LIQUID-FILLED LED BULB HAVING A UNIFORM LIGHT-DISTRIBUTION PROFILE

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 co...

Beschreibung
Zusammenfassung:	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.
