摘要： An LED illuminating device includes a base, an LED substrate mounted on the base, at least one LED on the substrate and an envelope fixed on the base. The envelope includes a plurality of transmission regions and a plurality of reflective regions. The lights beams emitted by the LED reaches the envelope. A first portion of the light beams reaching transmission regions can pass therethough. A second portion of the light beams are internally reflected in multiple times by the reflective regions until they finally escape to outside through the transmission regions. The direction of the light beams can reach various locations of each of the transmission regions at various angles.
