Direct-type light emitting diode backlight module

摘要

A direct-type LED backlight module includes a backlight plate, an LED mounted on the backlight plate to emit light, and a lens mounted on the backlight plate and encapsulating the LED therein. The lens includes a light input part to allow the light in, a light output part extending from a top surface of the light input part to allow the light radiate out from a periphery thereof, and a microstructure formed on a bottom surface of the light input part to reflect a part of light reflected by the light output part to make the reflected light travel through a central portion of the light output part.

1. A direct-type light emitting diode (LED) backlight module comprising:
a backlight plate; an LED mounted on the backlight plate to emit light; and a lens mounted on the backlight plate and encapsulating the LED therein, the lens comprising a light input part to allow the light incident in, a light output part extending from a top surface of the light input part to allow the light radiate out from a periphery thereof, and a microstructure formed on a bottom surface of the light input part to reflect a part of light reflected by the light output part to make the reflected light travel through a central portion of the light output part.
