Low energy consumption illumination sources based on collimating optics

  • PhD Student: Sina Babadi

This exciting project, which involves collaboration between GCU, Heriot-Watt University and Optical Antenna Solutions Ltd., aims at developing an energy efficient LED-based lamp incorporating non-imaging optics for use in poles above 6 meters. This lamp will be used for street illumination and should be capable of satisfying CIE and IEC standards with regards to footprint, spectral emission, thermal performance and safety, which current LED based lamps fail to meet, precluding them from replacing energy-inefficient sources of illumination.

The PhD student will be responsible for designing, integrating and testing a low energy consumption LED-based illumination system based on non-imaging concentrators. The specific objectives of the project are:

a) To investigate, design and implement a non-imaging optical element (such as a 3D dielectric totally internally reflecting concentrator - DTIRC), capable of providing an adequate footprint at distances above 6 meters when combined with LEDs.
b) To carry out a performance analysis of such a system through integrated optical-thermal simulations and experimental work.
c) To investigate relevant low-energy consumption modulation schemes for the LED lamp driver.
d) To investigate relevant safety issues of this system and its compliance with IEC and CIE standards.
