## Abstract

A hands free integrated personal task lighting system for dental or surgical use providing remote control light activation and selective adjustable light intensity output. A fixed output value light source on a headset has an electronically activated variable transmission glass which changes transparency to degrees of translucentness by varied electrical activation. The light system provides both remote light activation and illumination value control by variable control sensors in a hands-free environment.

## Claims

### Claim 1

A hands free variable task lighting system for medical procedures comprises,
a control module, a light assembly, and a source of power,
said control module configured for illumination control of said light assembly by selective power supply voltage to said light assembly,
said light assembly comprising,
a light source, a selectively activated smart glass panel optical transparency responsive to varied voltage from said control module,
said smart glass panel in optical alignment with said light source, at least one user control receiving input from a user, said user control comprises at least one input device.

### Claim 2 (depends on 1)

The hands-free variable task lighting system for medical procedures set forth in claim 1 wherein said control module comprises,
a power source, selective control of power to said light source and varied voltage supplied to said smart glass panel upon receiving a signal from said input device.

### Claim 3 (depends on 1)

The hands-free voltage task lighting system for medical procedures set forth in claim 1 wherein said light source comprises,
at least one high intensity illumination LED in communication with said power source from said control module.

### Claim 4 (depends on 1)

The hands-free variable task lighting system for medical procedures set forth in claim 1 wherein said light assembly comprises, said light source and said smart glass panel positioned within a housing having a closed base and an oppositely disposed open apertured lens mount with a transparent focusing lens secured within.

### Claim 5 (depends on 1)

The hands-free variable task lighting system for medical procedures set forth in claim 1 wherein said smart glass panel optical transparency response to varied voltage comprises,
increase in optical transparency by controlled voltage applied to said smart glass panel and reduced optical transparency when no controlled voltage is applied to said smart glass panel.

### Claim 6

An adaptable lighting control system for existing hands-free task lighting systems comprises,
a control module having a source of power, a light control attachment having a housing adapted to said task lighting system, a selective activated smart glass panel within said housing in optical alignment with said task lighting system optical output and in communication with said control module remotely.

### Claim 7 (depends on 6)

The adaptable lighting control system for existing task lighting system set forth in claim 6 wherein said smart glass panel optical transparency increases with applied voltage from said control module and absent of controlled voltage.
