Abstract

A light head is mounted on a common base, and includes a light source in a mounting base. The base is mounted on a collapsible elongated pole, and the pole is for mounting on an outside wall of a carrying case. There is a carrying handle for the case, an electrical power outlet mounted on a wall, base or lid of the case and for plugging in an electrical wire to power the light head. The interior of the case is for locating a rechargeable battery, and the battery when charged, supplies power to the power outlet such that the light head can be powered. Recharging can be via either a 12V DC automobile or a 110 AC power supply. The carrying handle is extendible; and retractable, and in the retraction mode is essentially within the general perimeter space of the case. The case includes a pair of pulley wheels, the wheels being for facilitating the moving of the case.

Claims

1. A system for providing lighting comprising a light head mounted on a common base, the light head including a light source in a mounting base, the base being mounted on a collapsible elongated pole, the pole being for mounting on an outside wall of a carrying case, the carrying case being for locating the light head and collapsible pole when the light is not in use, a carrying handle for the case, an electrical power outlet mounted on a wall of the case and being for plugging in an electrical wire to power the light head, the interior of the case being for locating a rechargeable battery, and the battery being, when charged, for supplying power to the power outlet such that the light head can be powered, wherein the light source in the mounting base includes a light head with a panel of multiple LEDs mounted to a heat sink and wherein the heat sink is exposed to an ambient environment.

2. A system as claimed in claim 1 wherein the pole has components which are telescopic relative to each other such that the pole can be extended or collapsed and selectively locked at different degrees of extension, and in the collapsed state is locatable in an interior portion of the case.

3. A system as claimed in claim 1 including at least one connector element, the connector element being for securing the pole to the outside of the case.

4. A system as claimed in claim 1 including at least one connector element, the connector element being for securing the light head to the top of the pole.

5. A system as claimed in claim 1 including a second connector element, the second connector element being for securing the light head to the top of the pole.

6. A system as claimed in claim 1 wherein the carrying handle is extendible;

and retractable, and in the retraction mode is essentially within the general perimeter space of the case.

7. A system as claimed in claim 1 wherein the case includes a pair of pulley wheels, the wheels being for facilitating the moving of the case.

8. A system as claimed in claim 1 wherein the heat sink is a cast aluminum heat sink.

9. A system as claimed in claim 1 wherein the light source is mounted on an extension telescopic pole which mounts on to the wall, lid or case of a case, and wherein inside the case there is a battery and charger which is chargeable via either a 12V DC automobile or a 110 AC power supply.

10. A system as claimed in claim 1 wherein the panel of LEDs is an articulating light panel, and wherein a wall, lid or base of the case includes a single or multiple power outlet sockets, and wherein the case is formed of a relatively water and dust resistant plastic, ad wherein a seal is provided between movable components of the case to facilitate this resistance.

11. A system as claimed in claim 10 wherein the case includes wheels and an extension handle to facilitate movement of the case.

12. A system as claimed in claim 10 wherein the case includes bays, each bay being formed for receiving a light or other components of the light.

13. A system for providing lighting comprising a light head mounted on a common base, the light head including a light source in a mounting base, the base being mounted on a collapsible elongated pole, the pole being for mounting on an outside wall of a carrying case, the carrying case being for locating the light head and collapsible pole when the light is not in use, a carrying handle for the case, an electrical power outlet mounted on a wall of the case and being for plugging in an electrical wire to power the light head, the interior of the case being for locating a rechargeable battery, and the battery being, when charged, for supplying power to the power outlet such that the light head can be powered, wherein the light source in the mounting base includes a light head with a panel of multiple LEDs mounted to a heat sink and wherein the heat sink includes fins.

14. A system as claimed in claim 13 wherein the carrying handle is extendible;

and retractable, and in the retraction mode is essentially within the general perimeter space of the case.

15. A system as claimed in claim 14 wherein the case includes a pair of pulley wheels, the wheels being for facilitating the moving of the case, the pole having components which are telescopic relative to each other such that the pole can be extended or collapsed and selectively locked at different degrees of extension, and in the collapsed state is locatable in an interior portion of the case, and including at least one connector element, the connector element being for securing the pole to outside of the case.

16. A system as claimed in claim 13 wherein the heat sink is a cast aluminum heat sink.

17. A system as claimed in claim 13 wherein the light source is mounted on an extension telescopic pole which mounts on to the wall, lid or case of a case, and wherein inside the case there is a battery and charger which is chargeable via either a 12V DC automobile or a 110 AC power supply.

18. A system as claimed in claim 13 wherein the panel of LEDs is an articulating light panel, and wherein a wall, lid or base of the case includes a single or multiple power outlet sockets, and wherein the case is formed of a relatively water and dust resistant plastic, ad wherein a seal is provided between movable components of the case to facilitate this resistance.
