Designer’s touch A1 Lighting catches up with luminaire designer David Morgan.

David Morgan knows a thing or two about lighting. He has worked with hundreds of lighting companies around the world to create new lighting products and systems. Morgan’s career began at Thorn Lighting, and after leaving David Morgan Associates was born, and the company will be 30 years old in March. Morgan set up Radiant Architectural Lighting a few years ago so that the company could widen its market and work directly with lighting designers on their projects. Q What is your favourite project you have worked on and why?

‘The high power LED uplight we designed with Maurice Brill Lighting Design for the Regent’s Place pavilion project in London has been a successful example of the way our business with lighting designers has developed. We created the LED uplight for this project to produce a specific lighting effect in terms of power, distribution and colour within a very limited space constraint.’ Q Which luminaire do you wish you had designed and why? ‘The Spock range from Modular seems to be a very ingenious solution to getting a low glare medium beam distribution from LED emitters in a very elegant luminaire. The light output from LED arrays and emitters is increasing very quickly so the problems are now about how to control the amount of light,


reduce glare without killing efficiency and dealing with the thermal management issues which often seams to mean large ugly heat sinks on view. Spock seems to have dealt with this.’ Q What's your favourite piece of lighting equipment at the moment? ‘The Taccia table light, designed by Achille Castiglioni and Pier Giacomo Castiglioni in 1962, is still one of my favourite lighting objects. I would be very happy to have designed just one product that has the quirkyness, light quality, elegance and charm of the Taccia.’ Q What are you working on at the moment? ‘For the past year it feels as though we

were only working on LED products, including a lot of new and custom versions of the Radiant Architectural Lighting systems. After exhibiting at ARC and Light+Building we have had a lot of requests for our bendable LED cove and wall/curtain grazing lighting systems for use in hotels in the middle east and for private residences in the UK and Europe. We are continuously reviewing the types of LED used in these systems as new and improved emitters and arrays are introduced. For some reason we have recently been asked to return to a wider variety of light sources for clients in the UK, India and the USA. We are developing new fluorescent office lighting products, architectural downlights that can use halogen, CFL and LED sources, as well as a new range of image forming gobo projectors using halogen, CDM and LED sources.’

Q What new lighting product developments are you excited about at the moment? ‘I very much like the LED arrays from Bridgelux, Citizen, Xicato and Sharp and are using these in a lot of developments. Philips and Osram are now offering LED arrays so that probably means that this is the way the market will develop for a while. At last we have an LED source that gives a high light output in a small package and does not need to be mounted onto a PCB. We are getting back towards the traditional lighting industry format of separate light sources, control gear and mechanical housings that allows the multiplicity of product variants that the market requires. I am also very interested in plasma lamps for architectural lighting. I think for high lumen applications plasma sources have most of the advantages of LED but with a much smaller point source that can be controlled for use in narrow beam projectors. I think this is an emerging technology that will develop despite the growth of LEDs. At the moment the efficiency is not high enough, but hopefully it will improve.

I am waiting for the new flexible OLED material from GE as that could then make this technology one that has some real uses in lighting projects – but it could be a while yet before the technology is stable and cost effective.’
