Abstract:
1. An energy-saving LED street lamp, comprising: lamp body, power supply adapters, constant current actuating device, and LED lamps; said constant current actuating device is connected in series with the output end of the power supply adapter, supplying power to said LED lamps; wherein said energy-saving LED street lamp also comprises auto light-dimmer energy-saving controller, a signal output end of said auto light-dimmer energy-saving controller being connected with constant current actuating device; said LED lamps composing a plurality of working modules, each of said working module being connected with an independent power supply adapter; said auto light-dimmer energy-saving controller comprising a plurality of routes of signal output, each route of signal output end being connected with a constant current actuating device and sequentially controlling the lighting and extinction time of a working module; wherein said lamp body comprises head segment, middle piece and end piece; said head segment being connected with said middle piece, the other end of said middle piece being connected with said end piece; a packing seal being mounted between said head segment and said middle piece; said head segment being connected with said middle piece with fastener; a packing seal being mounted between said end piece and said middle piece; said end piece being connected with said middle piece with fastener; said middle piece being a kind of section material, which has the same cross section in different positions along the length direction of the section material; said section material comprising a basal plate; said basal plate being tabulate; said basal plate extending along the length direction of said section material; said basal plate having two sides: a right side and a wrong side; two side plates being respectively mounted on each of the two edges of said right side; a plurality of heat dissipation wings being mounted on said wrong side; a plurality of LED bulbs being mounted on one side of a heat conducting bottom-board, which forming LED array board, a printed circuit being mounted on said heat conducting bottom-board; the other side of said heat conducting bottom-board which has no LED bulb being cling to said right side of said basal plate of middle piece of said lamp body; the LED street lamp also comprising a plurality of quadratic optical lens; said quadratic optical lens being mounted on a lens bottom-board with a button stand; said lens bottom-board being parallel to said LED array board; each of the said LED bulb being corresponding to one said quadratic optical lens; there being a plurality of support units which have the same height mounted on the side of said lens bottom-board which faces to said LED array board, said support units being linked with said heat conducting bottom-board; said lens bottom-board and said heat conducting bottom-board being connected on the right side of said basal plate with fastener; first cross member being mounted on said head segment, said first cross member being mounted on the end of said head segment which is connected with said middle piece; second cross member being mounted on said end piece, said second cross member being mounted on the end of said end piece which is connected with said middle piece; said first cross member, second cross member, side plates which are respectively mounted on the two edges of the right side of said middle piece, and the right side of said middle piece defining a enclosure together; the right side of said middle piece forming the bottom of said enclosure; said first cross member, second cross member, and said two side plates which are respectively mounted on the two edges of the right side of said middle piece forming four walls of said enclosure; a step used to place lamp-chimney being mounted on the other end of four walls of the enclosure which is far from the bottom; a length of tube being mounted on said head segment; the axes of said tube being vertical to said first cross member; an outlet hole which leads into said tube being mounted on said first cross member, a threaded hole which runs through the wall of said tube being mounted on the side wall of said tube; said head segment, middle piece, and end piece all being made from heat-conducting property material; said LED street lamp also comprising lamp-chimney, said lamp-chimney being mounted on said step, packing washer being mounted between said lamp-chimney and said lamp body; said LED array board also comprising a plurality of LED subsidiary array boards; a team of LED lamps being mounted on each of the LED subsidiary array board; each of the LED subsidiary array board being connected on the right side of said basal board of middle piece with fastener; correspondingly, lens bottom-board also comprising a plurality of subsidiary lens bottom-boards, a team of quadratic optical lenses being mounted on each of the subsidiary lens bottom-board, each of the subsidiary lens bottom-board being connected on the right side of said basal board of middle piece with fastener; said constant current actuating device being mounted on the end of the middle piece which is closer to the head segment of the lamp body, a heat-actuated device of an over heat thermostat being mounted on said heat conducting bottom-board.
