Modular LED street lamp

Abstract

The invention relates to a modular LED street lamp. Each single module comprises screw rods, a convex ring, a concave ring, semicircular concave grooves, elastic rubber rods and fastening pressing strips. Modules are connected in an overlapping way. The connection surface of the adjacent two modules is divided into a part at the top and a part at the bottom, wherein one of the two parts is concave, and the other part is convex. The left surface and the right surface are concave and convex oppositely. The body of the modular LED street lamp, which is perpendicular to the contact and connection surface of adjacent two modules, is externally and longitudinally provided with a locking hole which penetrates through the whole modules, and the locking holes are penetrated by the rods and are fastened by nuts one two ends. The connection surface of adjacent two locking holes is provided with the convex ring and concave ring which are used for guiding and limiting. The left contact and connection surface and the right contact and connection surface of the adjacent two modules on the upper part are respectively provided with one semicircular concave groove, and the two semicircular concave grooves are opposite to each other and can be combined together to form a full circle. One elastic rubber rod whose diameter is larger than the diameter of each of the semicircular concave grooves is filled in each semicircular concave groove. Two sides of the horizontal line connecting the multiple modules are respectively provided with one fastening pressing strip for limiting.

Description

technical field [0001] The invention belongs to the field of semiconductor lighting, in particular, relates to a semiconductor LED street lamp Background technique [0002] LED has the advantages of small size, high efficiency, and long life. However, when LED is used in street lamps and other lighting equipment, in order to ensure its long life advantage, heat dissipation design must be carried out. In this way, necessary heat dissipation devices must be assembled on the lamp body. , so that the cost of the lamp body rises rapidly. Especially when the die-casting lamp body is used, the volume and complexity of the mold are greatly increased due to the addition of the cooling device, resulting in a doubled increase in cost. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a modular LED street lamp, which decomposes a large overall mold into small molds, and combines a plurality of small die-casting parts into a larg...
