Method and Apparatus for Illuminating Omnidirectional Lighting Using Solid-State Lamps

摘要

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.

主权项

1. A light-emitting diode (“LED”) lamp able to provide illumination, comprising:
a lamp cap containing electrical contacts and able to couple to electrical power supply for receiving electricity; a radiating column having a polygonal prism shape with a top surface of radiating column slightly smaller than a bottom surface of radiating column and the bottom portion of radiating column coupled to the lamp cap, wherein a range of angle between the top surface of the radiating column and side surface of the radiating column is from 90 degree to 120 degree; a plurality of LED devices capable of converting electrical energy to optical energy and configured to distributed on surface of the radiating column for light emanating; and a globe shaped shell coupled to the lamp cap and configured to provide protection to the radiating column.
