DETAILED DESCRIPTION OF THE EMBODIMENTS

(8) This device is intended to be a portable light source. This device may be used in extreme conditions either on land or at sea. It is designed to provide sufficient lighting during times of extreme conditions. The device is designed to be portable.

(9) The device 5 will be comprised of a base member 10 on top of which is mounted an inflatable light structure 11, which will be translucent to provide the necessary amount of lighting for any given condition. The light structure 11 will be a predetermined height or length and likely cylindrical; it is anticipated that different lengths may be used.

(10) The light structure 11 is likely to be of a synthetic material, although a variety of other materials may be used. One of the challenges with this type of device is controlling and venting the immense amount of heat that is generated. This is done using several different features that are unique to this light fixture but work in conjunction with each other to achieve the purpose of heat control. The features include the following: ventilation holes, heat sinks, a set of blowers and the ability to regulate the current.

(11) It is important to regulate the amount of heat to enable the device to be used for longer periods of time and also extend the life of the equipment.

(12) The light structure 11 will house a LED array on the top of the tube such as depicted in FIG. 4 and will be secured to the interior of the tube using a plate 20. Ventilation holes 35 are placed on the plate 20 to allow some of the heat to be dissipated during normal operation of the device. FIG. 2 depicts a top view of the plate 20 with the ventilation holes 35.

(13) The LED array 25 is comprised of a series of individual panels with the front of the panel depicted in FIG. 5 and the back view of the individual panel depicted in FIG. 6. The individual panels are arranged in a hexagon shape such as depicted in FIG. 3. A cage that appears in FIG. 3 is not claimed as part of this invention but is used to protect the LED light 15.

(14) A plurality of heat sinks 50 are placed on the interior of each of the panels of the LED array to dissipate heat as well. A heat sink 50 is placed on each of the individual LED panels. The choice of material for the heat sink is balanced between the need to maintain inflation of the tube while providing some means to dissipate heat.

(15) The set of blowers 55 that are used to inflate the tube will force air past the heat sinks 50 and through the ventilation holes 35 to control the heat buildup in the unit. The set of constant speed motors 60 control the operation of the set of blowers. A power source, either an electrical cord or a generator, will provide power for the components of the device.

(16) A metal halide light uses ballast to regulate current within the light. The metal halide light is either completely off or completely on. If a metal halide light is turned off, there must be a cooling down period, which is referred as the “strike time” of the light in the industry, before it can be turned back on safely. This delay may become problematic in the field using a metal halide light.

(17) Conversely, a LED light driver converts the alternating current from either the electrical cord or the generator to a direct current; the conversion is accomplished by a LED driver that will drive power to the individual LEDs in the array. One of the advantages of the LED array is energy efficiency because the individual LEDs do not require much power (usually between 2V and 4V) to be operational. However, a LED, to function at its maximum potential, must operate at a constant, exact voltage; this is accomplished by the LED driver. There are different types of LEDs on the market but the LED driver that is used in this application is a mix mode LED driver with a power factor correction. This type of LED driver will provide both constant voltage and constant current to protect the light and maximize the life of the light.

(18) With this application the user can moderate the LED array by supplying power to all the individual LEDs 30 on the array (light at 100% power) or turning off one-half the individual LEDs on the array (light at 50% power). If only one-half the individual LEDs are used it will result in less power consumption and less heat generation. The ease of power regulation with an LED array does not sacrifice illumination; the device will provide illumination at either “full power” or “half power” and this can be achieved by simply throwing a switch and does not require the cool down period of the metal halide light.

(19) A control box 45 that includes the LED drivers 65 permits the ease of power regulation within the LED array. When the entire LED array is to be illuminated a switch for full power on the illumination switch 67 is set to the 100% setting; when only one-half the LED array is to be used a switch for the illumination switch 67 is engaged to the 50% setting. A power switch 66 will allow the LED array and all other components to become operational. A separate switch for the lamp 68 is included. A blower switch 69 is also included to enable the user to operate the set of blowers 55 independently of the other components, if desired; the blower switch 69 controls the operation of the set of constant speed motors that operate the set of blowers 55.

(20) With the traditional metal halide light the previously mentioned methods of current regulation and heat dissipation were not available. While the blower was used to inflate the tube, there were no ventilation holes and no heat sinks in the metal halide light. Additionally, there was no way to regulate the current in the metal halide light example.

(21) Another disadvantage of the metal halide light was the long strike times that were involved between turning the light off and on. If the light is on and then turned off, the user must wait for the light to cool down before it is turned back on. In the example of an LED array the light can be turned on without needing a cool down period.

(22) In order to stabilize the lighting structure, particularly during windy conditions, a pole attachment flap 22 will be positioned on the side of the light structure 11. This pole attachment strap 22 will be secured to a stabilizing poles 21, which can be inserted into a cavity on the top surface of the base 10 to secure the stabilizing poles to the pole attachment strap 22.

(23) In the event of a sudden power failure the stabilizing poles 21 will prevent the tube 11 from suddenly deflating and injuring persons on the ground and preventing damage to the LED light.

(24) The electrical circuitry that operates the blower and the light will be constructed so that these elements will operate separately from each other; the wiring is constructed so that the light will not operate until the blower is operational to prevent a build up of heat by the light. The circuitry is configured so that the lamp can be turned off independent of the blower. Prior to the device being deflated through the use of a plurality of air vents, the lamp can be turned off to allow the structure to cool down before it is deflated and stowed again on the base.

(25) While the embodiments of the invention have been disclosed, certain modifications may be made by those skilled in the art to modify the invention without departing from the spirit of the invention.
