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 to LED Communication LED to LED Communication LED (Light-emitting diode) to LED communication, also known as “Mobile Device Light Communications” are sundry techniques which repurpose mobile computer devices, including mobile telephones, to communicate with other devices, using visual or infrared light. “Mobile device light communication” differs from Visual Light Communication as “mobile device light communication” transmits data at speeds thousands of times slower than Li-fi. “Mobile Device Light Communication” takes various forms: A color sensor, or an ambient light sensor, or a reverse biased LED can receive flashes from the mobile device, and send flashes back to the infrared light sensor on the
