In various embodiments, an illumination device features an ultraviolet (UV) light-emitting device at least partially surrounded by an encapsulant. A barrier layer is disposed between the light-emitting device and the encapsulant and is configured to substantially prevent UV light emitted by the light-emitting device from entering the encapsulant.

Ultraviolet light-emitting devices and methods

In various embodiments, an illumination device features an ultraviolet (UV) light-emitting device at least partially surrounded by an encapsulant and having a rigid lens. Downward forces is applied while the encapsulant is at least partially cured to substantially prevent partial or full detachment of the rigid lens from the light-emitting device, and/or substantially suppress formation of bubbles between the light-emitting device and the rigid lens.
