magnetic ball lamp 2.jpgCheck this out.

Described as the Magnetic 4-Ball Color Changing Lamp, it does pretty much what it says on the tin: it features four magnetically attached balls with LED lights inside that change colors.

Thanks to Craziest Gadgets for flagging this one - it states the balls are removable and adjustable with magnets and are powered by the low voltage power rod in the middle.
Power Integrations.jpgPower Integrations has released an 92% efficient LED streetlight power supply reference design, reports our Technology Editor Steve Bush. For streetlights up to 150W, the supply has a fixed output voltage of 48V at up to 3.125A.

Central to the circuit is the firm's HiperPLC chip, aimed at converters between 80 and 600W, which combines power factor correction (PFC) and a resonant (LLC, inductor inductor capacitor) down converter on the same die.

When you are talking about pilot-less aircraft, their visibility must be an important issue. Well, news we've reported today is that Oxley has developed low profile LED anti-collision lights for BAE Systems' HERTI pilot-less aircraft.

Our technology editor Steve Bush reports that the Rotox 400 produces an effective intensity of greater than 400cd and its light output meets both JAR-23 and JAR-25 regulations.

Check out this ingenious use of LEDs, for time telling.

Basically, "Bulbdial" clocks rely on changing electric light to emulate the principles of sundials. Very impressive in their design, and they look like works of art.
LED trafalgar lights.jpgThis story caught my eye recently - LED lighting will be used in the fountains in Trafalgar Square as part of the 2012 London Olympics.

Apparently the fountains around Nelson's Column have been refurbished, and as well as new pumps to power the water there are LED lighting systems to power some colourful Olympic light shows.

Day one EuroLED

Sorry for the short update but the EuroLED show has been so good for us I haven't had time to go to any of the conference talks which is a real shame, but business now has to come first.

The show side is like a group of friends meeting as in fact the LED market across Europe is in fact a very close network of people; this makes the show very enjoyable as well as a great way to meet a large section or our customer base in a short space of time.

A post about traffic lights takes the garland, and other popular blogs cover car headlights, how to choose a lighting LED, and the colour rendering index...

EuroLED just around the corner

| No Comments | No TrackBacks
So we are at that time of year when all the UK LED companies make the trip to sunny Coventry and the Ricoh Arena for the annual EuroLED conference. The conference has a great line up from the industry to speak and the talks look like producing some interesting discussions. I will do my best to update each day on the highs of the event.

Please don't forgot if you are coming to drop by the Carclo stand - you can't miss it at the front and say hi, or to take a look at the new optics - and to pick the Optical design team's brains for the next generation of optics.
