lamps, compact uorescent lamps (CFLs), and LEDs. Fortunately, the nature of lighting grants us a wider repertoire of ecacy optimization methods than is available to display applications. For example, we no longer need to worry about resolution and ambient contrast, which gives us freedom to explore techniques to increase light extraction from the device and allows us to achieve signicant improvement in device ecacy. is chapter will provide an overview of light extraction relevant to lighting; see Chapter 12 for a detailed discussion of light extraction.
