ABSTRACT:
An exemplary light emitting diode (30) includes a light output unit (31), an optical lens (33), and a reflective sheet (35). The optical lens is mounted on the light output unit. The optical lens includes a light input surface (331), a generally funnel-shaped top surface (333) and a light output surface (335). The funnel-shaped top surface is distal from the light input surface. The light output surface generally between the light input surface and the top surface is an annular bulging surface. It is relatively easy to configure an injection mold for making the optical lens.
