LEDs are light sources which generate light in proportion to the amount of direct current passing through them. Along with the production of light, these diodes produce heat when they are switched on. Here light is produced from one side of the LED chips while heat is generated from its opposite side. The heat generated from the LED light permanently damage the LED chips due to which they lose their luminous efficiency and start decaying which shortens the life of the LED light. Bay lights being expensive, cannot afford a short life span.

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.
LED lights are being used in all kinds of lighting systems throughout the world as they provide increased luminescence, are highly efficient, have increased life-span and are economical. They are semi-conductor devices which generate light through light emitting diodes, in proportion to the quantity of direct current passing through them. Along with the emission of light, these diodes also generate heat from the opposite side of light. Most of the LED lights are provided with heat dissipating systems which remove the heat from the system so that the LED chips are minimally damaged due to the heat generated. LED’s when exposed to heat, lose their luminescence, shortens their life and can become non-functional.
The present invention is a LED based bay light and assembling of LED based bay light which in spite of minimal components, accomplish highly efficient heat transfer using its specially designed reflector and other multi-functioning components. The assembling of this bay light is simple and easy involving minimal time.

As shown in Fig. 1, a stainless steel rope (2) hangs from the wire rope gland which is made of brass (1). Bolts (3) are provided to adjust the wire rope loop through the adjustable loop (4) made of stainless steel. The 3 core cable (5), cable gland nut (8), cable gland gasket (9) and the cable gland body made of brass (11), all of which are used for connecting the light to 220-240V A/C line for activation. The constant current driver cover (10) is made of aluminum and is supported on the light suspension hook (6) made of stainless steel with the help of a M-12 knurling nut (7) made of brass. With the driver cover is attached the polycarbonate plate (15) with the help of a M-12 knurling nut (14) made of brass and the hollow bolt for suspension hook (12) made of brass with a copper earthing spring (13) in between. The multipurpose polymer tray (17) is fitted over the polycarbonate plate with the help of the end cap dome nut (16) while the auxillary heat sink (20) made of aluminum, is fitted using the brass M-12 knurling nut (18) on the central shaft (21) made of brass and on the multipurpose tray at the sides with the M4 nut (19) made of stainless steel. The central shaft connects the auxillary heat sink to the primary heat sink cum reflector (22), made of aluminum, under which lies the LED chips covered PCB plate (23) which covered with a polycarbonate diffuse cover (25). This polycarbonate diffuse cover has fastening bolts (24) which pass through all the parts of the assembly to fasten them and fit the complete assembly perfectly such that all the parts are assembled as one without different fittings required to attach each part. This makes the assembling of the whole bay light fast and easy as all the parts assemble one over the other in series, through the fastening bolts.
Fig. 2 gives the cross section view of the bay light assembly of the present invention wherein the attached parts over the constant current driver cover (10) are the 3 core cable (5), the light suspension hook (6) and the cable gland nut (8). The earthing spring (13) is shown in the driver cover as the central shaft (21) passes through all the components of the bay light through their centre. The auxillary heat sink (20) lies just above the LED PCB plate (23) which is covered with the polycarbonate diffuser cover (25) with a little gap in between the plate and the cover. The primary heat sink cum reflector (22) holds the LED plate with the cover within it.
As seen in Figs. 1 and 2, the main components of this LED based bay light are reflector cum primary heat sink (22), LED filled printed circuit board (PCB) (23), multipurpose light cover with pre-mounted studs (25), a sleek auxillary heat sink (20), central shaft (21) with tightening mechanism, a multipurpose driver base plate (17), LED driver (15) and the LED driver cover cum light suspension mechanism (10). The unique features of this LED based bay light lie in its 3 specially designed components which make the assembly simple, quick to assemble, aesthetic and rugged. These 3 components are the specially designed LED light reflector cum heat sink, the multipurpose light cover and the LED driver base plate, all of which are discussed in detail below:
1. Specially designed LED light reflector cum heat sink: This component of the LED bay light is made of high purity highly conductive 2.5 mm thick aluminum. The thicker gauge of aluminum (2.5 mm) ensures much faster dissipation of heat (as compared to thin gauge aluminum) keeping the LED chips cooler. This reflector is burnished to make it highly reflective. As aluminum is one of the highly reflective metal, it has been chosen for making the reflector. Moreover, aluminum is also one of the best conductors of heat due to which the reflector also acts as a heat sink thereby serving dual purpose of increasing luminescence through reflection and dissipating heat through the heat sink.
This reflector cum heat sink also acts as a receptacle to hold the Printed Circuit Board (PCB) which is filled with LED chips. The heat generated from these LED chips, is immediately transferred from the back of the chips to the aluminum plated on the PCB and then to the aluminum heat sink cum reflector, thereby minimizing the damage caused by the heat to the LED chips. The aluminum surface of the heat sink exports the heat from all the sides, to the environment. The highly enhanced reflective area of the reflector works in tandem with the secondary heat sink provided on the top of the reflector, both of which transport the heat to the environment at the earliest, keeping the LED chips cool. The secondary (auxillary) heat sink has fins on its surface to provide enhanced surface area for heat dissipation. It is barely 5 mm away from the bottom of the LED chips and is connected through highly conductive aluminum to ensure short travel distance and time for the heat generated by the LED.
The pre-burnished and anodized reflector directs the light in a beam at an angle of 30 degree / 60 degree / 90 degree / 120 degree / 150 degree or any other desired angle as per the requirement.
2. Multipurpose light cover: This multipurpose light cover is specially designed with following functional and critical elements all of which are explained below:
(i) 5 precisely positioned insert molded bolts which act as fulcrum to assemble together all the components of the bay light. All the components of the bay light namely PCB, reflector, secondary heat sink, driver base plate and driver cover cum hanging assembly get arranged at their exact positions as the bolts pass through all of them. This makes the assembling of light very prompt and easy as all the above mentioned components just have to be mounted over each other in the pre-designed manner and finally tightened with the help of the dome nut. This unique feature increases productivity, decreases the cost as well as efforts to be applied by the worker to assemble the light.
(ii) Another unique feature of the light cover is that at the base of these bolts, monolithic plugs are created in such a calculated manner that when it is tightened, it presses the PCB to the reflector and the secondary heat sink, making the contacts strong, ensuring effective heat conduction.
(iii) Due to this specially designed plug, the need to screw tight the PCB against the heat sink has been eliminated. This saves significant cost, time, material and efforts.
(iv) In addition to pressing the PCB, these plugs also acts as strengthening anchor for the five bolts making the assembly rugged and functional for long.
(v) At the periphery of the light cover, there is a specially designed step of 1.5 mm depth. The LED filled PCB fits snugly in this slot. This peripheral step, along with the monolithic plugs of the 5 molded bolts of the light cover and the central shaft, ensure that the PCB is well pressed and is in tight contact with the heat sink from all sides for immediate dissipation of heat.
3. LED driver base plate: The LED driver base plate is made of special thermo plastic and has multiple functions. Its main function is to house the LED driver as well as protect it from heat originating from the heat sink below the plate. The special components of this base plate are:
(i) It has pre designed monolithic plugs fitted at the bottom which raises the height of the base plate upto 5 mm from the heat sink. The area in between the heat sink and the base plate acts as an insulator and rejects majority of heat from reaching the driver.
(ii) The white colour of the nylon used for making this base plate also reflects back the heat.
(iii) This driver base plate has pre designed heat plug holes which get screwed easily to hold the driver. Moreover it has a wall around it which does not allow water (rainfall) or any other material from outside to get into the driver component. This driver base plate also acts as a receptacle for driver cover which completes the assembly of the bay light.

