Title:
MODULAR LED STREET LAMP AND LED LIGHT SOURCE MODULE
Document Type and Number:
WIPO Patent Application WO/2014/082470
Kind Code:
A1
Abstract:
Disclosed is a modular LED street lamp, comprising an electrical cavity (10), a lamp arm (40), two supporting pipes (20), an end cover (30) and a plurality of LED light source modules (50). The plurality of LED light source modules (50) are fixed between the two supporting pipes (20). At least one of the LED light source modules (50) comprises a rectangular light-transmitting board (51) with a plurality of lenses (511) formed thereon; a protective plate (52) snugly adhered to an upper surface of the light-transmitting board (51); a circuit board (53) fixed below the light-transmitting board (51); and a radiator (54) fixed below the circuit board (53), the radiator comprising a first heat conducting plate (541) snugly adhered to a lower surface of the circuit board (53), two second heat conducting plates (542) extending from the lower surface of the first heat conducting plate (541) and a third heat conducting plate (543) connected to the ends of the two second heat conducting plate (542). The radiator (54) of the present LED street lamp has a large area of heat dissipation and a high heat dissipation efficiency; in addition, when it is required to increase or decrease the number of the LED light source modules (50) for the purpose of increasing or reducing the power of the LED street lamp, all that is needed is exchanging with lengthened or shortened supporting pipes (20), thus enabling a range of power of the street lamp at very low costs.
