Solid State Lighting: The future lighting technology - more sustainable, responsible and economical
Australia has officially outlawed the sale of incandescent light bulbs this year to advance the use of energy efficient and eco-friendly lighting technologies. The existing replacement strategy is based on compact fluorescent lighting technology, which will deliver considerable savings. The change alone is expected to save around 30 terawatt hours of electricity and 28 million tonnes of greenhouse gas emissions, which is equivalent to taking more than 500,000 cars off the road permanently.
Exciting breakthroughs in photonics and semiconductor research have been recently exploited to develop a new type of light emitter, which can be electrically driven to produce an extremely bright source of light. These new low voltage solid state lighting (SSL) devices are compact, lightweight and long-lasting. The implementation of this SSL technology will significantly lower the world’s electricity consumption, provide attractive cost savings and enable major environmental benefits through the reduction of greenhouse gases.
In this talk, Professor Matthew Phillips discusses the science, technology and applications of SSL devices, together with the major obstacles that must be overcome to facilitate the widespread use of this new green lighting.
