FIELD OF THE INVENTION 
       [0001]    The present invention relates to the field of light fixtures. More particularly, the invention relates to means for connecting a light fixture to a wall, ceiling, and so on. 
       BACKGROUND OF THE INVENTION 
       [0002]    Presently, due to the existing installation technologies of wall light fixtures, the base of an installed light fixture protrudes from the wall, resulting in a defective esthetic appearance of the light fixture. 
         [0003]    Furthermore, existing technologies do not provide a solution for adjusting the angle of an installed light fixture with regard to the wall on which it is installed, in order to be vertical, and essentially the result depends on the skill of the installer. 
         [0004]    It is an objective of the present invention to provide a solution for the above-mentioned and other problems of the prior art of installing light fixtures. 
         [0005]    Other objectives and advantages of the invention will become apparent as the description proceeds.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0032]    In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In some instances, well-known methods, procedures, components and circuits have not been described in detail, for the sake of brevity. 
         [0033]    The term Light Fixture Wall Foundation (LFWF) refers herein to a device that intermediates between a light fixture and a wall. Thus, instead of connecting a light fixture to the wall directly, the LFWF is installed in the wall, and the light fixture is connected to the LFWF. A LFWF is marked herein by reference numeral  2 . 
         [0034]      FIG. 1  schematically illustrates a light fixture installed in a wall using a light fixture wall foundation (LFWF), according to one embodiment of the invention. 
         [0035]      FIG. 2  is an exploded view that schematically illustrates the parts of the light fixture illustrated in  FIG. 1 . 
         [0036]    In this example, the light fixture is an outer light fixture. 
         [0037]    The LFWF illustrated in these figures comprises a “junction box”  4 , which is a box made of rigid, preferably non-conductive material (such as plastic) or coated by non-conductive material. 
         [0038]    The junction box is fixed into the wall, e.g., while casting. Another example of fixing a junction box into a wall is by drilling a hole into the wall, placing the box therein, and filling the remaining space with material such as cement, plaster, and the like. 
         [0039]    The junction box comprises an opening  20 , the size of which corresponds to the size of a connection box  12 . The contour of the connection box corresponds to that of opening  20  of the junction box, but it&#39;s dimensions are smaller than those of opening  20  of the connection box, thereby leaving a gap (space)  28  therebetween. The objective of the gap is to allow changing the position of the connection box with reference to the junction box, or in other words, to provide some degree of freedom in placing the connection box with reference to the junction box, by so having the connection box embedded in the wall with its surface being as one with the wall. The connection box&#39;s form does not necessarily have to be square, as illustrated, but may also be circular, elliptic, rectangular, and so on, corresponding to the form of the opening of the junction box. 
         [0040]    According to one embodiment of the invention, a frame  32  surrounds opening  20 . The frame comprises one or more apertures  26 , through which a bolt may be passed. This is useful for fitting during casting. 
         [0041]    The form of the base of light fixture  18  corresponds to that of connection box  12 , allowing one to fit into the other. In this example, the size of base  14 , which is in box form, enables embedding the box-form base into the connection box&#39;s box-form. Base  14  can be secured to the connection box by securing means such as an adherent, bolts, and so forth. 
         [0042]    Thus, the base of the light fixture is secured to the connection box, and the connection box is secured to the junction box. In other words, base  14  is inserted into connection box  12 , and connection box  12  is inserted into the junction box  4 . Since there is a gap between the connection box and the junction box, a user can adjust the position of the connection box with regard to the junction box, secure the connection box in this position, and then secure the base of the light fixture to the connection box. 
         [0043]    Numeral  8  denotes a space in the junction box, for storing a transformer (seen in  FIG. 4  and marked by numeral  10 ), as some types of light fixtures include a transformer. Thus, according to embodiments of the present invention, the space for housing a transformer is already available in a LFWF. 
         [0044]    A latch  24  can be used when placing the junction box inside a plaster wall and the like. If the junction box is installed while casting a wall, the latch may be omitted. 
         [0045]    An opening  6  in the walls of the junction box allows passage of electric power into the box space. 
         [0046]      FIG. 3  is a cross section view that schematically illustrates the LFWF of  FIG. 1  installed in a wall, according to one embodiment of the invention. 
         [0047]    The wall, in this case a cast, is marked by reference numeral  36 . As illustrated, the junction box  4  was installed inclined, and if the light fixture  18  had been connected to the junction box in the prior art technology, it would have been stand-inclined. However, since the light fixture is connected to connection box  12 , as illustrated in this figure, the position of the connection box with regard to the wall can be adjusted to straight despite the fact that the junction box stands inclined. 
         [0048]    As illustrated, gap  28  between the connection box and the junction box is filled with fixation substance  38 , such as a fluid that hardens upon drying. For example, plaster, adherent, cement, and so on will do. 
         [0049]    The term spotlight refers herein to a light fixture that comprises a receptacle for the lamp, such that the lamp does not pass beyond the edges of the receptacle. The receptacle may be in the form of a halved sphere, halved ellipse, halved square, and so on. 
         [0050]      FIG. 4  is a cross section view that schematically illustrates a spotlight installed in a LFWF, according to one embodiment of the invention. 
         [0051]    The spotlight, marked herein by numeral  16 , is in the form of a square. The sectioned parts are connection box  12  and junction box  4 . The illustration shows the location of transformer  10  in the junction box, and the wires that pass electricity from the transformer to the 12V bulb  42  of the spot. 
         [0052]    The present invention provides the following advantages over the prior art:
       drilling is not required to install a light fixture;   easier installation;   the light fixture extends directly from the wall (i.e., the base is hidden), providing an improved appearance in comparison to the prior art;   higher security level in comparison with the prior art, as wire connections are inside the junction box;   the junction box already comprises space for placing a transformer;   the invention can be implemented in concrete walls, brick walls made of construction blocks, Ittong™ blocks (trademark of a porous construction block), plaster, and the like.       
 
         [0059]    Preferably, the dimensions of the LFWF are as follows:
       The inner size of the junction box is about 7.4×7.4 cm. This enables easy insertion and extraction of a transformer in and out of the junction box.   The size of space  8  in which a transformer is placed is about 4×7.4 cm, which suits for the presently common light fixture transformers with no interference to a presently common spotlight.   The outer size of connection box  12  is about 7×7 cm. This suits for the presently common spot lights.   Frame  32  protrudes from the outer contour of the junction box by 6 mm. This provides suitable holding in a plaster wall, a ceiling and also in a casting.
