Field of the Invention

The present invention relates to a surface mounted pool lighting fixture, having the feature of long-term use, for which the failure risks were reduced to minimum levels, and having a high level of safety measures.

Prior Art

The pool fixtures employed today are generally have coarse and wide-width designs. Since the surface mounted pool fixtures have a broad structure at the edge of the pool, the persons in the pool tread on them when going out of the pool, thus causing them to give a good many failures.

The surface mounted pool fixtures of the prior art employ halogen or LEO fixtures. Since the life of the halogen fixtures is short, longer lasting LED fixtures started to be preferred recently. Although the LED fixtures do not easily fail, heat problems occur, and cooling the pool fixtures cannot be carried out in the prior art.

Another technical problem experienced with the pool fixtures is the leakages of the electricity coming as low voltage as a result of water leakage from the water-energy connections of the product, thus failures caused by these electrical leakages. The energy inputs of the surface mounted pool fixtures is provided by fittings in the prior art. The fittings leak water easily. To prevent water leakages, epoxy is used in some fixtures, but the water leaked from the cable joint and jointing places, passes through the cable wires, and flows into the fixture from where there is an energy transition. For this reason, sufficient sealing cannot be provided Failure to provide sealing cause the fixtures to break down and discarded, or be returned.

As for the LED fixtures, the largest problem is the heating problem. Since the pool fixtures have a coarse and wide-width design, the surface area becomes narrow. Since channels and aluminium, which would enlarge the surface area are not employed in the fixtures, cooling cannot be provided and the wide-width structure of the pool fixtures causes the products to break down because of the heat. In the patent application with number TR2Q06/00591 ; our invention relates to the fixtures known as pool fixtures in the lighting industry, wherein the LED diodes giving various colours are used for lighting instead of tungsten or halogen lamps, and thus being able to illuminate a pool in requested colors, and being able to obtain other requested colors by changing color settings of the LEDs. The system consists of an outer body, an inner body, a body with bent glass, and LEDs.

As a result, because of above-mentioned negativities, a need to make an innovation in the art arose.

Detailed Description of the invention

The present invention is a pool lighting fixture (10) comprising the cooling fins (63) having an integrated structure with the cooling surface (62), which is structured below the top cover (20) and the top glass (21), and makes sure cooling of the absorbing surface (62), and a LED piate (40), which provides lighting below said cooling fins (63) and the top glass (21). It comprises the silicone gaskets (30), which provides sealing of the lighting fixture (10), and the energy input part (50), which provides said lighting fixture (10) with energy input. It comprises the junction box (64), in which the energy input part (50) is seated, and the epoxy receptacle (65), which occupies the place where the cable coming from inside the fitting to said junction box, thus help making sure sealing. In order to fix the angled screws to the energy input part (50), the angled slots (53) were formed. A simple and practical screwing is provided by means of the angled slots (53).

It includes a cable entry (66), through which the cables going into said junction box (64) pass. And comprises the energy receptacle (61), housing the energy circuit of said lighting fixture (10), and the main body (60), which accommodates all these elements on it. The main body (60) produced from aluminium material is coated by GEOMET 321 B, the coating material with trademark of American Dakro in order to protect its exterior surface from corrosion. This coating, by itself, gives an advanced protection to the aluminium body against water. In addition, Electrostatic Powdered Painting is applied over this coating in order to protect the In the exploded view of Figure 1; the lighting fixture (10), as put in the middle to provide lighting in the pools, comprises, by its components, the top cover (20), the top glass (21), the silicone gasket (30), the LED plate (40), the energy input part (50), and the main body (60).

In order to be able to apply lighting without liquid leakage in the pools, especialiy on the lighting fixture (10), firstly the top cover (20) and the top glass (21), are mounted to each other by the screws, which passes into the screw holes on the top cover (20) and the top glass (21). And the LED plate (40) housing the lighting sources is applied to the lower side of the top glass (21). Around the LED plate (40) is compressed by the silicone gasket (30), thus liquid contact with the main body (60) is prevented. The silicone gasket (30) and the other parts on the upper side are seated into the silicone gasket recess (67), which is designed as suitable to the form of the silicone gasket on the body with aluminium cooler (60). There are the top glass screw holes (70), which make sure mounting of the top glass to the lower body in the middle of the silicone gasket recess.

