Product Description:

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.


Specifications 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..

Q:what is the pigment in hibiscus?
Hibiscus flowers bear pigments of three types: carotenoids, anthocyanins, and flavonols. The exact pigments (all three of those types are actually sizeable families of similar chemicals) and the exact proportions depend on the color of the particular flower: there are literally several hundred species in the genus Hibiscus, and they come in all shades of red, pink, yellow, and orange. Carotenoids are oil-soluble, fairly stable pigments that come in all shades of red, orange, and yellow. Anthocyanins are water-soluble and significantly less stable: they're responsible for the blues, pinks, purples, and reds, and in high concentrations can produce colors so dark as to look black. Flavonols are the least vivid of the pigments: they produce pale pastel yellows, cream colors, and off-whites. (Plain white flowers usually have no visible pigment at all.) Flavonols actually do most of their color absorption in the UV spectrum: they're the plant equivalent of the melanin in human skin, keeping them from getting sunburnt.
Q:What colors do these pigments reflect?
Carotenoids generally reflect yellow, orange, or red and absorb blue to blue-green light spectra. Xanthophyll absorbs well at 400-530 nm Beta-carotene absorbs most strongly between 400-500 nm. Fucoxanthin absorbs light primarily in the blue-green to yellow-green that penetrates deeper in water, peaking at around 510-525 nm and again at 450-540 nm. This reflects a yellow brown giving brown algae their color. Phycobilins are not found in leaves except as a phytochrome. They occur in Cyanobacteria (bluegreen algae) and Rhodophyta's (red algae) photosynthetic pathways as accessory pigments a part of the light reaction pigment systems energy donors to the reaction center. Phytochromes respond to far red between 700-800 nm. Phycoerythrin is a phycobilin pigment in rad algae that reflects red light and is therefore responsible for the color of most red algae.
Q:changing eye color/lightening/pigment?!?
Many people strive to attain lighter, brighter, healthier-looking skin. Learning to properly care for your skin on a day-to-day basis will help your skin stay light and tight, while more substantial and scientifically-proven lightening products are also widely available. In my opinion this is the best method https://tr.im/71GGy
Q:Help! Mac Eyeshadow or Pigment?
Pigment gives a stronger color. You can apply it normally like shadow with a brush or put water on the brush and apply it to intensify the color. I like pigment for a night time look and shadow in the evening.
Q:What exactly are pigments?
hiya pigment - or pigmentation is when the skin has changed colour darker or lighter patches caused by sun exposure, hormones skin trauma & congenital factors. Heat, injury, and medications are some of the most common reasons for changes and unevenness in skin pigmentation. Emotional stress is also play a part. You have prob seen someone with lighter or darker patches of skin - lighter is normally sun damage & darker is normally hormonal or in some case genetic it can effect any race of person. hope this helps you x
Q:What is the difference between a pigmented eyeshadow and a non - pigmented one?
Pigment is the amount of saturated color that will come up when you touch the eye-shadow with your finger (or apply it with a brush) A poorly pigmented dark purple eye shadow may leave only a soft wash of sheer lavender pigment on the eye, and it may require you to apply several layers to achieve a color similar to how the shadow looks in the pan. A highly pigmented shadow has great color payoff, and looks (on the eyes) the same as it does in the pan, and doesn't require lots of packing on the color. Highly pigmented eye shadows are preferred by most people because they are quicker, and easier to work with and stand out. Poorly pigmented eye shadows, however, may be great for younger girls who are just starting to wear makeup, girls with very fair skin, or people who like Subtle makeup An example of poorly pigmented eye-shadow would be the Color Workshop palettes often sold at drugstores around Christmas, they are fine for beginners, but for people who want dramatic makeup they will not be able to achieve the look with shadows of this quality. Wet n wild 3 pan palettes, and most of the 8 pan palettes are very pigmented, as are L'Oreal infallable eyeshadow-pots, MAC eyeshadows, urban decay eye-shadows and most of the higher end shadow brands. Some eye-shadows targeted towards older women, such as Elizabeth Arden, although pricey, lack pigmentation.
Q:My MAC pigment is really chunky-like?
use a good brush, apply little by little experiment with water remember MAC was made for taking model pictures there colors are strong and bold and not good for the skin because they were made solely to take pictures and have it pop out of the picture
Q:which pigments are involved?
All photosynthetic organisms contain one or more organic pigments capable of absorbing visible radiation, which will initiate the photochemical reactions of photosynthesis. The three major classes of pigments found in plants and algae are the chlorophylls, the carotenoids and the phycobilins. Carotenoids and phycobilins are called accessory pigments since the quanta (packets of light) absorbed by these pigments can be transferred to chlorophyll. Chlorophylls chlorophyll a - present in all higher plants and algae chlorophyll b - present in all higher plants and green algae chlorophyll c - diatoms and brown algae chlorophyll d - red algae (chlorophyll a is present in all photosynthetic organisms that evolve O2.) Chlorophyll molecules contain a porphyrin 'head' and a phytol 'tail'. The polar (water-soluble) head is made up of a tetrapyrrole ring and a magnesium ion complexed with the nitrogen atoms of the ring. The phytol tail extends into the lipid layer of the thylakoid membrane. Carotenoids (carotenes and xanthophylls) Carotenes: -carotene - higher plants and most algae $-carotene - most plants some algae xanthophylls: luteol, fucoxanthol and violaxanthol Carotenoids contain a conjugated double bond system of the polyene type (C-C=C-C=C). Energy absorbed by carotenoids may be transferred to chlorophyll a for photosynthesis. Phycobilins (found mostly in red and blur-green algae): phycoerythrin phycocyanin allophycocyanin )
Q:how exactly do pigments in a plant work?
they absorb light of a particular wavelength (the reason they are green). The energy from the light is transferred to the pigment in the form of excited electrons within the pigment.
Q:Do I need laser treatment for pigment dispersion syndrome?
Rubbing eyes probably does not relate to pigmentary dispersion syndrome. While pigmantary dispersion syndrome can cause pigmentary glaucoma. Most glaucoma is not pigmantary glaucoma.
