    摘要: An improved projection unit including a glass reflector and a capsule member (tungsten halogen lamp and metallic retention member) removably positioned within the reflector. The projecting end of the metal retention member is threaded only on two sides and adapted for having a single thread annular nut positioned thereon to retain the capsule securely within the reflector. The nut is resilient to assure that damage to the reflector, boxlike members, or nut itself is prevented, and also to compensate for thermal expansion.

    摘要: A projection lighting unit which enables dual insertion of the unit's glass reflector therein. The reflector, having a tungsten-halogen projection lamp sealed therein, can be inserted in a vertical manner (and therefore parallel to the plane of the unit's faceplate) or it can be inserted horizontally (or perpendicular to the planar faceplate). The means of grasping and retaining the reflector within the unit's lampholder assembly preferably comprises a steel wireform having two deflectable segments (or elements) which deflect outwardly when engaged by the reflector. Removal of the reflector is possible in similar but reverse fashion.

    摘要: A protective shield for an ultraviolet-emitting fluorescent lamp comprising a tubular sleeve coaxially surrounding the lamp envelope and formed of a plastic material, such as a fluorocarbon resin of a fluorinated ethylene-propylene, which has a spectral transmittance of at least about 80 percent of the ultraviolet radiation emitted from the lamp over the wavelength range from about 320 to 400 nanometers and substantially maintains such transmittance, along with mechanical integrity, after at least about 1000 hours of lamp operation.

    摘要: A plug-in lamp assembly for use as a picture element in an information display screen includes a plurality of low-pressure arc discharge lamps for selectively generating multiple colors, a lamp plug for interconnection and mounting of the discharge lamps, and a lamp socket for plug-in attachment of the lamp plug. Each discharge lamp has electrical leads extending from a first end thereof and a light output region at a second end thereof. The lamp plug comprises a base having spaced-apart electrical connector pins and a cap attached to the base. The first ends of the discharge lamps extend through openings in the top wall of the cap into the lamp plug, and selected electrical leads are coupled to the electrical connector pins. The lamp plug and the lamp socket include openings for directing cooling air over the first ends of the discharge lamps. The cooling air is preferably directed from the rear of the display screen through the lamp socket and the lamp plug and is exhausted through the front of the display screen. The lamp socket preferably includes an upstanding locating projection and a spring clip for retaining the lamp plug.

    摘要: An improved projection unit including a glass reflector having a forward reflecting portion which includes an internal substantially concave reflecting surface and an apex portion with an opening therein. An incandescent lamp is oriented such that its envelope portion is arranged relative to the reflecting surface of the reflector and its sealed end portion having a pair of spaced apart lead-in wires projecting therefrom is arranged within the reflector's opening. An electrically insulative cap member is fixedly secured to an external surface of a glass reflector immediately adjacent the reflector's rear opening. The cap member includes a pair of contacts spacedly located therein, each of these contacts being joined electrically to a respective one of the projecting lead-in wires from the incandescent lamp. In a further embodiment of the invention, a holder is provided for providing electrical connection between the projection system's circuitry and the incandescent lamp.

    摘要: A projection unit for use within a slide or film projector, or a microfilm viewer. The unit comprises an electrically insulative holder, a socket forming part of the holder's rear upstanding segment, a glass reflector secured to the holder's front segment such that its forward aperture aligns with an opening in the front segment, a tungsten-halogen lamp removably located within the socket and not engaging any of the interior surfaces of the reflector, and a slidable ejector (e.g., elongated bar member) for engaging the sealed end of the lamp and ejecting it out through the glass reflector's forward opening. Replacement of the lamp is thus possible without replacing the glass reflector. In addition, the invention maintains constant referencing characteristics to thereby enable successive, similar lamps to be precisely oriented within the reflector without the need for a prefocusing operation.
