Abstract
LED lighting fixtures capable of providing even luminous intensity distribution are disclosed. An illustrative lighting fixture includes a base, a pedestal, a substrate, first and second LEDs, and light transmissive cover. The base is in electrical communication with a power source. The pedestal is on the base. Mounted on the pedestal is the backside of the substrate. The first and second LEDs are mounted on the front and back sides of the substrate, respectively. The light transmissive cover substantially encapsulates the substrate and the first and second LEDs.
