     DETAILED DESCRIPTION OF THE INVENTION 
     The above described drawing figures illustrate the invention, a model lighthouse apparatus comprising a box structure 10, as best seen in FIGS. 1 &amp; 2, providing an interior space 20 (FIG. 3) enclosed within the box structure 10 and an upwardly facing top mounting plate 30; a scale model hollow lighthouse structure 40 (FIG. 2) fixed to the mounting plate 30 and extending upwardly therefrom, the lighthouse structure 40 providing a lighthouse tower 42 with a tower window means 44 therein, and atop the lighthouse tower 42, a beacon room 46 with a beacon room window means 48 therein; a elongate and linear lighting boom 50 fixed at a proximal end 52 thereof to the top mounting plate 30 and extending upwardly therefrom within the lighthouse structure 40, the lighting boom 50 comprising a first tube means 54 engaged with a second tube means 56 such that a length L1 of the joint first and second tube means is extensible, as shown in FIG. 6; a tower lamp means 60 joined medially to the lighting boom 50 and positioned so as to illuminate the interior 43 of the lighthouse tower 42 and the tower window means 44; and a beacon room lamp means 70 joined to a distal end 58 of the lighting boom 50 and positioned so as to illuminate the interior of the beacon room 46 and the beacon room window means 48. 
     The first 54 and second 56 tube means are preferably telescopically joined as shown in FIG. 6, and further provide a means for fixing 57 the length L1 thereof, such as the screw shown, the lighting boom 50 coaxially incorporating an electrical power line 59 therewithin (FIG. 5) for conducting power from the box structure 10 to the beacon room lamp means 70. 
     Preferably, an opaque shading washer 51 is frictionally joined near the distal end 58 of the lighting boom 50, and adapted in size, shape and material, as shown, to functionally exclude light exchange between the lighthouse tower 42 and the lighthouse beacon room 46. Washer 51 is preferably made of a disk shaped rubber material so that it may be forced to comply in shape to any surface against which it is pressed. In this manner, the light within the tower 42 can be adjusted as to brightness independently from that of the beacon room 46 as in a conventional lighthouse. 
     In one embodiment of the invention, as seen in FIG. 6, the electrical boom 50 is adjustable in length to match the corresponding dimension of the lighthouse structure 40. The appropriate length of the electrical power line 59 being drawn from or into the interior space 20 of box structure 10 as necessary to satisfy the adjusted boom length L1. It is shown, here, that the tubes 54 and 56 are easily moved one within the other and fixed in total length by fixing means 57. 
     In another embodiment of the invention, as seen in FIG. 3, the second tube means 56 is rotationally driven by a prime mover 80 mounted within the box structure 10, i.e., second tube means 56 is functionally mounted to prime mover 80, as shown in FIG. 4 and is free to rotate therewith. First tube means 54 is fixed in place and is supported by nuts 50N which are threaded onto first tube means 54, as shown. FIG. 5 also clearly shows such an arrangement, where, preferably, second tube means 56 and electrical power line 59 rotate together within stationary first tube means 54. Washer 51 is preferably mounted on stationary first tube means 54 so as to remain stationary, while lamp means 70 is mounted at the end of second tube means 56 so as to rotate therewith. 
     In a still further embodiment of the invention, as shown in FIGS. 7 and 8, both the adjustment of length L1 as well as rotation of beacon room lamp means 70 are combined. To accomplish this, a third tube means 54A is slidably engaged with second tube means 54 such as by the engaging spline shown, or similar means, so that both tube means 54 &amp; 54A are forced to rotate together, but tube means 54A is telescopically positionable relative to tube means 54 so as to adjust length L1. The connection of electrical power to a rotating member is well known in the art, and is accomplished here, through the use of a rotational electrical power coupler 90 such as the type commonly used to prevent telephone handset wires from becoming wound up or snarled. Such a coupler 90 is preferably used at the proximal end 52 (FIG. 7) of the lighting boom 50 for conducting power to the electrical power line 59. In this embodiment, washer 51 is mounted onto bearing race assembly 51A so as to remain stationary although tube means 54A is rotating. Clearly, lamp means 70 is secured to tube assembly 54A so as to rotate therewith. 
     In use, the lighting boom 50 is adjusted to the necessary length L1 for any particular lighthouse structure 40 and is fitted therein with nuts 50N holding boom 50 tightly to mounting plate 30. Length L1 is set so that beacon room lamp means 70 is positioned opposite to beacon room window means 48, and directed as shown in FIG. 3 for throwing light directly out of window means 48 as with a commercial lighthouse. Lamp means 60 may be adjusted and positioned to be opposite window means 44, but may be place away from window means 44 for achieving indirect light effects in the tower. Both lamp means 60 and 70 are interconnected by wires to a power supply means (not shown) in interior space 20, and may comprise a battery, or a DC rectification and transformer means, as is well known in the art. Prime mover 80 is preferably a timer type motor and is adapted for appropriate speed reduction through the use of gear means 82, shown in FIG. 4. Phase speed control or rheostat speed control may be used to adjust the rotational speed of lamp means 70. Likewise, phase control or a resistor divider network may be used, for example to adjust lamp intensities as is well known in the art. When external power is used, a socket S1 (FIG. 2) is supplied for accepting an incoming jack (not shown). Many configurations of control may be applied to the present invention such as shown in FIGS. 1 and 2. In FIG. 1 socket S1 is shown as well as an on-off switch S2. For the rotational embodiment, in FIG. 1, L2 and L3 adjust the brightness of lamp means 60 and 70 respectively, while R1 adjusts the rotational rate of lamp means 70 through prime mover 80. For the non-rotational embodiment, R1 adjusts the rate of a strobe device so that lamp means 70 goes through an illumination cycle from full off to full bright and then back to full off in a repeating fashion in order to simulate a rotating beacon. Electrical circuits for the accomplishment of the above control are so well known in the art as to be unnecessary to describe here in further detail. Such circuits may be easily fitted into and mounted within interior space 20. 
     While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
