This presentation was originally given by Andrew Smith, product manager, LED Lighting at Power Integrations for EDN’s May 2011 live LED event in San Jose. Consumers often see LED lamp failures. If you ...

Featuring a novel distortion-cancelling input-current shaping (ICS) circuit, the HVLED007 AC/DC LED driver from STMicroelectronics enables energy-saving solid-state luminaires to comply with ...

Guest columnist Naoyuki Kobayashi, senior product manager at Murata says that one problem frequently encountered when designing LED lighting circuits is that the capacitors in the circuit experience ...

Presented here is a simple circuit that uses six red, green and blue (RGB) LEDs to generate a running-light effect in seven colours—blue, green, red, cyan, yellow, magenta and white. The RGB LEDs have ...

Light-emitting diode (LED) bulbs offer the potential of up to 50,000 hours of operating lifetime, or nearly 25 years of typical usage. This is a 50x improvement over incandescent-equivalent technology ...

The Great American Businessman and Inventor of light bulb – Thomas Alva Edison once said that “We will make electricity so cheap that only the rich will burn candles”, which certainly has become the ...

Abstract: This paper proposes a new current balancing method for alternating current (AC) - light emitting diodes (LED). The proposed method uses the bi-directional current mirror circuit with ...

The deployment of electronic LED lighting has grown dramatically over the past five years. Most luminaire manufacturers now offer a family of high-bay industrial LED products operating at AC line ...
