Abstract
An LED light bulb has a hollow LED support/heat sink () with fins () extending internally and openings at two ends (). Heat generated by the LEDs () is conducted through the heat sink fins and is removed by a convectively driven air flow that flows through the LED support/heat sink. LEDs are mounted on multiple external faces () of the LED support/heat sink thereby providing illumination in all directions. Lenses () are provided for the LEDs to make the illumination highly uniform.
