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:

 The decay time is the emission parameter that indicates temperature. Because the illumination and detection optics can be situated remotely, the method may be used for moving surfaces such as high speed motor surfaces. Also, phosphor may be applied to the end of an optical fiber as an optical analog of a thermocouple.

Q:What eyeshadow brand is the most pigmented?
Highly Pigmented Eyeshadow
Q:What does pigmented mean?
Pigment means color. So highly pigmented would mean lots of color.
Q:What does the word pigment mean?
meant to be a pig. :)
Q:Separation of plant pigments?
Separation of plant pigments using chromatography. Paper chromatography is a useful technique in the separation and identification of different plant pigments. In this technique, the mixture containing the pigments to be separated is first applied as a spot or a line to the paper about 1.5 cm from the bottom edge of the paper. The paper is then placed in a container with the tip of the paper touching the solvent. Solvent is absorbed by the chromatographic paper and moved up the paper by capillary action. As the solvent crosses the area containing plant pigment extract, the pigments dissolve in and move with the solvent. The solvent carries the dissolved pigments as it moves up the paper. The pigments are carried along at different rates because they are not equally soluble. Therefore, the less soluble pigments will move slower up the paper than the more soluble pigments. This is known as developing a chromatogram.
Q:Give the function of the observed pigments -?
Q:what is pigment ink???????
Some printers use only pigmented ink. Others use dye based and then some use a combination of both. Dye based ink is basically water based with a dye added to it. Pigmented ink has a solvent base with dye added. Pigment ink and dye based ink have both advantages and disadvantages. Dye based ink have better colors but pigment are more water and fade resistant. Dye based inks are therefore better for photos. I have a printer that has 4 dye based inks and a black pigment ink. Mine uses the dye based black and colours for pictures and the pigmented black is used for text. So the answer is yes. Pigmented ink is used in some regular printers.
Q:What is the difference between a pigmented eyeshadow and a non - pigmented one?
A pigmented eyeshadow means that it comes out on your eyes the color it is in the tray or palette for example you buy a black eyeshadow and when you swatch it or apply it to your eyes it looks dark gray or just completely different from how it appears to be
Q:Why is it important for a plant to have more pigments than just chlorophyll?
If the plant only has chlorophyll, it is only able to absorb and use the wavelengths of light that correspond to chlorophyll, which is really limiting. Having other pigments allows it to use more wavelengths of light, which is more efficient.
Q:7th grade biology/botany. Leaves + color Pigments + HELP!!!!! + Please!!!?
1. Changes in pigment compsition is the primary reason for the changes in the colour observed during different developmental stages of leaves. 2. Each pigment has the property of absorbing light rays of certain wave lengths and reflecting rays of certain wave length. This is called chromatic property of the pigment. For example Chlorophyll absorbs all wavelengths and reflects green wave lengths. Hence it appears green in colour. Therefore the colour is in the light rays and not in the pigment. 3.Reds= Phycoerythrin; Yellows= Xanthophylls; Purples= Anthocyanins; Browns= different combinations of red and yellow pigments; greens= Chlorophylls; Blue= Phycocyanins. 4. Yes 5. The process of leaf fall is called Abcission. Leaf os an organ of definitive growth. It grows to its maximum size and becomes scenescent. Once scenescence sts in, all cellular materials that can be used elsewhere are translocated to other growing parts and the leaf becomes yellow. The water supply to the leaf is cut off. The phloem also becomes non-functional. At this stage a special layer called Abcission layer is formed at the base of leaf near the point of atachment to the stem. The abcission layer produces cork cells which plug the region. The layers of cells above the cork layer become deprived of water and food and die forming Separation layer. At this stage the leaf is attached to the base only by the xykem cells. By its shere weight the leaf breaks and falls. The most important point about abcission is that the exposed part of the leaf base is covered by cork layer which is impervious to entry of pathogens! Refer to any Plant Anatomy book for a diagram to show the longitudinal section of the abcission layer.
Q:In photosynthesis whats the difference between primary and accesory pigments?
Primary pigments are molecules that convert light energy to chemical energy directly; chlorophyll is the primary pigment in all photosynthetic organisms. Accessory pigments are molecules that absorb photons which are not captured by chlorophyll. The presence of accessory pigments (found in the thylakoid membranes of plants) allows phototrophs (plants, algae, and cyanobacteria) to capture energy from the sun that would otherwise go to waste. The two most common types of accessory pigments are carotenoids and phycobilins. Some examples of carotenoids in common plants are: beta-carotein (carrot orange), lutein (marigold yellow), and lycopene (tomato red). Phycobilins are found only in red algae or cyanobacteria. The two most common phycobilins are: phycoerythrin (red), and phycocyanin (blue). The presence of accessory pigments in plants is masked by the presence of chlorophyll during the Spring and Summer seasons; that's why leaves are green most of the time. The color change from green to red, orange, or yellow that we observed during the Fall season is caused by the absence of chlorophyll; the accessory pigments are always present until the leaves fall as the trees go into dormant mode.
