Lower an incandescent lamp over the negative you want to scan, and keep it roughly centered on the negative you're going to scan. You need to provide as much light behind the negative so that you'll get enough contrast for a decent scan.
But don't lower the light too far, or the diffuser plate might not mitigate the pattern that your lamp produces, and you'll end up with an odd contrast pattern to your negative. In practice, I got good results from having the lamp about 3 to 4 inches from the scanning surface.
Note that you CANNOT use a flourescent bulb for this purpose. All flourescent bulbs pulsate when they're on, though most people will never notice it. The scanner, however, will pick up these pulses, and render them as bands of alternating contrast levels in the resulting digital image. Incandescent bulbs do not seem to produce similar problems. No idea how LEDs or halogen bulbs would work, but incandescent bulbs are cheap and plentiful, so I would suggest using them.
I was using a typical swingarm desk lamp for this task, and it seems to work well. Its also useful because you can adjust the location of the lamp easily.
