  • Patent number: 4543623
    Abstract: A light fixture for underwater use in swimming pools has a waterproof gasket between the lens and the housing enclosing the electrical components. The gasket is fabricated of an off-white, neoprene material and is devoid of any coloring agents, such as carbon black, which are subject to leaching by chlorine-containing water in the pool. As a result, discoloration of the wall of the pool and also of the lens will not occur, even where chlorine concentrations are relatively high.

    Abstract: A variable-width-beam light apparatus is provided having a lamp and reflector assembly in which a lamp is supported for selective axial displacement along a longitudinal optical axis with respect to a focal point of the reflector to enable adjustment in the width or angle of divergence of an emitted beam of light. The lamp is selectively positioned by a rotatable knob carried by a lens of the assembly and positioned exteriorly at the front of the lens for operation. The rotatable knob connects with a shaft coupled by screw threads with a lamp engaging cylinder that is axially slideable in a tubular guideway such that rotational movement is translated to longitudinal movement to effect and control axial displacement of a lamp. The lamp is resiliently biased in a forward direction with respect to the lens.

A bulb is supported in fixed relation to the body, and a reflector is supported in fixed relation to the head. Rotation of the head changes its longitudinal position relative to the body, hence moving the reflector either forwardly or rearwardly relative to the bulb and thereby adjusting the focus of the flashlight beam.In order to retain the selected focus adjustment, an expansible spring is disposed partly inside the flashlight body and partly inside the flashlight head, the corresponding ends of the spring being seated in respective ones of those members. The expansive force of the spring biases the interengaging threads of the flashlight head and body, producing a substantial frictional force so as to retain the desired rotational position of the head.

  • Patent number: 4387417
    Abstract: A retaining means for a lamp within a luminaire provides structural support and positive positioning. It comprises a resilient wire formed to a four-sided parallelogram shape with four outboard reverting projections between segments. One pair of diametrically opposed projections encircle bolts which hold the retainer transversely to the lamp axis at the rim of the socket compartment. Another pair of projections are unrestrained and provide extra flexibility in accommodating to variations in lamp diameters.

  • Patent number: 4385345
    Abstract: A vehicle headlamp in which an optical unit for a sealed beam is mounted between a carrier ring fixed to the vehicle and a removable cap ring. On the carrier ring two diametrically opposed pins are supported in bearing bushes to be coaxially rotatable and axially displaceable. Both pins are fixed to a resilient clip that bears on cam faces on the outer ends of the bushes. Upon pivoting the clip, the pins are jointly rotated and, by the action of the cam faces are axially oppositely displaced. As they are extended outwards they engage recesses in the cap ring to secure it to the carrier ring. Eccentric portions on the outer ends of the pins thereupon bear on the recesses with further rotation of the pins to draw the cap ring and carrier ring together to grip firmly an interposed rim of the optical unit.

  • Patent number: 4384319
    Abstract: A projection lighting unit which includes a U-shaped bracket member having an apertured faceplate and a rear upstanding wall, a glass reflector secured to the bracket's faceplate portion and including a concave reflecting portion and a rear neck portion adjacent thereto and including a cylindrical opening therein, a capsule member removably positioned within the reflector's rear opening and including an incandescent projection lamp (e.g., tungsten-halogen) and a cylindrical, metallic base member secured to the sealed end of the lamp, and a biasing flange member including a pair of cam springs which slidably engage the upstanding rear wall of the bracket during rotational insertion of the lamp capsule within the unit's reflector. The unit thus provides for rear removal of the lamp capsule from the glass reflector and bracket components.

  • Patent number: 4376967
    Abstract: An improved projection unit which enables front removal of the unit's tungsten halogen projection lamp from the unit's glass reflector. A first retention member in the form of a boxlike metallic "can" is secured to the lamp's press sealed end and held in place by a wireform which pivots to engage a planar back surface of the glass reflector to provide said securement. The wireform is positioned on the boxlike "can" and can be inserted through the reflector's rear opening during lamp positioning.

  • Patent number: 4360859
    Abstract: A boat light includes a shield recessed within the hull of a vessel. A conventional sealed beam head-lamp unit seats in an exteriorly spherically shaped lamp unit retaining member formed of a resiliently flexible soft material such as rubber. The retaining member and shield have mating spherically shaped surfaces so that the retaining member can be angularly adjusted, within a pre-determined, limited range, to any of various selected positions within the shield, thus to correspondingly adjust and hence correctly aim, the head-lamp unit. The retaining member is quickly and firmly secured, in each position to which it is adjusted, through the provision of a soft rubber mounting ring, which fits over the inner end of the shield, and is spherically shaped interiorly thereof, to form a ball-and-socket mounting cooperating with the shield and the retaining member.

  • Patent number: 4356539
    Abstract: This invention relates to polymer sealed beam headlamp units and more particularly to a mounting assembly for securing these headlamp units to vehicles. The assembly includes a headlamp having a plurality of mounting blocks integral with and mediately articulated from the reflector portion of the lamp envelope. The mounting blocks project outwardly from the exterior surface of the envelope and reference the lamp beam through the envelope reflector. The mounting blocks have openings for receiving and engaging fasteners therein for securing the headlamp to a vehicle. The fasteners are inserted in the blocks and adjusted relative thereto to referentially relate the lamp alignment to the vehicle. The fasteners are resiliently biased by buggy springs which at least partially surround the fastener. The non-attached head of the fastener is inserted within a slotted vehicle panel and is tensionally secured thereto by the buggy springs.

  • Patent number: 4345307
    Abstract: A retainer assembly for a rectangular vehicle headlamp consisting basically of a one-piece rubber molding having an outer base member and a rectangular lamp support pivotally supported on the base member by an integral web portion extending horizontally between the base to the top of the rectangular lamp support approximately midway along its axial length. This arrangement permits pivotal movement of the lamp support portion with respect to the base about a horizontal axis for adjusting the angular position of the headlamp and also providing an excellent vibration and shock mount for the lamp with respect to the associated vehicle. An adjusting assembly at the lower part of the lamp support portion provides the necessary headlamp adjustment. A metal frame is connected to the base portion and provides the rigidity necessary to fasten the retainer assembly and headlamp therein onto the vehicle body.In one embodiment the base member is rectangular in configuration and has a metal insert molded frame for support.

  • Patent number: 4339790
    Abstract: Improved positioning means are provided to locate a light source at the focus of a parabolic aluminized reflector (PAR) lamp and, in particular to improved positioning means which center said light source in the plastic reflector of a PAR lamp and preferably an all plastic PAR lamp. The preferred mount construction being employed utilizes a plastic block having mating parts which define a cavity from which lead wires extend and which is filled with an elastomeric polymer providing both a leak-proof seal around the lead wires as well as a more reliable barrier to moisture leakage through the mount assembly. The improved positioning means can be rib elements located in the receptacle means on said reflector to which said plastic mount is joined.
