ABSTRACT:
A light emitting diode (LED) illumination device (10) includes an LED (11), a frustum-shaped light guide member (12) and a light diffusing plate (13). The frustum-shaped light guide member (12) has a light input surface (120) and a light output surface (122) opposite to the light input surface (120). The light guide member (12) tapers from the light output surface (122) to the light input surface (120). The light input surface (120) is optically coupled to the LED (11), and the light diffusing plate (13) is optically coupled to the light output surface (122) of the light guide member (12).
