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:

Phosphor layers provide most of the light produced by fluorescent lamps, and are also used to improve the balance of light produced by metal halide lamps. Various neon signs use phosphor layers to produce different colors of light. Electroluminescent displays found, for example, in aircraft instrument panels, use a phosphor layer to produce glare-free illumination or as numeric and graphic display devices. White LED lamps consist of a blue or ultra-violet emitter with a phosphor coating that emits at longer wavelengths, giving a full spectrum of visible light.


Specifications of LED Fluorescent:

Appearance: Yellow crystalline powder

Chemical composition: Rare earth aluminate

Physical stability: waterproof and heatproof. No any changes under -50°C to 300°C in the air.

Chemical stability: under 200°C, brightness >90%; within 1000 hours after encapsulation, brightness decay

Safety: Conform to the RoHS {EU (Restriction of Hazardous Substances)} and all security standards. Non-poisonous, non- radioactivity and do no harm to human and environment.

Q:What are pigments?
technically, pigment is a colored mineral of some kind that is ground as fine as possible. (i.e., cobalt is blue, iron produces reds, etc.) Pigment is the same whether it's in cosmetics, ceramics, or in paint. However, modern chemicals may also have the effect of coloring the ingredients of cosmetics, but that would make them a colorant, not a pigment.
Q:What is the importance of the accessory pigments?
Q:Is gel food coloring a pigment or a dye?
Dyes contain pigments, my friend. What is a pigment? They are like little beads. Very very tiny beads of the same color. Then if you spread these out, they give the thing a color. For example, the little green beads in leaves give it a green color. Pigment in our hair gives it a blonde/auburn/brown/black color. What is a dye? A dye is a liquid made up of water and pigments. The pigments are dissolved in water (well not really dissolve just that you cant see the beads) so that it's easier for us to use it. Everything that has a color is made up of pigments. So, gel food coloring is a thicker version of a dye that contains pigments.
Q:compare and contrast the different pigments involved in photosynthesis?
Q:Can someone describe the role of accessory pigments in photosynthesis?
help the primary pigments gather sunlight and adds color to the plant
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: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:Why do algae contain pigments other than just chlorophyll?
they stay underwater...the water swollows easy in a definite sequence, so the deeper they stay the greater distinctive is the easy and that they elect different pigments than landplants.
Q:What is pigment?????
Pigment is colour. :]
Q:M.A.C pigments question!?
Buying okorder.com/... Good luck dear! If all else fails, I suggest going on specktra.net and asking on there. It's a MAC and make-up community forum and they're extremely helpful and informative when it comes to anything MAC!
