Abstract
An LED unit includes an LED and an optical element. The LED includes a substrate, an LED chip fixed on the substrate and an encapsulation encapsulating the LED chip. The LED further includes a first magnet fixed on the substrate. The optical element includes an optical adjustment layer and a second magnet. The second magnet attracts the first magnet to fix the optical element on the LED. The LED unit can be adjusted to have different optical characteristics by replacing the optical element thereof with another optical element.
