Light-emitting diodes (LEDs) are everywhere in modern life, from smartphones to home lighting. But today's LEDs have a major limitation: when you try to make them brighter by increasing their power, ...
LEDs with low polarization in a direction similar to standard LEDs show greater efficiency at higher power by resisting 'efficiency droop', a new study shows. The findings open the door to a new ...
From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing so in a cost-effective and efficient way, however, is often a formidable ...
The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found ...
Energy-efficient LED bulbs are becoming more and more popular each day. They use light-emitting diodes (LEDs) to produce light. Compared to traditional incandescent bulbs, LED bulbs use less energy, ...
This design idea describes a high efficiency 14 W LED driver power supply using TinySwitch-III. This design features high ambient temperature operation, hysteretic over-temperature shutdown protection ...
This design example report is a high efficiency, 3.6 W isolated LED driver employing LinkSwitch™-II LNK605DG. It operates at an input voltage ranging from 90 VAC to 265 VAC and delivers an output ...
