Dr. Ron Gibbons - Dirt Depreciation on Outdoor LED Luminaires
Thu, 13 April 2017, 11:30 AM – 1:30 PM MDT
Doors will be open at 11:30AM with the speakers starting at 12PM. A hot lunch will be provided – please message us after your registration if you have any specific dietary needs.
Light-emitting diode (LED) luminaires present new challenges for those maintaining outdoor and roadway-lighting systems. In other luminaire types, maintenance crews often clean the luminaires when they do a bulk or single relamp, so the lamp life drives the cleaning schedule. However, LED-based luminaires are being marketed as lasting longer and requiring less maintenance than other luminaire types. As a result, they will be exposed longer to environmental dirt and other contaminants that can adhere to the luminaire and reduce the amount of light that reaches the road. This creates a different maintenance paradigm for LED luminaires, and their potential for dirt depreciation should be carefully investigated. This presentation considers the approach, and methods, as well as research results studying dirt depreciation. These results are discussed in the context of today’s changing roadway lighting environment, and makes recommendations to stakeholders in roadway lighting regarding LDD for LED luminaires.
Who should attend:
- Engineers, Lighting Designers;
- Municipality and Facility Managers and Maintenance Personel;
- Electrical Contractors and installers;
- Anyone involved with outdoor lighting and its current challenges.
Food & Drinks: Lunch will be provided as part of the cost. Please send us a message if you have any dietary restrictions.
Location: Executive Royal Hotel – Edmonton.
