摘要：
A light output device and manufacturing method in which an array of LEDs (34) is embedded in an encapsulation layer (32). An array of cavities (30) (or regions of different refractive index) is formed in the encapsulation layer (32). The cavities/regions (30) have a density or size that is dependent on their proximity to the light emitting diode (34) locations, in order to reduce hot spots (local high light intensity areas) and thereby render the light output more uniform over the area of the device.
