An omnidirectional LED light bulb comprising a bulb head (1), a heat dissipating housing (2), a circuit board (5), an LED light source (3), and a bulb cover (4). The heat dissipating housing (2) is provided with a protruded platform (6) with a pillar-shaped LED light source (3) of multi-prismatic pillar head. LED chips (9) are arranged on the top and lateral surfaces of the pillar head, and a circular reflective surface (10) is arranged on the rear end of the pillar head. The LED light bulb has the advantages of high rear end light flux, omnidirectional luminescence and uniform illumination. |
