The utility model discloses an LED (Light-Emitting Diode) bulb lamp capable of realizing wide-angle luminescence. The LED bulb lamp comprises LEDs, a heat sink and a lampshade, wherein the heat sink is divided into two parts, the lower part of the heat sink is connected with a lamp cap of a lighting fixture, the upper part of the heat sink takes the shape of a small-top big-bottom multi-surface prismoid, an included angle theta between each ridge surface of the prismoid and the vertical center line of the lighting fixture is greater than or equal to 10 degrees and less than or equal to 25 degrees, the upper part and the lower part of the heat sink are communicated to each other, at least one LED is arranged on each ridge surface, and the upper part of the heat sink is arranged in the lampshade in a covering manner. The LED bulb lamp has the advantages of being capable of enlarging light rays in a small-angle irradiation range to the most of region of a bulb, achieving an entire light distribution effect and giving consideration to requirements on characteristics of luminescence and heat dissipation efficiency.
