  • Publication number: 20160102849
    Abstract: A solid-state light fixture capable of emitting omnidirectional illumination using light emitting diode (“LED”) is disclosed. The light fixture, in one aspect, includes a base, an LED stand, and a protective shell. In one example, the LED stand has a physical configuration of elongated spherical shaped ball for hosting LED devices. While the base has electrical contacts that are able to connect to electrical power supply for drawing electricity, the elongated spherical shaped ball is configured to distribute electrical current from the base to the LED devices for generating omnidirectional optical light. The LED devices, also known as LED packages, include LED dies configured to be arranged on the surface of the LED stand for light emanating. The protective shell, in one example, protects the LED stand from being contacted by foreign object.
