FIELD OF THE INVENTION:
The present invention relates to a simpler heat exchange assembly which is herein used for LED lighting system which involves the use of heat pipes attached to a specially engineered multi-purpose base plate with minimal essential components to dissipate the heat.

BACKGROUND OF THE INVENTION:
LED (light emitting diode) is a two-lead semiconductor light source. It is a p-n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. Along with the production of light, these diodes produce heat when they are switched on by applying current. Upon application of direct current, LED’s emit light along with radiant energy. The LED chips used for producing LED light are mounted on a holding surface. The light emitted from the surface of the chip which faces the mounted surface, is converted into heat while the opposite surface of the chip emits the light. The heat generated on the surface of the chip facing the mounted surface increases with the increase in the power of the LED light. This heat causes damage to the chip, thereby reducing the age of the LED light. So proper heat dissipation systems are required to dissipate the heat produced from the LED chips.

DETAILED DESCRIPTION:
The nature of the invention and the manner in which it is performed is clearly described in the specification. The invention has various components and they are clearly described in the following pages of the complete specification.
Heat dissipation is a type of heat transfer. During heat dissipation heat from a hotter object is transferred to colder objects and the surrounding environment. A number of heat management techniques have been developed for managing heat released from LED systems. In some systems, heat is conducted to a heat sink from the LED junction and then dissipated to the ambient by natural convection or radiation while in other cases the LED systems are cooled by using extended surfaces like plate fins and pin fins which significantly increase the heat transfer area over unfinned heat sinks.
The present invention is a simple heat exchange assembly for LED lighting system using heat pipes with minimal components which comprises a specially engineered multi-purpose base plate. This base plate has receptacles for holding the LED PCB board on its front side along with receptacle for holding the LED lens. This cluster of lenses gives proper beam angle to the LED light. This way the base plate itself works as a reflector of light. It also works as a primary heat sink which is directly connected with the LED PCB for immediate dissipation of heat. On the rear side of the base plate are present hollow plugs which are then transformed to heat tubes by simply mounting extruded finned hollow tubes. These tubes are further treated for evacuation and then insertion of evaporative fluids and its vapors. The size and number of heat tubes added to a LED lighting system can be changed depending on the wattage of the system. This multi-purpose base plate works as the central most critical component which works as a chassis for the entire LED lighting system, on which all the components are mounted or supported for their efficient and easy functionality.
Heat tubes used in LED lighting system are usually made of copper and or aluminum, which after treatment for evacuation and insertion of fluids and its vapors, are connected to the source of heat which are the LED light PCB. One end of these heat tubes is in touch with the heat source where the LED PCB is mounted. On switching on the LED light, heat is emitted from the PCB and transferred through the vapors present in the heat tubes, to its farthest end. The vapor phase is a mixture of water and some organic solvents like alcohol. This mixture is a better conductor of heat than metals including copper. The heat from the heat tubes is transferred to the finned heat exchanger thereby reducing the heat present near the LED light PCB in the fastest possible time, thereby keeping the chips cool. This fast transfer of heat from the LED light PCB, contributes to the longevity of the LED chips as well as reduces the rate of lumen intensity fall from the LED chips.
Displayed in Fig. 1 is the diagram of the complete LED light system of the present invention wherein are displayed a two dimensional view, a three dimensional view as well as a cross section view of an LED light system having a single thick heat tube. Fig. 2 gives the diagram of a complete LED light system which has multiple heat tubes for dissipation of heat. As shown in the figure, the LED light is hung from a suspension hook which is supported on a driver suspension box. Ideally, this suspension box has a height of 69 mm and a diameter of 208 mm. However the dimensions may vary according to the requirement. This box holds the converter which converts the alternate current to direct current which is the basic requirement of LED chips. The farthest end of the heat tubes (pipes) are attached to the driver suspension box while its front end goes into the base plate. The ideal heat of these heat tubes is 230 mm. The base plate acts as a heat plate cum reflector which ideally is 100 mm in height and 355 mm in diameter at its open end. Although the ideal dimensions and shape of all the parts have been mentioned in the diagram, these dimensions and shape may be changed according to the requirement.
