摘要：A dome light is disclod which utilizes a rotating knob with ‘on’ and ‘off’positions to toggle between having either a halogen bulb on or a plurality of red LEDs on, or both off. Dual D-type flip-flops toggle the dome light between states in respon the changes of the knob between the ‘on’ and ‘off’ positions. The plurality of red
LEDs utilize at least one current regulator to maintain a constant level of illumination. When the halogen bulb is on, further rotation of the knob varies a potentiometer which controls the duty cycle created by a pul width modulator. The pul width modulator caus the halogen bulb to be on for portions of each cycle; the longer the ‘on’ time during each cycle, the greater the apparent intensity of illumination by the halogen bulb.
