The Evolution of LED Lighting Performance Through Use of Proper Optics

Where does LED luminaire performance go from here? For the last several years, the performance of LED luminaires has been compared to traditional HID, florescent and incandescent fixtures using measures such as luminous flux and lumens per watt. These metrics have been valuable because they are easy to measure and show the distinct advantages of LEDs. Now that LED technology improvements are starting to taper off, lighting controls have become part of the next evolution of performance by determining WHEN we use light. As with controls, LED optics offer the opportunity to reduce energy consumption and increase user satisfaction by addressing WHERE we direct the light. Additionally, engineered optics can reduce the cost of the entire luminaire by using as few lumens as necessary to meet the needs of the application. Well-designed optics can assure the correct amount of light in the target area and minimize spillage into other areas, saving energy and increasing the visual quality of the lighting. Often today, a luminaire’s beam pattern is considered only to the extent that it meets the minimum light level requirements in the installation. Whereas with proper optics, a luminaire can significantly increase efficiency by not over-lighting the target area and minimizing the lighting to other areas. Moreover, such optical control requires less luminous flux from the fixture, thus potentially reducing the bill of material costs by reducing LED count, driver wattage, and heatsinking requirements. Come learn how engineered optics can increase the overall efficacy of an LED luminaire, decrease the material cost of the luminaire, and minimize nuisance light. In this program, Ledil will share typical lighting setups and case studies that demonstrate how proper optic design can deliver energy conservation, bill of material savings, and enhanced visual comfort.
