An LED lighting device includes an encapsulation, a number of LED light sources and a light guiding member. The light guiding member is arranged inside the encapsulation, and includes two opposite curve surfaces, at least one of which defines a number of accentuated portions. One end of the light guiding member defines a light incident surface opposing the LED light sources. After entering the light guiding member from the light incident surface, the light beams from the LED light sources are reflected between opposite surfaces of the light guiding member. The light beams reaching the accentuated portions are diffused and exit the light guiding member, and finally being transmitted outside through the encapsulation. |
