LED product and lighting maker Lumileds LLC of San Jose, CA, USA claims to be first to demonstrate that rich deep red light (615nm dominant wavelength corresponding with 635nm peak) can be produced with indium gallium nitride (InGaN) LEDs, achieving a wall-plug efficiency of 7.5% at a current density of 10A/cm2. The firm says that its breakthroughs address the challenges associated with high indium concentrations, including spectral peak shifts and broadening with current density...
