Abstract
An LED bulb includes a base, a shell, and a plurality of LEDs. The shell is connected to the base and the plurality of LEDs is disposed within the shell The LEDs are configured to provide the LED bulb with a uniform light-distribution profile. The present disclosure relates generally to light emitting diode (LED) bulbs and, more specifically, to an LED bulb with a gas medium having a uniform light-distribution profile.
