Abstract
A light emitting diode device includes a substrate, a frame, an LED die and a transparent layer. The frame is located on the substrate. The frame and the substrate collectively define a concave portion. The frame has a light reflectivity ranging from 20% to 40%. The LED die is located on the substrate and within the concave portion. The transparent layer is filled into the concave portion and covering the LED die, wherein the LED die has a side-emitting surface and a top-emitting surface, the side-emitting surface has a luminous intensity greater than that of the top-emitting surface.
Claims9
