The master control unit is configured for controlling the operation of a remote light unit based on a signal received from a remote control unit. The light unit comprising at least one light source. ## Claims ### Claim 1 A hands-free lighting system, said hands-free lighting system comprising: a master control unit, a light unit, and a remote control unit; wherein said master control unit is configured for controlling the operation of said light unit, said master control unit connects to said light unit, said master control unit connects to said remote control unit; wherein said light unit comprises at least one light source, wherein said light unit is remote from said master control unit; and wherein said remote control unit comprises at least one user control for receiving input from a user, wherein in response to user input, said remote control unit sends a signal to the master control unit, wherein said master control unit, upon receiving said signal, controls the light unit as instructed by the signal. ### Claim 2 (depends on 1) The hands-free lighting system of claim 1, wherein said user control comprises at least one input device. ### Claim 3 (depends on 1) The hands-free lighting system of claim 1, wherein said user control comprises at least one sensor. ### Claim 4 (depends on 1) The hands-free lighting system of claim 1, wherein said at least one sensor is located external to said remote control unit. ### Claim 5 (depends on 1) The hands-free lighting system of claim 1, wherein said master control unit comprises a power source. ### Claim 6 (depends on 5) The hands-free lighting system of claim 5, wherein said master control unit connects to said light unit via a wired connection, and wherein said power source powers said light unit. ### Claim 7 (depends on 1) The hands-free lighting system of claim 1, wherein said master control unit connects to said light unit via a wired connection, and wherein said master control unit controls said light unit via at least one control signal sent through said wired connection. ### Claim 8 (depends on 1) The hands-free lighting system of claim 1, wherein said master control unit connects to the remote control unit via a wireless connection. ### Claim 9 (depends on 1) The hands-free lighting system of claim 1, wherein said master control unit connects to said remote control unit via a wired connection. ### Claim 10 (depends on 1) The hands-free lighting system of claim 1, wherein said master control unit comprises at least one master input device for allowing a user to operate said master control unit. ### Claim 11 (depends on 1) The hands-free lighting system of claim 1, wherein said remote control unit comprises a power source. ### Claim 12 (depends on 1) The hands-free lighting system of claim 1, wherein said light unit comprises a first light source, and a second light source, wherein said first light source comprises at least one first light element configured as a dental curing light, and wherein said a second light source comprises at least one second light element configured as an illuminating light. ### Claim 13 (depends on 12) The hands-free lighting system of claim 12, wherein said first light element comprises a light emitting diode, and said second light element comprises a light emitting diode. ### Claim 14 (depends on 12) The hands-free lighting system of claim 12, wherein said first light element and said second light element emit light in the visible blue light spectrum. ### Claim 15 (depends on 14) The hands-free lighting system of claim 14, wherein said second light source further comprises a visible blue light spectrum filter for preventing the passing of visible blue light from the second light element through the filter. ### Claim 16 (depends on 12) The hands-free lighting system of claim 12, wherein said first light element and said second light element emits light in the visible blue light spectrum, and said second light element does not emit light in the visible blue light spectrum. ### Claim 17 A hands-free lighting system, said hands-free lighting system comprising: a master control unit, a light unit, and a remote control unit; wherein said master control unit is configured for controlling the operation of said light unit, said master control unit connects to said light unit, said master control unit connects to said remote control unit, said master control unit comprises a power source, said master control unit connects to said light unit via a wired connection, and said power source powers said light unit; wherein said light unit comprises at least one light source, wherein said light unit is remote from said master control unit; and wherein said remote control unit comprises at least one user control for receiving input from a user, wherein in response to user input, said remote control unit sends a signal to the master control unit, wherein said master control unit, upon receiving said signal, controls the light unit as instructed by the signal. ### Claim 18 (depends on 17) The hands-free lighting system of claim 17, wherein said user control comprises at least one input device, at least one sensor, or a combination of at least one input device and at least one sensor. ### Claim 19 (depends on 18) The hands-free lighting system of claim 18, wherein said light unit comprises a first light source, and a second light source, wherein said first light source emits light in the visible blue light spectrum, and wherein said second light source does not emit light in the visible blue light spectrum. ### Claim 20 A hands-free lighting system, said hands-free lighting system comprising: a master control unit, a light unit, and a remote control unit; wherein said master control unit is configured for controlling the operation of said light unit, said master control unit connects to said light unit, said master control unit connects to said remote control unit, said master control unit comprises a power source, said master control unit connects to said light unit via a wired connection, and said power source powers said light unit; wherein said light unit is remote from said master control unit, wherein said light unit comprises a first light source and a second light source, wherein said first light source emits light in the visible blue light spectrum, and wherein said second light source does not emit light in the visible blue light spectrum; and wherein said remote control unit comprises at least one user control for receiving input from a user, wherein said user control comprises at least one sensor, wherein in response to user input, said remote control unit sends a signal to the master control unit, wherein said master control unit, upon receiving said signal, controls the light unit as instructed by the signal. ### Claim at position 21 21-29.
