Abstract

The present invention is a technique which may be employed to precisely control the intensity of illumination of such a lamp. As depicted in the figure, microprocessor 12, preferably an Intel 8051@ microcontroller, is used in conjunction with analog-to-digital (ND) converter 14, digital-to-analog (D/A) converter 16, comparator 18, integrator 20, and power MOSFET 22 to implement the control algorithm.
