The Cause & Source TM LED Downlight Series
Efficiency LED lighting Optimal reflector design for Flat LED light source tools of combined Efficiency, Effectiveness, Consistency, Reliability and Flexibility System efficacy greater than 50 lms/w * One of the driving factors of LED lighting technology acceptance is the ability to provide expected light while expending fewer natural resources than other alternative technologies commonly referred to as going green. Efficiency, watts, raw lumens, luminous efficiency, system efficacy...lms/w (lumens per watt) The raw lumen output of traditional lamps may appear to When comparing downlighting fixtures on the basis of be greater in comparison to LED sourced lighting fixtures. Efficiency, watts and raw lumen rating is not sufficient data. This is misleading since there is a significant amount of The efficiency of the luminaire is a percentage of how much light wasted with traditional lighting solutions. The LED light escapes the luminaire. More important, the luminous source is directional and emits the majority of the light efficacy of a light source is defined as the light source s output in a specific direction as compared to dispersing lumen value against energy consumption. it in all directions. 50 degree visual cutoff When the consumption of other components in the minimal reflector height luminaire are included (driver, LED module, heat sink, etc.) we call this the system efficacy thus known as lms/w (Lumens per watt). *typical ASTAR open downlights 2.p p.3
Effectiveness ASTAR + XICATO High Performing R9 and CRI When combining reliable components into a downlight design, the sum of the components teamed with the overall luminaire design must provide the design professional and commercial space user with an effective illumination solution. The Best or the Brightest? Effectiveness is determined by effective application, Important R9 Value not seen in CRI Value not how powerful the lightsource appears. Appearance, performance, and longevity must be attained. Lighting solutions to meet the functional and creative needs of the design community.. a source of light but also a part of the final conclusive cause of the space being designed. Color Rendering Index (CRI or Ra) is used to determine how well colors from a light source compare to those from a natural light source such as sunlight. CRI only measures the light source against the first 8 pigment color samples which does not include the important R9 value (as shown left). The R9 value produces strong, vibrant reds which are prevalent in skin tones, clothing, grocery store produce, meats, and art work. Traditionally, less efficient sources such as select halogen, metal halide, or compact fluorescent have been used to achieve required R9 values (as shown left). Standard CRI greater than 80 / R9 greater than 15 Artist CRI greater than 95 / R9 greater than 95 4.p p.5
Consistency 6 All new and fast growing technologies pose the challenge of consistently producing the same design over time under varied conditions. This has been a production challenge for decades and will continue. Computer controlled aluminum oxide anodizing for superior surface. The industries first 5 year warranty that guarantees modules in an installation will deliver visually consistent light from luminaire to luminaire 4 Therefore, a great light source must be evaluated as consistent in color and output when new and over time so that the original design of the space is not altered, interrupted, or deprived of any benefits. Consistent Color for Life LED luminaires are composed of a number of The Xicato Five-Year Color Consistency and Lumen Maintenance Warranty is the first industry warranty that guarantees modules in an installation will deliver visually consistent light from luminaire to luminaire for a five-year period. End users and specifiers alike can now act with Color Consistency and Lumen Maintenance Warranty (5 years) components including a reflector, heat sink, power supply, and the light source. A high quality light source or LED module is the major key for consistent color. confidence knowing that, finally, there is legitimate backing for the long-term performance of an LED-based lighting installation. SDCM (Standard Color Deviation Matching) is a measurement along two color axis to determine the color likeness between LED modules (sources). Xicato s SDCM is described as one step by 2 steps (1x2) which means that the variation between LED modules are imperceptible. Downlights should be not more than one step apart on ther vertical axis and two steps apart on the horizontal axis. 6.p p.7
Reliability Superior Heat Removal Today, warrantees are marketed to promote a comfort for the consumer and a determining factor in final decision making. Our philosophy is capped with the selection of dynamic LED technology component providers that have a sole stake in the NO ACTIVE COOLING NEEDED product that they provide thus reliability becoming a must. Reliability must be a result of a great design and not superseded by a limited warranty policy. ASTAR teamed with XICATO, arguably the most progressive and reliable LED source solution in today s market. Also partnered with Philips, a leader in LED driver solutions. Rated System Life of 50,000 hours at 70% lumen output (L70) provides maintenance-free downlighting for 16 years*. No Active Cooling components of any type required *typical commercial office 12 hour/work day of lighting operation. 8.p p.9
Flexibility Quick Disconnect Flex Connector System A system perspective must be used to produce versatile downlight fixtures with dimming, daylight harvesting, and Tooless LED Source thumb screw design integration energy management adaptation while offering a family of open, wall wash, and lens options. Flexibility, controllability and application driven options are essential. LEDsource System consists of a tooless replaceable and interchangeable LED lightsource consisting of a combined; LED module, heatsink, quick disconnect flex power feed, and mounting plate. A change in lumen module selection is a snap with all ceiling types. Dimming is standard. Flicker-free 0-10V controllability, 10% dimming at no additional cost. Optional Lutron Hi-Lume A-Series driver allows for smooth, continuous, 1% dimming. Removable/ replaceable/ upgradable LED source (tooless) 10.p p.11
