The supporter both sides of described lampshade have the hole, and the lamp body two ends of two lamps of front and back side that flexibly connect with the supporter both sides of lampshade are that the hole by the supporter both sides of adjusting screw(rod) and lampshade flexibly connects (connector is an adjusting screw(rod) when flexibly connecting at this moment).

The hole of the supporter both sides of described lampshade is an arcuate socket.

Described lamp body can be an integral body, also can be to comprise lamp housing and upper and lower sides cover plate, and the upper and lower sides cover plate is fixed in the lamp housing two ends.

Described LED lamp group mainly comprises substrate, LED lamp, convex lens, and described substrate is installed on the lamp housing front side, is fixed with described LED lamp on it, and the LED lamp is electrically connected with power supply box, and described convex lens is installed on the substrate and with described lamp housing front side and is fixed by securing member.

In order to strengthen the radiating effect of LED street lamp, described lamp housing left and right sides outer surface is provided with projection, has increased area of dissipation.

Described LED lamp is that welding is fixed and is distributed on the substrate.

The material of described lamp housing is an aluminium, and substrate is an aluminium base.

Described securing member is a screw.

The power supply box of the utility model LED street lamp is provided with safety measures such as antisurge protection, short-circuit protection; and in acting in collusion to make each other's confessions circuit, each has adopted AC/DC single channel current constant mode; guarantee that the electric current in each loop and voltage constant are at LED lamp best operating point; prolonged the service life of LED lamp; delay light decay, reduced maintenance cost.

The utility model compared with prior art has following beneficial effect:

1) because the principle of LED street lamp utilization adjusting screw(rod) adjustable-angle, its adjusting screw(rod) can be rotated freely in the arcuate socket of the supporter both sides of lampshade, regulate proper angle;

2) because the material of lamp housing, substrate is an aluminium, and lamp housing left and right sides outer surface is provided with projection, increased area of dissipation, and the heat radiation characteristics of the aluminium that made full use of make radiating effect reach the most idealized;

3) in illumination design, take into full account the characteristics of road lighting, adopted secondary optics to handle, on the LED lamp, convex lens has been installed, made the light source refraction and accumulate on the target, be increased in the illumination uniformity on the path area.