As can be seen in figure 2, there are the top cover screw holes (69) on the exterior of the silicone gasket recess (67), and mounting holes (68) for mounting the lighting fixture (10) to a wall or different grounds. As for the midsection of the silicone gasket recess, there is the energy receptacle (61) housing the energy circuit in the part nearest the outside. On the upper section of the energy receptacle (61), there is the cooling surface (62), which covers the receptacle, in which the energy circuit is found, and absorbs the high heath produced on said LED plate (40), and provides this LED plate (40) with cooling from a wide surface. And at the exact center of the main body (60), there is the junction box (64). which is the receptacle, in which the energy input part (50) is positioned. The junction box (64) is designed in a round form, and there are cylinder-like projections on its four corners. In this way, the energy input part (50) having a round form whose 4 corners are designed with projections can easly sit in this section. The connection elements (51) on the energy input part (50), and the connection slots (52) housing these elements are attached by the silicone gaskets (30) to the hexagonal receptacles in the middle of the energy input part (50) (see figure 7), thus making sure the energy is transferred from the cable in the junction box (64) to the inside of the fixture (10). There are the screw silicone gaskets (30) around this section, which prevent liquid leakage. And the outer side of the energy input part (50) is designed with the screws, which connects the energy input part to the main body (60), and the silicone gaskets (30), which covers the outer side of these screws, thus providing sealing. Again, in figure 2, in the bottom view of the main body (60) of the lighting fixture (10) subject matter of the invention; there are the cooling fins (64), which are positioned around the junction box (64) designed in cylindrical and projecting form at the midsection, by centering the junction box (64), Since the surface area on the aluminium body (60) is increased thanks to the cooling fins (63), the water in the pool contacts more with the aluminium body (60), and a better cooling is provided, thus solving the heating problem of the junction box (64).

As for figure 4, the representative view shows the main body (60) and the main body (60) cooling surface (62), and LED plate (40) contact surfaces (41). Said main body (60) cooling surface (62) is contacted with the contact surface (41) from all the surface indicated with the arrows. As a result of contacting the contact surface (41) with a cooling surface (62) from a surface with a wide area indicated with arrows, heating and the technical problems arising from heating are resolved. In this way, a lighting fixture (10) having a long service fife is obtained.

As can be seen at the lower part of the junction box (64), an epoxy receptacle (65) was formed. The epoxy receptacle (65) provide sealing by filling in the place where the cable coming from inside the fitting is found. In this way, water ingress to the junction box (64) is prevented, thus avoiding failure of the electronic components as a result of water contact. After pouring in the packing material of fluid state in the epoxy receptacle (65), the packing material concretes in the epoxy receptacle (65). Thus, water leakage into the junction box (64) and water access to the special cables are highly prevented.

And on the side of the junction box (64), the cable entry (66), designed in a form having a rounded lower side, and in the shape of a rectangular prism is found, and the cable entry (66) to the junction box is made from this section.

The lighting fixture (10), the function of which are described in detail above is composed of 6 parts, which can be mounted on one another, 2 sealing gaskets, and 22 stainless connecting screws.

When installing the fixture (10), screws are attached together with the O-ring silicone gaskets (30) providing sealing, which are connected to the energy input part (50), and clamped from behind with the nuts. Then, the terminals are seated on the nuts, and the cables in the circuit element are seated onto these terminals. This allows conductivity. While 2 cable entries (66) is sufficient for the energy input part (50) when the light is monocromatic, it is required to open the other two cable entries, which are closed, and use 4 cable entries (66) in the cases when it is multi (RGB) colored. The 4 screwing holes in the energy input part (50), and the energy input apparatus are installed in the aluminium body (60) Then, the circuit element is installed in the energy receptacle (61) hole.

The LEO plate (40) is installed in the aluminium body (60) with 3 screws. Then, the silicone gasket (30) is attached, and seated onto the top glass (21), and together with the 8 screws and nuts, the top glass (21) is clamped to the main body (60). Since the silicone gasket (30) is also jammed in between, sealing is provided. Conduction is provided by the cable, which is passed through the junction box (64) cable entry (66) of the aluminium cooler body (60). and by pouring in epoxy also from the epoxy receptacle (65) after passing tne cable, another structure is formed, which prevents water leakage.

Thereafter, the aluminium body (60) is installed in the wall from the mounting holes (68). Finally, the top cover is passed through the top cover screwing holes (69), and gets ready for usage.
