Also be provided with a stage clip between power pack and screw thread stop bit joint, described power pack one end is open, is stamped the power pack cover plate on it, cover plate links to each other with an end of fin, the other end of power pack is provided with perforate, and the perforate outer surface is a circle projection, the projection stage clip that is located by connecting;
Described power pack seals on the end end face and also is provided with the stop bit projection;
Described screw thread stop bit joint is provided with the depression that is used for embedded stage clip away from screw thread one end;
Also be provided with on the described depression inwall and be used for the alignment pin that matches with power pack end face stop bit projection;
Alignment pin on the described screw thread stop bit joint sidewall is for being symmetrical arranged, and alignment pin is connected with spiral stop bit joint and is provided with the boss that a circle cooperates with locating ring inner card cage sidewall between the stage clip one end end face;
Described fin links to each other with the LED matrix unit, also is provided with water proof ring therebetween;
Described fin is made its end face by aluminium section bar and is become half elliptic;
Described fin fin becomes straight up, and there is fluting its side;
The LED lens are stamped on described LED matrix unit surface, and the LED lens are the eyeglass matrix of whole corresponding LED herein.
Than common LED street lamp, the beneficial effects of the utility model are by the landing nipple of LED street lamp jockey, the cooperation of position-arresting ring, realized the level inclination of the change light source that this kind LED street lamp still can be easy after installation, and the collocation of this kind LED street lamp half elliptic fin, water proof ring and PC lens, thereby further rationalize the LED lamp post structure.
