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: can the pigment know as Chinese purple form a matter wave in certain circumstances?
- Scientists explore atomic mysteries of ancient pigment LOS ALAMOS, N.M., Nov. 18, 2004 -- University of California scientists from the National High Magnetic Field Laboratory, Pulsed Field Facility at Los Alamos National Laboratory, working with colleagues from Tokyo Metropolitan University, the University of Buenos Aires in Argentina, the National Institute of Chemical Physics and Biophysics in Estonia, the National High Magnetic Field Laboratory in Tallahassee, Florida and the University of Tokyo, have discovered an ideal candidate for Bose-Einstein condensation in the ancient Chinese pigment, Han Purple. In research featured recently on the cover of Physical Review Letters, the team describes how the application of a strong magnetic field to Han Purple (BaCuSi2O6) creates a gas of bosonic spin triplet excitations. The field acts as a chemical potential causing the weakly interacting bosonic gas to undergo Bose-Einstein condensation (BEC) when the temperature is reduced to minus 453 degrees Fahrenheit, six orders of magnitude higher than the temperature normally required for BEC in atomic gases.
- Q: There was a question, not to long ago, that asked are L'oreal HIP pigments good? What are pigments?
- Pigments are tones. Like if you have a base color of white and add a light pink and as you go down it gets darker. There would be several pigments of pink tones.
- Q: Explain light activation of pigments (absorption of light by pigments)?
- A pigment is a substance that imparts color by absorbing some frequencies of visible light but not others. For instance, there are a lot of substances that absorb ultraviolet light into the visible spectrum, in other words they also absorb plain violet light. Since they absorb violet light but reflect back the rest of light, they appear yellow. Purple pigments, on the other hand, are quite rare because they absorb purple light (which has the highest energy of visible light) and reflect back everything else. When anything absorbs a photon of electromagnetic radiation (light, x-rays, ultraviolet, infrared, microwaves, gamma rays, radio waves), it is activated which means that it takes the energy of the photon and goes to an energy state that is higher by the same amount of energy that was in the photon. At the molecular level, energy is quantized, meaning its restricted to particular states. For instance, vibrational energy corresponds to infrared light: there are only certain ways, called modes, that a molecule can vibrate in, if it can't vibrate in an appropriate mode, it can't absorb the infrared radiation that corresponds to being promoted to that mode. That's why substances can be transparent. At the higher energy state, the substance might be able to participate in chemical reactions that it would not be able to participate in in a lower state. That's usually what is meant by light activation. So a pigment that absorbs visible or UV light might become activated and react with something or react in ways that it wouldn't be able to in the dark.
- Q: what pigment are? give two example
- pigments found in plants, vegetables and fruits, make them look colorful. pigments found in animal skins, givie us colorful animal skins with variety of shades. Plant pigment Chlorophyll makes plant leaves look green. Plant pigment Carotenoid makes fruits and vegetables look orange, yellow, red. Plant pigment Phycobilin makes plants look bluish green or red.
- Q: whats it for? lol
- itz for ur beautifing ur skin.
- Q: a question on my photosynthesis test review...=_=
- How Pigments Work
- Q: I got this question from my A2 Biology but I can't find the answer. Does anybody know?
- Color. Chlorophyll a is light green. The accessory pigments, chlorophyll b is olive green, the xanthophylls are yellow/brown, and the carotenes are red.
- Q: how to prepare coloured pigments?
- Chemically, pigments fall into a number of large groups, but these are often arbitrarily divided into two major groups. The first group comprises pigments that contain nitrogen; it includes hemoglobins, chlorophylls, bile pigments, and dark-colored pigments called melanin, widespread in many animal groups and the chemical that is responsible for variations in the color of human skin. Related to melanins are the indigoids, of which the well known plant pigment indigo is an example. Riboflavin, which is also known as vitamin B12, is one of a number of pale yellow to green pigments that are produced by several plant groups. The second group is formed of pigments without nitrogen. Carotenoids are members of this group, as are the important plant pigments called flavonoids. In leaves, flavonoids selectively admit light wavelengths that are important to photosynthesis, while blocking out ultraviolet light, which is destructive to cell nuclei and proteins. Flavonoids are also important in flower color, in particular providing red and blue pigments. Bright fall colors are produced by the conversion of colorless flavonoids, called flavonols, into colored forms, called anthocyanins. Quinones provide many yellow, red, and orange pigments, including several useful dyes derived from insects that feed on plants containing the quinones. Cochineal, for example, is a red pigment obtained from the fat cells of scale insects that feed on cactus plants.
- Q: As in like makeup pigments??????
- they are small red dots.. and i know this bcuz i have a disease called shambergs disease where you get small little pigments on your legs and they look like bruises.. the doctor calls them red ink dots but this is a treatable condition.. and i think, by the information you gave on your question, that you have these on your face.. so you should go to your doctor.. and they can prescribe you with an antibiotic that will treat your condition.. Goodluck and i hope this helped you find whatever it was you were looking for. *love always, Brit
- Q: Pleaseeeeee answer A.S.A.P Pleaseeee! Are pigments haram?
- Most pigments for dyes and paints come from plants or minerals. What exactly do you need? The second part of your question about haram, needs some explanation, too.
