The first light source is disposed on the front surface portion of the base body. The cover body has a front opening portion connected to an inside of the cover body, a rear cover portion, top and bottom edge portions provided between the front opening portion and the rear cover portion, and two side portions. Each focus controller is installed on each convex lens in the inner space portion of the cover body and configured for controlling a distance between the corresponding second light source and convex lens and providing a light beam ranging from a directional narrow focused spot light to a wide spreading flood light. ## Claims ### Claim 1 A focusable lighting system comprising: a base body having front and rear surface portions, top and bottom surface portions, and two side surface portions; a first light source disposed on the front surface portion of the base body; a cover body having a front opening portion connected to an inner space portion of the cover body, a rear cover portion, top and bottom edge portions provided between the front opening portion and the rear cover portion, and two side portions; one or more second light sources, each of which being disposed on a top surface of a first cylindrical platform in the inner space portion of the cover body so as to illuminate a front side of the front opening portion through the front opening portion; one or more convex lenses, each of which having a second cylindrical platform being installed on each of the one or more second light sources; and a plurality of focus controllers, each of which being installed on each of the one or more convex lenses in the inner space portion of the cover body and configured for controlling a distance between the corresponding second light source and convex lens and providing a light beam ranging from a directional narrow focused spot light to a wide spreading flood light. ### Claim 2 (depends on 1) The focusable lighting system of claim 1, wherein each of the one or more focus controllers is controlled remotely from outside. ### Claim 3 (depends on 2) The focusable lighting system of claim 2, wherein each of the one or more convex lenses engages with a corresponding one of the one or more second light sources through male and female threads. ### Claim 4 (depends on 2) The focusable lighting system of claim 2, further comprising: a hinge tube rod having one end fixed to the cover body and another end to an outer circumferential surface of which a hinge gear is fixed; a cover base board having a horizontal plate portion, two vertical side plate portions extending from two edge portions of the horizontal plate portions; two rod holes provided through the two vertical side plate portions; a connecting rod queued through the two rod holes and a center through-hole of the hinge tube rod, connecting rotatably the cover body to the cover base board; and an open-close motor having a motor rod rotatably anchored to one of the two vertical side plate portions and a motor gear that is configured to engage the hinge gear and close or open the cover body over the front surface portion of the base body. ### Claim 5 (depends on 2) The focusable lighting system of claim 2, further comprising a circuit board having a first circuit portion for operating the first and second light sources and a second circuit portion for operating an open-close motor and a swiveling motor. ### Claim 6 (depends on 3) The focusable lighting system of claim 3, wherein the male threads are provided on an outer circumferential side surface of the first cylindrical platform and the female threads are provided on an inner surface of the second cylindrical platform, so that the male threads and the female threads engage and rotate against each other so as to change the distance between the second light source and the convex lens. ### Claim 7 (depends on 4) The focusable lighting system of claim 4, further comprising: a connector rod extending downwards vertically from the cover base board into the base body; a swiveling gear fixed to a lower end of the connector rod; and a swiveling motor provided in the base body and having a motor gear engaging the swiveling gear, which are configured to swivel the cover base board and the cover body together by rotating the connector rod. ### Claim 8 (depends on 5) The focusable lighting system of claim 5, wherein the circuit board further comprises a third circuit portion for communicating with an remote control through a wired or wireless communication. ### Claim 9 (depends on 6) The focusable lighting system of claim 6, wherein each of the plurality of focus controllers comprises: a screw portion provided on an outer surface of the second cylindrical platform of the convex lens; and one or more gears, at least one of which engaging the screw portion, wherein at least one of the one or more gears is rotated by an electric motor. ### Claim 10 (depends on 9) The focusable lighting system of claim 9, wherein each of the plurality of focus controllers is configured to rotate one or more convex lenses. ### Claim 11 (depends on 10) The focusable lighting system of claim 10, wherein both ends of a connecting rod are fixed to two vertical side plate portions with two handle knobs. ### Claim 12 (depends on 1) The focusable lighting system of claim 1, wherein each of the one or more focus controllers is controlled manually. ### Claim 13 (depends on 12) The focusable lighting system of claim 12, wherein each of the plurality of focus controllers is disposed in the inner space portion of the cover body, installed on the second cylindrical platform of a corresponding convex lens, and configured for controlling a distance between the corresponding second light source and convex lens and providing a light beam ranging from a directional narrow focused spot light to a wide spreading flood light by rotating an outer handle portion of the corresponding convex lens manually. ### Claim 14 (depends on 12) The focusable lighting system of claim 12, wherein each of the one or more convex lenses engages with a corresponding one of the one or more second light sources through male and female threads. ### Claim 15 (depends on 12) The focusable lighting system of claim 12, wherein each of the plurality of focus controllers is disposed in the inner space portion of the cover body, installed on the second cylindrical platform of a corresponding convex lens, and configured for controlling a distance between the corresponding second light source and convex lens and providing a light beam ranging from a directional narrow focused spot light to a wide spreading flood light by pushing in or out the corresponding convex lens manually. ### Claim 16 (depends on 14) The focusable lighting system of claim 14, wherein the male threads are provided on an outer circumferential side surface of the first cylindrical platform and the female threads are provided on an inner surface of the second cylindrical platform, so that the male threads and the female threads engage and rotate against each other so as to change the distance between the second light source and the convex lens. ### Claim 17 (depends on 15) The focusable lighting system of claim 15, wherein each of the one or more convex lenses engages with a corresponding one of the one or more second light sources through a side screw handle provided on a first cylindrical platform of the convex lens and a side screw provided along a rectangular cutout through the second cylindrical platform of the convex lens, so as to be configured that the side screw handle of the convex lens is latched at a notch of the side screw, providing a specific interval between the convex lens and the second light source. ### Claim 18 (depends on 15) The focusable lighting system of claim 15, wherein the first cylindrical platform of the convex lens is provided along an edge portion of the convex lens.
