Abstract

An LED bulb includes a stem body, a shell, a plurality of LEDs, and a thermally conductive liquid. The shell is connected to the stem body. The plurality of LEDs is disposed within the shell. The thermally conductive liquid is held within the shell. The LEDs and the shell are configured to provide the LED bulb with a uniform light-distribution profile.
