Our annual One Bright Issue covers the latest in LED and display technologies. For my part, I thought I would write about a couple of LED products that I saw at Electronica late last year and ...

Gaggione is highlighting adjustable beam optics for its Sirius range of LED optics. The zoom function is to allow switching between narrow and wide light distributions. For Sirius, there are two ...

From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing ...

There has been a lot of discussion about the issue of measuring the lifetime of solid-state lighting. Industry watchers say standards in this area are probably still in the future. Nevertheless, there ...

A new LED design uses a built-in nanoscale metasurface to emit circularly polarized light directly, eliminating bulky optics ...

The LED, or light-emitting diode, itself is very unlikely to fail, and if it does, it goes out slowly over the years. Instead, it's the other electrical bits in LED bulbs that fail and cut off the ...

Radio frequency interference (RFI) to frequencies in the AM and shortwave broadcast bands has been on the increase in the last two decades, due primarily to switch-mode power supplies being used for ...

Energy efficiency often translates directly into financial benefits. Lighting systems that consume less electricity can substantially reduce monthly utility expenses. Over time, these savings ...
