Description

LED LIGHTING FIXTURE WHICH HAS ITS MAIN BODY MADE OF PLASTIC MATERIAL Technical Field

The invention relates to a LED lighting fixture which has a cooler chassis mounted and / or bond on its main body, which comprises LED and / or similar LED clusters mounted, which comprises an optical structure (lens), which has connection omponents that connects a LED driver and LED and/or similar LED clusters, which has a pole connection apparatus that enables connection of said fixture to poles, which has its heat conduction enhanced and can easily be mounted or dismounted, which has a lateral surface that LED and/or similar LED clusters can be mounted as a warning light and which has its main body made of plastic material.

More specifically the invention relates to a LED lighting fixture, which LED and/or similar LED clusters are used, that has a plastic body instead of an aluminum body that provide the cooling process, which provides cooling with a chasis mounted on its main body, which comprises LED and / or similar LED clusters mounted, which comprises an optical structure (lens), which has connection omponents that connects a LED driver and LED and/or similar LED clusters, which has a pole connection apparatus that enables connection of said fixture to poles, which has its heat conduction enhanced and can easily be mounted or dismounted, which has a lateral surface that LED and/or similar LED clusters can be mounted as a warning light and which has a plastic body.

Background Of The Invention

In LED and / or similar LED clusters there is an inversely proportional relationship between light build-up and junction temperature. The increased temperature in the LED and / or similar LED clusters reduces the light flow due to the color of the LEDs and / or similar LED clusters. The fall of the light flux causes the LUMEN level of the power pressure to drop in the LED and / or similar LED clusters and the desired light can not be obtained when high electrical energy is consumed. That is why the heat generated on the LED and / or similar LED clusters is reduced by cooling processes.

LEDs and / or similar LED clusters can not convert all of the electrical energy they use into light energy.

This electric energy, which is spent on LEDs and / or similar LED clusters and does not convert to light energy, is turned to heat. In this case, the LEDs and / or similar LED clusters heats up. This high temperature causes the semiconductor structure of LED and / or similar LED clusters to be destroyed and damaged.

For this reason, it is necessary to remove the generated heat from the LED and / or similar LED clusters with cooler assemblies.

For this purpose, in the existing lighting fixtures, the body production is realized by using aluminum alloys and the cooling process is revealed by the bodies manufactured from aluminum alloys.

In the process of manufacturing the bodies of lighting fixtures using aluminum alloys, various methods are used in consideration of such factors as mold investment cost, product quality, product cost, working time, used quantities.

Aluminum High Pressure - Aluminum Injection Molding Method,

Aluminum high pressure - Aluminum Injection molding method is based on filling molten aluminum raw material with a die made of metal under very high pressure. Thanks to the high pressure applied, it is ensured that the mold is filled very quickly in high quantity.

High pressure is applied until the solidification is completed and then the mold is opened and the part is removed from the mold with the help of pushing rods and the process is completed.

Advantages of Aluminum Casting Method:

It is suitable for casting small pieces of complex shapes. Thin-walled parts ensure full filling of the mold. The production speed is high and the mechanical properties of the fine-grained internal structure, which is formed as a result of rapid cooling, are good.

Disadvantages of Aluminum Casting Method:

Only small / medium sized parts can be produced, the design of the molds is difficult and expensive, a high pre-investment is required for the casting machine. Because of the cost of mold to be used in casting, it is only economical for mass production and for many parts, and it is not possible to cast melted materials at very high temperature by this casting method.

Aluminum Extrusion:

Aluminum extrusion is the definition of shaping the material by forcing the aluminum to flow through a hole formed in a mold. After extrusion, the mold is applied along the aluminum profile.

Anodized Aluminum: We can refer to an application in which anodization is integrated with aluminum. The reason is aluminum resistance is not very good in corrosive environments. At the same time, it can not show much resistance to temperature. Therefore, anodizing is performed. We can say anodizing, alumina special coating or electrolysis.

Anodising is a process that is defined as electrolysis. That is, the process of coating aluminum with an electric current and coating with an oxide layer. After forming this layer, a porous state is formed and then the pores are closed after applying dye. A special, strong and good-looking coating is obtained. Optionally a coating thickness of 10 to 20 microns can be made.

