Claim:
1. A welding helmet with a sensor-operated light and photochromic visor lens comprising: a welding helmet body having a front side, a rear side, a right side, a left side, a top side, and a bottom side, wherein the welding helmet body is configured, sized, and shaped to cover and generally conform to a welder's face; a frustoconical protrusion integrated into the front side in a central position proximal the top side, the protrusion having an upper side extending from the front side at an angle in a range of 90 degrees to 145 degrees relative to the front side proximal the top side, the protrusion further having a forward side, and an L-shaped lower side opposite the upper side of the protrusion, the forward side disposed at a right angle relative to the upper side, the lower side directed from a lower end of the forward side to the front side of the welding helmet body; a battery-operated light emitting diode light bulb integrated into the front side of the welding helmet body within the protrusion; at least one photosensor disposed on the front side of the welding helmet body proximal the protrusion; a transparent covering disposed over the forward side of the protrusion, wherein the transparent covering is configured to protect the light bulb; a battery compartment disposed on the rear side of the welding helmet body proximal the protrusion, wherein the battery compartment is configured to house at least one battery; an on-off switch disposed on the rear side of the welding helmet body proximal the battery compartment; a housing disposed on the rear side of the welding helmet body proximal the battery compartment and the on-off switch; a microchip disposed within the housing, the microchip, the on-off switch, the at least one battery, the light bulb, and the photosensor being in operational communication with each other; an auto-darkening filtered visor lens centrally disposed in the front side of the welding helmet body, the visor lens having an upper side, a lower side, a first side, and a second side opposite the first side, each of the first side and the second side being disposed proximal to the respective right side and left side of the front side of the welding helmet body, the visor lens in operational communication with the at least one photosensor, wherein the visor lens darkens automatically upon detection by the at least one photosensor of a welding arc; a length-adjustable strap disposed across the rear side of the welding helmet body, the strap having a pair of outer ends, the strap extending from the right side to the left side proximal the upper side of the visor lens; wherein upon the detection of a welding arc by the at least one photosensor, the visor lens darkens automatically and the light bulb is activated when the on-off switch is also in an “on” position.
