Abstract
Description
- The engineering solution relates to means for illuminating a territory, mainly under emergency conditions. It is intended for use, when electric power is off due to emergency or disaster, and also during construction works, repair works or search-and-rescue operations in the night time.
- Some inflatable lighting installations are known from patent publications (
US 6322230 B1, published on 27.11.2001 ;RU 2192581 C1, published on 26.02.2001 RU 2286510 C9, published on 10.04.2006 WO 02/063207 A1, published on 15.08.2002 - A drawback of the known lighting installations is that they are not configured for using LED (light emitting diode) light sources for illuminating, which would provide an illumination level comparable with conventional gas-discharge lamps, in particular, with sodium-vapor lamps commonly used in such installations.
- A known emergency lighting installation (
RU 139894 U1, published on 27.04.2014 - This installation does not contribute to solving the problem of illuminating a territory with LED light sources, as emergency installations like this do not have means for guaranteed cooling powerful LED light sources. The LED-based strob lamp is intended for signaling only and it cannot be used for providing illumination.
- Meanwhile, LED light sources have a number of substantial advantages in comparison to other known light sources, namely, they have longer life time and lower power consumption; they are steadily operable in a wide temperature range; they start immediately after powering on and provide a high contrast, which promotes better clearness of the illuminated objects.
- However, a heatsink is required to ensure reliable operation of LEDs. In particular, there is a known lighting device (
RU 77024 U1, published on 10.10.2008 - Using devices similar to the above-indicated one in inflatable lighting installations does not comply with relevant requirements regarding illumination, as these installations are mainly used for illumination of large areas during works related to a high level of danger like accident elimination, disaster elimination, etc., when a substantially higher illumination level is required.
- Increase in number and power of LED light sources inevitably causes the need of increasing heat-removing surface of a heatsink and, consequently, to raising its size and weight. There is a known extra-high-power LED floodlight (
RU 144224 U1, published on 10.08.2014 - Using a massive heatsink in inflatable lighting installations deteriorates their operational performance, as lifting a light source equipped with such a heatsink by means of an air flow forced into an inflatable shell may be difficult, even impossible in some cases, due to large weight of the heatsink and necessity of maintaining greater pressure inside the shell. Moreover, the heatsink combined with the light source may fall down upon deflation of the shell, and it may cause personal injury of staff and damage of the installation.
- The claimed invention is directed at providing an inflatable lighting installation equipped with a LED light source ensuring a high illumination level, with no sufficient increasing weight of the installation upper part in an operational position thereof.
- A technical result attained by a lighting installation described herein is enhanced reliability and improved operational performance of the installation.
- The technical result is attained by a lighting installation comprising a base, an inflatable shell secured to the base, an air blower communicated to a chamber formed by the shell, and at least one electric light source placed inside the shell, wherein the lighting installation is equipped with a hollow unit secured inside the shell; the light source is installed on the hollow unit; a cave of the hollow unit is communicated with a cooling system for the light source; the light source is a LED light source; the cooling system is a liquid cooling system; and the cooling system comprises a pump communicated with the cave of the hollow unit by flexible pipes.
- In some embodiments of the lighting installation, its cooling system may be equipped with a heatsink and an expansion tank; the pipes may be spiral-shaped and may be secured to the shell; the heatsink may be placed on a longitudinal axis of the air blower. The cooling system may be positioned inside or outside the lighting installation.
