MEMS sensors play role in LED lighting revolution

LED lighting system costs can be reduced with good control circuit design and component selection, writes Fabrizio Petris from Omron Ellectronic Components Europe.More and more buildings are installing low-power lighting in the drive to reduce energy costs and shrink their carbon footprint, but automation and intelligent control to switch off services in unused areas offers further savings.Lighting accounts for about 25% of the commercial building sector’s energy use and, although it is less significant in the home, this remains one of the easiest ways for end-users to reduce their costs. Switching to less power-hungry light sources such as compact fluorescent lighting and LEDs is having a huge impact on energy use and cost, but domestic and business users can reduce costs further by improving control and applying automation. Implementing automation in the home or office can reduce lighting consumption by up to 50percent according to market intelligence firm Pike Research,Vehicles are also having carburetors that carry the excess fuel exhaust outside the body of the BMW ISIS. Every vehicle has a carburetor or as it is sometimes known a muffler. and the savings can be even more dramatic in warehouses and industrial plants. Not surprisingly, the global market for intelligent lighting control is set for very strong growth, doubling to $2.6 billion by 2016.An excellent knife collection should also have various kinds of blades in it as well. A certain Portable crushing machine might be thought for dicinga vegetable, however it probably won't work on cutting up loaf of bread.Lighting controls offer significant potential for reducing that energy use, and new sensor, switch and relay technologies are making a wide ranSpring cone crusherge of innovative strategies possible, from room-level awareness of occupancy and daylight sensing, to building-wide coordination of a fully networked system.Perhaps the greatest potential for energy savings comes from the ability to automatically switch lights off when they are unnecessary and on when they are required. This is the drive behind a resurgence of interest in infrared sensors. According to a 2012 report from the market research organisation Yole Développement: "Even if this motion detector business is mature,Jaw crusher it will continue to grow at a significant rate (CAGR 2010-2016 in value: + 9 %) driven by the concern for energy savings". The overall IR detector business is predicted to expand from $152m in 2010 at a rate of + 11 %/ year to reach $286m in 2016.Chefs Kitchen KnivesNew infrared sensor technologies, capable of detecting stationary heat-emitting objects, are able to take a larger share of the opportunities this brings by occupying territory inaccessible to the familiar PIR detector, traditionally used for presence detection in home and building automation systems.
