Abstract

An LED bulb includes a base, a shell, a plurality of LEDs, and a thermally conductive liquid. The shell is connected to the base. The plurality of LEDs is attached to the base and disposed within the shell. The thermally conductive liquid is held within the shell. The LED bulb is configured to produce a uniform light-distribution profile.
