    For this, there are lamps in the state of the art such as those shown in Figures 1 and 2, which correspond to those commercially called PAR 56, which are the most commonly used and which basically have the following elements:
    - A body or housing (1);
    - A heat sink (2);
    - A PCB board (3) (printed circuit board in its acronym in English) where the electronic components and LED lamps themselves formed by the chip and a primary optic are soldered;
    - A secondary optic formed by a lens (4) of a plastic nature, usually a polycarbonate, located on the PCB that serves as a cover to the assembly and is responsible for "shaping" the light according to the needs of the installation, is that is, divergent, convergent, etc., as defined the pattern of light distribution in one way or another;
    - A cover (5) for the lower closure of the housing (1) that has two electrical connections (6);
    - Different hardware (7) to connect the heat sink (2) with the PCB board (3) and this one with the housing (1), and
    - Finally, inside, a pair of cables (8.9) responsible for carrying the power supply from the electrical connections (6) of the cover (5) to the PCB (3).
    These lamps, once assembled, form a compact assembly as can be seen in Figure 2 which, in the case that they are intended to be installed in aquatic installations, that is, are submerged, logically have a tight seal.
    Figure 2 also shows the case of a recessed lamp, where the outer or visible part will be formed by the lens (4), while the part that will be housed in the niche of the wall or floor where it is installed It is formed by the outer part of the housing (1), forming between both, lens (4) and housing (1) a sealed cabin inside which the rest of the components are enclosed.
    Thus, in this type of lamps, commercially called PAR 56, and as can be seen in Figures 1 and 2, the PCB board (3) is located on a work plane that is
    corresponds to the area of greatest diameter of the spherical cap that defines the housing (1),
    3
    5

    while the cover (5) for the lower closure of the housing (1) that has the electrical connections (6) is placed in a work plane constituted by the area of smaller diameter of said spherical cap. That is, that PCB connection plate (3) and electrical connections (6) are located at a distance approximately equal to the height of said spherical cap defining the housing (1).
    This assembly, as has been said typical and usual, therefore needs to bring the power supply from the mentioned electrical connections (6) to the PCB board (3), which to date is done using the cables (8), the which also access said PCB board (3) from behind in order not to interfere with the light beam.
    In addition, so that said cables (8,9) do not interfere with the distribution on the surface of the PCB board (3) of the LED lamps themselves, two holes (10) are made therein and on the support and dissipation plate (10). ) through which said cables (8,9) access with their corresponding insulator, since the support plate and heat dissipation of the PCB board (3) is usually thermally and electrically conductive, commonly made of aluminum. Once they access the interior, as seen in Figure 2, they bend towards the corresponding connection terminals, to which they are welded.
    This well-known and extended PAR 56 structure, although it fulfills the function for which it has been designed, suffers, however, from some important drawbacks, which derive mainly from two causes mentioned below.
    1. In the first place and as one of the main causes, it is worth noting the fact that the assembly of this type of lamps is manual, which translates into:
    o A high assembly time due to the manual welding process of the cables (8,9). Said time includes not only the one used in the welding itself, but also in the time it takes for the operator to manipulate them, that is, to cut them, set them, pass one of their ends through the holes (10) of the PCB board (3 ), etc. o A greater number of imperfections and welding errors caused by less skilled or distracted operators, which contributes to the difficulty of its realization on the aluminum of the PCB (3) and the proximity of the
    other components due to the concentration of elements on the
    4
    5
    10
    fifteen

