Abstract: A light assembly coupled to a spray gun for spraying electrostatically charged coating material is disclosed. The spray gun includes a gun body comprising a barrel, a nozzle assembly extending from the barrel in a longitudinal direction, a voltage multiplier, and an actuator assembly configured to transition the voltage multiplier between an activated state and a deactivated state. The light assembly includes a light and circuitry electrically connected to the light. The circuitry is configured to supply electrical energy inductively obtained by the circuitry to the light when the voltage multiplier is in the activated state. The light assembly can also include a housing, a lens cover releasably attached to the housing, and a control member for changing a characteristic of the light.

Abstract: A system and method for shaping and/or directing a spray stream includes electrostatically charging a spray stream by exposing fluid to be sprayed to an electrical field within a fluid sprayer to create an electrostatically charged spray stream, and then creating an electrical field between secondary electrodes externally to the fluid sprayer such that the electrostatically spray stream is shaped and/or redirected as it passes through the electrical field.

Abstract: An electrostatic painting device capable of reducing any AC or electromagnetic emissions when the device is powered on is provided. The emissions affect electronic components present during painting of various objects or even when the device is powered on. The electromagnetic induction into the conductive circuit elements in turn induces voltages and currents, which potentially harm the micro-electronic circuits. One such device includes a choke between a fluid tip and a high voltage source of the device to reduce these emissions. The voltage source may include at least one capacitor which supplies the AC emissions representing electromagnetic emissions risk during the discharge of paint from the device. The choke connected to the voltage source substantially reduces the emissions involved during the paint discharge, while allowing the discharge of electrons, thereby imparting negative DC charge to the paint and the workpiece, and preventing damage to electronic circuits during the process.

Abstract: A size-selective aerosol nozzle that includes an impactor body with an internal enclosed sidewall spanning in a directional longitudinally from a distal end of a distal spray end to a central sidewall terminal end and defining a central spray channel and a fluid segregation member. The segregation member may include an internal enclosed sidewall defining at least one liquid removal channel spanning laterally away from a central spray channel, defining a second aerosol discharge outlet in fluid communication with the central spray channel, and spans into the central spray channel to bifurcate the central spray channel into the liquid removal channel and an aerosol discharge channel. The fluid segregation member has an inner surface defining the liquid removal channel and is in an overlapping configuration with the internal enclosed sidewall to mechanically segregate emitted aerosol spray from the first aerosol discharge outlet of a portable hand-held aerosol spray assembly.
