Description of LED Fluorescent:
The degradation of electroluminescent devices depends on frequency of driving current, the luminance level, and temperature; moisture impairs phosphor(Fluorescent Powder) lifetime very noticeably as well.
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.

- pigment is the coloring of your skin and considering your skin gets darker under sunlight im going to say it absorbs light.
- Q: What are MAC eyeshadow pigments? Are they just like regular eyeshadow.. are they used the same way? Has anyone tried them and liked them?
- there just loose eyeshadows, yes they are like regular eyeshadow, i like them but they can be messy
- Q: What are iridescent magnetic effect pigments?
- Iridescent okorder /... (really long explanation)
- Q: I have been looking over the internet and have yet to find the details I need. Such as the function and development of Pigments.
- A pigment is a material that changes the color of light it reflects as the result of selective color absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which the material itself emits light. Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures. You can thank me later.
- Q: how are the pigments in clothes differ from plant pigments?
- Pigments are pigments. They are made of molecules that absorb some colors and reflect others from the visible spectrum of light, which gives everything color. Black pigments absorb everything and reflect nothing, so black is the absence of color and it is why dark clothing are warmer in winter. White pigments reflect everything and absorb nothing, so clothing that is white is cooler in summer. Most plants have more chlorophyll, a green pigment, in them than other pigments, so the plant is overwhelmingly reflecting green back to our eyes and absorbing the red and blue ends of the spectrum. In fall, when the chlorophyll breaks down, we can see the yellow, orange, and red pigments that are also in the leaf for a few weeks. In this way, all pigments are alike. However, perhaps what your teacher is looking for is that the green pigment chlorophyll in plants not only absorbs red and blue wavelengths of light, it also uses that energy to excite electrons from the molecules of chlorophyll and send them through an electron transport chain that enables light energy to be converted to chemical energy and store it in the C-H bonds of glucose, which is made during photosynthesis. Other pigments, whether they be in clothes or other objects such as cars or just about anything else do not do this. Only plant chlorophyll, or the green pigment in plants, converts light energy to chemical energy. That is the one huge difference. Otherwise, like all other pigments, chlorophyll absorbs some wavelengths of light and reflects others, in the case of chlorophyll, green wavelengths of light.
- Q: thinking about the main role of pigments in photosynthesis...? explain how the pigments in colored objects suc?
- photosynthetic pigment or antenna pigment is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis. Green plants have five closely-related photosynthetic pigments (in order of increasing polarity): Carotene - an orange pigment Xanthophyll - a yellow pigment Chlorophyll a - a blue-green pigment Chlorophyll b - a yellow-green pigment Phaeophytin a[1] - a gray-brown pigment Phaeophytin b[1] - a yellow-brown pigment Chlorophyll a is the most common of the six, present in every plant that performs photosynthesis. The reason that there are so many pigments is that each absorbs light more efficiently in a different part of the spectrum. Chlorophyll a absorbs well at a wavelength of about 400-450 nm and at 650-700 nm; chlorophyll b at 450-500 nm and at 600-650 nm. Xanthophyll absorbs well at 400-530 nm. However, none of the pigments absorbs well in the green-yellow region, which is responsible for the abundant green we see in nature.
- Q: what roles do pigments have in energy transfer?
- Pigments okorder /... When a photon of just the right amount of energy strikes an electron resonating in the pigment, the electron can absorb the photon and get promoted to a higher quantum level. The photon must have just the exact amount of energy to boost the electron from its current level to its new level or it cannot be absorbed. If the incoming photon is just right to promote an electron, in that pigment, the newly energized electron resonates along the bonds at the higher energy level where it can pass to the photosynthetic reaction center from the pigment array, to split water and take back an electron. Meanwhile the chlorophyll's electron passes to the electron transport chain to begin oxidative phophorylation.
- Q: what is the difference between light color and pigment colors?
- Check out the links below. They should answer any question about the properties of light. In a nutshell, the color of light is an electromagnetic radiation.that the human eye sees. The rainbow is a visual phenomenon that shows the transmission of those radiant colors. We see them all.. ,orange, yellow, green blue, indigo, violet at one time because they are being filtered through the moisture in the air. Of them all, only the primary colors are true colors.. , green and blue. The others are where the light blends together. Pigments are artificially produced things that bend light in such a way that we see a different color. A pigment reflects the available light, changes it because of its absorption property. Thats why black is both a color and the absence of color. In light, black is the combination of all colors (black absorbs all radiant light) and in pigment the absence of any color.
