Back to it

Submitted the final assignment for this semester of my Masters in Illumination Design.  It's been a hectic time since returning from Canada and LPTMM2015 and ALAN2015.  Hoping I can get a SOLIS meeting up over the coming week, meetings have been delayed and reorganised this year because of my university commitments.

And back to LPTMM2015, the website has been updated and can be found here : LPTMM2015 just like you attended the conference - and without the jet lag.  All of the presentations are fantastic material if you're interested in the effects of light in our environment.  Not only for humans, also for wildlife, it's important to acknowledge that animals may see in a different part of the spectrum to humans and that lighting must also be tuned to the needs of wildlife, two of the talks were on the topic of wildlife, Robert Dick of Canada spoke on a luminaire designed to have a low impact on wildlife and Kellie Pendolly and Rob Ryan (the other Australians at LPTMM2015), Kellie is a an environmental scientist specialising in turtles and marine science, find her here Pendolly Environmental .

CCT not always blue
Robert Dick was in Australia recently attending World Parks Conference in 2014, hoping that he could convince environmentalists of low CCT lights with a low emission component of blue light.  So I'm stealing a couple of images from his presentation.  Roberts presentation centred on the human response to light, and how a high CCT is not always correlated to spectrum, it depends on manufacturer and that some LEDs have a low CCT but a strong emission in the blue spectrum.

And the result could be something like this.