Fig. 3 gives the exploded 3D diagram of the parts of a LED light system wherein all the parts of the light system have been separately shown in their correct order. The topmost is the suspension hook followed by the driver suspension box. This is followed by a thick heat tube with a number of extruded fins. Below the heat tube is the specially designed base plate which also acts as a reflector, having a single receptacle for a single heat tube. This base plate also has receptacles for holding the LED PCB board on its front side along with receptacle for holding the LED lens. Similar to Fig. 3, Fig. 4 gives the exploded 3D diagram of the parts of a LED light system wherein all the parts of the light system have been shown separately in their correct order in which instead of a single heat tube, as shown in Fig. 3, multiple heat tubes and their receptacles have been displayed. The rest of the diagram is same as shown in Fig. 3.
Fig. 5 gives the diagram of an extruded finned heat pipe (tube) used in the LED light system of the present invention which includes a section view of the finned heat pipe. The diagram shows the finned heat pipe design, the hollow of which is filled with an evaporative fluid and closed with a hermatic plug. The evaporative fluid is a mixture of water and some organic solvents like alcohol which makes it a better conductor of heat as compared to metals like aluminum and copper. Moreover the fins in the heat tubes provide more area for the heat to spread out thus dissipating the heat at a faster rate leading to increased longevity of the LED chips.
Fig. 6 gives the diagram of the different views of the base plate of the LED light having multiple heat tube receptacles wherein the rear view shows the heat tube receptacles as well as receptacles for holding the LED PCB board. The front, rear, side and 3D views of the front and rear of the base plate cum reflector has been shown in the diagram. Also shown is the half sliced view of the base plate, for its complete understanding. Fig. 7 also gives the diagram of the different views of the base plate of the LED light system having multiple heat tube receptacles which includes cross-section view, side view, 3D view as well as a partially cut view of the reflector cum LED PCB receptacle, for its complete understanding.
Fig. 8 gives the diagram of the different views of the base plate of the LED light having single heat tube receptacle wherein the rear view shows the heat tube receptacle as well as receptacles for holding the LED PCB board. The front, rear, side and 3D views of the front and rear of the base plate cum reflector has been shown in the diagram. Also shown is the half sliced view of the base plate, for its complete understanding. Fig. 9 also gives the diagram of the different views of the base plate of the LED light system having single heat tube receptacle which includes cross-section view, side view, 3D view as well as a partially cut view of the reflector cum LED PCB receptacle, for its complete understanding.
Although all the above mentioned diagrams show a circular base plate of the LED light system along with cylindrical heat tubes, the complete LED light system can be made of different shapes having square, triangular, oval etc base plates and their corresponding heat tubes.

The simple heat exchange assembly for LED lighting system using heat pipes with minimal components is highly advantageous. It eliminates the need of a separate LED PCB board which is common in the currently available LED lights, as the LED PCB receptacles are present on the specially engineered multi-purpose base plate such that the PCB’s are attached directly on it. So the extra expense of a PCB plate is cut down. The heat tubes in the LED light system of the present invention start directly from the base plate due to the presence of their receptacles due to which one step in heat transfer is eliminated and heat transfer from the LED PCB becomes faster. The heat emitted from the PCB’s is immediately and directly transferred to the heat tubes having extruded fins which completely dissipate the heat of the system. As the heat transfer is immediate, the longevity of these LED PCBs increases thereby making it advantageous. It also reduces the rate of lumen intensity fall from the LED chips. Thus the specially engineered base plate is an economical multipurpose component which has;
• Receptacles for holding the LED PCB board;
• Lens cluster which gives the LED light a proper beam angle;
• Additional reflector for stray light beams;
• Primary heat sink which directly connects with the PCB or LED chips for quick heat dissipation;
• Provision of attaching heat tubes at the rear of the base plate for immediate and enhanced heat dissipation; and
• Flexibility to change the size and numbers of heat tubes for making the LED lighting system of variable wattages.
