The utility model discloses a realize through following technical scheme: an LED street lamp with enhanced heat dissipation comprises a lamp shade shell, an arc-shaped lamp shade connected with the lower end of the lamp shade shell and an LED lamp strip arranged in the arc-shaped lamp shade, wherein heat dissipation holes are respectively formed in two sides of the top of the lamp shade shell, and a shielding plate with one end fixedly connected to the top of the lamp shade shell is arranged above the heat dissipation holes;

a transmission mechanism is arranged in the lampshade shell and comprises roll shafts which are respectively arranged at the upper side and the lower side of the two ends in the lampshade shell and a transmission belt connected with the four roll shafts, one end of each roll shaft is inserted into the small bearing seat fixedly connected on the inner side wall of the lampshade shell, the other end of each roll shaft is inserted into the small bearing seat fixedly connected on the other inner side wall of the lampshade shell, the other end of the remaining roll shaft is fixedly connected with the output end of the micro motor, and a plurality of radiating blocks are distributed on the transmission belt;

a temperature sensor and a controller are arranged on the inner side of the lampshade shell;

and a heat dissipation plate is arranged between the lampshade shell and the arc lampshade.

The micro motor is a stepping motor.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model adopts the technical scheme that a transmission mechanism is arranged in the lampshade shell, and the roller shaft is driven to rotate by the micro motor, so that the transmission belt rotates to drive the heat dissipation block on the transmission belt to rotate, and on one hand, the heat dissipation block continuously brings the high heat at the bottom to the top and is dissipated through the heat dissipation holes; in addition, the rotation of the transmission belt stirs the hot air in the lampshade shell, so that convection is strengthened, the radiating speed is increased, the radiating efficiency is improved, and the service life of the LED street lamp is greatly prolonged.

Detailed Description

As shown in fig. 1 to 2 of the drawings of the specification, the heat dissipation enhanced LED street lamp comprises a lampshade shell 1, an arc-shaped lampshade 2 connected with the lower end of the lampshade shell 1 and an LED lamp strip 3 installed in the arc-shaped lampshade 2, wherein heat dissipation holes 4 are respectively formed in two sides of the top of the lampshade shell 1, convection is formed inside and outside to dissipate high heat of the lampshade shell 1 out of the shell, a shielding plate 5 with one end fixedly connected to the top of the lampshade shell 1 is arranged above the heat dissipation holes 4, so that rainwater impurities are prevented from entering the shell, and the service life of a lamp holder is prolonged;

a transmission mechanism 6 is arranged in the lampshade shell 1, the transmission mechanism 6 comprises roll shafts 61 respectively arranged at the upper side and the lower side of two ends in the lampshade shell 1 and a transmission belt 62 connected with the four roll shafts 61, one ends of the four roll shafts 61 are inserted into small bearing seats 7 fixedly connected on the inner side wall of the lampshade shell 1, the other ends of the three roll shafts 61 are inserted into small bearing seats 7 fixedly connected on the other inner side wall of the lampshade shell 1, the other end of the remaining roll shaft 61 is fixedly connected with the output end of the micro motor 8, and a plurality of heat dissipation blocks 9 are distributed on the transmission belt 62;

a temperature sensor 11 and a controller 12 are installed inside the lamp shade shell 1, the temperature sensor 11 is electrically connected with the controller 12, and the controller 12 is electrically connected with the micro motor 8 (the specific connection mode of the temperature sensor 11, the controller 12 and the micro motor 8 is common knowledge of those skilled in the art, and need not be described any further);
