Wave27 LED bulb

The project has developed an energy effective replacement for the controversial E27 lighting bulb, which is gradually being phased out. The replacement is going to be a LED- based lightning bulb with the same lightning qualities and also the same mounting as the E27 lightning bulb. It’s going to 90% more energy effective and approx. 50.000 lightning hours.

All lighting experts and environmentalists agree that LED is the most sensible general lighting source in the foreseeable future, but most consumers cling to the compact fluorescent light bulb (CFLB), because it is cheap and more energy efficient than the now banned fluorescent bulb. But the CFLB fails many of the quality and design requirements of a true E27 replacement bulb, notably, the shape, the light quality and color, and the ability to be dimmable. When used in expensive E27 designer lamps the CFLB casts a miserable, muddy and diffuse light. Furthermore CFLBs contain mercury.
Project description

The Wave27 LED lamp bulb is a demonstration project aiming to validate the use of three patented elements to create a completely matching replacement to the Edison 60W incandescent lightbulb (E27). 'Matching' here entails using an 11W LED-based lamp with the same shape and size as the E27, to provide the same brightness (900 lumen) and colour (CRI=90%). The thre essential elements of the demonstration model will validate the ability to: transfer light photons from the Led to a waveguide and transfer LED heat to a heat sink; enter light into a waveguiide; and extract the light via phosphor covered printed overlay to provide 2700 kelvin degrees light. The patented physical principles involved have been validated by external specialists and the actual construction of the demonstration models are scheduled for 2011, with the results aimed at convincing an investor to fund the next stage of roduct evolution towards setting up small scale production

Results

The Wave27 LED E27 replacement bulb represents a breakthrough for LED replacement lighting, which hitherto has been dogged by a very limited lit surface area, heaviness and very high retail pricing.

The Wave27 bulb was originally supported by EUDP for a 12 months development phase, which proved to require 36 months of development effort due to the severe challenges for light alignment and heat transport posed by LEDs of less than 1 square millimetre and an initial temperature surge up to 360 degrees Centigrade. This has led to several complete redesigns as well as a switch in material base.

The result is a wholly lit surface using remote phosphor for light temperature adjustment and an overall weight close to the original E27, and a retail price which is under half of the current price for LED replacements.
