Patent number: 9548432Abstract: A light output device and manufacturing method in which an array of LEDs is embedded in an encapsulation layer. An array of cavities (or regions of different refractive index) is formed in the encapsulation layer. The cavities/regions have a density or size that is dependent on their proximity to the light emitting diode 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.Type: GrantFiled: March 1, 2016Date of Patent: January 17, 2017Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Hugo Johan Cornelissen, Giovanni Cennini, Hendrikus Hubertus Petrus Gommans, Marcellinus Petrus Carolus Michael Krijn, Martinus Hermanus Wilhelmus Maria Van Delden, Leon Wilhelmus Godefridus Stofmeel, Jianghong Yu
