Modular LED street lamp

Abstract

The invention relates to a street lamp using a light emitting diode (LED) as a light source, in particular a modular LED street lamp. The modular LED street lamp comprises a lamp holder in which a control circuit is arranged, wherein the rear end of the lamp holder is provided with a connecting bin connected with a lamp pole; and two sides of the front end of the lamp holder are connected with a pair of parallel side beams, the upper and lower edges of the opposite inner sides of the pair of side beams are provided with a longitudinal slot respectively, a lampshade positioned at the bottom and a cover plate positioned at the top are inserted into the slots, a plurality of LED light source modules are longitudinally arranged in a cavity between the cover plate and the lampshade, and the cover plate and the front end of the lampshade are connected with plugging pieces. Because of the adoption of a modular light source structure, the street lamp can adapt to the requirements of different illumination ranges and intensities by changing the number of the LED light source modules; the street lamp has compact integral structure, and is convenient to manufacture and install; and moreover, by adopting the integrated encapsulated LED light source, the realization of the modular structure is convenient, and the light source part is conveniently subjected to centralized waterproof encapsulation.

Description

technical field [0001] The invention relates to a street lamp using LED as a light source, in particular to a modular LED street lamp. Background technique [0002] Most of the existing LED street lamps are specially designed with specific specifications according to the needs of light intensity. The number of light sources and heat dissipation structure are designed according to specific requirements. After the design of a product of one specification is completed, its main components are difficult to apply to other specifications. The interchangeability of products and parts is poor. In the process of manufacturing and installation, it is impossible to adjust the range and intensity of light on the basis of the original product according to changes in actual use needs, which increases the investment in molds and equipment in the product manufacturing process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mo...
