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 ...

I remember seeing a very simple night light type circuit with a few caps, diodes and LEDs. It was a bit more complicated than what you describe but it was a very simple circuit.<BR><BR>The ...

Seoul Semiconductor, a leading global innovator of LED products and technology, announces a comprehensive series of AC LED modules that use the compan ...

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 ...

ANSAN, South Korea--(BUSINESS WIRE)--Seoul Semiconductor, a global innovator of LED products and technology, has demonstrated a 277V AC lighting module using its NanoDriver Series LED driver that ...

Fairchild introduced the new FL77944, a family of LED Direct AC Drives that manufacturers can use to easily scale power and create smart and scalable LED-based lighting.

We've talked about how AC circuits change voltage, but let's take a deeper look.

Patel founded Ferndale-based Midwest Circuits, now a municipal LED street-lighting manufacturer, in 1995 with another sector in mind: automobiles.
