The invention discloses an LED (light emitting diode) illumination street lamp which comprises an aluminum alloy heat radiator and LED lamp bars installed on the aluminum alloy heat radiator, wherein the aluminum alloy heat radiator comprises a base plate and a plurality of bar-shaped heat radiation barriers; the base plate is provided with air counterflow holes; the right end of the base plate is fixedly connected with a mounting lower splint; the upper part and the lower part of the mounting lower splint are symmetrically provided with nuts and bolts for connection; the lower side of the mounting lower splint is provided with a power supply box; the base plate is arch-shaped; the plurality of bar-shaped heat radiation barriers are fixedly connected to the lower end of the base plate; the base plate is uniformly provided with LED lamp bar caulking grooves; the LED lamp bars are installed in the LED lamp bar caulking grooves; the air counterflow holes are arranged at two sides of each LED lamp bar caulking groove; the base plate is also provided with air interflowing and water leakage holes which are in intersection with the air counterflow holes. The LED illumination street lamp provided by the invention is simple in structure and is novel in design, and has a large illumination covering range; the defects of small illumination range and poor heat radiation effect in the prior art can be solved effectively; and moreover, the appearance is beautiful.
Description
technical field [0001] The invention belongs to the technical field of lighting lamps, and in particular relates to an LED lighting street lamp. Background technique [0002] Because of its high luminous efficiency (energy-saving efficiency can reach more than 90%), LED lighting street lamps have been paid more and more attention by countries all over the world since its birth. Now LED lighting street lamps have become the main research and development direction of people. Existing LED street lamps generally install LEDs on a flat substrate, and the LEDs form a dot matrix on the flat substrate, which has the disadvantages of limited luminous coverage, difficult heat dissipation, and old-fashioned shape during actual use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an LED lighting street lamp with simple structure, novel design and large lighting coverage, which can effectively solve the problems of small ligh...
