Humidity? Dust? Sand? Corrosion? Performance? Drivers? Answer is: QUALITY fixtures & lighting design address all the above There are no issues in specifying LEDs for Middle East external use...if • Correct technical LED Specifications are written and enforced through all project stages and approval process • Correct lighting design criteria/standards/brief are issued • Consultant/Designers are required to Specify and Design correctly • Any ‘Equal & Approved’ submissions and/or value engineering is monitored and controlled World Future Energy Summit 2013 20 Standards & Specifications: Abu Dhabi Sustainable Public Lighting Policy ADM – No Pre-Approved Material Lists for Lighting Equipment • Implemented by ADM as the way forward to ensure as new technology and fixtures come to the marketplace, new fixtures can immediately be proposed on projects with the DMA Specifications’ technical criteria as the benchmark to be adhered to • All luminaire/component submission material shall be provided in full as part of the whole design process for consideration by ADM and their Consultants on each project on a project-specific basis • ADM want to check that not only fixtures technically comply, but also they are used in the correct manner and appropriate to the specific project • Lists of fixtures (for LED especially) may become obsolete very quickly compared to the next cheaper/better generation coming through. Even by the time some fixtures go through a lengthy pre-qualification approval process and make it onto a list, they might be immediately superseded World Future Energy Summit 2013 21 Standards & Specifications: Abu Dhabi Sustainable Public Lighting Policy LED Fixture Specification for Projects The key areas to define with benchmarks/criteria • LED Fixture efficacy • LED Fixture thermal design • LED Fixture testing performed at actual local maximum nighttime temperature/humidity, plus safety factor • Storage (or daytime) temperature tolerance of components and fixtures • LED source colour temperature and rendering • LED chip binning/full luminaire chromaticity coordinate testing • Driver specification • IP, IK rating & corrosion/environmental resistance • Photometry • Useful Life calculation criteria • Photobiological safety • Long warranties World Future Energy Summit 2013 22 Standards & Specifications: Abu Dhabi Sustainable Public Lighting Policy LED Fixture Specification LED Fixture Efficacy (Example- Road Fixtures) Whole Luminaire Efficacy: The optimum efficiency of the luminaire shall be confirmed as follows: Minimum luminaire efficacy shall be: ≥ 75llm/cctW (@min50-degC, min95%RH Which is given as Total Luminaire Design(Deliver) Lumen Output (llm) over Total Luminaire Circuit Watts(cctW) at minimum 50-degrees Centigrade Operating Outside Ambient Temperature and minimum 95% Relative Humidity. The efficacy being stated at minimum 50 Deg C (Greater than or equal to 75 llm/cctW) should be supported by a thermal test report for the luminaire. This report should provide percentage depreciation of light output at 50 Deg C from testing value of 25degreeC or 35degreeC. This can be compared with LM-79 efficacy at lab temperature from photometric report and de-rated. The effect on the driver case temperature at minimum 50degreeC should also be shown. World Future Energy Summit 2013 23 Standards & Specifications: Abu Dhabi Sustainable Public Lighting Policy Whole Luminaire Efficacy This is becoming the international standard for judging/specifying the lighting efficiency (efficacy) of led luminaires as it takes into account all of the various losses associated with combining the numerous components into an operating lighting fixture: • • • • • Actual LED lumen output once mounted in a board/module Thermal losses from encasement and operation conditions Optical losses due to refractors, reflectors, diffusers and/or covers Drive Current Electrical and Driver losses It can be considered a true fixture efficiency comparison and also, in the case of the DMA Lighting Specifications, used to set the minimum efficacy criteria required for specifying. New International guides are all moving in this direction too.
