Abstract
The invention provides a light emitting diode (LED) street lamp which is convenient for heat dissipation and maintenance. The structural design of the lamp can form natural convective circulation, carries away heat dissipated from operation of the LED street lamp, and prolongs the service life of the LED street lamp. A fixing method of the lamp is more convenient for assembly and maintenance. A power source (9) and a heat radiator (5) are isolated by a power source box (8) and a spacer plate (10), and heat generated by operation of an LED light source (6) and heat generated by operation of the power source (9) will not influence elements of the power source (9), thereby ensuring the service life of the power source (9). Since an upper shell (1) of the lamp is in a convex arced shape, feces excreted from insects and birds, dusts or other impurities dropped on the upper shell (1) of the lamp can fall off under the action of rainfall erosion and wind power, thereby lowering the maintenance cost of the lamp.

Background technology
The LED light source is a kind of cold light source; Have advantage such as efficient, energy-conserving and environment-protective, consumed power is low, start-up time is short, long service life and be applied to gradually in the city illumination engineering, particularly the application in street lamp oneself become the focus of domestic and international semiconductor lighting industry in recent years.Yet existing LED street lamp in the course of the work, and the efficient of led light source is far from reaching 100%, and wherein part energy converts heat to; Heat concentrates in the small-sized chip; Make that the temperature of chip internal is increasingly high, can cause that the concentrating of thermal stress, chip light emitting efficient and fluorescent material swash problems such as penetrating decrease in efficiency, directly influence the life-span of LED; Quicken the light decay of LED, so how to improve the major issue that the radiating effect of great power LED road lamp becomes Design of Luminaires.The employed heat abstractor of existing great power LED light fixture oneself through being difficult to satisfy the demand that the LED lamp power constantly promotes because the restriction of radiator structure, itself and air contact-making surface are limited, make the defective of this radiator structure influence the service life of LED greatly.Therefore, be badly in need of improving on high-power LED lamp, carrying out radiator structure so that heat distribute the junction temperature when effectively reducing LED work in time.On the other hand, oneself has the road lamp structure all is to adopt the screw fixed installation, and dismounting is inconvenient, is unfavorable for safeguarding.
Summary of the invention
Problem to be solved by this invention is: a kind of LED street lamp is provided, is used to solve the LED street lamp because difficult problem is dismantled, safeguarded to the difficult problem of heat radiation and the existing LED street lamp that caused by the restriction of LED lamp cooling structure.
In order to solve the technical problem that the present invention proposes; The present invention realizes through following technical scheme: a kind of LED street lamp, comprise upper casing 1, support bar 4, radiator 5, led light source 6, rotating seat 7, power pack 8, power supply 9, dividing plate 10, power supply lid 11, lens 12, lower casing 13, and said upper casing 1 rear end is provided with buckle 2; Said lower casing 13 rear ends are provided with buckle groove 15; Wherein: upper casing 1 front end also is provided with strip groove 3, and the end of strip groove 3 is stepped, is left-right symmetric and distributes.Form heat dissipation channel 17 between the said strip groove 3; Lower casing is provided with louvre 14 in two ends about in the of 13, and both sides are provided with louvre 16, is provided with dividing plate 10 between said power supply 9 and the radiator 5; Power supply 9 and radiator 5 are separated; Said upper casing 1 is provided with support bar 4 with lower casing 13 right sides, and said upper casing 1 rear end buckle 2 is buckled in lower casing 13 rear end buckle grooves 15, and upper casing 1 and lower casing 13 are fastened.
Further, said louvre 14 is the consistent racetrack of size, ellipse, rectangle, square or circular.
Further, said louvre 16 is the consistent racetrack of size, ellipse, 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.
