February 2010 Archives

There's no doubt that LED technology is rapidly changing the lighting industry and how we interact with light. It is a truly disruptive technology, probably synonymous with going from computer programming in the punch card era to using a microchip, or going from a rotary phone to a touch screen iPhone.

In the future, we won't purchase a light fixture with a separate screw-in Edison light bulb. All of a sudden, we will be buying a complete lighting system with the LEDs already inside.

LED traffic and street lights, a perfect application for both colour and white light sources, have led the way with more than 1 in 3 traffic signals in North America now converted to LED.

An LED related "How To" article has been posted on the site - How to design dimmers for multiple LEDs

Written by Michael Bairanzade, application engineer and Marie-Therese Capron, director, low voltage power management at ON Semiconductor.

They write about how an embedded gradual dimming function provides an easy way to generate the special illumination sequences being requested by portable goods manufacturers. This provides a way, they say, that they could differentiate themselves from their rivals.

Hi all I am off to the USA on Monday to be part of the Strategies and Light. We are part of the program as Jim will be doing a talk. Also, we have a stand so pop by if in the area.

 

I will post during the week on important updates from the conference.

cree 1500 lumens.JPGUsing a multi-chip package, Cree has developed an LED that will compete with 75W light bulbs, writes Technology Editor Steve Bush.

It is called the XLamp MPL, and the 12x13mm device will eventually deliver up to 1,500 lm at 750mA, which is 75 lm/W.

Each device has three strings of eight die and at 750mA, 250mA per string, forward voltage is typically 26.5V.
