Lighting Communications Development Platform Intelligent Lighting & Control Solutions Summary Irrespective of the lighting technology, the ability to effectively control the light source is essential. Beyond a simple on/off switch, advanced lighting control provides the opportunity to provide additional intelligence and increased energy savings. The ability to dim any light source is the most common requirement of a light controller—but is a potential obstacle. Most legacy dimmers are simple triac dimmers that can vary the light output of an incandescent light source from 0–100%. These vary the brightness by “chopping” the AC line voltage and controlling the effective power to the lamp, thereby varying the light output. These methods function well with incandescent sources, as well as some specially designed CFL ballasts, but do not function properly with most existing drivers or ballasts. In order to effectively dim LED and fluorescent, specialized methods such as varying PWM frequency or variable current is required—this is easily implemented with electronic dimming controllers. Functions such as dimming and timers are common, but intelligent control provides opportunities to enrich the user experience and increase value. Incremental energy savings can be provided by potentially integrating elements such as energy management and harvesting (ie. solar), ambient light compensation (reducing light output based on other localized light sources), and occupancy or motion sensing. Further intelligence includes the ability to create lighting networks that communicate both locally, as well as to remote locations. This allows for the ability to increase energy savings further and reduce maintenance cost via items such as fixed light output in lighting arrays (ie. street lamps, large rooms, etc.), monitoring light output, and providing real-time operating issues. Additionally, this offers the ability to integrate lighting into other system topologies such as security systems or automation & control. Aesthetically, lighting control offers the ability to support custom mood lighting by varying brightness, color, and color temperature—across large lighting arrays. Example Configuration DALI/DMX512A Adapter Main/Prototyping Board DALI/DMX512A Adapter Main/Prototyping Board Features The Lighting Communications Development Platform provides a universal lighting development platform for the creation of communications enabled lighting applications. The Lighting Communications Development Platform consists of: ■ Main communications board ■ Prototyping board ■ Communications interface adapters (DALI, DMX512A, future protocol support (eg. RF)) The following is required: ■ Minimum of (2) main or (2) prototyping boards ■ Minimum (2) adapters • Connected via appropriate cabling • RJ45 patch cable • DMX512A 5-pin barrel cable • DALI 2-wire The communication platform is compatible with commercially available DALI/DMX512A products and can be integrated into existing lighting networks during development or utilized with multiple communication platforms to simulate large lighting networks.
