Product Description:

Description of LED Fluorescent:

Separate the powder in the epoxy glue or silica gel uniformly, after deaeration, dot the powder on the CMOS chip, the LED encapsulation will be finished after solidification, etc. It also can be used after mixing with other phosphor (such as red and green powder) in certain proportion to get your required color temperature or rendering index.

Festures of LED Fluorescent:

The powder is a kind of yellow phosphor for LED encapsulation use with the characteristics of high brightness,good stability and no harm to human and environment, which is fired through special manufacturing techniques. This kind of powder is quite applicable to the encapsulation of high color rendering white LED or other lighting appliances.

Specifications 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:Mac Eye Pigments?
The pigments are purer colors that are MUCH more intense and longer lasting. I've got it in two colors. It's great.

Q:whats pigment?
n biology, a pigment or biochrome[citation needed] is any material resulting in color of plant or animal cells, which is the result of selective color absorption. Many biological structures, such as skin, eyes, fur and hair contain pigments (such as melanin) in specialized cells called chromatophores. Plant pigments include a variety of different kinds of molecules, including porphyrins, carotenoids, and anthocyanins. Chlorophyll is the primary pigment in plants; it is a porphyrin that absorbs red and blue wavelengths of light while reflecting green. Carotenoids are red, orange, or yellow tetraterpenoids. Anthocyanins (literally flower blue) are water-soluble flavonoid pigments that appear red to blue, according to pH. They occur in all tissues of higher plants, providing color in leaves, stems, roots, flowers, and fruits, though not always in sufficient quantities to be noticeable.Betalains are red or yellow pigments. Like anthocyanins they are water-soluble, but unlike anthocyanins they are indole-derived compounds synthesized from tyrosine. For more info visit : en.wikipedia.org/wiki/Biological_...
Q:Losing pigment in eyes?
I'm going thru the same thing, I have been to see my eye dr every 6 months to find out about pigment loss and I am losing my pigment at a fast rate 4 times worse than 6 mths ago. they are calling in the specialists about it, so YES worry!!!
Q:What are the accessory pigments and what are their functions?
Accessory pigments are light-absorbing compounds, found in photosynthetic organisms, that work in conjuction with chlorophyll a. They include other forms of this pigment, such as chlorophyll b in green algal and higher plant antennae, 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 chlorophylls. Some of these accessory pigments, particularly the carotenoids, also serve to absorb and dissipate excess light energy, or work as antioxidants.
Q:What pigments take part in photosynthesis?
There are three basic classes of pigments. Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. This is the fundamental process by which chlorophyll captures the energy of sunlight. There are several kinds of chlorophyll, the most important being chlorophyll a. This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll a. A second kind of chlorophyll is chlorophyll b, which occurs only in green algae and in the plants. A third form of chlorophyll which is common is (not surprisingly) called chlorophyll c, and is found only in the photosynthetic members of the Chromista as well as the dinoflagellates. The differences between the chlorophylls of these major groups was one of the first clues that they were not as closely related as previously thought.....
Q:does photosythesis requier pigment moulecuels?
Photosynthesis requires Chlorophyll, which is composed of a mixture of pigments like chlorophyll a, chlorophyll b and xanthophyll. These pigments allow certain wavelengths of light to be used for photolysis, a required stage of the photosynthetic process.
Q:Are pigments the same as tannins?
Yes, tannins are pigments but they aren't really the main plant pigment. Plant pigments usually refer to photosynthetic pigments (chlorophyll, carotenoids, etc.). These photosynthetic pigments give the leaves their green color (or yellow/orange in the fall). Tannins are non-photosynthetic phytochemical (involved in plant metabolism and internal functioning), but they are also a pigment. Tannins (and lignins) are brown. This is was gives dead leaves and wood their color. Tannins also leach out of the leaves when soaked in water (same process as brewing a cup of tea). So tannins are pigments when they leach out of leaves and stain water (or other things) brown, but they are not photosynthetic plant pigments. In other words, it depends on what context you are calling a tannin a pigment. In a live plant they are not a pigment (judgment call here). In a dead leaf or when they leach out of a leaf they are a pigment.
Q:What are Candle Pigments or Candle Coloring Powders ? And What are Candle Liquid Dyes ?
Pigments are generally used for overdipping or decorating candles. Pigments do not fade and do not migrate/bleed, but pigments will clog wicks if used to color solid-colored candles. Pigment flakes are clean and easy to use and give vivid and brilliant colors. They are safe for the candlemaker and for the candlemaker’s customers. The pigment flakes comply with OSHA, TSCA and EN 071 (part 3) legislation. Pigments are insoluble in the medium they are coloring. Pigments, therefore, are not soluble in wax. They color the wax by dispersion. This means that pigments have to be distributed evenly throughout the wax, or dispersed in the wax, in order to color it (versus dyes which are soluble in wax and become a part of the wax to color it). Mixing, therefore, is very important. Usage and Dosage Instructions Dissolve pigments flakes in your wax formulation at approximately 185F - 85C. It is recommended to pre-disperse the required amount of color (see dosage chart) in a small amount of the dipping wax in a ratio of 1:5 color to wax. This should be done at 185F - 85C, using an electric mixer will disperse the color more quickly. Once the pigment is well dispersed, add it to the remaining dipping wax. Stir the dipping wax well before starting production and after each production break. Overdipping Dosage 2 dips : 1% by weight of wax formulation 1 dip : 1.5% by weight of wax formulation For color consistency, always add the same amount of color to your dipping wax. Use a scale to weigh the components of your dipping formulation. Always dip candles at the same temperature, temperature variations will result in color deviations. Too hot a dipping wax will make the shade of color on the candle appear lighter. Too cold a dipping wax will make the shade of color on the candle appear darker. Any variations in the overdipping wax used may result in a change of color on your finished candle. PROPER MIXING IS NECESSARY TO ACHIEVE UNIFORM DISPERSION OF PIGMENTS
