Abstract
The application is related to a UV LED package structure for improving light extraction efficiency. An UV LED chip is set on a substrate with an anti-flare film for increasing upward light extraction to concentrate the emitted light by an optical element. Because no glue is filled between the UV LED chip and the optical element, it will be prevented the glue from spoiling and deteriorating by the UV light from the UV LED chip. Thereby, the UV LED package structure can prevent from the light performance reducing.
