It seems like the obvious solution to this is to actively increase airflow. Small fans or synthetic jets could be included on the bulbs themselves, although this would be tricky to do compactly, especially for fans. Alternatively, they could be built into light fixtures designed specifically for LED bulbs, which would be less expensive overall, and would allow the cooling to be designed for the specific fixture (face up vs. face down, for example).
