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: Are carontenoids and anythocyanin accesory pigments.
- Accessory pigments are those , that can not do photosynthesis and manufacture sugar as essential pigment chlorophyll does. But these accessory pigments capture solar energy in the form of photons and then transfer it to chlorophyll molecules / pigments . Thus increasing the power of chlorophyll to do photosynthesis . carontenoids and anythocyanin are accesory pigments. click on the links below to learn more about the accessory pigments - en.wikipedia.org/wiki/Accessory_p... www.ucmp.berkeley.edu/glossary/gl... www.cas.muohio.edu/~meicenrd/BMZ1... Thank you !
- Q: okay so I have always used all the cheap makeup and I am sick of it! I was wondering if mac pigments will give me a lot of color without having to use half of the container. Most eyeshadows look nothing like they are supposed to on me. they are like 100 times lighter. I have seen beautiful things done with the pigments but they look like they could get everywhere really easy. will they give me vibrant color without getting all over?
- Mac okorder it's only $0.99 a for either kind for .06 oz, you just need to use a eye primer for the best color results ( same as mac when using primer see you tube videos on NYX vs MAC pigments for proof). Plus cherryculture has numerous other makeup brands for dirt cheap. Hope this helps. Also all pigments should be applied with a slightly damp brush and a primer for the hugest impact. Used alone they are sheer and end up all over your face. If brush is dampened with no primer used on the eye they work ok but you get a lot of creasing, and it still won't be that dramatic look you are wanting. I realized this after major internet searching and trial and error, because I was upset I paid so much for the HIP pigment and it just wasn't staying put nor was it showing up. So again hope this helps.
- Q: What are accesory pigments and why are they important?
- Accessory pigments, also called, Photosynthetic Pigments or Chloroplast pigments, are pigments which are present within the cell of a Chloroplast used to harvest a greater spectrum of light.y are colored compounds which absorb and transfer light energy to chlorophyll. Pigments are light-absorbing molecules. In addition to chlorophyll,other pigments, principally yellow and orange carotenoids, as well asother forms of chlorophyll, are also present in green plants. These molecules absorb light and then pass the energy to the chlorophyll and accessory pigments, like the carotenoids, enable the plants to use more ofthe light than is trapped by chlorophyll alone.
- Q: I have bought 2 Mac Pigment to use as eyeshadow,I thought it was supposed to be easy to use,turned out it wasn't.My eye looked like I got hit, so messy and the pigment was all over the place. I wonder if i should wet my brush or do u have some kind of tricks before applying it.Any advice would be appreciated.Thanks for helping.
- Mixing okorder /watch?v=tbKmWd_Fl... I believe you can use vaseline for this as well. Also, it sometimes helps to use a sponge applicator, and yes, wetting your brush works as well. Start with a LITTLE. If you get a whole bunch on your brush you're going to make a huge mess.
- Q: what pigment are? give two example
- i need example sentences of pigment.. Thanks.. :)
- Q: what the book says is that they 'harvest additional wavelengths.' i don't know what this means to how its an advantage.. can somone explain?
- Each photon has a particular wavelength, determined by the photon's energy. A pigment such as chlorophyll can only absorb photons in particular wavelength bands, matching the energies of available electron transitions to excited states. For chlorophyll, these bands are in blue and red -- the green color of most leaves is due to the waste light that is not absorbed by chlorophyll, while red and blue photons can be absorbed and used to power photosynthesis. An accessory pigment can absorb a photon that has a wavelength (color) outside of the bands that chlorophyll is able to absorb and can pass some of the absorbed energy on to chlorophyll, getting rid of the excess energy in another form, such as heat. A pigment might be tuned to absorb a photon of yellow light; the absorbed energy, stored in the excited state of an electron, is called an exciton (the photon becomes an exciton, so energy is not created or destroyed). The exciton can be passed to a chlorophyll, but only with the same energy as the red photon that the chlorophyll could normally absorb directly. The excess energy, the difference in energy between the yellow and red photon, must be dissipated in another form. This process allows a plant to harvest photons that would otherwise be unavailable to its photosystems. Consider how this would be an advantage to a plant living on a shaded forest floor, or to a planktonic cyanobacteria floating in the water below other photosynthetic algae, in regions where photosynthetically useful photons are scarce.
- Q: explain how the pigments in colored objects such as clothes differ from plant pigments
- 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: pigment: its color (to our eyes) what color of light it absorbsChl a Chl bCartenoidsany right answers would bbe greatly appreicated thanks soo muchhh
- pigment: .... reflected color to eyes .. what color of light it absorbs Chl a reflects green spectra between the blue and red absorption peaks. Some is absorbed at blue 450nm but most absorbed at red 680 - 700nm. Chl b reflects green spectra between the blue and red absorption peaks with a difference in which peak is stronger. Most is absorbed at blue 470 but also some at blue 430 and red 640 nm. Cartenoids reflect yellow, orange, or red and absorbs blue to blue-green light spectra. Xanthophyll absorbs well at 400-530 nm. Xanthophylls are a common sub class of the carotenoid pigment group. Beta-carotene absorbs most strongly between 400-500 nm.
- Q: I'm onto black-berry.. I wonder what else is available in 98362.
- Pigments from the past came from rocks, minerals, plants, and other natural materials. Those things are all still available. You can take classes at some universities that teach how to make your own paints, or dry pigments. For native American pigments, you have to research which tribe used which colors. To be totally authentic you could visit the tribe of your choice and see if you can learn from them. Sticking to your own zip code will not net you much, usually.
- Q: Why is it important for a plant to have more pigments than just chlorophyll?
- if the plant has more than one color of pigments, it can absorb more spectrums of the visible scale and create food longer, therefore surviving longer
