Definitions

  • This invention relates to a high-intensity lamp of the type utilizing a physically small, low-voltage, incandescent lamp bulb together with a transformer for connecting the lamp bulb to a commercial source of electrical energy.
  • Lamps of this general character have become increasingly popular for use as student desk lamps primarily on account of compactness of design permitted by the small size lamp bulb.
  • a small reflector can be used in conjunction with such lamp bulb to achieve a concentrated light beam and thus the efficient illumination of a book or other small object.
  • the primary object of this invention is to provide a high-intensity lamp of this character which requires very little supporting area on a desk or other surface.
  • the lamp comprises a pair of generally cylindrical parts, one a base housing the transformer, and the other, a reflector housing movable from a juxtaposed closed position with respect to the base to a wide variety of operative positions above and laterally beyond the base.
  • Another object of this invention is to provide a compact lamp of this character capable of use as a night light.
  • the reflector housing is provided with a translucent rim that forms the only aperture for efliuent light when the cylindrical parts are closed.
  • Switching means connects the lamp bulb to a low-voltage tap of the transformer.
  • Another object of this invention is to provide an improved switching assembly for a high-intensity lamp of this character the actuator of which is inconspicuous, yet readily accessible for manipulation, and even when the lamp parts are closed.
  • a radio-type selector switch that is quite adequate for low-voltage switching, and accommodated in the top of the base part, the switch having the conventional shaft for cooperation with a knob actuator.
  • a disc is provided that not only provides the aperture for coupling to the switch shaft, but which also neatly closes the top of the base part.
  • the rim of the discrclosure is accesible for manipulation substantially equally from any lateral approach.
  • Another object of this invention is to provide a lamp of this character capable of use as a flood light.
  • the cylindrical reflector housing is so mounted that it may be inverted while yet in juxtaposed relationship with the base part. Accordingly, the reflector directs a light beam upwardly for reflection from the ceiling, whereby broad illumination is obtained.
  • Another object of this invention is to provide a lamp of this character that is capable of use as a search light
  • the lamp assembled with the reflector housing inverted, can :be grasped conveniently by the base, and the beam can be directed as desired by the user.
  • Still another object of this invention is to provide a lamp of this character that can be used as a wall lamp to provide spot illumination for any desired purpose, as
  • a wall-hung art object for example a wall-hung art object or as: a bed reading lamp.
  • Another object of this invention is to provide a stabilizing foot and unique case elements for retractably receiving it, and swingably mounting it to project from either side, the foot also serving conveniently as a means detachably cooperable with a wall bracket for thus mounting the lamp.
  • Another object of this invention is to provide improved suction cup for stabilizing the base, and which nevertheless allows the lamp to be attached to a wall.
  • the suction cup is formed as an annulus, whereby a suspension device may cooperate with an aperture located in the ring.
  • FIG. 1 is a side elevational view of a lamp incorporating the present invention, and shown in use as a desk lamp;
  • FIG. 2 is a bottom plan view thereof

  • the aperture 40 is precisely located midway of the height of the housing 12 which allows the housing 12 to be inverted relative to the base housing 10 for purposes hereinafter to be described.
  • a third hinge 42 has one channel-shaped lea-f 44 pressfitted in the opposite end of the shorter arm 24.
  • the other leaf of the hinge 42 is in the form of a bracket 46 that serves as a means for mounting the arms 24, 22 and the reflector housing 12 on the base housing 10.

Leads from the switch 92 and the transformer windings extend through the lateral aperture 48 in the housing 19 and thence are threaded through the hollow arms 24 and 22 and through the hollow pin 38 into the reflector housing 12 for connection to the lamp socket 54.
  • knob 18 Closing the top of the base housing 10 is the knob 18.
