A partially diffusive layer containing a phosphor is mounted above the LED with a gap therebetween. Some of the light emitted by the phosphor is backscattered toward the LED, base, and walls. The LED absorbs a significant amount of the light, while the reflective base and walls efficiently reflect over 90% of the light back toward the phosphor layer for exiting the module. Various equations are provided that allow the designer to select an optimal gap between the LED and the partially diffusive layer to maximize light extraction efficiency out of the diffusive layer. The optimal gap range for maximizing light extraction efficiency is a product of LED largest linear length, LED surface area, base area, wall area, and reflective coefficients of the various elements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light emitting module, a lamp, a luminaire and a display device","description":"A light emitting module includes at least one LED mounted on a reflective base and surrounded by reflective walls to form a cavity.
