LED Lighting guides
Here in one neat package is our collection of key LED lighting articles, covering white LEDs, coloured LEDs, OLEDs and Lighting LEDs...
* White LEDs
* Coloured LEDs
* LED Lighting (1)
* LED Lighting (2)
* LEDs General
* LED Optics
* OLEDs
* Costing LEDs
* LED heatsinking
* 50 year history of the LED
The Fortronic LED and Lighting Design Forum is a one day event free to engineers. It will be held at the Williams F1 Conference Centre, Oxford, on 27 March 2012.
Topics covered will include:
* LED colour/heat selection
* Thermal Management
* Driver Electronics
* Optics
* Light measurement & planning
* Applications aimed at Street, Building, Signage and Theatre,
* Light shaping (diffuser, Software Control/automation).
The organisers write: "The day comprises of 8 presentations in the morning given by speakers from leading manufactures and up to 9 workshops in the afternoon offer in depth design solutions and technical updates. 20 exhibitors support the event in our networking area where there is the opportunity to discuss your requirements with engineers from leading suppliers and network with your engineering colleagues in an informal and club like atmosphere."
For the first time in five years, investment in LED manufacturing is expected to decline 18% this year, after a 36% rise last year, says SEMI, but against a background of general decline, spending in Taiwan and Korea is expected to continue to grow, writes David Manners.
Although demand for LEDs used lighting continued to grow last year reaching a $2.5bn market, demand for LEDs used in backlighting TVs- representing 40% of the LED market - has not met expectations.
However LEDs used in lighting are expected to be a $30bn market in 2020.
Nanoco, a UK-based manufacturer of cadmium-free quantum dots, has
signed a joint development agreement with a global lighting company
which is major producer of LED lighting products, writes Richard Wilson.
The
collaboration will see the university spin-out's cadmium-free quantum
dots (CFQD) technology used in high volume LED lighting systems.
Cree has annouced commercial availability of an LED lighting
module which is capable of delivering 80-lumens-per-watt system efficacy
combined with CRI greater than 90, writes Richard Wilson.
The modules features the supplier's TrueWhite technology for generating white light with LEDs.
"The new modules make the benefits of Cree TrueWhite Technology affordable and widely available," said Mike Watson, senior director of marketing, Cree LED components.
LED lighting is becoming mainstream and luminaire-makers are jumping on
the bandwagon with viable products now that the technology is more
widely understood, writes Steve Bush. 
Fujitsu Semiconductor has introduced a range of 8-bit microcontrollers with embedded flash memory.Start to look into LED lighting and quickly it becomes obvious that one type of LED will not suit all situations.
After a while, you get sophisticated enough to take colour-rendering index (CRI) and colour temperature into account, and even then you are only about halfway down the check list.
A little colour science
There is no scientific definition of white light because, like beauty, white is in the eye of the beholder.
Philips has won a category in the US government's competition to demonstrate the highest efficiency high quality lighting.
Marl is extending its LED strip lighting range.
Rambus has moved into LED lighting with the introduction of an intellectual property (IP) portfolio called Pentelic, writes Steve Bush.

Paul Ward
As Opto Product Manager at Farnell, Paul is overseeing the company's involvement in the rapidly evolving and high profile LED lighting market sector.
As well as ensuring that Farnell offers the latest technologies and products related to solid state lighting, Paul is also responsible for ensuring that the resources are in place to make it easier for design engineers to specify and design-in LED solutions for their applications.
Educated in Production Engineering and Design at Sheffield Hallam University, Paul has worked in various engineering, training and marketing roles for companies including C&K switches, ITT Cannon, Cherry and LED specialist Chicago Miniature Lighting.
Away from the world of LEDs, Paul is a Founder of the charity RTTW, Photographer and Harley Davidson rider; he has ridden and snapped across Europe, New Zealand and the USA on his chrome hog!
Gordon Routledge
Gordon Routledge is one of the original pioneers in LED illumination having worked with LEDs in illumination applications since 1996. Currently VP of Illumination at Dialight, Gordon founded Lumidrives in 2001, having previously been managing director at ACDC Lighting Systems. Gordon has a degree in Electrical & Electronic Engineering from university of Manchester Institute of Science and Technology.
Ian Bryant
Ian Bryant is Business Development Manager LED Division at Carclo Technical Plastics. He has worked on and off at Carclo (Formerly Combined Optical Industrial) since leaving school. He has worked through the company from Toolmaking to starting the company on the road of LED optics business some 6-7 years ago, starting with a standard range and more in line with the business of custom optics. In between all this he has worked in engineering and as a works Director for a hydraulics company but kept getting pulled back to the optics industrial. We are able to offer the full solution from idea to parts so have a very good understanding on what is needed. You will see some posts from our design team also under my name.
