Specific embodiment

Please refer to figure, in the utility model embodiment, a kind of municipal administration is with from heat dissipation illumination LED street lamp, including shell 1, peace Fill seat 2 and glass lamp shade 3；The glass lamp shade 3 is mounted on the downside of shell 1, and LED light-emitting component is equipped in shell 1, penetrates Glass lamp shade 3 illuminates downwards；The mounting base 2 is located at the top of shell 1, is fixedly connected between mounting base 2 and shell 1 perpendicular Straight fixed spool 4 offers threading hole 6 in the lower end corresponding housing 1 of fixed spool 4, makes to connect in fixed spool 4 and shell 1 It is logical, so as to which electric wire etc. is penetrated into shell 1 by fixed spool 4.

The fixed air duct 5 for being set in 4 outside of fixed spool, fixed air duct are further fixed between the shell 1 and mounting base 2 The distance between 5 inner walls and 4 outer wall of fixed spool are 20~40mm, and the material of fixed air duct 5 is stainless steel, fixed air duct 5 Outside fixing sleeve is equipped with bearing 13, and bearing 13 is made of outer ring, inner ring and steel ball, and the upper and lower side of fixed air duct 5 is fixed It is arranged with bearing 13, the outside of bearing 13 is fixed with the rotary sleeve 9 coaxial with fixed air duct 5, so that rotary sleeve 9 is existed by bearing 13 Horizontal direction rotation, is fixedly installed with sealing ring 14 on the opposite side of two bearings 13, makes to seal between two bearings 13, Internal gas is avoided to flow out from bearing 13；It is uniformly provided on corresponding 5 side wall of fixed air duct between two bearings 13 several A first air holes 8, and is connected in fixed air duct 5, and air inlet cylinder 10 is fixedly installed on the rotary sleeve 9, and air inlet 10 face of cylinder is solid Determine the first air holes 8 on air hose 5, enters the air for entering the wind entrance in cylinder 10 in fixed air duct 5 by the first air holes 8, Vertical wind deflector 12 is fixedly installed with by fixed connecting rod 11 in the other side of rotary sleeve 9, enters the wind cylinder 10 and wind deflector 12 on same level straight line, changes the direction of air inlet cylinder 10 by wind deflector 12, convenient for air inlet in air inlet cylinder 10；The fixation Several the second air holes 7 are offered between air hose 5 and fixed spool 4 on corresponding shell 1, the second air holes 7 enters inside Air is sent in shell 1, cooling to inside；Several exhaust vents 15 are offered in the bottom of shell 1, by the air with heat Discharge.
