Collapsible light
View Patent ↗A collapsible lighting device has a main body surrounded by a collar whose position is adjustable along the longitudinal axis of the main body. Pivotally connected or hinged legs are attached to the collar and to the main body with struts. When the collar is on one position, the legs deploy outward from the main body to the extent permitted by the struts, thereby allowing the legs to support the collapsible lighting device upright. A lamp head is attached to a member which telescope from the main body. When deployed, the lamp head can be switched on to provide illumination. When the collar is another position, the legs are drawn in toward the main body to form a cylindrical shape. The lam head can be positioned so that when the telescoping member is retracted into the main body, the collar surrounds the exterior of the lamp head, thus protecting the lamp head for transport. The overall cylindrical shape of the lighting device in the collapsed position facilitates transport, for example using a strap to carry the device on one's back.
1. A collapsible lighting device comprising:
(a) a main body:
(b) a telescoping member adjustable to a position within said main body;
(c) a lamp head positioned at a first end of said telescoping member, said lamp head having sockets for illuminating elements;
(d) an electrical connection to provide a connection between said lamp head and a power source; and
(e) a collar surrounding said main body, said collar being adjustable to a first collar position relative to said main body when said lighting device is in a deployed position, and to a second collar position relative to said main body when said lighting device is in a collapsed position;
wherein said collar is adjustable to a position to enclose exterior side surfaces of said lamp head when said lighting device is in said collapsed position.
2. The collapsible lighting device recited in claim 1 , comprising:
a leg pivotally connected to said collar and to said main body to support said lighting device in said deployed position.
3. The collapsible lighting device recited in claim 2 , wherein said collar adjusts to said first collar position when said leg is in a first leg position to support said lighting device in said deployed position and said adjusts to said second collar position when said leg is in a second leg position.
4. The collapsible lighting device recited in claim 3 , said collar having hand grips therein, said hand grips allowing adjustment of said collar to said first collar position and said second collar position.
5. The collapsible lighting device recited in claim 4 , said collar having an opening wider than a diameter of said main body.
6. The collapsible lighting device recited in claim 5 , comprising:
a pivoting connection between said lamp head and said telescoping member.
7. The collapsible lighting device recited in claim 6 , wherein said pivoting connection between said lamp head and said telescoping member comprises a hinge joint.
8. The collapsible lighting device recited in claim 7 , said lamp head comprising a plurality of illuminating elements.
9. The collapsible lighting device recited in claim 8 , said illuminating elements comprising at least one of a light emitting diode, an incandescent bulb, a fluorescent bulb, and a halogen bulb.
10. The collapsible lighting device recited in claim 9 , said switch comprising an indicator to indicate a state of power available from said power source.
11. The collapsible lighting device recited in claim 9 , comprising:
a switch configured to activate at least one of said illuminating elements.
12. The collapsible lighting device recited in claim 11 , wherein said switch activates each of said illuminating elements in a sequence.
13. The collapsible lighting device recited in claim 11 , wherein said switch comprises a continuously variable switch.
14. The collapsible lighting device recited in claim 1 , said power source comprising a battery.
15. The collapsible lighting device recited in claim 14 , said battery comprising a rechargeable battery.
16. The collapsible lighting device recited in claim 14 , comprising:
battery recharging circuits.
17. The collapsible lighting device recited in claim 1 , wherein said lighting device is configured to collapse to a substantially cylindrical shape.
18. The collapsible lighting device recited in claim 17 , comprising:
a shoulder strap for carrying said lighting device when in said collapsed position.
19. A lighting device comprising:
(a) a main body;
(b) a lamp head having sockets therein for illuminating elements;
(c) an electrical connection to provide a connection between a power source and said lamp head;
(d) a collar surrounding said main body, said collar being moveable relative to said main body; and
(e) a plurality of legs adjustably connected to said collar such that a position of said legs determines a position of said collar, said legs configured to support said lighting device in an upright position;
wherein said collar is adjustable to a position to enclose exterior side surfaces of said lamp head when said legs are in a collapsed position.