Press forming of aluminum sheet:

The method based on formation of aluminum sheets by means of hydraulic or eccentric presses with plaster molds consisting of male and female is based on the formation of the desired body by connecting the parts forming the different layers with rivets or screws. The biggest disadvantage is that the forms that can be created are limited.

Alumina clay plaster:

Aluminum plate is covered with a loom on a metal mold. It is preferred if the amount of products to be manufactured is small. Aluminum cobbles have high dimensional tolerances in the spinning process. Thus, in addition to being not preferred in precision work, forms that can be formed can not be made out of cylindrical shapes, so that any desired pattern can not be made as desired. But besides this, the cost is very cheap.

Sand mold aluminum casting:

Sand mold casting method is one of the most used casting methods. It is preferred because of its low mold cost and its application in many different sized parts. Gravity is utilized during casting and this method is suitable for single or small scale batch production of cast parts.

The advantages of the sand mold are its ability to be used repeatedly with the great flexibility of water and other replenishment, and the cheapest molding method. The disadvantages of the sand mold are that it is not preferred in situations where higher dimensional accuracy and high surface quality are desired in situations where the mold must have higher strength and erosion resistance.

The various methods used in the above process of manufacturing the bodies of lighting fixtures using aluminum alloys are briefly described. In the manufacturing phase, the manufacturer chooses one of these methods by considering the factors such as the amount of the product to be manufactured, mold investment cost, product quality, product cost, working time, etc. when selecting these methods.

More important than these options is the design of the main body which is formed as a coolant so that cooling can be carried out.

Depending on the type of LED and / or similar LED clusters to be used in the lighting fixtures, the thermal resistance of the LEDs and / or similar LED clusters depends on the current and the value of the applied current, and the amount of heat generated on the surface of the LED and / or similar LED clusters the thermal resistance between the sheath, the thermal resistance of the coolant, the thermal resistance between the LED and / or similar LED cluster sheath and the coolant, the amount of heat in the outdoor environment, and so on.

When the design is made, the mass of the lighting main body, the sizes and visual forms of the cooling fins are determined.

Considering the design of the specified lighting main body, one of the molding methods is preferred according to the other factors such as mold investment cost, product quality, product cost, working time, used quantities.

After the mold production, the main body is produced according to the selected manufacturing method.

Since the various burrs are formed on the product when sand mold casting, aluminum plastering, aluminum injection casting methods are used, these burrs should be cleaned by machine and / or hand after the main body print. The aluminum product should be sandblasted for surface cleaning and compression of the molecules on the outer surface and should be free from contamination such as grease on the products as a result of printing.

The main body of the lighting must be threaded with holes and holders and holes for the holes to be used for fitting materials such as LED and / or similar LED clusters, LED driver, connectors, optical structure (lens).

Apart from the anodic methods, the main body should be subjected to dyeing to obtain the desired color.

During these processes, problems such as manufacturing time, labor costs, manufacturing and application difficulties, metal processing machine requirements, dyeing system requirement, high mold cost in high volume production occur.

These drawbacks and disadvantages, high cost, production difficulties, and the development of alternative methods and systems are mandatory. In this point of application, the system and the main body made of plastic material with the lighting fixture has been put out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The invention relates to a LED lighting fixture (10) which has its LED and/or similar LED clusters (40) cooled by a cooler (30) placed and/or mounted on the plastic body (20), instead of an aluminum and/or similar metal made main body. Said LED lighting fixture (10) has LED and/or similar LED clusters (40) and an optic lens (60) mounted on its cooler (30) and has LED driver (50), connection apparatus for connection of LED driver (50) and LED and/or similar LED clusters (40) inside its plastic body (20). In addition, LED lighting fixture (10) has a pole connection apparatus (1 10) which enables the mounting to poles. The plastic body (20) can be opened/closed via a hinge (70) that is placed between lower and upper cover (20.1 ). A lateral LED junction body (90) enables the plastic body's (20) lateral surface to be placed with lateral LEDs and tempered and / or plexi glass, which support as visual appearance to the plastic body (20) or which can be used as a warning light in misty environments with an electronic circuit that enables twnikling effect of the said light. The LED lighting fixture (10) is waterproof and its heat conduction enhanced and also has the feature to be mounted/dismounted easily.

