Light-emitting diode (LED) technology is an emerging nonthermal food processing technique that utilizes light energy with wavelengths ranging from 200 to 780 nm. Inactivation of bacteria, viruses, and fungi in water by LED treatment has been studied extensively. LED technology has also shown antimicr...
A light emitting diode apparatus includes a substrate, a first conductive type semiconductor layer, a second conductive type semiconductor layer, a mesa, a lower insulating layer, a first pad and a second pad. The substrate has a first surface and a second surface opposite to the first surface...
1. Introduction Light emitting diodes (LEDs) were developed around 50 years ago, initially for application as indicators and low resolution monochromatic displays.[1] With improvements in both material (including demonstration of blue-green devices using III-N materials in the early 1990s),[2]fabric...
Metal halide perovskites have shown promising optoelectronic properties suitable for light-emitting applications. The development of perovskite light-emitting diodes (PeLEDs) has progressed rapidly over the past several years, reaching high external quan
Micro-light-emitting diodes (μ-LEDs) are regarded as the cornerstone of next-generation display technology to meet the personalised demands of advanced applications, such as mobile phones, wearable watches, virtual/augmented reality, micro-projectors an
Light-Emitting Diode (LED): Function: Converts electrical energy into light energy when forward biased. Operation: When a forward voltage is applied across the LED, it allows current to flow, causing electrons to recombine with electron holes in the semiconductor material, emitting photons (light)...
Organic Light Emitting Diode (OLED) is an emerging technology as one of the strong candidates for next generation solid state lighting with various advantages such as thin flat shape, no UV emission and environmental benefits. At this moment, OLED still has a lot of issues to be solved before...

The high-radiance Burrus-type (surface-emitting) LED is well suited for application in systems of low to medium bandwidth (<50 MHz). The power that can be coupled from an LED into a fiber is proportional to the number of modes the fiber can propagate, that is, to its core area times...
