Industrial and Commercial LED Lighting Industry 2017: Global Market Current Scenario 2025
When an electric current is passed through an LED, light is emitted. An LED is a semiconductor device, with output ranging from blue-violet (about 400 nanometer (nm)) to red (about 700 nm). Some LEDs are called infrared emitting diodes (IRED), emitting infrared (IR) energy, which is greater than or equal to 830 nm. An LED consists of two elements of processed material, namely, N-type semiconductors and P-type semiconductors, which are placed in direct contact to form a region called P-N...
