ABSTRACT:
A light emitting diode (“LED”) device that emits omni-directional light is disclosed. Such omni-directional LED device may include a LED chip capable of emitting light in all directions. In one example of one implementation, the LED chip is then assembled and sealed inside a casing, such as a glass casing or tube that is capable of emitting light in 360 degree beam pattern. Further, the anode and cathode, or P or N-type contacts, may be configured on the LED chip such that light is allowed to emit from the top and/or the bottom surface of the LED chip in the LED device and is further able to reflect outward and fill the casing or tube of the LED device with light capable of emitting omni-directionally.
