Abstract
A lamp employs a halogen light fixture which includes a fitting threadably engaging a conduit entry "L". A standard electrical cord is provided to the entry "L" and connects inside the entry "L" with the pigtail wiring of the light fixture. The entry "L" also receives a spring clamp, securely mounted thereon, for enabling the lamp to mount to a support via use of the spring clamp, for providing a work lamp on a temporary or semi-permanent basis at a work site.
Claims52
A lamp, comprising:
- a halogen light fixture;
- a clamp connected to said halogen light fixture, said clamp having two pivotally-connected jaws forced toward one another by spring tension and a handle for spreading said jaws, said clamp extending away from said halogen light fixture;
- an electrical connection housing associated with said halogen light fixture;
- halogen light source wires extending out of said halogen light fixture into said electrical connection housing for supplying electricity to said halogen light source;
- and
- an electrical power cord having power cord wires therein for connecting said lamp to a power source, said power cord wires being connected to said halogen light source wires within said electrical connection housing.
3 more elements
A lamp, comprising:
- a light fixture, having a cavity therein for housing a light so opening in said fixture to said cavity;
- a guard disposed over said opening;
- and
- a clamp connected to said light fixture, said clamp having two jaws forced toward one another by spring tension, a first of said two clamp jaws being rigid and connected to said light fixture such that there are a plurality of orthogonal pivot axes there being only one pivot axis for each pivot direction, and the second of said two clamp jaws being pivotally connected at a first pivot point to said first clamp jaw, said clamp further including a spring connected to said first and second clamp jaws and a handle for spreading said jaws.

4 more elements
A lamp, comprising:
- a halogen light fixture, having a cavity therein for housing a light source and having an opening in said halogen light fixture to said cavity;
- a support member having a first end, a second end and an elongate axis and being pivotally-connected at a first pivot point at said first end to said light fixture, said first pivot point having a pivot axis substantially perpendicular to said elongate axis of said support member;
- and
- a clamp connected to said support member at said second end thereof, said clamp having two jaws forced toward one another by spring tension, a first of said two clamp jaws being fixedly connected to said support member and the second of said two clamp jaws being pivotally connected at a second pivot point to said first clamp jaw, said clamp further including a spring connected to said first and second clamp jaws to force said two clamp jaws together and a handle connected to said second of said two clamp jaws at said second pivot point.
1 more element
A lamp, comprising:
- a light fixture, having a cavity therein for housing a light source and having an opening in said fixture to said cavity;
- a substantially rigid support member having a first end and a second end and being connected at said first end to said light fixture;
- and
- a clamp connected to said support member at said second end thereof, said clamp having two jaws, said support member and one of said two clamp jaws having respective elongate axes extending in substantially the same dimension, one of said clamp jaws having an elongate axis and two lateral axes, said elongate and lateral axes being substantially perpendicular to one another, said clamp jaws opening substantially along a first of said two lateral axes, the width of at least one of said two clamp jaws along the second of said two lateral axes inhibiting rotation of said clamp about said elongate axis.
1 more element
A lamp, comprising:
- a halogen light fixture;
- an elongate support member having a first end, a second end and an elongate dimension, said support member being substantially rigid in said elongate dimension, said first end being connected to said halogen light fixture;
- and
- a clamp connected to said second end of said elongate support member, said clamp having two jaws forced toward one another by spring tension and a handle for spreading said jaws, said clamp being fixedly connected to said elongate support member so as to ensure that said jaws extend away from said second end of said elongate support member substantially along said elongate dimension of said elongate support member.
1 more element
A lamp, comprising:
- a light fixture;
- an elongate, substantially rigid support member having a first end, a second end and an elongate dimension and being connected at said first end to said light fixture;
- and
- a clamp connected to said light fixture, said clamp having two jaws forced toward one another by spring tension, a first of said two clamp jaws being fixedly connected to said support member so as to ensure that said first of two clamp jaws extends away from said elongate support member substantially along said elongate dimension, and the second of said two clamp jaws being pivotally connected to said first clamp jaw, said clamp further including a spring connected to said first and second clamp jaws and a handle for spreading said jaws.
1 more element
A lamp, comprising:
- a substantially rigid halogen light fixture having a cavity therein for housing a halogen light source and having an opening in said fixture to said cavity;
- and
- a clamp connected to said halogen light fixture at a position on said halogen light fixture, said position substantially establishing the center of a spherical coordinate system as to ensure that said jaws extend away from said position in a substantially radial direction, said clamp having two jaws forced toward one another by spring tension and a handle for spreading said jaws, said clamp being connected and said handle being spaced from said halogen light fixture so that said handle can be grasped without touching said halogen light fixture.
A lamp, comprising:
- a halogen light fixture, adapted for receiving a halogen light bulb, and having a light transmissive cover and a protective guard over said cover;
- an electric power cord adapted to connect said halogen light fixture to an electric power source;
- an elongate support member having a first end, a second end and an elongate dimension, said support member being substantially rigid in said elongate dimension, said first end being connected to said halogen light fixture;
- and
- a clamp connected to said second end of said elongate support member, said clamp having two jaws pivotally attached to one another intermediate their ends and a spring for forcing said jaws toward one another at one end thereof, the other end of said jaws forming a handle for spreading said jaws, said clamp being connected so as to ensure that said clamp jaws extend away from said second end of said elongate support member, and said elongate support member being sufficiently long to ensure that said handle clears said halogen light fixture.