-
Fig. 1 shows one example of implementation of the lighting installation according to the claimed engineering solution. - The lighting installation comprises a
base 1, aninflatable shell 2 filled with air and secured to thebase 1, anair blower 3 mounted in the base and communicated with atmosphere and with achamber 4 of the shell. At least oneelectric light source 5 is placed inside the shell 2 (four light sources are shown inFig. 1 ) and is connected to a power source by an electric cord (not shown). Thelight source 5 is fastened to theshell 2 via aflange 6 andfasteners 7. A powerful LED light source is used in the installation, which emits a considerable amount of heat. In order to remove the heat and to prevent overheating thelight source 5, the lighting installation is equipped with aheatsink 8 installed in thebase 1 and positioned on an axis of air flow moving from theair blower 3. Theheatsink 8 is filled with a liquid coolant. A hydraulic pump 9 and anexpansion tank 10 are sequentially communicated with theheatsink 8, and theexpansion tank 10 is communicated with adischarge pipe 11. In one embodiment of the installation, theheatsink 8, the hydraulic pump 9 and theexpansion tank 10 are installed inside the base 1 (seeFig. 1 ); in another embodiment, they may be installed outside thebase 1. - The
heatsink 8 is communicated with ahollow unit 12 configured to bear thelight source 5 and to provide cooling thelight source 5. Ahermetic cave 13 of thehollow unit 12 is filled with the liquid coolant and is communicated with theheatsink 8 by apressure pipe 14. If asingle light source 5 is used, it is mounted on the lower side of thehollow unit 12; ifseveral light sources 5 are used, they are mounted on different sides of thehollow unit 12. The lighting installation may comprise severalhollow units 12 positioned at the same height or positioned one above another or in any other combinations. Thepipes pipes - The above-indicated hydraulic components form a liquid cooling system for the
LED light source 5. Theheatsink 8, which is one of main components of the cooling system, hasheat exchanging ribs 15 on its outer surface, wherein the ribs are directed along an air flow forced from bottom to top by theair blower 3. This air flow passes throughpassages 16 between theribs 15. - Owing to a high heat capacity of the liquid coolant, the cooling system may be used without the
heatsink 8 under some conditions (favorable climate, low power of the light source, low liquid velocity in the cooling circuit). In this case, heat dissipation happens directly through the walls of thepipes - The
hollow unit 12 has input and output openings with corresponding sleeves communicated with thepipes hollow units 12 are used, they may be incorporated into a single circuit of a cooling system, either in parallel or in series; otherwise, each of thehollow units 12 may have an autonomous cooling system. - The installation is equipped with a
power unit 17. In different embodiments, thepower unit 17 may comprise an electric generator and an internal combustion engine, or an electric accumulator (not shown). The installation is also equipped with startup and adjustment equipment and with control means (not shown). - The installation operates as follows. Electric current is fed from the
power unit 17 to theair blower 3. Rotation of theair blower 3 causes atmospheric air to be forced into thechamber 4 of theshell 2, so the shell gets inflated and rises up along with thehollow unit 12, thelight source 5 and thepipes power unit 17 to theLED light source 5, which heats thehollow unit 12 during operation. Electric current is also fed to the hydraulic pump 9, which pumps the liquid coolant through the following root of the cooling system: the hydraulic pump 9 - the heatsink 8 - the pipe 14 - thecave 13 of the hollow unit 12 - the pipe 11 - the expansion tank 10 - the hydraulic pump 9. While the liquid coolant travels through the above-indicated root, it takes heat from thehollow unit 12, which is heated from thelight source 5, and loses heat in theheatsink 8. Thelight source 5 is cooled by the liquid coolant through a wall of thehollow unit 12. - Heated liquid coolant forced by the hydraulic pump 9 into the
heatsink 8 is cooled in theheatsink 8 so as the heat is drawn from the liquid coolant via theribs 15 of theheatsink 8, which are blown by theair blower 3 during its operation. After cooling in theheatsink 8, the liquid coolant is fed into thecave 13 of thehollow unit 12 and the above-indicated operational cycle is repeated. - Configuration of the lighting installation allows substantial increasing its power and luminous flux of the light sources owing to use of an effective liquid cooling system with a heatsink blown by a constantly working air blower of the installation. Use of LED light sources makes illumination of a territory more effective in comparison with known solutions of prior art. Reliability of the installation is also improved owing to increased thermal stability and enhanced endurance of the light source against mechanical impact. It should be noted that components of the cooling system may be positioned in the installation base or even apart from the installation, therefore weight of the upper part of the installation may be considerably reduced, and its size in operational position and power consumption may also be decreased.
