Light-emitting diode of Cambridge, opt towards a multi-layer structure, in order to reduce (crystal) lattice mismatch and different thermal expansion ratios, in order to avoid cracking of the LED chip at high temperatures (e.g. during manufacturing), reduce heat generation and increase luminous efficiency. Epitaxy (or patterned sapphire) can be carried out with nanoimprint lithography. Even though white light can be created using individual red, green and blue LEDs, perhaps using a single SMD (Surface Mount Device) or through-hole RGB LED, this setup results in poor color rendering or CRI, due to the fact that virtually only 3 wavelengths of light are being
LED tattoo LED tattoo A light-emitting diode tattoo is a type of body modification similar to a tattoo, but specifically involves implantation of technologically based materials versus traditional ink injection into the layers of the skin. LED tattoos are accomplished by a combination of silicon-silk technology and a miniature lighting device known as a light-emitting diode. While there is potential for many applications in the medical, commercial and personal domains, the technology is still in the development stage. Once the ability is attained to condense the parts of a LED to a small enough level, it will be possible for the tattoos
