About the Presenter:  Prof. Peter Hiscocks P.Eng is the Chair, Subcommittee on Light Pollution, Royal Astronomical Society of Canada. He is Professor Emeritus in Electrical Engineering from Ryerson University, where he taught courses in analog circuit design and digital systems. Currently he is the CEO of Syscomp Electronic Design, which manufactures low-cost open-source electronic instruments. In 2003, he received the PEO Citizenship Award for his work on the Discover Engineering Summer Camp project.


Synopsis of the Topic:  Artificial light is a great engineering achievement: it has increased our security and enjoyment of night-time hours. But there is a downside associated with the careless use of light at night: light pollution.

Light pollution interferes with human seeing, is a health hazard for humans and other organisms, is a waste of energy, and ruins our view of one of the great natural wonders - the night sky. In this talk, we show examples from the GTA of light pollution - glare, light trespass, overlighting and skyglow. We identify negative effects on humans and the ecosystem. We also show examples of well-designed lighting and indicate how simple measures can better control light and reduce light pollution.

Of interest to engineers, we will describe low-cost tools for the measurement and documentation of illuminance (light level) and luminance (glare) from light sources.
