Abstract
The utility model provides a light-emitting diode (LED) street lamp which brings convenience to heat dissipation and maintenance. A structure of the lamp achieves a natural convective circulation, takes away heat dissipated during work of the LED street lamp, and prolongs service life of the LED street lamp. The LED street lamp is convenient to assemble and maintain due to a fixing mode. A power source (9) and a radiator (5) are separated through a power source box (8) and a division plate (10). Heat dissipated during work of an LED (6) light source and the power source (9) can not influence elements of the power source (9), and therefore the service life of the power source (9) is guaranteed. An upper shell (1) of the lamp is an arc-shaped surface which is high in the middle and low in two sides. Therefore, feces of worms and birds, dusts or other sundries can drop downward due to the effect of rain wash and wind force after dropping on the upper shell (1) of the lamp so that maintenance cost of the lamp is reduced.

Further, said louvre 14 is the consistent ellipse of size, rectangle, square or circular.
Further, said louvre 16 is the consistent ellipse of size, rectangle, square or circular.
Further, said louvre 14 is 5 ~ 8, and left-right symmetric is distributed in lower casing, and about in the of 13 two ends.
Further, said louvre 16 is 25 ~ 30, and left-right symmetric is distributed in lower casing 13 both sides.
The beneficial effect that the present invention obtains is: this LED lamp post structure is than present like product; Under the prerequisite that manufacturing cost does not improve basically; The heat dispersion of LED light fixture is greatly improved; The job security of LED light source, reliability and stability are able to guarantee, thereby have improved service life.
The fixed installation structure of LED street lamp because adopt rotating seat 7 and buckle 2 fixing, and be provided with support bar 4, direct free-hand opening in maintenance process makes the installation and maintenance facility more of light fixture.
In addition,, after the worm birds droppings just, dust or other foreign material drop on light fixture upper casing 1, can under the effect of rain drop erosion and wind-force, drop downwards, reduce the maintenance cost of light fixture because high both sides are low in the middle of the light fixture upper casing 1.