    25

    35
    same, components that are also highly sensitive and can be affected by the high heat source that constitutes the welder. o Waste of time derived from the manual manipulation of the welding apparatus and the flux material, among which are those derived from the preparation of the same, its cleaning and conservation, as well as the observance of the norms of prevention of labor risks, that by In addition, they require the use of personal protective equipment that hinder and / or further delay the operation.
    2. Secondly, the use of the cables (8,9) to make the electrical connection, among other reasons due to:
    o Cost of cables, which is added to its handling as already stated. o Introduction of several possible error points due to imperfections, bends, bad insulation, etc.
    o Invasion of the component part of the PCB board (3), which determines the position of said components and, especially, limits the optics of the assembly, closely related to the position occupied by the LED lamps themselves.
    In view of the aforementioned drawbacks, in the current economic situation in which the manufacturing and assembly costs are decisive, a lamp is necessary, whether recessed and / or of aquatic application or not, that optimizes the processes and materials used with the In order to provide these increasingly demanded products with sufficient profitability to compete in the market with guarantees of success.
    Description of the invention
    The lamp of the present invention solves the problems of the state of the art mentioned above, because thanks to its special structure and composition it is able to optimize the process of manual assembly of the different elements that compose it, significantly reducing production costs, which results in a lower final price of the element and, therefore, in greater competitiveness.
    Additionally, the lamp of the invention not only optimizes costs as stated,

    It also solves the technical / safety problems mentioned above, so it alone is already a product of higher quality, guarantees and flexibility in its design, which also benefits the market's image and its competitiveness.
    Specifically, the lamp of the present invention comprises:
    - A body or housing;
    - A PCB board where the electronic components and LED lamps themselves formed by the chip and a primary optic are soldered;
    - A secondary optic formed by a lens that serves as a cover for the assembly and is responsible for "shaping" the light according to the needs of the installation;
    - A cover for the lower closure of the housing that has two electrical connections; Y
    - Screws to connect the PCB board to the housing.
    However, unlike the prior art, in which a pair of cables welded to the PCB were used to supply the power supply, in the lamp that is now recommended the housing comprises two rigid connectors fixed during the procedure of manufacturing it.
    In this way, when the housing is coupled to the PCB or vice versa, not only does the mechanical coupling between them occur, but the electrical connection is made. For this, said PCB board has two holes in which each of the free ends of the rigid connectors fit, making the electrical coupling by means of a simple "plugged in", tongue and groove maneuver.
    Thus, when said rigid connectors are incorporated into the housing during its manufacturing process, either by overmolding or by any other known technique, these are fixedly attached thereto. Thus, during the subsequent assembly process of the lamp, operators only have to worry about joining the two parts, PCB board and housing so that the free ends of the rigid connectors are inserted or clipped into the holes of the PCB board practiced for this purpose.
    This, as is evident, has numerous advantages over the prior art.

    previously commented:
    - The welding is disregarded, so the numerous inconveniences of this technique already mentioned are avoided;
    - Assembly time is saved, optimizing it;
    - The number of elements is decreased; Y
    - The errors of the operation of electrical connection of the PCB board are minimized, practically eliminating them,
    All this results in an easier, faster and safer assembly process that therefore implies a reduction of costs and an improvement of the product, objectives of the present invention.

    Preferred Embodiment of the Invention
    In view of the aforementioned figures 1 to 4, and according to the numbering adopted,

