Abstract: A modular ballast system particularly suited for strip lighting installations has ballast modules on opposite ends of each fluorescent lamp tube, each module having lamp connectors for receiving the end pins of the fluorescent lamp, capacitance and inductance elements connected to the lamp connectors in each module, and jumper conductors interconnecting the capacitance and inductance elements of the modules to define a bridge type ballast circuit for powering the fluorescent lamp. Each ballast module can be made small and lightweight with a single inductor and capacitor forming two legs of a four leg bridge type ballast. Pairs of ballast modules can be connected back-to-back to transmit electrical power without external wiring to successive fluorescent lamps along the strip.

Abstract: A lighting fixture includes a housing and a reflector assembly in the housing seated in a split, resilient seating ring and retained by a resilient retaining clip. The axial position of a reflector assembly may be adjusted by moving the seating ring axially. The ends of the ring on opposite sides of the split can be squeezed to resiliently disengage the ring from its interference-fit with the housing wall. The user squeezes the ring in this manner while moving it to a desired location in the housing and then releases it. The angular position of the reflector assembly may also be adjusted. The user squeezes the clip to resiliently disengage it from its interference-fit with the housing wall. The user squeezes the clip in this manner while pivoting the reflector assembly. With the ring abutting the reflector, the user then releases the clip to resiliently re-engage the housing wall. The lighting fixture may include a spike for securing the fixture in the ground.

Abstract: An apparatus and method for curing radiation curable material includes a lamp unit providing radiation in a converging beam directed toward a focal plane and forming a curing zone at a curing position for receiving the curable material. The lamp unit is mounted in a boot member having a spiral external thread for engaging a spiral internal thread on the wall of a housing chamber for receiving the boot member. The engagement of the threads is such that rotation of the boot member controllably varies the intensity of radiation in the curing zone by changing the distance between the radiation outlet of the lamp unit and the curing position. The curing zone may be an elongated band such that rotation of the boot member also provides angular adjustment of the elongated band relative to a curing path for the curable material. The boot member may include internal cooling passages and these passages may contain overlapping light baffles blocking the escape of harmful radiation.

Abstract: A scanning light source system for projecting onto each area of a complete painting or other planar subject a beam of light and for moving said beam vertically and horizontally. The vertical movements comprise a succession of sweeps across the painting for the purpose of consecutively illuminating each part of the painting sufficiently strongly so that the whole may be photographically reproduced more satisfactorily than has been possible heretofore, i.e. through the use in combination of Kodak #6121 duplicating film or another gamma 1.0 film, polarizing filters, and a lens aperture of f22 or smaller. The horizontal movements position the light source for each vertical sweep. Said system enables a beam of light to be projected onto each part of the entire surface of the subject painting at an angle of greater than 40.degree. and less than 80.degree., thereby enabling brush-stroke and texture detail of a painting to be accurately rendered in a photographic reproduction.

Abstract: A hanger on which one or a plurality of electric lamps is slidably positionable along an elongated housing having non-electrified rails. The hanger includes a different resiliently extensible helical electrical cord to supply electric power to each lamp. Each helical cord is longitudinally disposed within the housing; when there is more than one lamp, the helical cords of the additional lamps are each disposed in a separate container within the housing to prevent entanglement of the cords when the positions of the lamps are adjusted. The helical cords in their relaxed positions have a diameter greater than the width of a slot in the housing so that the helical cord cannot protrude or fall from the housing. The present hanger allows installation of the unit without the services of an electrician, and because the lamps can slide on the rails, the position of each lamp is fully adjustable longitudinally of the housing.
