Abstract: An LED bulb includes a base and a shell connected to the base. The shell is filled with a thermally conductive liquid for cooling the bulb. A plurality of LEDs is disposed within the shell. A first set of LEDs of the plurality of LEDs is positioned a first distance with respect to the center of a convex portion of the shell, and at a first angle with respect to a centerline of the LED bulb. A second set of LEDs of the plurality of LEDs is positioned a second distance with respect to the center of the convex portion of the shell, and at a second angle with respect to a centerline of the LED bulb. The first distance, first angle, second distance, and second angle are selected such that the LED bulb has a light-distribution profile that varies less than 20 percent in light intensity over 0 degrees to 135 degrees as measured from an axis from the center of the shell through an apex of the shell.

Abstract: A light emitting diode (LED) bulb includes a base, a shell connected to the base forming an enclosed volume, a chassis disposed within the shell, and a plurality of LEDs disposed with the shell. The LED bulb also includes a thermally conductive liquid disposed within the enclosed volume. The LEDs and the chassis are immersed in the thermally conductive liquid. The chassis has a first opening and a second opening. The second opening is spaced from the first opening to facilitate a passive convective flow of the thermally conductive liquid to exchange a first volume of the thermally conductive liquid interior the chassis with a second volume of the thermally conductive liquid exterior the chassis.
