An illumination system (10) for use with a dental hand piece (12) having a proximal end with a light transmitting fiber optic rod (30) and fluid transmitting conduits (20, 22, 24, 26) extending therefrom. The system (10) includes a control unit (100) and an air/water supply tube (78) including a pair of electrical wires connected to the control unit (100). A connector assembly (32) releasably connects the supply tube (78) to the hand piece (12) and includes a connector unit (36) which has longitudinally oriented fluid transmitting channels (70, 72, 74, 76) extending therethrough and an axially aligned socket (64) which is sized for receiving a halogen light bulb assembly (66). A cylindrical strain relief shield housing (38) contains the connector unit (36). A quick disconnect coupling is provided for fastening the strain relief shield housing (38) and connector unit (36) to the proximal end of the hand piece (12) upon a 1/4 turn of a latch ring (48).
