties of melanin make it an excellent photoprotectant. It absorbs harmful UV-radiation and transforms the energy into harmless heat through a process called ultrafast internal conversion. This property enables melanin to dissipate more than 99.9% of the absorbed UV radiation as heat[3] (see photoprotection). This prevents the indirect DNA damage that is responsible for the formation of malignant melanoma and other skin cancers. Albinism (from Latin albus, white; see extended etymology, also called achromia, achromasia, or achromatosis) is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of an enzyme involved in the production of melanin.
- Q: hi:]i need the right order to apply skin pigments...
- Pigments are usually packaged in a finely milled loose powder form. After cleansing , toning and moisturizing,let the moisturizer absorb in the skin. Apply the skin pigments using a large compact powder brush/kabuki brush in a circular motion on face neck, then apply a second layer in a downward motion. Then use Evian water Mister to set the pigment. For eye pigments, put a thin layer of skin pigment first, then apply the eye pigment using a oval shaped dome brush
- Q: Can someone describe the role of accessory pigments in photosynthesis?
- Accessory Pigments In Plants
- Q: Hi what is pigment?i went on mac cosmetics and they sell all different kinds of stuff called pigment. I want to use it to make lip gloss but is it safe for my lips?please answer soon!
- pigment is just color. the color shown or what makes a color. MAC is GREAT!!!!! its a color used to product a color or the actual color itself. either way....pigment means color.
- Q: what are accessory pigments?
- Accessory pigments are light-absorbing compounds, found in photosynthetic organisms, that work in conjunction with chlorophyll a. They include other forms of this pigment, such as chlorophyll b in green algal and higher plant , while other algae may contain chlorophyll c or d. In addition, there are many non-chlorophyll accessory pigments, such as carotenoids or phycobiliproteins which also absorb light and transfer that light energy to photosystem chlorophyll. Some of these accessory pigments, particularly the carotenoids, also serve to absorb and dissipate excess light energy, or work as antioxidants. The different chlorophyll and non-chlorophyll pigments associated with the photosystems all have different absorption spectra, either because the spectra of the different chlorophyll pigments are modified by their local protein environment, or because the accessory pigments have intrinsic structural differences. The result is that, in vivo a composite absorption spectrum of all these pigments is broadened and flattened such that a wider range of visible and infrared radiation is absorbed by plants and algae. Most photosynthetic organisms do not absorb green light well, thus most remaining light under leaf canopies in forests or under water with abundant plankton is green, a spectral effect called the green window. Organisms such as some cyanobacteria and red algae contain accessory phycobiliproteins that absorb green light reaching these habitats.