    You can see in them an example of a preferred embodiment of the invention, which comprises the parts and elements indicated and described in detail below.
    Specifically, the lamp of the present invention comprises:
    - A body or housing (1);
    - A PCB board (3) where the electronic components, electrical connection elements and the LED lamps themselves formed by the chip and a primary optic are soldered;
    - A secondary optic formed by a lens (4) that serves as a cover for the assembly and is responsible for "shaping" the light according to the needs of the installation; and
    - Means for attaching the PCB board to the housing, such as screws (7).
    On the other hand, according to a preferred embodiment of the invention, to supply the power supply to the PCB (3), the housing (1) comprises two rigid connectors (11) connected thereto in a solidary manner.
    Said rigid connectors (11), which will be made of a metallic or similar material that guarantees the electrical conductivity, are attached to the housing (1) during its manufacture, either by overmolding, or by any other means and / or intermediate element that guarantees its joint solidarity and the tightness of said union.
    This connection is made in such a way that said rigid connectors (11), which according to a preferred embodiment shown in Figures 3 and 4 are formed by two cylindrical stems, are joined in solidarity with the housing (1) by one of its ends, extending inside it so that its opposite free end is reaching the holes (10) that the PCB board (3) has.
    More specifically, as can be seen in said figures, especially in the preferred embodiment of Figure 4, the rigid connectors (11) are formed by rods whose free end has a section of considerable smaller size than the rest so that the hole (10) of the PCB board (3) through which they are inserted are also small in size.
    On the other hand, at its opposite end, the one that is joined in solidarity with the housing (1),
    5
    10
    fifteen
    twenty
    25
    30
    35
    the rods that make up the rigid connectors (11) have connection means to the power cables which, according to the preferred embodiment shown in the figures, may be constituted by a threaded hole (12) into which the corresponding pins (13 ) for the connection of the power supply cables of the installation where they are placed. However, in another possible embodiment, not shown in the figures, the rigid connectors (11) could accept any other means of connection that allow the connection of the power cables, as well as adopt any geometry that would allow said connection directly, without intermediate element.
    In order to guarantee the power supply of all the elements, the PCB board (3) additionally has two tweezers (14) of conductive material located in or on the mentioned holes (10), so that once the free ends of the rigid connectors (11) pass through the holes (10), these are also subject to mechanical adjustment to said clamps by any conventional method such as "plugged in", tongue and groove, establishing the electrical contact.
    Thus, the rigid connectors (11) have a length such that, during the assembly operation the operator joins the housing (1) with the PCB board (3), the free end of the rigid connectors (11) is introduced by the holes (10) of said PCB board (3), being caught by the clamps (14) ensuring the electrical connection.
    As can be seen in figures 3 and 4, the housing (1) has a mostly hollow spherical cap shape, such that in its opening, located in the area of greatest diameter, it has an internal perimeter flange (15) on the which support the ends of the PCB (3) such that heat dissipation thereof is favored. Likewise, on said internal perimeter flange (15) some of the housings for the fixing screws (7) can be found between both elements, as well as any other similar means that perform the same function.
    According also to a possible embodiment shown in the figures, in order to further facilitate the operation of assembly to the operators and minimize the risk of failure in the connections, the lamp of the invention may include a centering element or positioner (16) which, fixed by the bottom of the PCB board (3), help when introducing the free ends of the rigid connectors (11) through the holes (10) of said PCB board (3),
    It can also condition the relative position of the connectors with respect to the board and
    9
    5
    10
    fifteen

    25

    enabling the maintenance of a certain polarity.
    According to said embodiment, said centering element (16) may have a general shape of a cylindrical base cup such that on its lateral surface it has a guide element (17), such as for example a longitudinal flange, intended to cooperate with a groove (17 ') present in the housing (1), establishing a unique guiding path that facilitates the subsequent plugging or coupling of the said free ends of the rigid connectors (11).
    In addition, said positioning element (16) will comprise in its upper part, on the base on which the guide element is located, fastening means (18) (for example tongue and groove, clipping, etc.) to the PCB board (3) so that it can be fixed to it before coupling between the housing (1) and said PCB board (3).
    In this way, when the operator carries out the assembly, prior to the introduction of the free ends of the rigid connectors (11) fixed in the housing (1) through the holes (10) of the PCB (3), it attaches the element positioner (16) to said PCB board (3) by means of clamping means (18).
    Once the positioning element (16) and PCB board (3) are connected, the operator can make the coupling between the housing (1) and said PCB board (3) using the guide element (17) and the corresponding slot (17 ') , which is simpler and needs less concentration and care than, without any help, introducing the free ends of the rigid connectors (11) through the holes (10) of the PCB (3).
    This is possible because, since said rigid connectors (11) are integral with the housing (1) and the positioning element (16) is fixed to the base plate, the electrical coupling between the rigid connectors (11) and the clamps ( 14) it will be conducted in a directed manner and without the possibility of error in your order or in the possibility of false contact.
    Finally, indicate that the outer face of the housing (1) comprises elements such as projections, breaks in order to maximize the contact area with the fluid to promote heat exchange between it and the PCB board (3 ), that is, to achieve the best possible heat dissipation.
