This is the simple version of a white LED lamp that can be directly powered from mains. It can give ample light even for reading purpose. Capacitor Cx along with diodes D1 through D4 forms the AC step ...

LED technology is opening thedoor to a variety of high-power-illumination applications. The circuit in Figure 1 can let you know when ac power is available. To drive a power LED from the ac line ...

The first implementations of AC-direct LED systems, however, gave their designers tricky design problems to solve, and severely limited their freedom to optimise operational features and the luminaire ...

Not only that, drivers use space, restricting lighting designers’ creativity. Now Illumis Lights has solved both problems with its revolutionary AC electrical system. Our new range of high-voltage AC ...

Compared to the conventional inefficient incandescent and fluorescent lighting technologies, LED light bulbs can, in principle, operate at an efficiency level of 100%. The current LED lighting ...

Seoul Semiconductor, a leading global innovator of LED products and technology, has developed the industry’s smallest 100V / 24W LED driver for Japan ...

Teardowns of cheap electronic devices can produce results that are interesting, horrifying, or both, especially when mains power is involved. [bigclivedotcom] gave a minimalist LED lamp his reverse… ...
