The increased functionalityand flexibility of the ChromaWhite modulesreduces the overall cost on many levels.For example, reduced manufacturing costs areenabled by zero color binning; a reduced bill ofmaterials results from the manufacture of onemodule for all color bins; and the use of multichip,high-power LED COB modules enables alow cost per LED die.At the customer and system level, benefitsinclude a minimal requirement for secondaryoptics due to the use of board-level optics, andthe ability to use smaller, lower-cost heat sinksdue to a reduced thermal luminaire load. Theuse of board-level LED drivers means that onlysimple, low-cost power supplies are required.Due to the system level complexity and zerobinning, the price per kilo-lumen for ChromaWhiteLED modules can be 50% lower thanfor conventional single-color white LED clusters.However, when the ChromaWhite LEDmodules are embedded in the lighting application,the compounded benefits enable dramaticallygreater benefits, with up to 80%reduction in overall luminaire cost.ConclusionsLED lighting technology has recently reachedefficiency levels matching or exceeding themost efficient conventional lighting technologies.With the added benefits of superiorlifetime and unlimited flexibility, LEDtechnology is widely considered the futureof intelligent lighting.The transformation of dumb luminaires intofully color-tunable, intelligent lighting solutionsopens up the design space while providingfurther impacts in areas of lifestyle, healthLINKSand well-being. As an example, the emulationof sunrise, daylight and sunset (in both colortemperature and time during the day) duringthe winter seasons can help in the regulationof circadian rhythms and minimization in thesymptoms commonly associated with lack ofsunlight such as seasonal affective disorder(SAD). The ability to adjust the CCT and boostspecific wavelengths can also help in alertnessand potentially benefit adult concentration inthe work environment and learning in students.By providing the necessary breakthroughsin LED lighting, the PhotonStar ChromaWhiteLED module, available in 1Q09, willhelp accelerate mass-market adoption and fulfillthe future creative desires of lightingdesigners as well as the energy efficiencyrequirements of environmentalists.
