Lots of compounds have been used in LEDs Many of these are based on III-V semiconductors using elements from group 13 and 15, such as gallium nitride, indium phosphide, gallium arsenide and "mixed" nitrides InGaN The simple compounds produce light of a particular wavelength, often coatings of phosphors are used to produce extra colors.
Coloured strip lights commonly use light-emitting diodes (LEDs), which can incorporate various elements for their color output. For example, red, green, and blue LEDs typically use gallium arsenide (GaAs) and gallium phosphide (GaP) to produce red and green light, while blue LEDs often utilize indium gallium nitride (InGaN). By combining these colors, strip lights can create a wide spectrum of colors through additive color mixing.
Direct band gap semiconductors are used in light-emitting diodes (LEDs) because they allow for efficient photon emission when electrons recombine with holes. In these materials, the transition from the conduction band to the valence band occurs at the same momentum, enabling the direct release of energy in the form of light. This efficiency in light production is crucial for applications in displays and lighting. Examples of direct band gap semiconductors include gallium arsenide (GaAs) and indium gallium nitride (InGaN).
More than fifty years after the first functional laser was invented, the blue lasers are the preferred type of lasers for data storage (the blue-ray disks). This is mainly due to their relatively short wavelengths, which means that in case of imaging applications and data storage, they allow for a greater amount of information to be written and read. Also, the short wavelength allows for the strong focusing of laser beam and a very fine structure of the written data. Blue laser has mostly replaced the use of red laser in the area of data storage. At the beginning, the first types of blue lasers had many disadvantages. Initially, they were only gas lasers, which needed high currents and produced a huge amount of heat, therefore needing strong cooling. After that, the first types of semiconductor blue lasers (or blue laser diodes) had a very short life (several hundred hours at the most), even if they worked at a very low temperature (needing almost absolute zero values - 00K - to work properly). But further development solved all these issues. While the red and infrared lasers are usually based on GaAs (gallium arsenide), in case of blue lasers, the InGaN (indium gallium nitride, which has a violet color) and GaN (gallium nitride, which has a true-blue color) based ones are preferred . The ZnSe (zinc selenide) based laser was gradually excluded from research, because of its high resistivity, high energy consumption and very small efficiency. The most efficient technology of building blue-lasers is using InGaN quantum wells to form the active medium.
LED development began with infrared and red devices made with gallium arsenide. Advances in materials science have made possible the production of devices with ever-shorter wavelengths, producing light in a variety of colors. LEDs are usually built on an n-type substrate, with an electrode attached to the p-type layer deposited on its surface. P-type substrates, while less common, occur as well. Many commercial LEDs, especially GaN/InGaN, also use sapphire substrate. There are two ways of producing high intensity white-light using LEDs. One is to use individual LEDs that emit three primary colors � red, green, and blue, and then mix all the colors to produce white light. The other is to use a phosphor material to convert monochromatic light from a blue or UV LED to broad-spectrum white light, much in the same way a fluorescent light bulb works.

Light Emitting Diodes, commonly called LED's, do dozens of different jobs and are found in all kinds of devices. Among other things, they form the numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on. Collected together, they can form images on a jumbo TV screen or illuminate a traffic light. :)Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescents, they don't have a filament that will burn out, and they don't get especially hot. They are illuminated solely by the movement of electrons in a material, and they last just as long as a standard transistor. Hope this helped.That talks only about usage, which is all well and good but totally fails to answer the original question of how. Also incandescents operate "solely by the movement of electrons in a material", so that is not really a difference; the difference is in the way those electrons move.LEDs are ordinary semiconductor diodes, except that they are made of different semiconductors than silicon or germanium. Semiconductors composed of multiple elements that by themselves are not semiconductors (e.g. Aluminum gallium indium phosphide = AlGaInP for red, Indium gallium nitride/Gallium(III) nitride = InGaN/GaN for green, Indium gallium nitride = InGaN for blue). Such semiconductors are different from silicon and germanium in 2 ways:larger bandgap between conduction and valence energy bandstransparency to visible light; both silicon and germanium are opaqueThe larger bandgap of these semiconductors means that when electrons and holes combine at the junction they release enough energy to produce photons of light, not just phonons which only vibrate the crystal atoms and cause heating as in silicon and germanium with their smaller bandgap. This larger bandgap also means that the forward bias voltage is larger (between ~1V to ~5V depending on material vs. 0.7V for silicon or 0.2V for germanium).The transparency of these semiconductors allows the photons once generated to escape from the material and be seen, instead of being immediately absorbed as they would in an opaque material and cause heating only.Going back to the difference in operation between incandescents and LEDs:the movement of electrons through the filament of an incandescent light bulb is a phenomenon explained in classical physics, this movement is continuous and causes resistance heating making the filament hot enough to glowthe movement of electrons (and holes) at the junction in an LED is a phenomenon explained in quantum mechanics, this movement is a sudden jump between energy levels in atoms and directly produces light photons
From Wikipedia:LED:A light-emitting diode (LED) (pronounced /ˌɛliːˈdiː/[1], or just /lɛd/), is an electronic light source. The LED was discovered in the early 20th century, and introduced as a practical electronic component in 1962. All early devices emitted low-intensity red light, but modern LEDs are available across the visible, ultraviolet and infra red wavelengths, with very high brightness.Physics:Like a normal diode, the LED consists of a chip of semiconducting material impregnated, or doped, with impurities to create a p-n junction. As in other diodes, current flows easily from the p-side, or anode, to the n-side, or cathode, but not in the reverse direction. Charge-carriers-electrons and holes-flow into the junction from electrodes with different voltages. When an electron meets a hole, it falls into a lower energy level, and releases energy in the form of a photon. The wavelength of the light emitted, and therefore its color, depends on the band gap energy of the materials forming the p-n junction. In silicon or germanium diodes, the electrons and holes recombine by a non-radiative transition which produces no optical emission, because these are indirect band gap materials. The materials used for the LED have a direct band gap with energies corresponding to near-infrared, visible or near-ultraviolet light. LED development began with infrared and red devices made with gallium arsenide. Advances in materials science have made possible the production of devices with ever-shorter wavelengths, producing light in a variety of colors. LEDs are usually built on an n-type substrate, with an electrode attached to the p-type layer deposited on its surface. P-type substrates, while less common, occur as well. Many commercial LEDs, especially GaN/InGaN, also use sapphire substrate. Most materials used for LED production have very high refractive indices. This means that much light will be reflected back in to the material at the material/air surface interface. Therefore Light extraction in LEDs is an important aspect of LED production, subject to much research and development.
