Assignee:
3M Innovative Properties Company - Saint Paul MN
International Classification:
H01L 33/00
US Classification:
257 98, 257E33001
Abstract:
Disclosed herein are LED devices having lenses and methods of making the devices. The LED devices are made using an optical layer comprising a plurality of lens features. The optical layer is disposed relative to the LED die such that at least one LED die is optically coupled to at least one lens feature. A lens can then be made from the lens feature and excess optical layer removed to provide the device.
