LED light bulbs capable of providing even luminous intensity distribution are disclosed. An illustrative LED light bulb includes a base, a light transmissive cover and upstanding light bars. The base is capable of being in electrical communication with a power source and has a screw axis and a periphery. The light transmissive cover is substantially mounted on the periphery. The upstanding light bars are mounted radically around the screw axis and located between the screw axis and the periphery. The upstanding light bars are arranged to substantially shine inward to the screw axis. |
