Abstract

The invention relates to a LED street lamp, in particular to an expandable LED street lamp and a method for expansion of luminous surface of LED street lamp. The LED street lamp comprises a lamp body equipped at the top of a lamp post of the LED street lamp. The invention is characterized in that a plurality of dismountable and independent LED working modules are equipped in the lamp body, each working module is composed of a piece of heat conducting substrate and a LED lamp bulb equipped on the front side of the LED heat conducting substrate, and a printed circuit is disposed on the heat conducting substrate; the lamp body also comprises a plurality of independent constant current driving devices, one constant current driving device corresponds to one LED working module, and the constant current driving devices supply power to the LED working modules. The method for expansion of luminous surface of LED street lamp comprises adding the LED working modules. The invention provided an expandable LED street lamp and a method for expansion of luminous surface of LED street lamp.

Description

technical field [0001] The invention relates to an LED street lamp, in particular to an expandable LED street lamp and a method for expanding the luminous area of ​​the LED street lamp. Background technique [0002] The history of LED development has been decades, but the application in the field of lighting is still a new technology. With the rapid development of LED technology and the gradual improvement of its luminous efficiency, the application market of LED will be more extensive; in the context of rising concerns about global energy shortages, the prospect of LED in the lighting market has attracted global attention and has been recognized by the industry. It is believed that it will become the most promising market in the next 50 years, and it is the product with the greatest potential to replace incandescent lamps, tungsten lamps and fluorescent lamps. The light-emitting area of ​​street lamps in the prior art, including LED street lamps, is constant unless the ent...
