eco lighting product design recycleled adm 2013 conference
DESCRIPTION
Jose Casamayor from ADMEC Nottingham Trent University, explained at The 5th International Conference on Advanced Design and Manufacturing (ADM2013) some mayor topics related to Eco-optimization of Sustainable Lighting Product Design Proccess, using the development of RecycleLED luminaire as a Case study, looking for areas to optimize, results and further optimization work. As results of the research, several improvements were presented, as for instance the possibility to upgrade – new joints, improved thermal efficiency – new heat-sink, using same material and 50 % more thermal efficient, with less components – easier/shorter disassembly time, new joints – easier/shorter disassembly time and better rotation with better ingress protection.TRANSCRIPT

ECO-OPTIMIZATION
Eco-optimization is to optimize a product, by focusing in different areas to maximize/minimize with the final aim to reduce its environmental impact.

CASE STUDY
The Lighting product was developed by Ona Product S.L, Spain and Nottingham Trent University with the support of UK SIS grant and NTU funding
With the support of the European Commission under CIP Eco-innovation programme, the ‘Ecolights’ project consortium members further developed the product for market deployment.
The prototype developed need to be eco-optimized.

AREAS TO OPTIMIZE
Based on the analysis of the ref. prototype several areas were selected for optimization:
1. Access/disassembly: It does not allow easy access for repair and disassembly. Joints have to be broken in order to have access to components or dismantle the product totally.
2. Driver arrestment: Current casing design does not arrest the driver, so this can be damaged if the lighting is moved abruptly, leading to premature end of life of driver.
3. Joints: Units rotate with too much friction among them, which scratches the surface damaging the units’ surface. Also they do not allow units rotate 360°, constraining light control, which lead to energy waste (light were is not needed).
4. Upgrade: More units cannot be added, so the product can become obsolete in a shorter period of time. Modular design allows for upgrade over time.

AREAS TO OPTIMIZE
5. Thermal efficiency-heat sinks: Heat is one the common problems with LEDs. Thermal efficiency of the heat-sink had to be improved to improve heat diffusion and extend the lifespan of the LEDs.
6. Ingress Protection (IP) rating: The product has to satisfy IP 45 standards, in order to be more durable under wet conditions (i.e., toilet).
7. Material reduction: Material used in the casing and other components have to be optimized/minimized.

FURTHER OPTIMIZATION WORK
• Light diffusor: Light output depends on the light diffusor, the design of the diffusor have to be analysed and optimized to produce maximum light output whilst keeping glare levels below human harm threshold.
