Examples

As shown in FIGS. 1-2, an intelligent street lamp comprises a lamp post 1, a LED lamp extending outwards from the top of the lamp post 1, and a control box 3 arranged inside the bottom of the lamp post 1. In this embodiment, the top of the lamp pole 1 is provided with a monitoring camera. In this embodiment, the middle part of the lamp pole 1 is provided with a display screen for playing videos. In this embodiment, 1 top of lamp pole is equipped with environmental monitor for the monitoring air condition. Still be equipped with luminance sensor on the lamp pole 1, this embodiment, control box 3 and environmental monitoring appearance, surveillance camera head, display screen, car flow sensor, LED lamps and lanterns wired connection, control box 3 still inserts the commercial power to after carrying out step-down processing to mains voltage, give above-mentioned each component power supply. The environment monitoring instrument, the monitoring camera and the brightness sensor transmit detected data to the control box 3, and the control box 3 controls the illumination intensity of the LED lamp according to the data detected by the traffic flow sensor. The control box 3 sends the data detected by the monitoring camera and the environmental monitor to a management center through a power line carrier communication technology or a wireless GPRS/CDMA communication technology. The management center can remotely control the startup and shutdown of the LED lamp through the control box 3.

The content in the above description is the prior art, and the above description only provides an implementation case of the functions of the smart street lamp, but not an improvement point of the present application, and in practice, the smart street lamp may further include more functions, or only include the above partial functions, and the functions of the smart street lamp are not limited in the present invention.

In the prior art, the control box 3 is generally embedded underground or arranged on one side of the bottom of the lamp post 1, no matter where the control box is arranged, the control box 3 is communicated with the hollow lamp post 1 due to the wire connection.

The main improvement points of the present embodiment are as follows:

an oil cooling system is arranged in the lamp post 1 and used for cooling the LED lamp and the control box 3.

The following technical characteristics are also provided as in the prior art: the top of the lamp pole 1 bends outwards to form a connecting port, and the LED lamp housing 2 is sleeved and inserted on the connecting port of the lamp pole 1 and is hooped tightly by an iron hoop. The electric wire is sent into the LED lamp shell 2 through the lamp post 1 and is connected with the wiring terminal of the LED chip. The LED lamp housing 2 comprises an upper housing and a lower housing, the upper housing and the lower housing are connected through bolts, and a transparent cover is arranged on the lower housing to transmit LED light. The LED chip is packaged on the substrate, the back of the substrate is connected with a metal heat-conducting plate 4 for heat dissipation, and the upper shell is provided with heat-dissipating fins.

In this embodiment, be equipped with the oil cooling system in the lamp pole 1, the oil cooling system includes oil pipe, oil pump 8. For convenience of description, the oil pipe is divided into four parts, namely an oil pipe I part 5 coiled on the metal heat conducting plate 4, an oil pipe II part 6 wound on the inner wall or the outer wall of the shell of the control box 3, an oil pipe III part 7 arranged in the lamp post 1 and an oil pipe IV part.

The liquid inlet and the liquid outlet of the oil pipe I part 5 are respectively connected with the liquid outlet of the oil pipe III part 7 and the liquid inlet of the oil pipe IV part. The liquid inlet and the liquid outlet of the oil pipe II part 6 are respectively communicated with the liquid outlet of the oil pipe IV part and the liquid inlet of the oil pipe III part 7. An oil pump 8 is arranged on the oil pipe to drive the circulation of the cooling medium oil.

The metal heat-conducting plate 4 and the control box are stuck to the oil pipe through heat-conducting viscose glue so as to fix the position of the oil pipe. The inner wall of the lamp post is provided with a pipe clamp 9 for clamping an oil pipe and fixing the position of the oil pipe.

The working principle of the embodiment is as follows:

the LED lamp base plate spreads heat out through metal heat-conducting plate 4, and carry out the heat exchange with the coolant oil in oil pipe I portion 5, the coolant oil through the heat exchange is along with setting up down at oil pipe IV operation, carry to control box 3, because lamp pole 1 highly is generally high, therefore, in oil pipe IV's transportation, the thermal oil of LED lamp has been absorbed and has been cooled down, then transport to the oil pipe II portion 6 that is arranged in control box 3, the heat that control box 3 produced is absorbed once more to the refrigerated oil, then transport up to the oil pipe I portion 5 that is arranged in the LED lamp through oil pipe III portion 7, form the circulation. Because the height of the lamp post 1 is generally high, the oil absorbing the heat of the control box 3 is cooled in the transportation process of the oil pipe III.

Through this structure, realized the cooling of circulating liquid cooling to LED lamp and control box 3.
