ABSTRACT:
An exemplary light emitting diode (30) includes a light output unit (31), an optical lens (33) and a reflective film (35). The optical lens includes a light input surface (331) facing the light output unit, a top interface (333) opposite to the light input surface, and a light output surface (335) between the light input surface and the top interface. The reflective film is integrally formed on and in immediate contact with the top interface of the optical lens. The reflective film is made of a transparent resin matrix material dispersed with a plurality of reflective particles. A method for making the light emitting diode is also provided.
