Local councils have been forced into taking yearly reductions in funds to manage their public lighting. Therefore, they have been looking towards more efficient alternatives to existing lighting. The three main ways public lighting systems have started to become more efficient is by replacing the commonly used high pressure sodium lamps with new high-power LEDs, by using sensors to control light level, and by using renewable source to power lights.
Also the EU has recently released the EU Energy Directive which states that by 2020 EU countries must produce 20% of their energy from a renewable source.
Lumen-air is a solely renewable powered lighting system which uses a vertical axis wind turbine linked to the generator to charge the battery bank, found in the base of the lighting post. Due to the high winds at the coast, it was decided a wind turbine was a more reliable renewable source than solar.
The product uses two sets of high-powered LEDs to light the surrounding area. Use of both a passive infrared sensor and a light dependant resistor helps control light levels and reduces output of the battery bank. The product has been designed so it fits onto existing 4m high lighting posts giving councils the option of reusing existing posts.
My time at Bournemouth University has allowed me to develop on my design skill set preparing for a career after university. I would like to thank the team of lecturers for help and guidance throughout the past four years.
