摘要: A light emitting diode (10) includes an LED chip (14) and an encapsulant (16) enclosing the LED chip. The LED chip has a light emitting surface (141), and the encapsulant has a light output surface (161) over the light emitting surface. The light output surface defines a plurality of annular, concentric grooves (163). Each groove is cooperatively enclosed by a first groove wall (165) and a second groove wall (166). The first groove wall is a portion of a circumferential side surface of a cone, and a conical tip of the cone is located on the light emitting surface of the LED chip.

摘要: A heat dissipation device includes an electric fan having a fan impeller with a hub and a heat sink. A plurality of main blades and subsidiary blades extend radially and outwardly from the hub and alternate with each other. The electric fan forms an air inlet and an air outlet. The main blades have connecting portions on the hub which are extended towards a center of the hub at the air outlet. The subsidiary blades have a smaller radial length than the main blades. The subsidiary blades each have a connecting edge on the hub which is extended toward the center of the hub adjacent to the air outlet. The fan impeller drives more air to the center of the air outlet, whereby more air can flow to a center of the heat sink.
