Abstract

A UV curing lamp (18) has variable resistive ballast (Fig. 6A) provided by at least one resistance alloy wire. The variable resistance ballast defines the lamp's maximum operating power consistent with the power supply. The wire in combination with a fan also doubles as thermal ballast provided by air flowing across the wire onto the UV lamp. A detachable reflector (21) in a generally parabolic cylinder shape directs light from the lamp located on the reflector's focal axis. The curing lamp with resistive ballast can be in the form of a handheld unit (11) or as a floor unit (Fig. 8) with rotating lamps within the housing.

Abstract

A UV curing lamp has variable resistive ballast provided by at least one resistance alloy wire and a set of switches tapping varying positions along the resistance alloy wire. The variable resistance ballast defines the lamp's maximum operating power consistent with the power supply. The wire in combination with a fan also doubles as thermal ballast provided by air flowing across the wire onto the UV lamp. A detachable reflector in a generally parabolic cylinder shape directs light from the lamp located on the reflector's focal axis. The curing lamp with resistive ballast can be in the form of a handheld unit or as a floor unit with rotating lamps within the housing.

Abstract

A moveable machine to rapidly apply and cure thin layers of a UV curable coating on a surface such as a floor. The machine has an applicator to apply a thin curable coating in a path following the direction of motion of the machine. The machine also has UV lamps to cure the curable coating with a curing beam that overlaps newly applied coating. The UV lamps emit an intense UV radiation beam creating an annular cure zone around the applicator path. Movement of the machine along with the ensuing movement of the applicator and rotating UV lamps causes the applied curable coating to be exposed to the annular cure zone and cured. This rapid curing of applicator coating paths allows the machine to be immediately passed over the cured area multiple times and rapidly build up multiple thin cured layers to achieve a thick coating.

Abstract

A machine (11) for applying ultraviolet light to curable coatings on floors and other wide area surfaces. A housing (13) encloses rotating arms {16, 17, 18, 19) carrying UV lamps (61, 63) spinning about a central axis (25). Rotation is caused by reactive momentum from heated air jets coming from fans in barrels (35, 36, 37, 38} blowing air over heated wires, resembling hand held hair dryers, with the barrels supported under rotating arras. The heated wires are ballast (91) for the lamps, providing thermal and electrical stability. The rotating lamps cover an annular pattern which, when advanced forwardly, becomes a linear- swath, almost as wide as the housing. A floor, or similar surface, can be cured in a few minutes.

Abstract

A UV lamp and beam generator (11) has resistive ballast (29) provided by a glowing wire and thermal ballast provided by heated air (A), coming via the same hot wire. A detachable reflector housing (17) has curved symmetric spars (54,56) in a generally parabolic shape defining an axis with an elongated axially lamp (18) at a focal line. Heated air flows through the spars heating the lamp in a start mode and cooling the lamp in a run mode. The lamp and beam generator is made from electrical components found in a household hair dryer including a housing (12) and a trigger switch (19) with the housing having a body portion 15 containing electrical ballast components.
