But, he said, "it's not necessarily clear to people in the lighting industry that LED chips were ever meant to go into a bulb." What's really needed, he said, is a new approach to lighting — new fixtures and lamps that spread out the LEDs, avoiding the heat problem.

Yep, the whole world of lighting will be changing in a few years, bulbs will mostly disappear as we duplicate daylight in both large and small areas in a home.

Haven’t seen any activity toward duplicating daylight. They seem to want a certain K, like a 6500K “cool white” or a 2700K “warm white”.

They could do a much better job of duplicating daylight if they wanted to, with mixing phosphors or something, but they don’t really care about that yet. it wouldn’t be too hard.
Philips has a bulb that has the phosphors on the inside, another company is developing a modular system that allows a change in the phosphor disc, for a warmer or cooler white. presumably any combination of phosphors could work. The most efficient led light is the 470nm blue currently, and it’s the efficient 470nm blue chip lighting the phosphors and creating the white.
