Optimised 650nm Silicon avalanche LED

University of South Africa
Overview of innovation

The invention provides a silicon pn-based device with different dopant and impurity implanted concentrations stra­tegically placed in the device, the pn junction being reverse biased, such that the 650 nm optical emission is stimulated and enhanced.

The Light-Emitting Diode (LED) Grow Lights Market is expected to grow by USD 3.37 billion during 2021-2026, at a CAGR of over 22.14% during the forecast period. One of the main factors boosting market growth is the expansion of indoor farming. Changes in average temperatures, rainfall, and heat waves are just a few of the ways that climate change impacts agricultural land and crop productivity.