The LED lighting fixture (10) plastic body's (20) lower and upper covers (20.1 ) are designed to be the same in the design phase. In this respect, mold design for the LED lighting fixture (10) the plastic body's (20) lower and upper covers (20.1 ) are not separately designed and major advantages like shortening of the manufacturing time, reducing labor costs, mold cost etc. have been achieved.

In the manufacturing phase, LED and / or similar LED clusters (40) and optical lens (60) are first connected to the cooler (30) by known mounting methods. After the LED lighting fixture (10) plastic body's (20) upper and lower covers (20.1 ) are manufactured in the plastic injection molding machine (20), pins (80) are placed between the lower and upper cover (20.1 ) and the cooler (30) the pre-mounted with the LEDs and / or similar LED clusters (40) and the optical structure (lens) (60) is positioned afterwards on it.

What is important here is that lower and upper cover openings (20.2) are formed on the bottom and top covers (20.1 ) and the cooler (30) is centered on said opening.

By positioning the cooler (30) in the center of the lower and upper cover openings (20.2), air flow is provided through the cooler (30).

The pins (80) for fixing the cooler (30) on the LED lighting fixture (10) are applied at least 2 and / or more.

In this stage, the electrical connections of the LED and / or similar LED clusters (40) pre- mounted on the cooler (30) and the LED driver (50) placed in the plastic body (20) are realized using the cable connectors. At the same time, the light fixture (1 10) is connected between the lower and upper covers (20.1 ) which form the plastic body(20) of the LED lighting fixture, and when the lower and upper covers (20.1 ) are closed to each other, it is fixed by mounting nut and / or screws.

Air gaps that provide cooling are formed between the lower and upper surfaces of the cooler (30) located at the center of the lower and upper cover openings (20.2) on the lower and upper cover (20.1 ) whcih enables air circulation regardless of coming air and/or wind direction from upside or downside.

In this way cooling is provided in the LED lighting fixtures (10) where the LEDs and / or similar LED clusters (40) are used.

In the present system, it is possible to eliminate the heat that causes big problems and costs, and at the same time, it is possible to manufacture the LED lighting fixture (10) from the plastic raw material, thus providing cost advantages and extending the lifetime of the LED and / or similar LED clusters (40) and LED lighting fixtures (10).

Instead of high weighing existing systems made of aluminum material, large body weights are minimized with the help of used plastic raw material. In this way, the difficulties encountered during the transportation and mounting of the LED lighting fixtures (10) are eliminated.

If desired, the LED clusters placed on and / or mounted on the lateral LED junction body (90), which can be mounted between the lower and upper covers (20.1 ), provides a visual / decorative additive according to the preferred color. Mechanical resistance is provided by the addition of tempered and / or plexy glass (100) on the lateral LED connection body containing the LED assembly.

Lateral LED can be made available as a warning lamp in foggy and hazy environments by using amber color on the cluster and, if desired, blinking it with an electronic circuit.

Since the lower and upper cover (20.1 ) are made of plastic raw material, it can be produced according to the desired color when printing with plastic injection machine, whichever color is desired, and negativities in the production process of aluminum raw materials are eliminated and one of the manufacturing steps is removed.

At the same time, manufacturing errors like burrs, scratches, etc., due to the use of aluminum in the existing systems have been eliminated and the requirement and time spent on correction of these errors with processes like welding, sanding, degreasing and so on have been removed.

In addition, requirements like holes, holding apparatus and threading with guides that are needed for holding parts like LEDs and / or similar LED clusters (40), LED driver (50), optical structure (lens) (60) have all been removed.

With the invention, an LED lighting fixture (10) made of plastic raw material has been developed, reducing the time of application, minimizing labor costs, minimizing raw material costs and facilitating application.