The assembling of the LED based bay light is very simple, easy and effortless and can be done by any ordinary worker without technical knowledge. The steps of assembling the LED based bay light of the present invention are as follows:
Step 1: As shown in Fig. 3, the transparent light cover with insert molded bolts is taken. The detail of A shown in the Fig. 3, shows the step in the cover where the PCB is inserted. The LED PCB pressing plugs (26) are also displayed in the figure.
Step 2: As shown in Fig. 4, the polycarbonate plate fitted with LED chips (27) along with the central shaft and the cable from the light board, is mounted on the transparent light cover within the step and is pressed with the LED PCB pressing plugs.
Step 3: As shown in Fig. 5, the aluminum reflector cum heat sink is fitted on the assembly obtained in step 2, on the same 5 insert molded bolts.
Step 4: As shown in Fig. 6, the auxillary (secondary) heat sink, pre smeared with heat sink compound, is fitted on the assembly of step 3, on the same 5 bolts. Now fit the central shaft and move DC current cables through it. At this level, the assembly is tightened with primary nuts for additional security.
Step 5: As shown in Fig. 7, the driver base plate is fitted on the assembly of step 4 on the same 5 insert molded bolts. This figure shows the water protecting wall (28) of the driver base plate as well as the constant current driver mounting plugs (29) on this base plate along with the spacer plug (30) with holes, of this driver base plate.
Step 6: As shown in Fig. 8, the driver is fitted over the driver base plate and the electric connections are completed. The driver cover cum LED assembly is then mounted along with the suspension hook. Finally the dome nuts (displayed clearly in the Detail A in the figure) are tightened to complete the assembling of the bay light.
The LED based bay light of the present invention as well as its assembling method are quiet advantageous. This bay light has minimal components which are installed together to make the bay light due to which it is economical. The primary heat sink as well as the auxillary heat sink in the bay light work synergistically to immediately dissipate the heat generated from the LED chips, thereby keeping the LED chips cool and increasing their life span. The primary heat sink, being made of pure aluminum, also works as a highly efficient reflector, thereby increasing the luminescence of the bay light. This bay light involves the use of specially designed components which perform multiple functions. The primary heat sink also works as the LED reflector. The multipurpose light cover has 5 precisely positioned insert molded bolts which act as a fulcrum to assemble all the components of this light due to which most of the components of this bay light just need to be mounted one above the other in series on these bolts which need to be tightened only in the end with the dome nut thereby reducing the components, the time, the cost as well as the efforts involved. The multipurpose light cover has monolithic plugs at the base of the bolts which assist in making the contacts strong ensuring effective heat conduction. The light cover also has a step at its periphery for fitting the LED filled PCB snugly in the bay light. The LED driver base plate houses the LED driver and with the help of its monolithic plugs separates it from the heat sink which doesn’t allow the heat to reach the driver, thereby protecting it. This driver base plate also reflects back the heat and has screws to hold and fit the driver. Moreover the bay light assembly can be used for different light sizes as well as beam angles. The steps of assembling the LED based bay light are also very simple, easy and effortless and can be done by any ordinary worker without technical knowledge. Thus the bay light of the present invention is highly advantageous.
