The LED street lamp reflector is characterized in that: the top is provided with aplurality of lugs and the lugs are integrated with the top; the lugs are arranged in a direction between the two inclines, a line of lamp holders are arranged in the same direction as the lugs between two neighboring lugs, and all the lamp holders are arranged between two lugs; a middle portion of the lug is straight, side faces of other portions of both ends are curved; one side face of the lugis higher than the other side face, and the protrusion forms a boss on an upper surface of the lug; and the upper surface of the curved portion of a lug side is continuous rhombic. The lug arranged onthe top can reflect irradiating light of the LED lamp, thus improving illumination and uniformity of beams and increasing irradiation range.

The invention discloses a reflecting cup pedestal used for connection with a substrate. The reflecting cup comprises a pedestal provided with a reflecting cavity, and a locating hole and a locating bayonet which are arranged on the upper surface of the pedestal, wherein the substrate is further provided with a locating installation part used for locating the pedestal and the substrate, a fixed connection part used for fixedly connecting the pedestal and the substrate, and a lens locating installation groove used for coinciding a lens and an axis of the pedestal. The reflecting cup has the advantages of simple structure, low cost and good secondary light distribution effect, the pedestal and the substrate are quickly and accurately installed, inclination can be prevented after a secondary light distribution component is connected to the substrate, and the pedestal is vertical to the substrate, so that light ray can be irradiated far enough, thus the reflecting cup has good illuminating effect.

The invention relates to an array optimization layout method for improving positioning accuracy of a single-star interference source. The method is characterized in that in order to meet the requirement of high precision single-star interference positioning applications, the correlation coefficient feature is introduced into an array layout objective function, independence and uniqueness of direction vectors of the antenna array in the direction finding range are evaluated, and the layout structure of antenna array elements is optimized.
