Light emitting diode having grooves to modulate light emission thereof |
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.
