Abstract:
An LED device includes a substrate, an LED chip and a lens module. The substrate has an upper surface. The LED chip is arranged on the upper surface of the substrate. The LED chip has a light emitting surface away from the upper surface of the substrate. The lens module is arranged over the light emitting surface of the LED chip. The lens module includes a first lens. The first lens includes a first light outputting surface away from the light emitting surface of the LED chip. The first light outputting surface of the first lens defines a first cavity at a center thereof.
