LED “Efficiency Droop” Problem Solved

One of the key obstacles to the wider adoption of LED lighting may have just been solved, nearly 15 years after its discovery — the mechanism behind the flaw known as “efficiency droop” has finally been identified, potentially leading the way to new techniques/technologies to address it. Efficiency droop is … [continued]

Stanford Engineers Weld Nanowires with Light

  By Andrew Myers One area of intensive research at the nanoscale is the creation of electrically conductive meshes made of metal nanowires. Promising exceptional electrical throughput, low cost and easy processing, engineers foresee a day when such meshes are common in new generations of touch-screens, video displays, light-emitting diodes, … [continued]

Hybrid Capacitors Provide Long-lasting Energy to LED Lights

Light emitting diodes (LEDs) provide long-life lighting technology that powers flashlights, street signs and medical devices. LEDs have bright output with low input power, making them much more energy efficient than their incandescent predecessors. Hybrid capacitors, a combination of an ultracapacitor and a lithium-ion battery, are an ideal choice for LEDs because the low energy and power of LEDs allows hybrid capacitors to be a longer term energy source than alternative energy storage solutions on the market. Other benefits of LEDs to lighting include little to no required maintenance.
